The invention relates to the technical field of vehicles, in particular to an electric drive axle and a vehicle. The electrically-driven axle comprises an axle housing, two motors, two first-stage speed reducers, two half shafts, two brake assemblies and two hub speed reducers. The two motors and the two first-stage speed reducers are all arranged in the central axle housing. The input end of the first-stage speed reducer is connected with a motor shaft; one end of the half shaft is connected with the output end of the first-stage speed reducer; the brake assembly comprises brake shells and brake assemblies arranged in the brake shells, the two brake shells are connected to the left axle housing and the right axle housing respectively, the two sets of brake assemblies brake the two half shafts respectively, and the brake assemblies can execute traveling brake and parking brake at the same time; the input end of the hub reduction gear is in transmission connection with the other end of the half shaft, and the output end of the hub reduction gear is connected with the hub. The invention has high reliability, can be suitable for the existing tire size, and provides a scheme capable of simultaneously executing driving braking and parking braking.
