The invention relates to a vehicle electric drive axle assembly and a vehicle. The vehicle electric drive axle assembly comprises a motor which is used for providing torque and comprises a first drive motor; the speed reducer is connected with the driving motor and comprises a planet row speed reducer, a differential mechanism and a connecting shaft system, the planet row speed reducer is connected with the connecting shaft system, the planet row speed reducer is further connected with the differential mechanism, and the differential mechanism is connected with a left half shaft and a right half shaft of the vehicle; and the gear shifting execution assembly is connected with the speed reducer and comprises a first gear shifting executor, and the first gear shifting executor is connected with the connecting shaft system. The gear can be reasonably adjusted according to the actual situation so that the speed reduction effect can be achieved, the requirement for large torque of the gear and the requirement for high speed of the high gear can be fully considered, the motor can work in a high-efficiency interval, and the energy utilization rate is greatly increased.
