The invention relates to the technical field of railway vehicles, in particular to a guide wheel protective cover for a railway vehicle, which comprises an upper protective cover and a lower protective cover which are connected with a bogie frame, and the upper protective cover is rotatably connected with the bogie frame through a connecting assembly and can be opened and closed up and down; the upper protective cover comprises a side drainage table and a top drainage table, and the side drainage table and the top drainage table are arranged in a downward inclined mode towards the two sides of the guide wheel correspondingly. The lower protective cover is located below the top drainage table and obliquely extends towards the outer side of the guide wheel towards the side away from the side drainage table. Accumulated water on the side drainage table flows downwards to the outer side of the guide wheel, and accumulated water on the top drainage table flows downwards to the lower protective cover firstly and then flows into the outer side of the guide wheel from the side, away from the side drainage table, of the lower protective cover. The protective cover can prevent the guide wheel and the bogie frame from being corroded and damaged, the use performance of the guide wheel and the bogie frame can be improved, and the service life of the guide wheel and the bogie frame can be prolonged.

    本发明涉及轨道车辆技术领域,尤其提供了一种用于轨道车辆的导向轮防护罩,包括与转向架构架连接的上防护罩和下防护罩,上防护罩通过连接组件与转向架构架转动连接且可上下开合;上防护罩包括侧部排水台和顶部排水台,侧部排水台和顶部排水台分别朝向导向轮的两侧向下倾斜设置;下防护罩位于顶部排水台下方且朝向远离侧部排水台的一侧向导向轮外侧倾斜延伸设置;侧部排水台上的积水向下汇入导向轮外侧,顶部排水台上的积水先向下汇入下防护罩上,再经下防护罩从远离侧部排水台的一侧汇入导向轮外侧。本发明中的防护罩可防止导向轮及转向架构架腐蚀损坏,可提高导向轮及转向架构架的使用性能和使用寿命。
