A very large truck comprising a frame including spaced frame members (10, 11; 41, 42; 61, 62; 67, 68) carrying a forward frame means (14, 53, 63) for supporting at least two front wheels (W f) via suspension means (92), said frame means carrying hubs (12, 13; 45, 46; 81; 82) each supporting a pair of rear wheels (W r) one on either side of each hub, means (24, 25; 47; 73, 74) for pivotally mounting a substantially rigid load supporting body (B), means (B; 56, 57; 89) for maintaining the transverse spacing between the rear wheel pairs, said frame members being constructed to provide resistance to torsional movement of said rear wheels due to braking and traction forces while providing compliance for limited rotation of said rear wheel pairs about a longitudinal axis of each frame member to allow side tilting of the rear wheel pairs as the truck passes over uneven terrain.
La présente invention se rapporte à un très gros camion, qui comprend une structure composée d'éléments de structure espacés (10, 11; 41, 42; 61, 62; 67, 68) portant une organe de structure antérieure (14, 53, 63) destiné à soutenir au moins deux roues avant (Wf) par l'intermédiaire d'organes de suspension (92). Les éléments de structure comportent de moyeux (12, 13; 45, 46; 81, 82) portant chacun une paire de roues arrière (Wr) placées chacune de part et d'autre de chaque moyeu des organes (24, 25; 47; 73, 74)permettant le montage pivotant d'un corps de support de charge sensiblement rigide (B), ainsi que des organes (B; 56, 57; 89) servant à maintenir l'espacement transversal entre les paires de roues arrière. Les éléments de structure sont construits de façon à assurer une résistance aux mouvements de torsion des roues arrière dus aux forces de freinage et de traction, tout en assurant l'élasticité pour une rotation limitée des paires de roues arrière autour d'un axe longitudinal de chaque élément de structure, permettant ainsi une inclinaison latérale des paires de roues arrière lors du passage du camion sur un terrain accidenté.
