The present invention provides, with reference to FIG. 1, a power train for an amphibian operable in land and marine modes. The power train comprises a prime mover, a first land propulsion device, a first marine propulsion device and a speed change transmission. The prime mover is arranged to drive the first land propulsion device through/via the speed change transmission in land mode. The prime mover, or at least a portion thereof, is located between the speed change transmission and a rearward most part of the amphibian, with the speed change transmission located spaced ahead of, in front of, the prime mover.

A retractable suspension system for use with an amphibious vehicle is provided and includes three rotation points disposed on the vehicle body of the vehicle, three integration points disposed on an integration element of a tire, an actuating device and a damping component, so as to render the retractable suspension system structurally simple and multifunctional.

A vehicle includes a hull defining one or more holes in a keel of the hull. The one or more holes are provided for ice fishing from the one or more holes. The holes include a hatch or a tube extending upwards, for preventing water from entering the hull. The vehicle also includes continuous track assemblies for providing traction on an ice surface. The continuous track assemblies may also provide a motive force when the vehicle is suspended in water. By the hull design, the vehicle may float on the water, allowing the vehicle to access ice surfaces which may otherwise be inaccessible to ice-fishers. The vehicle also increases safety while fishing during thin or unstable ice conditions.

Aspects of the present disclosure generally pertain to an amphibious vehicle (or amphibian) that is viable on land as well as on water. Aspects of the present disclosure more specifically are directed toward an amphibious vehicle that employs hydrofoils and other features, for example, for efficient cruising when in water. The amphibious vehicle may be embodied as a personal amphibious vehicle.

A MEUV that is able to navigate aerial, aquatic, and terrestrial environments through the use of different mission mobility attachments is disclosed. The attachments allow the MEUV to be deployed from the air or through the water prior to any terrestrial navigation. The mobility attachments can be removed or detached by and from the vehicle during a mission.

A tracked, amphibious vehicle, comprising at least two, spaced, elongated pontoons disposed generally parallel to one another. A platform structure can be supported by and structurally connects the pontoons, the platform structure including a transom, a lowermost generally horizontally extending panel above a free clearance area under a bottom panel and between the pontoons through which terrain and debris can pass. A hydraulic drive system can propel the vehicle, said drive system including left and right hydraulic motors mounted on the pontoons. At least one series of longitudinally spaced bogie wheels for supporting said vehicle can be mounted along the bottom of the pontoons. A continuous, endless belt can encircle each pontoon and engages the bogie wheels. Ground-engaging cleats assembled on the outer surface of each belt and covering the pontoon bottom provide traction to the vehicle. Gearing interfaces the motor with the endless belts. A supplemental, marine drive assembly includes: a hydraulic motor having a rotary device, shaft, with an axis, a propeller shaft having an axis wherein the motor axis and propeller axis are aligned, a universal joint connecting the hydraulic motor to the transom, and a housing including a sleeve that contains the propeller shaft, a first vertical plate connected to the sleeve and a second vertical plate connected to the sleeve below the first plate.

A vehicle (20) consisting of a frame (22) with a pair of paddles (72) extending longitudinally and rotatably supported by the frame (22) in pendulum fashion for swinging movement between an extended position engaging the surface and a retracted position moved vertically out of engagement with the surface. A pair of foot platforms (74) are operatively connected to the paddles (72). A pair of depressors (84) interconnects the foot platforms (74) and the paddles (72) to rotate the paddles (72) between the extended position and the retracted position. The paddles (72) include a propulsion bar (86) and an oar (88) connected by a lost-motion connection to slide relative to one another between the extended position and the retracted position. The oars (88) have a fin-shape to propel the vehicle (20) over water and include a striker (90) to propel the vehicle (20) over land. The vehicle (20) allows movement over a surface of water and land using an elliptical motion similar to the natural motion of walking.

An amphibious pumping vehicle has a floatable vehicle body, a ground engaging propulsion structure, a fluid pump, a plurality of fluid nozzles comprising a first fluid nozzle connected by a fluid conduit to the fluid pump and at least one second fluid nozzle connected to the fluid conduit, a valve structure in the fluid conduit, the plurality of fluid nozzles and the valve structure co-operating to provide directional control and motive power for the vehicle when floating, and a power source configured to provide power to both the ground engaging propulsion structure and the fluid pump.

An amphibious pumping vehicle comprising: a floatable vehicle body; ground engaging propulsion structure configured to raise and lower relative to the vehicle body; a fluid pump; a first fluid nozzle configured to direct fluid through the air, the fluid nozzle connected by a fluid conduit to the fluid pump; and, a power source configured to provide power to both the ground engaging propulsion structure and the fluid pump. The vehicle is particularly well suited to pumping and recirculating fluid within manure lagoons and is able to be driven up out of the lagoon when the lagoon level has been lowered.

A retractable suspension system for use with an amphibious vehicle is provided and includes three rotation points disposed on the vehicle body of the vehicle, three integration points disposed on an integration element of a tire, an actuating device and a damping component, so as to render the retractable suspension system structurally simple and multifunctional.
