Embodiment Construction

[0010] Such as figure 1 As shown, it is an embodiment of an improved structure of a universal joint of the present invention, which includes a bell-shaped shell 1 of the outer cover of the tripod pin assembly. The shells are provided with an elastic clamping structure that cooperates with each other so that the back cover and the bell-shaped shell are elastically clamped together. The elastic clamping structure includes a hook 5 at the front end of the back cover, and a slot 3 is provided on the rear end surface of the bell-shaped housing, and a flange 4 at the front end of the clamping hook is provided in the slot. The inner side of the card slot 3 is provided with chamfers, and the rear end of the hook 5 is provided with a bent structure 6, and the bent structure is attached to the inner side chamfered surface of the card slot and the end surface of the bell-shaped shell.

Abstract

The invention discloses a universal joint improved structure. The structure comprises a bell-shaped shell of a three-pin assembly outer cover, wherein the rear end of the bell-shaped shell is provided with a rear cover; and elastic clamp structures matched with each other are arranged between the rear cover and the bell-shaped shell to ensure that the rear cover and the bell-shaped shell are elastically clamped together. The universal joint ensures that the rear cover and the bell-shaped shell are elastically clamped together. Compared with screw connection, the universal joint improved structure does not require drilling a thread hole, and has simple structure and convenient assembly.

Description

technical field [0001] The invention relates to an improved structure of a universal joint. Background technique [0002] In the prior art, there is a constant velocity universal joint drive shaft assembly structure. The left end of the intermediate shaft is a universal joint composed of a star sleeve, a steel ball cage, a bell shell, and steel balls. The bell shell is connected with a transmission shaft connect. The right end of the intermediate shaft is a three-pin assembly structure, and the outside of the three-pin assembly is covered with a bell-shaped shell. However, this fixing method between the back cover and the bell-shaped case not only needs to drill threaded holes, but also is cumbersome to install screws. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improved universal joint structure, the back cover of which has a simple structure and is easy to install. [0004] In order to solve the above...
