Steering gear bushing assembly with high rigidity

The invention relates to a steering gear bushing assembly, and belongs to the technical field of automobile steering. The steering gear bushing assembly comprises a bushing and a special-shaped sealing ring, a special-shaped sealing ring is sleeved on the outer surface of the bushing; a plurality of upper expansion joints are uniformly formed in the circumferential surface of the special-shaped sealing ring; the upper end of the upper expansion joint is open; lower expansion joints are arranged on the rectangular sealing ring between the adjacent upper expansion joints; and the lower end of the lower expansion joint is open. The steering gear bushing assembly is compact in structure and ingenious in design, and the structural design that the special-shaped sealing ring is arranged on the outer side of the bushing in a sleeving mode is adopted; by adopting the design, the special-shaped sealing ring is in surface contact with the contact surface of the main hole of the shell, so that the problem of abnormal so
