Abstract:
1. A device ( 2 ) for damping vibrations comprising at least one primary part ( 3 ) and a secondary part ( 4 ) that are coaxial in relation to each other and limited rotatably relative to each other in a peripheral direction, whereby the primary part ( 3 ) and secondary part ( 4 ) are coupled with each other by means ( 32 ) for transmitting torque and damping vibrations, and the secondary part ( 4 ) includes a flange, and the flange is directly coupled with limited rotational play to a hub that is directly non-rotationally coupled to a transmission input shaft ( 14 ), wherein a ramp ( 8 ) is provided that is at least indirectly connected to the secondary part ( 4 ) and extends axially in a peripheral direction over a section and has an axially changing slope and acts on at least one counter element ( 9 , 9 . 1 , 9 . 11 , 9 . 12 , 9 . 3 , 9 . 4 ) mounted so as to be axially displaceable and braced against a connecting element ( 13 ) of the hub via a pretensioning unit ( 11 ), wherein the pretensioning unit acts to press the counter element axially toward the ramp, and wherein the at least one counter element is axially moveable along the hub and directly non-rotationally coupled to the hub.
