AMPHIBIOUS VEHICLE Russian patent published in 2018 - IPC B60F3/00 

FIELD: transport machinery.

SUBSTANCE: invention relates to the field of transport engineering and concerns the technology of operation of rotor-screw amphibians intended for moving both on land and on water. Amphibious-type vehicle comprises a body with rotor-screw propellers arranged along its sides, provided with a mechanism for changing their position in the vertical plane. Change mechanism is made in the form of onboard rockers fixed to the body by means of bearing supports. Side rockers are made of profiles, along the force element of the axes of which there is a hydraulic cylinder hinged to the lever, the movable rod of which is mounted on the rocker's power element. Rotor-screw propellers are installed in the bearings of the rocker and are equipped with a drive. Rockers are made in the form of a spatial frame, equipped with an arc-shaped stiffener. On the frame there is a lever fixed, rigidly connected to the swing axis installed in the holes of the holders attached to the body. Above the swing axis of the lever there is a hydraulic cylinder mounted on the body, the rod of which is fixed to the lever by means of a fork, and the axes of the hydraulic cylinders changing the position of the propellers are perpendicular to each other.

EFFECT: expansion of the technological capabilities of the amphibious vehicle is achieved.
