FIELD: transport.
SUBSTANCE: proposed device comprises, at least, two drive oval wheels. Every oval wheel is formed by two unequal arcs. One larger arc is somewhat larger than wheel semicircle and connected with larger-radius arc with its center misaligned with rotational axis. Both oval wheels are arranged vertically and in parallel but with larger and smaller turned in symmetry in opposite sides to make integral surface of rotation equal to radius of larger arcs aligned partially (in parallel) with two points of circle. To eliminate unbalance caused by rotation, every wheel is furnished with counterweight while shape of every disc complies with that of wheel oval.
EFFECT: higher flotation, better traction.
