AI Technical Summary
Existing pneumatic tires have problems with the connection between the metal outer wheel and the tread, resulting in insufficient safety and reliability, especially at high speeds.
A brass layer is formed by plating brass on the surface of the metal outer wheel, and pores and grooves in different directions are opened on the metal outer wheel. A rubber composition with a specific composition is combined with it to achieve a strong bond between the rubber and the metal outer wheel through Cu-S chemical bonds. Vulcanization is carried out using an existing movable mold.
It improves the robust connection and reliability of pneumatic tires, making them suitable for safety performance under high-speed conditions. It also improves heat dissipation and clamping capacity through the design of air holes and grooves, and reduces production costs.
