The desire to change your car, adapt it to different operating conditions, give a sports spirit or turn into a all-terrain vehicle forces car enthusiasts to go to an unprecedented experiment - to install with your own hands.

But how much is the idea? Is it possible to perform it with the help of girlfriend and in my garage? Let's discuss these moments.

Is it worth it to install a pneumatic suspension on the car?

Let's see what a pneumatic suspension is, and whether it is worth spending money on it.

A pneumatic suspension is an amortization system that allows you to automatically change the clearance of the car without the use of physical strength.

This type of suspension is considered a universal option, which allows you to mount it both on passenger and on trucks.

Installation of pneumatic suspension guarantees a number of advantages:

1. Change of car clearance. To increase (reduce) the lumen does not need to change the springs or make serious alterations. A few minutes of adjustment and suspension sets the desired clearance.
2. The smoothness of the move on off-road. Lack of spring shock absorbers - sensitivity to uneven roads, which requires maximum attention from human side. With a pneumatic suspension easier - oscillation compensation occurs, which reduces the mold of the vehicle to almost zero.
3. Comfort and handling. Hard or soft springs have weak and strengths. The first are suitable for asphalt roads, and the second is for off-road. The advantage of the pneumatic suspension - smoothing the minuses of different springs.
4. No drawdown. Pneumatic suspension ensures optimal clearance even at maximum load, because the clearance easily adjusts to the desired value. So it does not matter how many passengers are inside the vehicle.

Before making a decision on the installation of such a suspension, it is worth considering the number of its flaws:

1. The cost of pneumatic suspension is high, which scares motorists. Money goes to buy pneumatic pillows, air receiver, compressor and other devices.
2. Not maintainability. At the failure of any of the elements of the system will have to change the node in the complex. This leads to additional costs to which not all motorists are ready.
3. Insufficient resistance to the negative impacts of "chemistry" on the roads, frost, heat, and so on. Such factors lead to a decrease in the resource of the node. And if the alcohol is capable of saving, filled into the pillow, then only the installation of original and expensive products will save on the road on the road.

The concept of pneumatic suspension looks like this.

Another scheme.

Install the pneumatic suspension on the VAZ 2110

Statistics show that motorists are more dissatisfied with the product of the domestic auto industry. That is why the number of tuned "nine", "dozen" and other AvtoVAZ models is growing on the roads.

The principle of selection of components and installation of pneumatic suspension for different models of VAZ is almost identical.

For example, take the model 2110.

So, for independent installation of the pneumatic suspension, the following material will be required:

1. Racks.

It is allowed to use the factory racks such as CAAZ with oil filling. Purchase costs - 8 thousand rubles.

2. Pillows pneumatic suspension.

As an option - the use of pillows from the fourth generation, mounted under the cabin car. The price of the question is 3 thousand rubles per piece. For example, such.

3. Receiver for pneumatic suspension.

A gas cylinder from "nine" is suitable in the role of the receiver. He has several advantages - the presence of a check valve, pressure resistance to 22 atmospheres, capacity up to 45 liters.

All these advantages indicate that the car will rise faster. The main minus is a big mass.

Alternatively, the use of a cylinder from KAMAZ by 25 liters is allowed. The cost of buying a cylinder is 2.5 thousand rubles.

For work, two pairs of electromagnetic valves will be required. Pay attention to quality. Devices must withstand up to 25 atmospheres. Price - 350 rubles per piece.

5. Fittings and tubes.

The optimal option is the use of pneumatic PVC tubes used in the brake systems of trucks. The tubes are selected with a diameter of 6 and 8 mm. The first (by 6 mm) is mounted on the inlet valves to the receiver, and the second (by 8 mm) from the compressor to the receiver. The issue price is 35 rubles per meter.

6. Compressor.

Great option - installation of the Berkut P 20 series compressor worth 4950 rubles. Advantages - high pumping rate, reliability.

7. Management.

For valve management, a special system managed by three togglers was used. The first starts and turns off the rear circuit, the second - front circuit, and the third - controls the compressor.

8. Manometer.

In the interval between the receiver and the compressor, a pressure gauge is installed, as well as a separator of moisture and oil. The installation site in the cabin is determined independently. The price of the question is 80 rubles per piece.

Before starting work, it is worth considering the following points:

The installation algorithm of the pneumatic suspension is as follows:

• Install racks. Options are two - to make new holes or use already existing (the second way looks preferable).
• Remove gum and stretch the oxygen tubes. Next, fix them to the body part with the help of clamps. In order not to drill the body, you can use drainage holes;

  

• Next, fasten the tube clamps;

  

• Rear circuit Create over the beam behind the car, and then pull it on it;

  

• The gas valve of the gas equipment required to reset the air and reduce the clearance of the machine, mount the special bracket for fixing the fuel tank. Remember the need for a reserve for a tube that will be required when lifting or reducing the clearance of the machine. The tube will be flexible, so its fixation is performed using clamps;

  

• The installation of the front circuit takes longer, because the tube has to be conducted through the entire car. The main complexity is in the mount. Here you have to spread with brains and find a suitable place for fixing;

  

  

• Pipes from pillows installed in front, drive on the steering traction. After starting them in the motor compartment, put the cross, make the pipe laying, put a reset valve and a GBO valve;

  

  

  

• Connect the wires of the relay, the fuses, fuses, here you will need knowledge in the electrics;
• It remains to check the operation of the mechanism. Here you need to fill the system with air (up to eight atmospheres), close the garage and listen to the system on the fact of leaks. If the ear does not catch anything, it is worth checking the joints of the joints with a soap solution.

Finally, it is worth noting the following points:

It should turn out so.

Install the pneumatic suspension on Mitsubishi Eclipse GTX 3.0TT AWD

On the Internet there is a mass of speculations that the installation of a pneumatic suspension on Mitsubishi Eclipse often leads to a variety of problems. But it is not.

If you properly organize the process and clearly follow technology, then the result will even make demanding motorists.

As an option - installing ready-made equipment from K-Sport or other brands.

But this approach is not rational for the following reasons:

• Costs turn out to be higher than planned;
• The reliability of such a system is minimal;
• The required Remkomplekt has to wait a few weeks, and then months.

Thus, it is preferable to an independent assembly of component materials. Especially since the market is saturated with everything necessary for work.

So, for mounting the pneumatic suspension, five high-quality racks will be required.

To avoid problems and additional costs in the future, it is worth preferred to the original spare parts for the airlessness of the brands of Audi, Volkswagen, Mercedes and others.

It is better to consult with a specialist.

The Berkut Compressor is also required (it is available at a price and is distinguished by the maximum resource).

Work begins with the installation of the rear racks and drill several holes in the body under the spare wheel.

New holes are required to install adapted fittings under pneumatic lines.

What does the valve block look like.

It remains to check the system for tightness. If there are clear "spikes" it is worth checking the locations of the joints and the quality of the fittings.

The last stage is the removal of jacks and testing the car.

If the work is done correctly, the machine takes on softness, problems with overcoming high obstacles are eliminated.

If you get into the pit, the pneumatic suspension behaves worthy and withstands the test.

One of the probable problems is proximity to the tire. In such a situation, it will be necessary to install a spacer.

Separate moment - body level sensors. They have to finish separately and even order special brackets for later installation.

Excellent sensors from Land Rover.

It does not prevent the collapse of the alignment in the middle position of the suspension, after which the routine is leaving, silently passing "lying police", small pits "swallow" and almost not heard in the cabin.

Install the pneumatic suspension on the gazelle

For the installation of pneumatic suspension on the gazelle, the following material will be required:

The greatest complexity in the installation process causes fastening of pneumatic powder. This is the moment and pay attention.

