BRAKE PAD FOR BUSES AND TRUCKS

摘要

FIELD: transportation.;SUBSTANCE: brake pad for buses and trucks contains a metal frame and a polymer composite friction element fixed on it, in the central part of which a groove is made. The metal frame is made with nine holes, eight of which are arranged symmetrically to the groove outside the area of the groove, and the ninth is located directly in the area of the groove. The friction element is provided with projections disposed in the bores of the frame. The length of the groove and the depth of the groove are chosen from the relationship: L/H=6.0-7.0, where L is the length of the groove, H is the depth of the groove.;EFFECT: reducing the possibility of destruction of the friction element during the operation of the shoe by more efficient compensation of stresses in the central part of the friction element.;2 dwg
