Abstract: A load limiter has a first disk for translating a first torque from an input and a second disk for translating a second torque from an output. Each of the first disk and the second disk has a ramp in which a torque transmitter, such as a ball is disposed. A first conical brake surface and a second conical brake surface disposed on the first disk or the second disk interact if the first torque and/or the second torque cause relative rotation between the first disk and the second disk.

Abstract: A no-back assembly includes a first disc coupled to a first shaft and arranged radially outward of the first shaft. Also included is a first brake arranged radially outward of the first disc. Further included is a spring adjacent the first brake. Yet further included is a second disc coupled to a second shaft and arranged radially outward of the second shaft. Also included is a second brake arranged radially outward of the second disc. Further included is at least one pin operatively coupling the first brake and the second brake to a housing of the no-back assembly, a gain reduction spring disposed within a recess of the housing, and a piston disposed in contact with the gain reduction spring and a first side of the pin, wherein the gain reduction spring biases the piston against the first side of pin, wherein the pin is biased against the housing.

Abstract: A device and method for determining whether a no-back device is functioning properly includes a no-back device coupling an input shaft and an output shaft. A no-back output gear is coupled to the output shaft, and a reaction gear is operably coupled to the no-back output gear. A check device includes a rotatable drive feature having a first end accessible for rotation and a second end engaged with the reaction gear. The functionality of the no-back device is evaluated by applying a rotational torque to the drive feature.

Abstract: Disclosed is a cone brake no-back for use with an actuation system. The actuation system may be an aircraft actuation system, for example. The no-back may include cone brakes capable of preventing undesired displacement of an aircraft surface (such as a flap, a leading edge, or a trailing edge of a wing) in the event that an actuator input becomes disconnected or is otherwise insufficient to oppose the load created by the aircraft surface.

Abstract: A disclosed sensor assembly for detecting movement and a position of a wing flap includes a sensing device that generates a signal corresponding to a position of the flap. The sensor assembly includes a linkage that is attached to the movable flap for mechanically communicating movement of the flap to the sensing device. The linkage includes a first pivot shaft mounted to the flap that is disposed about a first axis and a second pivot shaft attached to the first pivot shaft for movement about a second axis transverse to the first axis.

Abstract: An asymmetry brake includes a housing, a shaft, a pilot brake, a primary brake, and a ball ramp assembly. The shaft of the asymmetry brake is rotatable relative to the housing about an axis of rotation. The primary brake is movably connected with the shaft. The pilot brake is configured to selectively engage the housing to generate a triggering torque. The triggering torque is transferred through the ball ramp assembly to the primary brake, which in response engages the housing to generate a braking torque on the shaft. The disposition of the ball ramp assembly between the pilot brake and the primary brake allows the ball ramp assembly to return to an operative non-separated condition when the pilot brake is disengaged from the housing. The return of the ball ramp assembly to the operative non-separated condition allows the primary brake to disengage from the housing which releases the shaft to rotate.

Abstract: A brake position sensor unit includes a unitary brake shaft that transmits braking torque to a article to be slowed, connects directly to a brake unit, connects to a resolver and has a plurality of planetary gears rotating thereabout to activate a sensor when the brake unit is set.

Abstract: A feedback torque limiter device for an actuator having an input shaft, output shaft and gear reduction for transmitting torque from the input shaft to the output shaft comprises an output torque sensor, and input torque limiter and a feedback mechanism. The output torque sensor senses actuator output torque downstream from an actuator gear reduction. The input torque limiter grounds additional torque from the input shaft when engaged. The feedback mechanism engages the input torque limiter when the output torque sensed by the output torque sensor reaches a predetermined value.