The algorithm is the following:

• The cross is collapsed with the stops installed on it to install pneumatic pillows. To cook the crossbar is easy - use the 16th Schwell;
• Prepare a pad under the pillow. If the springs caught, then the car should be raised by jacks;
• Installation starts on top. First, the top is fixed, after the pillow swinging and the holes are drilled over the docking of the spills. Note that the work should be performed on the working height. Also make sure the pillows are at maximum distance from the center. It is necessary to eliminate the friction of product springs under load;
• Installing pillows on the front axle is not required if the car has a short base. If the base is long, then without performing such work it is not necessary.
• Installation of pillows is made in two ways - over springs (in the central part of the beam) or straight to the spring. Both options have cons. So, if you perform installation behind the beam, then when the steering is unscrewed, the re-installed node is possible. If you put the design closer to the central part of the beam (above the springs), then the front of the car is being launched;
• The brand is branded to the frame of the Gazelle, and a special chamber design is provided over the springs. So you have to work welding to eliminate possible risks for pneumatic suspension;
• Pillows on the front and rear axles are installed on top, after which they pump up to the desired height. As soon as the position of the holes, drill holes and put the pillow.

See more detail in the photo.

The result of the work is a rigid front suspension. To add softness, it is worth a parallel to pillows to make receivers with the use of thick tubes.

The task is standard. Increase comfort and protect the expensive front springs from breakdown. On the car, there is already a progressive regular pneumatic suspension of the rear axle. Air generation with a regular pneumatic system to which the control of the air suspension of the front axle was connected.

Due to the fact that the car is quite heavy, and the transported load exceeds the nominal value of 7 tons, it was decided to establish pneumatic oil 400190 with internal buffer. The kit has already worked more than 15 tons and at the moment launched into serial production. The client of the work of the equipment is pleased.

Installation of pneumatic suspension on Mercedes Benz Sprinter 513 W906

Car - chassis with high commodity booth. Springs change once a quarter in a consequence of constant overwhelms. Also, due to the high sail, the car during the movement along the speed highway is dangerous. The solution of all the stated problems takes on a pneumatic suspension from the company Air-Ryde. Install the standard set of axial pneumatics

This device in the automotive industry is used for about 60 years. Initially, it was installed only on trucks and semi-trailers. But progress does not stand still, so the pneumatic suspension now put on passenger cars. True, not all. And what about the one who wants to ride with comfort, but did not save money on the business class machine? The answer is simple: put the pneumatic suspension yourself. How to do it, we will talk today.

What is a pneumatic suspension

If short, pneumatic suspension is a device in which there are no spring shock absorbers. The parameters of this device driver can adjust at its discretion, and this can be done right on the go. When installing the pneumatic suspension, standard springs, springs and torsion are replaced with reinforced rubber pneumatic pillows. The elastic element in pneumatic powders is air injected by a special system, which includes the following parts:

1. Compressor.
2. Switching system valves.
3. Control unit.
4. Receiver.

According to the method of controlling the pneumatic suspension are manual and automatic.

• in manual control suspension, the car owner independently sets the magnitude of the traffic lumen (usually such devices are complemented by pneumatic depreciation racks, so the driver can manually install not only clearance, but also stiffness suspension);
• in an automatic suspension, the electronic control unit itself will select the value of the road lumen, based on the parameters such as speed, mass, side roll roll, etc. If the adaptability of the automatic system is very high, then under certain conditions it is able to seriously lower the center of gravity of the machine and repeatedly improve handling, especially on turns;

By the design of the pneumatic suspension are divided into:

• single-mounted. In them, pneumatic powders are installed on one of the axes;
• double-circuit. Here the pillows are also installed on one axis, but the pressure in them may be different;
• four-circuit. They are considered the best (and most expensive), since microcomputers are used in these suspensions, pressure sensors and a system of four separate valves, one for each wheel;

The most popular place to install the receiver and compressor in the passenger car is the trunk, or rather, a niche of a spare wheel. Of course, the spareswear will have to either move to another place, or remove completely, compensating for its lack of tire sealant.

Is it worth installing the pneumatic suspension?

If short: yes.

Now understand more.

What depends on the comfortable ride without shaking and strong rocking the car? Here are two parameters: the mass of the machine and the rigidity of the springs of the shock absorbers. If the car is light, and the rigid springs - the driver is provided. If the car is heavy, and the springs are soft - a pitching is provided as in the sea. This problem is also aggravated by the fact that it is impossible to bring the rigidity of the springs and the mass of the car in principle, since the mass is constantly changing, because in the car there is a different number of passengers, it can transport additional cargo and so on.

Change the rigidity of spring shock absorbers is also impossible. And moreover, it falls over time (due to metal fatigue), and along with rigidity and the road clearance of the car decreases.

To regulate the stiffness of the shock absorbers and a pneumatic suspension was created, the elements of which are able to adapt to the constantly changing parameters of the car, providing a comfortable driving driver in any conditions. Here is its advantages:

• machine clearance and stiffness of its racks are automatically adjustable;
• the machine becomes more resistant to overloads: In the case of a large load, the rigidity of the racks rises to a maximum, which avoids damage to other suspension parts;
• improving manageability: driving becomes more smooth, the car roll on the deviras is minimal;
• when using a four-finished automatic suspension, the longitudinal roll of the car also seeks to a minimum that makes ride even more comfortable;

Cons of this device also have:

• pneumatic shock absorbers are not refundable. In case of failure, they can only be replaced;
• rubber of pneumatic powder is sensitive to cold and pollution (it will be described in more detail below);

Here you should mention both hydraulic suspensions. They perform the same function as pneumatic, but their elastic element is a special fluid. And the main difference in hydraulic acid is their increased reliability (and a very high price, which is unlikely to afford an ordinary car enthusiast. For example: The resource of the pneumatic suspension is an average of 200 thousand km, while the hydraulic drill can easily pass to 400 thousand km.

Of all the above, a simple conclusion is followed: a pneumatic suspension is a good alternative to stock springs and hydraulics with its transcendental price.

Pneumatic suspension installation process

Before starting the installation of the pneumatic suspension, it should be determined that we need to work.

Tools and materials

Sequence of action when installing pneumatic suspension

• the trunk of the car opens, a spare wheel is extracted from the niche;
• on the side walls of the trunk there are plastic plugs holding a rug. They are approaching flat scolding and removed;
• after that, the rug itself is removed. Access to the shell nuts and holes that will be required to lay the wiring;
• the compressor connects to the control unit and the receiver as it is indicated in the instructions. After that, the collected design is installed in a niche of a spare wheel;
• next, wiring is connected to the receiver and compressor. Connection is carried out in strict accordance with the guidelines on the wire labels;
• the connected wires are collected in one harness, which is displayed in the passenger interior through a hole under one of the rear seats;
• next, the harness is laid along one of the walls of the cabin, under the mats and is displayed in the engine compartment;
• there wires are connected to the battery, mass and to the fuse block as it is indicated in the instruction manual for the control unit of the air suspension;
• now one of the rear wheels is subdominated, after which 4 lower mounting nuts on the rear rack are unscrewed by 22 using a horn key;
• with the help of the end head on 24 through the hole in the trunk, the upper fastening nut of the rear rack is unscrewed;
• after unscrewing the top nut, the rack is extracted. A similar operation is carried out with the second rear rack. Pneumatic racks from the pneumatic suspension set are installed at the place of the racks;
• to remove the front racks on each of them, the front wrench is unscrewed by 4 mounting nuts;
• next, the brake system hoses are disconnected and the hoses are removed, manually disconnects the Plug of the ABS sensor (if there is available in the machine);
• the front racks are extracted, the racks from the kit are installed on their place and are fastened reliably;
• pneumatic lines are connected to the compressor, the receiver and the control unit in accordance with the instruction, after which the hoses are output through the hole in the trunk;
• the resulting air line is displayed in the engine compartment and connected;

Control of pneumatic suspension

Any high-quality pneumatic suspension is supplied with a controller that is installed in the cabin. On his display, the driver can see the pressure both in pneumatic powder and in the receiver. Units of pressure measurement The auto owner can choose at its discretion. The control units of high-quality four-constructive suspension allow drivers to choose from several pre-installed modes with a certain clearance (in particular, at the air-lift pneumatic suspension, about which it was above, such modes 8). Select the desired driver mode can literally with one click the button.

