AI Technical Summary
Existing air spring stiffness adjustment technology suffers from problems such as discontinuous stiffness changes, response delays, low control precision, and strong dependence on electronic control systems, making it unable to adapt to the high dynamic driving conditions of vehicles.
It adopts a dual-piston diaphragm air spring and an adaptive stiffness adjustment component. The stiffness is continuously and adaptively adjusted with the compression stroke through a purely mechanical structure. The air chamber is separated by a cylindrical limiting mechanism and a floating contact, and the through hole is gradually blocked or opened to achieve continuous stiffness adjustment.
It achieves continuous adaptive adjustment of air spring stiffness, solves the problems of stiffness jump and response delay, reduces system complexity and cost, and improves vehicle ride comfort and handling stability.
