Description
Technical field
The utility model relates to rolling stock, comprises the brake equipment of magnetic suspension train, electric express locomotive and EMU etc., particularly a kind of following formula aerodynamic brake of going up.
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.
The utility model content
In order to solve the problem that exists in the prior art, it is a kind of based on aerodynamic braking wind wing that the utility model provides.
The technical scheme of the utility model is following:
A kind of following formula aerodynamic brake of going up comprises at least: braking wind wing, support, dovetail furrow guide rail and cylinder, and said support is arch; Stride and be located at the train vehicle body, be symmetrical set the dovetail furrow guide rail on the said support, on the said braking wind wing dovetail furrow is set; Form sliding pair with said dovetail furrow guide rail; Said train top is provided with notch, and said cylinder links to each other with braking wind wing, under air cylinder driven; Said dovetail furrow slides up and down in said dovetail furrow guide rail, makes said braking wind wing stretch out the train top via said notch or is retracted in the said notch.
As preferred implementation, the end face of said braking wind wing is provided with closing plate, and said notch edges is provided with sealing lip, and in the time of in said braking wind wing is retracted to said notch, said closing plate and sealing lip closely cooperate.
Said braking wind wing inside is skeleton structure, and said skeleton structure outside face covers the duralumin thin plate.
The beneficial effect of the utility model is: 1, braking wind wing is vertical opens, and only needs a metastable propulsive effort with braking wind wing jack-up, does not receive the influence that This train is bound for XXX; 2, braking wind wing is vertical opens, and has greatly saved the application force of driving cylinder, utilizes on the car existing source of the gas as propulsion source, uses cylinder to satisfy condition, and need not to install additional other propulsions source again; 3, it is inner that cylinder is placed on the braking wind wing skeleton, saved installing space on the one hand, on the other hand cylinder played a protective role; 4, dovetail groove type guide rail slide block structure can bear two-way function power, and motion stabilization, guarantees braking wind wing smooth opening and withdrawal; 5, under the condition of vehicle gauge and the permission of in-vehicle device space, improved the wind area of braking wind wing effectively, strengthened braking effect.
