What causes the steering wheel to shake while the car is moving?

1. If it is only a slight shaking, it may be caused by the resonance of the engine, the owner can check the engine by himself, or the fixed bracket of the gearbox is loose, and whether the screws fixed by the steering machine are loose.

2. When the steering wheel shakes when the car is idling, it is necessary to check whether the rubber sleeve of the transmission device is unusable, and whether the bolts of the transmission device are loose, which may be related to the idle speed and steering machine of the engine.

3. The steering wheel will shake when driving, and you will feel shaking when sitting in the car, because the tire needs to be replaced at this time due to friction, collision or deformation caused by old age when the tire is in use.

4. The steering wheel shakes when braking, which may be caused by braking too hard or too often, and replacing the brake disc and brake pads with new ones can be solved.

1. Direction machine problem:

1) Excessive wear of the ball joint of the tie rod of the steering machine: because it is active, it will wear out after a long time, and there will be subtle angle inaccuracy when steering after the problem, so there will be tire shaking and blurred steering at high speed;

2) Wear of fixed rubber bushing of steering machine: This problem is relatively rare, and it is easy to overhaul, and it only needs to be seen with the naked eye, but once it is worn, it will cause the steering wheel to tremble when driving.

2. There is a problem with the tire:

1) Wheel rim deformation: Generally, the wheel rim will be deformed due to violent impact by external force, and it is more likely to cause problems on some cars with flat tire size, and the wheel hub needs to be replaced;

2) Tire imbalance: Some car owners do not carry out tire dynamic balancing after disassembling and assembling tires, which will cause the high-speed steering wheel to tremble, and generally go to the tire shop to carry out tire dynamic balancing to solve the problem;

3) Tire deformation: Carefully stroke the four tire tread parts of the car with your hands, if you find that the tire tread is jagged, or a tire has a rather abrupt "bulge", it is tire deformation. Sometimes the tire is pierced by nails, which can also cause abnormal noise and heel shake.

3. Deformation of the transmission shaft

1) When the car collides, scratches hard things and damages such as curbs, stones, etc.;

2) The screws of the transmission shaft are seriously loosened or lost, resulting in misalignment;

3) The installation angle of the flange fork and telescopic fork is wrong, and the waist beam bearing and shock absorbing rubber ring of the multi-section drive shaft are damaged;

4) When the transmission pump is twisted and deformed, the feeling of shaking is especially obvious when the car accelerates.

There are many reasons for the vibration of the steering wheel of the car, and the reasons for the road surface are roughly as follows: 1. The free travel of the steering wheel becomes smaller, and the slight vibration caused by the road surface state is directly fed back to the steering wheel, and the free travel of the steering wheel can be adjusted in this case; 2. The toe-in of the car is inaccurate, resulting in the deviation of the car or the vibration of the steering wheel at a certain speed value, which usually appears in the car that has been used for a long time or the front wheel has been strongly impacted, and the four-wheel alignment correction can be made; 3. The steering wheel vibration caused by tire deformation, the tread pattern of poor quality or scrapped tires is dislocated due to shoulder deformation, forming periodic vibration, and the tire can be replaced; 4. The deformation or failure of the components of the automobile suspension system and steering system, such as the loose connection parts of the directional power assist system, the wear of the rubber sleeve of the movable connecting rod, etc., need to be checked in detail to determine the fault before it can be eliminated.

The steering wheel shakes in a certain speed range while the car is moving, and in most cases it is caused by the wheels. Steering wheel shake caused by wheels is mainly divided into the following situationsThere is a problem with the dynamic balance of the wheels.

The most common is the tire dynamic balance problem. When the wheels shake, the vibration is transmitted through the gimbal joint, steering knuckle, steering lever, steering machine, and steering column.

Balancing issues.

The wheels are deformed. The steering wheel is loose.

The free travel of the steering wheel is too large.

The brake disc has an uneven end face.

Drive BAI

When the steering wheel shakes, this situation is very common, and some car owners are driving the car at high speeds.

When the speed of the DAO version reaches 80-100km h or more, you can feel a strong steering wheel shake. In this case, most of the problems occur in the tires of the car, because the uneven distribution of the mass of the whole part of the tire will cause the wheels to rotate at high speed, and there will be a dynamic imbalance state, which will cause the steering wheel of the car to shake seriously while driving. In this case, it is necessary to align and dynamically balance the tires of the car, and in serious cases, the tires must be replaced.

