An intelligent recirculating ball steering gear assembly with safety redundancy is characterized in that an input shaft A of an electric steering unit is fixed with a torsion bar through a cylindrical pin, the torsion bar is pressed and fastened on a worm wheel shaft through a spline, a speed reducing mechanism is fastened on the worm wheel shaft through interference fit, and a torque angle sensor is welded and fastened on the input shaft A; the integrated power hardware belt software assembly and the shell are fastened through bolts, a motor unit in the integrated power hardware belt software assembly drives a transmission shaft in the speed reducing mechanism to conduct torque, an input shaft B is connected with a turbine shaft in the electric steering unit through a spline, and the valve body and the shell in the electric steering unit are fastened through bolts. When the input shaft A is stressed to rotate, the input shaft A can be linked with the input shaft B to steer together, and double rotary valves in the double-loop circulating ball steering gear unit are driven to divert flow and each hydraulic unit is driven to assist power. The system has safety redundancy and intelligence, and can meet the safety driving requirements of engineering vehicles and special vehicles.
