Abstract

A hybrid module for a powertrain includes a drive, a first coupling section that couples the hybrid module to a transmission, and a second coupling section that couples the hybrid module to an internal combustion engine. The second coupling section includes a shifting arrangement having at least two shift elements which can take an initial and a shift position.

First claim

What is claimed is:

1. A hybrid module for a drive train, comprising:
a drive;
a first coupling section that couples the hybrid module to a transmission;
a clutch that is associated with the first coupling section; and
a second coupling section that couples the hybrid module to an internal combustion engine, wherein
the second coupling section comprises a shifting system having at least two shifting elements, which assume a starting position and a shifting position.

2. The hybrid module according to claim 1 , wherein a damping system for torsional vibrations is provided, which comprises a dual mass flywheel and/or a centrifugal pendulum.

3. The hybrid module according to claim 1 , wherein the shifting system comprises an actuator, which actuates at least one of the shifting elements, and in particular actuates the same electrohydraulically or electromechanically.

4. The hybrid module according to claim 3 , wherein the shifting elements are coupled in a chamber in which a lubricant is accommodated.

5. The hybrid module according to claim 4 , wherein the shifting elements are designed in a form-locked manner with respect to each other as claw elements.

6. The hybrid module according to claim 5 , wherein the shifting elements have a substantially cylindrical design, in the shifting position, the one shifting element at least partially surrounds the other shifting element peripherally.

7. The hybrid module according to claim 6 , wherein the shifting elements are provided with friction surfaces, which cooperate with each other in the shifting position.

8. The hybrid module according to claim 7 , wherein the shifting system comprises at least one spring element, which is provided between one of the shifting elements and the damping system.

9. The hybrid module according to claim 8 , wherein the coupling sections are designed as part of a keyed joint.

10. The hybrid module according to claim 9 , wherein shiftable freewheeling is provided.

11. The hybrid module according to claim 1 , wherein the drive is an electric drive.
