The shock absorber is an important component in the automobile suspension system. Its function is to restrain the spring from absorbing the vibration deformation and the shock when the spring rebounds, and to absorb the impact force from the road surface. It will affect the ride comfort and maneuverability of the car, and it will also affect our driving safety. It is also a vulnerable part, with the extension of use time, performance degradation or loss of function will occur.
How to judge whether the car's shock absorber is damaged?
1. The car performs emergency braking on a safe road at a relatively slow speed, and observes whether the car's braking posture is very different from the previous feeling. If the vibration is too large, there is a problem with the shock absorber.
2. Oil leakage. The shock absorber can work normally, relying on the hydraulic oil inside. Once the oil leaks, the performance of the shock absorber will definitely decrease. If there is a lot of oil leakage, it will be completely broken, it will not work, and it must be replaced.
3. When the car is in a stopped state, when we press down and release a corner of the car body, the car body will rebound under the spring force. If it stabilizes soon after the rebound, the shock absorber is good. If it stops after repeated shaking several times, it means that the shock absorption effect of the shock absorber is a bit poor.
4. Abnormal sound. The abnormal noise of the car is usually caused by the bumpy road, because the chassis can produce noise in many places. So we have to make sure it is the abnormal noise of the shock absorber. Another reason is that when it comes to winter, the temperature is low and there are abnormal noises in the bumpy road. When the temperature rises, there will be no abnormal noise. In this case, there is no need to replace the shock absorber. This is because the temperature in winter is low, the hydraulic oil in the shock absorber is too thick, and the fluidity is poor. It will be fine after winter.
