What should I do if the steering wheel is mistracked? What s going on with the steering wheel of the

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

If the vehicle is able to keep going straight for a while after releasing the steering wheel, the vehicle will have no problemIt's caused by the steering wheel being off-track. If the vehicle is mistracked, check the tire pressure and then look at the wheel alignment. Look at whether the gap between the steering machines is large.

If the free clearance of the steering wheel is too large, the steering wheel will automatically deviate.

Vehicle malfunction: If the car still deviates when the body is right and the steering wheel is also right, it may be due to a body failure. This is more common in older test vehicles.

Steering wheel deviation fault cause:

1. The positioning elasticity between the control valve and the valve sleeve in the steering gear is reduced or broken.

2. There is a positioning spring between the control valve and the valve sleeve, so that the valve sleeve and the control valve are in a neutral position, so that the vehicle can keep running in a straight line. When the elasticity of the spring blade is weakened or broken, it is easy to deflect the valve sleeve and the control valve, causing the unilateral cylinder to move, causing the vehicle to deviate.

3. Most of the deviation caused by the reduction of the elasticity of the spring blade is biased to one side, and one end of the return spring is broken, and the vehicle deviation is left and right.

The way to check is as:

Position the car on a straight road to make a mark, and then gently swing the steering wheel, taking care not to exceed 8° to the left and right to see how it returns. In low-speed driving, repeat the above actions, if you can't return to the middle position, and there is no other reason to cause deviation, it may be that the return spring is broken or the elasticity is reduced, and the accessories should be replaced.

For vehicles that have been used for too long, due to the long-term torsional action of the pin column in the valve sleeve and the control valve, especially the load of the vehicle in driving, the steering gear bears high back pressure, resulting in a large torsional force on the pin pin. If it is used for too long, it is easy to cause the pin to bend and deform, so that the valve sleeve and the control valve can not be in the "neutral" position, and it can also cause the car to deviate.

Too much difference in tire pressure: Too much difference in tire pressure between the two front wheels can also cause mistracking. This phenomenon is mostly obvious when heavy load, and the pressure difference between the two wheels does not exceed under normal circumstances.

Car steering wheel deviation, maintenance precautions:

When the car is driving in a straight line and the steering wheel is running to one side, the first thing you should do is check whether the hydraulic oil is dirty. If a new car or overhauled vehicle is not strictly enforced, and the oil change regulations for legal maintenance are followed, the oil will be dirty.

Under normal air pressure, first check whether the tire wear is uniform, and then check whether the lower swing arm, ball joint, ball cage and other parts are normal. You can also adjust the steering lever, when the steering lever is long and short on one side, it will cause the car to deviate on the long side.

The steering lever is an important part of the steering mechanism of the automobile, which directly affects the stability of the car operation, the safety of operation, and the service life of the tire. Secondly, check the directional stabilizer bar and steering machine, the steering machine is mechanical, it may wear too much, or the gap between the steering wheel tie rods is large, so it should be checked before positioning. If there is no damage to the parts, it means that the clearance of your steering machine is too large, and the steering wheel can be corrected by adjusting the toe-in, and it can also be replaced if the steering machine is problematic.

When the buffer on both sides of the deformation of the shock absorber spring is inconsistent, it will also lead to deviation, and the quality of the shock absorber spring can be judged by pressing or comparing it after clearing and dismantling. When the shock absorber before the nuclear fails, the two suspensions, one high and one low, are unevenly stressed during the vehicle, resulting in deviation. The absorption of the shock absorber can be detected by a special testing tester to judge the quality of the shock absorber, such as unconditionally detachable, and judged by stretching.

