  • Patent number: 5509855
    Abstract: A constant velocity universal ball joint has an outer joint part with substantially longitudinally extending outer ball tracks and an inner joint part with substantially longitudinally extending inner ball tracks. The tracks in the outer joint part and inner joint part are positioned radially opposite one another to form a pair and, in each case, jointly receiving a torque-transmitting ball. A ball cage includes circumferentially distributed cage windows, which hold the balls in a common plane and guides them on to the angle-bisecting plane when the joint is articulated. The cage windows, if viewed in the circumferential direction, narrow at their ends. Opposed flanks of the cage windows jointly form a stop relative to the respective balls if there occurs a relative circumferential displacement between the ball cage and balls.

  • Patent number: 5507693
    Abstract: A constant velocity universal joint of the tripod type has an outer joint part with three axially extending, circumferentially distributed longitudinal recesses with circumferentially distributed opposed tracks. The tracks have surfaces which are grooved so as to have the shape of a circular cylindrical portion. An inner joint part includes three radial circumferentially distributed arms each engaging one of the longitudinal recesses and carrying roller assemblies having roller carriers and roller elements. The roller elements have running faces in the shape of a spherical portion and are axially guided so as to roll on the tracks in the longitudinal recesses of the outer joint part. The roller carriers are guided on the arms so as to be pivotable and longitudinally movable relative to the respective arm axis.

  • Patent number: 5376049
    Abstract: A tripod joint has an outer joint component having three circumferentially distributed recesses with parallel axes forming circumferentially opposing tracks. An inner joint component has a spider-shape cross-section with three circumferentially distributed arms which engage recesses of the outer joint component. The arms support roller assemblies. Each roller assembly includes a roller-carrier and a roller that runs directly on the tracks. The roller is arranged to slide axially along the arm axis and swivel with angular movement relative to the arm axis. A support is provided between the roller assembly and the outer joint component. The support absorbs tilting moments exerted on the roller assembly about an axis parallel to the joint axis and tilting moments exerted on the roller assembly about an axis perpendicular to, and spaced from, the joint axis.
