Title (EN) APPARATUS FOR SHIFTING CENTER OF GRAVITY OF A WORK VEHICLE
(FR) DISPOSITIF POUR LE DEPLACEMENT DU CENTRE DE GRAVITE D"UN VEHICULE DE TRAVAIL
Abstract: front page image
(EN)A work vehicle (10) such as, for example, a tractor (74) or loader (27) has a center of gravity (12), a body (14) and first and second continuous track assemblies (18, 20). In the use of the tractor (74), for example, forwardly locating the center of gravity (12) can increase penetration of a bulldozer (76) on the tractor (74) during bulldozing operations. During ripping operations, penetration of a ripper (78) on the tractor (74) can be increased by rearwardly locating the center of gravity (12). Apparatus (22) is provided for controllably moving the body (14) relative to both of the track assemblies (18, 20). Said apparatus (22) thus controllably shifts the center of gravity (12) of the tractor (74) relative to both of said track assemblies (18, 20) for selectively increasing penetration of the ripper (78) or bulldozer (76) depending upon the operation being performed by said tractor (74).
(FR)Un vehicule de travail tel que, par exemple, un tracteur (74) ou un chargeur (27) possede un centre de gravite (12), un corps (14) et un ensemble d"une premiere et d"une seconde chenille continue (18, 20). Dans l"utilisation d"un tel tracteur (74), la localisation avancee du centre de gravite (12) peut augmenter la penetration d"un bulldozer (76) monte sur le tracteur pendant des operations utilisant le bulldozer. Pendant des operations de defoncage, la penetration d"un outil de defoncage (78) monte sur le tracteur peut etre augmentee par la localisation en arriere du centre de gravite (12). Un dispositif (22) est prevu pour le deplacement controlable du corps (14) par rapport aux deux chenilles (18, 20). Un tel dispositif deplace de maniere controlable le centre de gravite (12) du tracteur (74) par rapport aux deux chenilles (18, 20) pour augmenter selectivement la penetration de l"outil de defoncement (78) ou du bulldozer (76), ceci en fonction de l"operation effectuee par ledit tracteur (74).
