Fig. 2 is an enlarged schematic view of a point a in fig. 1.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings: as shown in the figure, two segmentation drive shafts of flange joint, including jackshaft 1, jackshaft one end is equipped with portable universal joint 2, and the other end is equipped with fixed universal joint 3, portable universal joint is including dismantling first casing 21 and the second casing 22 of connection, be equipped with on the first casing and be used for the semi-axis 211 of being connected with differential mechanism, be equipped with spline 212 on the semi-axis, be equipped with the raceway in the second casing, raceway sliding fit has spin 41. The rolling ball, the retainer, the star-shaped sleeve and the like arranged in the second shell are in the prior art and are not repeated, and the product has the characteristic of convenient disassembly and repair if the whole vehicle is repaired or the product is overhauled after being loaded, so that the overall quality of the constant velocity universal joint driving shaft assembly is improved, and the maneuverability of convenient repair is improved

In this embodiment, as shown in the figure, a first flange 213 is provided on the first housing, a second flange 214 is provided on the second housing, and the first flange and the second flange are connected by a fastening member 9. Through first, two flange joint, simple structure, simple to operate.

In this embodiment, the fasteners are bolts and nuts, as shown. Through the bolt and nut connection, it is with low costs, excellent in use effect.

In this embodiment, as shown in the figure, a protruding ring 215 is disposed on the opposite surface of the second housing and the first housing, a first groove 222 is disposed on the first housing, and the protruding ring is inserted into the first groove and is in clamping fit with the inner wall of the first groove. Has the positioning effect and can not shake.

In this embodiment, as shown, a dust cover 5 is further included, and the second housing is connected with an outer cover 12, one end of the dust cover is connected with the axial outer wall of the intermediate shaft through a first clamp 92, and the other end of the dust cover is connected with the second housing through a second clamp 93.
