An aircraft landing gear includes a leg having a strut receiving a telescopic rod to slide on a sliding axis, the strut being hinged to an aircraft structure and being capable of pivoting about a pivot axis that is highly offset from the sliding axis. The landing gear further includes a connection structure essentially comprising two panels connecting two axially separate points of the strut to a common axis structure extending along the strut pivot axis. In the gear-down position, the panels are one above the other, the top panel being connected to the strut via a high attachment which is rigid in twisting, while the bottom panel is connected to the strut via a low attachment which tolerates twisting, thereby enabling the strut to warp to some extent when the aircraft is turning while taxiing.
An aircraft landing gear comprising a leg (11) constituted by a strut (12) in which a telescopic shock-absorber rod (13) slides along a sliding axis (Z), the free end of the rod being hinged to a rocker beam (14) carrying a wheel set having multiple axles, said strut being hinged to a structure of the aircraft and being capable of being pivoted by an associated connection structure about a substantially horizontal axis (X) that is highly offset from the sliding axis (Z) of the telescopic rod (13) which is vertical in the gear-down position, wherein the connection structure (100) is essentially constituted by two panels (101, 102) connecting two axially separated points of the strut (12) to a common axis structure (103) extending along the pivot axis (X) of said strut, in such a manner that in the gear-down position said panels are disposed one above the other, with a top panel (101) which is connected to the strut (12) via a high attachment (105) which is rigid in twisting, and with a bottom panel (102) which is connected to the strut (12) via a low attachment (106) which tolerates twisting, thereby allowing the strut (12) to warp to some extent when the aircraft is turning while taxiing.
