Abstract:
An air spring air-supply control device, comprising an air intake pipeline (100), a connecting pipeline (200), a first exhaust pipeline (300), a second exhaust pipeline (400), a third exhaust pipeline (600), a first solenoid valve (201), a second solenoid valve (401), a third solenoid valve (500) and a controller, wherein the first solenoid valve (201) is arranged on the connecting pipeline (200); the second solenoid valve (401) is arranged on the second exhaust pipeline (400); the third solenoid valve (500) can communicate the connecting pipeline (200) with the second exhaust pipeline (400), and the third solenoid valve (500) can communicate the first exhaust pipeline (300) with the second exhaust pipeline (400); and the third exhaust pipeline (600) is arranged between the second solenoid valve (401) and the third solenoid valve (500), and communicates with the second exhaust pipeline (400). When a suspension system of a normal-conduction high-speed maglev vehicle malfunctions, air in an air spring can be exhausted by means of the air spring air-supply control device, so as to guarantee normal operation of the vehicle.
