Title: Improvements in disc brakes
IPC: F16D65/18
Filed: 1957-06-17
Abstract: 840,392. Disc brakes. BENDIX AVIATION CORPORATION.. June 17, 1957 [June 21, 1956], No. 19052/57. Class 103 (1). A disc brake includes a pair of friction pads carried by a non-rotatable housing straddling part of the disc, and adapted to be engaged against opposite faces of the disc by fluid motor means carried by the housing, means between the pads and the motor means permitting the pads to slide and tilt on brake application to conform with the disc faces. Cylinders 26, having shoulders 28 held by screws 30 against the outer surfaces of two dished plates 14, 18 forming the housing, each contain an 0-ring 34 in frictional engagement with a piston 32. A ring 46, in sliding engagement with a washer 44 secured to an extension 42 of the piston 32, has a spherical recess seating a spherical cap 48 connected by an extension 54, Fig. 3, to the friction pads 50 comprising a backing plate bonded to a friction lining 52; the radius of the sphere from which the cap is cut and the height of the cap being such that the diameter of the cap is almost that of the piston. Due to the ball and socket connection, the linings are self-aligning and can be applied with equal pressure over their surfaces to the disc in spite of irregular wear. The brakes are released by springs 56 bearing between the external surfaces of plates 14, 18 and washers 58 fixed to pins 56 passing through aligned holes in the plates 14, 18 and the backing plates on which seat the heads of the pins, the springs 56 being strong enough to exert a pressure between the cap 48 and seating ring 46 sufficient to overcome external vibrations to prevent unintentional rotation of the ball and socket connection. Notches 64, Fig. 4, one in each end of the backing-plate, engage pins 66 acting as stops to arrest movement of the friction pad unit 52, 50, 48, 46 when the linings 52 engage the disc, the ring 46 sliding on washer 44 to prevent the cylinders 26 being subjected to stress. A yielding member 68 housed in a recess between washer 44 and piston 32 acts as an automatic clearance adjuster, this clearance being the distance j between the washer and member 68, Fig. 1, which is of steel and is provided with two diametrically opposed projections (Fig. 5, not shown) kept in frictional engagement with the cylinder, the distance between the ends of these projections being slightly greater than the diameter of the cylinder. On application of the brakes the member 68 is moved by the piston 32 but on release of pressure in the cylinder 26 the friction block unit can only return until the washer 44 contacts member 68 so establishing the correct clearance. Specification 830,236 is referred to. Reference has been directed by the Comptroller to Specification 688,382.
