Abstract:
1. A constant velocity fixed joint comprising: an outer joint part which comprises a first longitudinal axis and an attaching end and an aperture end arranged so as to be axially opposite one another, and outer ball tracks; an inner joint part which comprises a second longitudinal axis and an attachment for a shaft pointing towards the aperture end of the outer joint part, and inner ball tracks, the outer ball tracks and the inner ball tracks form pairs of tracks with one another which each accommodate a torque transmitting ball; an annular ball cage between the outer joint part and the inner joint part and comprising circumferentially distributed cage windows which each accommodate at least one of the torque transmitting balls, the centers of the balls are held by the cage in a joint center plane and, upon articulation of the joint, are guided onto an angle-bisecting plane between the first and second longitudinal axes, wherein center lines of the outer and inner ball tracks, of pairs of tracks are positioned in pairs of track planes which extend substantially parallel relative to one another and symmetrically relative to radial planes through the first and second longitudinal axes, for first pairs of tracks, a first opening angle (α for second pairs of tracks, second opening angle (α
