Do you know why the steering wheel shakes? What is the cause of jitter?

Some car owners will find that the steering wheel suddenly shakes while driving, which is one of the most common faults in the car. And sometimes the amplitude of the jitter is relatively large, and sometimes the amplitude of the jitter is relatively small. In fact, this is caused by some parts of the car being loose or malfunctioning.

Phenomenon 1: The steering wheel shakes during high-speed driving. It may be the power imbalance of the tires, because the power imbalance of the wheels will cause the car to jump when driving, and this beating will be transmitted to the steering wheel through the steering transmission parts, causing the steering wheel to shake.

Phenomenon 2: The steering wheel shakes when the car passes over uneven roads. It may be that the tires have been used for too long and the wear of the tires has reached the maximum, and the tires need to be replaced.

It may also be caused by a loose rod ball joint or a rubber sleeve at the joint falling off, so you need to replace the car parts in time.

Phenomenon 3: The steering wheel shakes when braking sharply. When driving at high speeds, slamming on the brakes, or stepping on the brakes frequently, makes the temperature of the brake disc and brake pads too high, resulting in deformation. It can be solved by replacing the brake disc brake pads.

Phenomenon 4: Idle jitter. It may be that the conveyor sleeve is aging or loose, and the bolts of the transmission device are not loose. Including engine carbon deposits, steering, and engine mounts, there may be problems that cause idle jitter.

Phenomenon 5: The steering wheel shakes when driving at low speeds. Due to the lack of good maintenance of the car, when driving, many parts are aging, or some deformation, and the car will collide, rub, and shake.

Phenomenon 5: After a major accident, the steering wheel will shake even if the car is repaired. Most of this happens in second-hand cars, if the second-hand car has had a major accident before, it is possible that its chassis will be deformed, which must be paid attention to.

Therefore, it is important to check the condition of the vehicle well before buying a used car.

Therefore, steering wheel shaking is more common, but it should not be ignored, and once it appears, it is necessary to go to the repair shop to check to make sure that the steering wheel is no longer shaking.

I know why the steering wheel is shaking, because when driving, there is a certain problem with the engine, so the steering wheel is shaking, or it may be because we use the wrong oil, or the road is too bumpy.

I know that it may be because of the speed, it may be because the tire is deformed, it may be that the tie rod ball joint is worn, it may be because the tire is old, it may be that the brakes are slammed.

I know. The power imbalance of tires, driving at low speeds, uneven road surfaces, sudden braking, and idle shaking can all cause shaking.

I know. The road surface is uneven, the car is malfunctioning, the steering wheel screws are loose, the car tires are unbalanced, and the speed of driving is too fast.

Because of the shaking caused by the imbalance of the power of the tire, if the tire is unbalanced, it will cause the parts inside to shake, which is the fundamental cause of the shaking.

The steering wheel shakes when the car is idling, which is very common, and some car owners can feel a strong steering wheel shake when driving the car at high speeds, when the speed reaches 80-100km h or more. 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.

Why does a car steering wheel shake?

Try balancing the four wheels.

There are many reasons for a car steering wheel to shake: toe-in failure, loss of wheel dynamic balance lead, loose push rod, loose wheel bearings, damage to steering shock absorbers, etc.

The steering wheel is shaking inexplicably, which may be a problem in these aspects.

1. Abnormal tire pressure

When the tire pressure of the wheel is abnormal, especially when the tire posture pressure is too high, due to the decrease of the shock absorption effect of the tire, the unevenness of the road surface is transmitted to the steering wheel through the tire, resulting in the wheel rubber shock.

2. The dynamic balance weight is lost

On the hub, there will be inlaid or pasted dynamically balanced lead blocks. These lead blocks are intended to compensate for the ups and downs of the wheel balance. Ensure that the wheel hub will not vibrate when running at high speed.

If these lead blocks are missing, the dynamic balance will be disrupted, resulting in steering wheel shaking at high speeds.

3. The hub bolt is loose

When the hub bolts are loosened, there will be a gap between the wheel and the hub axle. Even the slightest loosening can cause the body and steering wheel to shake at high speeds.

4. Often enter the big pit

Some car owners do not pay attention to driving, and there are often high-speed through the big potholes and big bags, although there is nothing unusual at the time, but it is likely to cause the wheel deformation invisibly. The dynamic balance state is disrupted, and the steering wheel shakes.

How to prevent steering wheel shake?

1. When going to the roadbed, it is best to use bricks to pave the mat.

2. Avoid high-speed pit bags, speed bumps and other road sections.

3. Check the tire pressure regularly to maintain the correct tire pressure.

4. Check the tire bolts regularly to avoid loosening.

Why does a car steering wheel shake?

The causes of jitter vary depending on the conditions of use. If there is a shivering shaking of the steering wheel in high-speed driving and smooth neutral gear, smooth road, check the tires, steel rims, and drive shafts.

When you press the brake pedal, it will swing left and right, and check whether there is a gap between the connecting parts of the steering system, such as the steering ball joint, tie rod, and steering machine. If there is a gap and driving on uneven roads, not only will the steering wheel swing, but it will also appear.

