The invention is composed of engine, stepless transmission, stepped transmission, differential, steering gear, transmission box, lifter, lumped brake, tripod, frame, circuit, oil circuit, solenoid valve and sensor, etc., and is a A non-memory, non-angle, instantaneous, and linear power steering system that can steer without displacement, avoiding the memory and nonlinearity of mechanical steering in angle and trajectory, and saving a lot of computing costs for intelligent driving. The solenoid valve directly controls the steering gear , CVT, brakes and lifters, etc., are beneficial to remote control, automatic driving, assisted driving and network driving, and gain advantages in maintenance, safety, operation and car popularization; this system has four-wheel drive and eight-wheel drive, four-wheel drive The four-wheel drive is mainly equipped with cars, and the eight-wheel drive is mainly equipped with harvesters; such a harvester does not require car transportation, which is conducive to passing extreme roads, the cab is not super high, and there is also intelligent driving when driving, which saves a truck for practitioners increase people's willingness to buy a machine.
