Introduction To Inflatable Shock Absorbers

Inflatable shock absorber is a new type of shock absorber developed since the 1960s. Its structural feature is that a floating piston is installed in the lower part of the cylinder, and a closed air chamber formed by the floating piston and one end of the cylinder is filled with high-pressure nitrogen. A large-section O-ring seal is installed on the floating piston, which completely separates oil and gas. The working piston is equipped with a compression valve and an expansion valve that change the cross-sectional area of the channel according to its moving speed. When the wheel bounces up and down, the working piston of the shock absorber reciprocates in the oil, causing an oil pressure difference between the upper cavity and the lower cavity of the working piston, and the pressure oil pushes the compression valve and the expansion valve to flow back and forth. Since the valve produces a relatively large damping force on the pressure oil, the vibration is attenuated.
