BRAKE RIGGING

摘要

FIELD: railway transport. SUBSTANCE: invention relates to design of power drive of four-axle freight car brake rigging. Proposed brake rigging of four-axle freight car contains pneumatic brake cylinder acting onto brake shoes by tie-rods, and rear and head horizontal levers intercoupled by tie-bar. Said tie-bar is furnished with travel limiter. Tie-bar is connected with horizontal head lever through slide block, and tie-bar travel limiter is made spherical. Invention prevents appearance of rod bending forces which excludes wear of cup and hinge joints. EFFECT: improved operation reliability of brake rigging. 1 dwg
