ELECTRIC BRAKE ACTUATOR MODULE FOR AIRCRAFT

摘要

An electro-mechanical brake assembly (11) comprising a brake disk stack (20) having a center axis and a plurality of electro-mechanical actuators (46) for applying braking pressure to the brake disk stack. The actuators are circumferentially arranged around the center axis (48), and each actuators includes a housing (53), a linearly movable ram (45), a screw (52) for linearly moving the ram, a nut (65) mounted for rotation in the housing and operatively engaged with the screw such that rotation of the nut effects linear movement of the screw for urging the ram into forceful engagement with the brake disk stack, an electric motor (50) for rotating the nut, and an anti-rotation device (82) for preventing rotation of the screw relative to the housing when the nut is rotated to effect linear movement of the screw. The foregoing arrangement provides for greater stroke than prior art actuators without sacrificing durability and performance.