If the steering wheel is serious, it is necessary to carry out 4-wheel alignment, which can solve the problem of deviation well, if not, you need to replace a bunch of things, specifically ask the repair personnel: 1. When the vehicle leaves the factory, the positioning angle of its suspension system is pre-set according to the design requirements, and these positioning angles are used to ensure the comfort and safety of vehicle driving; 2. However, because the vehicle is sold and driven for a period of time, these positioning angles will change due to traffic accidents, violent bumps caused by uneven road potholes, wear and tear of chassis parts, replacement of chassis parts, replacement of tires, etc.; 3. Once there is a change, it will cause abnormal wear and tear, and in serious cases, there will be deviation.

Causes and solutions for steering wheel deviation:

1.Steering wheel misalignment is caused by different steering wheel tire pressures on both sides of the vehicle. It is necessary to adjust the tire pressure of the steering wheel on both sides of the vehicle so that it is consistent.

2.The tread pattern of the steering wheel of the vehicle is different, and the depth is also different. When the vehicle is moving, the steering wheel will lose control. It can be maintained in the 4S shop.

3.The deformation of the front shock absorber springs of the vehicle can be judged by comparison after pressing or dismantling. You can also go to the car 4S shop and replace it according to the situation.

4.If the front shock absorber fails, the quality of the shock absorber can be judged by a special tester to detect the absorption of the shock absorber, and it can be disassembled and replaced.

5.The vehicle's four-wheel alignment is inaccurate. Owners are advised to recalibrate their vehicles.

6.If the vehicle's power steering system fails, the owner needs to check and repair the vehicle's power steering system in time.

7.If the braking system fails, it is necessary to check the braking system in time.

8.Excessive wear and tear of vehicle chassis parts with abnormal clearances. It is necessary to send it for repair.

9.If the front wheel alignment angle is out of balance and the toe is too large, you can go to a 4S store to deal with it.

10.Suspension system failure. Problems with the original design, such as the interference of movement between the guide rods of the suspension and the tie rods of the steering system, can affect the deviation of the vehicle. The former is caused by errors in manufacturing and adjustment, and the latter is caused by the original design.

1. The overall deformation of the vehicle, the wheelbase difference between the two sides is too large, beyond the maximum allowable range. It can be measured with a tape measure. If it is out of range, it must be corrected with a correction table. Millions of car purchase subsidies.

The causes and solutions of car deviation are summarized as follows.

1. Cause of failure: The air pressure of the tires on both sides is not equal.

Exclude: Adjust tire pressure.

2. Cause of failure: The front brake is not completely separated.

Troubleshooting: Repair the front brake.

3. Cause of failure: failure of the front spring.

Solution: Replace the front spring.

4. Cause of failure: The position of the front wheels on both sides is different.

Elimination method: Adjust the alignment of the front wheels on both sides to make the data consistent.

5. Cause of failure: the front wheel bearing is too tight.

Troubleshooting: Adjust the front wheel bearings.

6. Cause of failure: deformation of the bottom of the body or frame.

Troubleshooting: Correct or replace the body or frame.

7. Cause of failure: shock absorber failure.

Troubleshooting: Replace shock absorbers.

What causes the vehicle to deviate to the left

The car deviation should first look at the front suspension, whether the ball joint arm is loose, whether the tire tread is seriously worn, wear deviation, do a four-wheel alignment adjustment, another situation If the vehicle has an accident, it is necessary to measure the difference between the left and right front and rear wheel tracks, if too much will also run off, the vehicle deviation at high speed must have hidden dangers.

If the direction of the car deviates, if it is a normal vehicle that has not had a major accident, it will generally be caused by the following reasons:

1. The left and right tire pressure is inconsistent, which is the most common reason for the steering wheel deviation, under normal circumstances, the front and rear tire pressure is generally on the left and right, and the front tire may be slightly lower. In the process of time driving on the car, the ground contact area and force of the left and right tires must be uneven, and the tire pressure will be inconsistent after a long time, and the direction of the car will also be biased to the side of the low tire pressure.

Solution: Just make up the tire pressure.

