The car ran to about 100 yards and the steering wheel shook, what is the reason?

1. ThrottleWhen we step on the accelerator, the vehicle has some shaking, and most of the time it is a problem with the throttle. When carbon deposits or other pollutants are adsorbed on the throttle, it will cause the amount of air inhaled by the engine to be out of proportion to the amount of oil sprayed out of the fuel injector, resulting in insufficient fuel when the engine is working, resulting in body shake. In this case, you can go to the repair shop to clean the throttle.

Second, the spark plug spark plug as the ignition device in the engine, if there is a problem with the spark plug, then there is no ignition of the mixed gas in the cylinder, and the cylinder will not work, so that the power of the vehicle will decline, which is what we call the lack of cylinder. If you drive a lot, when the vehicle feels a strong shake and the vehicle has no power, and this shake exists from the start of the vehicle to the shutdown, then most of the spark plug is a problem. At this time, it is necessary to check whether the spark plug in a cylinder is broken.

The spark plug is a consumable, for the car owner, the spark plug should be checked during regular maintenance, and the spark plug should be replaced in time if the spark plug is almost depleted.

Third, the rubber ball cover itself is a consumable part, the main role in the body is also to play the role of shock absorption and dustproof, generally installed in the connection between the engine and other components, when the rubber sleeve is damaged, when stepping on the brakes, you will feel that the vehicle has shake, release the brake shake and disappear, in this case you will have to check the ball cover. Fourth, brake pads, as an important part of vehicle braking, play a vital role in the safety of vehicle driving. As long as you drive, you will use the brakes, so the longer the time, the more the brake pads are worn.

When the brake pads are worn more, when the brakes are applied, the braking effect will be reduced, the body will shake, and there will be some sizzling sound at the wheels when braking. Then it's time to check the brake pads and replace them in time. For the sake of our driving safety, we must check the vehicle in time and replace the damaged parts.

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.

This is a resonance phenomenon, theoretically every car has a resonance point, there are high and low, which is related to the engine, road surface, frame, etc., the situation is very complicated, and the maintenance is very difficult.

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.

Perhaps the following points are affected.

a.Whether the triangular arm and ball head of the car are aged and loose.

b. Whether the front wheel has been hit and the tire is out of circle.

c. Slight jitter is a normal phenomenon (the resonance point of your car is exactly about 80 yards, and whether the dynamic balance correction is accurate.)

High-speed steering wheel shake:

1. The dynamic balance of the two front wheels is not caused, so it is recommended to adjust the dynamic balance data of the next two front wheels.

2. The loosening of the lever ball joint of the steering machine will also cause the steering wheel to shake at high speed.

Solution: After each tire replacement, you need to do the dynamic balance of the tire, and you can check whether the tie rod ball joint of the lower direction machine is loose during maintenance.

The reasons why the steering wheel shakes when the car runs to 100 yards are: 1. The balance weight falls off or is damaged; 2. The difference between the four tire pressures is large; 3. The deviation angle of four-wheel alignment is large; 4. Shock absorber failure; 5. The large frame of the car silver is deformed; 6. The meshing gap of the driven gear is too large. The solution to the steering wheel shake when the car runs to 100 yards is:

1. Check and adjust the tire pressure; 2. Check the dynamic balance and correct the centripetal force of the tire; 3. Check the four-wheel positioning front liquid vertical; 4. Check and repair the chassis, braking system, and engine suspension. The precautions for high-speed driving are: 1. Fasten your seat belt; 2. The driver should avoid receiving calls**; 3. It is forbidden to throw items outside the car.

Analysis of the causes of car shake:

1. Cold start jitter.

First of all, starting from the cold start, the main reason for the cold start body shaking is that the fuel combustion is insufficient, resulting in insufficient power of the car. The ignition energy is low, and when starting, especially when the temperature of the fuel and lubricating oil is low, more oil is required to meet the power. Over time, the pole gap of the spark plug gradually increases, resulting in a decrease in ignition energy and poor fuel atomization, which leads to the shaking of the body.

In addition, the ignition energy can also be reduced due to the aging of the ignition coil, the aging of the high-voltage wire of the spark plug, or the leakage of electricity.

2. 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.

3. 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.

4. 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.

5. 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.
