The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As shown in Figure 1; A kind of windage brake equipment of high speed train comprises a wind wing plate 2 to be opened/closed that is arranged on the train body top board 1, is provided with streamlined reefer housing 3 around the wind wing plate 2; Streamlined reefer housing 3 is fixed on the car body roof plate 1; The opening direction of wind wing plate 2 be against the wind to, wind wing plate 2 by its unlatching of driving device controls and closure, actuating device is connected with control system under the car.
In train cruising process, wind wing plate 2 is in closure state; When train needs glancing impact, the control system accessory drive is opened wind wing plate 2, when wind wing plate 2 is opened to certain angle; Wind wing plate 2 produces running resistance; Thereby the generation brake action to remedy the defective of adhesion braking under the high speed damped condition, is guaranteed the safe and reliable braking of high speed train.
The windage braking conducts a research from the aerodynamics angle; Some problems of having avoided the adhesion braking mode to come out fully; It is the wind area that utilizes on the wind wing plate 2 increase sense of motions that launch on the roof; The relative friction that utilizes atmosphere and wind wing plate 2 is converted into heat energy with the kinetic energy of train, and along with flowing fast of air loose in atmosphere.The wind wing plate 2 that utilizes roof to launch increases air resistance and produces braking force, square being directly proportional of size and speed, and 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.In addition, the windage braking makes full use of this clean energy resource of wind energy, has the meaning of energy-conserving and environment-protective.And the windage brake equipment only needs roof wing plate installed position is changed, and with eddy current brake the change of bogie truck is compared; The windage braking is changed less to original vehicle structure, and the transformation cycle is short, design is simple relatively, and the windage brake equipment does not have wear part; Compare with disc brake; 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.
As shown in Figure 2, wind wing plate 2 adopts and the similar streamline structure of roof, not only can adapt to the car body profile of high speed train, can also effectively improve air flow field, reduces aerodynamics noise.The profile of streamlined reefer housing 3 adopts the streamline contour curved-surface structure; Be used to connect wind wing plate 2 and car body roof plate 1; The bulk flow that not only guarantees train is linear, also effectively improves the train aerodynamics performance simultaneously, reduce since wind wing plate 2 and streamlined reefer housing 3 be provided with train operation the time resistance that produces.
Under the normal circumstances, wind wing plate 2 is in closure state, smoothness continuous transition between wind wing plate 2 and the streamlined reefer housing 3, the resistance that is produced when further reducing train operation.
The opening direction of wind wing plate 3 is consistent with the service direction of train; Promptly adopt against the wind to as opening direction, actuating device is under the high speed damped condition, and wind wing plate 2 can be opened to maximum angle at short notice; Implement braking, can guarantee the stationarity in the opening process of wind wing plate 2 simultaneously.
