SMALL-SIZED TRACKED ALL-TERRAIN VEHICLE WITH ELECTROMECHANICAL TRANSMISSION ENTIRELY LOCATED IN UNDERTRACK SPACE Russian patent published in 2023 - IPC B60F5/00 B60F3/00 B62D63/02 B60K6/20 B62D55/00 

FIELD: transport equipment.

SUBSTANCE: devices for all-terrain vehicles and snow and swamp-going vehicles. A small-sized tracked all-terrain vehicle with an electromechanical transmission, characterized in that it contains a power frame, tracked movers, as well as an internal combustion engine generator installed in the power frame and interconnected, which in turn is connected to two gas tanks, two traction electric motors, each of which is connected to its traction inverter, an energy storage device and a control unit, wherein the power frame contains a floor, roof and walls forming a common internally useful displacement space, combined with additional displacement useful spaces located on both sides of the common internal useful displacement space in the under-track contour of the movers, in this case, the traction electric motors are installed in the front part of the power frame in a block with gearboxes and connected to the drive wheel assembly by a cardan transmission to organize the front drive of the tracked propulsion unit or installed outside the front part of the power frame and are made in the form of direct electric motors-wheels as drive wheels, with the internal combustion engine being the generator is installed completely in the additional displacement useful space of one of the under-track contours, and the energy storage device is installed completely in the opposite displacement useful space of the other under-track contour and is equal in weight to the internal combustion engine generator, while the gas tanks are installed completely in both displacement useful spaces of the under-track contour of the movers, have the same design, identical capacity and overflow system.

EFFECT: simplifying the design and increasing reliability, reducing weight and size parameters, ensuring movement at a high maximum speed and away from gas stations, including under any climatic conditions, ensuring the best weight distribution and increased usable space for accommodating the crew and cargo, increasing the overhaul mileage and reduction of labor costs for repairs and maintenance.
