Detailed description of the invention
Embodiment 1:
The two-way windage brake of a kind of high ferro train as shown in Figure 1 to Figure 3, comprises windage slipper, and passes through the first bearing of bearing hinge connection with windage slipper one end, and passes through the second bearing of bearing hinge connection with the windage slipper other end; And with the first bearing and the hinged bearing of the second bearing other end, and the grillage installed with bearing fit; Described grillage is additional or built-in is installed on EMU roof or/and EMU car body both sides; Described first bearing and the second bearing are telescoping mechanism.
Wherein, described first bearing and the second bearing can be cylinder or hydraulic actuating cylinder; Described plate is parallel to car body when regaining, and the windage slipper of external-added grillage is parallel with car body surface, and the windage slipper of built-in grillage can be fitted with car body surface; Built-in windage slipper is regained and is hidden in vehicle body side wall under non-working condition, and windage slipper tightly can be fitted with car body plane, does not affect EMU overall appearance effect and aerodynamic performance; Exhibition angular region ± 90 ° that described windage slipper and train direct of travel are formed.
Under EMU high-speed cruising state, when needing to adopt windage braking, be installed in the first bearing 2 on grillage 4 and be filled with pressurized air, piston rod stretches out, the side promoting to be installed on windage slipper 1 on bearing 5 stretches out car body 9 windward, with car body roof plate or framed side wallboard angled, thus stop the flowing of the outer sidewind of car body, produce air resistance, make train obtain windage braking force.When train reverse direction operation, be installed in the second bearing 3 on grillage 4 and be filled with pressurized air, the opposite side that can promote the windage slipper 1 be installed on bearing 5 stretches out car body 9 windward, with car body roof plate or framed side wallboard angled, thus the flowing of the outer sidewind of prevention car body, produce air resistance, make train obtain windage braking force.
Embodiment 2:
