The present invention is an amphibious all-terrain vehicle. This amphibious all-terrain vehicle includes a boat-shaped hull and a continuous track system that is configured to provide propulsion at multiple speeds while in water. The amphibious all-terrain vehicle includes a drive train, a suspension system having one or more tracks, an operator's station, and one or more handle bars as a steering system.

The amphibious unmanned patrol vehicle includes a buoy, a waterproof cable and a submersible amphibious vehicle. An end of the waterproof cable is connected to a first controller of the buoy; and another end thereof is connected to a second controller of the submersible amphibious vehicle. A bottom end of the buoy is connected to a top end of the submersible amphibious vehicle which is configured to realize movement and operation of a whole system. The waterproof cable is configured to connect the submersible amphibious vehicle, and the buoy configured to ensure real-time communication between the submersible amphibious vehicle and an external environment during operation of the submersible amphibious vehicle. A height difference between an upper surface and a lower surface of the automatic reeling and unreeling cable device is equal to a thickness of the waterproof cable. The length of the waterproof cable is adjusted automatically in real time.

A special suspension-type tracked underwater robot adaptable to ultra-soft geological conditions comprises traveling mechanisms, wherein the traveling mechanisms are track-mud sled structures, the mud sled structures are fixedly arranged on two sides of each track, and the bottoms of the mud sled structures are higher than the bottoms of the tracks and are provided with arched plate heads; the arched plate heads are provided with plate water-jet devices capable of spraying water forwards; and in the traveling process of the traveling mechanisms, and the arched plate heads press water downwards to form a water film at the bottoms of the mud sled structures together with the water sprayed by the plate water-jet devices, so that the traveling mud resistance is reduced, and the robot can stably advance under ultra-soft geological conditions. The special suspension-type tracked underwater robot further comprises a propelling mechanism, an adjustment device, an operating module, and the like, can autonomously advance on a seabed, can suspend in water, can repair itself when broken, and can achieve detailed operations.

An amphibian (1) for use on land and water, comprising: a hull having a planing surface (2), and at least one retractable suspension apparatus (4) movable from a vehicle supporting position to a retracted position, comprising for each wheel (5), upper and lower suspension arms (8, 9) that are pivotably connected at inboard ends to a support structure within the hull; and are pivotably connected at outboard ends to a suspension upright (7). Upright (7) extends from a first, upper connection past a second, lower connection to a location (10) for a wheel hub mounting. The suspension upright when deployed in land use extends externally of the hull across a side face (2A) of the planing surface; while lower suspension arm (9) remains above the top of planing surface (2) throughout use of the amphibian on land. This suspension arrangement allows the hull to have no cutouts in its planing surface.

The present invention provides an apparatus, method and system for utilizing commercial cargo containers. The present invention utilizes containers made autonomous by coupling a container with a detachable propulsion system, having a motor and navigation and steering controls, permitting the rapid, controlled, efficient and safe delivery of cargo containers individually by water. Ballast units, deployment systems and control via remote units are also disclosed. The containers, utilizing their inherent buoyancy, can move autonomously according to a preplanned or remote controlled route to a specific location.

An amphibious caterpillar vehicle includes a central body of a second buoyancy material of a track shoe is disposed between a pair of wheels. An engagement body of the second buoyancy material of the track shoe is inserted into a buoyancy material engagement groove of each of the wheels so that a driving force is transferred from a driving sprocket to a caterpillar track. A coupling force between driving sprockets and track shoes forming a caterpillar track increases so that the caterpillar track is able to stably receive the driving force without slipping from the driving sprockets.

A transmission for a vehicle, particularly a skid-steered vehicle, that employs motive power from a prime mover delivered through an input shaft to drive left and right drive shafts at a nominal speed and input power from an electric motor to vary the speed of the left and right drive shafts according to steering commands from a steering control structure. The speed of the left and right drive shafts is directly related to a speed of the input shaft and the nominal speed of the left or right drive shaft is varied upwardly or downwardly by a ratio of the speed of the steering shaft via a speed varying structure. The speed of the left and right drive shafts is simultaneously varied in opposite directions (i.e. upwardly and downwardly) relative to the nominal speed by an equal number of rotations.

Vehicle comprising a hull and motorised aquatic propulsion members and motorised land propulsion members, this vehicle being able to move between a navigation position and a land transport position in which it rests on sets of caterpillar tracks. Each set of caterpillar tracks (1) is equipped with an even number of rollers (7) so as to define a set of adjacent roller pairs (71, 72). The rollers (71, 72) of each pair are connected to the chassis (2) by suspension means comprising a set (12) of at least two superposed curved elastic leaves made of a fibre-reinforced thermosetting resin, namely an upper leaf (131) and a lower leaf (132), the set being fixed on the one hand to the axles (9) of the rollers (71, 72) at its respective ends and, on the other hand, to the chassis (2) in its central part, and the upper leaf (13i) and the lower leaf (132) of each of the sets of leaves (12) are joined together and covered with a layer of elastomer (14).

An amphibious vehicle includes: an engine; at least one land traveling device; at least one water propelling device; a power distribution device configured to distribute power outputted from the engine between land travel power to be supplied to the at least one land traveling device and water propulsion power to be supplied to the at least one water propelling device; a slippage-amount detection device configured to detect a slippage amount of the at least one land traveling device relative to ground; and a controller configured to adjust at least the land travel power, of the land travel power and the water propulsion power, on the basis of the slippage amount detected by the slippage-amount detection device. The controller is configured to reduce the land travel power if the slippage amount detected by the slippage-amount detection device is greater than a threshold while the land travel power and the water propulsion power are supplied respectively to the at least one land traveling device and the at least one water propelling device for landing from water to land.