Moreover, over time, the driver will not need to close with the buttons at all, since the system will gradually "study" the car, "accustomed" to the conditions of its operation, to the style of driving a car owner and will keep the optimal pressure in pneumatic powder.

Turning off the pneumatic suspension is made from the same controller. When the system is disconnected, the system sets the average magnitude of the road lumen, after which the pneumatic powder starts working as ordinary spring shock absorbers.

Pneumatic shock absorbers are the main advantage of pneumatic suspension. But they are their weak place. This moment is especially clearly manifested when the machine is operated in conditions close to extreme.

Pneumo immorters have 2 enemy: sand and cold.

Independent installation of a pneumatic suspension - the task for advanced motorists who know exactly what they do. The newcomer, severly behind the wheel just yesterday, such a task is clearly impossible. But the experienced motorists also allow mistakes. The most common - homemade, created on pillows ordered via the Internet from China. The quality of rubber in such products, as a rule, leaves much to be desired. And about what the management problems can cause is already written above.

German manufacturers strive to constantly upgrade the design of their cars, and therefore, the Mercedes W220 is rarely repaired by the repair of the Pneumatic suspension. Nevertheless, it is necessary to have an idea of \u200b\u200bboth the very design of the suspension and the stages of repair, when it really needs.

1 Features of the design of Mercedes W220

Pneumatic suspension allows not only to simplify the control of the machine, but also provide additional safety. It is possible to quickly change clearance. The control unit allows you to maximize the use of lifting capacity, which helps solve the problem of stiffness. Mercedes has a suspension that makes it possible to choose the best mode of operation. For example, for off-road and country roads, the most soft is "comfort." The city will fit the standard mode, and for a good highway - "Sport". Also on the W220 will not be difficult to enter the parking lot on the border, get out of the deep gauge.

Instead of traditional springs and torsions, pneumatic suspensions are supplied with air cylinders. The compressor, in turn, will supply the required amount of air based on the mode. This allows you to achieve maximum road lumen at 307 mm, and therefore, you can overcome the depth to 600 mm.

Pneumatic bullons in the car are calculated for both front and rear axles. It helps the pneumatic system, which includes a compressor, receiver (compressed air tank) and control unit. The size of the valves, the diameter of the airway, the volume of the receiver and the pneumatic bullons is selected specifically for the W220 so that the compressor worked for complete power.

Usually Mercedes can drive at least 100 thousand kilometers before there are problems with air suspension and repair is required. But here you should consider the quality of the roads for which you have to ride. Therefore, it does not hurt every 50,000 kilometers to make a diagnostic inspection.

2 The main problems of the pneumatic suspension

To avoid premature repairs, you need to pay attention to the characteristic problems that may arise:

• The rear axle begins to drop, especially when the engine is shoved;
• When starting, the reverse process takes place, while at the very beginning the rear axle rises, and then the front;
• High speed leads to the fact that the front axle is descended, and when braking it raises sharply;
• The clearance of W220 also constantly floats and it is difficult to adjust, besides, there is a small disk.

Often, the problems of the pneumatic suspension begin with air leakage. This is due to the work of the valves and the connecting elements, the compressor ceases to function normally due to wear of the rings. Plus to all the antifungal funds, which sprinkle roads in the winter, fall into pneumatic bullons and this leads to premature corrosion.

3 replacement of pneumatic in W220

The situation occurs periodically when the replacement of the pneumoter is required. Mercedes, as you know, has different modifications of the pneumatic suspension. For example, for W220 Airmatic, it most often has to change the rear rack and here it is important to comply with the phase out. However, this repair can be performed by your own. This will require the following:

The upper part of this element of the pneumatic suspension is sealed with glue. Over time, it cracks, and the air lock begins to pass the air. The body is constantly lowered, therefore, it is necessary to repair with the replacement of the rack.

4 Elimination of possible malfunctions in Mercedes W220

Some other problems arise that to a lesser extent affect the control unit. More often, the repair touches the pneummobalones and plugs, since they constantly fall aggressive substances, dirt and moisture. The receiver case may even crack, or the connecting tube of the system is pulled out (it, like a balloon, should be replaced). It is necessary to check the valve status, since the coils sometimes burn out. Even a small distortion will require calibration and special equipment will be required here. But the compressor, on the contrary, it is much less frequent.

Mercedes requires a periodic passage of computer diagnostic inspection. Therefore, serious repairs or in the event of a small problem at Mercedes, unlike competitors, is not always obligatory. In addition, the W220 air suspension has good pneumatic resistants that automatically adjust the control unit. Everything will depend on the roadbeds and conditions, while nothing will prevent the manual control (for this it is enough to press the switch located on the dashboard).

The car has four damping modes. They are designed to monitor the coating condition and provide a soft stroke and control. For example, at a speed of 140 km / h, the clearance will automatically decrease to 15 cm, and 70 km / h follow the recovery of the level.

Diagnostics and prevention will prevent the occurrence of many problems, and the timely replacement of faulty elements of this system will allow you to ride on any tracks absolutely calmly. Small repairs can be performed by the own forces, but if you encountered more serious problems, it is better to trust professionals - Mercedes W220 deserves this.

X You still think that the diagnosis of the car is difficult?

If you read these lines, then you have an interest to do something in the car and really savebecause you already know what:

• One hundred breaks big money for a simple computer diagnostics
• To find out the error you need to go to the specialists
• In the services there are simple wrench, and good specials do not find

And you of course tired of throwing money on the wind, and about riding a hundred constantly can not be and speech, then you need a simple roadgid S6 Pro auto repairner, which connects to any car and through a regular smartphone you will always find a problem, pay off Check and not bad Save !!!

We ourselves tested this scanner on different machines And he showed excellent results, now we recommend it to everyone! So that you do not fall into a Chinese fake, we publish a link to the official website of the autoskner.

Hello everyone!

On W221, the pneumatic suspension is set to all models without exception. The system consists of a compressor, a block of valves and 4-line pneumatic racks in which there is an oil filled with oil. Most often dies just the mechanical part filled with this oil and the shock absorber appears.

I noticed that the car had long rises somehow slowly. And, about 1.5 days, it is lowered if the car is in a stationary state.

Many, by the way, think that Kakraul (!) How bad. But the dealer immediately said that all Mercedes are lowered. Some slow, and some faster. At the same time, if after starting the engine, the suspension is returned (rises) into normal position, they say, "this is normal. Absolutely normal."))

And so, one day, she did not rose. Well, okay, I thought and put the car and went to Porsche. But, damn, began to get cold and the charter of staring about Mercedes (Geya) I decided that time came!

The price of the new compressor to Avito on average 28 thousand. It changes quite easily. Replace in any service in 30 minutes. Well, or you can change yourself during the same time with the presence of desire and tool. And many will say Fuuu ... Himself .... but! Do not forget that when W221 falls on the belly to move on it. It is impossible for you and you need a tow truck! And this very evacuator can not always come to the place where the suspension died. I know the case when people changed the compressor right in the courtyard of a residential house as the tow truck could not squeeze through 5 dozen car parked on borders. Therefore, all owners of W221 will be useful to familiarize themselves with this video.

I have a Mercedesian diagnostic computer SD-Connect which I immediately said that the compressor does not work, and the diagnostic test showed that it does not create any pressure.

By the way, on the same Avito full ads from the services that offer to change your having compressor to restored from 12-16 thousand rubles. And so, a person from the very first service where I called (in order to evacuate the car to them) by name Valery (God for him He health) I said: - Check the fuse. (!)

If you open the hood, the box with fuses and the relay is on the right of the windshield. She is on 4 screws. We remove and (sorry did not take a photo) In the case of my S350, the desired fuse is located on the side of the radiator lattice edge acourate in the middle. The fuse 40a orange and very large. It is located between the two the same in size, but different in the color of the fuses.

It is worth 218 rubles from the dealer.

And yes, the pneuma came to life !!

