FIELD: transport. ^ SUBSTANCE: invention relates to multiaxle trucks. Proposed system comprises cabin, cargo platform, engine, transmission, running gear and control system. Cargo platform is mounted on two wheeled bogies. Wheeled bogie top and bottom rotary supports accommodate guide posts with their axles supporting balance levers and wheels. Wheeled bogie top part accommodate top reduction gears engaged via gimbal drive with central reduction gears of dual spaced apart final drives with their driven shafts engaged with wheel reduction gears. Wheeled bogies accommodate power hydraulic cylinders. Guide post thrust disks are fitted in slots of hydraulic cylinder piston heads. Two-stage ordinary planetary mechanism is engaged via shafts and reduction gears with combined steering mechanisms. Screw-ball nut-toothed rack-variable gear ratio gears. Gear wheels are locked on bottom rotary supports of guide posts while toothed racks are articulated with rods and pistons of steering hydraulic cylinders. Said power hydraulic cylinders and those of guide posts are communicated via hydraulic lines with pump station, oil tank, control and servo components. ^ EFFECT: expanded operating performances. ^ 5 dwg |
