The invention relates to the technical field of automobile transmission, and particularly discloses a double-motor electric drive axle assembly and a vehicle. A plurality of connecting shafts are arranged on a planet support in a protruding mode and correspond to a plurality of planet gears in a one-to-one mode, the planet gears are rotationally connected to the connecting shafts, and the planet gears are meshed with an outer gear ring and a sun gear at the same time; the first driving motor is in transmission connection with the left half shaft and the planet support and can drive the left half shaft and the planet support to rotate, the second driving motor is in transmission connection with the sun gear and can drive the sun gear to rotate, and the transmission mechanism is in transmission connection between the outer gear ring and the right half shaft. Under the condition that the rotating speed of the wheels on one side of the first driving motor is kept unchanged, switching among straight line, left turning and right turning of the vehicle can be achieved only by controlling the rotating speed of the second driving motor, the turning radius of the vehicle is accurately controlled, even left and right wheels can be reversely rotated, in-situ turning is completed, the application scene range is wide, the response speed is high, and the driving reliability is high. And the flexibility of the vehicle is effectively improved.

    本发明涉及汽车传动技术领域,具体公开了一种双电机电驱动桥总成及车辆,其中,行星支架上凸设有若干连接轴,若干连接轴与若干行星轮一一对应,行星轮转动连接于连接轴,行星轮同时与外齿圈以及太阳轮啮合,第一驱动电机传动连接于左半轴与行星支架,并能够驱动左半轴与行星支架转动,第二驱动电机传动连接于太阳轮,并能够驱动太阳轮转动,传动机构传动连接于外齿圈与右半轴之间。在第一驱动电机一侧的车轮转速保持不变的情况下,车辆的直线、左转、右转之间的切换仅通过对第二驱动电机的转速控制就能得以实现,且精准控制车辆的转弯半径,甚至可实现左右轮反转,完成原地掉头,适用场景范围较广,响应速度快,有效提升车辆的灵活性。
