  • Patent number: 9316293
    Abstract: A friction ring-type transmission includes two roller bodies which are arranged at a distance from each other about a gap, which correspond to each other via the friction ring and which rotate (5) on axial roller body axes. The friction ring is arranged in an adjusting bridge in such a manner that it can be axially displaced about an adjusting path along the gap and the adjusting bridge is mounted by an individual, axial guiding device.

  • Publication number: 20030178757
    Abstract: The invention relates to a spring element, comprising a sprung sheet (16, 17) which co-operates with at least one rolling body (20) in a first region (23) of the device. The rolling body impinges on a stopper (22) in a second region (25) of the device and opposite to the first region of the device with the sprung sheet. The stopper and sprung sheet are mounted in a displaceable manner relative to each other and, on such a displacement, the sprung sheet is bent. The above spring element may be applied to advantage in torsional vibration dampers (1) and preferably comprises a damping unit.
