The invention discloses an automobile transmission system configuration for a pure electric vehicle. The automobile transmission system configuration comprises a first power source, a second power source, a transmission gear set and a differential assembly, the first power source, the second power source and the transmission gear set are all constructed with a transmission inner shell as a carrier, in the first power source, an EM1 motor is connected with a PGS planet row gear ring through a motor shaft, and in the second power source, a PGS planet row gear ring is connected with a PGS planet row gear ring through a motor shaft; one end of the brake is connected with the PGS planet row sun gear, the other end of the brake is connected with the transmission inner shell, one end of the clutch is connected with a PGS planet row gear ring, and the other end of the clutch is connected with the PGS planet row sun gear. In the second power source, the EM2 motor directly transmits power to the differential assembly on the wheels of the vehicle through the transmission gear set so that the purpose that the EM2 motor directly drives the vehicle can be achieved, various different working modes can be generated through combined use of the power sources and the gear shifting elements, and the motor torque requirement and the manufacturing cost are reduced.
