How to remove the play steering. Steering Repair - Diagnostics, Elimination of the Steering Wheel Handle and Replacing the Steering Wheel Sensor. Steering diagnostics - where to rotate the steering wheel for repair

the main / miscellanea

Many domestic motorists, including owners of the VAZ "seven", are familiar with such a steering defect, which is the backlash wheels. Especially clearly it is felt when the car is moving at a high speed in a straight line. A generally accepted way to identify symptoms of this malfunction is a sharp turn of the steering wheel. In the event that it (rotation) is accompanied by a knock, there is a backlash steering wheel "VAZ 2107".

The article offered to your attention will be discussed about the sequence of actions performed in the process of checking the technical condition of the steering mechanism, as well as in the implementation of the adjustment activities.

Control of the size of the free stroke (backlash) steering wheel

I. Preparatory activities When checking the free stroke of the steering wheel include installation vehicle On the overpass (observation pit), bringing tire pressure to the level recommended by the manufacturer and selection of the assistant.

II. Performing the steering wheel to go to the right, we determine the value of the angle of rotation until the rotation of the wheels. It should not exceed (in each direction) 50. In addition, if the force when turning is more than 20 kgf, or 196 N, is a sign of a violation of the normal gearing elements of the steering gear (hereinafter referred to as RM).

Adjusting the engagement of the steering gear elements:

I. Install the vehicle wheels to a position corresponding to a straightforward movement.

II. Clean the crankcase lid PM from dirt and leasing leases.

III. With a screwdriver, we remove the cap protecting the adjusting screw.

IV. Through the key to "19" weaken the adjusting screw fixation nut.
V. The assistant performs energetic swing steering wheels to the right and left.
Vi. By rotating the adjusting screw, correct the size of the free stroke (reducing the effort attached to the steering wheel) by increasing (reducing) the closuit of the engagement. Rotation clockwise provides it (gap) decrease, against - increase.

VII. By direct screwdriver fix the adjusting screw, while at the same time tightening the nut. Install the protective cap.
VIII. We check the force of rotation with the extreme left (right) position of the front wheels, which allows us to find out the true degree of wear of the reducer worm. If necessary, adjust the engagement of the elements of the RM gearbox in one of the extreme positions of the wheels.
IX. The implementation of the above measures provides the icon of the steering wheel "VAZ 2107" within the borders specified by the manufacturer.

Video - how to eliminate the backlash steering

4 years ago

Welcome!
Steering Wheel Player - Is Satisfied frequent problem Almost all cars in the particular car "classic" family. The backlash can occur for different reasons, ranging from a banal hitting a hammer and ending with a malfunction in the system of steering itself, so to remove the backlash you will have to make an effort that in future you will appreciate.

Note!
To adjust the backup you will need to be stock: scolding and also a wrench on "17"!

Summary:

Why can the backlash?
In fact, it arises for various reasons, some of them were described above. But when the backup occurs, this may be guilty of: a weakened or strongly worn fastening of the steering mechanism, as well as the pendulum lever and the steering themselves.

Note!
Before sining on all these items of the steering mechanism, it is first recommended to check and, if possible, fix the increased gap that can be found in the engagement of the roller with the worm of the steering mechanism - we will take this adjustment!

How to adjust the backlash, is it a free course of the steering wheel on the VAZ 2101-VAZ 2107?

Note!
Work is better to do with the assistant, as it is much easier and more convenient!

1) At the beginning, remove the protective cap that closes the adjusting screw of the column.

2) Then loosen the adjusting screw nut (indicated by the red arrow) with the "17" wrench. The nut must be loosen before it was possible to lift the washer located under this nut (indicated by the blue arrow).

Following when the nut will be relaxed, ask your assistant to get behind the wheel in your car and sharply turn the steering wheel several times in different directions, you will screw the adjusting screw at this time, which is indicated by the green arrow.

Note!
Do it before the retailer does not become within the normal range. And also do not tighten the hardly adjusting screw painfully, and otherwise because of this, the steering wheel can start very hard to spin!

