The invention discloses an electronic power-assisted braking system which comprises a ball nut, a motor and a main cylinder, the outer side of the ball nut is sleeved with a bearing, the bearing facilitates rotation of the ball nut, a first-stage small gear is fixed to the output end of the motor, one side of the first-stage small gear is meshed with a combined gear, and one side of a small-diameter gear in the combined gear is meshed with a second-stage large gear. A secondary gear mechanism is driven to rotate through a small gear of a combined gear, a spline-like design is arranged on an inner ring of a secondary large gear, a spline-like design is matched with a spline-like design of an outer ring of a ball nut, the ball nut is driven to rotate when the secondary large gear rotates, and then a lead screw conducts linear motion; the lead screw and the input push rod compress the feedback disc till the feedback disc is in a balanced state, then the output push rod is jointly pushed, the main cylinder comple
