Abstract

A constant velocity fixed ball joint in the form of a counter-track joint comprising an outer joint part with outer tracks, an inner joint part with inner tracks, torque-transmitting balls accommodated in pairs of tracks, and a ball cage with cage windows in which the balls are held in a common plane. First outer tracks and first inner tracks form first pairs of tracks which diverge from one another running in a first axial direction towards the connection end of the inner joint part and hold first balls. Second outer tracks and second inner tracks form second pairs of tracks which diverge from one another running in a second axial direction towards the connection end of the outer joint part and hold second balls. First pairs of tracks are positioned radially opposite other first pairs of tracks, and second pairs of tracks are positioned radially opposite other second pairs of tracks.
