  • LANDING GEAR SHRINK LINK MECHANISM
    Publication number: 20230322369
    Abstract: A landing gear including an outer cylinder, a shock strut assembly, and a passive shrink mechanism. The outer cylinder is coupled to a frame of an aircraft about a trunnion axis of rotation. The shock strut assembly is coupled to the outer cylinder for reciprocation along a longitudinal axis of the outer cylinder. The passive shrink mechanism includes: a first shrink link member coupled to the outer cylinder, a second shrink link member coupling the first shrink link member to the shock strut assembly, a crank member coupled to the outer cylinder, a first connecting link coupling the crank member to a walking beam of a landing gear retract mechanism, and a second connecting link coupling the crank member to the first shrink link member. The passive shrink mechanism is passively extended and shortened through actuation of the landing gear retract mechanism with deployment and retraction of the landing gear.

  • Landing gear shrink link mechanism
    Patent number: 11708151
    Abstract: A shrink mechanism for use with a landing gear of an aircraft. The landing gear includes an outer cylinder rotatably coupled to a frame of an aircraft about a trunnion axis of rotation and a shock strut assembly movably coupled to the outer cylinder so as to reciprocate along a longitudinal axis of the outer cylinder. The shrink mechanism incudes a first shrink link member pivotally coupled to the 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 the crank member to a walking beam of a landing gear retract mechanism, and a driven member coupling the crank member to the first shrink link member.
