Abstract:
A drive module for a vehicle has a transmission (12) and an electric machine (11) that is coupled to an input shaft (16) of the transmission (12). An air-filled cavity (23) is formed between the electric machine (11) and the transmission (12). The electric machine (11) is an external-rotor motor with a rotor (24) that surrounds the stator (25). A fan impeller (31) rotates with the rotor (24) and draws air out of the air-filled cavity (23) in an axial direction, draws the air through windings (27) of the stator (25) for cooling, and subsequently conveys the air in the radial direction into a housing-side flow duct (34) in which heated air can be accumulated and via which the air can be returned toward the cavity (23). The heated air can be cooled in the region of the flow duct (34) and/or in the region of the cavity (23).
