Abstract:
1. 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 which are received in pairs of tracks consisting of outer tracks and inner tracks, and a ball cage with cage windows in which the balls are held in a common plane and are guided on to the angle-bisecting plane when the joint is articulated; first outer tracks, together with first inner tracks, forming first pairs of tracks whose control angles open in a first axial direction (R second outer tracks, together with second inner tracks, forming second pairs of tracks whose control angles open in a second axial direction (R wherein the control angles are defined as angles between the tangents at the ball contact points in the tracks when the joint is in the aligned condition; the ball cage including a spherical outer face with a greatest diameter D the outer joint part forming an introducing aperture for the ball cage with an aperture diameter D the ball cage, in engaging the outer tracks, can be threaded into the outer joint part in the second axial direction (R the outer joint part forming a first stop and guiding face for a spherical outer face of the ball cage; wherein, between the introducing aperture and the first stop and guiding face, the outer joint part comprises a displacement region for the ball cage with an internal diameter of D a securing element attached at the outer joint part in front of the introducing aperture forming a second stop and guiding face for the spherical outer face of the ball cage.
