Abstract

The present invention relates to landing gear. The landing gear has a strut (2) having one end pivotally mounted about a first axis (4) suitable for connection to the structure (1) of an aircraft. A lower portion (6) for supporting running gear (10) is pivotally mounted relative to said strut (2) to pivot about a second axis. A collapsible side brace (20) has one end suitable for connection to a first point (27) of the aircraft structure (1) for pivoting about a third axis (29) and a fourth axis (30) providing rotation with two degrees of freedom about said third and fourth axes respectively. The third axis (29) passes through said first point (27) being situated on a line which is not colinear with the first axis but which intersects said first axis at a second point (40). A pivot pin (33) is rotatable about a fifth axis (35), the fifth axis not being colinear with said first (4), third (29) and fourth (30) axes and being situated on a line which passes through said second point (40). Pivot pin (33) is connected firstly via a sixth axis of rotation (32) to the other end (31) of said collapsible side brace (20), and secondly via a crank system (43, 46, 50) to said lower portion (6)…
