In the process of movement vehicle Very often there is a need to adjust the direction of movement: for example, when turning and reversal, rebuilding, overtaking, ahead, circulation, etc. The implementation of the specified car maneuvers provides the steering system. During the operation of the car, its nodes and aggregates come into disrepair. Steering faults - this is one of the most pressing issues. technical status transport.
Signs and causes of faults: technical aspect
The dysfunctional state of the roads (especially, Russian), ignoring the driver of the rules of operation of its vehicle (violation of service periodicity, low quality components), the unskilled value during technical and maintenance and the location of the car leads to unstable work control systems. 
The most common sign of the steering fault is the backlash. According to technical characteristics, the backlash is not working (or "idling") the stage of functioning of the node. For example, when you turn the steering wheel to a certain angle until a certain point, the control wheels are moved. This is the backlash.
The main causes of such dysfunction are:
- wear of the so-called "ball" (hinges of the tip of the steering thrust);
- wear of the steering mechanism (pair of "worm-roller" or "gear-rail");
- steering shaft bearing wear.
The backlash, thus arises, first of all, as a result long operation car.
The second type of malfunction is a knock and beating of the steering wheel, which are very often caused by the wear of the notorious "ball" and the destruction of the bearing on the steering shaft. 
Some of the faults is determined by the problems of the functioning of the hydraulic, electrical or pneumatic strengthening of the steering wheel connected to the wear of the nodes of this subsystem (disorder of the tightness of the mechanism, the destruction of the parts of the pump or the compressor, etc.).
The elimination of these problems is conjugate, as a rule, with the replacement of worn and destroyed parts. Therefore, the repairs are desirable to carry out with the involvement of highly specialized car service professionals.
Faults: Legal Aspect
Unstable management of the management system, according to specialists, is a serious factor destabilizing the road traffic. Indeed, this condition of the car is thoroughly "beats" safety on the road. The driver is deprived of the opportunity to control the trajectory of movement of his vehicle adequately, which can lead to the loss of its manageability and, as a result, to deplorable consequences. 
This is determined by the action of the next legal norm, prescribed in traffic rules: the driver is categorically prohibited to move with such faults. With their occurrence, it is necessary to immediately stop, trying to eliminate them in place. In the event that it is impossible, you should refuse the operation of the car.
The indicated steering faults are provided for by a special regulatory act - "the main provisions for the admission of vehicles to operation ...".
- The total backlash in the car's steering exceeds the established values: for passenger cars - 10 degrees; For buses I. trucks - 20 and 25 (respectively).
- There are movements of nodes and parts of the system that are not provided for by the design of the car.
- There is no further threaded connections.
- There is no or in a faulty state of the steering steering stipulated by the design.
Even a runaway analysis of this list of faults will make a conclusion about their extremely negative role in ensuring safety on the road. Serious administrative sanctions for movement on a faulty vehicle are well-founded. COAP RF provides for the removal of the driver from the management of the car, detention the latter, the prohibition of its operation, conjugate with the removal of state regnet from the car, as well as administrative penalty in the amount of 500 rubles.
Let's summarize
Any vehicle malfunction can with different degrees of probability influence its handling. However, the steering instability is recognized as one of the most serious, in the presence of which the operation of the car is strictly prohibited. Qualified repair, timely service maintenance, High quality components, gentle movement mode are the most effective means of content management in proper condition.
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;
- wear cardan compounds 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 the faulty knot according to the characteristic shift during the wheel swaying.
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. Repair consisting of mandatory replacement damaged partsIn this case, it is necessary to be made 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 that causes the retainer steering is to weaken the mounting of the steering mechanism to the body or precipitate rubber pads 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. Tie tips, it is perhaps the most vulnerable space 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.
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 the installation of a 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
From boredom was boring ..As far as I know, the angle of non-extensibility of the steering wheel in Japanese cars (practically) is completely lacking - a good steering system responds immediately on the rotation of the steering wheel.
To know where to dig, you need to make two simple checks:The first, on the backlash in the system of the hydraulic agent:
Possible malfunctions (three main):
a) the backlash in the steering charter - between the ram and the hydraulic system - is treated with the replacement of the cardanchik (hardly expensive),
b) the backlash in the system of the hydraulic agent - in the place where the steering wheel stick enters the horizontal steering rack - This is the most boring diagnosis. Here, of course, you can climb the nut, but there is not enough for a long time - it will be afraid. treated with the replacement of the steering rack
c) Schedule in end steering. It is treated with a replacement of steering.What are the checks:
- Include the engine, music, all the audience to be silent, do not pull out the key from the castle, slightly (!!) twist the steering wheel back. Listen to your hands and sounds. If nothing felt / did not hear, then there is no backlash. If there is a small beating / pouches, then the backlash-dog is.Touch the car on the overpass or go to the pit.
- Speed \u200b\u200byour friend behind the wheel, teach it not to pull the steering wheel, do not include music, do not start the engine. He, of course, can be boring, well, let it be.
-Same climb under the car. and spend three checks to decide where there is a backlash. At this time, the root is slowly pulling the steering wheel there / here. And without fanaticism.
- Here is the backlash only with your hands. On the end steering traction, on the hydraulic rail rail and on the steering wheel cardanchik.The second check - for convergence and collapse (if available) wheels. It is carried out after the backlash will be eliminated, including in ball supports. Otherwise, all this is free and money for the wind.
Home Checks:
The steering wheel should stand smoothly
and while driving listen to yourself - do you constantly finish the steering wheel on a little bit when you go straight
Rubber should not eat. at all. I mean, it should be ejected evenly throughout the entire width of the tread.If the checks gave a negative result - extex on the stand. And in the search, where that uncle Vasya with golden hands, which the sinks makes a lot of stand on his stand.
After all the backs were eliminated,
Golden hands with love adjusted convergence / collapse,
And your car stubbornly drags into the gateway or on the opposite, and she eats rubber like a hungry dog \u200b\u200b- that it was once smashed to your car, and there are problems with the body geometry.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 good, and the threaded connections are tightened, the hood adjustment of the steering wheel of the 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.
