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.

    本发明涉及车辆技术领域,提供一种动车组牵引传动系统。包括:集成式供电单元和牵引电机;所述集成式供电单元包括依次相连的级联整流器单元、直流变换单元和牵引逆变器单元,还包括连接在直流变换单元输出侧的辅助供电单元,所述牵引逆变器单元和所述辅助供电单元均由所述直流变换单元供电,所述牵引电机由所述牵引逆变器单元供电。本发明采用模块化思想,将牵引供电和辅助供电部件集成于一个单元内。从根本上对列车牵引传动系统进行了革新,精简了列车供电结构,而且提升整个牵引传动环节的效率,极大地减小了牵引传动系统的损耗,降低了网侧容量配置,符合列车高速化、轻量化和低能耗的发展方向。
