Actuation Device for Moving a Movable Cowling of a Thrust-Reverser

摘要

The invention relates to an actuation device (1) for moving the movable cowling of a thrust reverser, comprising: an actuator (7) with a first member (12) such as a screw, and a second member (14) such as a nut, wherein the first and second members are capable of engaging such that the rotation of the first member results in a translation of the second member, a locking device (33) including a locking part (34) movable between a locked position for preventing to the rotation of the first member and an unlocked position for enabling the rotation of the first member, and a lock inhibiting device (42) comprising a recess (46) and a ball (47) movable in the recess between a stowed position, in which the ball enables the movement of the locking part, and an inhibition position in which the ball prevents the locking part from returning into the locked position.

主权项

1. An actuating device for moving a movable cowl of a thrust reverser, comprising:
an actuator comprising a first element and a second element mounted movable in translation relative to the first element, one of the first element and the second element being a screw, and the other being a nut suitable for cooperating with the screw, so that a rotation of the first element relative to the second element causes a translation of the second element relative to the first element, a locking device comprising a locking part movable between a locked position in which the locking part prevents rotation of the first element, and an unlocked position in which the locking part allows rotation of the first element, and a lock inhibitor device comprising a housing and a ball movable in the housing between a stowed position in which the ball allows a motion of the locking part between the locked position and the unlocked position, and an inhibiting position in which the ball protrudes out of the housing to prevent the return of the locking part to the locked position.
