The car is shaking at a high speed of 120 or more, what asks

It may be because the wheels have a reduced balance ability after driving at high speed, and dynamic balancing can be done.

The wheels of a car are made up of tires and hubs. 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.

Hello! The driving steering wheel shakes the two front wheel tires to do the dynamic balance, and the body or seat shake is the two rear wheels to do the dynamic balance! Still shaking, adjusting the front and rear tires or deforming the tires!

The body of the driving gas pedal is shaking, and the accelerator is not shaken when you lose the accelerator, most of the drive shafts are broken! Changing tires must be dynamically balanced, otherwise it may cause the vehicle to shake, and the four-wheel alignment can not be done! If the vehicle is misaligned or the steering wheel is crooked or the tires are abnormally worn, you need to do a four-wheel alignment!

I hope it can help you, the car master wishes you a happy car, thank you for your support, if you have any questions, please ask. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

I believe that many car owners have driven on the high-speed road, and many drivers pay special attention to the driving safety of the car due to the high speed in the high-speed road. When the speed of the car reaches 120 yards, the body of the car shakes very obviously, and this is caused by two reasons, the first reason is because of the different tire pressure of the car; The second reason is a malfunction in the suspension system of the car's tires. Both of these reasons can cause the car to shake when driving on the highway.

1. The tire pressure of the car is different, which leads to the occurrence of this phenomenon.

The tire pressure of car tires is very important for cars, especially on highways, car owners must focus on checking the tire pressure of cars. When the tire pressure of the car is different on both sides, then the car driving on the highway will cause the car to shake, because the tire pressure on both sides of the car is inconsistent, it will cause the force of the tires on both sides to be different, which will cause the problem of body shaking. At the same time, the tire pressure problem also affects the safety of the car, if the tire pressure is too large, it will not lead to a tire puncture, and it is very dangerous to drive on the highway car tire puncture.

Second, the failure of the automobile suspension system will also lead to this kind of problems.

The suspension system of the car is very important for the car, and the quality of the suspension system of the car directly affects the comfort of the driver. When the car is driving more than 120 yards on the highway, if there is a problem with the suspension system of the car, such as the bearing position in the suspension system is seriously worn, and the rubber sleeve is seriously aged, these problems will lead to the phenomenon of body shaking. <>

3. Summary. In general, when the speed reaches 120 yards, the owner feels that the body shakes significantly, then it is caused by the inconsistent tire pressure on both sides of the car's tires and the failure of the car's suspension system. Therefore, at this time, the owner must reduce the speed of the car to prevent traffic safety accidents caused by car tire punctures, and then go to a professional auto repair shop for targeted inspection and maintenance.

At that time, when the owner was driving on the high-speed road, he must check the tire pressure of the car and the condition of the car in advance to ensure the safety of the car owner during the trip. <>

This is a relatively normal phenomenon, when the wheels of a car rotate at high speed, it will form an unbalanced state, resulting in the car shaking in the process of driving, of course, it may also be that your car has other parts of the fault, you should go to a professional 4S shop for inspection, if not, you don't need to care too much.

The shock absorber is not working well and cannot absorb the vibration well, so the shock absorber can be checked and repaired or replaced if it fails.

This is mainly due to the air pressure difference between the tires, which causes the car to shake when the wheels have different abilities to absorb vibrations.

If your car is driven to 120 miles, the body shakes and there is usually a problem with the dynamic balance. Wait until you get home and do a balancing, and the problem will be solved.

Causes of car jitter:

1. If the carbon deposit in the engine cylinder is serious, it will cause spark plug blockage and valve blockage, which will directly lead to the shaking of the car when idling. If the acceleration of the car is not as good as before, and the shaking is very persistent, then you can consider cleaning the engine cylinder.

2. The failure of the oil supply system and the unstable oil pressure can easily cause the concentration of the mixed gas to be unstable, which will not only cause jitter but also cause the phenomenon of unstable idling. You can first consider replacing the gasoline filter, after all, the filter element may be clogged after a long time, and then check the oil pressure that does not pass through the gasoline filter, if it is not normal, it may be a problem with the oil pump.

Vehicle maintenance: pay attention to the speed of the car for one and a half minutes when starting from the cold car, so that the car has a period of warm-up time. (At the start, the internal temperature of the engine does not reach the normal operating temperature - the water temperature gauge indicates that 90 degrees is normal.) The car will shake, the engine will be loud, and the tachometer will be slightly higher - normal refers to 600 to 900 rpm.

If you start in such a situation, it is easy to have carbon deposits in the engine, because the combustion of the engine is not sufficient at low temperatures).

The car drove to 120 and was driving at high speed. The car starts to tremble at 120 at high speed, which can be analyzed from the following two dimensions:1

First, with the increase of vehicle speed, the oscillation becomes stronger. 2.Second, when oscillating at a certain higher speed, and causing the steering wheel to shake, the drive axle is erected first, the front wheel is plugged with a safety plug block, the engine is started and gradually shifted into the high-speed gear, so that the driving wheel reaches the final test oscillation speed.

The speed of 120 is because the body is shaking.

