AI Technical Summary

Technical Problem

Existing air spring chambers, while ensuring structural strength, are too heavy and bulky, making it difficult to balance lightweight and compactness. They are also highly complex to manufacture and have a low yield rate.

Method used

The main body of the air chamber is made of plastic and surrounded by fiber reinforcement. The high mechanical strength of the fiber material is used to reinforce the main body of the air chamber, avoiding the use of a large number of reinforcing ribs.

Benefits of technology

It effectively reduces the weight of the air chamber, improves mechanical strength and yield, simplifies the manufacturing process, meets the needs of lightweighting and energy saving, and is suitable for installation in confined spaces.
