The invention discloses a railway vehicle spoiler device, and relates to the technical field of railway vehicles, the railway vehicle spoiler device comprises a pair of spoilers used for being mounted on the outer surface of a tail vehicle head, the spoilers are symmetrically arranged about a symmetry axis, and the symmetry axis is in the extending direction of the tail vehicle head; the spoilers are perpendicular to the surface of the shell of the tripper head where the spoilers are located; in the length direction of the spoiler, the spoiler inclines in the direction away from the symmetry axis from the end close to the opening and closing cover to the end close to the front window of the cab. When the railway vehicle spoiler device provided by the embodiment of the invention is used, the spoiler has a certain blocking effect on airflow, so that the flow speed of the airflow is reduced, the area of a positive pressure area at the head of a tripper car is increased, the aerodynamic resistance during train operation can be effectively improved, the upward lift force of the tripper car can be reduced, the train operation energy consumption is reduced, and the service life of the train is prolonged. Meanwhile, the tripper car wheel-rail friction force is increased, and the stability and safety of the tripper car during high-speed running of the train are improved.

    本发明公开了轨道车辆扰流装置,涉及轨道车辆技术领域,轨道车辆扰流装置包括一对用于安装于尾车车头的外表面的扰流板,一对扰流板关于对称轴对称设置,对称轴沿尾车车头的延伸方向;扰流板垂直于其所在位置的尾车车头的外壳表面;沿扰流板的长度方向,由靠近开闭罩的一端至靠近司机室前窗的一端,扰流板向远离对称轴的方向倾斜。使用本具体实施例提供的轨道车辆扰流装置时,扰流板对气流具有一定的阻挡作用,会使气流的流速降低,增大尾车车头处的正压区域的面积,可以有效改善列车运行时的气动阻力及减小尾车向上的升力,从而减小列车运行能耗,同时增大尾车轮轨摩擦力,增加列车高速运行时的尾车稳定性和安全性。
