An aircraft brake assembly, wherein the actuator portion of the brake assembly is no longer provided as part of the brake assembly but instead as part of the aircraft landing gear. Accordingly, the actuator portion or individual actuators assemblies are designated as Line Replacement Units (LRUs), which are replaceable independently of other brake components, e.g., the torque tube and heat sink, which then comprise the brake assembly designated as a separate LRU. This new arrangement is particularly suited to electro-mechanically actuated brakes, where actuator maintenance intervals will typically be more closely related to landing gear maintenance intervals than to brake maintenance (i.e., hydraulic actuator and/or heat sink maintenance). The invention also provides for more effective and desirable mounting of one or more electro-mechanical actuators wherein reactionary loads are transferred in compression as opposed to in tension through mounting bolts or other removable fasteners.
A wheel and brake assembly comprising a wheel support, a wheel rotatably mounted on the wheel support, a torque transfer member coupled to the wheel support for transfer of torque from the brake disk stack to the wheel support during braking, a brake disk stack supported on the torque transfer member, and an actuator assembly mounted on the wheel support for applying braking force to the brake disk stack, and wherein the brake disk stack and torque transfer member are removable from the wheel support without removal of the actuator assembly, the actuator assembly includes a plurality of actuator modules individually removably mounted to the wheel support, each actuator module includes a motor and a ram both carried by a respective housing, and the wheel support has at least one flange thereon to which the actuator modules are mounted.
