FIELD: transport engineering. SUBSTANCE: brake drive has brake chambers with spring energy accumulators 8. Spaces of energy accumulators are connected to pipeline 11 by means of electropneumatic valves 13. Electropneumatic valves have electromagnets 14, valve 15, return spring 16 and channel 17. Mounted on band brake valve 6 is contact 7 of control circuit 12 of electropneumatic valves 13. With contact 7 closed, valves 15 are closed and prevent compressed air from coming out of channels 17. With contact 7 open, spring 16 presses off valve 15, and compressed air passes into atmosphere along pipeline. EFFECT: enhanced safety on the road owing to prevention of sharp braking not controlled by driver. 1 dwg
Electropneumatic train brake control - has flow restricting non-return valves for even response in both systems, and separate valves for application and venting
