The anti-side-rolling device comprises a first telescopic rod, a second telescopic rod and a pulling and pressing rod, the first telescopic rod is vertically installed on one side of a bogie and a vehicle body, and the second telescopic rod and the pulling and pressing rod are vertically installed on the other side of the bogie and the vehicle body. The two ends of the first telescopic rod are hinged to a vehicle body and a bogie respectively, one end of the second telescopic rod is hinged to the vehicle body, the other end of the second telescopic rod is hinged to one end of the swing arm, the other end of the swing arm is hinged to the bogie, one end of the pulling and pressing rod is hinged to the middle of the swing arm, and the other end of the pulling and pressing rod is hinged to the vehicle body. Inner cavities of the first telescopic rod and the second telescopic rod are communicated with a pressure medium cavity of a pressure medium cylinder through pipelines, a piston is installed in the pressure medium cylinder, the pressure medium cavity is formed in one side of the piston, and a spring is installed on the other side of the piston. A torsion bar which is difficult to install is omitted, but side rolling resistance can still be achieved, and floating and sinking movement of a vehicle body is not limited.

    本发明公开了一种抗侧滚装置,其包括第一伸缩杆、第二伸缩杆和拉压杆,所述第一伸缩杆竖直安装在转向架和车体的一侧,所述第二伸缩杆和拉压杆竖直安装在所述转向架和车体的另一侧,所述第一伸缩杆的两端分别与车体和转向架铰接,所述第二伸缩杆的一端与车体铰接,另一端与摆臂的一端铰接,所述摆臂的另一端与所述转向架铰接,所述拉压杆的一端与所述摆臂的中部铰接,所述拉压杆的另一端与所述车体铰接,且所述第一伸缩杆、第二伸缩杆的内腔分别经管路与压力介质缸的压力介质腔连通,所述压力介质缸内安装活塞,所述活塞的一侧设置为所述压力介质腔,另一侧安装弹簧。本发明取消了安装困难的扭杆,但仍能实现抗侧滚并不限制车体浮沉运动。
