Abstract

The invention provides a hinge type aerodynamic braking device, which is arranged in a containing space at the top surface of a train. The braking device comprises a wing body and a driving device, wherein the wing body is formed by a plurality of fin units arranged along the length direction of a train body, adjacent fin units are connected at least through hinges, and hinge positions are located on one side of the fin units close to the top surface of the containing space. The containing space is arranged along the length direction of the train body, the dimension of the containing space is no smaller than that of the wing body, and the tail end of the containing space is provided with an upward first inlet and outlet. The driving device can drive the fin units to move, and part of fin units of the wing body vertically and upwards extend out of the top surface of the train from the first inlet and outlet or withdraw back to the containing space. The hinge type aerodynamic braking device is simple in structure, good in stability and flexible and reliable in use.

Description

technical field [0001] The invention relates to railway vehicles, including braking devices for magnetic levitation trains, high-speed electric locomotives and high-speed EMUs, and in particular to a train braking device based on aerodynamics. Background technique [0002] With the improvement of train operation speed, safety issues will be paid more and more attention by people. As an important line of defense to ensure the safety of passengers, braking technology has been paid more and more attention. Especially the braking safety technology of high-speed trains with a speed of 350km per hour and above has become the focus of high-speed train research in all countries in the world. At present, on high-speed trains with a running speed of 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...
