The invention provides a strong load reducer for a pure electric vehicle. The strong load reducer comprises a front end cover and a rear end cover, wherein the front end cover and the rear end cover are combined to form a reducer shell, the reducer shell is used for supporting an input shaft, a middle shaft and a differential mechanism, which are arranged in the reducer shell and can rotate; the input shaft which is used for being connected with an external power shaft is arranged in the reducer shell, the input shaft is engaged with a middle gear through a gear on the outer circle of the input shaft, the middle gear is connected to the middle shaft in a sleeving manner and can drive the middle shaft to rotate together; the middle shaft is engaged with a driving gear through a gear on an outer circle of the middle shaft, the driving gear is fixedly connected with the differential mechanism and can drive the differential mechanism to rotate together; the differential mechanism is sued for being respectively connected with a left output shaft and a right output shaft of the vehicle, so that the left output shaft and the right output shaft of the vehicle can rotate in different rotation speeds. The reducer is high in transmission power and low in noise, different speed ratios and output torques can be realized on the premise of constant appearance; the differential mechanism can meet the requirement that wheels on two sides of the vehicle have speed difference when in turning.
