Abstract
A constant velocity fixed joint having an outer joint part () with outer ball tracks (), an inner joint part () with inner ball tracks (), the outer ball tracks and the inner ball tracks forming pairs of tracks (), the pairs of tracks each accommodate a torque transmitting ball (). Each two adjoining pairs of tracks comprise outer ball tracks with center lines in planes extending substantially parallel relative to one another, as well as inner ball tracks with center lines in planes extending substantially parallel relative to one another. An annular ball cage () is positioned between the outer joint part () and the inner joint part (). In an aligned joint, centers of the balls are held by the ball cage in the joint center plane and when the joint is articulated, they are guided onto the angle-bisecting plane between the longitudinal axes. The track cross-sections of the outer ball tracks and of the inner ball tracks of each pair of tracks are symmetrical relative to the axes of symmetry which, together with the planes, form identically sized angles opening in opposite directions, and each comprise a common point.
