Description
Technical field
The present invention relates to rolling stock, comprise the brake equipment of magnetic suspension train, electric express locomotive and EMU etc., particularly a kind of hydraulic drive aerodynamic brake device with single wing plate.
Background technology
Along with the raising of train operation speed, safety problem will more and more receive people's concern.And braking technology is as the important defence line together that ensures passenger's life security, come into one's own all the more.Especially the brake safe technology of speed per hour 350km and above high speed train has become the emphasis of countries in the world high speed train research.At present both at home and abroad on the high speed train of running velocity 300km/h, conventionally only adopt adhesion braking, but the braking force of adhesion braking depends on the adhesion factor between wheel track, and adhesion factor declines with train speed increase, this means that, when train is run at high speed, utilizable binding force has declined on the contrary.Raising along with train speed, the speed of a motor vehicle of take is increased to 350km/h as example from 300km/h, and kinetic energy increases approximately 40%, when this part momentum transfer is gone out, if purely rely on disc brake, in braking procedure, the temperature rise of brake disc, thermal stress etc. will face a severe test so.Therefore, 350km/h and above high speed train are necessary to consider to adopt non-service braking mode while being sticked with action for brake mode in emergency circumstances or high speed, to make up the defect of adhesion braking under high speed damped condition, guarantee the safe and reliable braking of high speed train.On the 350km/h of at present research and development and above high speed train, these three kinds non-researchs that are sticked with flowing mode of linear eddy current brake, electromagnetic rail brake and aerodynamic braking have been carried out.
Eddy current brake is the relative motion that utilizes excitation electromagnet and rail, produces eddy current in rail, and the magnetic field interaction that the magnetic field that eddy current produces and excitation electromagnet produce obtains and train working direction opposite effect force component.High-Speed Eddy Braking need to increase the brake equipments such as electromagnet on existing high speed train basis, has increased the weight of train, and the energy of required consumption is large, and can produce the negative effects such as electromagnetic interference and electromagnetic radiation pollution.
Electromagnetic rail brake is called again electromagnetic path braking.It is by the electromagnet on the bogie of car is adsorbed in orbit and makes vehicle slide in orbit the braking of generation.Similar with High-Speed Eddy Braking, increase the brake equipments such as electromagnet and also can increase the weight of the weight of train.Even more noteworthy: electromagnetic rail brake is to consume train momentum by producing heat with track friction, can produce abrasion to rail, and service expenditure is large.
Aerodynamic braking conducts a research from aerodynamics angle, avoided that these two kinds of High-Speed Eddy Braking and electromagnetic rail brake are non-is sticked with some problems that flowing mode comes out completely, it is that the wing plate launching with roof increases the wind area on sense of motion, utilizing atmosphere is heat energy with the relative friction of wing plate by the kinetic transformation of train, and along with the rapid flow of air falls apart in atmosphere.It has advantages of the following aspects: 1, utilize the wing plate increase air resistance that roof launches to produce braking force, size square is directly proportional to speed, the higher braking force of speed is larger, and when high speed, this brake mode has premium properties, the defect of adhesion braking while having made up high speed; 2, aerodynamic braking makes full use of this clean energy resource of wind energy, has the meaning of energy-conserving and environment-protective; 3, aerodynamic brake only needs roof wing plate installed position to change, and with eddy current brake, the change of bogie truck is compared, and aerodynamic braking is changed less to original vehicle structure, and the transformation cycle is short, design is relatively simple; 4, aerodynamic brake does not have wear part, compares with disc brake, and friction heat is very little, and the friction heat producing also can fall apart in atmosphere at any time, has the features such as reliability is high, service expenditure is low.
Summary of the invention
