Problems solved by technology
In order to facilitate press-fitting, the conventional design will consider the demand for press-fitting guides, and add a chamfer to the edge of the mounting hole for guidance. However, due to size restrictions and matching requirements, the chamfer should not be too large, otherwise the bushing and the mounting hole will cooperate effectively. Insufficient contact area. In this case, the direct press-fitting of the bushing has insufficient guidance, improper placement, and mismatching of material hardness, etc., resulting in improper press-fitting, flanging, and cracking.

The invention discloses an assembly method for a steering gear case and a bush. A guide sleeve is adopted during assembly; the guide sleeve is placed at the position of a corresponding assembly hole in the steering gear case; then the bush is arranged in the guide sleeve; and finally, the bush is press-assembled into the assembly hole in the steering gear case. According to the assembly method for the steering gear case and the bush, a conical guide hole is formed in the guide sleeve, so that a good guide effect can be exerted on the bush during assembly, and the bush can be press-assembled in place rapidly and conveniently; and the problems of not-in-place press-assembling, edge turning-up, cracking and the like do not occur after press-assembly, so that the assembly effect of the bush and the steering gear case is improved.
Description
technical field [0001] The invention belongs to the technical field of automobile steering, in particular, the invention relates to an assembly method of a steering gear housing and a bushing. Background technique [0002] The connection and installation method of the steering gear assembly and the frame have an important impact on the performance characteristics of the steering system. The use of bushes to fix the steering gear is a widely used connection method. The bushing is made of a metal inner cylinder and rubber Material shock-absorbing sleeve composition. [0003] When assembling, insert the bushing into the mounting hole of the steering gear housing. In order to facilitate press-fitting, the conventional design will consider the demand for press-fitting guides, and add a chamfer to the edge of the mounting hole for guidance. However, due to size restrictions and matching requirements, the chamfer should not be too large, otherwise the bushing and the mounting hole...
