Hybrid vortex rail braking system

The invention discloses a hybrid vortex rail braking system. In the technical scheme, lifting air cylinders are symmetrically arranged on both sides of a Y-shaped rotating pivot between a side frame of a truck frame and a magnetic system of a brake, an air braked handling system is respectively connected with the two lifting air cylinders, the piston rods of the two lifting air cylinders are connected with the magnetic system of the brake, the rod-free cavities of the two lifting air cylinders are connected with the side beam of the truck frame, and a wear plate on the bottom surface of the magnetic system of the brake is arranged to be opposite to a rail. The invention can control the power and the deceleration process through positive excitation of the exciting coil and regulation of the exciting current, thereby achieving the effect of actively controlling the deceleration. The magnetic attraction between the magnetic system of the brake and the rail can be reduced through reverse excitation of the exciting coil, thereby facilitating the lifting of the magnetic system of the brake. Simultaneously, the invention has the advantages of simple structure, energy conservation, high reliability, light weight and the like, and not only can be applied in high-speed railways, but also has broad application prospects in maglev trains, urban rail transits and other fields.
