Title
(EN) METHOD AND MEANS FOR PROVIDING REAR STEERABILITY IN A TRAILER ASSEMBLY
(FR) PROCEDE ET MOYEN DE GUIDAGE DU TRAIN ARRIERE DANS UN ENSEMBLE A REMORQUE
Abstract
(EN)
A tractor trailer or other truck (11) or vehicle is equipped with an auxiliary rear steering arrangement in which one (35) or both sets of dual wheels (33, 35) are equipped for vertical movement and/or a pivoted turning movement plus locking at various angles of turning. In operation, the weight of the truck or trailer (15) and any load on the truck is removed from the dual wheel axle equipped for turning by either extending the other dual wheel (33, 191, 195) to lift the trailer or truck body (31) or by lifting the turning equipped axle assembly (51, 301, 347). Such axle assembly (51, 301, 347) is then turned and the weight of the truck returned to the turned axle and removed from the adjacent unturned dual axle while the truck is moved causing the trailer to move partly to the side. The wheels are then returned to the starting or road condition.
(FR)
Une semi-remorque ou autre camion (11) ou véhicule est équipé d'un agencement auxiliaire de direction du train arrière dans lequel un jeu (35) ou deux jeux de roues jumelles (33, 35) sont équipées pour pouvoir effectuer un mouvement vertical et/ou un mouvement tournant pivotant puis verrouillage avec différents angles de braquage. En fonctionnement, le poids du camion ou de la remorque (15) et toute charge transportée par le camion sont délestés de l'essieu à roues jumelées équipé pour braquer soit par extension de l'ensemble des roues jumelées (33, 191, 195) pour soulever le corps (31) de la remorque ou du camion (31) soit en soulevant l'essieu équipé tournant (51, 301, 347). Un tel ensemble d'essieu (51, 301, 347) peut alors braquer et le poids du camion revient sur l'essieu braqué et est délesté du double essieu adjacent non braqué pendant le mouvement du camion provoquant un mouvement partiel de côté de la remorque. Les roues peuvent ensuite revenir à leur état initial, à savoir sur la chaussée.
