Abstract: Disclosed is a drive unit (10) with a housing (12), an electric motor (14) arranged in the housing with a rotor shaft (26). At least two oil chambers (30) are arranged in the housing (12). In each case the oil chambers include an oil zone (38) and an air zone (40) with an oil capture pocket (46). The oil chambers are flow-connected to one another via an overflow channel (42). Axial end areas of the rotor shaft (26) project into the oil chambers (30), and the rotor shaft defines a connecting channel (34) which flow-connects the oil chambers (30) to one another. A transmission is coupled to one axial end area or the rotor shaft (26) and an impulse disk (32) is coupled to the opposite axial end area, where each axial end area conveys oil to the respective oil capture pocket (46).

Abstract: The invention relates to a drive unit (1) with a housing (2), an electric motor (3) arranged therein, a transmission (8) coupled to the electric motor (3), at least two oil chambers (15, 16) arranged in the housing (2), which have oil zones (20, 21) and air zones (22, 23) and in which the oil zones (20, 21) are flow-connected to one another by an overflow channel (18). A pump (14) is flow-connected on its suction side with an oil zone (20) and passes oil through the oil chambers (15, 16). A pressure-equalization channel (30) opens into the air zones (22, 23) and flow-connects them to one another.

Abstract: The present disclosure relates to a drive unit (1) with a housing (2) and an electric motor (3) arranged therein. A transmission (8) is coupled to the electric motor (3). At least one oil chamber (15) is arranged in the housing (2), the oil chamber(s) having an oil zone (21) and an air zone (22), where the air zone (22) is flow-connected by way of an inlet opening (36) to a venting channel (35) that leads to a vent (32) such that the inlet opening (36) is arranged in a central area (40) of the housing (2) of the drive unit (1).

Abstract: Disclosed is a drive unit (1) comprising a housing (2), an electric motor (3) disposed inside the housing, and at least one oil chamber (15) which is disposed in the housing (2). The oil chamber (15) comprises an oil region (21) and an air region (22) and is closed off to the outside by a housing cover (35). The housing cover (35) comprises at least one vent opening (36, 37) for venting the oil chamber (15), which is disposed at a distance from a radial outer region of the housing cover (35) and is fluidically connected to an element (32, 38, 47, 48) for venting the oil chamber (15).
