Constant velocity fixed ball joint with a multi-component outer joint part

A constant velocity fixed ball joint (11) having a longitudinal axis (A) and comprising:

• an outer joint part (12) with an annular member (13) and a joint base (14) which is produced separately from, and is connected to, the annular member (13);
• an inner joint part (23) which is axially supported directly or by way of a cap (42) or disc (40) on the joint base (14) of the outer joint part (12);
• first ball tracks (22) in the outer joint part (12) and second ball tracks (25) in the inner joint part (23) which first ball tracks and second ball tracks (22, 25) are positioned in planes extending through the longitudinal axis (A) and which comprise curved center lines;
• balls (16) which run in pairs of first ball tracks (22) and second ball tracks (25) associated with one another said pairs of first ball tracks (22) and second ball tracks (25) widening towards a joint aperture (26) axially opposite the joint base (14);
• a cage (17) which comprises circumferentially distributed cage windows (18) for receiving balls (16) and which holds said balls (16) in a common plane,
• wherein the cage (17) is axially form-fittingly held in both directions in an inner face in the outer joint part (12),
• and wherein, in a first axial direction towards the joint base (14), the inner joint part (23) is unsupported relative to the cage (17), and in a second axial direction towards the joint aperture (26), the inner joint part (23) is indirectly supported via the cage (17) on the outer joint part (12),
• and wherein the cross-section of the inner joint part (23) is smaller than a base aperture in the annular member (13) provided for the joint base (14),
• and wherein the joint base (14) is fixed in the base aperture in the annular member (13).
