Abstract

The invention discloses a pure electric automatic transmission integrated drive axle assembly for an electric automobile and relates to the technical field of electric automobiles. The pure electric automatic transmission integrated drive axle assembly comprises a drive motor, a gearbox, an electromagnetic clutch device, a speed reducer and a differential mechanism. The drive motor is arranged ona rear axle main shaft and provided with a hollow motor shaft. The electromagnetic clutch device comprises a sliding clutch, a flange and an electromagnet. The side, facing the drive motor, of the gearbox is provided with an opening, and the flange is arranged on the portion of the opening of the gearbox. The hollow motor shaft penetrates the flange into the gearbox, and a first free gear and a second free gear are arranged on the portion, penetrating into the gearbox, of the hollow motor shaft in a spaced mode. The hollow motor shaft is sleeved with the sliding clutch which is matched with the first free gear and the second free gear. The speed reducer is provided with a low-speed input end and a high-speed input end, the high-speed input end of the speed reducer is connected with the first free gear, and the low-speed input end of the speed reducer is connected with the second free gear. The differential mechanism is connected with the output end of the speed reducer.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a pure electric automatic transmission integrated drive axle assembly for electric vehicles. Background technique [0002] Electric vehicles use vehicle-mounted power batteries as the power source to drive vehicles.
