Abstract: This invention relates to an amphibious vehicle and especially to an amphibious vehicle having twin internal combustion engines propelling the vehicle in water with a pair of water jet drives and propelling the vehicle on land with one of the same engines having an electric generator powering a pair of electric motors each coupled to a track assembly. Each electric motor and each air brakes are controlled separately to steer and brake the track assemblies.

Abstract: This invention relates to an amphibious vehicle and especially to an amphibious vehicle having twin internal combustion engines propelling the vehicle in water with a pair of water jet drives and propelling the vehicle on land with one of the same engines having an automatic transmission controlling a pair of track assemblies with a pair of planetary gears, clutches and disc brakes.

Abstract: The amphibious vehicle is a motorized vehicle capable of travel on land as well as in the water. The amphibious vehicle has a boat-like hull and a caterpillar track assembly mounted along each side by a respective pair of rotating supports. The tracks are arranged so that the tracks can be rotated between a lowered position supporting the amphibious vehicle and providing traction and propulsion during land operation, and a raised position, where the tracks rest vertically above the hull's deck during marine operation. With the caterpillar track assemblies in the raised position, the caterpillar track assemblies are fully removed from the water to improve performance and maneuverability therein. The track assemblies are hydraulically driven to rotate the wheels and tracks between the lowered and raised positions.

Abstract: The amphibious vehicle is a motorized vehicle capable of travel on land as well as in the water. The amphibious vehicle has a boat-like hull, and a caterpillar track assembly mounted along each side by hinges. The tracks are arranged so that they can be rotated between a lowered position, where they support the amphibious vehicle and provide traction and propulsion during land operation, and a raised position, where they rest vertically on or above the hull's deck during marine operation. With the caterpillar track assemblies in the raised position, the caterpillar track assemblies are fully removed from the water to improve performance and maneuverability. Additionally, with the tracks in their upright position the overall width of the amphibious vehicle is narrowed to facilitate trailering. The tracks employ hydraulic motors in a direct drive configuration for propulsion, reducing weight and complexity of the tracks.
