Rear shock bumper application and troubleshooting

- Nov 19, 2018-

Rear shock absorbers are often used in automobiles and other products, which can improve the ride smoothness of the car, reduce the shock when the spring shocks after rebound, and the impact from the road surface. While passing through an uneven road surface, although the shock absorbing spring can filter the vibration of the road surface, the spring itself has a reciprocating motion, and the rear shock absorber is used to suppress the spring jump.


In practical applications, due to some adverse factors, the rear shock bumper may have a noise fault. The reason why this happens is mainly due to the collision of the shock absorber with the leaf spring, the frame or the shaft, the damage or falling of the rubber pad, the deformation of the shock absorber dust cylinder, the lack of oil, etc., should be ascertained. Specific reasons and timely repair.


It should be noted that after the maintenance of the rear shock bumper, the performance test should be carried out on a special test bench. When the resistance frequency is 100±1mm, the resistance of the extension stroke and the compression stroke should meet the requirements, indicating its performance. Basically normal before use.
