摘要： A latching mechanism for a brake actuator is provided. The latching mechanism comprising an annular flange and a plurality of resilient elements extending radially inwardly from the annular flange. Each of the plurality of resilient elements comprises a U-shaped cross-section and a tooth on a radially inner end. The tooth is configured to conform to and engage with ratchet teeth of a wear compensation sleeve of a brake actuator.

摘要： A motor sub-assembly for an electromechanical brake actuator of an aircraft wheel includes a casing, a shaft mounted in the casing, and an electric motor mounted in the casing rotate the shaft, the shaft having an end connected to a screw-and-nut assembly to exert a force on a stack of disks for braking the aircraft wheel. The shaft has a first set of teeth and the motor sub-assembly has a shuttle mounted to slide relative to the casing and provided with a second set of teeth. The motor sub-assembly includes a selector mechanism that moves the shuttle selectively between first and second positions in which the first set of teeth is engaged and disengaged with the second set of teeth, respectively. The motor sub-assembly includes a holder device that holds the shuttle in the first position and a locking device that continuously prevents the shuttle from rotating relative to the casing.

摘要： A braking arrangement includes a torque plate, a torque button, and a sacrificial bushing. The torque button comprises a head portion and a shaft portion, wherein the head portion is configured to extend at least partially into a torque pocket of an end plate of a brake stack and the shaft portion is configured to extend through an aperture disposed in a back leg of the torque plate. The bushing is configured to be removably coupled between the shaft portion of the torque button and the back leg of the torque plate.

摘要： A brake assembly is suitable for use in conjunction with a wheel having a rim rotatably mounted to an axle. The brake assembly includes a rotor configured to rotate about the axis with the rim. The rotor has a first frustoconical rotor surface and either a conductive element or a magnet. The brake assembly further includes a stator fixed in rotation about the axis and configured for selective translation parallel to the axis. The stator has a first frustoconical stator surface proximate to the first frustoconical rotor surface and a conductive element, when the stator has a magnet, or a magnet, when the stator has a conductive element.

摘要： In some examples, an assembly includes a rotor drive key configured to be positioned over a wheel boss defined by a wheel. A drive key body defines a trough configured to receive the wheel boss. An inner surface of the drive key body is configured to establish a conforming contact with an outer profile of the wheel boss and oppose relative motion of the rotor drive key in a radial direction of the wheel. The rotor drive key includes a tab having a tab aperture configured to receive a fastener extending in an axial direction of the wheel and engaging the wheel boss.

摘要： A multi-disk brake system comprises an electrical generator disposed therein. The electrical generator is configured to convert mechanical energy to electrical energy. The mechanical energy may be generated during a braking event of the multi-disk brake system. The electric generator may power various electrical components on the aircraft or store the electrical energy in a capacitor bank. The electric generator may also act as a motor and/or power a landing gear in a motor configuration.
