Abstract

A hybrid module for a drive train of a motor vehicle, comprises an electric machine which has a stator and a rotor, a torsional vibration damper which has at least one rotary component, and an integrated clutch device which is constructed as a dual clutch. A rotor carrier which receives the rotor is connected directly via a permanent rotary connection to the at least one rotary component. The rotor carrier forms a clutch component of at least one part-clutch of the clutch device.

First claim

The invention claimed is:

1. A hybrid module for a drive train of a motor vehicle, comprising: an electric machine having a stator and a rotor, a torsional vibration damper having at least one rotary component, and an integrated clutch device which is constructed as a dual clutch having a first part-clutch and a second part-clutch, wherein a rotor carrier which receives the rotor is connected directly via a permanent rotary connection to the at least one rotary component, wherein the rotor carrier forms a clutch component of the first part-clutch and the second part-clutch of the clutch device.

2. The hybrid module as claimed in claim 1 , wherein the torsional vibration damper has a first rotary component which forms a primary mass and a second rotary component which forms a secondary mass, wherein the two rotary components can be rotated relative to each other by a specific adjustment range and the rotary connection is formed between the second rotary component and the rotor carrier.

3. The hybrid module as claimed in claim 2 , wherein the first rotary component is prepared for rotationally secure fitting to an output shaft of an internal combustion engine so that a torque can be absorbed by the internal combustion engine and by the rotor carrier via the first rotary component and the second rotary component.

4. The hybrid module as claimed in claim 1 , wherein the torsional vibration damper is formed by combining a bow spring damper and a speed-adaptive damper.

5. The hybrid module as claimed in claim 1 , wherein the electric machine is fluid-cooled.

6. The hybrid module as claimed in claim 1 , wherein the rotary connection is constructed as a plug-in tooth arrangement.

7. The hybrid module as claimed in claim 1 , wherein the dual clutch is constructed to be fluid-cooled, wherein there is provided a fluid distributor unit which serves to support the rotor carrier.

8. The hybrid module as claimed in claim 1 , wherein the dual clutch is provided with a separately controllable fluid cooling.

9. The hybrid module as claimed in claim 1 , wherein a rotor position sensor which detects a rotation position of the rotor or a temperature sensor is/are provided.

10. A drive train for a motor vehicle having a hybrid module as claimed in claim 1 and an internal combustion engine, wherein an output shaft of the internal combustion engine is connected to the torsional vibration damper in a rotationally secure manner.
