Abstract

1,030,527. Combined external and internal shoe drum brakes. GOODYEAR TIRE & RUBBER CO. Nov. 10, 1964, No. 45744/64. Heading F2E. A drum brake of the kind comprising a drum 1 in the form of a ring adapted to be gripped by blocks 27, 33 engaging both interior and exterior surfaces of the ring, respectively, includes a floating C-shaped member composed of elements 18, 20, 21 and 22, a piston 25 operating in a chamber 19 of element 18 and acting on block 27 via a sub-piston 28 guided in an opening 31 of element 22, and screws 29, 34 detachably attach the blocks to the sub-piston 28 and element 22, respectively. The element 18 is retarded to provide a bifurcated arm 10 (Figs. 1 and 4, not shown), pivoted at 11 to a torque plate 5 which is secured to axle 8, the position of pivot 11 causing a self-servo braking action. The pivot 11 comprises a sleeve 11a (Fig. 4, not shown) and a cap screw 11c screwed together and locked in relative positions providing a desired degree of friction between arm 10 and plate 5. A wheel 4 is journalled on the axle and carries a cup-shaped member 2 by which the drum 1 is attached to the wheel rim for braking the wheel. The opening 31 in element 32 is provided with a notch 31a giving a visible indication of wear of block 33, block 27 also being visible for this purpose. Grooves 31b guide a projecting portion 30 of the sub-piston 28 within the opening.
