FIELD: transport.
SUBSTANCE: proposed chassis comprises frame composed of tubes and engaged via track variation gear with the wheels. Track variation mechanism is composed by crack-knee slide-crank mechanism. Piston rod can axially displace along the tube and is articulated with wheel axles by levers-knees. The latter are articulated by one end with the frame one side. This track variation mechanism is additionally provided with second levers-knees arranged parallel with first levers-knees. Said second levers-knees feature size of first lever-knees and have one end articulated with the frame outer side, behind said first levers-knees, in one plane. Opposite ends of said lever-knees are secured at extra ties parallel with the frame axis to connect first and second levers-knees to make parallelograms. Wheel axles are fitted at extra ties.
EFFECT: track variation without special extra appliances.
