The invention relates to a drive device for a motor vehicle and a motor vehicle. The drive device has a first and a second electric machine, a first and a second axle shaft for driving wheels, and a switching device equipped with at least a first and a second clutch. And the switching equipment is at least used for realizing a differential function, a differential lock, a torque vector distribution function and disconnection of the second motor and the half shaft. The mechanical differential can replace the switching device, so that weight, structural space and cost can be saved. In the first operating state, the first clutch is open and the second clutch is closed, so that the first half shaft is in driving connection with the first electric machine and the second half shaft is in driving connection with the second electric machine. In the second operating state, the first clutch is closed and the second clutch is opened, so that the two half shafts are in driving connection with the first electric machine and the second electric machine is decoupled from the half shafts. In a third operating state, the first and second clutches are closed such that the two half shafts are connected to each other and are drivingly connected to the two motors.
本发明涉及用于机动车辆的驱动设备以及机动车辆。该驱动设备具有第一和第二电机、用于驱动车轮的第一和第二半轴以及至少配备了第一和第二离合器的切换设备。切换设备至少用于实现差速功能、差速锁、扭矩矢量分配功能和第二电机与半轴的脱联。可以机械差速器取代切换设备,由此可以节省重量、结构空间和成本。在第一运行状态中,第一离合器是断开的且第二离合器是闭合的,从而第一半轴与第一电机驱动连接且第二半轴与第二电机驱动连接。在第二运行状态中,第一离合器是闭合的且第二离合器是断开的,从而两个半轴与第一电机驱动连接且第二电机与半轴脱联。在第三运行状态中,第一和第二离合器是闭合的,从而两个半轴相互连接且与两个电机驱动连接。
