Abstract
An element (14) of a swivelling aircraft landing gear, such as an element of the swivelling, rear or tail gear of a wide-body aircraft, equipped with a swivelling, front or nose gear and a non-swivelling, underwing gear, has a swivelling truck (16) carrying a swivelling, front axle (20) and a swivelling, rear axle (22). The orientation of each of these axles is respectively ensured by two linkages (44-49), which are independent of one another and connected to a non-rotary, fixed support (30) carrying the truck (16), in such a way that the axes (Y1, Y2) of the front (20) and rear (22) axles and the axis of the truck (16) intersect at the instantaneous rotation center of the aircraft.
