摘要： The invention relates to a latch device, in particular for latching an airplane landing gear or an airplane landing gear hatch, the device comprising a box containing a set of hinged elements mounted to pivot about respective parallel axes, said assembly including at least one hook and a locking lever connected to said hook by associated elastically deformable return means, said hook being capable of being unlocked by acting on said locking lever either via first actuator means in a normal mode of operation, or via a second actuator means in an emergency mode of operation when said first actuator means fails to unlock the hook. In accordance with the invention, the first actuator means associated with the normal mode of operation is a low power electromechanical actuator under independent electrical control.

In accordance with the invention, the second actuator device associated with the emergency mode of operation is an electromechanical actuator under independent electrical control, said actuator comprising two electric motors associated in irreversible manner with a common differential gear train, having an outlet shaft controlling the pivoting of an emergency unlocking lever co-operating with the locking lever used in normal operation.
摘要翻译：一种闩锁装置，特别是用于锁定飞机起落架或飞机起落架舱口的装置，该装置包括一个盒子，该箱子包含安装成围绕各自的平行轴线枢转的一组铰链元件，所述组件包括至少一个钩和连接的锁定杆通过相关的可弹性变形的返回装置到所述钩子，所述钩子能够通过在正常操作模式下通过第一致动器装置作用在所述锁定杆上或者当紧急操作模式时通过第二致动器装置被解锁，当所述钩第一执行器装置无法解锁挂钩。根据本发明，与紧急操作模式相关联的第二致动器装置是在独立电气控制下的机电致动器，所述致动器包括两个不可逆转地与普通差速齿轮系相联的电动马达，其具有控制枢转与正常操作中使用的锁定杆配合的紧急解锁杆。
