A device for the thermal management of a power train includes a main housing accommodating an electric motor and its cooling circuit and a speed reducer including a lubrication circuit. The main housing includes an oil sump arranged in the lower part of the main housing and a partition separating same into two parts, wherein there are arranged respectively, on the one hand, the motor and its cooling circuit, and on the other hand, the speed reducer and its lubrication circuit, while an oil channel extends in the oil sump through the partition in order to bring the two parts into communication and includes one end on the speed reducer side provided with a valve for regulating the oil flow, controlled by the oil temperature, so as to close the oil passage in the oil channel when the oil temperature on the speed reducer side reaches a predetermined temperature threshold.