1. The tire pressure is too high. Problems such as high tire pressure and serious wear and tear of automobile tires will lead to the phenomenon of body shaking when the car is driving at high speed. It is necessary to stop the car in time, check the condition of the tire, and replace it in time if there is a spare tire.

2. Poor oil quality. Poor oil quality and abnormal ignition system will cause the car to shake due to weak engine at high speeds. It is necessary to change the good quality engine oil and check the ignition system in time.

3. Power imbalance. If the half-axle clearance of the front-wheel drive vehicle is too large or deformed, and the drive shaft of the rear-wheel drive vehicle is deformed, it will lead to power imbalance and cause body shaking. You need to go to the 4S shop for maintenance in time.

4. The brake disc is worn. If the surface of the brake disc is uneven, the braking force will be large and sometimes small, resulting in the body shaking. The brake disc should be replaced or treated in a timely manner.

5. Throttle carbon deposits. Excessive carbon deposits on the throttle or fuel injector and chassis failure will also cause the body to shake at high speeds, and it is necessary to clean up the carbon deposits and inspect and repair the chassis.

6. Lead lumps are lost. The loss of lead on the wheel can also cause shaking, and the wheel needs to be dynamically balanced.

7. The four-wheel alignment data is wrong. The vehicle's four-wheel alignment data is confused, and the vehicle needs to be aligned with the four wheels.

8. The machine foot pad is aging. The vehicle's foot pads are aging, with poor elasticity and shock absorption performance, and need to be replaced in time.

9. The ball joint is worn. The ball head in the cage is seriously worn and needs to be replaced at the 4S store in time.

10. The shock absorber is damaged. The shock absorbers are not performing well and do not absorb vibrations well, so the shock absorbers on the car need to be checked and repaired or replaced.

There is a problem with the dynamic balance of the wheels, and the general problem of dynamic balancing is solved.

1. This has something to do with the design of the center of gravity of the car. We all know that some sports cars have a low center of gravity, so they are designed to reach speeds of more than 300 kilometers per hour, and on the other hand, a sedan is generally more stable at high speeds than SUVs of the same platform. Therefore, the lower the vehicle's center of gravity, the better the stability at high speeds and the better the handling.

2. It is related to the aerodynamic design of the car. This is what we usually call the drag coefficient, the lower the drag coefficient, the better the stability at high speeds. Generally speaking, according to a good design, the speed of the air flow under the car should be greater than the speed of the air flow above the body, and this difference in air pressure will cause the air to press the car firmly on the ground (the so-called air downforce), and the faster the speed, the more obvious the effect.

3. It is related to the suspension design of the car. The suspension of the car is hard and soft, the spring travel of the hard suspension is short, the body is stable, but the shock absorption is not ideal, and the body bumps are more serious. The soft suspension spring travel is long, the body stability is poor, the body shaking response is more sensitive, the high-speed stability is poor, and the soft suspension will have a more intense response when it encounters a cross wind or strong air flow.

Hello high-speed driving body shaking, mainly two aspects:

1.The dynamic balance of rotating parts such as tires and half-shafts is not good, and centrifugal force causes the vehicle to shake;

2.The transmission efficiency of the engine and gearbox is low, and the lack of power causes the vehicle to shake during driving.

If the body shakes only at about 120 yards, it may be caused by body resonance. Other situations are possible. Resonance is the most likely.

Whether the chassis is bumped, go to the next four-wheel alignment, and you will know it after you finish it, and adjust it.

When the brake disc is worn inconsistently, the steering wheel will shake when the brakes are applied at high speeds. When the car brakes when it reaches a certain speed, the left and right wheels of the coaxial wheel are out of sync in a circle once or more due to the imbalance of braking torque, resulting in the image of a loose brake and a tight brake. When the braking torque imbalance reaches a certain level, the left and right wheels will roll at unequal speed, resulting in the wheels swinging back and forth, and the swing will be fed back to the steering wheel.

2. Transmission system failure: The reason for the shaking of the steering wheel of high-speed braking may also be the abnormality of the automobile transmission system, at this time, it is best to check whether the steering tie rod and the ball joint of the steering tie rod are rusty and loose.

Summary. Hello!

There are many reasons why a vehicle can shake at high speeds, and the common causes include tire imbalance, brake system failure, suspension system problems, steering system problems, and many more. Here are some possible solutions:1

Check your tires: Tire imbalance is one of the main causes of vehicle shake. You can go to an auto repair shop to adjust the tire balance or change the tire.

2.Check the braking system: A malfunction of the braking system can also cause the vehicle to shake.

You can check whether the brake discs and brake pads are badly worn, and if you need to replace them, you can go to a car repair shop to replace them. 3.Check the suspension system:

Suspension system issues can also cause vehicle shake. You can check whether the shock absorbers, springs and other parts in the suspension system are damaged or loose, and if you need to replace or adjust, you can go to a car repair shop to deal with it. 4.

Hello, what is the model of your car.

After 120 yards it doesn't shake.

Kia K5 went to the repair shop to check the suspension rubber sleeve and tie rod ball joint, and saw that Liang Jiansong was not loose or aging. Then make a four-wheel dynamic balance. This may be caused by the lead on the tire, the oak or the steel rim of the tire.

It's good to fix it, I've had this kind of problem too.
