Description

Technical Field

[0001] The utility model relates to the technical field of air bag shock absorbers, in particular to a wear-resistant and corrosion-resistant automobile air bag shock absorber. Background Art

[0002] Airbag shock absorber is a kind of inflatable shock absorber, which uses air pressure resistance to achieve anti-vibration effect. In automobiles and other means of transportation, the working principle of airbag shock absorber is to inject compressed air into the airbag and use the effect of air spring to reduce the vibration between the frame and the body. This shock absorption method can effectively improve the smoothness and comfort of vehicle driving. In addition, the airbag shock absorber also alleviates the volume change of the hydraulic chamber generated by the movement of the inner rod to avoid the generation of bubbles in the shock absorber oil, thereby ensuring the stability of the shock absorption effect.
