The invention discloses a driving device, a bogie and a locomotive. The device comprises a traction motor, a speed reducing mechanism, a flexible plate coupler, a drum-shaped gear and an axle, whereinan output shaft of the traction motor is connected with a power input end of the speed reducing mechanism; the power output end of the speed reducing mechanism is of a hollow structure penetrating through the speed reducing mechanism, the axle sequentially penetrates through the flexible plate coupler and the power output end of the speed reducing mechanism, the power input end of the flexible plate coupler is connected with the power output end of the speed reducing mechanism, and the power output end of the flexible plate coupler transmits torque to the axle only through the drum-shaped gear. In the process, the flexible plate coupler and the drum-shaped gear are matched to compensate axial, radial and angular displacement between the output shaft of the traction motor and the axle, sothat the mounting requirement of the suspension of the traction motor can be met. The coupling is matched with the drum-shaped gear, so that the radial space of the whole driving device, especially two ends of the axle, can be saved.
本发明公开了一种驱动装置、转向架和机车,包括牵引电机、减速机构、挠性板联轴器、鼓形齿轮和车轴,其中,牵引电机的输出轴与减速机构的动力输入端相连,减速机构的动力输出端为贯穿减速机构的空心结构,车轴依次穿过挠性板联轴器和减速机构的动力输出端,挠性板联轴器的动力输入端与减速机构的动力输出端连接,且挠性板联轴器的动力输出端仅通过鼓形齿轮向车轴传递力矩。在上述过程中挠性板联轴器以及鼓形齿轮的配合能够补偿牵引电机输出轴与车轴之间的轴向、径向和角位移从而能够满足牵引电机架悬的安装要求。联轴器和鼓形齿轮的配合能够节省整个驱动装置特别是车轴两端的径向空间。
