Abstract

Le véhicule décrit, qui est du type tout-terrain ou aquatique, comprend un châssis (60) destiné à supporter une charge, ainsi que des unités de roues ou de flotteurs antérieure et postérieure (61, 62) reliées pivotantes aux extrémités pivotantes du châssis, de façon à pivoter autour d'axes coaxiaux ou parallèles correspondants. Une structure stabilisatrice (67, 68, 69) relie entre elles les unités respectives (61, 62), de sorte qu'un mouvement pivotant de l'une des unités entraîne un mouvement angulaire opposé et d'ampleur égale de l'autre unité. La structure stabilisatrice contient un élément de torsion relié au châssis de façon à commander la position de celui-ci.
