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 electromechanical 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 tube, and an actuator assembly mounted on the wheel support for applying braking force to the brake disk stack, wherein the brake disk stack and torque transfer member are removable from the wheel support without removal of the actuator assembly.
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 tube, and an actuator assembly mounted on the wheel support for applying braking force to the brake disk stack, wherein the actuator includes a plurality of actuator modules individually removably mounted to the wheel support, and the actuator modules have at least one mounting flange abutting axially outwardly facing mounting surface on the wheel support.
