AI Technical Summary

Technical Problem

In the existing technology, the connection structure between the air spring piston and the shock absorber has insufficient anti-rotation torque in both the circumferential and axial directions, resulting in relative rotation, generating noise and reducing sealing performance. Furthermore, it requires destructive disassembly during repairs, increasing maintenance costs.

Method used

The first and second connecting parts are fixedly connected by bolts or welding, combined with elastic seals, to ensure the air spring piston and the shock absorber are fixed in the circumferential and axial directions. The prestress direction of the elastic seal is parallel to the pressure direction of the connecting parts to ensure sealing.

Benefits of technology

This achieves a reliable connection between the air spring piston and the shock absorber, reducing assembly difficulty and maintenance costs, while improving sealing and connection stability and avoiding destructive disassembly.
