After everyone has their first car, their care and maintenance are very important. But people generally pay attention to the place is more important parts, and some small parts are often ignored, the car shock absorber is often ignored small parts, it is a part of the car suspension system, its main function is to suppress the spring shock caused by the absorption of elastic vibration. When people are driving on the road, the impact rebound from the road makes people feel uncomfortable, and the shock absorber can just solve this problem, on the other hand, it can also avoid damage to the car, but the shock absorber also has a service life, and it needs to be replaced with a new shock absorber when it is used for a long time.

The main purpose of automobile shock absorber is to absorb the dynamic force produced by the vehicle in the process of vibration and the elastic force produced by the vehicle floating up and down. The elasticity is mainly caused by the spring on the car tire. After the spring absorbs the elasticity, it will also produce a certain rebound. The function of the shock absorber is to absorb the elasticity here, and the purpose is to reduce the vibration caused by the spring. In terms of the quality of the shock absorber, if the shock absorber is too soft, it will not absorb vibration. If it is too hard, it will cause certain damage to the vehicle and will not play a good role in absorbing elasticity. At the same time, in the process of driving, the comfort is very poor. Generally, our family cars tend to use soft shock absorbers. First, the weight is not very heavy, Second, it also prevents the ability to buffer.

If the shock absorber of a car loses its function, the car will bounce up and down in the process of driving on the road, or you can hear the sound of heavy metal impact of the car. The car is very uneven in the process of driving, which gives people a very bumpy feeling, and also causes great wear between parts, So the normal work of shock absorber is very important, but the car shock absorber is also a consumable, if the time used for a long time, then its function will be lost, there will be some damage. So how to judge whether the car's shock absorber is faulty? Just remember these four points!

The first point is to listen to the sound. When the car is driving on a bumpy road, if you hear a heavy impact sound or a bang sound from the car, the more bumpy the road is, the more obvious the sound will be. Moreover, the sound comes from the tire, which means that the shock absorber may have a fault or may not work properly, At this time, people need to check the shock absorber in time to avoid trouble caused by the shock absorber damage!

The second point is to observe whether there is oil leakage. If the surface of the shock absorber is dry and clean, it is normal at this time. If we find that there is oil leakage above the shock absorber, it means that the hydraulic oil inside the shock absorber may leak out from the piston rod. When there is oil leakage, it means that the shock absorber can not work normally, It's time for maintenance.

The third point is to observe the elasticity of the car body. When the car is parked on the side of the road, we can press the body on the car's tires in one direction, press the car down, and release it quickly. If the car can float up and down, and the elasticity rebounds, then the shock absorber is normal. If the car just floats up and down, it's repeated several times, That means the shock absorber has failed.

The fourth point is to test the temperature. After driving for a certain distance, we park the car on the side of the road and touch the shock absorber with our hands. If the shock absorber is in a state of temperature, it means that it is in normal operation. If the shell of the shock absorber is cold, it means that it has lost its function and has been damaged.

Through the above four points, we can judge whether the shock absorber is damaged from the general direction. When we find that the shock absorber fails, we should also check whether there is oil leakage or traces of oil seepage. Because the upper part of the shock absorber is composed of oil seal gasket, gasket and sealing gasket. If there are traces of oil leakage on the shock absorber that can not be eliminated, it is necessary to pull out the shock absorber to check whether the oil seal ring or sealing gasket is broken. If there is a fracture in these two places, the shock absorber will not play a very important role in the process of operation. For a long time, the damage will be more serious.

According to the above four points, there is a general judgment on whether the shock absorber is damaged. If the oil in the shock absorber is insufficient, or there is oil leakage, the shock absorber will not play a corresponding cushioning role in the process of driving. Therefore, every once in a while, we have to carry out a comprehensive inspection on our own cars, in case of details that are not noticed in other places, and also for our personal safety. We must pay attention to safety when driving, and at the same time, we must check whether there are potential safety hazards when driving.
