摘要： The invention relates to a brake actuator for an aircraft hydraulic brake, which is intended to be added into one of the cavities of a brake ring, the actuator comprising: a liner (1) designed to be housed sealingly in the cavity of the ring; a piston (3) mounted to slide sealingly in the liner along an axis of sliding so as to apply a braking force when a fluid is introduced under pressure into the cavity; a wear compensation device (10) which defines a position to which the piston retreats into the liner by means of a mobile stop (11; 111) that can be moved forward by the piston as a braking force is applied; an elastic return member (18) returning the piston towards the retracted position bearing against the mobile stop; according to the invention, the mobile stop is associated with a notched indexing member (13) allowing the mobile stop to move under the thrust of the piston, but preventing any return motion of the mobile stop with respect to the liner.

摘要： A vehicle brake control device is configured to correct deformation failure of a seal member and inhibit insufficient pullback of a pressing member caused by insufficient deformation of the seal member. Within a time period from a start of a lock operation to an end of the release operation, a W/C pressure is automatically increased and insufficient deformation of a seal member is corrected. It is thus possible to generate a large restoring force by the seal member when pulling back a piston, and the piston can be pulled back based on the restoring force. The piston is therefore sufficiently moved, and it is possible to inhibit insufficient piston pullback. Further, it is possible to cause a brake pad to be separated from a brake disc by a predetermined distance, and it is possible to inhibit a feeling of drag of a brake from being imparted to a driver.

摘要： The invention is directed to a brake actuator of a vehicle which provides for a hydraulic reset in such a manner that a defined distance is always present between the brake lining 26 and the brake disc in the rest position of the friction brake. The brake actuator includes an electric motor 2, a hydraulic transmission 16 having a hydraulic chamber 22 with a first hydraulic piston 14 and a second hydraulic piston 18 and a second hydraulic cylinder 20. The brake actuator also includes a spindle unit (8, 10) located between an electric motor 2 and the hydraulic transmission 16. A further hydraulic chamber in the form of a readjusting chamber 28 is also provided. This additional chamber is closed off with a compensating piston movable relative to the ambient. The additional chamber 28 is connected to the first hydraulic chamber 22 via an opening 44 located in the second hydraulic piston 18. The opening 44 is provided with a check valve to permit flow to the pressure chamber 22. In the event of an exchange of the brake lining, the first hydraulic piston 14 is driven back so far that it clears an opening 40 of a reset channel 36 located between the pressure chamber 22 and the readjusting chamber 28. A further check valve 38 secures the reset channel 36 with respect to the readjusting chamber 28.

摘要： A clutch or brake unit is described with an automatic wear adjustment mechanism.Clutches and brakes operate by the engagement of friction members (4,6) which experience wear in use requiring a larger stroke of the unit to effect engagement. This results in delayed clutch or brake operation which can be a serious disadvantage where prompt action is required. Conventionally this wear has been compensated by replacement of the worn friction members or by manual adjustment of them resulting in temporary disablement of the unit and requiring service personnel time.In the inventive unit, friction members (4,6) are mounted between pressure members (10,2) and an actuator (12) operates against a backing member (15) to effect clutch or brake actuation and de-activation by movement of the friction members towards and away from each other, and the position of at least one of the pressure members is adjusted automatically in response to wear of the friction members. Sprags, ratchet mechanisms, screw threads and tension springs are alternatively described for adjusting this position and the wear can be sensed by a proximity switch or microswitch. Pneumatic and hydraulic mechanisms are also described.

摘要： A hydro-pneumatic actuator for providing a two-stage buildup of the hydraulic output pressure. A primary hydraulic piston, to which a pneumatic input piston actuator is connected, acts in a larger bore of a hydraulic cylinder to transfer fluid via a central passage in a spring-loaded, differential area, secondary hydraulic piston, that is coaxially disposed in the hydraulic cylinder in spaced-apart relationship with, and downstream of, the primary piston. A larger face of the secondary piston is in the larger bore and the smaller face is in a reduced diameter bore of the hydraulic cylinder, so that a pressure buildup in the hydraulic cylinder effects actuation of the secondary piston to close a check valve and thereby inter-fluid communication between the larger and smaller bores of the hydraulic cylinder via the central passage. The smaller face of the secondary piston is therefore effective to transmit the hydraulic force with a high gain multiplication factor following attainment of an initial predetermined force in low gain.The arrangement includes a displacement cylinder to measure the pneumatic piston stroke and an expansion chamber into which fluid is drawn from the reservoir when piston stroke is excessive for subsequent transfer to the hydraulic cylinder.

摘要： A hydro-pneumatic brake actuator arranged with a slack adjuster piston and one-way check valve device in the hydraulic path between a hydro-pneumatic actuator and a power piston, to which a friction brake element is connected for engagement with a vehicle wheel tread or brake disc during a brake application. During a brake release, the one-way check valve closes a passage through the slack adjuster piston to cause the piston to shift from its one extreme position to the other extreme position with the fluid flow, as the hydro-pneumatic actuator is moved from its application position to its release position. This in turn draws hydraulic fluid from the power piston chamber into a clearance volume created by shifting of the slack adjuster piston, and accordingly forces the power piston to retract a predetermined distance corresponding to the capacity of the clearance volume and the effective area of the power piston, thereby maintaining a constant brake shoe clearance during brake release.

摘要： Displacement of the magnetic body of a spring engaged, friction brake or clutch, is automatically adjusted for releasing operation by a valve controlled fluid pressure resisting stop device. Movement of a spring loaded armature in response to wear of a friction disc engaged therewith, displaces a piston confining a pressurized body of fluid by opening of a valve from which a valve rod extends to form a limit stop engaged by the magnetic body that is displaced by the armature in one direction.
