FIELD: railway transport; brake systems.
SUBSTANCE: invention relates to brake system devices designed to control air pressure in train brake mains in emergency. Proposed train brake mains control device contains units to check and control parameters of air pressure in brake mains and unit to transmit and receive check and control information by radio channel to/from locomotive. Said units are secured on last car of train. Pressure transmitters are connected by output to brake mains parameters check and control unit. Input of first transmitter is connected through hose of last car to train brake mains before electromagnetic valve which serves as actuating mechanism of control unit. Input of second transmitters is connected to expansion reservoir with throttling hole installed after electromagnetic valve. Device contains also electromagnetic valve communicating with atmosphere in open state and used as required at braking. Said valve is connected directly to expansion reservoir.
EFFECT: possibility of emergency or service braking according to all requirements to braking process.
