DSG 7 box with wet clutch. All about DSG boxes. The main breakdowns of mechatronics

DSG transmission is a family preselective gearboxes installed on Volkswagen AG concern cars.
The first DSG was launched in production in 2003, starting massively put on many models.
Since then, robotic checkpoints have repeatedly changed, all new modifications appeared.

“ Between themselves they differ in the design of the clutch, layout relative to the engine, and are also designed to work in tandem with motors having a different volume, torque and fuel type.

To date, there are the following types of DSG:

• DSG6-02E / 0D9 (DQ250) - the only one version DSG.With six steps.
  Equipped with a "wet" clutch, designed for anterior and all-wheel drive machines, with a maximum torque of up to 350 nm, and 1.4 - 3.2 liters;
• DSG7-0am / 0CW (DQ200) - The first generation of seven-step presextual.
  Dry adhesion. Designed for use with low-power DVS. Scope - front-wheel drive cars 1.2 -1.8 l, up to 250 nm;
• DSG7-0BT / 0BH (DQ500) - 7 steps, "wet" clutch.
  Put on powerful models with front or fully driveand transverse engine location. Adapted to transfer high torque (up to 600 nm);

DSG7-0B5 / 0CJ / 0CL / 0CK (DL501 / DL382) - also have seven gears, "wet" clutch, but developed specifically for cars with a longitudinal location of the motor.

To find out which type of gearbox is installed on your car, it is enough to connect a diagnostic device and read identification data or check by Vin-code In the appropriate directory.

Preselective box - a robot with two clutches is placed on many models released concern Volkswagen.At the same time, you can meet as an earlier version of the DSG-6 and DSG-7.

As practice shows to maximize the DSG service life, it is necessary to consider certain nuances during the operation of the PPC of this type. In this article we will look at how to properly use such a gearbox.

Read in this article

How to use DSG box

Let's start with the fact that DSG provides excellent acceleration dynamics and fuel efficiency inherent, as well as comfort. As a result, the preselative robot has become one of the most promising types of PPC.

At the same time, even taking into account the similarity with the automatic transmission on the principle of operation, as well as with the manual transmission, the operation of the car with the DSG is somewhat different from the machine, mechanics and simple single-robots (AMT gearbox).

Moreover, some nuances arise even depending on which type DSG is installed on a specific car model. For example, the DSG-6 box is "wet" (operating in the oil bath), while DSG-7 is "dry".

• In this case, the clutch discs, both in the first and in the second case west, and in the case of the DSG-7, it happens faster. This means that aggressive ride style, sharp accelerations from space, slip, etc. For DSG-6 are still allowed, but this cannot be said about DSG-7.

The fact is that the grip in the oily bath is more protected from wear and overheating than its "dry" analog. Also, DSG-6 was originally designed for a larger torque (about 350 nm), while the version of 7-steps "digested" is not more than 250 nm.

In practice, this means that harsh exploration will quickly bring DSG-7 in order. Cases should be mentioned when such a gearbox did not care more than 50-70 thousand km. Since the purchase and required expensive repairs.

• It is important to understand how to use DSG in traffic jam and operate the machine with this box within the city. First of all, in order to save fuel, the DSG in automatic mode usually quickly switches from the first to the second transmission. At the same time, if the driver is on the brake or not accelerates, the transition to the first speed again.

It turns out, with such a ride "jerks" occurs accelerated wear boxes and clutches, clutch overheats, etc. To avoid this, optimally switch to manual control using a semi-automatic mode of the box. If simply, the driver independently includes the first gear and does not switch to the second, if this situation has developed on the road.

• More in the list of rules that can increase the DSG resource, you should select the need to actively press the brake pedal when switching modes. In the event that the brake is not completely squeezed, the DSG does not fully open the clutch discs, thereby increasing wear.

Also, the transition rule to the "neutral" when stopped, relevant for "one-piece" robots, to a lesser extent affects the DSG. In other words, switch to N on traffic lights and during downtime to 60 seconds. No need, since frequent switching only increase wear. Moreover, with a fully press brake, the box itself opens the clutch.

