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.

A clutch includes a drive disc, a driven disc, and a friction plate unit capable of engaging or disengaging the drive disc with or from the driven disc, the friction plate unit including a first friction plate assembly and a second friction plate assembly, the clutch further including a pressing unit configured to engage or disengage the drive disc with or from the driven disc selectively by the first friction plate assembly alone or by a combination of the first friction plate assembly and the second friction plate assembly. Such an arrangement enables the clutch to select an appropriate number of friction plates as required for engagement, solving the problem that in existing multi-plate clutches, it is impossible to select an appropriate number of friction plates to participate in work to make the clutches obtain optimal performance according to different working conditions of the automobile.

A clutch assembly includes a clutch hub, a clutch drum disposed about the clutch hub, a first gear connected to the clutch drum, the first gear configured to be coupled with a first shaft, the clutch hub configured to be coupled with a second shaft, a clutch pack disposed between the clutch hub and the clutch drum, and an air-actuated piston assembly for selective actuation of the clutch pack to connect or disconnect two drive axles in a tandem axle assembly. The clutch assembly includes a plurality of lever arms disposed between the piston assembly and the clutch pack. Each lever arm extending to engage the piston and the clutch pack. Each lever arm may be pivotally mounted to a lever carrier plate or to a fixed portion of the piston housing.
