What should I do if my car deviates? What to do if the vehicle deviates

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 fix it:

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 a vehicle pump with a pressure gauge and a fast pumping speed, and the tire pressure gauge can not only detect the tire pressure, but also inflate the tire immediately when the tire pressure is insufficient and the tire is leaking or lacking air, and the tire pressure can be properly decompressed when the tire pressure is too high, and the air pressure can be replenished anytime and anywhere, and the tire pressure can be kept normal at all times.

How to deal with vehicle mistracking:

1. Tire pressure on both sides"Asymmetry", the imbalance of tire pressure on both sides of the vehicle will directly affect the deviation of the vehicle. Solution: If you find that you are misaligned, it is recommended to see if the air pressure of the tires on both sides is normal;

2. There is a change in the four-wheel alignment data, driving on the pothole ground for a long time, and the serious vibration caused by the vehicle driving will affect the change of the main parameters of the position of the relevant parts, which also affects the main parameters of the four-wheel alignment may exceed the limited range of the main parameters, causing inaccurate positioning, then it will cause the car to deviate. Solution: It can only be judged and adjusted by the four-wheel aligner;

3. Brake system problems, such as when driving, the car has a slight deviation to the right, especially in the case of braking, this phenomenon is more significant, at this time, after detecting the vehicle, you may find that there is a problem with the brake cylinder of the right front wheel, causing the brake pads to not return normally, which is equivalent to the right front wheel has been in a slight braking state caused by deviation. Solution: For such a situation, you should pay attention to whether there is a problem with the brake cylinder and whether the wear of the brake pads on both sides is uniform.

There are many reasons for deviation, such as tires, suspension, and steering systems, the most common of which is insufficient air pressure in the left and right tires and water accumulation inside the tires. Your car has checked that the tire pressure is normal, so check whether the tire tread is abnormal, because you have already done four-wheel alignment, then it is recommended that you can try to change the tires of other cars to try, and if it has not improved, you can only start to the mechanical side.

What should I do if the car deviates? Eighty percent of them are problems here, don't spend money in vain!

1. This situation generally appears in the model of mechanical hydraulic power steering, which is a very common way of steering power in the past, referred to as HPS in English, with mature and reliable technology and low cost. This type of steering power assist converts a part of the engine's power output into hydraulic pump pressure, which exerts auxiliary force on the steering system to steer the tires. When the square loss pure to Bikong filial piety disc is not rotated, the pressure in the chamber on both sides of the piston is the same and is in a balanced state.

When the steering wheel rotates, the mechanical control valve connected to the steering column will be opened or closed accordingly, one side of the oil will no longer pass through the hydraulic cylinder and directly flow back to the oil storage tank, the other side of the oil continues to be injected into the hydraulic cylinder, the pressure difference between the two sides of the piston will be pushed under the action of the hydraulic force, and then produce auxiliary force, at this time we will feel that the steering wheel is not so laborious.

2. The steering pump drives the belt to slip. The steering pump is driven by a belt, and if the friction between the belt and the pulley is too small, the belt will slip on the pulley, and there will be a squeaky sound at this time. It may be caused by loose belt adjustment, excessive wear of the grooves of the pulley, or the new belt does not fit well with the old pulley.

A simple way to tell is to pour a little water on the belt when there is a loud manuscript, and if the sound goes away, it means that the belt is slipping. At this time, first adjust the tension of the belt, if there is still a sound after adjustment, you can use it for a period of time to make the belt and the pulley fully match and then see if it is still ringing, if it is still ringing, you have to replace the pulley.

What to do if the steering wheel of the car is abnormal.

1. The sound of rebounding the clip after the turn signal.

2. The sound of the dust jacket of the direction column.

Whether you are in place or driving as long as you hit the steering wheel, you will hear the sound coming from under the steering wheel, you should check the steering post dust jacket, once the steering post dust jacket lacks lubrication, it will produce a dry friction sound, you just need to apply some butter in the dust jacket This sound will disappear.

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.

Millions of car purchase subsidies.

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 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.

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.
