  • Thrust bearing comprising a spacing member
    Patent number: 7318676
    Abstract: An axial bearing having at least one axial runner disk which has a radially extending portion and an axially extending annular flange. A plurality of rollers roll along the radially extending portion of the axial runner disk. A detachable spacing member of annular shape retained on the axial runner disk with the aid of fastening elements, forming a captive axial bearing arrangement. The annular spacing member has a plurality of spaced-apart projecting bosses arranged in the circumferential direction having an axial extent determined by predefined spacing between two connection parts. A second axial runner disk cooperates with the first disk and holds bearing rollers between them. The bearing may be employed in a hydrodynamic torque converter at the stator between the pump wheel and the turbine wheel of the converter.

  • Shifting device for a speed change gearbox, with a damping component and a shift path limit
    Patent number: 6658959
    Abstract: A shifting device (1) for a speed change gearbox with a transmission component that can be shifted in a longitudinal direction and/or about its longitudinal axis in a pivoting manner, which for transmitting the shifting movements is equipped with a damping component (8), which is constructed from at least one ramp-shaped profile (9a), and at least one roller component (12) which is pre-loaded against ramp-shaped profile (9a) by means of spring action.

  • Rolling bearing cage
    Patent number: 6261005
    Abstract: The invention concerns a rolling bearing cage (1, 21) made of a resilient plastic and comprising at at least one peripheral point, an axially extending gap (2) formed by a first cage end (4) and a second cage end (3) which is spaced from the first cage end (4), each of the first and the second cage ends (4, 3) comprising at least one projection and at least one recess, said recess and projection having complementary shapes, and as viewed in axial direction, the recess and the projection partially engage each other, and as viewed in peripheral direction, the recess and the projection partially overlap each other.