But the fuses are just not lit. Moreover, such an ampera. So something is not bad in the motor itself begins to occur. This can happen if the motor was very hard .... and what can he be hard? And here (and 99% of the owners do not even know about it) I remembered the existence of the filter of the pneumatic suspension. The filter has been hammered, the motor is spinning, the air goes a little, it works longer than usual, strains, it is sleeping, heats up, starts to consume a current more than it is supposed and the fuse is striking. Realistic such option? More than!

I will immediately say that there is also a relay in the same box. It in 90% of cases sticks out, which leads to constant and non-stop operation of the compressor. And then it will be either ba-bah (and you will hear it and well if a diaper will be dressed on you) with the replacement of the valve block or the same fuse for a start.

The dealer filter cost 882 rubles.

Looks like that

In the near service I was changed to me within 15 minutes while I went for coffee. The price of a question is 1000 rubles. It is located there where and the compressor. On the raise, it is more convenient to remove the front lower protection of the bumper, and on the ground - the front right wheel and subsidence.

After replacement, the machine began to rise markedly faster, and the compressor intervals became shorter.

I did not laugh and took the old filter home and sawing his engraver inside.

Spare parts at the dealer:

I took 15 minutes to write this report, while I am sure that he will save tens of thousand rubles not to one owner who will be readily read. Do not forget to share useful and interesting articles. Do good!))

Thank you for the inconvenience!))

Installation of pneumocomplekt:

Pneumatic suspension kit on Mercedes Sprinter 309; 311; 313; 315; 319; 324; 209, Volkswagen Crafter 35 is installed in addition to standard springs and does not make changes to the regular suspension elements. Therefore, this kit does not require making changes to the TCP of the car. Pneumatic powder for Mercedes-Benz Sprinter 309; 311; 313; 315; 319; 324; 209, Volkswagen Crafter 35 is placed between the frame and springs on special mounting plates coming in the kit. The upper fastener plate is placed on the frame in the standard holes. The bottom mounting plate is placed on the bridge.

Principle of operation of the pneumatic suspension:

When filling the pneumatic climbers with compressed air, the load is redistributed with the spring to pneumatic elements. Next, when the car moves along the irregularities, the air in the pneumoshushki is compressed even more, which will allow you to compensate for vibrations and a split. Depending on the pressure in pneumatic oil, you can change the behavior of the suspension.

Recommendations for installing system components and service periods:

• When installing equipment, it is necessary to make sure that the parts of the suspension, the brake system and other elements of the car will not damage the pneumatic elements and the feeding highways
• After assembly, check the system for air leakage (using a soap solution)
• Re-check for leakage after 100 km after installation

Attention! Minimal operating pressure in pillows 1 bar! Periodic washing of pneumatic elements significantly reduces the likelihood of their failure from a sticking abrasive (sand, stones, dirt). The error in the measurements of the pneumatic oil is not more than 5%. If the pressure is exceeded, more than 8 bar, the parameters of diameter and height will not change (no load pillow). In the process of long-term operation, the parameters of the external diameter of the pillow may increase by 10%.

The technical parameters of the product, as well as the illustrations are only an introductory character. The manufacturer of the product reserves the right to retreat from the stated parameters without prior notifications.

Diagnostics of a set for air leakage (area of \u200b\u200bdiagnostics and action to eliminate leaks):

With the correct assembly of the aircraft set, the permissible drop in pressure with pneumatic bullons 1 bar for 72 hours (GOST position)

If the system pressure drops into greater values \u200b\u200bor for shorter periods it is worth a diagnosis of leakage of threaded connections, connecting the air tube on the pressure gauge (if available), as well as the tightness of the pneumatic oils themselves.

The means for diagnosing leaks is a soap solution of water. When leakage is detected, eliminate its tightening of the threaded connection with minimal effort or disassemble and assemble the node using the sealing material (fum-tape, thread, threaded sealant).

Mercedes Vito is a very popular minivan in Russia. This machine is in demand primarily due to powerful and reliable engines, as well as a comfortable suspension. By default, screw springs in front and rear are installed on the "Vito". As an option, the manufacturer could recycle minivan with air suspension. But there are very few such modifications in Russia. Most of them already have problems with suspension. But what if you want to get a minivan on the pneuma, which was originally walking with the clips? Exit only one. This is on Mercedes Vito. It is possible to do it with your own hands. What does the air suspension give, how is it arranged and what receives feedback? All this and not only read in our current article.

Characteristic

So what is "pneuma"? This is a suspension suspension that implies air cylinders.

They are elastic elements in the chassis and allow you to change the clearance depending on the volume of the filled air. Cylinders are installed instead of springs, and in our case - screw springs.

Why is she so popular?

First of all, such a suspension is popular thanks to its energy intensity. There are many opinions about this, but how many levers in the running either have been used, the air cylinders are softer absorb shocks, rather than spring (and about the springs and it is not worth talking). What else are the advantages of such a system? If this is a cargo "Vito", the installation of such a suspension will increase the carrying capacity of the machine. So, with full loading, the car will not save as before.

Design

The main component of any pneuma is air cylinders. Their name is pneummators. It is these details that perform the role of elastic elements in the suspension. Cylinders take on all shock load. In addition to them, the car body itself is held. These pneumutors are made of dense multilayer rubber and are able to withstand huge pressure. On top and bottom on the pillow there is a metal spacer, thanks to which the part is mounted to the body and pendants. This is a kind of platform for the placement of air springs. The cylinders themselves have a cylindrical shape, but they can change their height. Due to this, the car clearance is adjusted.

Compressor. As noted in the reviews, it may not enter the pneumatic suspension. As a budget counterpart, the installation of nipples of swaps is proposed. What gives the compressor? This item produces podaching of cylinders. The unit is connected to the regular onboard network of the car. Also, the compressor has its own "Cutter". When a certain pressure is reached in the receiver (usually ten atmospheres) it automatically turns off.

What are receivers? These are hollow metal containers containing compressed air. As noted in the reviews, a five-liter receiver is enough for Mercedes Vito. It is not too big and enough for several cycles of lifting-lowering the body. The receiver and compressor of the Mercedes Vito pneumatic suspension can be connected together. Often manufacturers supply ready-made compressors in which there is a receiver. It is very convenient. If the installation of a pneumatic suspension is made on Mercedes Vito with their own hands, do not need to think where and how to position these items. It is enough to fasten everything in the cabin (for example, under one of the seats).

Also, the composition of the air suspension includes various hoses, fittings and electromagnetic valves. The latter allow air to move through the system at the right moment. And it connects all to one control panel. Usually it is fixed near the driver's chair.

What do owners say?

As noted in the reviews, the set of pneumatic suspension on "Vito" should be purchased for several reasons. The first is high smoothness. With such a system, you can make the stroke of the suspension even softer, without changing the rubber profile. The second reason is good handling. How much baggage is neither putting, the car will be perfectly controlled in turns. The suspension can be made rigid and soft - it is enough to adjust the pressure in the circuit. The third reason is the ability to adjust the clearance. For someone, it helps it easier to overcome snow drifts, and someone puts such a suspension to attract attention. On completely lowered pillows and beautiful disks, such a car looks very attractive.

At any time, the car can "drop" to the ground and return it to the transport position. The process of raising the pneummator does not take more than ten seconds. But this concerns only those systems where there is a compressor and receiver, they say in reviews. A set of pneumatic suspension on "Vito" with the nipple and without a receiver makes the owner carry a pump for pumping. Otherwise, not to change the configuration of the chassis. As they say in the reviews, the set of pneumatic suspension on "Vito" is better to take with a compressor. After overpaying it once, you will not suffer with a rumor system through nipple, especially in winter.

Varieties

Pneumatic suspension is divided into several types. So, exist:

• Single-mounted system. This is the simplest and cheap suspension scheme. In this case, two pillows are controlled from a single valve. A single-circuit system is installed only on the rear axle. Among the owners of Vito is the most popular option. The machine will not "goat" on the road, when empty, while - well managed with full loading.
• Double-circuit. Such a system is placed on both axis of the car. What is the feature of such a scheme? Here are somewhat different on the "Vito" the cylinders are set for each wheel separately. But they are independently managed by pairs. The driver can lift or lower separately only two front or two rear pillows. The cost of such a system is approximately 2 times higher than that of the previous one.
• Four-circuit. This is the most complex and expensive scheme of the pneumatic suspension on Vito. Its device assumes the presence of a complex control panel with a set of electromagnetic valves. Air supply is carried out from the receiver or compressor directly. But if two pillows were pumped at once in the previous case, then it seems the ability to control each pneummatory individually. The cost of the four-kinth system by 50 percent is higher than that of the previous one. But as noted in the reviews, the pneumatic suspension on the "Vito" of such a plan will be superfluous. For comfortable control of a sufficiently dual-circuit system.

