FIELD: transport.SUBSTANCE: invention relates to rolling stock brakes. Proposed brake comprises electrically driven air control valve, spare tank, controller, brake cylinder, brake air line, control unit of said electrically driven air control valve and pressure gage. Said electrically driven air control valve comprises pneumatic part and electric part separated by control pressure chamber. Said electric part comprises solenoid valves of braking interconnected and connected with control unit of said electrically driven air control valve. Controller incorporates car load measuring unit including pneumatic damper, its rod making the car spring deflection meter. Pressure gage serves to measure control pressure chamber pressure of said electrically driven air control valve and is composed of cylinder and spring-loaded piston with rod. Controller adjustment unit is composed of electric contacts and isolators of said contact displacing relative to each other. Pressure gage cylinder is communicated with control pressure chamber. Pressure gage piston rod is rigidly connected with electric contacts. Isolator of electric contacts is rigidly connected with controller measuring unit rod. Electric contacts are connected in series with circuit of solenoid vale of aforesaid electrically driven air control valve.EFFECT: reduced consumption of electric power, increased rolling stock speed.2 cl, 1 dwg |
