Abstract: A counter track joint comprises an outer joint part, an inner joint part, first pairs of tracks widening towards the opening side of the outer joint part when the counter track joint is aligned, and second pairs of tracks widening towards the connecting side of the outer joint part when the counter track joint is aligned; a ball in each of the first and second pairs of tracks; a ball cage having circumferentially distributed cage windows each receiving one of the balls, wherein one of the outer ball track group and the inner ball track group is hardened and hard machined, and the other of the outer ball track group and the inner ball track group is soft finished and subsequently hardened. A method of manufacturing a counter track joint is provided.

Abstract: A constant velocity joint comprises an outer joint part with outer ball tracks, an inner joint part with inner ball tracks, wherein respectively an outer ball track and an inner ball track form a pair of tracks with each other; a torque-transmitting ball in each pair of tracks; a ball cage in which the torque-transmitting balls are received; wherein a first articulation angle range is defined comprising articulation angles of less than twenty degrees, and a second articulation angle range comprising articulation angles greater than twenty degrees; wherein an opening angle within the first articulation angle range increases as the articulation angle (?) increases, and wherein a first mean opening angle increase of the first articulation angle range is greater than a second mean opening angle increase of the second articulation angle range.

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 ball 14 in each pair of tracks, and a ball cage 15 with cage windows 18 in which the balls 14 are held. In each angular position of the constant velocity joint 11 an 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.
