The invention provides a gearbox and a driving system for a railway vehicle and the railway vehicle, and belongs to the technical field of railway vehicles. The disclosed gearbox for the railway vehicle comprises a box body, an input shaft assembly arranged corresponding to a traction motor, an output shaft assembly arranged corresponding to an axle of the railway vehicle, and an intermediate shaft assembly arranged between the input shaft assembly and the output shaft assembly. The input shaft assembly is provided with a driving gear shaft, the output shaft assembly is provided with a drivengear shaft, and the driving gear shaft and the driven gear shaft are basically arranged in parallel in the transverse direction. The intermediate shaft assembly comprises an intermediate shaft and anidle gear rotationally arranged on the intermediate shaft. Gear meshing transmission is formed between the driving gear shaft and the idle gear, and gear meshing transmission is formed between the idle gear and the driven gear shaft, so that torque output by the traction motor is transmitted to the axle. The gearbox is compact in structure and small in required installation space.
本发明提供一种轨道车辆用齿轮箱和驱动系统、以及轨道车辆,属于轨道车辆技术领域。本发明公开的轨道车辆用齿轮箱包括箱体、对应牵引电机设置的输入轴组件、对应轨道车辆的车轴设置的输出轴组件、和设置在输入轴组件和输出轴组件之间的中间轴组件;输入轴组件设置有主动齿轮轴,输出轴组件设置有与从动齿轮轴,主动齿轮轴和从动齿轮轴在横向方向上基本平行地布置;其中,中间轴组件包括中间轴以及可转动地设置在中间轴上的介轮;主动齿轮轴和介轮之间、介轮和从动齿轮轴之间分别形成齿轮啮合传动,以至于将牵引电机输出的转矩传递给车轴。本发明的齿轮箱结构紧凑、要求的安装空间小。
