Abstract
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.
Claims22
A landing gear for an aircraft, the landing gear including an axle pivotally connected to a bogie beam and a locking device, the locking device being arranged to couple the axle to the bogie beam, the locking device including a movable member and a follower, the movable member being arranged to be moved by an actuator between first and second configurations, the locking device being arranged such that movement of the movable member from the first configuration to 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, wherein, with the movable member in the first configuration, the locking device is arranged with the follower in a locking configuration that inhibits the movable member being moved by an external force applied to the axle and, with the movable member in the second configuration, the locking device is arranged with the follower in a passive configuration that permits the movable member to be moved by an external force applied to the axle.
A landing gear for an aircraft, the landing gear including an axle pivotally connected to a bogie beam and locking means, the locking means being arranged to couple the axle to the bogie beam, the locking means including movable means and follower means, the movable means being arranged to be moved by actuator means between first and second configurations, the locking means being arranged such that movement of the movable means from the first configuration to the second configuration causes corresponding movement of the follower means so as to transfer a steering force to the axle, through the follower means, which causes the axle to rotate in a first direction, wherein, with the movable means in the first configuration, the locking means is arranged with the follower means in a locking configuration that inhibits the movable means being moved by an external force applied to the axle and, with the movable means in the second configuration, the locking means is arranged with the follower means in a passive configuration that permits the movable means to be moved by an external force applied to the axle.
An aircraft landing gear steering system comprising:
- a landing gear bogie beam;
- a landing gear axle pivotally connected to the bogie beam;
- a lock connecting the axle to the bogie beam, the lock comprising a movable member and a follower;
- and
- an actuator configured to move the movable member between a first position and a second position;
- wherein movement of the movable member from the first position to the second position applies a first steering force, through the follower and to the axle, to rotate the axle in a first direction;
- and
- wherein, when the movable member is in the first position, the follower is positioned relative to the movable member such that an external force applied to the axle does not generate a substantial force to move the movable member and, when the movable member is in the second position, the follower is positioned relative to the movable member such that the external force applied to the axle generates a substantial force against the first steering force.
A landing gear for an aircraft, the landing gear including an axle pivotally connected to a bogie beam and a locking device, the locking device being arranged to couple the axle to the bogie beam, the locking device including a movable member and a follower, the movable member being arranged to be moved by an actuator between first and second configurations, the locking device being arranged such that movement of the movable member from the first configuration to 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, wherein, with the movable member in the first configuration, the locking device is arranged with the follower in a locking configuration that inhibits the movable member being moved by an external force applied to the axle so that the axle is positionally locked with respect to the bogie beam and, with the movable member in the second configuration, the locking device is arranged with the follower in a passive configuration that permits the movable member to be moved by an external force applied to the axle.
