What happens when the car deviates while driving?

The main causes of vehicle deviation and solutions.

1. Tire pressure problems.

The inconsistent air pressure on both sides of the tire is an important cause of car mistracking. If the air pressure of the two tires is different, the area of contact with the ground is also different, and on normal road surfaces, the friction of the tire with low air pressure is greater, so in this case, the vehicle will deviate to the side of the tire with low air pressure.

How to solve: If the vehicle is found to be misaligned, it is recommended that the owner first check whether the air pressure of the tires on both sides is within the standard range value. The correct way to test the tire pressure should be to use the tire pressure gauge to test the tire in a cooled state, so as to ensure that the measured tire pressure value is accurate.

If you find that the deviation is indeed caused by air pressure problems, you should use an air pump to replenish the tire pressure in time. The car is equipped with the car pump LG600, with blue light backlight pressure gauge, fast pumping speed, the built-in tire pressure gauge can not only detect tire pressure, but also can be inflated immediately when the tire pressure is insufficient and the tire is leaking, lack of air, when the tire pressure is too high, it can also be properly depressurized, and the air pressure can be replenished anytime and anywhere, and the tire pressure can be kept normal at all times.

Second, the four-wheel alignment is inaccurate.

For vehicles that have been driven for a period of time, changes in wheel alignment data can lead to mistracking. The camber angle of the front wheels, or the toe-in angle is too small, can cause mistracking. When the four-wheel alignment value is out of alignment, the vehicle will feel heavy when turning, and the tires will be eccentric, resulting in mistracking.

Long-term high-speed driving on uneven roads can also lead to inaccurate four-wheel alignment data.

How to solve: In the event of the above fault phenomenon, the four-wheel alignment adjustment must be carried out in time. In addition, it is recommended to replace new tires or after a collision accident maintenance needs to make four-wheel alignment adjustments for safety.

In addition, it is recommended that the owner should drive less on the road every day, reduce the speed when passing the big pothole, as long as it is normal driving, it is generally not necessary to do four-wheel alignment for one or two years. But if there is a situation, it must be dealt with.

The reasons for the deviation of the direction of the car during driving include insufficient air pressure of the tires, different degrees of tread pattern wear, problems with the design of the suspension system, suspension deformation, displacement, etc.

There are several situations in which the car will deviate: 1. Unbalanced loading.

2. The tire pressure on both sides is inconsistent, the solution is, of course, to add the standard tire pressure, and see if the wear of the wheels on both sides is inconsistent, so that the wheel diameter and gravity are different.

3. The degree of wear of the tread pattern is not the same, and it will deviate; If the springs and shock absorbers are damaged, focus on the lower side to see if there is any overcompression of the spring due to insufficient elasticity and oil leakage from the shock absorber.

4. Suspension injury, deformation, displacement, etc. will cause deviation.

5. The quality of the steering system will also affect the straight line of the car.

Automobile deviation is the process of driving in a straight line on a flat road, and the car deviates to one side by itself, resulting in the inconsistency between the center line of the front and rear axles and the center line of the driving trajectory. If the deviation is light, it will cause tire gnawing and tire scrapping, and at worst, it will cause tire burst, vehicle loss of control and other dangerous conditions.

Deviation is generally the four-wheel alignment data ran away, and you have to do the four-wheel alignment.

The tire pressure of the front and rear tires is not the same.

First of all, you have to see if the tire pressure is normal, if it is normal, then check the steering mechanism and triangle arm and connecting rod ball joint, steering ball joint, these are okay, the front shock absorber must be broken. That's pretty much it.

The most direct way to adjust the steering wheel is to adjust the steering wheel is Sixian Chang wheel positioning, but now many car owners want to do it themselves, so let's take a look at the way to adjust the steering wheel by yourself. Note that there is a certain risk in doing it yourself, and the risk is that there is no change or more serious impact after adjustment, so please choose carefully.

