FIELD: transport.
SUBSTANCE: invention relates to automotive industry, particularly, to wheel-track vehicles and may be used for increasing flotation on weak soil, etc. Chassis is composed of two rows of taper rims 1 with gears of outer gearing along helical generatrix and tire-tracks 2 running over rims 1. Inner row of rims is fitted on hollow shafts 3 mounted on aligned shafts 4 that double as seats of outer row of rims. Inner row rims 1 are coupled in pairs by tire-track 2. Said coupling in outer row is made with shift L relative to inner row coupling of rims 1. External rims are composed of endless elastic elements with toothed rim over entire inner generatrix while torque is transmitted by dual double-sided free running coupling.
EFFECT: unified drive system.
