Abstract
A retractable suspension system adaptable for land, water, or amphibious vehicles substantially comprises: a bottom suspension arm having a wheel-axle assembly associated with its first end; a top suspension arm; spring means for interconnecting the arms; a horizontal suspension beam axle fixedly attached to the vehicle frame; and means attached to the vehicle frame and to the first end portion of the top suspension arm for adjusting the rotational orientation of the two arms about the suspension beam axle whose center is coincident with the second ends of the two arms. The suspension system can be partially retracted to accommodate for uneven load distributions on the vehicle and for levelling the vehicle on nonuniform terrain while it can be fully retracted for water use. Straight carry-through members which are extensions of the vehicle frame can be utilized to form the suspension beam axle. In such case, a low pivot point is provided for rotation of the top and bottom suspension arms thereby eliminating the need for complicated secondary framing which would otherwise be required.
