Abstract
The invention discloses a shifting fork with a lubrication protection function. The shifting fork comprises a shifting fork body. A shifting fork base is arranged at the upper end of the shifting fork body. Shifting fork arms are connected to the two ends of the shifting fork base, and an annular disc is connected between the shifting fork arms and is internally of a closed structure. Guiding-out openings are formed in the connecting ends of the annular disc and the shifting fork arms. Each of the upper end and the lower end of a disc body in the annular disc is provided with a lubricating agent storage cavity. Lubricating agent guiding-out openings are formed in the two sides of each lubricating agent storage cavity. A fixing supporting frame arranged in a staggered manner is arranged on the disc body on the inner side of the annular disc. Frame bodies in the middle sections of the fixing supporting frame are provided with elastic telescopic rods. By means of the above manner, the stability and lubricating performance of the shifting fork can be improved, the annular disc arranged between the shifting fork arms can strengthen the shifting fork body, and the annular disc can output a lubricating agent so that abrasion of the shifting fork can be prevented.