You need to know that the DSG box (especially 7-step) is "afraid" slipping even more than automatic transmission. This means that to stop in the mud, on ice, when starting from place in manual mode, etc. prohibited.

Also, when setting in Parking regime, you need to use parking brakeTo extend the service life of the limiter (blocking mechanism), which prevents the car rollback. Switching between modes must be smooth, with a slight delay of about 1 second. During this time, the electronics will fully manage to "fit."

• It should be added that the car with DSG should not be overloaded towing the trailer or other transport, as well as transportation of various goods in the car itself. In practice, initially heavy machine with DSG-7 (for example, Skoda Superb.) About two tons can be weighed with a full cabin of passengers and additional cargo. Taking into account the fact that the box is not designed for heavy loads, such a robot may unexpectedly fail.

As for the DSG-6, this PPC is more worn and installed in a pair with powerful engines. However, this does not mean that the machine with such a transmission can be constantly used as a tug.

First of all, the DSG box needs maintenance, and more often than manual transmission. For example, in DSG-6, the clutch works in oil, the volume of lubricating fluid itself is quite large.

For this reason, the oil change in the DSG should be made every 60 thousand km. Run. In parallel, the gearbox filter changes. At the same time, without proper experience and equipment it is better to refuse self-substitution In the conditions of the garage.

We also add that if the machine with DSG is stuck in dirt or snow, you need to refrain from intensive attempts to go to the star. It is better to translate the box to N mode and use a third-party help, that is, pull out or pour out the car.

If there was a need for DSG, you need to adhere to the rules and recommendations, towing the machine with permitted speed and only for short distances. Information is usually contained in the manual.

That in the end

As can be seen, the operation of DSG quite strongly resembles the use of a classic hydromechanical automaton of automatic transmission. At the same time there are differences. For example, DSG allows you to switch from mode D to R without a small delay in N. However, it concerns the slip, the robotic transmission to them is most sensitive.

It should also be borne in mind that a robot with two clutches is a rather complicated unit in terms of construction. In this comparison with other types of transmission repair dsg. Often it turns out not only costly, but also problematic. The reason is not every car service capable of repairing DSG qualitatively.

As a result, we note that even taking into account all the difficulties and potential problems, the DSG box is still the most preferred option when choosing a new car.

Also, the manufacturer of VAG is constantly finalizing the design, makes changes to the PPC operation algorithms, improves firmware electronic block etc. As a result, you can count on improving reliability and a sufficiently long service life of the gearbox.

Perhaps the most famous type of modern gearboxes is a preselective robotic gearbox with two clutches - DSG. The most time is the box installed on cars of the concern VAG. The article will give answers to many who arise from motorists questions about this checkpoint will tell about the advantages and disadvantages of the box. The article will contain real as positive and negative feedback Car owners with DSG box.

A bit of history

DSG abbreviation is nothing more than doppelkupplungsgetriebe (it.) Or Dual SHIFT Gearbox (eng.). In Russian-speaking forums and communities of VAG car owners, you can meet such a decoding of DSG: two clips per year. :))) Next will be clear why some decipher this way.

The DGS box at the moment has different structures that are very different from each other. The first version of the box was released at the end of 2002. The box had six gears, the clutch in it was wet, kept the box torque up to 350 nm and was called DQ250.

In 2008, a lightweight and economical version of the DSG - DQ200 was published on the market. The seven-step box, the grip in it is dry type, but the box no longer pulls the big torque, it is limited to 250 nm.

The first and second option of the Boxes Concern VAG was developed with LUK and Borg Warner. In the fall of 2009, VAG developed and released a seven-step transmission with double clutch Already on their own. The box was called DQ500, kept torque up to 600 nm and thanks to which it could be used already on commercial machinery. Another modification of the DSG family can account with DL501 or S-Tronic, which is also calculated for a torque up to 600 nm and is installed mainly on Audi, but only on cars with a longitudinal location of the engine. This is a joint development of Audi and Borg Warner 2008.

