摘要： A hydraulic motor brake for providing load holding torque to a hydraulic motor and comprising a housing, a plate fixedly mounted within the housing, a piston mounted for bi-directional translation relative to the plate along a longitudinal axis, and a plurality of friction-producing members arranged such that the piston and plate at least partially define a brake release chamber and the piston, normally biased in engagement with the friction-producing members to produce load holding torque, translates away from the plate and disengages from the friction-producing members to stop producing load holding torque in response to pressurized hydraulic fluid being received by the brake release chamber. 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.

摘要： A parking brake system is provided in which a parking brake state is obtained by forward movement of a parking piston (33) in response to the action of a parking control fluid pressure, and a forward operating state of the parking piston (33) is mechanically locked by a lock mechanism (43). Moreover, an input member (23) of a brake mechanism (11) and the parking piston (33) are connected by coupling means (35), a lock piston (44) of the lock mechanism (43) moves toward one side in the axial direction when the parking piston (33) moves forward, and a locking part (46) provided at one end of the lock piston (44) engages from the rear with a retaining part (45) provided on a middle section of the coupling means (35) while straddling the middle section of the coupling means (35). This enables an automatic parking brake state to be obtained by a simple structure without consuming power.

摘要： A disc or drum brake fluid pressure actuator incorporates a lock actuator strut acting on an inner part of a telescopic piston assembly, of which the inner and outer parts are normally rendered effectively unitary by pre-stressed spring which can, however, deflect under excess pressure to permit extension of the lock actuator strut when it is desired to operate the strut for parking purposes. An hydraulic control system for operating the actuator is also described and illustrated.

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 (X) so as to apply a braking force on friction pads when a fluid is introduced under pressure into the cavity, and having a determined operational travel, a wear compensation device (10) which defines a position to which the piston retreats into the liner by means of a mobile stop (11) that can be moved forward by the piston as a braking force is applied, and an elastic return member (16) returning the piston towards the retracted position bearing against the mobile stop. According to the invention, the mobile stop is reduced to a friction member rubbing against the liner, such that one of the faces of the friction member serves as a stop defining the retracted position of the piston, and the other of the faces serves as a support for the elastic return member, the elastic member having, when compressed, a sufficient increase in force in order to be able to push back the mobile stop in the event that the piston is not in contact with the friction pads while its operational travel is already exhausted.
