Abstract

This application provides a powertrain, a mounting apparatus thereof, and an electric vehicle. A housing of the powertrain is configured to accommodate rotors and stators of two drive motors. The housing includes a middle partition plate, the middle partition plate includes two bearing containers and two grooves, openings of the two bearing containers face away from each other along an axial direction of the drive motor, and each bearing container is configured to rotatably connect to a motor shaft of one drive motor. The two grooves are respectively distributed at bottoms of the two bearing containers, openings of the grooves face away from each other along the axial direction of the drive motor, a bottom of each groove includes an oil outlet hole, and the oil outlet holes of the two grooves are configured to respectively deliver oil transmitted by an internal flow channel of the middle partition plate to the motor shafts that are rotatably connected to the two bearing containers. In this solution, in a powertrain assembly process, a mandrel may be inserted into the groove used to form the oil outlet hole, to prevent the rotor from being misaligned by a magnetic force of the stator during mounting, and simplify an assembly apparatus and an assembly process.
