The steering wheel will vibrate slightly after the car is ignited.

The steering wheel will vibrate slightly after the car is ignited. In China, almost many people buy cars, so buying a car is very important. But buying a car also requires a lot of good car habits, because our car is easily damaged. So what about the slight vibration of the steering wheel after the car caught fire?

The steering wheel will vibrate slightly after the car is ignited. 1 The reason why the car vibrates just after starting the steering wheel is that the engine or gearbox foot pad is aging and cracked; There is motion interference between engine and steering gear; The steering belt of the mechanical steering system is too loose, resulting in slipping; When the steering transmission system is loose and the gap is too large, jitter and abnormal noise will occur;

Excessive braking force causes the brake disc and brake pad to overheat, and the steering wheel will shake due to cold deformation. Steering wheel is a kind of wheel-shaped device to control the driving direction of cars, ships, planes and so on. The function of the steering wheel is to convert the driver's force acting on the edge of the steering wheel into torque and transmit it to the steering shaft, which is mainly composed of skeleton, foam and mounting buttons or screw holes corresponding to the main driving airbag DAB.

First, if the car starts cold, the jitter is normal, which is a kind of protection for the car. The car will be normal naturally after preheating. After all, it is impossible to reach the ideal state at low temperature just after getting on the bus, but if it shakes for dozens of minutes, it may be caused by the damage and aging of the engine horn glue. Please go to the 4s shop or professional repair shop as soon as possible to troubleshoot and replace parts.

Second, when the car is driving between 80 km/h and 90 km/h, the steering wheel will shake and return to normal after exceeding 90 km/h.

Treatment method:

1. This situation is mostly caused by tire deformation or vehicle transmission system. Please check whether the positioning angle of the front wheel is misaligned with the toe-in. If it is misaligned, please adjust it.

2. Set the front axle for trial rotation, and check the static balance of the wheel and whether the tire is deformed too much. If the wheel is deformed too much, replace the wheel.

Third, it is normal for vehicles to drive on flat roads, but the steering wheel will shake when encountering bumpy roads.

Solution: When the car is driving, the tire wears irregularly due to the loose wear of the pull rod ball head or the rubber sleeve falling off at the joint. It should be sent to a 4S shop or a professional repair shop to check and replace the damaged parts.

Fourth, when the speed is 30 to 40 kilometers per hour, the car body has a sense of shaking.

Solution: This situation is caused by tire deformation, so just replace the tire.

5. When driving at high speed, the steering wheel suddenly shakes when stepping on the brakes.

Solution: Excessive braking force and frequency may cause the brake disc and brake pad to overheat, deform when it is cold, and cause the steering wheel to shake. Generally, replacing the brake disc and brake pad can solve the symptoms.

6. Body vibration at high speed.

Solution: Because the transmission shaft is deformed or the crosshead of the transmission shaft is loose and rusted due to lack of oil. So every time you do maintenance, try to ask the staff to butter the oiled parts.

The steering wheel is an important part for us to control the direction of the car. If there is a problem with the reverse wheel, please repair it in time to avoid incalculable harm to yourself and others.

The steering wheel will vibrate slightly after the car is ignited. 2. The causes of slight shaking of the steering wheel after the car starts:

1, the most common reason is that the throttle is too dirty or the fuel injector has too much carbon deposit, which seriously causes the car to shake. When there is too much carbon deposit in the engine, the gasoline sprayed by the fuel injection head will be absorbed by the carbon deposit during the cold start, which leads to the lean mixture during the cold start and makes it difficult to start.

In this case, it is easy to run into the car only when the gasoline absorbed by carbon deposits is saturated. After running into the car, the gasoline adsorbed on the carbon deposit will be sucked into the cylinder for combustion by the vacuum suction of the engine, which will make the mixture rich, and the combustible mixture of the engine will be diluted and concentrated, resulting in idling jitter after the cold car starts.

The lower the temperature, the greater the amount of oil required for the start-up of the cold car, and the existence of carbon deposit will affect the smooth start-up of the cold car. Solution: Clean the oil circuit and check whether there is carbon deposit in the idle motor, which should be cleaned.

2. Problems with the ignition system. Check the working conditions of spark plugs, high-voltage lines and ignition coils. The ignition system is not easy to use, and the spark plug is not in good condition, which will also lead to this failure.

3. The aging of engine parts and automobile jitter are also related to the aging of engine feet (also known as claw pads). The engine foot is actually the damping system of the engine. The engine foot is responsible for absorbing slight vibration when the engine is running. If there is something wrong with the engine foot, these vibrations will be transmitted to the steering wheel and cab, causing idling jitter.

Extended data:

Solution:

Check the spark plug for excessive carbon deposition and replace the spark plug. The oil pressure is unstable. If the engine carbon deposit has been cleaned, the throttle valve has been cleaned, the oil pad and spark plug have been replaced, and the body still shakes when idling. It is recommended to go to 4S shop to check whether the fuel supply pressure and intake pressure sensors are normal.

If the oil supply pressure of the oil pump is abnormal, or the value of the intake pressure sensor is wrong and the work is not good, the body will shake. Check the oil pressure and replace parts if necessary.

The steering wheel will vibrate slightly after the car is ignited. If the steering wheel vibrates slightly, there should be no big problem, which is usually caused by engine vibration. Of course, if the owner is not at ease, he can check whether the fixing brackets of the gearbox and the engine are reliable, whether the screws are loose, and whether the supporting feet are reliable. And then deal with it in a targeted manner.

If the car is idling and the steering wheel vibrates, it is necessary to check whether the bolt fixing the steering wheel sensing device is loose or whether there is a problem with the rubber sleeve of the steering wheel transmission device. The steering wheel vibrates when it is killed, accompanied by abnormal sound, which is generally caused by obstacles in the booster oil.

When the steering wheel vibrates during driving and the speed is not very high, the car body will also feel obvious vibration, which is usually caused by factors such as tire friction or aging, so it is necessary to replace the tire in time. If the vehicle speed is about 80-90km/h, the steering wheel vibrates, but if it exceeds 90km/h, there is no problem. Considering that it is caused by the vehicle transmission system, it is necessary to check whether the four-wheel alignment meets the requirements and adjust it in time after dislocation.

Causes of steering wheel jitter when starting a car;

1. Maybe the engine bracket is bad. Check whether the rubber parts in the engine bracket are cracked. If it breaks, it needs to be replaced. Because this part absorbs the vibration of the engine when working, if it is broken, it can't absorb the vibration of the engine, so the steering wheel will shake;

2, cold car steering wheel jitter should be the engine shaking to the steering wheel, it is recommended to check the causes of engine cold car jitter, such as too dirty throttle, too much carbon deposition in the intake air, improper position of the engine claw and so on. Will lead to cold car engine jitter;

3. Excessive braking force and high frequency may lead to overheating and cold deformation of the brake disc and brake pad, causing steering wheel jitter. Generally speaking, the symptoms can be solved after replacing the brake disc and brake pad;
