FIELD: railway transport.
SUBSTANCE: invention relates to brake systems of freight cars, namely, to design of brake riggings installed on bogies to transmit force of brake cylinder to brake shoes interacting with wheels. Proposed brake rigging includes vertical levers. Upper part of one of levers is connected with tie-rod of car brake system, and upper part of other lever, with shackle of dead point holder. Lower parts of vertical levers are connected by brace, and in middle parts brake beams are hinge secured being suspended through swinging suspension from brackets of side frames and connected by elastic rod installed parallel to longitudinal axis of bogie. One end of said elastic rod is secured in guide of first brake beam, and other end is mounted in guide of second brake beam for reciprocation. Novelty is that proposed brake rigging is furnished with second elastic rod connecting brake beams in mirror like manner, each elastic rod being provided with limiting head on one end and secured from side of one of brake beams by means of clamp with two coaxial holes feted on elastic rod and arranged inside guide. Bent-on wall of clamp encloses one of webs of brake beam guide and rod head. Elastic rods are installed in parallel on end parts of brake beams between brake shoe and spacer. One rod is secured in guide of first brake beam, and the other, in guide of second brake beam.
EFFECT: provision of parallel release of brake shoes from wheel roll surface at preservation of simple design.
