ABSTRACT:
A constant velocity ball joint in the form of a counter track joint, has an outer joint part, an inner joint part, and torque transmitting balls received in pairs of tracks formed of outer tracks and inner tracks, and a ball cage. First pairs of tracks whose first control angles open in a first axial direction hold first balls. Second pairs of track whose control angles open in a second axial direction hold second balls. The control angles are defined as angles between the tangents at the ball contact points in the pairs of tracks. The outer joint part and the inner joint part are axially displaceable relative to one another. The first control angle and the second control angle change in opposite senses when a relative axial displacement occurs. The axial displacement path is limited to observing a minimum value of least 8° for the respective smaller control angle.
