Abstract

CE VEHICULE COMPREND UN CHASSIS CLASSIQUE 2 EQUIPE DE QUATRE ROUES, PAR EXEMPLE DEUX ROUES AVANT DIRECTRICES 3 ET DEUX ROUES ARRIERE MOTRICES. IL COMPREND EN OUTRE UNE ROUE DIRECTRICE SUPPLEMENTAIRE 6 ORIENTABLE AU MOYEN D'UN MECANISME DE DIRECTION 10 A COMMANDE HYDRAULIQUE, DE TELLE FACON QUE L'ON PUISSE DONNER A LA ROUE 6 UN GRAND ANGLE DE BRAQUAGE DE PART ET D'AUTRE D'UNE POSITION MEDIANE LONGITUDINALE. LA ROUE 6 EST MONTEE VERTICALEMENT MOBILE PAR RAPPORT AU CHASSIS 2. DURANT LES PHASES DE TRAVAIL, PENDANT LESQUELLES LE VEHICULE EVOLUE A BASSE VITESSE, LA ROUE 6 EST PLACEE EN POSITION BASSE EN CONTACT AVEC LE SOL ET LES DEUX ROUES DIRECTRICES AVANT 6 SONT RELEVEES AU-DESSUS DU SOL PAR UN DISPOSITIF DE LEVAGE COMPRIMANT LA SUSPENSION DES ROUES AVANT 3, DE TELLE SORTE QUE LE VEHICULE ROULE ALORS SUR TROIS ROUES ET PRESENTE UNE GRANDE MANOEUVRABILITE. EN DEHORS DES PHASES DE TRAVAIL, LA ROUE 6 EST PLACEE EN POSITION HAUTE AU-DESSUS DU SOL, ET LE VEHICULE PEUT ALORS ROULER A UNE VITESSE RELATIVEMENT ELEVEE SUR SES QUATRES ROUES, TOUT EN PRESENTANT UNE BONNE STABILITE ET UNE BONNE TENUE DE ROUTE.THIS VEHICLE INCLUDES A CLASSIC 2 CHASSIS EQUIPPED WITH FOUR WHEELS, FOR EXAMPLE TWO FRONT STEERING WHEELS 3 AND TWO REAR DRIVE WHEELS. IT FURTHER INCLUDES AN ADDITIONAL STEERING WHEEL 6 ORIENTABLE BY MEANS OF A HYDRAULICALLY CONTROLLED STEERING MECHANISM 10, SO THAT WHEEL 6 CAN BE GIVEN A WIDE STEERING ANGLE on either side of a LONGITUDINAL MIDDLE POSITION. WHEEL 6 IS MOUNTED VERTICALLY MOVABLE WITH RESPECT TO CHASSIS 2. DURING THE WORK PHASES, WHEN THE VEHICLE IS MOVING AT LOW SPEED, WHEEL 6 IS PLACED IN LOW POSITION IN CONTACT WITH THE GROUND AND THE TWO FRONT STEERING WHEELS 6 ARE UP ABOVE THE GROUND BY A LIFTING DEVICE COMPRESSING THE SUSPENSION OF THE FRONT WHEELS 3, SO THAT THE VEHICLE THEN ROLLS ON THREE WHEELS AND HAS GREAT MANEUVERABILITY. OUTSIDE OF THE WORKING PHASES, WHEEL 6 IS PLACED IN A HIGH POSITION ABOVE THE GROUND, AND THE VEHICLE CAN THEN RUN AT A RELATIVELY HIGH SPEED ON ITS FOUR WHEELS, WHILE PRESENTING GOOD STABILITY AND HANDLING.
