  • Patent number: 9068639
    Abstract: An arrangement for supporting an input gear of a transmission in a motor vehicle, in particular a ring gear, characterized in that a pot-shaped support element (1) is provided, whereby a drive gear to drive the input gear engages into a recess (2) of the support element (1), and, for purposes of bearing the input gear, the support element (1) extends at least partially underneath the input gear radially on the inside.
    Type: Grant

  • Patent number: 8950289
    Abstract: A controlled axial biasing unit (1) is provided which substantially includes a first ramp disk (11) and a second ramp disk (12), each of which disks is configured with a plurality of ramp contours (8). An annular cage (2) that carries a plurality of rolling elements (3) is inserted between the first ramp disk (11) and the second ramp disk (12). At least the first ramp disk (11), the second ramp disk (12) and the cage (2) are made by a shaping method without chip removal. Each of the first ramp disk (11) and the second ramp disk (12) is configured with a continuous wall (32). Likewise through this shaping method, the first ramp disk (11) and the second ramp disk (12) have on an outer periphery (UA) an integrally formed safety stop device (14) for respective end positions.

  • Patent number: 8690445
    Abstract: A rolling bearing arrangement, which has at least one angular contact rolling bearing arranged within a housing and at least one lash compensation element that is supported axially in one direction on the housing and is capable of being biased against a bearing ring of the angular contact rolling bearing with the bearing ring being axially movable relative to the housing, and a U-shaped ring which has two radially opposing legs directed in an axial direction. The U-shaped ring rendering the lash compensation element radially immovable by positive engagement while being guided on the bearing ring of the angular contact rolling bearing for axial displacement relative to the bearing ring, and the axial section of the bearing ring projecting axially between the legs of the ring profile.

  • Patent number: 8627734
    Abstract: A prestressing unit which has a first ramp disk and a second ramp disk. Ramp contours are formed in one side of an annular face of the ramp disks. In the prestressing unit, the rolling bodies ascend and/or descend on the ramp contours as a result of rotational pivoting of one of the ramp disks in relation to the other ramp disk about an axis. The ramp contours are each formed as a single-part running face for the rolling bodies. The running face is inclined with respect to the axis.
