ABSTRACT:
An amphibious vehicle is disclosed which is adapted for alternative land and water modes of operation and in which both modes of operation are performed efficiently. The amphibious vehicle includes a vehicle body supported, during land-bound operation, by a front pair of wheels and a rear pair of wheels. Each of the wheels of the vehicle are surrounded by specially-configured fender/sponson units which are rotatable between first and second operational positions through an angle of approximately 180.degree. about the encompassed wheel. In the first operational position, the fender/sponson units function as wheel tenders for land operation. In the second operational position, the fender/sponson units function as sponsons providing floatation to the vehicle and effectively contributing to the streamlined character of the vehicle during traverse through the water by presenting nautical wedges to the water. A rotation mechanism is provided for selectively rotating each of the fender/sponson units between their first and second operational positions. A drive train is provided to selectively propel the vehicle in the land and water modes of operation. The drive train includes a front wheel drive configuration for land-bound operation and a propeller for propelling the vehicle during water-borne operation. A transfer case directs the drive to either the front wheels or the propeller which can be selectively lowered, along with a rudder, for water-borne operation.
