The invention provides a middle-engine integrated electric bridge with a driving force distribution function. The middle-engine integrated electric bridge comprises a motor, a first planetary gear speed reducing mechanism, a second planetary gear speed reducing mechanism, an external differential mechanism and an external initiative driving force distribution device, wherein the motor, the first planetary gear speed reducing mechanism and the second planetary gear speed reducing mechanism are arranged along the same axis; and the initiative driving force distribution device comprises a driving force distribution motor and a speed reducer. The two ends of the motor are used for outputting power to sun wheels of the planetary gear speed reducing mechanisms on the two sides, and the power is transmitted to driving wheels through planetary carriers and half shafts; and when a driving force needs to be initiatively distributed, a torque output by the initiative driving force distribution motor is amplified by the speed reducer and then is applied to a driving tapered gear of the differential mechanism so as to drive two half-shaft conical gears of the differential mechanism to rotate in opposite directions, and furthermore, additional torque input is generated on gear rings of the planetary gear speed reducing mechanisms and the torques of the two driving wheels are increased or decreased. By virtue of the initiative driving force distribution function, the operation stability and the initiative safety performance of automobiles are improved.
