The electric drive shaft assembly comprises a front shell, a rear shell arranged at the tail end of the front shell, a stator fixedly connected into the front shell and a rotor assembly arranged on the inner side of the stator, opposite through holes are formed in the front shell and the rear shell correspondingly, the rotor assembly comprises a second connecting shaft penetrating out of the part along the through hole in the rear shell, and the second connecting shaft penetrates out of the rear shell. The second connecting shaft is sleeved with the first connecting shaft, a part of the first connecting shaft penetrates out along the through hole in the front shell, at least one needle bearing is arranged between the second connecting shaft and the first connecting shaft, and the front shell and the rear shell are each provided with a connecting part connected with an engine or a speed reducer and used for being connected with external equipment in a matched mode. According to the electric drive shaft assembly, the matching degree of external equipment of the electric drive shaft assembly is improved, the application range is widened, and meanwhile, the double shafts are rotatably supported through the needle bearings, so that the rotor assembly achieves the purposes of high integration level and compact structure through the arrangement.
