1496154 Hydraulic brake actuators; wear compensation GIRLING Ltd 21 April 1975 [8 May 1974] 20369/74 Heading F2F An hydraulic brake actuator comprises a cylinder 1, a piston having an annular outer part 6 telescopically receiving an inner part 7, pre-stressed resilient means 9 between the parts capable of transmitting normal braking forces, pressure seals being provided between the outer part and both the cylinder and the inner part, and a locking strut 12 which acts between the inner part and the cylinder 1. The locking strut engages by a reversible helical thread with the inner piston part 7, has a head 13 with a clutch face 14 which is urged by a spring 18 against a normally fixed member 16 but is displaceable therefrom by an hydraulic motor 24. Should the strut 12 jam a plug 23 is removed from the cylinder 1 when a plunger 22 disengages from between peripheral teeth on the member 16 which is then rotatable on a bearing 17. In normal use a chamber 28 is pressurized to apply the brakes and the locking strut compensates for wear by rotating in the piston part 7, which is prevented from rotating by an extension 11 engaging a back plate 3, when piston displacement exceeds Ihe thread clearance. With hydrostatic brakes the brake is locked by supplying higher fluid pressure to the chamber 28 to compress the spring washers 9 when the strut rotates to engage the clutch member 16 and then releasing the pressure. The brake lock is released by pressurizing the chamber 28 again to take up the spring loading, actuating the motor 24 through a line 27 at a still higher pressure to disengage the clutch, relieving the chamber 28 and then relieving the motor 24. With power brakes pressure fluid is supplied to the chamber 28 and at a higher pressure to the motor 24 during normal braking so that the strut 12 can spin before the thread clearance is taken up to provide a smaller pad clearance than with hydrostatic braking. To lock the brake the cylinder 28 is pressurized at a high pressure to compress the spring 9. A power braking system, Fig. 2, with dual circuits to brakes at 4 wheels comprises two pedal valves FCV for service braking and two hand valves HCV which are linked to or integral with respective locking control valvesL and are used instead of the pedal valves for lock actuation. For parking the hand valves supply fluid through the pressure reducing foot valves to the cylinder chambers 28 and through the valves L to the motors 24, then relieve the motors 24 and finally relieve the chambers 28.

The hydraulic motor brake further comprises a wear plate with the brake housing and wear plate defining bores arranged in coaxial alignment with threaded bores of the hydraulic motor for detachably attaching the hydraulic motor brake to the hydraulic motor as a self-contained unit.
69 LIN-XIE BRAKE US15698668 2017-09-08 US20180080516A1 2018-03-22 Yong Lin; Jianping Xie
A Lin-Xie brake used by a mine hoist, a car, a high-speed train, etc. Gas springs are used to replace belleville springs, and a positive pressure is also always applied to brake pads to both ensure and increase the brake reliability and a positive pressure per unit area. And the Lin-Xie brake resolves problems such as deformation of the belleville springs, a serious change in an elastic force, sudden cracking and decompression, inconvenient monitoring, and a manufacturing difficulty. For the Lin-Xie brake, a brake head floating structure is used to reduce a requirement on end face runout of a brake disc. An oil-gas linkage plunger pump is used to replace a hydraulic station, which greatly reduces manufacturing costs, and reduces energy consumption. The Lin-Xie brake is an ideal product to replace medium or large-sized Lin-Xie brakes used by existing mine hoists, cars, high-speed trains, etc.
