A completely transparent spherical body is surrounded externally by a plurality of leaf plates arranged in equal spacing along a main outer ring rack of the spherical body. Two rubber tires are included to wrap the spherical body. A rider inside the spherical body pedals to rotate the spherical body forward. A vehicle having the spherical body can be autonomously operated to move on land or water, and in the air. In addition, to operate this vehicle, no specific road or environmental requirement is needed, and no other obstacle, even a traffic accident can stop its movement.

The present invention provides, with reference to FIG. 2, an amphibian operable in land and marine modes, the amphibian comprising a hull, at least one discontinuity (wheel bay) provided in the hull, and at least one retractable wheel or track assembly at least partially located in the at least one discontinuity (wheel bay). The hull is a planing hull, and the at least one discontinuity (wheel bay) is provided in the front half of the hull of the amphibian. The amphibian further comprises at least one conduit which opens, or is provided with an entry which opens, into or at the at least one discontinuity (wheel bay) and is configured for channelling, in use, fluid away from the at least one discontinuity (wheel bay).

A two wheeled planing amphibian (10) has a hull (20), bow (24), front wheel (30) and rear wheel (40). Front suspension (32) and rear suspension (42) are retractable, separately or simultaneously. Front wheel (30) may retract vertically or rotationally. Steering is by handlebars (50), link (54), and forks (36). Front wheel (20) may be located outside the hull in both protracted and retracted positions. The underside of hull (20) may be continuous in both land mode and marine mode along and across its centreline from the bow to the rearmost underside point on the hull along the centreline; or from the forwardmost underside point on the hull when it is planing at its lowest speed to the rear. There may be no wheel closures attached to the hull. A wheel bay (22), which is open at its top side, may be provided to allow rear wheel retraction.

A two-wheel mobile apparatus that is movable on land and water includes a cabin and a propulsion unit. The cabin is configured to be watertight to a height above a waterline when the mobile apparatus moves on water. Further, the cabin accommodates an occupant and isolates the occupant from the outside of the cabin. The propulsion unit includes a rotatably driven impeller and moves the mobile apparatus on water. An orientation detection unit that detects orientation of the mobile apparatus. A tilt correction unit corrects tilt of the mobile apparatus on land. An oscillation reduction unit reduces oscillation of the mobile apparatus on water. An orientation control unit switches between actuation of the tilt correction unit and actuation of the oscillation reduction unit based on a detection value of the orientation detection unit.

A power train for an amphibian operable in land and marine modes includes a prime mover having an integral speed change transmission, at least a first land propulsion unit, at least a first marine propulsion unit, and a power transmission unit including a drive member configured to couple the prime mover to the at least first marine propulsion unit, wherein the prime mover is arranged to drive the at least first land propulsion unit through/via the integral speed change transmission in the land mode, and the prime mover is arranged to drive the at least first marine propulsion unit through/via the power transmission unit in both the marine mode and the land mode.

The present invention provides a smart mobile vehicle comprising a vehicle body, a chassis, driving wheels, a battery module, a plurality of motors and a vehicle control unit. The chassis has a suspension system, a brake system and a steering system. The two driving wheels are composed of a plurality of circular units, and the driving wheels are embedded in two-wheel frames on two sides of the vehicle body. The battery module provides the smart mobile vehicle with driving power. The plurality of motors disposed between the two circular units or on a surface of any one of the circular units; wherein the motors are electrically connected to the battery module, and the torque and directional outputs of the motors is used to drive the rotation of the two driving wheels. The vehicle control unit is electrically connected to the motors and the battery module to transmit a monitoring signal.

An amphibious motorcycle with a hull that provides desirable buoyancy for the vehicle to float while in the water and yet allows the vehicle to lean/turn during use on land is provided. The amphibious motorcycle has a front wheel with a front suspension system and a rear wheel with a rear suspension system. Also included can be at least one wheel retraction system that is operable to move the front wheel and/or the rear wheel between a deployed position for use of the amphibious motorcycle on land and a retracted position for use of the amphibious motorcycle on or in the water. The amphibious motorcycle also has a hull that can have a center portion with a center bow and two oppositely disposed and spaced apart side portions each with a side bow.

The present invention includes a retractable single front wheel or track drive assembly for an amphibian comprising a single front wheel or track drive. The retractable single front wheel or track drive assembly comprises an actuator, a suspension assembly movable between a protracted position and a retracted position, and a single front wheel or track drive. When the suspension assembly is protracted then the suspension assembly supports and/or holds the single front wheel or track drive in a ground engaging position for use on land, and the front single wheel is moved forward and upwards on retraction. The present invention also provides a retractable single rear wheel or track drive assembly for an amphibian. The present invention further provides an amphibian comprising the retractable single front or rear wheel or track drive assembly.
