Abstract: front page image
(EN)A multi-purpose four-wheel drive vehicle is disclosed having four-wheel steering. A hitch (68) is slung below the vehicle body between the front and rear wheels or forward of the front wheels. By slinging the hitch in this manner the force applied to the rear wheels and also the front wheels, to move the vehicle forward, is given a component towards the ground so that the heavier the load towed and the greater traction required to pull the load the greater the vertical force applied to the wheels thereby increasing traction between these wheels and the ground. The multi-purpose vehicle incorporates a relatively high ground clearance which is achieved by employing four vertical axles and wheels situated at the four comers of a main frame body of the vehicle. The vertical axles are situated in respective spaced-apart leg post members (54a to 54d), each leg post member being rigidly interconnected by two spaced-apart longitudinally extending frame members (50, 52) and two spaced-apart transversely extending frame members (56, 58). At least three (50, 52, 56) of the frame members are of torsionally resilient construction. The vehicle incorporates a belt or chain and sprocket transmission for driving the vehicle which can also be used as an amphibious transporter.
(FR)Vehicule a usages multiples a traction et direction sur les quatre roues. Un tirant (68) est suspendu sous le corps du vehicule entre les roues avant et arriere ou a l"avant des roues avant. En suspendant ainsi le tirant on imprime a la force appliquee aux roues arriere ainsi qu"aux roues avant, pour deplacer le vehicule vers l"avant, une composante vers le sol de maniere que la force verticale appliquee aux roues soit d"autant plus grande que la traction augmente. La traction est a son tour d"autant plus grande que le poids remorque est plus important. Il en resulte que la traction entre les roues et la terre est augmentee. Le vehicule a une garde au sol relativement elevee. Ceci est obtenu par quatre essieux verticaux avec les roues situees aux quatre coins d"un chassis principal du corps du vehicule. Les essieux (54a a 54d) se situent respectivement dans des jambes formant des colonnes espacees. Chaque jambe en colonne est interconnectee de maniere rigide par deux elements de cadre (50, 52) longitudinaux et espaces et par deux tels elements transversaux (56, 58). Au moins trois (50, 52, 56) des elements du cadre ont une construction permettant leur deformation en torsion. Le vehicule comprend une transmission a courroie ou a chaine. Le vehicule peut aussi etre utilise comme transporteur amphibie.
