Connecting assembly for dual universal half shafts of vehicle driving axle

Abstract

The invention discloses a connecting assembly for dual universal half shafts of a vehicle driving axle. The connecting assembly comprises a connecting fork, wherein the connecting fork has a hollow cylindrical structure of which the two ends are open; a pair of first opposite lugs projects from the end face of the first axial end of the connecting fork; a pair of second opposite lugs projects from the end face of the second axial end of the connecting fork; a central connecting line between two the two first lugs is vertical to a central connecting line between the two second lugs. The connecting assembly has the beneficial effects that inner and outer half shafts do not occupy the corner space of each other while rotating along the same direction, the problem of incapability of meeting the requirement on the turning angle during running of the vehicle due to a small turning angle during running of the vehicle, caused by mutual interference of the conventional inner and outer half shafts rotating along the same direction is solved, the overall length of the connecting fork can be reduced, and the overall structure of the connecting fork is more compact; an eccentric structure and a cutting structure are not required, and the connecting assembly has the advantages of low manufacturing cost, high structural strength and long service life.

Description

technical field [0001] The invention relates to a vehicle drive axle, in particular to a connection assembly of double universal joint half shafts of a vehicle drive axle. Background technique [0002] The connection assembly of the drive axle shafts of the existing various automobiles, engineering vehicles, loaders and special vehicles can meet the driving and steering angle of the vehicle during driving. The existing drive axle half shaft assembly of the vehicle, its The structure generally includes an outer half shaft, an inner half shaft and a connecting fork for connecting the outer half shaft and the inner half shaft. The connecting fork is a hollow cylinder structure with open ends. The outer half shaft and the connecting fork The first end in the axial direction is connected by a first cross shaft universal joint, a pair of opposite first fork lugs protrude from the end face of the first axial end of the connection fork, and an outer fork is provided on the correspon...

AI Technical Summary

Problems solved by technology

Although this change satisfies the turning angle of the vehicle during driving, it does not eliminate the problem that the overall structure is not compact. It is a certain degree of difficulty, which makes the manufacturing cost higher than that of the cross-axis universal joint, and the cutting of the eccentric cross-axis universal joint corresponding to the interference part directly affects the structural strength of the product, thus affecting the use of the vehicle drive axle life
