Abstract:
1. A centrifugal pendulum mechanism, comprising: a pendulum flange including a plurality of first curved guide cutouts and a plurality of second curved guide cutouts; a first pendulum mass including: a second pendulum mass including: a plurality of spacing bolts disposed in the plurality of first curved guide cutouts; first and second rollers accommodated in the third and fourth curved guide cutouts, rollable in the third and fourth curved guide cutouts, and accommodated in respective second curved guide cutouts; third and fourth rollers accommodated in the fifth and sixth curved guide cutouts, rollable in the fifth and sixth curved guide cutouts, and accommodated in respective second curved guide cutouts; a first damping element disposed in the keyed fit for the first pendulum mass, extending from the first side surface in a second circumferential direction, opposite the first circumferential direction, and having a third extent in the radial direction; and, a second damping element extending from the second side surface in the first circumferential direction and having a fourth extent in the radial direction, wherein: the first pendulum mass is guided relative to the flange by the first and second rollers; the second pendulum mass is guided relative to the flange by the third and fourth rollers; the first extent is greater than the third extent; and, the second extent is greater than the fourth extent.
