Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example one

Referring to fig. 1 ~ 6, in an embodiment of the present invention, a steering shaft dust cap assembly includes:

the two surfaces of the sealing cover 2 are provided with outer edges protruding outwards, and the middle of the outer edges is provided with a mounting hole;

The outer bushing 3 is fixed in the inner side mounting hole of the sealing cover 2 in an interference fit mounting mode, so that the sealing performance between the outer bushing 3 and the sealing cover 2 is guaranteed, a thin-wall layer for inserting and placing the steering shaft 5 is arranged at the port of the outer bushing 3, and the steering shaft 5 is connected with the thin-wall layer of the outer bushing 3 in an interference fit mode;

And the inner bushing 4 is pressed on the inner side of the outer bushing 3 and is connected with the steering shaft 5 in an interference fit mode.
