The other end of bar 7 is connected by bearing pin with connecting rod support 26.
After with said structure feature, with reference to shown in Fig. 2 and Fig. 3, the present invention can be implemented by procedure below：
With reference to shown in Fig. 1 and Fig. 2, when train normally travel, i.e., when need not brake, wing plate is horizontal.Now
Hydraulic cylinder is in contraction state, and crank and connecting rod are driven by hydraulic push rod, and then wind wing plate 2 is solid in the presence of convergent force
It is scheduled on non-brake horizontal level.Such as Fig. 2, now, hydraulic push rod is in ejection state so that crank and connecting rod bending and then shape
Into the convergent force of stabilization.
With reference to shown in Fig. 1 and Fig. 3, when train needs to be braked, windage of the opening direction towards current of traffic
Brake unit preferentially plays a role.Such as Fig. 3, now, hydraulic cylinder is in extended state, and crank and company are driven by hydraulic push rod
Bar, wind wing plate 2 is released and is upturned.Wind wing plate 2 is opened to rapidly vertical position under the wind-force effect that train operation is produced
Put.Specifically, if by taking the visual angle of Fig. 1 as an example：When train toward left direction from the right side from advancing in figure, then be in startup figure on the right side of
Brake unit, under the tensile force effect of right side hydraulic cylinder, while connecting rod jack-up three o'clock wind wing plate 2, is driven by gear 26
The rotating shaft in another left side turns direction and rotates along opposite axle, with this, while opening the wind wing plate 2 of left hand brake unit.So, in system
When dynamic, two wind wing plates 2 of brake unit play a role simultaneously, and under this state, the hydraulic cylinder of left hand brake unit is in laborsaving
State, only has Auxiliary support to act on its connecting rod；Conversely, when direction is advanced from left to right during train is by figure, then in startup figure
The brake unit in left side, similarly, on right side, hydraulic cylinder produces tensile force, so that jack-up left side and drives right sided cell at wind wing plate
Wind wing plate, now, the hydraulic cylinder of right side brake unit is at laborsaving state, only has Auxiliary support to act on its connecting rod.
After above-mentioned implementation process is completed, following characteristics of the present invention should be able to be embodied：
This invention simplifies configuration settings and human users, and significantly improve wind effects.Either in the sky to vehicle
Between, the aspect such as structural strength, weight and design difficulty will be much better than existing windage Brake Design.
The above-mentioned description to embodiment is to be understood that and apply this hair for ease of those skilled in the art
It is bright.Person skilled in the art obviously easily can make various modifications to these embodiments, and described herein
General Principle is applied in other embodiment without by performing creative labour.Therefore, the invention is not restricted to above-described embodiment,
Those skilled in the art's announcement of the invention, does not depart from improvement that scope made and modification all should be in this hair
Within bright protection domain.
