What happens when the car deviates?

It is recommended that you do the 4th round of alignment.

First, if there is a feeling of deviation, then first judge whether the road is a problem If the road surface is tilted, then the car will be biased to the lower side. General roads, for drainage and other considerations, are basically high in the middle and low on both sides, the car is driving on the right, there will naturally be a tendency to deviate to the right, the greater the slope of the road surface, the more obvious this tendency is, to one.

If the air pressure of the left and right tires is inconsistent, or the front wheel alignment is inaccurate, it must be tested at a professional maintenance point.

What happens when the car deviates? Deviation is generally the four-wheel alignment data ran away, and you have to do the four-wheel alignment.

The reasons for the deviation of the car while driving are as follows:

1. The road condition is uneven, and the design of the flat ordinary highway is high in the middle and low on both sides, which is because it is necessary to reduce the accumulation of water in the rain.

2. The tire pressure is inconsistent, if the tire pressure on both sides is unbalanced, then driving on a flat road, the natural wheel will deviate to the side of the gas loss.

3. The tire wear is uneven, and the position of the tire should be changed regularly, because the wear of the driving wheel will be greater than that of other wheels, and the inconsistent tire pattern on both sides will also cause the direction of the car to deviate.

4. Damage to the chassis suspension system components, such as knuckle arm, knuckle bending deformation, shock absorber deformation, loose ball joint of swing arm, etc.

5. The mileage is too long and the road conditions are poor, resulting in changes in tire positioning parameters.

6. When the accident repair parameters are unqualified, such as the length of the wheelbase on both sides is inconsistent, the wheelbase difference between the two sides is too large, and it is not corrected in time, or the correction does not meet the technical requirements, when the car is driving, the vehicle will deviate to the side with a short wheelbase.

There are many reasons why a car mistracks, and here are a few examples.

1. Tire problems (1) The tire pressure on both sides is not high, and it will deviate to the side of the tire with low tire pressure.

2) The depth of the pattern on both sides of the front wheel is different, so it will also run to the shallow side of the pattern.

Second, the suspension part (1) the shock absorber has the oil leakage, causes the shock absorption to be lower than the normal side under the effect of the vehicle's own pressure, causes the body height to be lower than the normal side, and the vehicle center of gravity shifts to the side of the body low, causes the shock absorption side of the oil leakage to deviate.

3. Positioning data (1) The positioning data is incorrect, which also leads to deviation, and the side of the vehicle with a large camber angle is deviated.

2) The vehicle runs to the side with a small backward angle.

3) vehicle walks along the thrust line direction, and the thrust line and the geometric axis do not coincide, so that the vehicle may deviate to the corresponding thrust line declination direction.

Fourth, road surface reasons. Due to the design of road drainage, some road surfaces are high in the middle and low on both sides, and we are driving on the right side, so our vehicle may receive the influence of this design and deviate to the right.

Therefore, the reason for deviation is a comprehensive reason, and the main factors of deviation should be comprehensively analyzed.

1. Without braking, the tire wear is seriously uneven, and the difference is that the larger the diameter difference between the inner and outer tires of the rear wheel, the more serious the irregular braking deviation. Because this diameter difference will lead to the pressure of the wheels on the ground to change at any time with the unevenness of the road surface, the braking torque of the wheels is seriously out of balance when braking, 2, the tires are good to run the deviation, it is necessary to do a four-wheel alignment, I was in this situation before, the four-wheel alignment shop can deal with it.

1. The air pressure of the left or right tire is inconsistent;

2. The left and right wheelbases are inconsistent;

3. Deformation of one side of the steel ring;

4. The front wheel alignment is incorrect;

5. The front wheel leans back incorrectly;

6. The two sides of the tire wear are different;

7. The toe is wrong;

8. The friction plate of the wheel of one side of the car is locked (the piston of the sub-cylinder is stuck after braking).

The direction of the car cannot be completely straight, for example, it deviates by one millimeter at the start, and after driving in a straight line for dozens of kilometers, it is not a deviation of several hundred meters.

Check the deviation, generally when driving, correct the steering wheel, and then let go of the steering wheel to see if the car is in a straight line. If you don't go in a straight line, you're off track.

First of all, mistracking may be caused by the inconsistent air pressure of the left and right tires, and it is necessary to inflate insufficient tires.

The second possibility is that the front wheel is not aligned properly. The camber angle of the front wheel, the kingpin angle or the inner angle of the kingpin are not equal, and the toe is too small or the toe is negative will cause deviation, which must be tested at a professional maintenance station.

When the car is running off, it is recommended to do a four-wheel alignment, adjust the suspension parameters, long-term deviation, has a great impact on the safety situation, resulting in tire eccentricity, and affect the control of the car, it is recommended to repair as soon as possible, if it is useful, please adopt.

It's OK to do a four-wheel alignment.
