Abstract

A coupling arrangement is provided with a vibration reduction device and with a clutch device. The vibration reduction device has at least one torsional vibration damper, an input connected to a drive, and an output connected to the clutch device by which a connection between the vibration reduction device and a driven end is at least substantially produced in a first operating state, and this connection is at least substantially cancelled in a second operating state. The vibration reduction device has a mass damper system that cooperates with the torsional vibration damper and is connected to the output of the vibration reduction device.

First claim

The invention claimed is:

1. A coupling arrangement comprising:
a clutch device;
a vibration reduction device comprising:
at least one torsional vibration damper;
an input which is connected to a drive; and
an output connected to the clutch device by which a connection between the vibration reduction device and a driven end is at least substantially produced in a first operating state, and this connection is at least substantially cancelled in a second operating state, wherein the output of the vibration reduction device is centered at the driven end; and
wherein the at least the output is centered with respect to a central axis, and the centering of output is carried out at the driven end;

a housing of coupling arrangement configured as the drive for the vibration reduction device; and
a mass damper system that cooperates with the at least one torsional vibration damper and connected to the output of the vibration reduction device, wherein the at least one torsional vibration damper has at least one damping unit whose output has at least two output component parts, at least one of the at least two output component parts is centered but is received so as to be rotatably movable in circumferential direction,
wherein that at least one output component has a connection to a damper mass carrier of the mass damper system, which damper mass carrier is provided for receiving damper masses, wherein the mass damper system has a friction disk coupler carrier that receives at least one friction disk coupler of the clutch device so as to be fixed with respect to rotation relative to it.

2. The coupling arrangement according to claim 1 , wherein the at least one torsional vibration damper is connected to the at least one friction disk coupler of the clutch device, which friction disk coupler is pressed against a receptacle component part fixed to the driven end for co-rotation therewith in the first operating state by a clutch piston associated with the clutch device,
wherein in the second operating state the clutch piston at least substantially releases the at least one friction disk coupler to at least partially cancel an operative connection between the at least one friction disk coupler and the receptacle component part.

3. The coupling arrangement according to claim 1 , wherein the at least one output component of the output is configured as the friction disc coupler carrier of the clutch device that receives at least one friction disk coupler of the clutch device so as to be fixed with respect to rotation relative to it.

4. The coupling arrangement according to claim 1 , wherein the at least one torsional vibration damper has a plurality of damping units of which an input-side damping unit is operatively connected via an intermediate transmission to the respective output-side damping unit,
wherein the intermediate transmission acts as input with the output-side damping unit.

5. The coupling arrangement according to claim 1 , wherein the damper mass carrier of the mass damper system has two damper mass carrier elements arranged at an axial distance from one another and connected to one another by at least one spacer piece,
wherein the at least one spacer piece acts in an auxiliary function as friction disk coupler carrier.

6. The coupling arrangement according to claim 1 ,
wherein the driven end is configured as a torsional vibration damper hub,
wherein the torsional vibration damper hub is received by at least one of:
a spline of a driven shaft, and
on the input and output of the vibration damping device.
