Ce système de suspension comprend: un bras de suspension principal (14) pivotant par rapport à la coque du véhicule à l'une de ses extrémités (20) et comportant à l'extrémité opposée une roue de route montée rotative (12); un organe de mise en mouvement (30) fixé en position opérationnelle audit bras de suspension principal pivotant, pour permettre audit bras et à ladite roue de route de se replier par rapport à la coque du véhicule; un lien de suspension supérieur (120) relié en position opérationnelle et pivotante à l'extrémité du bras de suspension principal portant la roue de route. Ce lien de suspension supérieur comporte en position intermédiaire entre ses extrémités un joint pivotant (60) et ledit lien pivote sur la coque du véhicule au niveau d'un axe (52) distant dudit joint pivotant, et ledit lien de suspension supérieur peut s'engrener en position opérationnelle avec un organe de verrouillage de position de suspension (122, 130, 132, 136, 138) à la fois en position abaissée et en position repliée.
