AMPHIBIAN VEHICLE Russian patent published in 2017 - IPC B60F3/00 B60B19/00 

FIELD: transportation.

SUBSTANCE: invention relates to designs of self-propelled amphibian devices. Amphibian vehicle comprises a waterproof body made as hollow with a double bottom and double boards with a waterproof cylinder that connects the inner bottom to the outer bottom in the plane of longitudinal symmetry of the body and serving as a shaft line for a propulsion system drive. The amphibian vehicle comprises a chassis of three-wheel design on an outer suspension at each board made according to arrangement of floating satellites for reversible gears. Axes of rotation of two lower board wheels are displaced from the plane with the axis of rotation of the upper board wheel. Lower board wheels are rotated by the upper board wheel due to friction engagement between the wheels.

EFFECT: invention provides for extended functional capabilities by optimization of an actuating mechanism of a wheel chassis drive.
