FIELD: railway transport; brake shoes of rolling stock.
SUBSTANCE: proposed brake shoe contains metal wire frame with backing and with hole for cotter in central projection of shoe, and friction part with hard inserts. Insert made of metal in form of rectangle in longitudinal section with side walls over entire length of shoe and with, at least, two bridges from each side from central projection of shoe. Bridges contain fixing cavities for frame fittings, and composite friction element is arranged inside insert. Invention provides increase of braking efficiency of shoe if water or ice gets into friction zone, improves reliability of design of shoes operating in cold climate and frequent application of brakes.
EFFECT: increased service life of wheels.