In addition to the tires of the car, there may also be shock absorber failure, frame deformation, excessive meshing clearance of the main and driven gears of the final reducer, etc. If the steering wheel shakes when braking while driving, then it is very likely that the brake force is too strong and too frequent, which may cause the brake disc and brake pads to overheat and deform when cold, causing the steering wheel to shake. Generally, the symptoms can be solved after replacing the brake discs and brake pads.

If the speed of the vehicle is not fast, but the steering wheel shakes, it is possible that the steering belt of the mechanical steering system will slip when the belt is too loose, which will also cause the steering wheel to shake, and there will be shaking and abnormal noise when the steering transmission system is loose and the gap is too large, but this situation is rare.

The main reason for the failure is the increase in carbon deposits in the throttle, intake tract, valve and other parts, which adsorbs some gasoline when the car is cool, and so on to the hot car, these gasoline volatilize, and when the engine idle, it will cause the mixture to be too thick, resulting in the unstable idle speed of the hot car.

Therefore, you should not only check the throttle valve and idle motor, etc., but also check whether there is too much carbon and dirt in the intake tract, if there is too much, it will cause the cross-sectional area of the air channel to change, so that the control unit can not accurately control the amount of idle air intake, resulting in too thick or too thin mixture, so that the combustion is abnormal and causes the engine to shake. At the same time, it is also necessary to check whether the canister is faulty.

It may be a manifestation of poor dynamic balance between the two front wheels of the vehicle, and the downward dynamic balance can be adjusted.

The wheels of the car are a whole body composed of tire version and wheel hub. However, due to manufacturing reasons, it is impossible for the mass distribution of the parts of this whole to be very uniform. When the wheels of the car rotate at high speed, a dynamic imbalance will be formed, resulting in the phenomenon that the wheels of the vehicle shake and the steering wheel vibrates while driving.

In order to avoid this phenomenon or to eliminate the phenomenon that has already occurred, it is necessary to make the wheel correct the balance of each edge part by increasing the counterweight in the dynamic situation. This process of correction is often referred to as dynamic equilibrium. If the dynamic balance of the two front wheels is adjusted or shaken, it may be caused by the loosening of the bearings of the two front wheels or the loosening of the ball head of the bracket.

It is also possible that the front and rear shock absorber support blocks of the engine and gearbox are not normal, and it is recommended to check and repair them.

Car high-speed bai

When driving, DU is most afraid of local earthquakes.

Zhi moves, especially the steering wheel sends dao

There is a small jitter. version of driving this right.

This kind of car, not only afraid of not being able to control the direction of the car, but also worried that the steering wheel is not easy to use, the most anxious and uneasy.

When driving at high speeds, the steering wheel shakes slightly, mostly due to poor dynamic balance of the wheels. Usually, this phenomenon occurs within a certain speed range, and steering wheel shake usually occurs when the speed reaches about 90 kilometers per hour. Below or above this speed, this small jitter can disappear immediately, because at this specific speed, the vibration frequency generated by the poor dynamic balance of the wheels can just resonate with the steering wheel, so the steering wheel shakes at a specific speed.

Adsorb some gasoline when the car is cool, and when the car is hot, the gasoline will volatilize, and the mixture will be too thick when the engine is idling, resulting in unstable idle speed of the hot car. At the same time, it is also necessary to check whether the canister is faulty.

Note! The steering wheel shakes while the car is moving, and it is likely that this is the cause!

The situation of your vehicle, it may be a motor or transmission machine

Foot damage, start.

The machine accumulation DAO carbon is too much, and the engine is in.

If the machine is short of cylinder, the clutch plate is uneven or slippery, because you can't see the actual car, you can't accurately judge the fault, it is recommended that you contact your local 4S shop for inspection and maintenance. If you can't solve the problem, you can feedback your problem through the car quality network.

Causes and solutions for car steering wheel shake.

Note! The steering wheel shakes while the car is moving, and it is likely that this is the cause!

The steering wheel shake in the car is mainly caused by the following reasons: 1. The steering gear bearing is too loose or the steering gear gear transmission pair clearance is too large.

2. The ball joint pins of the main and tie rods are worn loosely and loose.

3. The kingpin and lining pin of the steering knuckle are seriously worn, and the matching gap is too large.

4. The front hub bearing is loose.

5. The front wheel is bent and the rivet is loose.

6. The frame and rim are deformed.

7. The toe-in is too large.

It is enough to rebalance the front tires from the bottom.

