Abstract

1,020,452. Disc brakes. GIRLING Ltd. April 25, 1963 [May 3, 1963 (3); May 13, 1962], Nos. 12674/62, 12675/62, 12676/62 and 14322/62. Heading F2E. In a disc brake of the kind in which a directly actuated friction pad 22 is adapted to be brought into engagement with one face of a rotatable disc 10 by actuating means 23 located in one limb of a caliper or housing which straddles a portion of the periphery of the disc, a friction pad 25 located in or on the other limb of the caliper being brought into engagement with the opposite face of the disc by the reaction on the caliper, the directly actuated friction pad 22 is guided in a straight line for movement towards and away from the disc in a direction which is inclined with respect to a line at right angles to the surface of the disc in a direction such that the directly actuated pad is guided towards the disc in the same direction as the normal direction of disc rotation, such that when the friction pad is applied to the disc the frictional engagement between the pad and the surface of the disc produces a servo or selfenergizing action which increases the retarding effect of the brake. In the disc brake illustrated in Fig. 2 the piston 23 is adapted to be moved by fluid under pressure supplied to the outer end of the cylinder 24 and, through a wedgeshaped block 21, the friction pad 22 is moved into frictional engagement with the adjacent face of the brake disc 10 and the caliper, formed by a bridge piece 11 (Fig. 1, not shown), and two spaced parallel bolts 14, 15 inclined at an angle of 45 degrees to the plane of the disc, draws the friction pad 25 into engagement with the opposite face of the disc. The force exerted by the piston on the friction pad 22 has a component in the direction of movement of the surface of the disc with which the pad engages, the disc being rotated in the direction indicated by the arrow, and the tendency of the pad to be carried round the disc urges the block or carrier 21 to enter into engagement with the inclined abutment surface 18 which exerts a force on the pad urging it towards the disc so that the brake has a powerful self-energizing action. Alternative embodiments are disclosed in the Specification including a caliper which is adapted to pivot instead of sliding relative to the disc (Figs. 3 and 4, not shown), an arrangement similar to that disclosed in Fig. 2 but having a roller member between the wedgeshaped block 21 and the abutment surface 18 (Figs. 5 and 6, not shown), different forms of the brake in which the actuated friction pad is applied to the disc by pistons working in fluid pressure cylinders of which the axes are at right angles to the face of the disc but the directly actuated friction pad 22 is adapted to be guided at an angle 45 degrees to the plane of the disc (Figs. 7-9 inclusive, not shown), and a split caliper arrangement (Figs. 10 and 11, not shown).
