Abstract

1,019,982. Disc brakes; fluid pressure control of brakes. G. E. SETTLE. Aug. 1, 1963 [May 15, 1962], No. 18614/62. Headings F2E and F2F. A disc brake having self-energizing properties comprises a pair of coaxial spaced discs between which is located a first expander which applies pads to the inner disc faces, the first expander being pivoted to a fixed support for movement as a result of the drag forces acting on the pads, such movement being adapted to apply an amplified operating force to a second expander applying pads to the same or another pair of coaxial discs. In one embodiment, Fig. 2, a pair of discs 10 is formed integrally with a hub 11 and the inner faces are engaged by pairs of pads 15 associated with cylinders 13, 14 of which the former is pivotally mounted and supplied with hydraulic pressure by a master cylinder. The resulting drag forces on the pads causes pivotal movement of the cylinder to operate a second master cylinder for supplying pressure to the other cylinder 14. In Fig. 5 two such pairs of discs 27 are shown each having first and second cylinders 26, 30, respectively. First master cylinder 25 operated by pedal 23 supplies fluid to cylinders 26 which on pivotal movement operate separate master cylinders 29 which are interconnected by a pipe 31 leading via a balancing chamber 33 to a pipe 32 connected to the cylinders 30. A pipe 34 leads to other brakes on the vehicle while an additional control pressure is fed into the system via pipe 35, this being supplied by an oil pump driven from the transmission shaft, an inertia flywheel device, or a centrifugal governor, so that the pressure supplied to the cylinders 30 is dependent upon speed or/and deceleration of the vehicle. In a second embodiment (Fig. 4, not shown), a pair of discs 16 are joined by a peripheral annulus 17, the space between the discs which accommodates first and second cylinders 18, 19, being cooled by circulation of air through central opening 21 and peripheral ventilating tubes 22.
