FIELD: transport.SUBSTANCE: invention relates to railway transport, namely, to railway vehicle braking clamps. Brake comprises air pressure control valve assembly with two- and three-pressure valves and tank, extra tank, brake cylinder, automatic control mode with measuring and adjusting units and engineman valve. Three-pressure member incorporates the main and equalizing pistons fitted on one axle and check valve. Main piston rod is hollow. Equalizing piston has through axial bore to make its rod interact with spring-loaded brake valve of the main piston. Automatic control mode measuring unit cylinder is rigidly connected with the car section with no springs. Compression spring in contact with piston rod is connected by its other end with air pressure control assembly. Automatic control mode adjusting unit is composed by two single-arm levers articulated by one end via horizontal shaft secured at measuring unit piston rod and rigidly coupled with torsion spring. Opposite end of the first single-arm lever is articulated with the car section with no springs while other end of the second single-arm lever contacts with equalizing piston outer side.EFFECT: higher capacity of railway.1 tbl, 1 dwg |
