Abstract
A constant velocity universal ball joint has an outer joint part, an inner joint part and torque transmitting balls held in a cage. The cage has centers of curvature (M.sub.1, M.sub.2) of the outer spherical face (14, 44) and of an inner spherical face (14, 44) of the ball cage (4, 34) which are axially offset relative to a central cage plane (E), defined by the circumferentially extending center lines (L.sub.m) of the cage windows (12, 42). The center of curvature (M.sub.1) of the outer spherical face (13, 43) is positioned towards the aperture (8, 38) in the outer joint part (2, 32), and the center of curvature (M.sub.2) of the inner spherical face, (14, 44), is positioned towards the end of the outer joint part (2, 32) located axially opposite the aperture (8, 38). The diameter of the inner aperture (15, 45) of the ball cage (4, 34), which is positioned towards the aperture (8, 38) of the outer joint part (2, 32), is greater than the greatest outer diameter of the surface (19, 49) of the inner joint part (3, 43).