"I own the sixth Passat with DSG, I can immediately say that the car is cool. I go on it for more than ten years, and I think that the box is just unnecessary here, although to be honest, those configuration of the trade winds that are sold from us, are not worthwhile They are asked for. On the DSG boxes I want to add that during the time they began to install them, the manufacturer significantly improved it. And if someone has problems with DSG, then this does not mean that they will be each. Also, already The Japanese use a robotic gearbox - Nissan and Toyota. My parents Camri has been with a robot for more than five years, and he enjoys a car every day. For five years there are no problems. "

Principle of action DSG.

In essence, DGS - mechanical PPCBut the gearbox itself occurs in it with a robot and without loss of power, and not as in conventional mechanics. In the manual transmission, the power is lost at the time of the squeezed clutch, and it is clear that at the time of the turning point of the torque from the wheels, the fuel combines the fuel. In general, the use of DSH should add a car dynamics and efficiency.

"I have two cars. On the same seven-step DSG, in the second - six. I like it very much how the DSG works. But it is worth saying that it is necessary to get used to it. The box is adaptive, which means it is adjusted to your ride mode. Can work and sharply And smoothly, it is not necessary to think that this is a malfunction. The box needs time to adapt. I like such boxes than ordinary automatic transmission. Already rolled more than 50 thousand. No problem problems. "

The main difference between DSG from any gearbox is the presence of two clips. But, in fact, still lying. Boxes are also two! And they are so integrated into one common case, which is not striking. And if the car uses two gearbox, the primary shaft can not be alone. So there are trees two, and everyone has its clutch. Now it is clear why you need a two-mask flywheel in DSG.

One shaft is equipped with gears for odd and rear gear, and the second, respectively, for even. After moving the car on the first transmission, the DSG has already turned on the second, and keeps it ready. And when the car needs to go to the next gear, the adhesion of the first shaft opens, and the second clutch quickly picks up the moment without loss of power and so on.

"I bought a Passat 1.8 TSI with 7-DSG. I bought a new one in the cabin. Already passed 30 thousand, there is no break. I want to note the amazing handling of the machine, which allows it to make it easy to maneuver on the road, including in traffic jams. With a set of velocity, the steering wheel becomes harder that gives additional control over the machine. Although the car is not racing, but periodically love to burn over the ring. True, when you enter the turns at speeds, more than 100 km / h there is a feeling that he blows the back axis. So it was in my old nine, But there I yourself overestimated the ass. I will try to change the rubber, maybe this is because of it so demolitions. But as for the box itself, the car accelerates just gorgeous, dynamics - at height. up to weave - 9 seconds. In the D mode, the box switches The transmissions, as if seeds snaps, still double grip allows you to keep two speeds included at the same time. If you translate the box into a sports mode, and to sneaker to the floor, then up to 190 km / h you can get oh how fast. Personally, you can get sick B 210 km / h. In short, I have no complaints about the box. Works great."

The inclusion of the gear DSG occurs by conventional clutches of synchronizers, and the plugs are driven by hydraulic cylinders, with the help of hydraulics, the clutch is turned on and off. He directs all these processes that the most notorious "mechatronics", which contains in its module the main electronics and the electro-hydraulic of this checkpoint.

The shaft of the even gear of this checkpoint is hollow. In the assembled form inside it is the shaft of odd gear. Such a cunning was able to accommodate two MCPs in one case.

DSG reliability

Unlike classical automatic transmission, which neither clutch, nor a powerful flywheel, DSH uses these components. Moreover, the flywheel needs a two-mask and a good margin of strength, like a manual transmission (minimum 150 thousand km of run). But in practice, the flywheel at DSG may fail much faster.

"The seventh DSG is a real selo. I blurried not only the mechatronics, but also a grip. Moreover, judging by the forums - I'm not alone. The familiar master said that for him every month I consistently arrived at least one Audi, Volkswagen or Toyota with problems of the same box - then mechatron, then clutch. And always this repair is simply unrealistic money. Yes, what to say - thug on the request "Mechatronics for DSG" and everything will become understandable. But with DSG-6 things are different. Earlier I was a golf with sixth DSG, which did not prove it with anything bad, because I was not afraid to buy a car with such a box, but seven, what I regretted. With golf for 5 years there was no problems. I will not have a board, those who want to buy a car - Do not buy cars with 7-Dsg. "

