[0005] Due to the wrinkled structure of the deflector in this scheme, the lower surface of the deflector (that is, the surface through which the airflow passes) still has wrinkles even in the stretched state, and cannot be fully stretched, which affects the flow of airflow to a certain extent. Increase driving resistance, and snow is easy to accumulate at the folds, which is not conducive to complete shrinkage and closing
At the same time, the deflectors away from the direction of train travel are in a state of complete contraction and close, and are close to the end plates. At this time, the gap between the bogie and the end plates is in a fully open state, and there is a risk of snow entering the top of the bogie. possible
In addition, for rail vehicles without front and rear end plate structures, the deflector cannot completely close the gap between the deflector and the bogie, and cannot prevent snow from entering the bogie area

Embodiment 1
[0034] Such as Figure 1 to Figure 3 As shown, the present invention provides a bogie anti-snow diversion device, which is installed in the bogie 3 area of the rail vehicle. In this embodiment, the entire flow diversion device is directly installed on the car body chassis 1 . A set of deflectors 2 are respectively installed at the front and rear ends of the bogie 3. The two sets of deflectors 2 have the same structure and are installed symmetrically with the central axis of the bogie. The two sets of deflectors 2 determine the action sequence according to the running direction of the vehicle. , which can play the role of diversion and snow prevention when rail vehicles run in both directions. The cooperative relationship between the front and rear two sets of deflectors 2 is that when the vehicle is moving forward, the deflector 2 located at the front end of the running direction stretches toward the rail surface and is in an extended and open state, and at the same time, th...
Embodiment 2
[0054] A rail vehicle, comprising a plurality of carriages, two groups of bogies 3 are installed under each carriage, and the car body chassis 1 at the front and rear ends of each group of bogies 3 are equipped with bogie deflector.

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.
Description
technical field [0001] The invention relates to a bogie anti-snow guide device and a rail vehicle, belonging to the technical field of rail vehicle manufacturing. Background technique [0002] When urban rail transit trains run in heavy snow weather in alpine regions, the snow on the line will roll up due to the influence of the turbulence in the bogie area and accumulate on the bogie. Under the action of disc brakes, etc., it will melt into water and then freeze into ice. After the reciprocating action, large ice cubes will form on the bogie at last. The ice cubes will change the dynamic characteristics of the bogie and deteriorate the performance of urban rail vehicles. The ability to pass through curves reduces the working stability of the braking system of urban rail vehicles, which seriously threatens the running stability, safety and comfort of urban rail transit trains. [0003] In the patent No. 201510973920.6, a snow prevention device for the train bogie area is pr...
