What s wrong with the car? What to do if the car deviates

The deviation refers to the phenomenon that the steering wheel can automatically return to the right on a flat road, but the driving direction of the car deviates to one side, which is actually due to the positioning of each wheel, and the angle or the height of the body, resulting in the inconsistency between the center line of the front and rear axles of the vehicle and the line of the direction of the vehicle's driving trajectory. There is still a difference with a bad steering wheel. Slight deviation will cause tire gnawing, tire scrapping, and in severe cases, it will cause tire bursts, vehicle loss of control and other dangers.

There are five main reasons for car mistracking.

The first reason is mainly caused by the inconsistent tire pressure on the left and right sides of the driving wheel, resulting in the different friction between the tire and the ground and causing misalignment. Therefore, checking the tire pressure is the first step to solve the mistracking.

The second reason is the inconsistency of the left and right tire patterns or depths. The grip of the old and new tires is different, if one side is a new tire and the other side uses an old tire with a large wear gap, there will be a mistracking, in which case the tire needs to be replaced.

The third is suspension system failure, such as suspension injury, deformation, displacement, etc. This situation will cause the tire alignment to not be adjusted to the standard position, which is a more serious problem that requires four-wheel alignment to adjust or replace faulty suspension accessories, which is more common.

The fourth reason is that the wheelbase on the left and right sides is inconsistent, the overall deformation of the body, the difference between the front and rear wheel tracks on the left and right sides is large, and the vehicle will deviate to the side with a short wheelbase when the car is moving.

The fifth reason, caused by road factors, because the road on both sides of the drainage system, in general, the road is high in the middle and low on both sides, this situation is not easy to detect the road factors when driving, but for the direction-sensitive model after driving 100-200 meters, the vehicle will deviate to the right. In this case, we have to recall whether there is deviation on all roads, or it is particularly obvious on a certain road, and then analyze whether the road surface is tilted.

There are many reasons for car mistracking, the main reasons are as follows: insufficient air pressure in the tires; The degree of wear of the tread pattern is not the same; There is a problem with the design of the suspension system; Suspension injury, deformation, displacement; The quality of the steering system will also affect the straight driving of the car, which needs to be judged according to the actual situation.

Chen Gong chats about cars: Talk about buying cars, using cars, maintaining cars, and repairing cars.

The function of four-wheel alignment is to prevent the vehicle from deviating, generally each four-wheel alignment is carried out at about 10,000 kilometers or 20,000 kilometers once, but if you enter the field to drive a long distance, or to take a mountain road, you may need to reduce a certain mileage, but if the vehicle deviates, no matter how many kilometers you drive, it is best to carry out a four-wheel alignment work to ensure the line of the vehicle.

1. Changes in four-wheel alignment data, changes in four-wheel alignment data will cause deviation, which is also a problem that many car owners will ignore, especially those vehicles that often walk in potholes, the parameters of four-wheel alignment are more likely to change, and the solution is that if you find that the car is driving off, you should go to the 4S shop in time to do a four-wheel alignment;

2. The tire pressure on both sides is unbalanced, in fact, the reason is very simple, if the tire pressure on both sides is unbalanced, on the flat road surface, the left and right are high and low, the vehicle will naturally run to the side of Jing Hongyin, the solution is to check whether the tire pressure on both sides is normal, and if the air is lost, then pump and fill;

3. The braking system fails, if the braking occurs, the car will deviate, which may be a problem with the braking system, the side of the wheel that deviates from the bright hall tire contains the brake pump, resulting in the brake pad can not return normally, the equivalent wheel has been in a slight braking state, resulting in the operation deviation, the solution is to check the braking system in time;

4. Chassis problems, changes in the main components, may be due to wear and tear caused by daily driving, or may be due to accidents caused by frame deformation, aging problems are easy to say, if the lower swing arm and other parts of the change or the gap is too large, you can adjust or replace the parts, if it is due to the body deformation caused by the accident, frame damage and other deviations, it is more serious, need to replace parts in a large area or even frame correction, in order to fully recover. The solution is that I can't solve this problem by myself, so I can only send it to a repair shop for processing.

What is the case of mistracking. Check the brakes first for brake misalignment. Four-wheel alignment is done first.

Hello, there are many reasons for vehicle deviation, do four-wheel alignment can judge the cause of the reference data, if there is a vehicle deviation phenomenon, first need to check the condition of the chassis, confirm that the chassis suspension parts do not exist deformation, looseness, looseness, displacement, failure and other phenomena, and the tire pressure value is normal, and then you can repair the deviation through the four-wheel alignment adjustment.

There are three main reasons for the deviation of the car, namely: 1. The driving tire pressure is inconsistent, resulting in the different degrees of wear and tear between the driving wheel and the ground, which causes the deviation; 2. Suspension system failure, such as suspension injury, deformation, displacement, etc., will cause deviation; 3. The wheelbase on the left and right sides is inconsistent, and the vehicle will deviate to the side with a short wheelbase when the car is moving.

1. Tire pressure is unequal.

It is mainly caused by the inconsistent pressure of the driving tire, if the left and right tire pressure are not equal, it will cause the wear degree of the driving wheel and the ground to be different, and different friction will also directly cause deviation. The solution is to go to the car maintenance shop to check the tire pressure.

2. Suspension system failure.

Suspension system failures can also cause the car to mistrack, such as suspension injuries, deformation, displacement, and other ......There will be deviation, such a problem is more serious, once the problem is found, try to do a repair.

