Abstract

This application provides a powertrain and an electric vehicle. A motor housing of the powertrain is configured to: fasten a stator of a drive motor and accommodate a rotor and a motor shaft that are of the drive motor. The rotor is fastened to the motor shaft. A reducer housing of the powertrain is configured to enclose an opening of the motor housing. An inner cavity of the reducer housing is configured to accommodate one planetary gear set of a planetary reducer. The reducer housing includes a through hole. The through hole is configured to connect the inner cavity of the reducer housing and an inner cavity of the motor housing. One end of the motor shaft extends into the inner cavity of the reducer housing from the through hole in an axial direction of the powertrain. The one end of the motor shaft is configured to serve as a sun gear of the one planetary gear set. In this way, the rotor of the drive motor can directly transmit power to a planet gear of the one planetary gear set of the planetary reducer through the one end of the motor shaft, so that a transmission process between the drive motor and the planetary reducer is more stable, and a bending resistance capability of the motor shaft is further improved. This increases a critical rotation speed of the rotor of the drive motor.
