AI Technical Summary

Technical Problem

In traditional aircraft tire structures, the positioning range of the connection between the wear-resistant rubber and the rim is small and prone to misalignment, which leads to changes in the position of the stress point, resulting in insufficient durability of the rim and easy damage.

Method used

A dual-gradient wear-resistant rubber composite structure is adopted. By setting a composite rubber between the wear-resistant rubber and the tire sidewall, a dual-gradient wear-resistant rubber composite structure is formed. The two ends of the composite rubber are designed with arc-shaped narrow structures to increase the contact area and improve the tightness of the bond.

Benefits of technology

It significantly improves the durability and service life of aircraft tires, reduces the stretching and skewing phenomenon during the application and bonding of abrasion-resistant rubber, ensures the stability of the stress point, and extends the service life of aircraft tires.
