Abstract: A constant velocity fixed joint having an outer joint part, an inner joint part, a cage and torque transmitting balls has the cumulative clearance errors of the joint minimized via the fixing method of supporting inserts. This is achieved in that a ring is provided with at least two fingers pointing axially and radially inward into the cavity of the outer joint part and arranged between two outer running grooves so as to abut the spherical contact face of the cage. While the clearances between the internal joint components are positioned at a predetermined relationship, the ring is positioned at an axial distance from a reference face located at the open end of the outer joint part and that the ring, while observing a predetermined axial play, is connected to the outer joint part. The inner faces of the outer joint part arranged between the outer running grooves thus being held at a predetermined position relative to the spherical outer face of the cage.

Abstract: A constant velocity universal joint of the tripode type includes a roller assembly arranged on the tripode arm which is secured against unintentionally disengagement with the tripode arm. A pressure disc is provided which holds the roller assembly together as a unit and whose shape, relative to the ideal round shape, deviates radially inwardly. The radially inwardly directed deviation in shape is designed with a slightly smaller width of opening than the dimension corresponding to the maximum outer diameter of the spherical arm. In this way it is ensured that the roller assembly on the spherical tripode arm is self-holding after having been mounted.

Abstract: A constant velocity universal joint of the tripode type increases the torque transmitting capacity of the joint while the size of the joint remains unchanged, and, respectively, with a predetermined torque capacity, to reduce the size of the joint, especially the outer diameter of the joint. This is achieved in that the joint is guided entirely by the outer roller and that the securing means for the roller assembly on the tripode arm are displaced radially inwardly with reference to the joint axis.

Abstract: A viscous coupling has a housing (2) and a hub (24), and a separating wall (8). An operating chamber (33) is formed between the housing (2), hub (24) and separating wall (8). Inner plates (37) and outer plates (35) are alternately arranged in the chamber (37). A compensating chamber (34) is formed between a housing extension (3), the separating wall (8), the hub (24) and a movable wall (15) axially loaded by a spring (17). The compensating chamber (34) and the operating chamber (33) are connected to one another by a throttling bore (12). Both chambers (33, 34) are filled with a highly viscous fluid. By filling the operating chamber (33) completely by loading the compensating chamber (34) towards assuming its minimum volume, it is possible to provide a coupling with progressive characteristics which ensure a rapid coupling response and thus an improvement in vehicle traction.

The ends of the arms of the inner joint part facing the two directions of rotation of the joint arms are each provided with a face extending parallel to the longitudinal axis of the joint and to the axis of the respective arm.

The second securing mechanism is plastically formed in-situ and axially supports the hub in the direction of the shaft shank of the driveshaft.
