  "textContent": "This application provides an oil-cooled powertrain and an electric vehicle. The oil-cooled powertrain includes a reducer, a motor, and an oil through pipe. The reducer includes a reducer input shaft. The motor includes a motor shaft. The reducer input shaft is fastened to the motor shaft, and the motor shaft is configured to transmit power to the reducer input shaft. The reducer input shaft includes a reducer shaft cavity. The reducer shaft cavity is configured to accommodate the oil through pipe and a part of the motor shaft. The oil through pipe and the reducer input shaft are oppositely fastened. The motor shaft includes a motor shaft cavity. The oil through pipe is configured to convey cooling oil to the motor shaft cavity. In an axial direction of the motor, the reducer shaft cavity penetrates the reducer input shaft, and the motor shaft cavity penetrates the motor shaft.",
