AI Technical Summary
In existing technologies, the wheel hub has increased overall thickness and weight due to the threaded holes at both ends of the inner ring, making it difficult to achieve a lightweight design.
The mounting part is connected to both ends of the inner ring and has threaded holes. The inner ring and the mounting part are integrally formed to increase the contact area between the rim and the inner ring. It is connected to the inner ring through the inner ring and has valve holes to facilitate tire installation.
The weight of the wheel hub has been reduced, the structural strength and reliability have been improved, and the convenience and connection stability of the wheel hub have been enhanced.
