    摘要: A snow-accumulation-preventing and flow guide device for a bogie, and a rail vehicle. The snow-accumulation-preventing and flow guide device for a bogie includes a driving mechanism, and a first flow guide plate (5), a second flow guide plate (6) and a third flow guide plate (7) which are sequentially connected in a length direction of a vehicle body; two sides of the first flow guide plate (5), of the second flow guide plate (6) and of the third flow guide plate (7) are connected by means of extending-retracting portions (8), a top sealing plate (21) is mounted on tops of the first flow guide plate (5) and the third flow guide plate (7), the first flow guide plate (5), the second flow guide plate (6), the third flow guide plate (7), the extending-retracting portions (8) at two sides and the top sealing plate (21) together enclose a sealed cavity (9), top ends of the first flow guide plate (5) and the third flow guide plate (7) are configured to be rotatable around fixed points, the fixed points are provided on the top sealing plate (21) or the vehicle body, a bottom end of the first flow guide plate (5) is rotatably connected to the second flow guide plate (6), the second flow guide plate (6) and the third flow guide plate (7) can be connected to each other in a telescopic and slidable manner, and the driving mechanism drives the flow guide plates (5, 6, 7) to extend and open in a rail direction or retract and close in a direction of the vehicle body.

    摘要: The present disclosure relates to a suspension traction device of a low floor articulated rail vehicle, which comprises swing bolster mechanisms, traction rod mechanisms, primary springs and secondary springs. Two swing bolster mechanisms and two traction rod mechanisms are provided, two swing bolster mechanisms are provided respectively in the middle of two groups of wheel-sets. Each swing bolster mechanism is connected to the frame by a set of traction rod mechanisms and is connected to the vehicle body by means of a rotary mechanism. The disclosure has the advantages of simple and compact structure and light weight. It not only realizes the transmission of the traction and the braking force when the vehicle is running, carries the vertical, horizontal and vertical load, which greatly improves the small curving performance of the vehicle, but also reduces the height of the floor surface and the driving performance of the vehicle has also been greatly improved.
