CENTRIFUGAL FORCE PENDULUM DEVICE
A centrifugal force oscillating device having oscillating masses that are situated axially on both sides of an oscillating mass carrier rotatable around an axis of rotation and form an oscillating mass pair, where the oscillating masses can be swiveled to a limited extent along an oscillation path opposite the oscillating mass carrier with the help of at least one roll-off element that can be rolled off in cut-outs in both the oscillating mass carrier and the oscillating masses, and where the oscillating masses can be moved to a limited extent axially relative to each other to form the oscillating mass pair, and where the oscillating masses of an oscillating mass pair are movable to a limited extent radially and/or circumferentially relative to each other.
1 . A centrifugal force oscillating device ( 10 ) having oscillating masses ( 20 ) that are situated axially on both sides of an oscillating mass carrier ( 12 ) rotatable around an axis of rotation and form an oscillating mass pair, where the oscillating masses ( 20 ) can be swiveled to a limited extent along an oscillation path opposite the oscillating mass carrier ( 12 ) with the help of at least one roll-off element ( 26 ) that can be rolled off in cut-outs ( 28 , 30 ) in both the oscillating mass carrier and the oscillating masses, and where the oscillating masses ( 20 ) can be moved to a limited extent axially relative to each other to form the oscillating mass pair, wherein the oscillating masses ( 20 ) of an oscillating mass pair are movable to a limited extent radially and/or circumferentially relative to each other.
2 . The centrifugal force oscillating device ( 10 ) as recited in claim 1 , wherein the roll-off element ( 26 ) accommodates a retainer ( 36 ) on the side lying axially outside in relation to the oscillating mass ( 20 ), to limit maximum axial movement of the oscillating masses ( 20 ) of an oscillating mass pair relative to each other.
3 . The centrifugal force oscillating device ( 10 ) as recited in claim 2 , wherein the retainer ( 36 ) is situated firmly on the roll-off element ( 26 ).
4 . The centrifugal force oscillating device ( 10 ) as recited in claim 2 , wherein the retainer ( 36 ) is designed as a ring-shaped element.
5 . The centrifugal force oscillating device ( 10 ) as recited in claim 2 , wherein the retainer ( 36 ) is secured axially in at least one direction by a locking ring ( 38 ) accommodated in a recess ( 40 ) in the roll-off element ( 26 ).
6 . The centrifugal force oscillating device ( 10 ) as recited in claim 2 , wherein the retainer ( 36 ) is movable circumferentially and/or radially together with the roll-off element ( 26 ), relative to the oscillating mass ( 20 ).
7 . The centrifugal force oscillating device ( 10 ) as recited in claim 1 , wherein a minimum axial distance between the oscillating masses ( 20 ) and the oscillating mass carrier ( 12 ) is defined by an axial projection formed on the oscillating mass carrier ( 12 ) and/or on the lateral face of the oscillating mass ( 20 ) that faces the oscillating mass carrier ( 12 ) axially.
8 . The centrifugal force oscillating device ( 10 ) as recited in claim 7 , wherein the axial projection is made in a single piece with the oscillating mass carrier ( 12 ) or the oscillating mass ( 20 ).
9 . The centrifugal force oscillating device ( 10 ) as recited in claim 1 , wherein a minimum axial distance between the oscillating masses ( 20 ) and the oscillating mass carrier ( 12 ) is defined by a collar formed on the roll-off element ( 26 ) and located axially in each case between oscillating mass ( 20 ) and oscillating mass carrier ( 12 ) and encircling the roll-off element ( 26 ).
10 . The centrifugal force oscillating device ( 10 ) as recited in claim 1 , wherein the oscillating masses ( 20 ) of an oscillating mass pair are received exclusively on the oscillating mass carrier ( 12 ) with the help of the roll-off element ( 26 ).
