ABSTRACT:
An apparatus for retracting axle-driven wheels onboard an amphibious vehicle provides a retracting process by which the wheels of the vehicle may be moved from a land-support position, to a water-borne position wherein the wheels are substantially above the waterline of the vehicle when afloat. The wheels are axle-driven, with pivotable connections allowing the axles to guide the retracting process; steering connections are pivotably able to follow the process, and steering motion is self-cancelling in the retracted mode. Suitable compartments enclose and support the apparatus in all positions, and seals are provided at the axles to prevent water entering the vehicle interior. A variety of devices may be employed to actuate the apparatus, and also to provide suspension to the vehicle on land.
