Abstract

1. A brake shoe of a railway rolling stock comprising a polymer friction element with a transverse U-shaped recess in it from the side of the working surface and a metal frame with a U-shaped protrusion in the central part, made in the form of a closed frame, pressed into the polymer friction element, and pressed over the frame of the back, made in the form of a perforated-corrugated metal curved plate, characterized in that in the perforated-corrugated metal plate of corrugation You have a longitudinal location relative to the polymer friction element, the height of which is made not less than the length of the perforated hole. 2. The brake pad of a railway rolling stock according to claim 1, characterized in that the lengths of each of the two sections of the back of the butt, extending beyond the U-shaped recess, are made with at least seven wave-length corrugations.

Description

yarmozny block of railway rolling stock.

The claimed utility model relates to railway transport, in particular to the structural embodiment of the brake shoes of rail vehicles.

A composite brake pad of an iron-working vehicle is known, consisting of a friction material and a metal back with an eye for passing checks, moreover, the boot is made in the form of closed frames pressed into the friction material along the perimeter of the chute pad, the inner parts of which are mutually overlapped and bent outward of the rear part of the head , orazuya ear / dsh misses - yaniya checks is, wi A.S. UUCP No. 3It403 dated 01.01.1973 class ZyV 7 / C2.

This brake shoe has a high drying resistance, but does not impair the good: thermal conductivity, due to which its wear resistance is reduced.

the known brake shoe due to the imperfect design of the back sections, at the time of braking and the resulting loads in the longitudinal direction of the back of the shoe does not sufficiently prevent wear of the back of the shoe.

the proposed brake pad allows to eliminate the disadvantages of the known and significantly increase the wear resistance during its operation. Why, in a perforated-corrugated metal curved plate, the corrugations have a longitudinal location relative to the polymer friction element. 11th height of the corrugation is made not less than the length of the perforation otvergiya. lipw weft. length every 10 of two plots of the back of the butt, extending beyond the ii-shaped recess is made with the presence of at least seven corrugation waves.

Induction of the shoe pads is carried out by means of pressing in a mold, for this purpose a friction polymer element 2 is formed in the mold, Next, a blank of wire reinforcement is placed), which forms a wire mesh frame I. Pressing is performed, and heat treatment is carried out in a known manner.
