摘要： An emergency stop for a brake device for a motor includes a blocking device, a spring, and an inhibiting material. The blocking device is movable between a first position, at which it allows rotation of the drive shaft, and a second position, at which it at least substantially stops rotation of a drive shaft of the motor. The spring is housed at least partially within the housing, and urges the blocking device toward the first position. The inhibiting material at least partially surrounds the blocking device and/or the spring, and has a melting point that is at least substantially known. The inhibiting material at least substantially prevents movement of the blocking device from the first to the second position when a temperature is below the melting point, and allows movement of the blocking device from the first to the second position when the temperature is above the melting point.

摘要： An electromechanical actuator is provided for converting rotary action into linear action, and includes an electric motor, a cable yoke, an output shaft, and a pair of cables. The electric motor is adapted to be selectively energized and is configured, upon being energized to generate a drive torque. The cable yoke is coupled to receive the drive torque and is configured, upon receipt thereof, to rotate about a rotational axis. The output shaft is coupled to receive a drive force and is configured, upon receipt thereof, to translate along a linear axis that is disposed at least substantially perpendicular to the rotational axis. Each cable is wound, in pretension, on a portion of the cable yoke and around a portion of the output shaft. The pair of cables is configured, upon rotation of the cable yoke, to supply the drive force to the output shaft.

摘要： A fluid-powered thrust reverser actuation speed control system and method are provided. A drive fluid is supplied to a fluid-powered drive mechanism that is coupled to a thrust reverser movable component to thereby move the thrust reverser movable component at a first movement speed. A determination is made as to when the thrust reverser movable component attains a predetermined position. In response to the thrust reverser movable component attaining the predetermined position, the drive fluid supplied to the fluid-powered drive mechanism is controlled to thereby move the thrust reverser movable component at a second movement speed that is less than the first movement speed.

摘要： In some examples, a system includes a brake rotor, a brake armature configured to engage with the brake rotor to substantially fix a rotational position of the brake rotor relative to the brake armature, and a mechanism mechanically coupled to the brake armature. The brake armature may be configured to rotate in a first rotational direction and a second rotational direction substantially opposite the first rotational direction. The mechanism may be configured to maintain the brake armature in a fixed rotational position when a torque applied to the brake armature in a second rotational direction is less than or equal to a threshold torque value. The mechanism also may be configured to permit rotation of the brake armature in the second rotational direction when torque on the brake armature in the second rotational direction exceeds the threshold torque value.
