In order to quickly attenuate the vibration of the frame and the cab, and improve the smoothness and comfort of the car's driving, the car suspension system is generally equipped with shock absorbers or airbag shock absorption. At present, the double-acting cylinder shock absorber is widely used in cars.

[0003] At present, the airbags used in the existing airbag shock absorbers often deform during long-term use, and there is no corresponding protective structure between the airbags, which causes the airbags on the airbag shock absorbers to rub against the surrounding components due to excessive deformation, thereby inevitably causing the surface of the airbags to wear. In the long run, the service life of the airbags is reduced due to wear. Therefore, it is necessary to design and modify the airbag shock absorber to solve the problem of wear caused by deformation of the airbags. Utility Model Content
