Adjustment of camber-toe of wheels. How to adjust the alignment. Stand for adjusting the camber-toe of the wheels

Today on any SRT the adjustment of camber-toe of wheels is offered. However, car owners can carry out this procedure on their own. So they will learn to better understand and feel their car.

In SRT or independently?

Automechanics unanimously assert that it is extremely difficult to independently adjust the similarity-collapse. In fact, this is not so. Also, do not rely too much on specialists from the service station, who claim that these parameters in the car are violated. In car service centers it is suggested to install the car on the stand to adjust the camber-toe of the wheels and, based on the readings of this apparatus, perform professional tuning. In this case, do not rely on professionalism. Now really qualified specialists are getting smaller and smaller. But still there are masters who can do this job qualitatively.

Without the help of stands, they can perform precise diagnostics of the parameters of the similarity-disorder, put the correct diagnosis about various violations of geometric characteristics and perform repairs. But motorists with experience prefer to perform these operations with their own hands. So you can get a more accurate result. And let the ways with which the adjustment of the camber-toe-in of the wheels is done, are already pretty outdated, but nevertheless they are and show fairly accurate results.

Crumbling

Under this parameter, one must understand the difference between the distances from some conditional points. This is the angle that is drawn vertically and in the plane of rotation of the wheel. If this angle of collapse in the red, the upper point on the wheel is directed inward, into the wheel arch. If in the black, then on the contrary - out. In order to correctly adjust this parameter, you must adhere to strict conditions. It is important that the tires have optimum pressure. The flat wheels are also a guarantee of the right angles. For adjustment it is required that the steering wheel has a normal backlash or free stroke. Before you start the diagnosis, you need to make sure that all the main hinges and knots in the suspension system were fully in service and not worn out. Adjust camber by reducing or increasing the number of spacers. They are located between the rack eccentric and the axis of the lower arm. Now you can find on sale special adjustment plates for the adjustment of camber. They are suitable for the wheels of rear-wheel drive cars of domestic production.

Convergence

This is the parameter of the direction of the machine and the plane of rotation of the driving wheel. Often you can hear from professional mechanics about the sum of the angle of convergence of the wheels on one axis. There are cars where the adjustment of the camber-toe of the wheels on each of the axles is performed. The correctly set parameter on the driving wheels is one of the most important factors in determining the stability of the machine. The convergence is determined by the sum of the differences between the rims of the wheel rims in the rear and front positions. Measurements are made at the center of the height of the disk between the same points on the rims.

If the data does not correspond to the normal, then it is necessary to expose the angles of convergence. To fine tune it is possible to proceed only after checking the reliability of fastening the levers and the turntable. This connection must be as reliable as possible. Also diagnosed ball, mounted on the steering rods. For a good result, you should additionally check the reliability of fastening the bipod and pendulum mechanism. It is important to remember that after any repairs in the undercarriage of the car, adjustment of the camber-toe of the wheels is required. This is done by changing the length of the lateral steering rods.

Caster

This is the angle that passes between the vertical and the projection of the pivot axis for a particular wheel and the longitudinal plane of the car. Due to the inclination in the longitudinal part, the machine is leveled at speed. That is, she herself comes out of the turn, if you release the steering wheel. Whichever the angle of rotation is, the vehicle will automatically return to its straight-ahead position. Naturally, so the machine will behave if the adjustment of the angles of camber-toe of the wheels is done correctly. The same behavior can be observed with a properly configured caster. On conventional cars, this angle is more than 6 degrees. Athletes race car drivers adjust this parameter a little higher. This will make the car more stable. Also will increase the desire of the car to move rectilinearly.

What are the reasons for the collapse-convergence?

Adjusting this gives the machine more stability. Improves manageability. Also, the right angles reduce the likelihood of skidding. And again: if all corners are set correctly, then the tires will not wear out so intensely, and fuel consumption will decrease.

When do we need adjustments?

The adjustment is necessary if the machine constantly moves in one direction or the other from the rectilinear motion when driving. Also, the need for customization is indicated by worn tires only on one side or uneven wear. If it is a rear-wheel drive vehicle, it is additionally checked whether adjustment of the camber of the convergence of the rear wheels is required. When visually diagnosing the tread on the front axle, it is recommended to carefully check the condition of the trough. Its edges are important. When the edges of the gutter are the same, this is a good sign and there is no reason to worry. If one of the edges of the groove is pointed, and the other is normal, then there is a problem.

However, this is important only in a calm manner of driving. Adjustment is also necessary if there are certain difficulties in performing some maneuvers.

Setting up a self-destructed demolition: ways to

There are several methods that are suitable for setting the angles of the convergence. For example, you can use a laser pointer. There is also a proven method with a telescopic ruler and a plumb line. Such adjustment of the camber-toe of the wheels with their own hands will be carried out, maybe not very accurately, however, all of these tools have everyone.

Before starting work

Before you get started, you need to check some points.

Make sure that identical tires are mounted on each axis. Disks should be as flat as possible. In addition, the rudder is placed in a straight-line position, and then the number of turns is checked to the right and to the left. In order for the adjustment to work, the entire suspension must be in good order. And finally - the pressure in the tires. It must match the manufacturer's settings.

Let's get to work: collapse

If the adjustment of the camber-toe of the front wheels is performed, then they are set in the forward direction. Further, at the top and bottom point make a mark. Then a plummet is applied to the wing and the distance between the cord and the rim is measured.

The machine needs to be rolled forward so that the wheel is shifted by 90 degrees, and then you need to perform the same measurements. For work it is necessary to dismantle the wheel. Also unscrew bolts that connect the shock absorber to the pivot. Then the fist is moved to the distance obtained as a result of the measurements. That's all - the angle is adjusted. Now you should collect everything and take measurements again. The camber for a front-wheel drive car is -1 / + 1 mm. In the case of rear-wheel drive - + 1 / + 3 mm.

Convergence setting

The conditions are the same as in the case of the previous adjustment. As for the necessary tool, you will need a chalk and a telescopic ruler. Now marks should not be made outside, but inside the wheel, almost close to the wheel disks. Then the ruler is applied with two ends to the marks. Further the pointer is combined with zero on the ruler scale and fixed. After the car roll a little forward until the line does not move back.

Measurements will show how much it is necessary to adjust the steering rods. If the numbers between the wheels are smaller, then the traction is shortened. If the difference has increased, then they are lengthening. To adjust the length of the rods there is a special coupling.

Adjustment in the service station: prices

Doing a break-up on your own at the VAZ-2106 is a common procedure. But in the case of modern foreign cars, especially for luxury models, it's best to contact professionals. That's what manufacturers recommend. The accuracy at the stand will be very high. For example, in Moscow, many SRTs make a breakdown. The price for passenger cars is from 1500 to 2000 rubles. If this is an SUV and a business class, then the cost will be from 2000 to 2500 rubles.

Trucks will be carried out this procedure at a cost of 2200 to 2500 rubles. Thus, if there is at least a little experience, it is better to regulate independently the collapse-convergence. The price for the service may be small, but if necessary, frequent adjustments, this can result in a quite round sum.

Conclusion

So, we found out how to independently perform the procedure for adjusting the camber-toe of the car's wheels. The adjustment can be made with a minimum set of tools. This knowledge will not be superfluous for any motorist.
