Light and practical transmission shifting fork

Abstract

The invention belongs to the field of mechanical parts and particularly relates to a transmission shifting fork. The transmission shifting fork comprises a fork surface, a connecting rod, connecting rod reinforcing ribs and a shifting fork sleeve, wherein the fork surface is connected with the connecting rod in parallel, the connecting rod reinforcing ribs are arranged at the joints between the fork surface and the connecting rod and located on the two sides of the connecting rod, the connecting rod is of a Z-like folding arc shape, the height of the Z-like folding arcs on the same side of the connecting rod ranges from 20 mm to 22 mm, the front face and the rear face of the connecting rod are both provided with grooves, the connecting rod is connected with the shifting fork sleeve in parallel, and the bottom faces of the joints between the connecting rod and the shifting fork sleeve are located on the same plane. A transmission provided with the transmission shifting fork can be compact in structure and low in relative weight, and the transmission shifting fork is simple in structure, low in cost, easy to produce in a large-scale and batch mode and long in service life.

Description

technical field [0001] The invention belongs to the field of mechanical parts, in particular to a portable and practical transmission shift fork.
