Information

Many people know the function of automobile shock absorber, but many people don't know how to check automobile shock absorber. What are the methods to check the fault of shock absorber?

The working automobile shock absorber can reduce the impact of the road on the automobile, quickly absorb the vibration brought by the bumps, and make the vehicle return to the normal driving state. What kind of reaction will the abnormal automobile shock absorber have? Press firmly on the bumper and release it. If the car jumps 2 ~ 3 times, the shock absorber works well; otherwise, it cannot work normally.

       

Remove the shock absorber and erect it, clamp the lower connecting ring on the vise, pull and press the shock absorber several times. At this time, there should be a stable resistance, the pull-up resistance should be greater than the pressure resistance. If the resistance is unstable or there is no resistance, it may be due to lack of oil in the shock absorber or damaged valve parts, so repair or replace the parts. After driving 10km on the road with poor road conditions, stop the car and touch the shock absorber shell with hands. If it is not hot enough, there is no resistance inside the shock absorber and the shock absorber does not work. At this time, appropriate lubricating oil can be added, and then the test can be carried out. If the shell is hot, the shock absorber is short of oil, add enough oil; otherwise, the shock absorber will fail.

Shock absorber will produce noise in actual use, which is mainly caused by the collision between shock absorber and leaf spring, frame or shaft, damage or falling off of rubber pad, deformation of shock absorber dust tube, lack of oil and other reasons. It is necessary to find out the reasons and repair. The normal operation of the shock absorber can ensure us to move forward more smoothly in the process of driving, so we need to check whether the shock absorber works normally in time.
