摘要：
FIELD: transportation.SUBSTANCE: wheel-track vehicle for a handicapped person comprises a frame, a chair, a wheel propeller with a front wheel and a pair of rear wheels and a track propeller. The latter comprises a trolley with driving sprockets, guide elements and a pair of tracks with a fracture of transition of their lower branch into the rear one. There are reversible drives of wheel and track propellers, including an electric one, a source of autonomous power supply, brakes and a system of control of motion modes. The control system includes a device for rotation of the front wheel and a device of selective input of one of the specified propellers in interaction with the support surface. The trolley of the track propeller is combined with the frame. The device of selective input of one of the specified propellers in interaction with the support surface is made in the form of a lever suspension of rear wheels with drives of rotation of suspension levers in vertical planes, with the possibility of inclination of lower branches of tracks in backwards-upwards in the wheel-mounted position of the vehicle. The front wheel is arranged in the form of a motor wheel with the possibility of movement of the vehicle in the speed range (up to 20 km/hr), and the device of its rotation - in the form of a steering column with the possibility of rotation of the front wheel in the range of angles ±90°. There is a device of independent rotation of rear wheels, at least the left to the left, and the right to the right in the range of angles from zero to the value providing for kinematic rotation of the vehicle with zero radius. There are additional structural criteria of a device.EFFECT: expansion of technical-operational capabilities due to provision of an additional function of speed motion and transfer of a device of wheel motion - track motion modes change from manual to electromechanical, provision of superior manoeuvring expressed in capability of kinematic rotation on wheel
