FIELD: railway transport; brake shoes of rail vehicles. ^ SUBSTANCE: proposed brake shoe has metal skeleton-back with hole for cotter in central projection of shoe. Skeleton-back is made in plan in form of rectangle with side walls over entire length of shoe and with at least two bridges. Said bridges connect side walls being arranged symmetrically at both sides relative to central projection of shoe. Bridges are provided with fixing grooves for composite friction member arranged inside skeleton-back. ^ EFFECT: increased braking efficiency of shoe if water or ice get in friction zone, improved reliability of design of shoe in operation in cold climate and at frequent application of brakes. ^ 3 cl, 1 dwg |
