Constant velocity universal joint structure with locking structure

Abstract

The invention discloses a constant velocity universal joint structure with a locking structure. The constant velocity universal joint structure comprises a ball cage body, a clamp spring, a locking rod, a push rod, a telescopic spring and a locking rod. The push rod is connected with the ball cage body in a sliding manner, one end of the telescopic spring is connected with the push rod, the other end of the telescopic spring is connected with the ball cage body, and the locking rod is rotationally connected with the ball cage body. A clamping groove is formed in the side wall of one side of the locking rod, one end of the push rod is matched with the clamping groove and arranged in the clamping groove, a locking inclined face is arranged on the side wall of the push rod, a limiting ring groove is formed in the outer side wall of the ball cage body, the clamp spring is arranged in the limiting ring groove in a sleeved mode, one end of the locking rod makes contact with the locking inclined face, and the other end of the locking rod makes contact with the inner wall of the clamp spring. According to the constant velocity universal joint structure with the locking structure, the connecting structure of the ball cage body is convenient to disassemble and assemble and is slightly limited by space; and the connecting structure of the ball cage body is more reliable.

Description

technical field [0001] The invention relates to the technical field of constant velocity universal joints, in particular to a constant velocity universal joint structure with a locking structure. Background technique [0002] In the prior art, the outer spherical cage end of the drive shaft assembly of the constant velocity universal joint is connected with the vehicle wheel hub, fastened by nuts or bolts, and the inner spherical cage is connected with the gearbox, and the axial fixing and locking are realized by the circlip. tight. Since the inner ball cage end of the constant velocity universal joint drive shaft assembly is connected to the gearbox, it cannot be disassembled by direct disassembly tools due to the limited space of the chassis of the car. Therefore, disassembly and replacement have become a difficult problem. Therefore, it is necessary to design a constant velocity universal joint structure with a locking structure, which not only ensures the reliability of...