Note!
After the operations done, check the free step of the steering wheel in the event that the steering wheel is dry hard, then just loosen the adjusting screw loosening for this nut. In the event that, after completing the work, the handlebar remained the same or moved but not significantly, and if the turning of the steering wheel is accompanied by a creak and clicks, then in this case, repaired in the auto repair shop or replace the steering mechanism on the new one!

The steering mechanism thing is very thin and therefore it is not recommended to repair it yourself, because with an incorrect assembly, the mechanism can jam on the road in connection with which the car will stop responding on the movement of the steering wheel!

Question?
And how do you regulate the free move from the steering wheel? (Answer write in the comments)

Additional video clip:
More detailed adjustment of the free stroke of the steering wheel, you can watch the video clove that is located just below:

The backlash is the term in mechanics that implies the presence of free stroke at the element mechanical system. It is a parameter for which one can judge the magnitude of the motion of the node mentioned above to obtain an answer from the other - managed node.

In other words, the size of the backlash is characterized as the magnitude of the rotation or offset of the controlled element, which does not lead to any changes in the object.

With reference to the car and the angle of rotation of the steering wheel, in which the car continues to move in the constant direction.

What is meant under the total handle of the steering wheel?

Another term requiring consideration - " summary Lenta" Under it implies a common angle, the countdown of which begins with the extreme position of the steering wheel on the one hand, when the turn begins, to the opposite position, when the car begins to move in the other direction.

To understand the principles of operation of the total backlash, it is important to understand the design and features of the management system. If we proceed from the technical component, the principle of operation of the backlash has the following form.

In the transmission of steering, there is a rod, which is fixed with a small gap in one or two millimeters.

This distance is necessary to protect the nodes of the engagement of the steering system from wear due to excessive friction.

The presence of a gap is a technological solution that allows you to keep the hook in the required position and do not touch the surface of the teeth.

For the driver, this parameter is the free step of the steering wheel, which allows you to get more accurately controlled by the car and feel at what point the direction of the vehicle movement changes.

In essence, this is the total distance that the steering wheel passes before the car goes to the left or right side.

Many mistakenly consider this phenomenon with negative and try to get rid of it. Do not do this, because the backlash player is the norm for each car. Another thing is that it should have a strictly defined value.

An interesting pattern is traced here - the larger dimensions have a car, the more high is the backlash.

In the process of measuring the total backlash, a number of conditions are observed:

The front wheels are located in a neutral position and stand on a solid (asphalt or concrete) surface.
Tires controlled wheels dry and clean.
Engine car is instituted. This is relevant if the operation of the steering wheel amplifier is tested.
Tension drive belt Pump power steering, as well as level working fluid Must meet the requirements approved by the manufacturer.

Checking the total backlash is performed by measuring the angle of rotation of the control wheel between the fixed positions of changing the movement into the left and right side.

To obtain accurate parameters, the measurement is made from two or more times.

What is the beginning of the rotation of the steering wheel?

In addition to the above, there is another term that you need to know - the start of the rotation of the controlled wheel.

Under this parameter hides an angle of rotation of the wheel by 0.06 degrees with an error of 0.01 degrees in the same side.

The measurement of the parameter is made when repulsted from the position of the straight movement.

Permissible Lufts in cars

The normative indicators of the total backlash are prescribed in traffic rules for different cars. In addition, this parameter should not exceed the numbers specified in the machine operation documentation.

If there are no special recommendations in the manufacturer's papers, the backlash should be as follows:

For passenger cars, as well as on their basis nodes of buses and trucks - 10;
For buses - 20;
For trucks -25.

For VAZ-2106, 2107, 2110, 21213 - 5;
For Gazelle 3302 - 20 (passenger variant) and 25 (cargo machine).

Causes of big backlash

An explanation of the increase in the backup may be changes in constructive features steering, as well as the destruction of their elements.

To the main reasons can be attributed:

If we speak as a whole, the backlash occurs when the chain is malfunction between the steering wheel and wheels.

To find out the reason, it is necessary to go through the entire chain and determine the "weak" places. The main thing is to make sure that we are talking about the increased free course, and not about other problems.

To other reasons, the play in the steering can be attributed:

Wearing or improper adjustment of the engagement "worm" and roller mechanism.
Wear axis or sleeves of pendulum lever.
Weakening of the fastener of the crankcase.

