AI Technical Summary

Technical Problem

Existing steering drive axles have limited steering drive force in heavy-duty vehicles, and are mostly insufficient to bear the force of a single tire on one side.

Method used

A novel large-tonnage single-sided dual-tire steering drive axle was designed, including a drive wheel assembly, a driven wheel assembly, a drive assembly, and a steering assembly. By setting C-shaped connecting bridges and steering knuckle arms on both sides of the axle housing, the connection strength of the tires and the steering transmission effect are increased, and a single-sided dual-tire structure is adopted to improve the load-bearing capacity.

Benefits of technology

It improves steering drive force and load-bearing capacity, making it suitable for heavy-duty vehicles, and enhances the load-bearing strength and shock resistance of the drive axle.
