摘要： A landing gear (100A, 100B) including an outer cylinder (110) rotatably coupled to a frame of an aircraft (1000) about a trunnion axis of rotation, a shock strut assembly (120) movably coupled to the outer cylinder (110) so as to reciprocate along a longitudinal axis (115) of the outer cylinder, and a shrink mechanism (130A, 130B) including a first shrink link member (140) pivotally coupled to the outer cylinder, a second shrink link member (150) coupling the first shrink link member to the shock strut assembly (120), a crank member (160) pivotally coupled to the outer cylinder (110), a drive member (170) coupling the crank member (160) to a walking beam (210) of a landing gear retract mechanism (200), and a driven member (180) coupling the crank member (160) to the first shrink link member (140).
