The auxiliary supporting wheel mechanism comprises an oil cylinder mounting seat, a height adjusting oil cylinder, an auxiliary supporting frame and an auxiliary rotating part, the oil cylinder mounting seat is used for being connected with a main framework, the height adjusting oil cylinder is connected with the main framework through the oil cylinder mounting seat, and the auxiliary supporting frame is connected with the auxiliary rotating part through the height adjusting oil cylinder. The auxiliary supporting frame is connected with the height adjusting oil cylinder, the auxiliary supporting frame and the oil cylinder installation base form a guide rail sliding pair, the auxiliary rotating part is rotationally connected with the auxiliary supporting frame, and the height adjusting oil cylinder is used for adjusting the derailing height of the auxiliary rotating part. Under the working conditions of curve driving, large left and right side vibration and the like, intervention supporting driving of the auxiliary supporting wheels can be achieved, mechanical limiting is formed, and the situation that left and right side swing deformation is further expanded, and driving safety is affected is avoided; in addition, the derail height of the supporting wheels is adjustable, the supporting wheels can adapt to various line working conditions with different curves and different superelevation, and then the running safety of rail running of the rail-road car is effectively improved.
本发明公开了一种公铁两用车转向架的辅助支撑轮机构及转向架,包括油缸安装座、高度调节油缸、辅助支撑架和辅助转动部,所述油缸安装座用于与主构架连接,所述高度调节油缸通过油缸安装座与主构架连接,所述辅助支撑架与高度调节油缸连接,且与油缸安装座构造成导轨滑动副,所述辅助转动部与辅助支撑架转动连接,所述高度调节油缸用以调节辅助转动部的离轨高度。本发明能够在曲线行驶、左右侧振动较大等工况下,实现辅助支撑轮的介入支撑行驶,形成机械限位,避免左右侧摆动变形的进一步扩大、影响行车安全;另外,支撑轮离轨高度可调,能适应于多种不同曲线不同超高的线路工况,进而有效提高公铁两用车轨道行驶的运行安全性。
