The invention provides a rail transit passenger and freight dual-purpose electric vehicle. The rail transit passenger and freight dual-purpose electric vehicle comprises a vehicle body, a stator and a rotor; the stator is arranged at the lower end of the vehicle body and can be electrified to generate electromagnetic force; and the rotor is located at the bottom of the vehicle body and spaced from the vehicle body, and the rotor can rotate relative to the stator under the action of electromagnetic force. The rail transit passenger and freight dual-purpose electric vehicle has the beneficial effects that an axle and a bogie in the prior art are canceled, a magnetic driving form of the stator and the rotor is adopted, and the rotor only bears positive pressure and is not affected by bending moment during working, so that fatigue damage caused by alternating stress is avoided, and the purpose of prolonging the service life of the stator and the rotor is achieved.
本发明提供了一种轨道交通客货两用电动车辆,包括:车体;定子,设置在车体的下端处,定子能够通电以产生电磁力;转子,位于车体的底部并与车体间隔设置,转子能够在电磁力的作用下相对于定子转动。本发明的有益效果是,本发明实施例取消了现有技术中的车轴和转向架,采用定子与转子的磁力驱动形式,转子工作时只承受正压力而不受弯矩作用,从而避免产生交变应力而导致的疲劳损坏,达到提高定子和转子使用寿命的目的。
