Problems solved by technology
[0004] The current two-way wind resistance braking device has a relatively complex structure, and the problem that the wind resistance area cannot be effectively used during two-way braking
At the same time, the opening and closing of the wind resistance braking device is completely dependent on the driving device, which requires a large driving force and can only be driven by hydraulic pressure, resulting in a slow opening and closing speed

The invention discloses a bi-directional wind resistance braking device for a high-speed train, belonging to the wind resistance braking field. The high-speed train bi-directional wind resistance braking device comprises a wind resistance plate which can be used for braking, a base of each component which can be installed and an opening / closing part which completes the opening / closing of the windresistance braking device; the opening / closing portion includes a first opening / closing portion and a second opening / closing portion symmetrically disposed, and each of the first opening / closing portion and the second opening / closing portion includes a cylinder for providing a driving force and an opening / closing unit for opening / closing an air resistance plate. The first opening and closing portion and the second opening and closing means are similar in structure and function to the first opening and closing means, but are symmetrical in mounting position to the first opening and closing means and open and brake in the opposite direction to the first opening and closing means. The invention realizes the bi-directional wind resistance braking of the high-speed train by applying the wind resistance braking field of the high-speed train, and has the characteristics of simple structure, small driving force required and quick opening and closing.
Description
Technical field [0001] The invention belongs to the field of braking devices, and particularly relates to the field of bidirectional wind resistance braking devices applied to high-speed trains. Background technique [0002] When a high-speed train is braking, the wind blocking plate is opened from the surface of the streamlined train to the outside, and the wind blocking plate will bear air resistance, forming a braking force that can directly decelerate the train. The aerodynamic resistance is proportional to the square of the speed. The higher the speed, the greater the braking force. Therefore, the wind resistance braking method has excellent characteristics during high-speed braking. [0003] Chinese invention patent CN106882169A provides a two-way braking device for train wind resistance. It designs a braking unit with two braking units. The two braking units complete simultaneous reverse opening and closing under the action of the hydraulic drive device through the engagemen...
