Abstract

A torque transmission unit which has a first centrifugal mass that can be non-rotatably associated with an internal combustion engine and a second centrifugal mass that is connected downstream of the first mass and can be associated with a transmission. The second centrifugal mass has a rotor of an electric machine for transmitting a torque that can be electrically generated to the second centrifugal mass and a centrifugal force pendulum for reducing torsional vibrations.

Claims (12)

1. A torque transmission unit, comprising:

a first centrifugal mass non-rotatably assignable to an internal combustion engine; and

a second centrifugal mass connected downstream of the first centrifugal mass and assignable to a gear unit, the second centrifugal mass including an electric machine with a rotor for transmitting an electrically producible torque onto the second centrifugal mass, and a centrifugal force pendulum device for reducing rotary vibrations, the centrifugal force pendulum device having a carrier flange and at least one pendulum mass, the carrier flange being fixed with respect to rotation relative to the rotor.

2. The torque transmission unit according to claim 1 , further comprising an energy storage device, wherein the first centrifugal mass and the second centrifugal mass are rotatable relative to each other by the energy storage device.

3. The torque transmission unit according to claim 2 , further comprising a separating clutch connected between the first centrifugal mass and the second centrifugal mass.

4. The torque transmission device according to claim 3 , further comprising a third centrifugal mass assigned to the second centrifugal mass via the energy storage device, the third centrifugal mass being rotatable relative to the second centrifugal mass for storage or release of energy.

5. The torque transmission device according to claim 4 , wherein the third centrifugal mass is assignable to or separated from the first centrifugal mass by the separating clutch.

6. The torque transmission device according to claim 1 , wherein the second centrifugal mass has an intermediate shaft and the centrifugal force pendulum device is arranged radially outside of the intermediate shaft.

7. The torque transmission device according to claim 1 , further comprising one of a start-up clutch, a standard transmission, a stepped automatic gear unit, a stepped automatic gear unit with converter, a double clutch gear unit, and a CVT gear unit, wherein the one of the start-up clutch, the standard transmission, the stepped automatic gear unit, the stepped automatic gear unit with converter, the double clutch gear unit, and the CVT gear unit is connected downstream of the second centrifugal mass.

8. The torque transmission device according to claim 1 , further comprising a rigid flywheel, wherein the centrifugal force pendulum device is arranged axially adjacent to the rigid flywheel.

9. The torque transmission device according to claim 8 , wherein the rigid flywheel is a counter pressure plate of a start-up clutch.

10. The torque transmission device according to claim 9 , wherein the centrifugal force pendulum device is arranged axially between the start-up clutch and the electric machine.