Signs of breakdown

As noted above, it must be diagnosed to effectively troubleshoot the fault. To do this, it is enough to know the signs of the backlash in the steering control.

The main symptoms include:

The appearance of the knock in the steering mechanism;
Increased vibrations during movement;
Creak when turning the wheels;
Deviation from a given trajectory with a direct position of the steering wheel.

When setting up the steering backlash, take into account the manufacturer's recommendations and rules of PDD.

The configured parameter should not exceed the upper limit, but also to undertake the indicator is also not worth it.

The steering wheel will be too low can lead to additional discomfort and deterioration by car.

At the same time, it is not necessary to ignore the appearance of a small backlash, because over time this parameter may increase, and then it will be more difficult to deal with the problem.

And it's inconvenient to manage the machine when you constantly "catch the road" and rotate the steering wheel in the same way.

Diagnosis of the problem and applied instruments

To determine whether the parameter corresponds to the norm, it is necessary to make a small check.

To accurately make sure that the problems can be used, you can use a special device - a luftomer.

With it, you can check the overall (total) backlash in the system.

One of the options of the device is to 524 m or Isl-M, which can be applied by conventional car owners and professional professionals.

With the help of a luftomer, it is possible to determine the amount of free stroke in just three minutes, including taking into account the installation and removal of the device.

Algorithm of actions in the diagnosis of steering backlash, the following:

Get the engine (it should work on idling);
Put the front wheels parallel to the longitudinal axis of the machine. At the same time, make sure the hydraulic amplifier;
Turn the steering wheel into one, and then to the other side. At this point, fix the moments when the front wheels begin to scroll in the desired direction. The distance that the steering wheel passes between these intervals is called the backlash (free move).

Such a check is considered excellent option For drivers who need accurate and fast information.

It does not matter how the problem was diagnosed. If the backlash player is greater than the norm, it must be eliminated.

How to eliminate malfunction: basic ways

To adjust steeringThis will require a standard set of tools that allow you to adjust the mount.

If manual measurement or device to 524 m showed an inappropriate result, it is worth doing the following:

Try adjusting the screws that enhance the cardan hinges. You can find these elements on the steering shaft.
Using the Hinker Adjustment Screw, place the required parameter.
Check the back of the back. If the free move remained above the norm, it is necessary to look for another reason.
Tighten the adjusting nut on the steering rake (if such is provided), it will eliminate the gaps between the gear plate and the leading gear, which may be the cause of the backup.

The next step in the adjustment can be setting steering hinges.

Make it in the conditions of the garage harder, because it will take a flight to fulfill work, looking Yama or lift.

With a high probability you will see that the hinges are damaged, and this indicates the need for screwing screws. In addition, it is worth stretching and steering traction.

If the methods described above cannot be eliminated, only one solution remains - to disassemble the steering mechanism and change the details failed.

In the absence of necessary experience and knowledge, you can refer to experienced specialists for a hundred.

An enlarged handle of the steering wheel VAZ 2107 is a fairly common problem, characteristic of the whole family of "Classics". In most cases, it is possible to eliminate the malfunction independently without resorting to a complex expensive repair. It is only important to correctly diagnose and localize the reasons for the backlash in the steering mechanism.

Checking the handle of the steering wheel VAZ 2107

Big Wood Red Rule 207 - Blurry Concept. Meanwhile, the allowable backlash rude has set standards. For "classics" it is 5 degrees. To check the backlash, a special device is used for a service station - a luftomer. At home, you can do without it. To do this, it will take a ruler, chalk (or wire) and a partner assistance.
Check the size of the backlash is performed as follows:

install the machine on a flat platform;
check the tire pressure, if necessary, roll them up;
put the steering wheel so that the wheels are directed parallel to the axis of the machine;

IMPORTANT: If the wheels are exactly, and the wheel of the wheel is disshived, it is possible to break the angles of the wheel setting, the presence of suspension and steering defects. You should adjust or repair steering and suspension.

place the line so that it will be left in dashboard, touched the top of the headlight light switch and, second end, wheel rim;
smoothly rotate the steering wheel until the partner monitors the position of the front wheels;
as soon as the wheels begin to shift, stop the rotation of the steering wheel;
make a chalk mark on the steering wheel opposite the ruler (or wrap the steering wheel with wire);
smoothly rotate the steering wheel in another direction until the partner notes that the wheels began to rotate;
apply a chalk to the steering wheel another mark or wrap it with a second piece of wire;
emerriate the distance between the labels on the wheel rid.