First of all, we must be clear that this adjustment is the steering lever, which is an important part of the steering mechanism of the car, which directly affects the stability of the car operation, the safety of operation, and the service life of the tire. As shown in the figure, if the steering lever is long on one side and short on the other, it will cause the car to deviate to the longer side.

Adjusting the length of the steering rod does not require us to "cut shorten" or "extend", but to "screw in" or "spin out" the base of the lever. Start by preparing the wrench, then knock the steering wheel of the vehicle to the right to expose the rear of the left front wheel. As shown in the figure, first loosen the fastening nut with a wrench, and then rotate the left tie rod clockwise, clockwise is the position of the tie rod relative to the base of the tie rod, and the left tie rod "screw" is shortened.

Then repeat the previous steps and knock the steering wheel to the left to expose the back of the right front wheel. Similarly, first loosen the fastening nut with a wrench, and then rotate the right tie rod counterclockwise, and the right tie rod "unscrewed" is elongated.

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.

There are many reasons that can lead to the deviation of the vehicle in the process of driving, if the tire pressure on both sides is inconsistent, it will also lead to the deviation of the vehicle, some problems with the suspension, and it will also cause the vehicle to deviate.

If the car deviates, the wheels should be positioned, and it is good to do a four-wheel alignment directly.

1.Tire loss.

2.Problems with the braking system Some cars have a slight deviation when driving, and this phenomenon will be more obvious when braking. In this case, it is very likely that there is a problem with the brake cylinder, which causes the brake pads to not return normally, which is equivalent to a certain side of the wheel has been in a state of slight braking, resulting in it.

3.Chassis problems If it is caused by the chassis, then it is relatively serious. This may be due to the wear and tear of the vehicle caused by daily driving, aging, and in severe cases, it may be due to the deformation of the frame caused by the accident. As.

There are many reasons for vehicle deviation: different tire patterns on both sides or different heights from deep to shallow, unequal tire pressure on both sides, inconsistent vertical cushioning on both sides due to deformation of the front shock absorber springs, failure of the front shock absorber or excessive wear of vehicle chassis components, and abnormal clearance.

1.The tire pattern on both sides is different or the depth and height of the pattern are different. It is best to use the same type of tires for the whole car. At least the two tires on the front axle and the rear axle must be the same, and the tread depth must be the same. If the wear limit is exceeded, it must be replaced.

2.The tire pressure on both sides is not equal. Unequal tire pressures can cause tires to vary in size, which can inevitably deviate when rolling.

3.The shock absorbers on both sides of the front shock absorber spring deformation are inconsistent. The quality of the shock absorber springs can be judged by the comparison after pressing or dismantling.

4.The front shock absorber failed. After the failure of the front shock absorber, when the vehicle is driving, the two suspensions are unevenly stressed, one high and one low, resulting in deviation.

The absorption of the shock absorber can be detected by a special shock absorber tester, and the quality of the shock absorber can be judged, for example, unconditional disassembly can be judged by pulling.

5.Excessive wear and tear of vehicle chassis parts with abnormal clearances. Steering rod ball joint, rubber sleeve for support arm, rubber sleeve for stabilizer bar, etc. It is a common part with too much clearance and should be carefully inspected by the lifting vehicle.

6.A certain wheel of brake return is poor, and the separation is incomplete. This is equivalent to the fact that partial braking is always applied on one side of the wheel, and the vehicle will inevitably deviate while driving.

When inspected, the temperature of the hub can be felt. If one wheel is super fast and more than other wheels, it means that the brake return of this wheel is poor.

7.The overall deformation of the frame. If the wheelbase difference between the two sides is too large and exceeds the maximum allowable range, it can be measured with a tape measure. If it is out of range, it must be corrected by means of a calibration table.

Millions of car purchase subsidies.

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.

One side of the tire pressure is low, the inclination angle is wrong, the chassis is abnormal wear, etc.

All of the above may complete the mistracking. Thank you.

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).

That's the reason why the toe is wrong, just do a four-wheel alignment.

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.
