A device for damping vibrations, especially a torsional vibration damper, comprising at least one primary part and a secondary part that are coaxial in relation to each other and limited rotatably relative to each other in a peripheral direction, whereby the primary part and secondary part (4) are coupled with each other by means for transmitting torque and means for damping coupling, and the secondary part can be at least indirectly coupled to a connecting element, especially a transmission input shaft. A ramp is provided that is at least indirectly connected to the secondary part, extends in a peripheral direction over a section, has an axially changing slope and acts on at least one counter element braced against a connecting element via a pretensioning unit.
A device (2) for damping vibrations, especially a torsional vibration damper, 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 (5) for transmitting torque and means (6) for damping coupling, and the secondary part (4) can be at least indirectly coupled to a connecting element, especially 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) via a pretensioning unit (11).
A force transmission device (1) for use in motor vehicles with one input and at least one output, comprising a hydrodynamic component and a device (LU) for bridging the hydrodynamic component, and at least one device (2) for damping vibration said device for damping vibration 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 (5) for transmitting torque and means (6) for damping coupling, and the secondary part (4) can be at least indirectly coupled to a connecting element, especially 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) via a pretensioning unit (11).
