Embodiment Construction

[0016] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0017] Such as figure 1 As shown, a single-sphere constant velocity universal joint drive shaft assembly of the present invention includes a universal joint 1 and a half shaft 2. The outer surface of the housing 3 of the universal joint has an outer spherical portion 4; A dust jacket 5, the inner surface of the dust jacket 5 has an inner spherical surface 6 compatible with the outer spherical surface 4, one end of the dust jacket is fixed on the half shaft 2, and the other end is lapped on the On the outer spherical portion 4 of the housing and when the housing rotates relative to the dust cover, the opening end 11 of the housing always falls in the dust cover 5 . In the present invention, the dustproof cover is lapped on the outer spherical surface of the housing, and when the housing rotates relative to the dustproof cover, the open end of the housing always fa...

Abstract

The invention provides a single sphere drive shaft assembly for a constant velocity universal joint, and solves the problem that the dust cloth of the conventional driving shaft ages easily due to fatigue, has a shorted service life, and is complex in assembly process. The drive shaft assembly comprises a universal joint and a half shaft, and further comprises a dust cover, wherein the outer surface of the housing of the universal joint has an outer spherical surface part; the dust cover is made of Santoprene; the inner surface of the dust cover has an inner spherical surface part matched with the outer spherical surface part; one end of the dust cover is fixed on the half shaft; the other end of the dust cover is overlapped on the outer spherical surface part of the housing; and when the housing rotates relative to the dust cover, the open end of the housing is arranged in the dust cover all the time. The drive shaft assembly has the advantages that the service life of the dust cover is long and the structure is simple.

Description

technical field [0001] The invention relates to a drive shaft assembly of a single-sphere constant velocity universal joint. Background technique [0002] At present, the constant velocity universal joint drive shaft assembly assembled on the car includes a fixed end universal joint, a half shaft, a dust cover, and a sliding end universal joint assembly. Among them, the dust cover is corrugated, and one end passes through The hoop is fixed on the half shaft, and the other end is fixed on the housing of the fixed end universal joint through the hoop. The constant velocity universal joint drive shaft assembly of this structure needs to use pliers to clamp the hoop to fix the dust cover on the half shaft and the fixed end universal joint when assembling the dust cover, and the assembly process is complicated. Furthermore, the dust cover is corrugated, and when the vehicle turns, that is, the half shaft and the fixed end universal joint form a larger angle, the corrugation spac...
