ABSTRACT:
A constant velocity universal ball joint has an outer joint part and an inner joint part. Each part is provided with a plurality of ball tracks extending substantially in a longitudinal direction. The balls provide torque transmission and are guided in radially opposed tracks in the outer joint part and in the inner joint part. A cage with cage windows holds each ball in a plane positioned perpendicularly relative to the longitudinal axis. The cage includes a mechanism which, if the axes of the outer joint part and the inner joint part deviate from one another, guide the cage with the balls on to the angle-bisecting plane. Each of the track faces of the ball tracks, at the outer joint part and/or at the inner joint part, are subjected to loads by the balls, as well as each of the regions of the surfaces adjoining the ball tracks, which are guiding faces for the cage, undergo a hardening operation. Also, unhardened zones are provided between each two ball tracks between the guiding faces.