2. The inconsistency of the left and right tread wear is similar to Article 1, and the inconsistency of the car steering and rolling the road surface will also cause differences in the wear of the tires. However, when the tread on one side is worn too much, its diameter will be smaller, and the direction of travel will also be biased to this side.

Solution: In addition to changing the tire, if it is a front tire, it can be swapped with the rear tire on the same side.

3. The shock absorber springs have different degrees of metal fatigue, that is to say, the strokes of the springs on both sides are inconsistent, one high and one low make the body unlevel, resulting in the vehicle deviation. If you still deviate after making the first two adjustments, this may be the reason.

4. Brake system failure, which is often referred to as bias brake. If the brake cylinder on one side is not working properly, the brake pad return is not complete enough, and the wheels on this side are kept braking during driving, which will also cause the vehicle to deviate.

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 steering wheel is not turned, the pressure in the chambers on both sides of the piston is the same and it is in equilibrium.

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 noise, if the noise 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.

The problem of steering wheel deviation to one side can not be blindly done four-wheel alignment, and different measures should be taken according to different situations: 1. If the steering wheel deviates left or right, but when driving at high speed on a straight road, keep the steering wheel left or right, and the steering wheel will not deviate when you let go of the steering wheel. In this case, it is not a mistracking, but a relative rotation of the steering wheel and steering column.

The steering wheel deviation is mainly due to the failure of the braking system, the change of four-wheel alignment data, the uneven tire pressure on both sides, and chassis problems.

1. The braking system is faulty

If braking occurs, the car will deviate, this may be a problem with the braking system, the brake pump of the tire on the side of the deviation has a problem, resulting in the brake pads can not return normally, the equivalent wheel has been in a slight braking state, resulting in running deviation, the solution is to check the braking system in time.

2. Changes in four-wheel alignment data

The change of 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 store in time to do a four-wheel alignment.

3. The tire pressure on both sides is unbalanced

If the tire pressure on both sides is unbalanced, on a flat road surface, the left and right are high and low, and the vehicle will naturally deviate to the side of the air loss, the solution is to check whether the tire pressure on both sides is normal, and if the air is missing, then pump and fill.

4. Chassis problems

The change of the main components may be due to the wear and aging caused by daily driving, or it may be due to the accident caused by the deformation of the frame, the aging problem is easy to say, if it is due to the deformation of the body caused by the accident, the deviation caused by the damage to the frame, etc., it is more serious, and it is necessary to replace the parts in a large area or even the 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.

The steering wheel is always not moving. Workaround:1. Make sure that the air pressure of all four tires is exactly the same. 2.Use the same type of tires. 3.Wheel alignment. 4.Check the suspension and steering.

1.Measure tire pressure.

From a practical point of view, the most common factor causing car deviation is the deviation caused by different tire pressures. It's simple. It can be solved by measuring the tire pressure at the maintenance mechanism to ensure that the tire pressure of each tire is consistent.

Of course, in addition to the tire pressure, the different degrees of wear of the tread pattern can also cause deviations, so it is necessary to change the tire position or change the tire.

2.Wheel alignment.

This measure is also the most common method of correcting deviations. Compared to tire pressure measurement, the cost of four-wheel alignment is higher, and the owner can balance the tire pressure first and then see the effect. If the tire pressure is still off, wheel alignment is still required.

3.Check the suspension.

If the wheel alignment does not work, the suspension of the vehicle should be considered at this point. In general, if there is a problem with the design of the car's suspension, it is easy to deviate. In addition, during use, the suspension is damaged, deformed, displaced, etc. Prone to deviations.

Check the steering. The steering system can wear out for a long time, resulting in too much clearance between connectors, or parts such as bearings that become loose, causing the car to not follow its normal trajectory, resulting in mistracking.

It should be reminded here that if it is a deviation caused by suspension, the owner must replace the left and right sides together when replacing the spring, rather than only replacing the spring with problems on one side, so as to ensure that there will be no new deviation.
