Abstract (en)
[origin: WO2021109980A1] Provided is a drivetrain system for an electrified vehicle. The drivetrain system comprises an electric motor (2) comprising a rotor and a stator; a power inverter (3) configured for supplying the stator with electric energy; a reducer (4) configured for receiving torque provided by the rotor and comprising a transmission shaft; the electric motor (2), the power inverter (3) and the reducer (4) are integrated as a drivetrain assembly (1). The drivetrain system further comprises: a cooling circuit (5) configured for being flowed through with coolant and distributing the coolant throughout the drivetrain assembly (1); the cooling circuit (5) comprising a cooling channel (33) arranged inside the power inverter (3), the cooling channel (33) comprising a coolant retaining section (35) for retaining the coolant from the cooling circuit (5), an inlet (31) for receiving the coolant and an outlet (32) for discharging the coolant. Also provided is a method of cooling the drivetrain system for an electrified vehicle.
