FIELD: transport.SUBSTANCE: invention relates to disc brake. Proposed brake comprises brake beam calliper (1) surrounding the brake disc (2) and brake shoe-linings (3) to be pressed against disc (2) both sides, one can be actuated on clamp side by the cam of clamping device brake lever (5) turning about the pin. Besides, this brake comprises the self-reinforcing device that features self-reinforcement factor selected so that after braking this brake releases automatically. Compressed air brake cylinder push-rod can act on lever (5). Said lever (5) thrusts on at least one ball-like support element (10) in calliper (1) that makes the cam pivot pin. Said element (10) abuts on support ball (9) located in direction of push-rod action above support element (10) and positioned in brake plunger (6) connected with lining (3) located on clamp side. Pressure plungers (7) are arranged on both sides of plunger (6) and spaced apart. One end of said pressure plunger rests on clamp (1) while opposite end thrusts via support ball (16) on lining (3). Pressure plunger (7) is secured in guide plate (4) arranged to displace to the axis of brake disc (2) in the brake mechanism shield (8).EFFECT: optimised design, weight and sizes, higher efficiency.9 cl, 4 dwg |
