AMPHIBIOUS VEHICLE (EMBODIMENTS) Russian patent published in 2020 - IPC B62D55/00 

FIELD: transportation.

SUBSTANCE: invention relates to embodiments of amphibious vehicles, which relate to vehicles capable of movement on water, by land, as well as both on water and by land, with a field of application, which includes movement in waterlogged area, crossing river beds and movement along water reservoirs in off-season, in summer and winter time. According to the first embodiment, the amphibious vehicle from each side has a working surface of the propulsor formed by a caterpillar tape, bypass rollers of which is a pair of non-rotary pneumatic wheels of the same bead. Pairs of each side on two non-revolving pneumatic wheels have axes, which are located above the waterline and which on the side of each bead are located with constant distance from each other, and have their rotary drive in form of actuator of rotary action with axis of rotation, located between axes of pneumatic wheels of one side. Actuator of rotary action engages with outer side of idle run of caterpillar belt and forms its concave section located below upper limits of pneumatic wheels. According to the second embodiment, amphibious vehicle has paired on each side in amount of more than two fixed pneumatic wheels, axes of which are located above waterline and have invariable distance from each other. From each side there is a working surface of the propulsor, which is formed by a caterpillar tape, bypass rollers of which is a pair of extreme pneumatic wheels of one side. From each side there is one actuating element of rotary action, which engages with outer side of idle run of caterpillar belt and forms its concave section located between nearest pneumatic wheels of one bead, below their upper boundaries.

EFFECT: higher running qualities.
