More Information
Summary:A steering system for amphibious vehicle includes a control connected to road steering means. Ram is conventionally used to assist road steering, but by disconnecting command valves, it becomes a hydraulic master cylinder, driving slave cylinder; and thus marine steering means. Valves and hydraulic reservoir enable the marine steering to be disconnected from road steering. The marine steering means may be center biased by springs. A sensor and control means may synchronize center positions of road and marine steering. The valve and port layout may also achieve this goal. Alternatively, power steering in road mode may be maintained by fitting a master cylinder in parallel or in series with steering means; and may have hydraulic, electro-hydraulic, electric, or magnetic assistance.
