<p>Improved brake assembly which may be utilized to automatically brake a driven shaft or the like. The brake assembly (18) includes a rotatable brake disc (26) about which a fixed brake pad (27) on one side of the disc and a movable brake pad (28) on the opposite side of the disc are automatically actuated to engage and disengage the disc. The actuating means includes a hydraulic ram assembly (40) incorporating a piston (41) biassed by a coil spring (43) towards the engaged position. An actuating lever (37), connected to the ram, rotates the movable brake pad, which, by means of complementary mating ramp faces or helical inserts (34) received within the complementary annular recesses (32, 33) urges the brake pad into engagement with the rotatable brake disc.</p> |
