Abstract

A hybrid module for a vehicle arranged in a drivetrain between a drive unit, particularly an internal combustion engine, and an output, wherein an electric machine is provided, a rotor of the electric machine is connected to the output, and a clutch is provided between the drive unit and the electric machine, characterized in that the clutch is formed as a cone clutch.

First claim

The invention claimed is:

1. A hybrid module for a vehicle arranged in a drivetrain between a drive unit and an output, comprising:
an electric machine;
a rotor of the electric machine is connected to the output, and
a clutch is provided between the drive unit and the electric machine, wherein the clutch is a cone clutch, wherein the cone clutch comprises:
at least one outer friction ring connected to the rotor; and
one intermediate friction ring formed in a segmented manner.

2. The hybrid module according to claim 1 , wherein a torsional damper is arranged between the drive unit and the electric machine upstream or downstream of the clutch.

3. The hybrid module according to claim 1 , wherein the cone clutch is operatively connected on a driven side to a torque converter.

4. The hybrid module according to claim 1 , wherein the cone clutch has only one friction surface.

5. The hybrid module according to claim 1 , wherein the outer friction ring is integrally formed with a rotor carrier of the rotor.

6. The hybrid module according to claim 1 , further comprising:
a connection plate provided on a driving side, and wherein the intermediate friction ring is connected to the connection plate by positive engagement in circumferential direction and is axially moveable relative to the connection plate.

7. A hybrid module for a vehicle arranged in a drivetrain between a drive unit and an output, comprising:
an electric machine;
a rotor of the electric machine is connected to the output, and
a clutch is provided between the drive unit and the electric machine, wherein the clutch is
a cone clutch, wherein the cone clutch comprises:
at least one outer friction ring connected to the rotor; and
one intermediate friction ring;
an inner friction ring; and
wherein the outer friction ring and the inner friction ring are arranged to be fixed with respect to rotation relative to one another.

8. The hybrid module according to claim 7 , wherein the intermediate friction ring is formed in a segmented manner.

9. The hybrid module according to claim 1 , wherein the cone clutch is formed as normally open.

10. The hybrid module according to claim 1 , wherein the cone clutch is formed with at least one inserted friction lining that is not fixedly connected to another component part of the cone clutch.

11. The hybrid module according to claim 7 , further comprising:
a piston formed integrally with the inner friction ring and configured to actuate the cone clutch.

12. The hybrid module according to claim 1 ,
for a normally open type cone clutch, the cone clutch tapers in direction of piston actuation, and
for a normally closed type cone clutch, the cone clutch tapers opposite the direction of piston actuation.

13. The hybrid module according to claim 1 , further comprising an oil baffle provided at the cone clutch.

14. The hybrid module according to claim 1 , wherein, for directing oil, a portion of an oil flow is guided through the open cone clutch, and the portion of the oil flow is interrupted when the cone clutch is actuated.

15. The hybrid module according to claim 1 , wherein the drive unit is an internal combustion engine.
