The invention provides a traction transmission system for a railway vehicle and the railway vehicle. The traction transmission system comprises a transmission gear box which comprises a driving gear shaft assembly and a driven gear shaft assembly which are meshed with each other; and a coupler assembly which is arranged at the two sides of the transmission gear box by penetrating through the driving gear shaft assembly in the axis direction of the driving gear shaft assembly, and transmits torque to the driving gear shaft assembly. According to the traction transmission system and the railway vehicle, the coupler assembly and the transmission gear box are matched to share a part of axial space, and coupling parts are adaptively arranged at the two sides of the transmission gear box, so that a small amount of axial space between the transmission gear box and the bogie is used more sufficiently; and therefore, the axial space configured by parts is effectively reduced, and further the axial space for a high-speed bogie with a built-in axle box body and a large-size traction motor is saved, transmission is stable, and the operation is reliable.

    本申请提供一种用于轨道车辆的牵引传动系统及轨道车辆。该牵引传动系统包括:传动齿轮箱,其包括相互啮合的主动齿轮轴组件与从动齿轮轴组件;联轴器组件,其沿所述主动齿轮轴组件的轴线方向穿过所述主动齿轮轴组件设置在所述传动齿轮箱的两侧,并将转矩传递至所述主动齿轮轴组件。根据本申请的牵引传动系统及轨道车辆,通过联轴器组件与传动齿轮箱的配合,使得二者实现了一部分轴向空间的共享,且将联轴器部件适配性地布置于传动齿轮箱的两侧,提高了对传动齿轮箱于转向架之间的少量轴向空间的充分利用,从而有效压缩零部件配置的轴向空间,以便节省出用于内置轴箱体高速转向架与大尺寸牵引电机的轴向空间,传动平稳、运行可靠。
