Zusammenfassung: | FIELD: machine building. ^ SUBSTANCE: brake block contains a polymer friction composite material with U-shaped transverse recess made on its working surface. The polymer friction composite material is fixed on a metal frame with U-shaped ledge in its central part. The said composite material incorporates an additional polymer friction element containing 40 to 96% of metal chips pressed in along the perimeter of the U-shaped recess on the working surface. ^ EFFECT: greater distance run between overhauls of the wheel pair. ^ 2 dwg |
