The utility model relates to a constant-speed-engaged stepless speed changing drive of an electric vehicle. The constant-speed-engaged stepless speed changing drive of the electric vehicle comprises a motor, a transmission case and an output shaft, and is characterized in that a motor output shaft which is fixed on the transmission case is connected with a weight roller drive disc in a transmission way, the weight roller drive disc is connected with a clutch by a belt in a transmission way, and a differential speed changer is arranged between the clutch and the output shaft. The stepless speed change is realized by utilizing a weight roller, and the adjustment of an output torque is realized through the differential speed changer. The weight-roller-type stepless speed changer is adopted to overcome the impact of primary high speed of the motor on the vehicle and realize the stepless adjustment of a rotating speed, and then a post-step differential speed changer is assembled to realize the output torque for no
