ABSTRACT:
A fixed constant velocity joint has a hollow outer part (1) whose inner face (2), relative to the longitudinal axis (4) of the outer part, is provided with outer running grooves (3). The cavity (5) of the outer part (1) contains an inner part (6) whose outer face (8) is provided with inner running grooves (7) which extend in meridian planes relative to the longitudinal axis (12) of the inner part and which are positioned opposite the outer running grooves (3). In each case, opposed inner running grooves (7) and outer running grooves (3), jointly, accommodate a ball (9) for torque transmitting purposes. The ball (9) is guided in a cage (11) arranged between the inner face (2) of the outer part (1) and the outer face (8) of the inner part (6). The cage (11), via its partial spherical face (18), is guided on an outer spherical face (14) of the inner part (6) facing away from the closed end (15) of the joint. The inner part (6) is provided with a first guiding face (30) which is designed as a hollow spherical zone, which, starting from the closed end (15), is designed to be undercut-free and whose center is positioned on the joint articulation center (13). Via a guiding element (22) with a second guiding face (29), designed as a spherical cap, the inner part (6) is axially secured as a result of the guiding element (22) resting against the supporting element (20). The guiding element (22) is displaceably supported on the supporting element (20) in the radial direction relative to the longitudinal axis (4) of the outer part.
