Abstract
A constant velocity joint comprises an outer joint part with a longitudinal axis and first and second outer ball tracks. The outer joint part comprises an attachment side and an aperture side. An inner joint part has a longitudinal axis and first and second inner ball tracks. with a torque transmitting ballin each pair of tracks, and a ball cagewith cage windowsin which the ballsare held. In each angular position of the constant velocity jointan opening angle is enclosed between an outer tangent and an inner tangent at the ball. At least one of the first and second pairs of tracks is designed such that, within a small articulation angle range comprising at least the joint central plane, at at least an articulation angle, an opening angle amounts to zero, and within a greater articulation angle range, an aperture-side opening angle of a first pair of tracks widens in the opposite axial direction relative to the aperture-side opening angle of a second pair of tracks.