Cost

The price of the fiscal air suspension itself for Vito is 34 thousand rubles. This is a single-mounted system with a nipple podachka, without a receiver and compressor. The kit includes:

• Plastic tubes.
• Fitting.
• Adapters for nipple.
• Floor.
• Air cylinders in the number of two pieces.
• Set of mounts for the rear axle.

Additionally, it is proposed to install a compressor with solenoid valves and receiver. Such an option is worth about 25 thousand rubles. But as noted in the reviews, such a set of pneumatic suspension on Vito Mercedes will be the most optimal.

As for the two-kinning system, it will be more expensive for 30 thousand rubles without taking into account the receiver and compressor. Well, the price of a four-kinning suspension comes to a hundred and above, depending on the brand of cylinders and other components.

Characteristics

Let us consider what a pneumatic suspension has a characteristic:

• Air springs diameter - 11 centimeters.
• Operating pressure range - from three to eight atmospheres.
• The minimum allowable pressure is one atmosphere. If you exploit the system with navalized pillows, they will quickly come into disrepair, even if the pneumators will be made of solid and strong rubber.
• Admissible lifting force - one and a half tons per pneumatic element at a pressure of 10 atmospheres.

Typically, an annual warranty from the manufacturer is provided to the suspension set.

How is the pneumatic suspension on "Vito"? Process description

This procedure can be made both independently and using the hands of specialists. The main difference in the installation of the pneumatic suspension on Mercedes Benz Vito is that the cushions are the main elastic element, and not auxiliary, as on the Sprinter and other commercial cars. Here the pneumus is installed in the place of the factory screw springs. And that the item gets tightly in a cup, special metal spacers are provided. What a ready-made pneumatic suspension looks like "Mercedes Vito", the reader can see the photo below.

Thus, the cylinders are mounted between the lever and the body spar. Additionally, it is not worth strengthening the design. Everything is installed on factory places. So, the first thing "Mercedes-Benz Vito" is put on the lift or subdomains on a flat site. It is advisable to unscrew the lower mounting of the shock absorber. It is necessary in order to remove the old spring. If it does not succumb to it, a special springs puller should be applied. At the next stage, you can start installing the pneumatic suspension on Mercedes Vito. In the upper and lower part, the metal spacer is fixed using a powerful bolt. It is necessary to strictly align the pillow, there was no distortion. Only so the suspension will work normally on Mercedes-Benz Vito.

Next, you can proceed to laying air mains. Please note: for security purposes, they should not intersect with brake tubes. You can fix highways on plastic screeds. After that, it is necessary to connect outputs with solenoid valves and compressor. You also need to pave the wiring on the control panel, which will be located in the cabin.

How further is the installation of pneumatic suspension on Mercedes-Benz Vito?

Then you need to connect the compressor to the car network. After that, you can start the system. The compressor pumps air into the receiver, after which the cylinders will be filled with oxygen. Depending on whether the solenoid valve is open or closed, we will lower or raise the suspension.

Installing without receiver and compressor

When choosing a budget system, you need to decide on the location of the podchock nipples. They can be installed anywhere, for example, under the passenger seat or at the bottom of the glove box. These nipples have the same form as on the usual wheel. And the podachka will be made through a 12-volt pump that works from the cigarette lighter. Installation algorithm is identical. First extracted old springs, then cylinders are mounted and fixed on both sides by bolts. Do not forget about the shock absorber.

It is necessarily secure back, otherwise the routing will be colossal. After that, the air line is laid in the salon. Using adapters and T-shaped fitting, we connect both triggers to the overall conclusion. So we will have a single nipple, which at the same time and evenly pumps two pillows. On this installation of the pneumatic suspension is completed. It can be started.

Before you drop the car from the lift or jack, you need to check the tightness of the system. To do this, the cylinders should be met up to ten atmospheres and prepare a soap solution. With the help of brushes we apply it to important compounds. In the presence of bubbles, we drag the fittings even stronger. And so as long as there is no such tributes in the system.

Service

So that the new suspension served as long as possible, she needs periodic care. On the eve of the winter it is recommended to rinse the dirt from the cylinders and process the rubber with silicone lubricant. So the material will not be so solid at a minus temperature and will not collapse from friction with himself.

It is the dirt that causes the etching of the pillows. It works like abrasive, forming small damage, cracks and donkeys. Over time, they will grow into holes, through which the air is seeping outside under pressure.

Conclusion

So, we found out what a pneumatic suspension is and what the advantages of its installation on Mercedes Vito. As you can see, it is a very useful acquisition. But you need to choose the system correctly. Do not overpay, buying a four-king system for one hundred thousand. But it is not necessary to save excessively, otherwise one day you just get tired of pumping cylinders through nipple. The most optimal option is a single-mounted system with a complete set, which includes cylinders, valves, receiver and compressor.

Airmatic pneumatic suspension has been widely used on Mercedes W220 as standard. As an option, an ABC active hydraulic model was installed on it (code 487) on S500 models, and the S600 was walked only with Active Body Control. Nevertheless, the rest of the models were obtained from the airmatic pneumatic plant, which provided both static and dynamic support with four pneumatic vehicles. Each rack is a pneumatic balloon and a shock absorber collected in one block. The airmatic rack serves air from the air compressor located behind the front bumper of the car near the front wheel. On the opposite side, the central tank that maintains pressure through the pneumatic line and the valve block. The valve block is connected to a computer that controls the pressure in the system, the vehicle weight required by the height of the vehicle, its position (angle) at the moment and then sets the road clearance, respectively with this data.

Advantages of airmatic pneumatic suspension

1. High level of traffic safety and driving
2. Adaptation of suspension stiffness to road conditions and driving style
3. The center of gravity of the car decreases, since the clearance automatically decreases at a speed above 70 km / h
4. Due to the decrease in clearance - the aerodynamic resistance of the car and fuel consumption decreases
5. Individual adaptation: an increase in the clearance of a car on bad roads and, if necessary, moving through obstacles; Two possible levels of stiffness of the pneumatic suspension for comfortable or sports styles of driving in cars produced up to 08.1999; Three possible levels of stiffness of the pneumatic suspension for a comfortable, sports and extreme driving styles on cars produced after 09.1999

System functioning

Airmatic pneumatic suspension is not as advanced as ABC, but it responds to changing the road situation and requires quite a lot of data in order to ensure proper operation of the system and comfort for passengers.

Normal mode of operation (engine is established): When the car is in a fixed state, the level is adjustable if there is a difference between the height of the front / rear axes more than +/- 10 mm. Measurement is performed when opening the door or lid of the trunk.

During movement, the level is reconfigured if there is a difference in the clearance along the axes reaches more than +/- 20mm. During the rest of the time, the level is adjustable to +/- 10 mm every 15 minutes.

Depending on the situation, the pressure in the system is maintained both compressor and high pressure tank (receiver). Compressed air from the tank is used only when it is necessary not to download air into the tank too often. This happens, for example, if the height of the car drops below the critical level when the vehicle is loaded, or if the driver switched the system to the "Enlarged Road" position. The pressure from the receiver is also used when the car is in a fixed state to minimize the noise. In the standard situation when the vehicle is moved, the air in the pneumatic rack comes directly from the compressor.

Reducing the car clearance is recognized by the control module from the body level sensors when the car is loaded. When the electromagnetic valves are triggered, the air is fed to the front, or rear axle, while your Mercedes-Benz reaches a given height. In addition, the pressure reset valve opens to reduce the pressure in the rack when the car is unloading (if the lock system does not work).

