An articulating vehicle (10) includes a front axle (21) operatively connected to a front frame (40) and a rear axle (21) is operatively connected to the rear frame (30). A torsional joint (50) has an inner shaft member (51) operatively connected to one of the frames and an outer hollow member (52) operatively connected to the other of the frames. An elastomeric material (53) is positioned between the inner member (51) and outer member (52). The elastic material (53) connects the inner and outer members, whereby the frames may rotate relative to each other along the longitudinal axis as the elastomeric member (53) is compressed and resiliently resists rotation between the frames (30 and 40). A torsional energy absorption suspension is provided for one of the wheels. The suspension includes a torsional joint (50), a single A-frame member (94). A lever arm (95) may also be utilized to vary the preload on the torsional joint (50).
L'invention porte sur un véhicule articulé (10) comprenant un essieu avant (21) raccordé de manière fonctionnelle à un cadre avant (40) et un essieu arrière (21) est raccordé de manière fonctionnelle au cadre arrière (30). Un joint (50) de torsion comporte un élément (51) d'arbre intérieur raccordé de manière fonctionnelle à l'un des cadres. Un matériau (53) élastomère est positionné entre l'élément (51) intérieur et l'élément (52) extérieur de façon à les raccorder. Les cadres peuvent tourner l'un par rapport à l'autre le long de l'axe longitudinal au moment où l'élément élastomère (53) est comprimé et résiste à la rotation entre les cadres (30 et 40). Une suspension à absorption d'énergie en torsion est prévue pour l'une des roues. Cette suspension comprend un joint de torsion (50), un élément (94) unique de cadre A. Un bras (95) de levier peut également être utilisé pour faire varier la précharge sur le joint de torsion (50).
