ABSTRACT:
Road and marine steering means in an amphibious vehicle are linked so that the ratio between them is variable. In a first embodiment, an arm connects a lever to a steering rack. A cable operates the marine steering means. The lever pivots about a pin, which may be moved along a slot by the motor and gearbox driving screw shaft. At pin position A, full road steering travel x is achieved with minimal marine steering travel. At pin position B, road and marine steering have equal travel x′; and at position C, full marine steering travel z is achieved with minimal road steering travel y. In a further embodiment, a lever arm fixed to steering rack casing has a cam profile constraining pin. Full marine steering travel z of the cable is achieved over rack travel y. The steering wheel controls both road and marine steering.