The wet type of clutch in DSG is better cooled, which is why it has a greater resource - about 300 thousand km. But the resource of dry clutch is declared 150-200 thousand km. But again, dry clutch in practice does not consume so much, and the reason lies in the box control system - mechatronics. In it, before running 100 thousand, damage to the electromagnetic valves usually occurs. But the thing is that the mechatronics is located on the top of the PPC block, which is heated as much as the box itself. To understand that the box is heated very much, it suffices to say that its design is not for the presence of a water-oil separator (heat exchanger). You can imagine what temperature drops are experiencing a mechatronics by car, which first spent the night on the street in the twenty-graduce frost, and then drove on the highway with decent speedOr even worse - started "crawling" in traffic.

As you know, demand gives rise to a proposal, and today there are many services that offer Mechatronics repairs. The official dealer does not do this, and offers full replacement CAT. It is worth noting that DSG in the usual garage will not be able to repair - special tools are needed, which ensure compliance with the accumulation of up to five microns.

Consider options DSG boxes

DQ 250 (DSG-6)

The box has six gears, can withstand torque up to 350 nm. Clutch at a wet box. Often the box is indicated as DSG-6. The box needs regular maintenance every 60 thousand km, which consists in replacing the oil and filter. If the oil is not changed, the mechatronics fails quickly.

This is the first generation of DGS boxes, which was used on VW cars: Golf 5 1.4 FSI and diesel 1.9 and 2.0 TDI ; Touran, Passat B6 with diesel units 2.0 TDI ; Skoda Octavia second generation with two-liter turbocharged diesel ; and seat leon with the same diesel aggregate. The box is not devoid of flaws, but over the past more than 10 years, many car owners managed to eliminate. DSG-6 has proven itself well.

DQ 200 (DSG-7)

Seven-step KPP designed for torque up to 250 nm. The box has a dry clutch, the manufacturer does not provide for the regulatory maintenance DQ200. Many car services are still advised to perform a regular replacement of the liquid in the oil circuits of the PPC. Most complaints from car owners on this box.

Since the box is not designed for a serious torque, it was installed on the mediterranean models 1.4, 1.6, a maximum of 1.8-liter engines, mainly with a turbine.




Box had constructive featuresFor example, the pump of its hydraulic system was connected at a request from an electric motor. This allowed the car to be more economical at low loads.

It would seem - excellent gearbox, light, economical, dry clutch from LUK is designed for 300 thousand km of mileage, it is not necessary to serve the box. Ride and rejoice! But ... these "but" will be written just below. In the meantime, you will continue to acquaint with the types of boxes.

DQ 500 and DL 501

Serious "korzas" for a serious moment - 600 nm. Installed mainly on expensive and powerful audios, VW minibuses, although it is found on two-liter turbocharged Tiguen . The grip is wet, gear - seven.




Typical problems DSG.

But now consider those "but", about which mentioned above. It all started with many with a small grincling, clanging, shocks sometimes when driving irregularities, sometimes on an even place with a measured ride. After turning to the dealer, he conducted the diagnostics of the CAT, which did not detect any errors, and in the absence of vibration and jerks, the client was usually refused to the client. VW urged to consider such "small" malfunctions with a normal phenomenon.

But even more was the number of complaints about pushing, vibration and tremors when switching transmissions with 1st to 2nd and simply when driving at low speed. If the problem is not treated, then over time it has grown: the strength of vibrations increased, the clutch began to slip. Could even disappear even or odd programs. Translations were returned after replacing clutch disks.

If the hydraulics of the box overheated, the transmissions begin to be turned on by jerks, as if hinting with the driver that they say, "change the intensity of switching, moving evenly." Such problems most often arise in traffic jams, where the ride manner is appropriate: moved, stopped, moved, stopped. With such a ride, the hydraulics is heated in the box strong enough, and the clutch is experiencing an increased load.

Some motorists complained that the box did not want to include the transferences. No. And it could happen in motion. Sometimes the restart of the car solved the problem if it did not help - it was necessary to repair or change the mechatronics.

