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 (M1, M2) 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 (Lm) of the cage windows (12, 42). The center of curvature (M1) 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 (M2) 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).

A constant velocity universal ball joint comprising: an outer joint part with longitudinally extending, internally circumferentially distributed first ball tracks; an inner joint part with longitudinally extending, externally circumferentially distributed second ball tracks, with one first ball track and one second ball track each arranged so as to be radially opposed; an aperture, on at least one end of said outer joint part, said aperture providing clearance for a drive member connectable to the inner joint part; torque transmitting balls each guided in said first and said second ball track; an annular ball cage positioned in an annular chamber between the outer joint part and the inner joint part, said cage including circumferentially distributed cage windows each axially holding a respective one of the torque transmitting balls said ball cage holds all the torque transmitting balls in one common plane, and when the axes of the outer joint part and of the inner joint part are articulated, said cage guides said balls onto the angle-bisecting plane of said axes, and said cage includes an outer spherical cage face which is in guiding contact with guiding faces associated with the outer joint part, and an inner spherical cage face which is in guiding contact with a surface of the inner joint part, and centers of curvature of the outer spherical face and of the inner spherical face of the ball cage are axially offset relative to a central cage plane, defined by circumferentially extending center lines of the cage windows, with the center of curvature of the outer spherical face positioned towards the aperture in the outer joint part and the center of curvature of the inner spherical face being positioned towards the end of the outer joint part located axially opposite the aperture, and the inner diameter of the opening of the ball cage, which is closest to the aperture of the outer joint part, is greater than the greatest outer diameter of the surface of the inner joint part, so that the inner joint part can be coaxially assembled with the ball cage.
