Abstract
Disclosed is a drive unit () with a housing (), an electric motor () arranged in the housing with a rotor shaft (). At least two oil chambers () are arranged in the housing (). In each case the oil chambers include an oil zone () and an air zone () with an oil capture pocket (). The oil chambers are flow-connected to one another via an overflow channel (). Axial end areas of the rotor shaft () project into the oil chambers (), and the rotor shaft defines a connecting channel () which flow-connects the oil chambers () to one another. A transmission is coupled to one axial end area or the rotor shaft () and an impulse disk () is coupled to the opposite axial end area, where each axial end area conveys oil to the respective oil capture pocket ().
