Right-arranged left-out intelligent steer-by-wire system

The invention relates to the technical field of steer-by-wire, in particular to a right-arranged left-out intelligent steer-by-wire system. Comprising an input shaft of which the input end is connected with an external steering wheel; the primary speed reducing mechanism is connected with an output shaft of the motor and transmits the output torque of the motor; the ball-following reducing mechanism is connected with the primary reducing mechanism; a gear sector of the rocker arm shaft is in meshed connection with a flat tooth of the recirculating ball speed reducing mechanism; the horizontal pushing assembly is arranged at the bottom of the rotating axial direction of the rocker arm shaft; and the elastic assembly can be elastically arranged at the bottom of the horizontal pushing assembly, the horizontal pushing assembly is driven to press the rocker arm shaft based on compensation force provided by compression of the elastic assembly, and a gap between the rocker arm shaft and the recirculating ball speed
