The invention provides a power transmission device, an electric drive axle and a vehicle. The power transmission device comprises an input shaft, wherein a first external spline is arranged on the input shaft; the transmission shaft and the input shaft are coaxially arranged; a second external spline is arranged at one end, opposite to the input shaft, of the transmission shaft; the first output gear is hollowly sleeved on the transmission shaft; a third external spline is arranged on the side, close to the second external spline, of the first output gear. The sliding sleeve is arranged on the input shaft in a sleeving manner and can move in the axial direction of the input shaft; wherein the sliding sleeve is provided with a first internal spline and at least one second internal spline; the first internal spline is matched with the first external spline; when the sliding sleeve moves in place, the second internal spline is connected with the second external spline or the third external spline. The power transmission device is simple in structure, compact and reliable.
