Directional Constant Velocity Cage Universal Joint

Abstract

The invention provides a novel directional constant velocity ball cage universal joint. A steel ball is fixed on the central line of the input end, and a space track is customized according to a periodic time to be used as the output end. The time and space switching principle is applied, a directional track is overlapped on the steel ball, and therefore a speed equal to the input speed is obtained. The geometric principle of the novel directional constant velocity ball cage universal joint is that a three-dimensional ball is stable and can not move in a three-dimensional mode, three-dimensional movement is generated in a four-dimensional space, the fourth dimension is time, and walking space of the steel ball is made according to the periodic time. The overall path of the novel directional ball cage constant velocity universal joint is a Mobius ring, and the novel directional constant velocity ball cage universal joint turns four times and goes in the reverse direction two times in the process to transfer the turning included angle to a spherical surface. A directional ball cage operates in a three-dimensional mode, and the feature, changing obviously, of the ball cage is that the size and the weight of the ball cage can be lowered by 40%. The output mode of the directional constant velocity ball cage universal joint is that the front face and the back face act in a coupling mode, the contact effect and the bearing capacity both are increased in a multiplied mode, the directional constant velocity ball cage universal joint has three complete degrees of freedom, and no matter how the turning included angle changes, the directional constant velocity ball cage universal joint can keep constant. A star gear works in a suspended mode, and self consumption can be basically eliminated.

Description

technical field [0001] The invention relates to a universal mechanical transmission component, a spherical cage type constant velocity universal joint, which is used to connect various power and loads between two shafts that are not on one axis, and is mainly used in passenger cars With each dynamic change of direction transmission. technical background [0002] Birfield constant velocity spherical cage universal joint, according to its theory, when the angle α between the driving shaft and the driven shaft changes, the center of the force-transmitting steel ball is always located on the bisector of the angle between the two axes, and the distance to the two axes is equal. △COA≌△COB, so as to ensure that the main and driven shafts rotate at the same angular velocity. [0003] According to the result obtained from only one plane, the kinematic pair of the constant velocity spherical cage universal joint consists of four components. The steel ball is the force transmission m...

You can't see its trace in the movement of the two-dimensional plane, but in the three-dimensional model, it rotates synchronously with axis 1 and axis 2, and Y axis 3 rotates around Y axis 1 between zero and 180 degrees. Then make a turn around the Y axis 2 between 180 and 360 degrees, at least not considered beneficial
