DEVICE TO CONTROL AIR PRESSURE IN TRAIN BRAKE MAINLINE

摘要

FIELD: railway transport. SUBSTANCE: invention relates to auxiliary devices of brake system and makes it possible to check integrity of brake air mainline of train. Proposed device consists of monitoring unit installed on last car of train to transmit by radio channel information on air pressure in brake mainline to receiver installed in locomotive control cabin. Monitoring unit is made in form of air pressure pickup 6 connected to train brake mainline and to information input 10 of system unit 11 of processing and transmission of information by radio channel through antenna 12 to receiver. Pneumatic motor 15 coupled with electric generator 14 is connected to train brake mainline through preset maximum air pressure limiter which can be made in form of pressure relief valve. EFFECT: prevention of over-expenditure of air from train brake mainline and elimination of possibility of overloading in operation of pneumatic motor and electric supply circuit of information processing and transmission system unit. 3 cl, 2 dwg
