Abstract

L'invention concerne un roue motrice de véhicule capable de diminuer d'au moins de moitié l'énergie motrice, grâce à un nouveau mécanisme de transmission de puissance installé entre un arbre de transmission et un pneu, et utilisée sur des véhicules privés, des camions, des semi-remorques, des engins de chantier, des véhicules utilitaires lourds et des voitures électriques pour permettre une économie d'énergie. Selon cette invention, la puissance de l'arbre de transmission (21a) classique est transmise à un arbre de transmission double (44a) monté sur un arbre creux (40a) d'un plateau fixe. Une roue (44) d'engrenage est placée à une extrémité de l'arbre de transmission double. Un cylindre (48) présentant une roue interne (48a) est fixé à un plateau rotatif (47a) relié au pneu et effectue un mouvement de rotation autour de l'arbre de transmission double. Des arbres (50, 55) sont montés sur des bossages (40b, 40c) du plateau fixe (40) formant une seule pièce avec un corps (20) parallèlement à l'arbre de transmission (21a), des petites roues (53, 54, 58) sont montées rotatives sur ces arbres et la petite roue (58) est positionnée au niveau le plus élevé au-dessus de la surface de roulement et les roues s'engrènent mutuellement. Ainsi, seulement la moitié à un tiers de l'énergie requise dans un système classique d'entraînement direct des pneus est nécessaire pour parcourir la même distance à une même vitesse et parvenir à une économie d'énergie notable. De plus, le nombre d'années restantes avant l'épuisement total du pétrole dans le monde pourra être multiplié par 1,3.
