See full text

A fixed type constant velocity universal joint has pairs of track grooves, each pair forming a wedge angle (α). The wedge angle (α) includes a wedge angle (α0) formed, when an operating angle is 0°, with respect to each of torque transmitting balls arranged in a joint center plane, and opening to the same side in an axial direction for all pairs of track grooves. Further, the pairs of track grooves are mirror-image symmetrical with each other when the operating angle is 0°.
