The invention discloses a hybrid power locomotive system for rail transit. The system comprises a piezoelectric power generation module, a pantograph power supply module, wheels and a connecting shaft; and the piezoelectric power generation module is arranged on the connecting shaft between the two wheels, voltage generated by the piezoelectric power generation module is stored through a DC/DC converter, then a direct-current power source from the piezoelectric power generation module and the pantograph power supply module is converted into a frequency-stabilized alternating-current power source through the current inverter, an alternating-current power source drives a traction motor, and the traction motor drives the wheels to rotate. Through an arranged elastic mechanism, in the vibration process of an elastic shifting piece, a piezoelectric plate makes reciprocating motion and generates charge movement, direct current is converted into alternating current through the inverter to drive the traction motor, the traction motor drives the wheels to rotate, an energy circulation system is formed, a hybrid power system is formed in cooperation with the power supply of the pantograph, and the efficiency of the hybrid power driving system is improved.

    本发明公开了一种用于轨道交通的混合动力机车系统,包括压电发电模块、受电弓供电模块、车轮、连轴;所述压电发电模块设置在两个所述车轮之间的连轴上,压电发电模块产生电压经过DC/DC转换器存储,之后经过电流逆变器将源自压电发电模块与受电弓供电模块的直流电源转化为稳频的交流电源,交流电源驱动牵引电机,牵引电机驱动车轮转动;通过设置的弹性机构在弹性拨片振动的过程中,使压电片发生往复式的运动,产生电荷移动,通过逆变器将直流电转换成交流电,驱动牵引电机,牵引电机驱动车轮转动,形成了能量循环系统,配合受电弓的供电形成混合动力系统,提高混合动力驱动系统的效率。
