20120318909 | LANDING GEAR - Aircraft landing gear including an axle pivotally connected to a bogie beam and a locking device. The locking couples the axle to the bogie beam, and has a movable member and a follower. The movable member is movable between first and second configurations. Movement of the movable member towards the second configuration causes corresponding movement of the follower so as to transfer a steering force to the axle through the follower which causes the axle to rotate in a first direction. With the movable member in the first configuration, the follower is in a first configuration that inhibits the movable member being moved by an external force applied to the axle. With the movable member in the second configuration, the follower in a second configuration that permits the movable member to be moved by an external force applied to the axle. | 12-20-2012 |
