The joint consists of an outer joint part and an inner hub, defining tracks for a transmission ball. Some of the tracks are at an angle of inclination relative to a second plane, which is of the same size as but facing in opposite direction to, associated tracks in the joint part (2) and corresponding hub tracks. The angled tracks are distributed among all tracks in such a way, that two translatory and one rotatory degree of freedom of the hub (3) are limited relative to the joint part, and so that all balls (4) share in power transmission.
