Problems solved by technology

[0004] However, air braking has a certain impact on the periphery of the line. After all, the kinetic energy generated by a big guy with hundreds of tons at a speed of hundreds of kilometers per hour is released in the air, which will generate strong wind pressure and noise, which will affect the personnel and facilities around the line. potential threat

Abstract

The invention relates to a vehicle, in particular to an additional braking device for a high-speed train. Connected, when multiple additional cars are located in the middle of the train, the front and last additional cars are connected to the high-speed train's moving car or trailer car; the front end of each additional car is open and the rear end is closed, and the front end of the frontmost additional car is hinged. Door; When driving, the door is closed and the front end of the additional car behind is closed by nesting the rear end of the additional car in front to reduce wind resistance; when braking, the door is open and the front end of the additional car in the rear is away from the front. The rear end of the car is attached to open its front end for ride braking. Compared with the prior art, the present invention is a safe and efficient deceleration and braking device.

Description

technical field [0001] The invention relates to a vehicle, in particular to an additional braking device for a high-speed train. Background technique [0002] At present, the speed of high-speed trains, bullet trains and subways is getting faster and faster, 250 kilometers, 350 kilometers, 450 kilometers, etc., and higher speeds are in the design. The higher the speed, the higher the requirements for braking. Every time the train arrives at a station, it is bound to slow down, which brings many problems. Early deceleration will affect the average speed of the train, delaying the arrival time at the station, and eventually the train scheduling cycle will be lengthened and the efficiency of the high-speed rail will be reduced; if the deceleration is late, the braking power will increase, and the wear of wheels and rails will increase. Large, the safety and stability of the train will deteriorate, the noise of the carriage will increase, and even the life of the train will be...
