The invention relates to a bogie snow-accumulation-preventing flow guide device and a railway vehicle. The device comprises a driving mechanism, and a first flow guide plate, a second flow guide plateand a third flow guide plate which are sequentially connected in the length direction of a vehicle body. The two sides of the first flow guide plate, the two sides of the second flow guide plate andthe two sides of the third flow guide plate are connected through telescopic parts. The first flow guide plate, the second flow guide plate, the third flow guide plate and the telescopic parts on thetwo sides jointly define a cavity with an opening in the upper portion. The top ends of the first flow guide plate and the third flow guide plate are rotationally connected with the vehicle body; thebottom end of the first flow guide plate is rotationally connected with the second flow guide plate, the second flow guide plate and the third flow guide plate can be in relative telescopic sliding connection, and the driving mechanism drives the first flow guide plate to rotate in the rail direction to achieve stretching and unfolding or rotate in the vehicle body direction to achieve contractionand folding. Through the design of the telescopic flow guide plates, the flow guide and snow accumulation prevention effects of the bogie are greatly improved.

    本发明涉及一种转向架防积雪导流装置及轨道车辆,包括驱动机构及沿车体长度方向依次连接的第一导流板、第二导流板和第三导流板:所述第一导流板、第二导流板及第三导流板的两侧分别通过伸缩部连接,所述的第一导流板、第二导流板、第三导流板及两侧的伸缩部共同围成上部敞口的腔体,所述第一导流板和第三导流板的顶端与车体转动连接,所述第一导流板的底端与第二导流板转动连接,所述第二导流板与第三导流板可相对伸缩滑动连接,所述驱动机构带动第一导流板向轨道方向旋转实现伸展打开或向车体方向旋转实现收缩合拢。本发明通过可伸缩导流板的设计,大幅提升了转向架的导流和防积雪效果。
