AMPHIBIA Russian patent published in 2014 - IPC B60F3/00 

FIELD: transport.

SUBSTANCE: inventions relate to transport machine building. In the first version, amphibia for use on ground and on water contains planing hull, three points of wheels mounting, propulsion device. Two of three points for wheels mounting are points for front wheels mounting each one of which is located at each side and in the front half of amphibia. The third point for wheel mounting is point for rear wheel mounting and located in central area in the rear half of amphibia. At each point of wheel mounting one wheel is located. Each wheel is movable between extended position for ground application and retracted position for application on water. Water propulsor contains two impellers or two screw-propellers each one of which is located at each side of rear wheel mounting point. In the second version, amphibia contains ground propulsor. The ground propulsor is one of the wheels. In the third version, amphibia contains primary engine which in ground version of amphibia use provides direct and indirect drive for one of the wheels. Power train for amphibia contains primary engine; the first propeller shaft; combined gearbox, variator and reducing gear; belt drive, the second propeller shaft, the third propeller shaft, the fourth propeller shaft.

EFFECT: better controllability and higher overwater travel speed.