"I go to Volzz Passat 6 with an automatic DSG. Excellent Everything was all for a long time, there are no complaints to the box, but as soon as I decided to sell the car, it began. Flying gearbox, and what is strange - on a flat place. Drived about 50 km / h, and all - The box was simply refused to switch the transfer. I had to cause a tow truck. For a hundred sentenced some kind of "Mechatronics". According to experts, he burned down due to the fact that it somehow got the oil. For the repair, they requested a little more than 100,000 Russian rubles. I just went nuts, but what was done. After that, I was talking to other owners of such cars. Everything is aware of such a problem, and it is often found. And I didn't know, and I did not have time to sell the car. Conclusion - the box needs a serious refinement. . Early still put it on cars. "

Next, the manufacturer discovered an unpleasant feature. synthetic oilused in DSG: In a warm environment, the oil began to interact with copper parts of the block, sometimes causing a short circuit. After that, the clutch ceased to turn on. Many owners rushed to change the oil on the mineral water, but, alas, I could not solve a fully problem, and such an oil does not meet the climatic Russian conditions.

Some car owners changed who is mechatronics, and who is entirely guaranteed. But it did not give a blanche card for the future - there were many cases when the same problems arose already on the stubborn boxes. The opening of the "dead" boxes revealed the presence of chips, which was liked, most likely due to improper operation of the control unit of the PPC.

Answers to frequently asked questions on DSG can be found


It is worth remembering, 7-DSG are actually unrepretentious. The repair of the box on third-party services is carried out at their own risk and without any guarantees. Even the oil in it in the conditions of the garage is practically unrealistic.

How to determine that your DSG has failed mechatronics:

The box switched to N mode and on dashboard You see the "PRNDS" indication;

The first transmission is now turned on very rigidly;

In the same way, the switching between the transmissions 1-2-3 is tight, sometimes clear clicks are heard at these moments;

When braking on the second gear, vibration is clearly felt;

When revolutions below 2 thousand, the feeling appeared that the thrust was disappeared.

In many negarters, it is worth thinking about the feasibility of purchase new box - Its cost can be equal to the cost of the average car in the secondary market.

What is the percentage of DSG breakdown? And no one would say anything. Official statistics are: in the warranty period, approaching the replacement of DSG approximately 5% of car owners. As far as this is true - unknown. One thing is known - if you have such a box, then it does not mean that it will absolutely fail. Most cars are still driving without problems with DSG.

"I can say for sure - if you do not know how to use DSG, then you don't need to lie. I have a Passat with DSG-6, I have been going on it for almost 7 years. No problems do not give the box. I change the oil during and that's the first time. When replacing the oil, I thought - pour the original, or to take some substitute for cheaper. I did not take risks and flooded the original. In the box, when the oil was replaced, I saw dirt and chips. The car by that time began to start and twitch a little. I thought that if the oil was not helped, It is necessary to go to the service. After replacing the oil, all the problems disappeared! Everything began to work as on a new car. But my kum decided to save and bought a non-original oil. The week chased, and the car became a stake. Make it start, but the transmission to switch the box already Could not. In the end, I got to replace the gearbox at the dealer. In addition to the fact that the dubbed bought a bunch, I had to wait for a month. So do not leut into the box of any g. "

Situating complaints of car owners with DSH, you can conclude: the DSG box does not tolerate the ride mode permanent work Clutch and frequent gear shifts. A typical example is a permanent ride in traffic jams. Such a ride overheats the box, wear off the clutch and breaks mechatronics. But, for driving in traffic, it is preferable to names such or a classic automatic box. It is terribly uncomfortable to pull the "Kochergu" in the traffic jam, so they buy residents of metropolis cars with DSG, for a comfortable ride. But it was not there...

Next, it is important to keep in mind that DSG is not for "riders"! She does not like sports driving, and receiving the engine promotion with a squeezed brake pedal for further sharp breakdown can kill DSG with dry clutch literally from one such start.

In general, the problems of DSG lies in complex technologies, and well done Volkswagen, which develops and improves the topic of fast and simultaneously smooth driving, being, in fact, the leader in this area. Yes, and environmentalists have a certain pressure on these developments - after all, the usual automatic transmission consumes more fuel, and therefore emissions into the atmosphere of such cars more.

