AI Technical Summary

Technical Problem

Existing air spring structures suffer from high costs, long development cycles, and inconvenient disassembly and assembly in the development of vehicle platforms, especially due to structural component damage caused by traditional snap-fit ​​connection methods and the diverse requirements for mounting bracket molds.

Method used

The rotating cover and the undulating piston are connected by threads, combined with a sealing ring design, to achieve an adjustable air chamber volume for the rotating cover and the undulating piston. The mounting base and the lower swing base are connected by threads and sealing rings, replacing the traditional snap-fit ​​method.

Benefits of technology

It enables convenient disassembly and assembly of air springs and volume adjustment, reduces development costs and cycle, meets the needs of vehicle platform development, and improves sealing performance and structural durability.

Abstract

This utility model discloses a volume-adjustable air spring, including an undulating piston and a rotating cover. The undulating piston is connected to a lower pivot seat via a bladder, and is threadedly connected to the end of the rotating cover opposite to the lower pivot seat. In this utility model, the threaded connection between the rotating cover and the undulating piston facilitates the connection of rotating covers of different sizes with the undulating piston, thereby configuring the air chamber formed by the undulating piston and the rotating cover into different volumes. This achieves different stiffness requirements, saves development time and costs, and facilitates the platform-based development of air springs.
