BRAKE CONTROL SYSTEM OF LOCOMOTIVE-DRIVEN TRAINS Russian patent published in 2004 - IPC

FIELD: railway transport.

SUBSTANCE: invention can be used for remote control of processes in train brake system (braking, release, overlapping and maintaining charging pressure in brake main line) of locomotive-driven trains both under automatic control and under action of separate remote control members. Proposed brake control system contains driver's valve connected with brake main line and communicating through metering and first supply channel with reducer, supply main line, compensating tank communicating through main line with driver's valve, and stabilizer. Supply main line is connected to driver's valve through first electromagnetic valve. Second electromagnetic valve is installed in channel communicating driver's valve with stabilizer. Main line communicating driver's valve with compensating tank is connected with atmospheric channel through first disconnecting cock and first electropneumatic valve. Second electropneumatic valve is installed into second supply channel connecting driver's valve with reducer. Supply main line is connected through second disconnecting cock and third electromagnetic valve with first supply channel connecting reducer with driver's valve. Fourth electromagnetic valve and third disconnecting cock are connected between supply main line and brake main line. Control circuits of electromagnetic valves and electropneumatic valves are connected with driver's controller. Pressure transmitter is installed additionally on compensating tank. Output of transmitter is designed for connection to train automatic remote control system. Invention provides possibility of remote control of processes in train brake system (braking, release, overlapping and maintaining charging pressure in brake main line) in trains driven by locomotive both under automatic control and under action of separate remote control members.

EFFECT: improved reliability owing to decrease of mechanical wear of driver's valve spool.
