Abstract

Various embodiments may include a clutch assembly comprising: a first coupling and a second coupling; and a vibration damper with a spring. The first coupling includes a crankshaft connection and a coupling-in element which can be connected to one another in a controlled manner. The second coupling has an output connection and an intermediate element which can be connected to one another in a controlled manner. The spring connects the intermediate element and the coupling-in element to one another.

First claim

What is claimed is:

1. A clutch assembly comprising:
a first coupling and a second coupling; and
a vibration damper with a spring;
wherein the first coupling includes a crankshaft connection and a coupling-in element which can be connected to one another in a controlled manner;
wherein the coupling-in element comprises a belt running surface or a portion of a rotor of an electrical machine;
the second coupling has an output connection and an intermediate element which can be connected to one another in a controlled manner;
wherein the spring connects the intermediate element and the coupling-in element to one another.

2. The clutch assembly as claimed in claim 1 , wherein:
the vibration damper comprises a dual-mass flywheel;
the crankshaft connection includes a mass comprising a primary mass of the dual-mass flywheel;
the intermediate element includes a mass comprising a secondary mass of the dual-mass flywheel; and
the spring comprises a spring element of the dual-mass flywheel connecting the primary mass to the secondary mass.

3. The clutch assembly as claimed in claim 1 , wherein the crankshaft connection comprises an additional flywheel mass wheel connected to the crankshaft connection for rotation therewith, or the crankshaft connection includes a portion with a flywheel mass.

4. The clutch assembly as claimed in claim 1 , wherein the intermediate element comprises an additional flywheel mass wheel connected to the intermediate element for rotation therewith, or the output connection includes a portion with a flywheel mass.

5. The clutch assembly as claimed in claim 1 , wherein the belt running surface or the portion of a rotor reaches peripherally around the remaining coupling-in element, the spring, and the intermediate element at least for the most part.

6. The clutch assembly as claimed in claim 1 , wherein the first coupling and the second coupling comprise friction couplings or dog couplings.

7. The clutch assembly as claimed in claim 1 , wherein the first coupling and the second coupling in each case include an associated actuator displaceable in an axial direction of the clutch assembly, and the position of the respective actuator defines an operating state of the respective coupling.

8. A vehicle drive train comprising:
a combustion engine;
an electrical drive;
an output;
a crankshaft; and
a clutch assembly comprising:
a first coupling and a second coupling; and
a vibration damper with a spring;
wherein the first coupling includes a crankshaft connection and a coupling-in element which can be connected to one another in a controlled manner;
the second coupling has an output connection and an intermediate element which can be connected to one another in a controlled manner;
wherein the spring connects the intermediate element and the coupling-in element to one another;
wherein the crankshaft is connected to a crankshaft connection of the combustion engine;
the electrical drive is connected to the coupling-in element and the output is connected to the output connection.

9. A vehicle drive train comprising:
a clutch assembly comprising:
a first coupling and a second coupling; and
a vibration damper with a spring;
wherein the first coupling includes a crankshaft connection and a coupling-in element which can be connected to one another in a controlled manner;
the second coupling has an output connection and an intermediate element which can be connected to one another in a controlled manner;
wherein the spring connects the intermediate element and the coupling-in element to one another;
a control device connected to the clutch assembly in an activating manner and configured to set the clutch assembly according to one of the following states of the control device:
a starting state, in which the first coupling is closed and the second coupling is open;
a recuperation state, in which the first coupling is open and the second coupling is closed;
a driving state, in which the first coupling is closed and the second coupling is closed.
