Abstract

The invention relates to a single wing plate operated aerodynamic braking device at least comprising a box body and a braking wind wing. The box body is fixedly connected at top of a train, the left side and the right side of the lower surface of the braking wind wing are connected with the left edge and the right edge of the inner portion of the box body respectively through link mechanisms, a pair of pin axis telescoping mechanisms are respectively arranged at the front edge and the back edge of the inner portion of the box body, a pair of supports corresponding to the pin axis telescoping mechanisms are respectively arranged at front edge and the back edge of the lower surface of the braking wind wing, a cylinder driving portion, a linear guide rail and a supporting pull rod are arranged inside the box body, the upper end of the supporting pull rod is connected with the middle portion of the lower surface of the braking wind wing, and the lower end of the supporting pull rod is driven by the cylinder driving portion to slide in the linear guide rail. Compared with the prior art, the single wing plate operated aerodynamic braking device has the advantages of high reliability, small occupy space, convenience in maintenance and mounting and the like.

Description

Technical field [0001] The invention relates to a braking device for railway vehicles such as magnetic levitation trains, high-speed electric locomotives and high-speed EMUs, in particular to a single-wing plate action type aerodynamic braking device. Background technique [0002] As the operating speed of trains increases, safety issues will attract more and more attention. The braking technology, as an important line of defense to ensure the safety of passengers, has received more and more attention. In particular, the braking safety technology of high-speed trains with speeds of 350km / h and above has become the focus of research on high-speed trains around the world. At present, on high-speed trains running at 300km / h at home and abroad, only adhesive braking is usually used, but the braking force of adhesive braking depends on the adhesion coefficient between the wheel and rail, and the adhesion coefficient decreases with the increase of train speed. It means that when the ...
