Abstract: A self-propelled articulated vehicle having two vehicle modules pivotally attached at their ends. Steering of the vehicle is obtained through hydraulic steering components attached between the first and second vehicle modules and pivotally attached at a common end. A single load container is carried across the two vehicle modules at pivotal support mountings, with one of the support mountings cooperating with a linear track device to displace the load container a desired direction and distance when the articulated vehicle is steered. Utilization of independent power drive for each of the two vehicle modules increases the maneuverability of the overall articulated vehicle and minimizes the miring down of the vehicle in slick, muddy, or staggered terrain. Through elimination of conventional steering techniques, increased power and lower fuel consumption is obtained through such an articulated steering technique.

Abstract: A steering system for articulated vehicles having two or more pivotally connected vehicle modules. The invention provides for such a vehicle a dual hydraulic power steering system cooperating with a plurality of telescoping hydraulic cylinders to initiate steering about the pivot point connecting the two or more vehicle modules. Auxiliary, emergency, and back-up steering capabilities are imparted through the use of independently operated double-acting cylinders on both sides of the vehicle pivot attachment, with one hydraulic power system supplementing or replacing the other in case of failure. A series of pumps, accumulators, reservoirs, and other associated hydraulic elements cooperate with the synchronized valve metering construction to accomplish steering of the vehicle.
