Counter track joint with control angle reversal

A constant velocity joint in the form of a counter track joint comprising:

• an outer joint part (12) comprising a first longitudinal axis (La), an attaching end and an aperture end which are positioned axially opposite one another, as well as first outer ball tracks (22) and second outer ball tracks (24);
• an inner joint part comprising a second longitudinal axis (Li), an attaching mechanism for a shaft pointing towards the aperture end of the outer joint part (12), as well as first inner ball tracks (23) and second inner ball tracks (25), the first outer ball tracks (22) and the first inner ball tracks (23) form first pairs of tracks with one another, the second outer ball tracks (24) and the second inner ball tracks (25) form second pairs of tracks with one another, and the first and second pairs of tracks each accommodate a torque transmitting ball (14);
• and
• a ball cage (15) positioned between the outer joint part (12) and the inner joint part (13) including circumferentially distributed cage windows (18) which each receive at least one of the torque transmitting balls (14);
• wherein the centers of the balls (14) are held by the cage (15) in a central ball plane (EK), and the travel of the centers of the balls (14) in the ball tracks is defined as the center line (M22, M23, M24, M25) of the respective ball tracks;
• when the joint is in the aligned condition, an opening angle (α) of the first pairs of tracks (22, 23) opens from the aperture end to the attaching end;
• when the joint is in the aligned condition, an opening angle (β) of the second pairs of tracks (24, 25) opens from the attaching end to the aperture end;
• and
• wherein the track center lines (M22) of the first outer ball tracks (22) of the first pairs of tracks, centrally, comprise a first arch with a first radius (R2) whose center is offset by a first axial offset (O1) from the central plane (EM) of the joint towards the attaching end and wherein, adjoining said first arch, towards the attaching end, they increasingly deviate radially inwardly from said arch having said first radius (R2) and wherein the track center lines (M23) of the first inner ball tracks (23) of the first pairs of tracks, centrally, comprise a second arch with a second radius (R2′) whose center is offset by a second axial offset (O2) from the central plane (EM) of the joint towards the aperture end, and wherein, adjoining said second arch towards the aperture end, they increasingly deviate radially inwardly from said arch having said second radius (R2′).
