Abstract
An articulated vehicle is disclosed which includes first and second vehicle sections interconnected by an articulating linkage. The articulating linkage includes a universal joint and a cooperating pantograph linkage. The universal joint and the pantograph linkage define a vertically extending steering axis about which the vehicle sections are relatively pivoted to enable steering. The pantograph linkage comprises a first link bar pivoted to one vehicle section in substantial alignment with the steering axis and second and third link bars connected between respective end portions of the first link bar and connecting locations on the other vehicle section. A steering actuator is connected between the first link bar and the associated vehicle section and is operated to provide forces for steering the vehicle. The pantograph linkage and universal joint cooperate to enable relative vehicle section oscillations without significant changes in the vehicle steering geometry while isolating the steering actuator from direct application of large magnitude forces which might otherwise be applied to it by relative oscillations of the vehicle sections.