Function "Wake-Up" (everything happens within 1 minute)

A parked car "wakes up" before the engine is started. The airmatic control module with ADS receives signals from the door contact sensor, or the sensor on the trunk lid, indicating that the driver may immediately start the engine and drive through the car. The current level of the vehicle is immediately checked and adjusted if it is necessary. The clearance of the car on the front axle is considered critical if the complete wheel turnout cannot be guaranteed. In this case, a message is displayed on the multifunctional display in the instrument combination to warn the driver: "Stop Car Tooo Low".

If the control module is "woke up" (for example, opening one of the doors), the period of free time occurs before the driver launched the engine during which the clearance of your Mercedes is adjusted. This reduces the waiting time required for level correction and prepares the car to go more quickly. Pressure in the general receiver is used to lift the car. The compressor is used only if the receiver is empty, the following conditions are performed: if the car clearance is reduced by more than 30 mm, it rises to normal air from the receiver (if the residual pressure in it is\u003e 11 bar). When a vehicle clearance fall< -65 мм и при остаточном давлении ресивера 12,4 bar, а далее – воздухом из ресивера.

If the car level rises more than 10 mm during unloading, it descends to a normal level by reducing pressure in pneumatic resistants.

When the ignition is turned on, everything is the same, but without a limit of time. When the ignition is turned off, the system monitors the pressure in the receiver so that it is enough to "Wake Up" mode - about the same thing was in the old W126, which injected the vacuum in the center of the Central Castle - coming out of the car, you heard a buzzing pump that carefully cared for Vacuum before your next visit.

The functioning of the airmatic pneumatic suspension with the ADS control module can be divided into the main steps:

1. Obtaining data from sensors for subsequent processing
2. Logic data processing issuance of "orders" system
3. Security chain

Data obtaining

The following input signals are processed by the logical component and are used for calculations or to provide additional information:

1. Calculation of the vertical acceleration of the body
2. Getting signals from body acceleration sensors
3. Calculation of car speed
4. Reading car speed data
5. Comparison of data with speed status signal
6. Calculation of the longitudinal and transverse acceleration of the body
7. Getting data from wheel rotation sensor
8. Getting a signal from steering wheel angle sensor
9. Calculation of productivity compressor
10. Control temperature and pressure of outdoor air
11. Reservoir pressure indicator
12. Car speed indicators
13. Indications of car level sensors
14. Calculation of the signal for the control valve
15. Receipt of the back bridge signal
16. Calculation of the required pressure in the main reservoir
17. Obtaining body level signal from left front, right in front
18. receipt of the back bridge signal
19. Obtaining data from pressure sensors
20. Calculation of car level
21. Getting data from level sensors
22. Information Signals (Management)
23. Data from a stop signal switch
24. Signal from the Comfort and Sport switch
25. Signal from the clearance regulator
26. Signal from contacts in the doors, trunk, from the remote control

Logic data processing

Incoming signals are processed in a logical component and converted to output signals.

1. Signals from body acceleration sensors ( B24 / 3., B24 / 8., B24 / 9.)
2. Vertical body acceleration is calculated using signals from body acceleration sensors.

Performance speed indicators, left and right:

1. The wheel speed indicators and data from the ESP control module are used.
2. Car speed
3. Longitudinal acceleration
4. Vehicle status. The difference between the moving and stationary vehicle is read.

Steering wheel sensor signal signal signal ( N49):

1. The lateral acceleration of the car is calculated using the signal from the steering wheel angle sensor and the wheel speed signal.

Signal from level sensors ( B22 / 8., B22 / 9., B22 / 3.):

1. Both front axle level sensor give 2 signals. Sensors are determined and transmitted between the wheel center and car body with the left and right side of the vehicle.
2. Rear axle sensors also give 2 signals. The sensor determines and transmits the distance between the wheel price and the body (with the difference that the average left and right wheels is calculated here).

Stop Sensor ( S9 / 1.):

1. When the driver presses the brake pedal, the signal is accepted with the kogical component and the rigidity of all racks switches to "hard", which reduces the "quilk" of the car's nose during braking.

Switching to "Comfort" and "Sport" switch ( N72/1s3):

1. switching the Pneumatic Speed \u200b\u200bMode "Comfort" and "Sport" informs the system of choices made by the driver between one comfortable and 2 sports hardware settings. The "Comfort" mode provides damping within the comfort range, as far as the driving style and road conditions are allowed. Mode "Sport 1" makes the suspension slightly tougher. "Sport 2" immediately adjusts the stiffness of shock absorbers to the maximum. The settings installed by the driver are saved until they are changed by the driver (even when the ignition is turned off).

Clearance adjustment signal from the switch ( N72/1s2):

1. The control module uses signals from the level adjustment switch to determine the driver's preferences relative to the car level:
2. Normal level
3. enlarged clearance

ADS II.

1. The control module uses the indicators of vertical, longitudinal and transverse acceleration of the body and the speed of movement to determine the optimal level of stiffness of the pneumos. 4 different stiffness levels can be installed for each of the wheels controlled by valves located on the racks. For example, rigidity is installed automatically for Sport 1 at speed velocity\u003e 160 km / h.
2. Control and adjustment of clearance
3. The control module uses the parameters from the car height switch selected by the driver and the velocity of the car to control the corresponding level through the control valves and sets the correct level of the vehicle according to the loading of the car.
4. Airmatic pneumatic suspension is equipped with a pressure tank to make the level changes as shorter as short as possible (for example, to align the car after loading). Compressed air from the tank is used only when it is necessary, so as not to download air into the tank too often. This happens, for example, if the height of the car drops below the critical level when the vehicle is loaded, or if the driver switched the system to the "Enlarged Road" position. Pressure from the tank is also used when the car is in a fixed state to minimize the noise. In the standard situation when the vehicle moves, the air in the pneumatic rack comes directly from the compressor.

Compressor management

The compressor is controlled through the relay. Since the compressor is not intended for continuous operation, the duration and phase of cooling are controlled to avoid the compressor overload.

Security chain

In the airmatic pneumatic suspension with ADS, the control module tracks all the important components of the system after switching on and during operation. The security circuit monitors the serviceability of the signals from the sensors, the serviceability of the control module and electrical components of the system. If a malfunction is detected, the system is disabled, and the corresponding message on the multifunction display of the instrument panel is displayed to warn the driver. The valve block is no longer controlled and the pneumatic resistant switches to the "Hard" mode (hard level for driving safety). In addition, the fault code is recorded in the control module. Clearance control is partially turned off depending on the type of malfunction - the system always seeks to maintain the selected vehicle level. In addition, the security circuit continuously controls the battery voltage. If the voltage drops below 10,5 V or exceeds 17.5 V, then the system is turned off until the voltage returns to the specified range.

Pressure supply components

42 - Airmatic Central Receiver
A9 / 1. - PNNEvatic airmatic compressor
Y36 / 6. - Clearance control valve block

In the usual mode, airmatic pneumatic suspension works with a pressure of 6 to 10 bar, depending on the load. The electrical compressor serves to supply pressure. In addition, the airmatic air suspension system has a receiver (42), which stores compressed air under pressure between 13 and 16 bar. The pressure in the system is maintained from the compressor when the car is moving, or from the receiver with a car, or a simple compressor.

Clien management

In the airmatic airmatic clearance of the front and rear axles is supported by the pneumatic suspension system. AirMatic supports the body at a constant level with the engine running, regardless of the load. For this, air from the air compressor comes to pneumatic resistant through the valve block to adjust the car level. The clearance of the car on the front axle is fixed, as well as on the back (with the difference that indicators and on the left and on the left are taken into account on the front axle, and on the back - only averaged indicator) with two level sensors, the data is sent to the Airmatic control module. The height of each of the pneumotes is controlled by the valve block and the safety valve on the compressor.

The main part of the compressor unit is the compressor itself and the electric motor. Also there are air dryer, filter, safety valves and valve block. The valve block is fixed by the same mounting panel slightly above the compressor and is powered by a high pressure pneumatic high pressure.

