The invention relates to and provides a drive apparatus of an electric motor four-wheel drive vehicle, which can realize efficient drive force transmission of an electric motor and improvement of maneuverability. The drive apparatus for an electric motor four-wheel drive vehicle is provided with two electric motors, two differential mechanisms, first to eighth disconnection mechanisms, and a sprocket mechanism. Driving force from an electric motor is distributed and transmitted to a front wheel and a rear wheel through the disconnection mechanisms, the sprocket mechanism and the differential mechanisms which control the disconnection state in a left-right independent mode, so that the differential function on the front wheel and the rear wheel is achieved, and meanwhile left-right torque vectoring distribution is achieved.
本发明涉及并提供一种能够实现电动马达的高效的驱动力传递和操纵性的提高的电动马达式四轮驱动车的驱动装置。电动马达式四轮驱动车的驱动装置具备两个电动马达、两个差动机构、第一断接机构~第八断接机构及链轮机构,通过左右独立地将来自电动马达的驱动力经由控制断接状态的上述断接机构、上述链轮机构以及上述差动机构分配并传递到前轮及后轮,从而发挥前后轮上的差动功能,同时实现左右的扭矩矢量分配。
