Abstract: The invention relates to aircraft landing gear comprising: a leg (12) for hinging to a structure of the aircraft so as to be movable between a deployed position and a retracted position, a main brace (15), a secondary brace (20), and an unlocking actuator (30) having a first end coupled to the secondary brace and controllable for causing its links to move out of alignment against the action of the resilient member during retraction or deployment of the landing gear. According to the invention, the unlocking actuator is of the double-acting type and the landing gear includes coupling means (31, 33) for coupling to a second end of the unlocking actuator, which means ensure movement of said second end relative to the leg so that, for a given action, the unlocking actuator tends to break the alignment of the links when the landing gear is in one of its positions and tends to confirm said alignment when the landing gear is in its other position.

Abstract translation: 本发明涉及飞机起落架，其包括：用于铰接到飞行器的结构以便在展开位置和缩回位置之间移动的支腿（12），主支架（15），辅助支架（20） 以及解锁致动器（30），其具有联接到所述辅助支架的第一端，并且可控制地使其连杆在所述起落架的缩回或展开期间抵抗所述弹性构件的作用移动离开对准。 根据本发明，解锁致动器是双作用型的，并且起落架包括联接装置（31,33），用于联接到解锁致动器的第二端，这意味着确保所述第二端相对于腿的运动 使得对于给定的动作，当起落架处于其一个位置时，解锁致动器倾向于破坏连杆的对准，并且当起落架处于其另一位置时倾向于确认所述对准。
