<p>An aircraft undercarriage comprising two rocker beams (1, 2) carrying wheels and mounted to pivot on a common pivot (Y1), the undercarriage including a shock-absorber device comprising two connecting rods (5, 6), each coupled to a respective one of the rocker beams, at least one of the connecting rods being telescopic and forming a shock absorber, the two connecting rods also being coupled to a rocker (7) pivotally mounted on a central pivot (8). The common pivot of the rocker beams is secured to the structure of the aircraft and is mounted in a fixed position thereon, while the central pivot of the rocker is movable between a first position in which the rocker beams are in a landing position, and a second position in which the rocker has pulled on the connecting rods to cause the rocker beams to pivot towards a retracted position.</p> |
