  • Publication number: 20120129616
    Abstract: The invention relates to a constant velocity joint having an inner race (3), an outer race (4), a journal (9) that can be connected with the outer race for connecting the joint and with a reinforcement ring (7), that can be positively connected with the outer race, which encases the outer race (4) in torque-proof manner and has at least one stop section (7a, 7b), which defines the position of the outer race (4) in the reinforcement ring (7) in a first axial direction. The journal (9) has a flange-like shoulder section (8), for example, with an axial stop surface (8a), which defines the position of the outer race (4) in the reinforcement ring (7) in a second axial direction that is opposite to the first axial direction, whereby the journal (9) is fixated on the reinforcement ring (7).

  • Patent number: 8157660
    Abstract: A rolling-sliding unit, particularly for a jointed shaft, including a profiled sleeve (4) having outer raceways on an interior surface thereof; a journal (5) which is displaceable in the profiled sleeve (4) and which has inner raceways on an exterior surface thereof, and balls (9) in the raceways between the profiled sleeve and the journal for transmitting torque. A cover is provided on the journal of the rolling-sliding unit and an elastic element is arranged between the profiled sleeve and the journal of the rolling-sliding unit. A jointed shaft comprising a rolling-sliding unit of the described type also is described.

  • Publication number: 20100227696
    Abstract: The invention relates to a displacement unit and to a universal shaft comprising said type of displacement unit. Said displacement unit comprises a tubular-type external part on whose inner surface outer paths are provided at least in sections, an inner part that can be displaced in an axial direction in the external part, on whose outer surface inner paths are arranged at least on sections, and balls that are guided in a cage, said balls being arranged for transmitting torque, respectively in outer and inner paths that are arranged in pairs. The external part and/or the inner part comprise cage guide paths for displacing the cage axially, arranged between at least a few of the outer paths or the inner paths. The number of cage guide paths is smaller than the number of pairs of paths formed by the outer paths and the inner paths.

  • Patent number: 7691001
    Abstract: A method for producing a joint connection for torque-transmitting connection of a component (1) provided with spur gear teeth (13) with a constant velocity joint (2) provided with corresponding spur gear teeth (11). The spur gear teeth can be brought into interengagement by applying an axial engaging force and have flanks (25) that contact each other as functional surfaces. The invention also relates to a joint connection of the aforementioned type.
