[0002] Automobile chassis shock absorber, commonly known as shock absorber or shock absorber, is one of the important components of automobile suspension system. Its function is to reduce the vibration and bumps generated when the vehicle is driving, improve the stability, comfort and handling of the vehicle, and its main function is to store and release the energy generated by the uneven road surface, thereby playing the role of buffering and supporting the vehicle body. Shock-absorbing springs usually work with shock absorbers to provide better driving stability and ride comfort. When the car is more violently bumpy during driving and the weight in the car is large, the spring inside the shock absorber will shrink faster. If the spring shrinks too fast, the vehicle body may vibrate more violently, and passengers will feel more bumps, affecting the ride comfort. Utility Model Content

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0017] The present application provides a car chassis suspension shock absorber, which is mainly used to solve the problem that when a car is violently bumped during driving and the weight inside the car is large, the spring inside the shock absorber will shrink faster, and the spring shrinking speed is too fast, which may cause the car body to vibrate more violently, and the passengers will feel more bumps, affecting the riding comfort. The following technical solutions are provided. Figure 1-Figure 3 Make a detailed description:
