Einrichtung zum Kompensieren von Drehstößen

摘要

The invention relates to an apparatus for compensating for rotational impulses, especially torque variations in an internal combustion engine, by means of at least two gyratory masses (3,4) which are arranged coaxially with respect to each other and are capable of limited relative rotation against the action of a damping device (13). The gyratory mass (3) may be connected to the internal combustion engine and the mass (4) to the input part (10) of a gearbox. The damping device consists of circumferentially acting force accumulators and/or frictional or sliding means, and at least one further damping device (14) is provided, in addition to the said damping device, in the torque transmission path between the gyratory masses. Both damping devices each have, at least two disks (37,38; 24,25) arranged in axially spaced-apart relationship, each set of disks being fixed for rotation with a different one of the gyratory masses, and a common intermediate flange (29) which is operative between both pairs of disks being provided for the transmission of torque between the first damping device and the further damping device.
