Hydrostatic Steering Designed for Large Off-Highway Vehicles 720803

Simplified power steering control of large off-highway vehicles still remains a formidable problem for steering system designers. Several hydraulic power steering mechanisms presently prevail with varying envelope and performance features compromised for off-highway application.
This paper describes the first low-cost positive displacement-type hydrostatic steering unit especially designed for the large off-highway vehicle industry. The basic features of the HGB hydrostatic steering system are discussed relative to set goals in each major design area. It is shown that the HGB Hydraguide meets the general requirements for a simplified high-flow hydrostatic steering unit adaptive to the off-road construction and earthmoving machine.
