Motor-vehicle having at least a rear driving wheel and two front rolling and steering wheels connected to each other by a linkage mechanism (15; 15bis) provided with a suspension system (19) that comprises at least a pair of shock-absorbing struts (60A, 60B; 60C, 60D) and rocking levers (61A, 61B; 61C, 61D) associated therewith. An interconnecting latticework (14) extending along the median plane (PM) of the vehicle supports the axis (A) of the pins (50, 51; 57, 58) of the rocking levers (61A, 61B; 61C, 61D) so that it is caused to lie on the same median plane and parallel to the axes (X, Y) of the fulcrum pins (52, 53, 54) of the cross bars (20, 21, 22, 23) of the linkage mechanism (15). The rolling speed of the front wheels can be varied.
L'invention concerne un véhicule automobile doté d'au moins une roue arrière motrice et de deux roues directrices et roulantes avant, connectées l'une à l'autre par un mécanisme de liaison (15 et 15bis) doté d'un système de suspension (19) qui comporte au moins une paire d'amortisseurs absorbant les chocs (60A, 60B; 60C, 60D) et des balanciers (61A, 61B; 61C, 61D) associés. Un réseau interconnecté (14) orienté le long du plan médian (PM) du véhicule supporte l'axe (A) des tiges (50, 51; 57, 58) des balanciers (61A, 61B; 61C, 61D), de manière à ce qu'il soit forcé de rester sur le même plan médian et parallèle aux axes (X, Y) des tiges pivot (52, 53, 54) des barres de stabilisation (20, 21, 22, 23) du système de liaison (15). La vitesse de roulement des roues avant peut varier.