Clanging noise.

If the steering wheel shakes when you press the brake pedal, and the body shakes at the same time, check whether the pressure bearing seat on the upper part of the shock absorber is deformed and aged. If the steering wheel shakes and the brake pedal pulsates, check whether the brake disc is deflecting or scooping. If there is only a top foot, the vehicle has the feeling of jumping up and down, it may be that the tire specifications are different. ‘

Analysis of the original circle of automobile jitter:

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 car must be balanced once when replacing 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 too high idle speed, and the carbon deposit generated by the engine in the 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.

Causes and solutions for car steering wheel shake.

1. When the speed of the car is between 80 kilometers and 90 kilometers per hour, the steering wheel shakes and returns to normal when the speed exceeds 90 kilometers per hour. Most of this situation is caused by tire deformation or vehicle transmission system, and it is necessary to check whether the positioning angles of the front wheel and the toe meet the requirements, and if it is inaccurate, it should be adjusted; Set up the front axle to test the wheels, check the static balance of the wheels and whether the tires are too deformed, if the deformation should be replaced.

2. When the speed of the vehicle is 30 to 40 kilometers per hour, the body has a sense of shaking, such as the feeling of riding a boat. This situation is mostly caused by the deformation of the tire due to rubbing, collision or aging during daily use, and the tire can be replaced.

What are the causes of steering wheel shake? Steering wheel shake is a common fault, which is prone to occur when driving to 50,000 or 70,000 kilometers. The shaking of the steering wheel will cause the resonance of the body and lead to unsafe driving, so there are certain requirements for the steering system, suspension system and dynamic balance system of the steering wheel.

I once repaired a car that was damaged because the right front wheel fell into a pit. Upon inspection, it was found that the wheel hub had been deformed. The fault of the car is that the steering wheel shakes when the speed is exceeded, and the shake varies with the speed of the vehicle.

After repairing and replacing the new wheels, the wheel dynamic balancing and four-wheel alignment were done, and the tire pressure was adjusted to about 220kpa, and the fault was solved. Therefore, there are many reasons for steering wheel shake. Here are a few common causes of failure.

The steering wheel is connected with the upper end of the steering shaft by bolting, and the middle of the steering wheel is provided with the safety suspect limb airbag horn, and the front and rear ends of the steering shaft are connected with universal joint respectively, and the lower end of universal joint is connected with steering machine. The function of the universal joint is to make the steering wheel and steering shaft parts can be reasonably arranged to achieve 360 degree rotation and bending.

We know that when driving, the steering wheel is parallel to the instrument panel, and because the steering shaft is relatively long, the shaft cannot be vertically erected on the connecting steering machine. The direction machine is installed with a rack and pinion mechanism, and the gear above is connected to the universal joint, the rack is a long ruler, the shape is a cylinder with teeth, when we play the steering wheel, the rotation torque passes through the gear, and the gear drives the rack to move left and right, the two ends of the rack are connected to the tie rod, and the steering knuckle is driven to drive the wheel to rotate through the steering tie rod.

The hydraulic power steering system changes the oil pressure of the power cylinder in the steering machine through the action of the power pump to increase the force on the steering wheel. The electric power assist system is equipped with a power motor in the direction of the steering machine or steering shaft, and the power assist is realized through the torsion reduction effect of the motor. The structure of the steering system can be referred to in the diagram below, which lists the components of the system.

Steering wheel shaking when driving, this situation is very common, some car owners can feel the steering wheel shake strongly when driving at high speeds, the speed of the vehicle is more than 80-100km h. This situation is mostly a problem of automobile tires, because the uneven distribution of the mass of each part of the tire will cause the wheel to rotate at high speed, dynamic imbalance, and cause serious shaking of the steering wheel of the car. In this case, it is necessary to align and dynamically balance the tires of the car, and in serious cases, the tires need to be replaced.

If the speed of the car is not fast, but the steering wheel is shaking, it may be that the steering belt of the mechanical steering system is too loose and the slippage phenomenon will also cause the steering wheel to shake, and the steering transmission system is loose, and there is shaking and abnormal sound when the gap is too large, but this situation is very rare. This situation is mostly caused by tire deformation or vehicle transmission system, to check whether the positioning angle of the front wheel and the toe meets the requirements, if it is not aligned, it should be adjusted; Set up the front axle to test the wheel, check the static balance of the wheel and whether the tire is too deformed, if so, it should be replaced.

When the vehicle is driving at high speeds, the steering wheel will shake. The speed is around 100, and the steering wheel shakes badly. It may be due to the misalignment of the wheels, the tire balance falling off, and the uneven distribution of the tire mass at high speeds, which causes the wheel to shake, and the shake disappears immediately after reaching a certain speed.

If the jitter only occurs when the brakes are in use, check for wobble of the brake drum and disc on the brake-related wheels, otherwise, check for wobble on all wheels. If one wheel swings too much, it is necessary to repair or replace the brake disc.
