RAILWAY VEHICLE BOGIE BRAKE

摘要

FIELD: transport. ^ SUBSTANCE: invention relates to railway transport, particularly, to rolling stock braking equipment. Brake comprises baking line. Braking line is communicated via air control valve with standby reservoir and primary braking cylinder pivoted to bogie. Braking cylinder piston is connected via rod and two-arm lever with brake shoe control lever gearing. Braking hollow cylinder piston is shaped to cylindrical barrel. Spring-loaded plunger displaces inside said piston to interact with circular ledge of the barrel. Barrel iner chamber communicates with piston rod hollow space and, via flexible pipeline, with spare tank. ^ EFFECT: ruled out spontaneous rolling at brake depletion. ^ 1 dwg
