VEHICLE Russian patent published in 2004 - IPC

FIELD: transport engineering; vehicles with articulated frames. SUBSTANCE: proposed vehicle has engine, transmission, driving and steerable axles and working place of driver arranged on front and rear semiframes hinge-connected to each other. Said semiframes are made in form of two intersecting spatial structures hinge-connected by horizontal axle for relative angular displacement of semiframes in vertical plane. Steerable axle and driver's working place are found on front semiframe. Driving axle, transmission and engine are installed on rear semiframe. Engine and driving axle are installed at different sides of horizontal axle connecting semiframes. At least one resilient suspension member and semiframe relative turning limiter are installed between front and rear semiframes. Invention provides rational weight distribution between axles and considerable cross stability of vehicle when additional equipment, including load-lifting facilities, are mounted on vehicle and reduction of vibrations transmitted through frame to man- operator. EFFECT: provision of compact self-propelled vehicle featuring improved cross stability, reduced vibrations. 3 cl, 4 dwg
