Abstract

La présente invention porte sur des véhicules à moteur, et, de façon plus spécifique, sur des véhicules à cinq roues pour manœuvrer dans des zones d'espace limité. Le cadre de châssis de véhicule à moteur a une roue d'entraînement et de direction centrale et a une aptitude à changer la direction de conduite de 360° sur place. Ceci produit un véhicule plus simple pour fonctionner dans des zones avec un espace limité, telles qu'une zone d'intérieur urbain (centre ville) et dans des zones de stockage telles que des entrepôts.
