The spline anti-side-rolling torsion bar device for the railway vehicle bogie comprises a torsion bar shaft, a first spline end, a second spline end, a spline movable end and a spline fixed end, the first spline end and the second spline end are arranged at the two ends of the torsion bar shaft respectively, one end of the first spline end is connected with the spline movable end, and the other end of the second spline end is connected with the spline fixed end. One end of the second spline end is connected with the spline fixing end; the torsion bar shaft is of a stepped shaft structure, and a wear-resistant coating is arranged on the outer side of the torsion bar shaft. According to the spline anti-side-rolling torsion bar device for the railway vehicle bogie, the overall structure is good in wear-resisting effect and convenient to disassemble and assemble; compared with the prior art, the spline has the advantages that the uniform connection stress effect can be achieved, meanwhile, the large contact area can be achieved when the spline is meshed, and therefore large loads can be borne, and the good connection strength is achieved; meanwhile, good installation centering performance and guidance performance are achieved, large torque can be transmitted, and use on high-speed driving equipment is facilitated.

    本发明涉及一种轨道车辆转向架用花键抗侧滚扭杆装置,包括扭杆轴、第一花键端、第二花键端、花键活动端和花键固定端,所述扭杆轴的两端分别设置有第一花键端和第二花键端,所述第一花键端的一端连接安装有花键活动端,所述第二花键端的一端连接安装有花键固定端;所述扭杆轴为阶梯轴结构,且扭杆轴的外侧设置有耐磨涂层;该轨道车辆转向架用花键抗侧滚扭杆装置,整体结构耐磨效果好,拆装方便;能够具有较为均匀的连接受力效果,同时,花键咬合时能够具有较大的接触面积,从而能够承受较大的载荷,具有良好的连接强度;同时,具有良好的安装对中性和导向性,能够传递较大的转矩,便于在高速驱动的设备上使用。
