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 Construction
[0030] The following is attached figure 1 The application is described in further detail.
[0031] The embodiment of the present application discloses a ball cage type universal joint.
[0032] 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.
[0033] The swingable installation relationship between the ball head 2 and the ball seat 1 is described below. 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 w...

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 rotationally arranged in the ball seat, and a ball head arranged in the ball seat and slidably abutting 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 a sliding abutting part is slidably arranged in the sliding groove; and a spring which enables the sliding abutting part to abut out of the ball head is further arranged in the sliding groove, and the cavity wall, facing the ball head, of the rotating cavity is provided with an arc inner wall matched with the sliding abutting part. According to the universal joint, the spring and the sliding abutting part are arranged, and the spring acts on the sliding abutting part, so that the sliding abutting part abuts against the arc inner wall in a sliding mode, the axial pressure borne by the ball head is buffered, the ball head is supported, and therefore the universal joint has the beneficial effect that damage caused by large axial pressure borne by the universal joint is relieved.
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. [0003] Related techn...