Analysis of the causes of car shake:

1. Suspension system problems.

Body shake is also related to the aging of the suspension system. It is mainly responsible for filtering out the shake of the engine when it is running, and if there is a problem with the suspension, these vibrations will be transmitted directly to the steering wheel and cab, affecting the driving. When the engine is idling, it is easy to cause shaking when the electrical system in the car is turned on.

The engine will increase the load when the electrical appliances are turned on, causing the idle speed to drop, and to compensate for the jitter caused by the idle slip, the engine will automatically increase the speed by partially. So, when the electrical system, especially the air conditioner, is turned on, the engine will often shake. This jitter is likely to be caused by the aging of the shock absorber and needs to be replaced in time.

2. Tire problems.

For tires, the tire must be balanced once when the car is replaced with new tires and new steel rims, otherwise the steering wheel will be prone to shake when the counterweight is uneven. If you find that the tire weight is not equal, you need to add lead to the inside of the rim to average the weight of the tires on both sides. Whether it is a general steel ring or a lightweight aluminum ring, it may deform or crack when subjected to a certain external force.

Deformation of the rim can cause shaking when driving, uneven weight of the rim can also cause shaking when driving, and incorrect angle of the rim can also cause shaking when driving.

3. Throttle problems.

The most common cause of car shake may be a dirty throttle valve and excessive carbon build-up in the fuel injector. After the car travels for a period of kilometers, the throttle valve will be too dirty to cause the throttle to close loosely or the idle motor to stagnate, resulting in the engine idling speed is too high, and the carbon deposits generated by the engine in this process will also cause the vehicle to shake, especially when starting the vehicle, the engine will shake more than normal, and even sometimes there will be a phenomenon that can not be started at one time. Therefore, when the body shakes, the first thing to do is to check the throttle and fuel injectors.

If you find that the throttle valve is too dirty or the fuel injector has too much carbon deposit, you should clean it with fuel injector cleaner or throttle cleaner in time.

4. The oil pressure is unstable.

If you still find that the body shakes after these are finished, it is recommended that you go to the repair shop to check whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is not normal, the intake pressure sensor is wrong and improper work will cause the body to shake.

There are many reasons for the vibration of the steering wheel of the car, and the reasons for the road surface are roughly as follows: 1. The free travel of the steering wheel becomes smaller, and the slight vibration caused by the road surface state is directly fed back to the steering wheel, and the free travel of the steering wheel can be adjusted in this case; 2. The toe-in of the car is inaccurate, resulting in the deviation of the car or the vibration of the steering wheel at a certain speed value, which usually appears in the car that has been used for a long time or the front wheel has been strongly impacted, and the four-wheel alignment correction can be made; 3. The steering wheel vibration caused by tire deformation, the tread pattern of poor quality or scrapped tires is dislocated due to shoulder deformation, forming periodic vibration, and the tire can be replaced; 4. The deformation or failure of the components of the automobile suspension system and steering system, such as the loose connection parts of the directional power assist system, the wear of the rubber sleeve of the movable connecting rod, etc., need to be checked in detail to determine the fault before it can be eliminated.

Look at how to shake, the general horizontal (left and right) shake should be a problem of dynamic balance or tires, adjust the tires, replace them if necessary, do the dynamic balance from the new, do it well, if you deviate from the 4-wheel alignment.

In addition, the engine and transmission claw pads (also called brackets) should also be checked for aging and breakage.

There are several reasons for this phenomenon.

1. Toe-in: When the car is driving, the steering tie rod and the steering tie rod are deformed due to collision, and the ball joints are worn loosely or the tires are worn irregularly.

then, make the toe-in increase or decrease.

2. Poor wheel dynamic balance: the loss and deformation of the original wheel dynamic balance lead block causes the car to swing and the steering wheel shakes when driving at high speed.

3. The ball joint of the transverse thrust rod is loose or the bracket is loose, resulting in unstable driving.

Fourth, the wheel bearing is loose and the ball joint of the left and right steering joints is seriously worn, so that the front wheel positioning is inaccurate.

5. When the car is driving, the stability is also affected due to damage to the steering shock absorber, oil leakage, or deformation of the front hanging spring.

In the repair process, we according to different situations, the steering of the vehicle such as the steering wheel of the open volume, toe, front wheel alignment,

The wheel dynamic balance, suspension springs and steering shock absorbers are carefully checked, adjusted, repaired and replaced with parts to restore the original stability.

Qualitative to ensure driving safety.
