Problems solved by technology

Traditional train braking methods rely on tread braking, disc braking or regenerative braking depending on the adhesion between the wheels and rails. As the speed of high-speed trains increases, the braking distance will be greatly extended when the train is braking at a speed of 350km / h. The train cannot stop within the traditional braking distance of 350km / h.
[0004] Traditional braking forms can no longer meet the braking needs of high-speed trains under emergency conditions such as earthquakes or train collisions

Abstract

The invention discloses a double-layer wind resistance brake device, a double-layer cab structure and a high-speed train. The double-layer wind resistance brake device includes an outer layer wind resistance brake plate and an inner layer wind resistance brake plate installed in the variable section area of ​​the train. The outer windage braking plate includes a plurality of outer braking unit plates arranged laterally along the outer contour of the variable cross-section area, and the inner layer wind resistance braking plate includes a plurality of inner layer braking unit plates arranged laterally along the outer contour of the variable cross-section area, The opening and closing drive mechanism is installed on the driver's cab of the high-speed train. When the outer layer wind resistance brake plate and the inner layer wind resistance brake plate are opened, the inner layer brake unit plate is located inside the outer layer brake unit plate and is located on the adjacent outer layer brake unit plate. In the gap between the unit boards. The double-layer windage braking device, the double-layer driver's cab structure and the high-speed train have simple structure, convenient installation, and high reliability, which can meet the demand for braking force of the high-speed train under emergency braking and solve the problem of high-speed train braking during emergency braking. The problem of lack of motivation.

Description

technical field [0001] The invention relates to the technical field of rail transit equipment, in particular to a double-layer wind resistance braking device, a double-layer driver's cab structure and a high-speed train. Background technique [0002] When the speed of traditional trains in my country is 120km / h, the air resistance accounts for about 40% of the total resistance; for the speed-up train composed of blunt locomotives pulling speed-up passenger cars (the bottom of the vehicle is exposed), when the speed is 160km / h, the air resistance accounts for about 75% of the total resistance; At 300km / h, air resistance accounts for about 85% of the total resistance. The air resistance of the train is proportional to the square of the train speed. With the increase of the train speed, the air resistance of the train increases rapidly, and the proportion of the air resistance of the train in the total resistance is also increasing. [0003] When the running speed of the high-s...
