Abstract

A hybrid module for a drivetrain of a motor vehicle includes a separating clutch for coupling an input-side drive shaft with an output-side intermediate shaft, and an actuating device for actuating the separating clutch, co-rotatable with the drive shaft or with the intermediate shaft. The actuating device includes a pressure chamber connectable to a pressure source arranged to provide a hydraulic actuating pressure through a hydraulic medium, and a compensation device for at least partially compensating a change in pressure in the pressure chamber from a first centrifugal force acting on the hydraulic medium. The drive shaft may be a crankshaft of an internal combustion engine arranged for mechanically driving the motor vehicle and the intermediate shaft may be a rotor shaft for an electric machine arranged for electrically driving the motor vehicle.
