Drive assembly with an internal combustion engine and an electric machine

The invention relates to a drive assembly comprising an internal combustion engine (1), a transmission (3) with a first clutch (K1-coupling) and therebetween an electric machine (2) and a further clutch (K0 clutch) (4). Here, the K0 clutch (4) optionally, allows coupling or uncoupling of the electric machine (2). The engaging and disengaging the clutch K0 (4) by means of a hydraulic actuator (7), said transmission (3) for actuation of the transmission operations including a hydraulic system. In order to provide an improved actuator for the K0 clutch, to the adjusting means which acts on the hydraulic actuator (7) for the K0 clutch (4) is a hydraulic medium (11) derived from the transmission hydraulic system.
