a housing;
an electric motor arranged in the housing, the electric motor having a rotor shaft with a first end portion and a second end portion opposite the first end portion;
first and second oil chambers arranged in the housing, each of the first and second oil chambers comprising an oil zone and an air zone with an oil capture pocket; and
an overflow channel flow-connecting the oil zone of the first and second oil chambers;
wherein the first end portion projects into the first oil chamber, the second end portion projects into the second oil chamber, and the rotor shaft defines a connecting channel that flow-connects the first and second oil chambers;
wherein a transmission is coupled to the first end portion of the rotor shaft and an impulse disk is coupled to the second end portion of the rotor shaft; and
wherein the transmission and the impulse disk are configured to deliver oil from the respective oil zone to the corresponding oil capture pocket of the first and second oil chambers, and each oil capture pocket is flow-connected by an inlet channel to an oil inlet that opens into the connecting channel, so that oil can flow from each oil capture pocket via the inlet channels into the connecting channel.
