Transmission spindle shifting fork structure

Abstract

A transmission spindle shifting fork structure is mainly and integrally formed by a shifting fork shaft provided with an axial through hole, and a sheet-like shifting fork body. The front portion of the shifting fork body is provided with a semi-circular shifting groove, a groove opening of the semi-circular shifting groove faces towards one side, and shifting fork planes are machined on the surfaces of the two outer ends of the groove opening and each coated with an anti-abrasion coating layer. The lower end of the shifting fork body is connected to the middle section of the shifting fork shaft and contains the outer wall of the shifting fork shaft through circular-arc-shaped edges on the two sides. The two side edges of the shifting fork body are connected with the two edges of the shifting fork shaft through thickened bevel fillets correspondingly. A positioning column which inclines towards one side is arranged on the lower side wall face of the shifting fork shaft. The transmission spindle shifting fork structure has the characteristics of being reasonable in structure, convenient to use and operate, smooth in gear shifting, low in abrasion, long in service life and the like.

Description

technical field [0001] The invention relates to a transmission fork structure of a transmission main shaft, which belongs to vehicle accessories. Background technique [0002] The existing drive spindle shift fork structure is made of cast steel. When the shift fork moves the shift groove in the shift fork through the shift rod, the force-bearing fork surface in contact with it is prone to greater wear and tear due to the force of the shift fork. Different wear surfaces are produced due to uneven force, so there are defects such as unreasonable structure and inflexible and smooth movement. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art, and provide a drive spindle shift fork structure with reasonable structure, convenient use and operation, flexible and smooth shift fork, less wear and long service life. [0004] The object of the present invention is achieved through the following technical solutio...
