Abstract
An amphibious vehicle having retractable wheels and sliding hull sections. A novel suspension system is disclosed for raising and lowering the wheels on the vehicle. A coil spring/shock absorber is connected to a linkage which moves horizontally by action of a motor and worm gear coupled to the linkage. The lateral movement of the linkage results in vertical movement of the wheel. The amphibious vehicle may be driven directly into the water, and the wheels raised. Sliding hull sections are then positioned over the wheel wells to give the vehicle a streamline outer hull for water-borne travel.
