Hardened structure.
The purpose of the present invention is achieved through the following technical solutions:
A kind of hardened structure of umbrella windage for rail vehicle braking, installation are braked for windage on the rail vehicle, should
Cloth made from the hardened structure of windage several pieces of hardboards as made from hard material and pliable material is alternatively formed, and is movably arranged on rail
Road outside vehicle when windage plate is opened, forms umbrella-shaped structure, provides brake force using windage for high speed railway car；Windage plate
When contraction, it is consistent with car body streamline for collapsing.
Further, the windage plate is installed on vehicle by the driving mechanism dug, opened or closed up.
Further, the driving mechanism includes motor, the lead screw guide rails being connected to motor and is set in lead screw guide rails
Sliding block, between the windage plate and sliding block by connecting rod connect, by motor drive lead screw rotation, and then drive be set to silk
Sliding block on thick stick guide rail is moved along lead screw guide rails, is connected between windage plate and sliding block by connecting rod, is controlled windage plate with this
It opens and collapses.
Further, the cloth and hardboard carry out split connection, form a whole face after opening.
Further, the hardboard is quadrangle or triangle, and the cloth is set between adjacent two pieces of hardboards, and phase
Spring assembly is set between adjacent two pieces of hardboards, spring assembly has the function of self-constriction.
Further, half umbrella is formed after the windage plate expansion, the angle between the car body of rail vehicle is 80-
90°。
Compared with prior art, the present invention provides a kind of umbrella-shaped structure windage plate, can be mentioned using windage for bullet train
For effective brake force.The present invention makes bullet train in braking process by using air, increases brake force, improves system
Dynamic effect, and it is pollution-free in braking process, and lossless, energy conservation, environmental protection has apparent superiority, is compared to lifting
Formula windage plate takes up space smaller in non-brake state.
