If the shock absorber of the car is broken, will it flutter when running at high speed?

Under normal circumstances, it will not flutter, but the driving comfort will be reduced. Shock absorbers for automobiles.

The main function is to support the body and filter the vibration caused by the uneven ground.

Here's how to tell if there's a problem with the shock absorber:

First of all, make the car stop after driving 10km on the road surface with poor road conditions, touch the shock absorber shell with your hands, if it is not hot enough, it means that there is no resistance inside the shock absorber, and the shock absorber does not work. At this time, an appropriate lubricating oil can be added, and then the test can be carried out if the housing is hot.

It is a lack of oil inside the shock absorber, and sufficient oil should be added; Otherwise, the shock absorber is out of order.

Press down firmly on the bumper.

Then let go, and if the car has 2 or 3 jumps, the shock absorbers are working well. Emergency braking when the car is driving slowly.

If the vibration of the car is more violent, it means that there is a problem with the shock absorber. You can also remove the shock absorber to stand upright, and clamp the lower end connecting ring on the vice, pull and press the damping rod several times, there should be stable resistance at this time, and the resistance to pull up should be greater than the resistance when pressing down, if the resistance is unstable or there is no resistance, it may be that the shock absorber is lacking oil inside or the valve parts are damaged, and the parts should be repaired or replaced.

Hello, of course it will, the car is driving on the road and the tires fluctuate all the time, if the shock absorber is broken, it can not play a cushioning role, which will make the vehicle unstable. Hope it can help you [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, it won't be unhappy when crossing a bumpy road [If there is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello! I'm glad to have your question, the car shock absorber is broken, there will be a feeling of fluttering when running at high speed, because the car shock absorber is broken, there will be no more shock absorption function, the spring is left in the struggle, the spring encounters bumps, it will flicker up and down, and the car shock absorber is broken, when the road is uneven, the car will be very noisy, and the vibration will be very large, which is caused by the shock absorber can not play the role of shock absorption, at this time it is best to check it, to replace it in time, So as not to hurt the car, I hope mine can help you, I hope you can.

Generally, after the shock absorber is damaged, there are the following fault manifestations:

1. Oil leakage from shock absorber. The outer surface of the normal shock absorber is dry and clean, if there is oil seeping out, it means that the hydraulic oil inside the shock absorber escapes from the upper part of the piston rod, and the shock absorber has basically failed in this case;

2. When the car crosses the bumpy road or speed bump, a certain wheel makes a "clang" sound, indicating that the shock absorber on the wheel has a poor damping effect or fails;

3. When the car is cornering, it obviously feels that the body roll increases, and even the side slip will occur in serious cases, which is mainly because the damping force of the shock absorber is too small and cannot effectively suppress the compression of the spring;

4. After the car is driving in rough road conditions for a period of time, touch the shock absorber shell with your hand to feel the temperature of the shock absorber, under normal circumstances, the shock absorber shell is warm, if a shock absorber shell is cold, it means that the shock absorber has been damaged;

5. When the car is stopped, when the corner of the car body is pressed down and released, the body will be stable under the spring force, and if it tends to stabilize soon after the car, the shock absorber is good; If it stops after repeating ** several times, it means that the damping effect of the shock absorber is a little poor.

The shock absorber, as the name suggests, is to reduce the vibration, if it is broken, the impact is that the vibration cannot be reduced, the car does not stop moving, and it runs bumpy, just like riding a tractor.

The shock absorber is a vulnerable part in the process of car use, the shock absorber works well or badly, which will directly affect the stability of the car and the life of other parts, so we should always make the shock absorber in good working condition. The following methods can be used to verify whether the shock absorber is working well.

1. Make the car stop after driving 10 kilometers on the road surface with poor road conditions, touch the shock absorber shell with your hands, if it is not hot enough, it means that there is no resistance inside the shock absorber, and the shock absorber does not work. At this time, you can add appropriate lubricating oil, and then carry out the test, if the shell is hot, it is a lack of oil inside the shock absorber, and sufficient oil should be added; Otherwise, the shock absorber is out of order.

2 Press the bumper firmly and then release, if the car has 2 3 jumps, then the shock absorber is working well.

3 When the car is driving slowly and braking urgently, if the car vibrates violently, it means that there is a problem with the shock absorber.

4 Remove the shock absorber and put it upright, clamp the lower end connecting ring on the vice, and pull the shock absorber bar several times. The resistance of recovery should be greater than the resistance when pressing down, if the resistance is unstable or there is no resistance, it may be that there is a lack of oil inside the shock absorber or the valve parts are damaged, and the parts should be repaired or replaced.

After determining that the shock absorber is faulty or failing, you should first check the shock absorber for oil leakage or signs of old oil leakage.

If oil leakage is found, first tighten the cylinder head nut, if the shock absorber is still leaking, it may be that the oil seal and sealing gasket are damaged and failed, and the new seal should be replaced. If the oil leakage still cannot be eliminated, the shock absorber rod should be pulled out, if you feel a hairpin or a difference in weight, further check whether the gap between the piston and the cylinder barrel is too large, whether the piston connecting rod of the shock absorber is bent, and whether the piston connecting rod surface and cylinder barrel are scratched or stretched.

If there is no oil leakage in the shock absorber, the shock absorber connecting pins, connecting rods, connecting holes, rubber bushings, etc. should be checked for damage, desoldering, cracking or falling off. If the above inspection is normal, the shock absorber should be further decomposed, check whether the matching gap between the piston and the cylinder barrel is too large, whether the cylinder barrel is strained, whether the valve seal is good, whether the valve disc and the valve seat are tightly fitted, and whether the extension spring of the shock absorber is too soft or broken, and repair or replace the parts according to the situation.

In addition, the shock absorber will make a sound in the actual use of the fault, which is mainly due to the shock absorber and the leaf spring, frame or shaft collision, rubber pad damage or falling off and shock absorber dust cylinder deformation, insufficient oil and other reasons, should be found out the cause, to be repaired.

An oil leak is considered bad.

2. The car runs on a bumpy road and makes a clattering sound.

Abnormal noise: If the shock absorber makes an abnormal noise when the vehicle is driving on a bumpy road, it is very likely that the shock absorber has been damaged.

Oil Leakage: Inspect the shock absorber through the wheel arch with a flashlight, and if there is an oil leak on the outside of the shock absorber, it indicates that the shock absorber has been damaged.

Loose chassis: When the vehicle is driving to a bumpy road, if you find that the body attitude is too bumpy and swaying, it is generally a problem with the shock absorber.

You're all right, you're all amazing.

The most important thing for us is to improve the comfort of the car, the shock absorbers, and reduce the frequency of the car going up and down. What should I do if my car's watch is broken? Note that the shock absorber is mainly cushioned by spring damping.

Once the shock absorber fails, the car will feel bumpy while driving, but this is only very simple, and the biggest impact is the stability of the body.

First, the working principle of automobile shock absorber.

To know how a car shock absorber is broken, you must first know how the shock absorber works. It is not used to support the weight of the body, but to suppress the vibration when the rear spring bounces, and absorb the impact of the road surface like a spine. It's not that the springs are useless, but there is no damping, the springs can't be slowly rebounded and compressed, and sitting in the car will feel uncomfortable and bumpy.

Second, the performance and solution of the broken shock absorber.

Oil leakage and abnormal noise are the most common phenomena of broken meters of automobile shock absorbers, and oil leakage accounts for the majority. When the shock absorber slag seeps is working properly, it depends on the hydraulic oil inside. Once an oil leak occurs, the performance of the shock absorber will naturally deteriorate, and if there is too much oil leakage, it may break down completely.

We can tell if the oil spill is bad by looking at the quality of it.

Generally speaking, if there is fresh oil on the shock absorber, it means that the oil leakage is serious. If there is no fresh oil, but there is some oil stain, the oil leak is not very serious. It may be that there is a little leak in some special cases, and this situation can be used for a while.

If the shock absorber is completely damaged, it can only be replaced. After all, it's just a one-time device, but most of them only need to be replaced. But if you use the car a lot, you have to go through a lot of speed bumps every day, the speed is relatively fast, and you often take some bumpy roads, and the kilometers of the car are relatively large, then you had better change the left and right together.

Because the damage of the shock absorber has a lot to do with the way the car is used, the harsh driving environment will cause the performance of the shock absorber to decay rapidly, if the shock absorbers on both sides are not the same, the hardness will vary greatly, when driving on bumpy roads, one side will be very high, and the other side will be very low, resulting in poor body stability and easy rolling, so

Millions of car purchase subsidies.

1. Yes, serious will cause safety accidents. Therefore, it is necessary to replace the shock absorption system when the shirt is finished to ensure driving safety.

2. The car obviously feels that the body roll increases when cornering, and even sliding will occur in serious cases, which is mainly because the damping force of the shock absorber is too small, and after damage, the vehicle will feel shake when stepping on the brakes, and the shaking will disappear when the brakes are released.

3. Jian or Qin should go to the 4S shop for maintenance in time to avoid greater safety accidents, and ask a professional car master to replace the new shock absorption system.

1. Yes, serious will cause safety accidents. Therefore, it is necessary to replace the shock absorption system in time to ensure driving safety.

2. When the car is cornering, it is obvious that the car clears the gear and the roll increases, and even the side slip will occur when it is serious, which is mainly because the damping force of the shock absorber is too small, and after damage, the vehicle will feel shake when stepping on the brakes, and the shaking will disappear when the brakes are released.

3. It is recommended to go to the 4S shop for maintenance in time to avoid greater safety accidents, and ask a professional car master to replace the new shock absorption system.
