FIELD: transport mechanical engineering; drum-type braking units of trucks and buses. SUBSTANCE: proposed friction lining is made from polymer friction composite material in form of cylindrical shell of varying thickness which is formed by non-coaxial cylindrical surfaces with parallel axes of rotation and flat side surfaces. Side surfaces bounding the lining consist of two engageable planes located at angle relative to each other. Novelty of invention consists in excess of area of radial flat surface over area of non-radial flat surface which is engageable with it. Area of radial flat surface on thin end of lining corresponds to area non-radial flat surface which is engageable with it. Area of flat radial surface of thin end of lining is lesser than area of flat radial surface of thick end of lining and area of flat non-radial surface of thin end exceeds area of flat non-radial surface of thick end of lining. EFFECT: enhanced reliability; improved service characteristics; reduced cracking. 2 dwg
