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.
