The invention relates to the technical field of rail traffic, in particular to a torsion bar device based on a rail vehicle bogie, which comprises a torsion bar, a spline is arranged on one side of the torsion bar, a torsion arm is fixedly connected to the outer wall of the spline, a small arm is rotatably connected to one end of the torsion arm, a supporting rod is movably mounted at the other end of the torsion arm, and supporting spherical hinges are arranged at two ends of the supporting rod. A supporting assembly is fixedly installed on the outer wall of the inner side of the torsion rod, an upper installation base is arranged at one end of the supporting rod, an oil supply head is arranged on the inner side of the upper installation base, an oil box is fixedly connected to the bottom of the oil supply head, a damping rod is arranged between the small arm and the supporting rod, and a telescopic oil rod is fixedly installed at one end of the oil box. The oil box is filled with standby lubricating oil, the oil supply head is connected to the oil nozzle of each rotating part through the oil pipe, and during maintenance, the telescopic oil cylinder extends to push the plunger in the oil box, so that the lubricating oil is squeezed into the rotating parts through the oil pipe, and the rotating parts are conveniently maintained and lubricated.

    本发明涉及轨道交通技术领域,具体为一种基于轨道车辆转向架的扭杆装置,包括扭杆,扭杆一侧设置有花键,花键外壁固定连接有扭力臂,扭力臂一端转动连接有小臂,扭力臂另一端活动安装有支撑杆,支撑杆两端均设置有支撑球铰,扭杆内侧外壁固定安装有支撑组件,支撑杆一端设置有上安装座,上安装座内侧设置有供油头,供油头底部固定连接有油盒,小臂与支撑杆之间设置有阻尼杆,油盒一端固定安装油伸缩油杆;本发明在油盒内部转满备用润滑油,供油头通过油管连接至各个转动部件的油嘴口,在保养维护时时,通过伸缩油缸伸长,推动油盒内部的柱塞,使得润滑油通过油管挤入转动部件内部,方便对转动部件进行维护润滑。