The laptop 5 degrees corresponds to a displacement of 17 mm with a diameter of the steering wheel 40 centimeters.

Causes of Handle Handlebar VAZ 2107

If you have noticed an unacceptable handhel of the Waz 2107, the reasons for it can be as follows:

the central nut of the steering wheel fastening on the axis is not tightened;
the nut fastening nut is weakened to the gearbox;
the worm gear of the steering mechanism is not adjusted;
worn the sleeves of the steering mechanism;
damaged steering thrusts or their tips are worn.

All listed problems require immediate interference. Otherwise, the steering mechanism can fail and the machine will lose control.

How to remove the backlash rudder on the VAZ 2107

Start work follows from checking tightening of the threaded connections of the steering mechanism and the state of the steering (tips). Cut thrust or worn steering tip hngers are subject to replacement. To do this, you will have to use the puller and a wrench to 22. Do not try to align traction or repair tips. For security reasons, these details should always be replaced by new ones.
Next, check the condition of the pendulum and adjustment worm gear.
Worn pendulum sleeves must be replaced with new ones. To do this, unscrew the steering thrust from it (the key to 22 and the puller is used) and remove the pendulum from the car, reloading the mounting bolts. Pendulum clamp in vice, remove the pin and unscrew the adjusting nut. When the nut is unscrewed, you can disassemble the pendulum and replace the worn sleeves with new ones. When assembling a pendulum, it is necessary to spin the adjusting nut so that its bumps rotate with an effort of 1-2 kilograms.
If all parts are replaced or working, and threaded connections Tightened, adjusting the hood of the steering wheel VAZ 2107 is carried out by adjusting the steering gearbox. To do this, you will need the key to 19 and a powerful slotted screwdriver. Adjustment is performed as follows:

Thus, you can adjust the play of the steering wheel of the VAZ 2107 in accordance with the boundaries installed by the manufacturer.

A modern car is a complex set of nodes and mechanisms, which, unfortunately, are susceptible to wear. The steering wheel control system is particularly rapidly raised due to the fact that most of its nodes work in extreme conditions, malfunction occurs as the backlash backlash. First of all, it should be borne in mind that her elimination should not be postponed in a long box, as it is about damage due to the danger to life not only the driver and passengers, but also other participants road. And so, consider the reasons due to which this malfunction arises, and also learn how to remove the total backlash in the steering column.

Steering design

The design of the steering system of the movement in modern cars is almost the same for most output models; There are only non-accepted differences.

Steering wheel.
Intermediate cardan type hinge.
Steering gear.
Left and right traction.
Internal and exterior tips.
Adjusting thrust.

Principle of operation

To understand what is a backlash, we consider the principle of operation of the steering in a modern car. The steering wheel through the cardan hinge is connected to the mechanism representing a hollow (usually duraluminum) pipe, inside which is located a gear rail, moved by the gear connected to the cardan hinge. The toothed rail through the inner tips is connected to the traction, which through the outer joints are connected to the turning levers on the front suspension racks. Thus, any movement of the rail leads to the rotation of the wheels and any play in the steering control can lead to serious consequences from the delay of the reaction to movement to the full loss of car control.

The reasons from which the backlash playback occurs:

bad tightening nut mounting steering wheels;
wear of slotted compounds;
deposit of cardan compounds of the intermediate shaft;
weakening the mounting of the steering mechanism to the body;
increased gap between the toothed rail and gear in the mechanism;
wear lugs;
wear of rubberometallic hinges, fastening thrust to the mechanism or the weakening of their fastening bolts;
weakening tightening adjustment pull.

The backlash can be accompanied by a knock in the steering column, which can talk about wear details.

