RAIL VEHICLE BRAKE LEVERAGE Russian patent published in 2005 - IPC

FIELD: railway transport; freight car brake leverages.

SUBSTANCE: proposed brake leverage contains two horizontal levers connected by tie-piece in middle part. Said tie-piece is made in form of H-piece. Webs of H-piece are arranged along middle part of corresponding horizontal lever and are provided with at least three holes, each. Same number of holes to form articulated joint between tie-piece and horizontal levers are made in middle part of each horizontal lever. End of one horizontal lever is hinge-coupled with rod of brake cylinder. End of other horizontal lever is hinge-coupled with bracket of brake cylinder cover. Opposite ends of horizontal levers are hinge-coupled with tie-rods. End of horizontal lever can be connected with tie-rod through brake cylinder rod projection regulator. Tie-rods are hinge-coupled with upper ends of vertical levers of car bogie brake leverages. Invention provides required braking force for freight car running along tracks of different gauge on bogies of different type with use of, both, cast iron and composition brake shoes.

EFFECT: provision of optimum values of mass and strength of tie-piece and length of horizontal levers.
