Amphibious vehicle

摘要

An amphibious vehicle is disclosed of the type in which the ground engaging wheels are retracted during marine operation. The vehicle has, among other things, an arrangement in which the side surfaces of the tires act to provide a primary water seal when ground engaging wheels are retracted. Such amphibious vehicle also includes a secondary securing mechanism for locking the wheel suspensions in their retracted positions, and means for filling a space between two parts of the suspension with a hydrophobic substance, such as a grease, whenever the wheels are retracted.
