Abstract

A constant velocity fixed ball joint (11) having a longitudinal axis (A), an outer joint part (12) with an annular member (13) and a joint base (14), an inner joint part (23) which is axially supported on the joint base (14), and a cage (17) for receiving the balls (16) and holding the balls (16) in a common plane. The cage (17) is held in both directions on an inner face in the outer joint part (12). The inner joint part (23), in a first direction, is unsupported relative to the cage (17). 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). The cross-section of the inner joint part (23) is smaller than the base aperture in the annular member (13) for the joint base (14).