So still - buy or not a car with a DSG box? Why not? But it is advisable to take a car from VW not older than 2012 or with a box DQ250. After all, you need to understand that there are problems from other machines and with another type of gearbox. What is worth, for example, the French automatic machine DP0 / DP2. Yes, DSG has more percentage of failure, but it is not equal to one hundred. Yes, and from exploitation and timely service, much depends. I would like to believe that many typical shoals corrected the latest modernization of this type of gearbox, and now problems with boxes will be much smaller. But if you are still a true connoisseur of durability and reliability, then you don't need such a box, brother. " Look for anything at the present simple - simple manual transmission, simple car pack, smaller frills and electronics in the car, because than easier mechanismThe smaller the probability of breakdowns. This rule concerns not only cars.

But the author of the article still hopes that problems with new DSG remained in the past, and if they were not left - then a couple of years, and VAG "re-" this type gearboxes to optimal state. And the remaining manufacturers will also start equipping their cars with such a gearbox. After all, still damn nice to ride the car with DSG!

To collect information about the operation of the DSG box, its breakdowns and faults, leave your feedback and share your experience. Descendants will be grateful to you.

Today we will look at what is an automatic DSG box (DSG).

It should be noted that this system with DSG invented and actively introduces a VAG concern (Volkswagen). Box DSG What is it?

In the article we will touch the device of this transmission and the principle of work. We will also consider whether it is being afraid of it and in what cases the choice of a robotic box is the perfect option.

Translated from English DSG ( Direct Shift. Gearbox) means a direct shift gearbox.

Before proceeding to the device description, clarity should be made. Types of robotic boxes a lot and different manufacturers they are called differently (for example, ford PowerShift.). Although it is no secret that the device of all similar, only nuances differ.

To understand the principle of operation of the DSG box (DSG), you must submit two mechanical boxes connected together. In such a transmission, the following components are installed:

• two clutches;
• two sets of incoming and leaving shafts and gears;
• mechatronics.

Not in vain above was said about two gearboxes, because in a robotic DSG box, two transmissions are included at the same time. But one grip is open. Therefore, the second transmission is in waiting mode.

When there is a need to enable the next transmission, the open clutch is closed, and the fact that it is turned on to be disconnected. At the same time, there is a continuous transmission of torque on the wheels.

All process management is managed by mechatronics. This is a set of out hydraulic drives, electric motors and microprocessor control system.

It keeps track of numerous sensors What gear should be included next and prepares it on the second shaft.

The benefit of the transfer goes in turn, on one shaft are even, and on another odd.
It should be noted that the DSG box is two types:

1. "Wet" six-speed;
2. "Dry" seven-step.

Scheme 6-speed robotic gearbox with (wet) clutch

Significant differences between the types of boxes are a bit, but they are. Just the first company VAG created a seven-step box. It was economical, fast, technological, but the clutch was dry, and because of this, the resource was extremely low.

Scheme 7-speed robotic gearbox with (dry) clutch

Often such DSG boxes broke with mileage up to 80 thousand km. This indicator of the resource for our country, as in Europe completely different operating conditions (more gentle).

The six-speed DSG box can be viewed as the next stage of the development of robotic boxes. In it, "dry" clutch is replaced by "wet", with oil supply with a special electric pump.

This step allowed significantly increased the resource of robotic boxes, somewhere by 30-40%. Also, this decision made it possible to raise the torque power digestible box with 250 nm to 350 nm. What caused the possibility of installing such boxes on Class cars (WV Passat, Skoda Superb).

In addition, the concern always works on improving all the characteristics, including reliability. Robotic gearboxes have already passed several generations of their production and at the moment their resource is approaching 150-170 thousand km.

Automatic Box DSG (DSG) - promising development

You may ask, why does the manufacturer make such unreliable gearboxes, besides expensive in repair?

And the answer is simple, such a type of transmission is the following steps in the development of transmissions on cars and in terms of its consumer properties on the head above all other solutions.

DSG allows you to save fuel better than other boxes, fully implements the entire torque of the engine, while the hydrotransformator box, on the contrary, eats 10-15% power.

Also, the advantages should be attributed to switching transmissions without breaking the power, which adds. And there is such a transmission only one disadvantage - reliability.

