Abstract:
1. A constant velocity joint, comprising: an outer joint part with a first longitudinal axis and outer ball tracks, wherein the outer joint part comprises an attachment side and an aperture side; an inner joint part with a second longitudinal axis and inner ball tracks, wherein the outer ball tracks and the inner ball tracks form pairs of tracks; a torque transmitting ball in each pair of tracks; a ball cage arranged between the outer joint part and the inner joint part, and comprising circumferentially distributed cage windows, each of which receives at least one of the torque transmitting balls; wherein the ball cage holds the balls in a joint central plane when the inner joint part is arranged coaxially relative to the outer joint part, and wherein the first longitudinal axis of the outer joint part and the second longitudinal axis of the inner joint part form a joint articulation plane when the inner joint part is articulated relative to the outer joint part by an articulation angle which deviates from zero degrees; wherein in each angular position of the constant velocity joint an opening angle is formed between an outer tangent to the outer ball track and an inner tangent to the inner ball track when viewed in the joint articulation plane, wherein said outer tangent extends through an outer contact point between the ball and the outer ball track and wherein said inner tangent extends through an inner contact point between the ball and the inner ball track; wherein at least one of the pairs of tracks is configured such that:
