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 high-speed train driver's cab with a windage brake device and the high-speed train. The high-speed train driver's cab includes a driver's cab body, and multiple sets of windage brake plates are installed on the variable section area of ​​the driver's cab body. The moving plates are arranged side by side along the length direction of the driver's cab body, and each group of wind resistance brake plates includes a plurality of brake unit plates arranged at intervals along the outer contour of the variable cross-section area. The unit board is installed in a misplaced position, and an opening and closing drive mechanism for retracting or opening the brake unit board is installed on the driver's cab body. The high-speed train driver's cab with the wind resistance braking device has simple structure, convenient installation and high reliability, can meet the demand for braking force of the high-speed train under the emergency braking state, and solve the problem of insufficient braking force of the high-speed train during emergency braking.

Description

technical field [0001] The invention relates to the technical field of rail transit equipment, in particular to a high-speed train driver's cab and a high-speed train with wind resistance braking devices. Background technique [0002] A high-speed train is a high-speed moving object close to the ground. When the speed of a traditional train in my country is 120km / h, the air resistance accounts for about 40% of the total resistance; Air resistance accounts for about 75% of the total resistance; when the speed is 300km / h, the 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-speed train is increased from 300km / h to 350km / h, the kinetic energy of the train i...
