某型飞机起落架双位插销式下位锁设计

The Design of the Landing-Gear System Lower Lock With Two Locations for Thumb Lock of a Aircraft

某型飞机起落架采用双位插销式下位锁,该下位锁由两个锁销、两个锁作动筒、壳体及导向挡块等零部件组成,沿起落架支柱轴线对称布置。该双位插销式下位锁不仅能承受航向力及侧向力,还能承受地面传递给起落架的扭矩。

The landing gear of a certain type of aircraft is composed of two lock pin,two locking cylinder,shell and guide block,which is symmetrical arranged along the axis of the landing gear. The two position latch type lower position lock not only can bear the directional force and lateral force,but also can bear the torque transmitted from the ground to the landing gear.
