The invention relates to a drive axle and a vehicle, and the drive axle comprises a differential mechanism which comprises a power input part; the first motor comprises a first output shaft; the gear shifting structure is in transmission connection with the first output shaft and the power input part and can be controllably switched between a plurality of gear engaging states and a neutral gear state, and the transmission ratios of the first input shaft and the power input part in different gear engaging states are different; the first input shaft in the neutral gear state is separated from the power input part; and the second motor comprises a second output shaft, and the second output shaft is in transmission connection with the power input part. The first motor is matched with the gear shifting mechanism and the second motor, so that the vehicle can obtain enough torque under different road conditions, the torque is reasonably distributed through the gear shifting mechanism, the first motor and the second motor are always in an efficient working interval, and the power performance of the vehicle is effectively improved.
本申请涉及一种驱动桥和车辆,所述驱动桥包括:差速器,包括动力输入部;第一电机,包括第一输出轴;换挡结构,传动连接所述第一输出轴和所述动力输入部,并可受控地在多个挂挡状态以及空挡状态之间切换,不同所述挂挡状态下的所述第一输入轴与所述动力输入部的传动比不同,所述空挡状态下的所述第一输入轴与所述动力输入部相互分离;第二电机,包括第二输出轴,所述第二输出轴与所述动力输入部传动连接。通过第一电机配合换挡机构以及第二电机,使得车辆在不同路况下均能够获得足够的扭矩,并且通过换挡结构合理的分配扭矩,使得第一电机和第二电机始终处于高效的工作区间,有效提高车辆的动力性能。
