The invention provides a hydraulic drive aerodynamic brake device with a single wing plate. The hydraulic drive aerodynamic brake device comprises a box body which is arranged on the top of a train, wherein the box body is connected with a brake air vane; the left and right sides of the lower surface of the brake air vane are respectively connected with the inside of the box body through a link mechanism with a rotating shaft in the middle; each link mechanism is connected with a hydraulic cylinder arranged inside the box body; clamping shafts are arranged on the front and rear ends of the lower surface of the brake air vane; four U-shaped clamping grooves, two linkage rods and two drive cylinders are arranged inside the box body; movable pins with grooves are arranged at two ends of the each linkage rod; compression springs are arranged between the linkage rods and the movable pins with the grooves at the two ends of the linkage rods; holes for insertion of the movable pins with the grooves are arranged on the U-shaped clamping grooves; and the movable pins with the grooves are matched with the U-shaped clamping grooves and the clamping shafts under the drive of the drive cylinders for controlling the opening and the closing of the brake air vane. The hydraulic drive aerodynamic brake device has flexibility in operation and good stability.
Description
technical field [0001] The invention relates to a braking device for railway vehicles, including magnetic levitation trains, high-speed electric locomotives and high-speed EMUs, and in particular to a hydraulically driven aerodynamic braking device for a single-wing plate. 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 decrea...