Drying air, as you understand, removes moisture from it. The safety valve is installed in the compressor setup (U1) required for the air removal when the car is lowering. Discharged air is carried out through the dryer back into the atmosphere. It also cleans the filter. The moisture separator is maintenance free. Condensate is discharged back to the atmosphere when discharged pressure.

Air filter

Busy, but it is quite difficult to get information about the functioning and planned maintenance of the air filter. In general, it is recommended to change the filter from time to time to prevent damage to the airmatic pneumatic suspension. But how much is it - who knows him. I would suggest the same as the salon filter. The filter can clog garbage and postpone salt from winter after our caring tracks that can block the filter. For W220, its number A2203200069, or WK32 / 6 or WK32 / 7 MANN. It is 10 euros in the original, and it will be replaced by 15-20 minutes. Photo new and used filter.

Replacing the compressor on the example of W220

1. Disconnect the battery.
2. Remove the scenery (right front part).
3. Disconnect high pressure pipes ( 1 ) and compressor ( A9 / 1.)
4. Disconnect the overpressure valve connector ( A9 / 1Y1.).
5. Disconnect the electrop connector from the compressor ( 3 ).
6. Pull air filter air intake hose ( 2 ) From the spar.
7. Unscrew the nuts fixing the compressor ( A9 / 1.).
8. Disconnect the compressor relay ( K40./7K) Only when installing a new compressor. With other works, do not disconnect the relay in order to avoid damage!
9. Install in reverse order.

Airmatic Pneumatic Pendant Components Overview

Airmatic pneumatic suspension valves ( Y36 / 6.)

Located above the compressor, the air suspension valve block (the part number A2203200258) is in the right front wing. The valve block controls the clearance of the car, measuring how much air is needed by each of the racks. It has an electromagnetic valve for each wheel ( y1., y2., y3. and y4.) To lift or lower the vehicle. Airmatic pneumatic suspension with a central collector ( u5.) It is connected to the valve block. System pressure sensor ( AT 7) Located on the end of the block.

For security reasons, only one valve can work at the same time. If the bridge asked too low, the pressure is supplied between the left and right valves alternately.

Lifting car

Valve u1., u2., u3. and u4. - respectively, in front of the left, on the right, to the right, from the left and back to the right, open as needed and compressed air from the centralhoresover or air compressor with the electric motor through the valve block ( Y36 / 6.) Heads pneumatic resistant. As soon as the required vehicle level is achieved on the front wheel, the corresponding valve ( y1. or y2.) Closes, another valve remains open until the car level also does not adjust on the other wheel. On the rear axis both valves ( u3. and u4.) Close when the vehicle reaches a specified level, mean between the right and left (remember, it was already already written that the height is read from each of the front sensors, and the average value is taken from the rear).

Lowering a car

Open valves of all pneumatic vehicles ( u1., u2., u3. and u4.) open, like the valve block ( Y36 / 6.). Together with them opens the pressure relief valve ( u1.) in the airmatic pneumatic suspension compressor ( A9 / 1.) And the compressed air goes through this valve. The valve on the pneumatic resistant remains open until the car reaches the necessary clearance.

Check for leaks

On the right side of the vehicle, remove the scenery to get open access to the compressor and the valve block.

Using the spray to detect leaks (or at a thin end of something like a soap solution), apply it on the line of connection 1, 2, 3, 4, 5, p on the valve block and wait 10-15 minutes after spraying. It will help to detect minor leaks. Heavy leaks are obvious immediately.

At times, the valve block fails when the valves cease to keep pressure, or they can not close due to the burr. Theoretically, some hundred years are taken to repair it, but how long this repair "will last" is like a lottery.

Pressure Sensor Airmatic Pressure Sensor (B7)

Located in the right front of the valve block. Measures the pressure in the system and is used by the control module for rechecking incoming data.

Pressure ( b.) is transmitted to the pressure sensor ( h.) with a metal protective diaphragm ( k.) and silicone oil ( i.). Electronics unit ( but), receives data on pressure in the form of analog voltage on the ECU, is inside the metal case ( D.).

Rack height sensor (B22 / 3, B22 / 8, B22 / 9)

B22 / 3 - Rear axle height sensor
B22 / 8 - Left Front Stand Height Sensor
B22 / 9 - Right Front Stand Height Sensor

These sensors define the height of the car on the front bridge and rear and transmit the obtained values \u200b\u200bto the Airmatic control module with ADS.

Sensor design: 2 Hall sensor in one case.

Determines the level of the vehicle using thrust from the upper transverse control levers to the left and right of the front axle. The sensor on the rear axle monitors the movement of the torsion and determines the average level of the vehicle. The sensor failure is detected by the control module when comparing signals from each of the sensors.

Central Airmatic Pneumatic Driving Receiver (42)

In essence, it is a metal cylinder that stores compressed air to use it, not straining the compressor once again. It is located on the left side, behind the bumper. (see photo)

Comfort / Sport Switch (N72 / 1S3)

This switch controls the adaptive damping system (ADS).

The switch with indicators is located at the top of the central console.

The ADS system automatically selects optimal damping for a particular road situation. Sports or comfortable mode tells her about your preferences at the moment.

The suspension setting is set in accordance with:

1. Your style driving
2. Road coating conditions
3. Your selection style of suspension, "Sport" or "Comfort", which you have chosen using the damper switch.

You can choose the following styles of the suspension:

"Comfort" - both indicator lamps ( 1 ) Disabled.
"Sport 1" - one indicator is on ( 1 ) On the control key.
"SPORT 2" - both indicators are burning ( 1 ) On the control key.

The selected suspension style is stored in memory even after you drown out the car.

Auto Level Control Switch (N72 / 1S2)

This switch controls the clearance of the car.

The following levels of car height settings can be selected when the car is in a stationary condition:

"Normal" - for ride on ordinary roads. Light indicator ( 1 ) switched off.
"Raised" - for riding an uneven road or when using anti-slip chains. Light indicator ( 1 ) Lit.

Select the "raised" setting option only when the current driving conditions require this. Otherwise, fuel consumption can increase and handling the car can also be broken.

The road clearance of the car increases or decreases in accordance with the selected level value and vehicle speed (these settings of the clearance are so small that you may not notice any changes):

1. With increasing speed, the ground clearance decreases by about 20 mm.
2. With a decrease in the speed, the traffic clearance rises again to the selected vehicle level.

The selected car clearance is stored in memory, even if the engine was muff and restarted. However, the raised vehicle will lower the clearance to a normal level when the speed of 120 km / h is exceeded, or if you will drive at the speed interval between 80 km / h and 120 km / h more than 5 minutes.

Airmatic Airmatic Pneumatic Control Module with ADS (N51)

Set the Airmatic Management Module: Perform all ADS and Airmatic control functions. The control unit itself is in the left fuse block.

Incoming data. The airmatic airmatic control module receives input signals from the CAN bus from the following components:

1. Module ESP Management Module

6. COMFORT / SPORT switch
7. Clearance switch
8. 3 body acceleration sensor
9. Two front axle height sensors
10. Rear axle height sensor
11. Pressure sensor Pneumatic suspension

Output functions. In the airlessness, the AIRMATIC input signals are processed by the control module, which based on this data gives outgoing signals for the following components:

1. Valve block
2. Central Receiver
3. Four valves ADS.
4. Multifunctional display
5. Indicators on level / mode switches
6. Air compressor

Pneumatic suspension racks (40, 41)

Airmatic pneumatic suspension stand takes all the functions of suspension, clearance control, clearance adjustment and stiffness.

40 - depreciation racks of the front axle. 41 - rear axle depreciation racks.

Pneumatic suspension stand design: A pneumatic pillow is integrated into a single-tube gas-filled shock absorber. Ads valve attached to pneumatic resistant.

