Abstract

Un véhicule pour utilisation terrestre est équipé de trois organes de support (3, 4) disposés à distance pour le mouvement vers l'avant. Deux (3) de ces organes de support sont déplaçables simultanément à l'aide d'un dispositif commun de braquage (12, 13, 14) et sont chacun disposés de manière pivotante sur un bras de support (5) étendu dans la partie avant du véhicule. Le troisième organe de support (4) est du type traditionnel et chaque pivot (9) étendu correspondant des deux organes de support (3) est situé dans un plan commun qui intersecte le plan contenant les deux surfaces de contact de support du véhicule et les points de support, chaque axe de pivotement (16) étendu décrivant un angle d'inclinaison vers l'arrière par rapport au plan vertical au travers de l'axe longitudinal du véhicule. Les points d'intersection (19) de chaque axe de pivotement (16) avec le plan horizontal de support sont situés vers l'extérieur perpendiculairement à l'axe longitudinal du véhicule et latéralement et vers l'extérieur depuis chacun des points de contact, l'agencement étant tel que lorsque le véhicule décrit un chemin courbe, le châssis du véhicule est soumis à une action de "pendule" dans le sens du virage. Cette action de "pendule" provoque un mouvement différent relatif tout en tournant l'organe de support du véhicule disposé dans la partie interne de la courbe, lequel se déplace dans une direction vers l'avant, l'organe de support disposé dans la partie externe de la courbe se trouvant dans une position plus rentrée par rapport au mouvement vers l'avant et vice versa.
