Embodiment Construction

[0010] Such as figure 1 As shown, it is an embodiment of a three-pin universal joint of the present invention, which includes a bell-shaped housing 1 that is arranged outside the three-pin assembly 7 at the right end of the intermediate shaft, and the right end of the bell-shaped housing is provided with a transmission shaft The hole 2 is provided with meshing teeth 3 in the hole of the transmission shaft, and the pin hole 4 passing through the hole of the transmission shaft is provided in the radial direction of the bell-shaped shell. The transmission shaft hole communicates with the cavity where the three-pin assembly is located, and the left end of the transmission shaft hole is provided with a blocking cover 6 to separate the transmission shaft hole and the cavity where the three-pin assembly is located. A step 5 is provided at the left end of the transmission shaft hole, the blocking cover is cylindrical, and the opening end of the blocking cover is fastened on the step.

Abstract

The invention discloses a three-pin universal joint, which comprises a bell-shaped shell arranged outside a three-pin assembly on the right end of an intermediate shaft, wherein a drive shaft hole is formed on the right end of the bell-shaped shell; an engaged tooth is arranged in the drive shaft hole; and a pin hole which runs through the drive shaft hole is formed on the bell-shaped shell in a radial direction. In the invention, the pin hole which runs through the drive shaft hole is formed on the bell-shaped shell in the radial direction, so that the position of a drive shaft can be fixed by a pin shaft and influences of the slide of the drive shaft in the drive shaft hole on normal working are prevented.

Description

technical field [0001] The invention relates to a three-pin universal joint. Background technique [0002] The three-pin universal joint is a common universal joint whose main function is to transmit the torque of the engine gearbox through the moving end to the wheels. Chinese utility model patent 200710132411.6 disclosed a three-ball joint assembly of a three-ball universal joint on February 27, 2008. The specific structure is that the intermediate shaft connects the three-ball universal joint, and the three-ball universal joint The knuckle bell housing is connected with the transmission shaft, wherein the transmission shaft is arranged in the transmission shaft hole at the rear end of the bell housing, and the transmission shaft hole is provided with meshing teeth for meshing transmission with the transmission shaft. Because the transmission angle is changed through the universal joint, the transmission shaft is very unstable in the transmission shaft hole, and it is eas...
