FIELD: transport.SUBSTANCE: invention relates to railway transport, particularly, to electric rolling stock braking systems. Electric rolling stock braking system comprises brake main line, air control valve, spare tank, extra tank, stepless axial regulator and two-step pressure relay. Stepless axial regulator comprises diverging weights secured at the cup to interact with moving thrust bearing interacting via elastic element with moving baffle for control over inlet valve. Moving baffle is provided with vent channel. Two-step pressure relay has one of control valves confined by a large moving baffle and small moving baffle interconnected by a rod. Transfer mechanism is composed of toothed rack secured at moving thrust bearing to interact with gear and cam fitted on the shaft together with said gear. Said cam interacts with the stop.EFFECT: simplified design, higher reliability and efficiency.4 cl, 1 dwg |
