  • Publication number: 20130239746
    Abstract: A rotational speed-adaptive centrifugal force pendulum for a shaft that can be rotated about an axis, having a pendulum flange on which at least two axially opposite absorber masses that are connected to each other via a spacing element are arranged. The absorber masses and/or the pendulum flange of the centrifugal force pendulum have at least one cutout in which the spacing element of the absorber mass is guided. The cutout is designed as a curve that deviates from a circle or a circular segment starting from a neutral position, by a radius increase of the cutout in one region starting from the neutral position and by a radius reduction of the cutout in the other region starting from the neutral position.

  • Patent number: 8156842
    Abstract: The invention relates to a rotary oscillation damper having an input part and an output part which can be moved relatively and to a limited extent with respect thereto against the influence of at least one energy store. The at least one energy store is in this case supported on one side on a counter bearing and on its other side acts on in each case at least one movement profile, which runs in the circumferential direction, of the input part and output part, in such a manner that, during a relative rotation of the input part and output part with respect to one another, the energy store absorbs energy, and emits it again when the relative rotation is reversed.
