AI Technical Summary

Technical Problem

Existing air spring shock absorbers cannot automatically adjust their stiffness according to changes in road conditions or load, resulting in a fixed damping effect that cannot meet the comfort and stability requirements under different working conditions.

Method used

A variable stiffness air spring shock absorber was designed. Through the through-type movable connection between the outer casing and the shock absorber body and the combination of the floating piston and the air bladder, the stiffness of the shock absorber body is adjusted by the expansion or contraction of the air bladder, so as to achieve continuous stiffness adjustment.

Benefits of technology

It improves the comfort and stability of air spring shock absorbers, meets diverse needs under different working conditions, reduces lateral offset loss, and provides reliable connection and maintenance convenience.

Abstract

This utility model belongs to the technical field of shock absorbers for two-wheeled vehicles, and particularly relates to a variable stiffness air spring shock absorber, comprising: an outer cover, a shock absorber body movably passing through one side of the outer cover, and connecting members provided on both the side of the shock absorber body away from the outer cover and the side of the outer cover away from the shock absorber body, the two connecting members being used to connect to an external support point; wherein, the piston rod of the shock absorber body is located inside the outer cover and connected to the side of the outer cover away from the shock absorber body, and the shock absorber body is slidably connected to the outer cover via a floating piston sleeved on the outside. This utility model adjusts the stiffness of the air spring by inflating or contracting the air spring and contacting it with the floating piston at different diameters, thereby improving the comfort of the air spring shock absorber, and thus achieving continuous adjustment of the shock absorber stiffness to meet diverse needs for comfort and stability under different working conditions.
