Double-guidance shift fork transmission box

摘要

A double-guidance shift fork transmission box, including a shift fork box body, wherein a shift fork transmission structure and two parallel guide shafts are mounted on the body; a transmission sliding block component is arranged between the guide shafts and can freely slide along them, and the component is connected to the transmission structure. For a conventional shift fork transmission structure having no or one guide shaft, the transmission sliding block component, in the motion process, is affected by thrust of the power output shaft and motion resistance of the shift fork transmission structure only, so that mechanical transmission efficacy and mechanical efficiency of the shift fork and the shift fork box are improved, and stress of the transmission sliding block component on non-axial direction of the guide shaft is eliminated; and thrust generated from the power output shaft is transmitted onto the shift fork transmission structure without loss.

1. A Double-guidance shift fork transmission box, comprising:
a shift fork box body mounted with a shift fork transmission structure thereon; two parallel guide shafts mounted on the shift fork box body; and a transmission sliding block component freely slidable along the guide shafts mounted between the two guide shafts and connected to the shift fork transmission structure, wherein the transmission sliding block component comprises a transmission sliding block body, a plurality of assembly blocks are mounted on two sides of the transmission sliding block body, faces of the assembly blocks in contact with the transmission sliding block body are sunken inwards to form a plurality of cylindrical grooves, a plurality of strip-shaped through holes are formed at bottoms of the cylindrical grooves, and two sides of the assembly blocks are communicated through the strip-shaped through holes.
