Abstract

A drive apparatus for a hybrid vehicle has an internal combustion engine, which has a crankshaft for outputting a drive power, and a torsional vibration reduction device, which is designed to reduce torsional vibrations and to transfer drive power from the crankshaft in the direction of a drivable wheel of the motor vehicle. A clutch device has a clutch input side, a clutch output side, a form-fit clutch and a frictional clutch. The torque transfer from the clutch input side to the clutch output side and thus from the crankshaft to the drivable wheel can be selectively produced, wherein the torque transition from the clutch input side to the clutch output side is enabled as soon as at least one of the two clutches is closed. The torsional vibration reduction device is arranged after the clutch device, relative to the torque transmission from the crankshaft in the direction of the drivable wheel. The clutch input side is connected to the crankshaft for conjoint rotation and the clutch output side is connected to the torsional vibration reduction device for conjoint rotation.
