The invention discloses a dual-motor synchronous-driving steering actuator of an automobile steer-by-wire system. The dual-motor synchronous-driving steering actuator aims at improving the steering actuating response characteristics and life of the steer-by-wire system and the structural redundancy safety and structural compactness of a steering actuating system. The dual-motor synchronous-driving steering actuator comprises two same steering motors, two same worm-gear reducer assemblies, torque angle sensors and a rack and pinion steering gear assembly. According to the dual-motor synchronous-driving steering actuator, the dual motors and the worm-gear reducer assemblies which are reversely and symmetrically arranged are adopted, the two steering motors and worm-gear reducers assembled with the steering motors are meshed with racks of rack and pinion steering gears, and the torque angle sensors are embedded into the worm-gear reducer assemblies.
