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 single-blade plate hydraulic drive type aerodynamic brake.
Background technology
Along with the raising of train operation speed, safety problem will more and more receive people's attention.And braking technology comes into one's own all the more as the important defence line together that ensures passenger's life security.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; Usually only adopt adhesion braking; But the braking force of adhesion braking depends on the adhesion factor between wheel track; And adhesion factor descends with the train speed increase, this means that when train is run at high speed utilizable binding force has descended on the contrary.Raising along with train speed; Being increased to 350km/h with the speed of a motor vehicle from 300km/h is example, and it is about 40% that kinetic energy increases, when this part momentum transfer is gone out; If rely on disc brake purely, the temperature rise of brake disc, thermal stress etc. will face a severe test in the braking procedure so.Therefore; Service braking mode when 350km/h and above high speed train are necessary to consider to adopt non-sticking braking as in emergency circumstances brake mode or high speed; To remedy the defective of adhesion braking under the high speed damped condition, guarantee the safe and reliable braking of high speed train.On the 350km/h of research and development at present and above high speed train, carried out the research of these three kinds of non-sticking brake mode of linear eddy current brake, electromagnetic rail brake and aerodynamic braking.
Eddy current brake is the relative motion that utilizes excitation electromagnet and rail, in rail, produces eddy current, and the magnetic field interaction that magnetic field that eddy current produces and excitation electromagnet produce obtains and train working direction opposite effect force component.High-Speed Eddy Braking need increase brake equipments such as electromagnet on existing high speed train basis, increased the weight of train, and the energy of required consumption is big, and can produce negative effects such as electromagnetic interference and electromagnetic radiation pollution.
Electromagnetic rail brake is called the electromagnetic path braking again.It is through the electromagnet on the bogie of car being adsorbed in orbit and making vehicle slide the braking of generation in orbit.Similar with High-Speed Eddy Braking, brake equipments such as increase electromagnet also can increase the weight of the weight of train.Even more noteworthy: electromagnetic rail brake is to consume train momentum through producing heat with track friction, can produce abrasion to rail, and service expenditure is big.
Aerodynamic braking conducts a research from the aerodynamics angle; Some problems of having avoided these two kinds non-sticking brake mode of High-Speed Eddy Braking and electromagnetic rail brake to come out fully; It is to increase the wind area on the sense of motion with the wing plate that roof launches; The relative friction that utilizes atmosphere and wing plate is converted into heat energy with the kinetic energy of train, and along with flowing fast of air loose in atmosphere.It has the advantage of the following aspects: the wing plate that 1, utilizes roof to launch increases air resistance and produces braking force; Size square is directly proportional with speed; The high more then braking force of speed is big more, and this brake mode has premium properties when high speed, the defective of adhesion braking when having remedied 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 is changed, 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 simple relatively; 4, aerodynamic brake does not have wear part, compares with disc brake, and friction heat is very little, and the friction heat that produces also can loose in atmosphere at any time, has characteristics such as reliability height, service expenditure are low.
Summary of the invention
