Abstract

A hybrid module for a powertrain of a motor vehicle includes an electric machine, a clutch device, and a frictionally-engaging separating clutch. The separating clutch is arranged between a dual-mass flywheel and an intermediate shaft. The separating clutch includes a counter-plate, an outer lamella carrier rigidly connected to the counter-plate, a pressure plate, axially movable relative to the outer lamella carrier, an intermediate plate, axially movable relative to the outer lamella carrier, a first clutch disk, axially movable and extending between the pressure plate and the intermediate plate, and a second clutch disk, axially movable and extending between the counter-plate and the intermediate plate. The pressure plate or the intermediate plate is connected to the outer lamella carrier for conjoint rotation therewith via a leaf spring, or the pressure plate or the intermediate plate is connected to the counter-plate for conjoint rotation therewith via a leaf spring.

First claim

1 .- 9 .(canceled)

10 . A hybrid module for a powertrain of a motor vehicle, comprising:
an electric machine; a clutch device; and a frictionally-engaging separating clutch arranged between a dual-mass flywheel and an intermediate shaft, comprising:
a counter-plate;
an outer lamella carrier rigidly connected to the counter-plate;
a pressure plate, axially movable relative to the outer lamella carrier;
an intermediate plate, axially movable relative to the outer lamella carrier;
a first clutch disk, axially movable and extending between the pressure plate and the intermediate plate; and
a second clutch disk, axially movable and extending between the counter-plate and the intermediate plate, wherein:
the pressure plate or the intermediate plate is connected to the outer lamella carrier for conjoint rotation therewith via a leaf spring; or
the pressure plate or the intermediate plate is connected to the counter-plate for conjoint rotation therewith via a leaf spring.

11 . The hybrid module of claim 10 wherein the pressure plate or the intermediate plate is connected to the outer lamella carrier for conjoint rotation therewith via the leaf spring.

12 . The hybrid module of claim 11 , wherein the pressure plate and the intermediate plate are both connected to the outer lamella carrier via the leaf spring.

13 . The hybrid module of claim 11 , wherein:
the outer lamella carrier comprises an outward-extending radial flange or an outward-extending tab; and the leaf spring is fixed to the outward-extending radial flange or to the outward-extending tab.

14 . The hybrid module of claim 13 , wherein:
the pressure plate or the intermediate plate comprises radially outward-extending web-type extensions; and the leaf spring is fixed to the radially outward-extending web-type extensions.

15 . The hybrid module of claim 14 , wherein:
the outer lamella carrier comprises axially extending apertures; and the intermediate plate comprises the radially outward-extending web-type extensions; and the radially outward-extending web-type extensions are engaged with the axially extending apertures.

16 . The hybrid module of claim 11 , wherein:
the outer lamella carrier comprises an internal toothing; a one of the pressure plate or the intermediate plate is connected to the outer lamella carrier via the leaf spring; and the other of the pressure plate or the intermediate plate comprises an external toothing engaged with the internal toothing in a manner which prevents relative rotation but allows axial movement.

17 . The hybrid module of claim 16 , wherein:
the intermediate plate is connected to the outer lamella carrier via the leaf spring; and the pressure plate comprises the external toothing engaged with the internal toothing.

18 . The hybrid module of claim 10 wherein the pressure plate or the intermediate plate is connected to the counter-plate for conjoint rotation therewith via the leaf spring.

19 . The hybrid module of claim 18 , wherein the pressure plate and the intermediate plate are both connected to the counter-plate via the leaf spring.

20 . The hybrid module of claim 18 , wherein:
the counter-plate comprises an outward-extending radial flange or an outward-extending tab; and the leaf spring is fixed to the outward-extending radial flange or to the outward-extending tab.

21 . The hybrid module of claim 20 , wherein:
the pressure plate or the intermediate plate comprises radially outward-extending web-type extensions; and the leaf spring is fixed to the radially outward-extending web-type extensions.

22 . The hybrid module of claim 21 , wherein:
the outer lamella carrier comprises axially extending apertures; and the intermediate plate comprises the radially outward-extending web-type extensions; and the radially outward-extending web-type extensions are engaged with the axially extending apertures.

23 . The hybrid module of claim 18 , wherein:
the outer lamella carrier comprises an internal toothing; a one of the pressure plate or the intermediate plate is connected to the outer lamella carrier via the leaf spring; and the other of the pressure plate or the intermediate plate comprises an external toothing engaged with the internal toothing in a manner which prevents relative rotation but allows axial movement.

24 . The hybrid module of claim 23 , wherein:
the intermediate plate is connected to the outer lamella carrier via the leaf spring; and the pressure plate comprises the external toothing engaged with the internal toothing.

25 . The hybrid module of claim 10 , further comprising the dual-mass flywheel, wherein the outer lamella carrier is coupled to the dual-mass flywheel by toothing engagement.

26 . The hybrid module of claim 25 , wherein:
the outer lamella carrier comprises an external toothing; the dual-mass flywheel comprises a radially inward-extending flange; the radially inward-extending flange comprises an internal toothing; and the internal toothing is engaged with the external toothing.
