Thrust reverser system electro-mechanical brake manual release mechanism

A thrust reverser system electromagnetic brake assembly, comprising:

• a housing;
• a rotor plate rotationally mounted within the housing;
• an armature mounted against rotation within the housing and disposed proximate the rotor plate, the armature configured to move between (i) an engage position, in which the armature engages the rotor plate to prevent rotation thereof, and (ii) a disengage position, in which the armature does not engage the rotor plate to allow rotation thereof;
• one or more springs disposed within the housing and configured to supply a bias force that biases the armature toward the engaged position;
• an armature coil disposed within the housing, the armature coil configured to be selectively energized, to thereby generate a magnetic force that moves the armature to the disengaged position;
• and
• a manual brake release mechanism disposed proximate the electromechanical brake and configured to selectively move the armature between the engage and disengage position, the manual brake release mechanism including:
• a first release plate configured to selectively rotate in either a first or a second rotational direction in response to an input force, and
• a second release plate coupled to the first release plate and configured to move in either a first or a second translational direction in response to the first release plate rotating in the first or second rotational direction, respectively, to thereby move the armature to the disengage or engage position, respectively.

A thrust reverser system manual brake release mechanism, comprising:

• a first release plate including an exterior side and an interior side;
• at least two grooves formed in the first release plate interior side, the grooves each having a cam surface located at a predetermined angle;
• a second release plate including an exterior side and an interior side, the second release plate interior side positioned opposed to the first release plate interior side;
• at least two grooves formed in the second release plate interior side and substantially aligned with at least two of the grooves in the first release plate, the grooves in the second release plate each having a cam surface located at a predetermined angle;
• at least two balls, each positioned in the aligned grooves;
• a handle coupled to, and extending from, the first release plate to allow manual rotation thereof;
• an alignment mechanism extending at least partially through the first and second release plates;
• a plurality of slots formed on the manual brake alignment mechanism;
• and
• a spring having a first end and a second end, the spring first end coupled to the handle, the spring second end disposed within one of the manual brake alignment mechanism slots.
