Problems solved by technology

[0004] In the above-mentioned related technologies, the inventor believes that: when the universal joint is subjected to a large pressure in the axial direction, the pressure on the shaft acts on the star wheel, and the star wheel acts on the steel ball, so that the universal joint is located in the ball cage shell. One end of the body is in a suspended state, which can easily cause the axial pressure of the universal joint to be relatively large, thus causing the universal joint shaft to be easily damaged

Embodiment 1

[0038] refer to figure 1 , the universal joint includes a ball seat 1 and a driving shaft 21, one end of the driving shaft 21 is integrally formed with a ball head 2, the ball head 2 is swingably installed in the ball seat 1, and the end of the driving shaft 21 away from the ball head 2 is detachably connected There is driven shaft 3.

[0039] refer to figure 1 In the following, the swingable installation relationship between the ball head 2 and the ball seat 1 is described as follows. Specifically, the ball seat 1 is provided with a rotating chamber 11 for the ball head 2 to swing, and the rotating chamber 11 is hemispherical. The ball seat 1 is rotatably installed with balls 121 located around the ball head 2, and the balls 121 are evenly distributed along the circumferential direction of the ball head 2, so that the balls 121 wrap the ball head 2, so that the ball head 2 and the balls 121 are in sliding contact Then swing in the rotating chamber 11.

Embodiment 2

[0049] A ball cage type universal joint, the difference from Embodiment 1 is:

[0050] refer to figure 2 , the end of the spring 25 away from the bolt 32 abuts against the abutment cylinder 27 , and the abutment cylinder 27 slides in the slide groove 22 . The abutting member includes an abutting ball 26 sliding in the sliding groove 22 , the abutting ball 26 is located at an end of the abutting cylinder 27 away from the bolt 32 , and the abutting ball 26 also rotates in the sliding groove 22 . The side of the contact ball 26 away from the contact cylinder 27 rolls against the arc inner wall 111 , and the contact cylinder 27 defines a contact port 271 for the contact ball 26 to insert and rotate. The rolling abutment of the abutment ball 26 enables the abutment ball 26 to buffer the ball head 2 from the axial pressure, and at the same time, the rolling of the abutment ball 26 makes the abutment ball 26 contact with the inner wall of the arc after being subjected to axial pres...

Abstract

The invention relates to a ball cage type universal joint, and relates to the technical field of universal joints. The ball cage type universal joint comprises a ball seat, a plurality of balls rotatably arranged in the ball seat, and a ball head which is arranged in the ball seat and slidably abuts against the balls, a rotating cavity for the ball head to swing is formed in the ball seat, a sliding groove is formed in the ball head, and an abutting piece is movably arranged in the sliding groove; and an elastic piece which enables the abutting piece to abut out of the ball head is further arranged in the sliding groove, and an arc inner wall which abuts against the abutting piece is arranged on the cavity wall, facing the ball head, of the rotating cavity. The elastic piece and the abutting piece are arranged, the elastic piece acts on the abutting piece, so that the abutting piece abuts against the arc inner wall in a sliding manner, axial pressure borne by the ball head is buffered, the ball head is supported, resistance abrasion is reduced, the service life is prolonged, and noise is reduced; and therefore, the universal joint has the advantage that damage caused by larger axial pressure on the universal joint is reduced.

Description

technical field [0001] The present application relates to the technical field of universal joints, in particular to a ball cage type universal joint. Background technique [0002] At present, universal joints are universal joints, which are parts that realize variable-angle power transmission. They are used to change the position of the transmission axis. It is the "joint" part of the universal transmission device of the automobile drive system. The combination of universal joint and transmission shaft is called universal joint transmission. On vehicles with front-engine rear-wheel drive, the universal joint transmission device is installed between the output shaft of the transmission and the input shaft of the drive axle final drive; while the vehicle with front-engine front-wheel drive omits the drive shaft, the universal joint is installed Between the axle shaft of the front axle, which is responsible for both driving and steering, and the wheels.