But you can put up with this, as the manufacturer gives the manufacturer to 100 TIS to buyers. km on all major nodes and DSG including. Knowing it, you can safely ride until the end of the warranty period without fear for your car.

How to extend the life of a robotic gearbox

1. It is necessary to include forcibly the first speed when driving in a traffic jam, which does not allow the gearbox to constantly throw between the first and second speed. It seemed like a simple movement, we significantly saved the clutch resource.
2. Second - include neutral mode when long parking In one place, for example, in the same traffic jam.
3. Well, finally, general advice. Try to move smooth, without sharp starts and slip. Do not forget to change the box into the oil, because it is thermally loaded and decay products begin to appear more often than mechanical. Although the manufacturer declares that the box is maintenanceable, it is still, after 60-70 TIS. km. Services recommend changing oil.

Summing up the article can be said that the DSG box is a modern economical unit that has not yet cured from childhood diseases. Therefore, recommend only to purchase. new car on guarantee.

Or buying a used car with such a transmission to lay in the budget amount for repairs, since it is impossible to accurately diagnose it. In addition, do not forget about the operating tips for a confident and prolonged ride.

Moreover, in the VAG concern there are also engines, which, like DSG, can create a lot of problems. But this is already the topic of another article, but for now I tell you to new interesting materials.

The DSG transmission combines a mechanical and automatic transmission. The bottom line is that the driver switches manually manually, and the process itself is performed by means of electronics and automatic mechanisms. For the first time this gearbox was launched in mass production company Volkswagen. AG.

Design DSG.

Automatic DSG is arranged as follows. On the basis of one axis there are two intermediate shafts, one of which is hollow and passes through itself the second. The gears and the outer shaft are connected to the two secondary shafts on which the pairs of gear of all odd and rear gears are installed. The transmission is turned on using a synchronizer and coupling. The entire process is controlled electronically by means of a hydraulic amplifier.

From a technical point of view dSG box is a more advanced MCP option.It presents many of its components: primary and secondary shaft, clutch, synchronizers. In all other, the differences begins. Robotic transmission Ensures the driver from the need to squeeze the clutch pedal mechanically. This work is performed by electronics, which, taking into account the selected mode, independently connects transmissions.

DSG gearbox features

DSG has five shafts, which, in combination with gears and two clutches, form a double-circuit mechanism that provides torque transmission. Thereby cars on which this KP is installed, the speed is gaining faster, rather than cars with mechanical transmission. Switching the speeds is no different from the modern ACP, so the DSG has long been used on sports cars, where the speed is of great importance. In addition, this transmission provides for the possibility of switching gear manually - using the Tiptronic system or manipulator on the steering wheel.

Two multi-disc clutches provide torque transmission. When one of them is closed and one transmission works, the gears are already in engagement, you just need to close the second clutch. Upon receipt of the command from the control panel, the mechanism instantly turns one clutch and closes the second, simultaneously actuating another transmission.

Advantages of the DSG box

Primarily, transmission makes the time of overclocking the minimum and saves fuelthat is very relevant today. When operating the switching is invisible, as a result, the feeling appears that the machine is riding only on one transmission. In the cabin there are only two pedals - gas and brake. It's enough. Transmission selector is the same as automatic boxes Transmissions. And if you do not like something, you can always control the transmission manually, translating the lever down or up. The use of a robotic box reduces fuel consumption. Car enthusiasts note that savings reaches twenty percent in comparison with similar models equipped with automatic transmission.

The video shows the assembly of the DSG gearbox:

Undoubted plus - switching speed and overclocking dynamics. Cars on which such a box is installed, they accelerate faster than fellow workers equipped with mechanics. At the same time, power remains at the same level. DSG - Aggregate Reliable and provided properly operation Long stay long. But the repair of this KP is impossible. Although it is quite possible, this problem will be solved in the near future.

Disadvantages of DSG.

Among the minuses of transmission can be noted as follows:

1. , equipped with such a CP, significantly increases due to the technical complexity of the equipment.
2. In case of acceleration and switching, there are minor machine jerks.
3. Sharp acceleration causes small delays - the box does not have time to jump through the transmission.
4. Control blocks are quickly wearing, resulting in the need for premature repair.