3. The wheelbase on the left and right sides is inconsistent.

After a long period of use, the vehicle will inevitably encounter bumps and bumps. When the overall deformation of the vehicle, the difference between the wheelbases on both 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.

The reasons for the deviation of the car are: 1. The tire pressure is unequal, if the left and right tire pressures are not equal, it will cause the wear and tear of the drive wheel and the ground to be different, and different friction will directly cause the deviation, you can go to the car maintenance shop to check the tire pressure; 2. Suspension system failure, such as suspension injury, deformation, displacement, etc., will cause deviation, such a problem is more serious, once the problem is found, try to do a repair; 3. The wheelbase on the left and right sides is inconsistent, the vehicle will inevitably encounter bumps and bumps after a long period of use, the overall deformation of the vehicle, the wheelbase difference on both sides is too large, and it has not been corrected in time, or does not meet the technical requirements after correction, when the car is driving, the vehicle will deviate to the side with a short wheelbase.

I found that there is an interesting phenomenon in the car rim, that is, many old drivers have some misunderstandings when driving, which indirectly leads to the understanding of some novice drivers for vehicle failures has also deviated, the biggest misunderstanding is the four-wheel alignment and dynamic balance, many novice drivers generally think that as long as the vehicle chassis is uncomfortable, the first thing that comes to mind is to do four-wheel alignment, in fact, this is a very big misunderstanding, this topic we will focus on four-wheel alignment and dynamic balance, to talk about the functions and roles of the two in detail.

High-speed jitter dynamic balance, the vehicle deviates and eats tires to do four-wheel alignment.

First of all, we must emphasize to you that four-wheel alignment and dynamic balance is not omnipotent, we must clearly know the cause of our vehicle failure before doing four-wheel alignment and dynamic balancing, and we must do the right medicine, otherwise it will be in vain.

1. Dynamic balance, the main function of dynamic balance is to balance both sides of the tire, so that when the tire is driving at high speed, the tire will not cause the entire body to swing because of the violent swing, under normal circumstances, as long as the tire of our vehicle is disassembled, the dynamic balance must be done, because the tire is not a uniform circle in the production process, if the vehicle travels to 80km h, the vehicle shakes violently, then it can basically be concluded that the dynamic balance data is too large.

2, four-wheel alignment, four-wheel alignment is more professional, four-wheel alignment involves the adjustment of the entire vehicle chassis, generally speaking, long-term driving in the road conditions with poor vehicles, the chassis will inevitably loosen, at this time the data error in all aspects of the chassis will become larger, and these changes in the data directly reflect the situation is the vehicle deviation and tires eat tires, as long as the vehicle appears in such a situation, it is necessary to immediately do four-wheel alignment.

There is a big difference between a vehicle mistracking and a tire eating a tire!

1. Vehicle deviation, in fact, vehicle deviation is divided into two situations, one is the steering wheel is crooked, and the other is the vehicle is crooked, everyone must learn to distinguish.

A crooked steering wheel is when the steering wheel of a vehicle deviates slightly at an angle, but the vehicle can stay in a straight line at that angle.

Crooked vehicle refers to the situation in which the steering wheel position is kept in the center, and the vehicle involuntarily looks at the left and right sides.

Under normal circumstances, the deviation only needs to adjust the ball head of the external tie rod on the steering machine, and the effect is very good with the data on the four-wheel positioning computer.

At this time, the first thing we need to adjust is the camber angle of the vehicle, generally starting from the rear suspension of the vehicle chassis, adjusting the inclination angle of the rear suspension after adjusting the rear suspension, and then adjusting the inclination angle and toe of the front wheel of the finch circle.

To sum up, when drivers find that there is a problem with the vehicle chassis, they must communicate clearly with the auto repair shop, first determine whether there is a problem with the vehicle chassis, and then they can do four-wheel alignment calibration, otherwise it is useless and cannot solve the problem in the real sense.

Do a four-wheel alignment.

The factors that cause the deviation of the car are tire pressure, brake pads, and tire wear, which are analyzed as follows

1. Tire pressure. Tires are the only way for a car to contact the ground, and they are also an important factor that affects braking, in addition to the braking system. Tire pressure that is too high or too low will cause potential safety hazards, so be sure to pump according to the manufacturer's standards.

If the tire pressure on one side is higher than that of the other tire, it will cause brake mistracking.

2. Brake pads.

Different wheels will get different braking forces during braking, so the degree of wear between brake pads is also different. If the brakes are misaligned and the tire pressure is normal, check the wear of the individual brake pads.

3. The degree of tire wear.

The degree of wear and tear of the tires is also one of the reasons for brake mistracking. The grip of old and new tires is different, and if one side is used with a new tire and the other side is used with an old tire with a large difference in wear, there will be mistracking.

The solution to the deviation of the car

1. First, check whether the tire pressure is normal, if the tire pressure is abnormal, it will cause the direction of the car to deviate; It is also necessary to check whether the tire pressure is consistent, and many times the tire pressure is inconsistent and causes the car to deviate.

2. Do four-wheel alignment for the car, which can effectively correct the deviation of the car.

3. Check the tires of the car, if the tire pattern of the car is obvious, such as the pattern of a tire is very deep, and the pattern of a tire is very shallow, it will also cause the direction of the car to deviate, and in this case, the tire needs to be replaced.

4. Check that the tire pressure of the car is normal, do the four-wheel alignment, check the tire pattern and still can't solve it, it is recommended to check whether the suspension is faulty, if the suspension is deformed, damaged, displaced, etc., it will cause the car to deviate.
