Abstract
A rotary vibration damper with an input part and an output part having a centrifugal force pendulum disposed on a flange part of the input part or output part, with several mass parts distributed over the circumference of the flange part, and disposed on two sides of the flange part, in raceways of the flange part, and limitedly displaceable in the circumferential direction, and in the radial direction by which two mass parts are interconnected respectively on opposite sides of the flange part.
Claims17
A rotary vibration damper, comprising:
- an input part;
- at least one output part;
- a centrifugal force pendulum disposed on a flange part of the input part or the at least one output part;
- and,
- a plurality of mass parts distributed over the circumference of the flange part and disposed on both sides of the flange part, received in a plurality of raceways of the flange part and limitedly displaceable relative to said plurality of raceways in circumferential direction and in radial direction, of which, two of the plurality of mass parts disposed on opposite sides of the flange part, are connected together, respectively, wherein in the area of the plurality of mass parts, the flange part includes a recess in which an auxiliary mass part, connected respectively with the opposite mass parts, is disposed.
