The present disclosure relates to a drivetrain system for an electrified vehicle. The drivetrain system comprises an electric motor configured for providing with drive power and comprising a rotor and a driveshaft driven by the rotor; a speed reducer configured for speed-reducing and increasing torque received from the driveshaft, the speed reducer comprising an intermediate transmission shaft with a hollow axial passage; and a pumping component configured for transferring lubricant. The pumping component is mechanically integrated on and driven by the intermediate transmission shaft, and comprises a plurality of passages for supplying lubricant into the hollow axial passage of the intermediate transmission shaft and to the components dispositioned onto the intermediate transmission shaft.
