BRAKE BLOCK OF RAILWAY VEHICLE Russian patent published in 2008 - IPC F16D65/04 B61H1/00 F16D69/02 

FIELD: transport.

SUBSTANCE: invention refers to railway transport, namely to brake blocks of railway vehicles. Brake block contains composite friction element, wire framework, solid insert located in central part of block and pressed into composite friction element. Wire framework is essentially two closed up frames around block periphery pressed into composite friction element in the rear part of brake block. Inner parts of two closed up frames overlap each other are folded outside rear part of brake block forming an eye for a splint. The block contains in its rear part wire-mesh or perforated metal sheet pressed into composite friction element. Insert has slot in its upper idle part pressed by composite friction element with orifice for splint and cantilevers symmetrically located over insert length from each side. Upper idle part of insert is put in wire frame and jammed in it. Enhancement of strength, reliability of brake block construction, tool-life gain are reached.

EFFECT: enhancement of strength, reliability of brake block construction, tool-life gain are reached.
