Railway vehicle power generation device

The invention discloses a railway vehicle power generation device. The railway vehicle power generation device comprises a power generation part used for outputting alternating current, a drive part used for converting vertical vibration of a railway vehicle into power, for cutting magnetic induction lines, of a rotor unit of the power generation part, a rectification part used for rectifying thealternating current into direct current, and an energy storage part used for storing the direct current. According to the railway vehicle power generation device, vibration generated by irregularity of a track in the driving process of the railway vehicle is sufficiently utilized, the vertical vibration of the railway vehicle is converted into the electric energy and stored, and the stored electric energy can serve as power supplementation of the railway vehicle. The railway vehicle device is simple in structure and relatively low in cost. 本发明公开了种轨道车辆发电装置，包括用以输出交流电的发电部，用以提供轨道车辆的垂向振动转换为发电部的动子单元切割磁感线的动力的驱动部，用以对交流电整流成直流电
