The invention provides a driving device of a railway vehicle, a bogie and the railway vehicle. The driving device is characterized in that an output shaft of a power box is in butt joint with an input shaft of a gearbox; one end of the first connecting rod assembly is connected with the side, away from the output shaft, of the power box, and the other end of the first connecting rod assembly is connected with the framework. One end of the second connecting rod assembly is connected with one side of the power box away from the output shaft, and the other end of the first connecting rod assembly is connected with the framework; an included angle is formed between the axial extending direction of the first connecting rod assembly and the axial extending direction of the second connecting rod assembly, so that vibration borne by the power box is buffered. The two connecting rod assemblies forming the included angle are arranged to be connected with the power box and the framework correspondingly, elastic connection between the power box and the framework is achieved, vibration from the rail is buffered, the motor is protected, and the service life of the motor is prolonged.
本发明提供一种轨道车辆的驱动装置、转向架及轨道车辆,驱动装置包括:动力箱的输出轴与齿轮箱的输入轴对接;第一连杆组件的一端与动力箱远离输出轴的一侧连接,第一连杆组件的另一端与构架连接;第二连杆组件的一端与动力箱远离输出轴的一侧连接,第一连杆组件的另一端与构架连接;其中,第一连杆组件的轴向延伸方向和第二连杆组件的轴向延伸方向形成有夹角,以实现缓冲动力箱受到的振动。本发明通过设置两个形成有夹角的连杆组件分别与动力箱和构架连接,实现了动力箱与构架之间的弹性连接,有利于缓冲来自轨道的振动,保护电机,延长电机的使用寿命。
