Description

Technical Field

[0001] The utility model relates to the technical field of bushing press-fitting tooling, in particular to a press-fitting tooling for a steering knuckle bushing. Background Art

[0002] In the automotive industry, the installation of steering knuckle bushings is a crucial step in the chassis assembly process. The primary function of a steering knuckle bushing is to connect the steering knuckle to the steering tie rod, providing shock absorption, cushioning, and rotational support, directly impacting the vehicle's driving performance and comfort. Traditionally, the installation of steering knuckle bushings relies on manual press-fitting. While press-fitting can be accomplished to a certain extent, due to the instability of manual operation, traditional press-fitting equipment struggles to ensure accurate installation of the steering knuckle bushing. This can result in a poor fit between the bushing and the steering knuckle, impacting the vehicle's steering performance and durability. Furthermore, the manual press-fitting process is time-consuming and inefficient. Utility Model Content
