The invention relates to a dual-motor drive axle device and a vehicle, the dual-motor drive axle device comprises a drive axle shell, a differential mechanism, a drive mechanism and two transmission assemblies, and the differential mechanism is in transmission connection with two half shafts; the driving mechanism comprises two driving motors and a first-stage parallel shaft type speed reducer, and the two driving motors are in transmission connection with the differential mechanism through the first-stage parallel shaft type speed reducer; the two transmission assemblies comprise brakes and planetary reducers, and the differential mechanisms are sequentially connected with the brakes and the planetary reducers through two half shafts respectively. The first-stage parallel shaft type speed reducer is arranged, the first-stage parallel shaft type speed reducer is in transmission connection with the differential mechanism, and meanwhile the differential mechanism is sequentially connected with the brake and the planetary speed reducer through the two half shafts, that is, the differential mechanism is arranged between the first-stage parallel shaft type speed reducer and the planetary speed reducer; therefore, the differential mechanism can be integrated with the first-stage parallel shaft type speed reducer, the torque borne by the differential mechanism is smaller, and then the reliability of the whole structure can be improved.

    本发明涉及一种双电机驱动桥装置和车辆,双电机驱动桥装置包括驱动桥壳体、差速器、驱动机构及两传动总成,差速器传动连接两半轴;驱动机构包括两驱动电机及一级平行轴式减速器,两驱动电机均通过一级平行轴式减速器与差速器传动连接;两传动总成包括制动器、行星减速器,差速器分别通过两半轴依次连接制动器及行星减速器。本发明通过设置一级平行轴式减速器,且一级平行轴式减速器与差速器传动连接,同时差速器分别通过两半轴依次连接制动器及行星减速器,即差速器设置于一级平行轴式减速器与行星减速器之间,使得差速器能够和一级平行轴式减速器集成在一起,使得差速器所承受的扭矩较更小,进而能够提高整体结构的可靠性。
