AMPHIBIAN VEHICLE Russian patent published in 2022 - IPC B60F3/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, in particular to amphibious vehicles. The amphibious vehicle comprises a body, an energy source, a vehicle motion control system, and wheels. The wheels include a rim and a stationary hub with a cavity. A retractable underwater wing is placed in the cavity. The wing is mounted for rotation on an axis fixed at the edges of the cavity and is equipped with a propeller electric drive with an angular velocity sensor. The wing is pivotally connected to a linear electric drive. One end of the linear electric drive is fixed on the wing, and the other end - on the sleeve. The bushing is equipped with a wheel rim angular velocity sensor. Wheel suspension elements are pivotally attached to the body and to the fixed bushing. Racks with axles are fixed on the fixed bushing, on which the wheel rim rests. The inner surface of the wheel rim contains a crown with internal teeth. The crown is connected to a rim rotation drive fixed on a fixed bushing. The drives of the electric motors are attached to the electronic unit fixed on the sleeve. The electronic unit is connected to the wheel rim angular velocity sensors, the propeller drive electric motor angular velocity sensor and the hydrofoil rotation angle sensor around the axis.

EFFECT: increase in reliability of operation.
