The invention relates to the technical field of vehicles, and provides a motor train unit traction transmission system. Comprising an integrated power supply unit and a traction motor, the integrated power supply unit comprises a cascade rectifier unit, a direct current conversion unit and a traction inverter unit which are connected in sequence, and further comprises an auxiliary power supply unit connected to the output side of the direct current conversion unit, and the direct current conversion unit supplies power to the traction inverter unit and the auxiliary power supply unit. The traction motor is powered by the traction inverter unit. The modular thought is adopted, and traction power supply and auxiliary power supply components are integrated in one unit. The train traction transmission system is fundamentally innovated, the train power supply structure is simplified, the efficiency of the whole traction transmission link is improved, the loss of the traction transmission system is greatly reduced, the network side capacity configuration is reduced, and the train traction transmission system conforms to the development direction of high speed, light weight and low energy consumption of trains.
