The disclosure relates to a landing gear shrink link mechanism. The landing gear including an outer cylinder rotatably coupled to a frame of an aircraft about a trunnion axis of rotation, a shock strut assembly movably coupled to the outer cylinder so as to reciprocate along a longitudinal axis of the outer, cylinder, and a shrink mechanism including a first shrink link member pivotally coupled tothe outer cylinder, a second shrink link member coupling the first shrink link member to the shock strut assembly, a crank member pivotally coupled to the outer cylinder, a drive member coupling thecrank member to a walking beam (a.k.a. retract actuator beam) of a landing gear retract mechanism, and a driven member coupling the crank member to the first shrink link member. 本公开涉及一种起落架收缩连杆机构。一种起落架包括：外筒，围绕耳轴旋转轴线可旋转地耦接到飞机的框架；减震支柱组件，可移动地耦接到外筒以便沿着外筒的纵向轴线往复运动；以及收缩机构，该收缩机构包括：第一收缩连杆构件，枢转地耦接到外筒；第二收缩连杆构件，将第一收缩连杆构件耦接到减震支柱组件；曲柄构件，枢转地耦接到外筒；从动构件，将曲柄构件耦接到起落架收回机构的步进梁(又称作收回致动器梁)；以及从动构件，将曲柄构件耦接到第一收缩连杆构件。
