[0002] The shift fork is a part of automobile parts, mainly used to push the sliding gear. There is a ring groove on the sliding gear and the shift fork rides in this ring groove. When the driver pushes the shift lever, the shift lever drives the shift fork shaft, the shift fork shaft drives the shift fork, and the shift fork pushes the gear to achieve gear shifting.

[0003] According to a disclosed shift fork device with a long service life for an automobile engine (publication number: CN207213129U), the service life of the shift fork can be effectively improved by providing a fork foot protective layer and a crescent-shaped friction plate in the above application. Chrome plating on the surface of the fork foot protective layer and the crescent-shaped friction plate further increases the wear resistance of the shift fork.