Causes of Steering Handle

It is quite simple to determine the reasons for the back of the backup. To do this, install the car on a flat pad, open the hood, set the wheels to the position corresponding to the straight movement and sharply turning the steering wheel in both sides to a small angle (for this you will need an assistant) forbid all the nodes due to the malfunction of which the backlash appears in steering control. Your hand will immediately feel faulty knot According to the characteristic shift during the wheelchair.

Weakening of the tightening of the naika

The most "harmless" cause of the advent of the admissible handheld of the steering wheel is the weakening of the steering wheel fastening due to turning into the nut of its attachment. To eliminate this fault, it is enough to remove its decorative trim and the protes key of the appropriate size to tighten the nut with the recommended point. On most modern cars In the trim, the airbag module is installed, which will need to be dismantled to provide access to the fastening nut. Therefore, all work must be carried out with special care, disconnecting the terminals from the battery.

Weakening the tightening of the fastening of the steering wheel leads a more unpleasant problem - due to turning it on the axis, the slots of the slots begins at the connection site, which leads to the loss of control. Repairs consisting in mandatory replacement of damaged parts, in this case it is necessary to be carried out immediately. Wear cardanic hinges On the intermediate shaft leads to the so-called "gear effect", manifested by the fact that during the rotation of the steering wheel, its periodic wiping takes place. Such a malfunction leads to a deterioration in the controllability of the machine, especially at high speeds. In this case, the intermediate shaft is necessary.

Another reason for the causing handhelter is the weakening of the steering mechanism to the body or the precipitate of rubber gaskets between the steering mechanism and the body. If this trouble occurs, it is necessary to suspend the mechanism fastening nuts, or replace the worn rubber parts. The elevated gap in the rack gears either does not promise anything good. It appears due to the development of surfaces of contacting the toothed rail and gears. Also in this mechanism, the gaps between the rail and guides are relatively often often increasing. Moreover, the process of wear accelerates at times in case of violation of the integrity of protective anthers.

Wear tip tips

The backlash is especially dangerous in the steering control, the cause of which is the wear of the exterior tips. Tips of craving, it is perhaps the most vulnerable In the entire management system. This happens because they work in difficult conditions, constantly exposed to water, dirt, etc.

The seriousness of the malfunction lies in the fact that as a result there is a significant increase in axial and radial gaps in the ball joint, and, in the end, it is destroyed, as a result of which the car loses control. Predict the consequences of such a malfunction, especially at high speed, it is not difficult. In such cases, it is necessary to immediately contact the auto repair shop to replace the tips.

The inner ends of the thrust are attached to the steering mechanism through the rubberometallic hinges pressed into their ends. In the case of wear of these hinges, a characteristic metal knock is heard when turning the steering wheel. To eliminate this malfunction, you need to pinch new traction. This work requires the presence of press equipment, so it is better to spend it under car service. Either turning off bolts fastening the thrust to the mechanism. In this case, to reduce and eliminate the backup, this bolts are sufficient to tighten the one by the specified manufacturer.

How to adjust the backlash

Well, finally, another cause of the causing backlash in the steering is to attenuate the tightening of the adjusting thrust, which are designed to adjust the convergence of the car's wheels. This is a consequence of a bad tightening of the bolts on these traction after adjusting the angle of convergence, and can lead to an increase in the adjusting thrust from the tip.

On some models of modern cars, turning levers are not welded to the suspension stands, and are articulated with a bolted connection. The weakening of these compounds also leads to the appearance of the described trouble. To exclude this option when determining the reason that led to it, you need to raise the front part of the car and removing the wheel to check the tightening of the above connections, thereby adjusting the steering.

Conclusion

As can be seen, the overwhelming majority of the causes that cause the appearance of the handle of the steering wheel can lead to very serious, and sometimes, even fatal consequences. To prevent such a fault, it is necessary to periodically inspect all the knots and steering mechanisms. Wherein special attention When inspection, you need to be given to check the integrity of rubber anthers on the mechanism and tips of the thrust. If it turned out that these anthers are torn, then it is necessary to replace them as quickly as possible. Well, if it turns out that the moment is missed, and it is impossible to correct the backlash, then we are not recommended to try to eliminate it yourself, the best solution will contact the car service, in which professional wizards will hold all the necessary work.