40 - front
but - wall of the depreciation core

g. - Spring post buffer
h. - Air membrane
i. - Picky buffer
k. - valve residual pressure
l. - Aerial camera
m. - separation piston
n. - Protective Bellow
o. - Gas high pressure chamber

Function: The weight of the car is distributed between 4 pneumatic resistants that support clearance due to compressed air in the air chamber ( l.) that the rubber membrane is sealed below ( h.). Under dynamic loads during the movement of the membrane, being conjugate with air camsamers, it is rareled and rolled parallel to the axis of the core, thereby providing the necessary running of the rack. This whole zone is isolated from the outside world with a rubber boot ( n.) To protect against dirt.

Car clearance rises / lowers due to an increase in / reducing air pressure in the air chamber ( l.), which leads to the elongation / shortening of the rack ( 40 ). A pneumatic valve is mounted on top ( k.), which blocks the air in the counter of the control unit, or when the residual pressure level falls in the rack below 4-5 bar.

Arnott

Here is a controversial question. Arnott sells both new and recovered racks. Previously, they were only in the United States, but now there are in Europe, respectively, they became closer to us. But before you begin to google, where to buy Arnott racks, keep in mind:

1. Arnott argue that they use special seals made exclusively for them by Continental and they simply have eternal (well, at least, they say longer than the original). And in fact, Arnott provides a limited lifetime warranty for its products.
2. Arnott Restored racks are cheaper than new ones (and also you can hand over your old, decently earning, but ... Arnott only install a new air pillow and membrane - piston seals, a gas-filled shock absorber (bottom) no one touches. That is, yes, pneumatics works . Does the rack itself work and how much will it exist ??
3. There is also a "own" option from Arnott - but .. their racks do not support the ADS system (Active Dumping System). You connect them to the system, but the command is spelled in them .. to fool the computer. Thus, they simply give the control unit false information, as if ads works, although it is completely wrong. Sport 1 / Sport 2 modes will also be more unavailable.

Damping valve ( Y51., Y52., Y53, Y54)

His task is to adapt the stiffness of the shock absorbers to the style of driving and road conditions. The stiffness of the shock absorbers is adjustable in damping valves ( Y51., Y52., Y53, Y54). Each wheel has one damper valve, which is installed between the upper and lower supports of single-tube pneumatic shock absorbers. Each such valve (can be said, block) contains two electromagnetic valves ( U1., U2.), Which allows the block to switch to one of the 4 possible shock absorbers settings according to what command the valve block receives from the airmatic airmatic control module with ADS. Extremely short response time (millisecond) means that the optimal parameter of the damping effort is available almost immediately, if the sudden changes in the stiffness of the car's stroke are required - for example, during the maneuver evasion from the obstacle.

Design

Y51. - Front left damping valve
U1. - electromagnetic valve 1
U2. - electromagnetic valve 2
p. - Piston valve block

The damping valve (Y51, Y52, Y53, Y54) consists of a housing and two piston valves, which are located above the solenoids and together form an electromagnetic valve (U1, U2). Inside the system contains oil to absorb pressure drops and sudden loads.

ADS Pneumatic control module is used to get four different System settings:

Setup 1. For a comfortable ride with small priestly vibrations and low longitudinal and transverse accelerations. At the same time, both solenoid remain open, which allows the oil to flow freely, thus absorbing the pressure drops in pneumatic resistants.

Setting 2. The system goes into a more hard mode if the car is descended by some reasons, the solenoid valve U2 opens, and the solenoid valve U1 is closed.

Setting 3. Reverse action from setting 2

Setting 4. When moving to a sports mode, or registration with a system of sharp and strong longitudinal and transverse accelerations, to increase the safety of the car's movement of both electromagnetic valves Y1 and Y2 - close. All oil in the system is passed only under strong pressure. This setting can also be activated when the suspension fails and its further transition to emergency mode, which will be displayed on the corresponding message on the multifunction display.

Faults in airmatic pneumatic suspension

Let's start with the display. Sit (or go) You are in the car, suddenly hear a melodious bell and on the display ( A1R13) The message lights up: " Airmatic Visit Workshop!»Such a message on a white background means that in the system electrical failure.

It is in the case of an electric failure in the airmatic suspension with ADS you will see on the display " Airmatic Visit Workshop!", So, the culprit of this message is revealed and recorded in memory. Even if you restart the engine (and actually the system) and the message will disappear, and the suspension will work normally, I advise you to go to the station and the old one to read the errors to eliminate them.

It is important to remember that when a malfunction, the suspension passes into the emergency mode - the valve closes, the suspension becomes the most rigid, change the level of stiffness, as well as changing the clearance is no longer available as manually and automatically)

Hit # 2 - " Airmatic Stop, Car Tooo Low!"Yes, and red. Such a warning appears if the car clearance has become on the front axis more than 50 mm (60 mm USA), or on the rear axis more than 60 mm (70 mM USA) below normal level. The message will disappear if the level rises to 48 mm or 58 mm (58 mm or 68 mm in the US), respectively, below normal level. But the reason is better to reveal immediately, especially if it is not easy to leather because of very long downtime. How to get to a hundred - see below.

If in the process of driving suddenly you saw the lack of "Airmatic Stop, Car Tooo Low!", Stop immediately (try not to turn the wheels strongly) and inspect the car. If the level really fell below the permissible, you need to go to a hundred and look for the problem.

Do not drive with such a problem - this will entail:

1. The compressor will not work off and simply burns (it is possible to disable the compressor by driving a relay or fuse).
2. If the rack is low, the tire will rub the liner.
3. There is a risk of damaging other racks on one axis.

There is a temporary solution for the front racks you can use to get to the nearest workshop without the participation of the tow truck:

Step 1: Take wooden bars and cable ties

Step 2: With the help of a jack, raise the car

Step 3: Insert the wooden bar and secure it with cable ties

Step 4: Lower the car

It will be harsh, but slightly tougher than in the "Sport" mode - most importantly, it is up to a hundred reach, and even the wings with the hidels will be in place.

When message "Airmatic Visit Workshop!" White on the dashboard, which means that the fault is electrical character, without DAS it is not necessary - error codes are needed.

If an error of 1 valve is shown, for example, C1324-001 code - Fault in Component Y53Y1 (Left Rear Solenoid Valve 1) in Assembly Y53 (Left Rear Axle Damping Valve Unit) is most likely the solenoid valve is most likely, and if there are several errors Immediately - the high probability of bad contact, or similar options.

"Airmatic Stop, Car Tooo Low!" - Red on dashboard. Possible reasons

The compressor is dead - To test this hypothesis, boot the car and see if it works (you must hear the compressor in the front right wing area). If it does not work, check the fuse and relay. A faulty relay can lead to non-stop operation of the compressor, and he simply burns.

A leshetic stand - With a strong leakage, a characteristic hissing sound will be heard, with a weak - one can determine visually. It is very likely that the wheel on the other side (or the wheel on another axis on the same side) will also be significantly lower, but, as a rule, in a slightly lesser extent. Note that the same symptoms may also be observed when the line faults or valve block are malfunction, since the stand itself has a residual pressure valve that will block the air output from the rack only in case of pressure drops below 4-5 bar, which is not distinguished visually from perfectly Empty rack.

Line is not hermetic. It is possible that the line to the racks has cracks or microcracks. In the case of the front line of the line, which comes from the valve block to the racks, you can check the sprays (see above). However, it is so easy to get to the rear bridge through the interior of the car to the back bridge. The simplest solution is to start an alternative line bypass "native". Still does not work - approx, looking for further; It works - disassemble the salon and change the line. Either change in the valve block tubes from racks in places!

Valve block leakage. It is possible that the valve block is not correct and some of the valves does not close, then the pressure will be released back into the compressor and will be released from the system. Then the tube from the compressor to the valve block (side that enters the compressor lowers in water container and watch bubbles)

Central Receiver lost hermeticity. If the test indicates that the receiver can no longer hold pressure, check the line going to it before replacing it.

The level sensor is faulty. There are two clearance sensors for each of the front wheels and one for the rear axle. If the level sensor reports on incorrect height, the system will think that the car already has the necessary clearance and will not raise the vehicle. Information reported by sensors can be viewed using DAS. If the car rises, but then drops again, the height sensors are most likely not the reason for this.
