Abstract

A constant velocity joint comprises an outer joint part with a 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 longitudinal axis and inner ball tracks; a torque transmitting ball in each pair of tracks; a ball cage with cage windows in which the balls are held, wherein in each angular position of the constant velocity joint there is enclosed an opening angle δ between an outer tangent T and an inner tangent T′ at the ball, wherein at least one of the pairs of tracks is designed such that, inside a small articulation angle range, which comprises at least the joint central plane EM, in at least one joint articulation angle β, an opening angle δ amounts to zero, and that inside a larger articulation angle range, an aperture side opening angle δ of a ball moving towards the aperture side of the outer joint part and an attachment side opening angle δ of a ball moving at the same joint articulation angle β towards the attachment side of the outer joint part do not equal zero and open in the same axial direction.
