The invention provides a bridge driving system and a vehicle. The bridge driving system comprises a motor, double clutches and two planet rows, and the double clutches, the two planet rows and a rotor of the motor are completely staggered in the axial direction. The double clutch comprises two clutch units, a rotor of the motor is in controlled transmission connection with a sun gear of one planet row through one clutch unit, the rotor of the motor is in controlled transmission connection with a sun gear of the other planet row through the other clutch unit, and planet carriers of the two planet rows are used for transmitting torque to the outside of the bridge driving system. Thus, the bridge driving system is relatively simple in structure and more convenient to disassemble and assemble, adverse effects of other parts of the bridge driving system on the radial size of the motor can be effectively avoided, and in addition, the escape performance of the vehicle comprising the bridge driving system in the wheel slipping state is improved.
本申请提供了一种电桥驱动系统及车辆。在该电桥驱动系统中,包括电机、双离合器和两个行星排,双离合器和两个行星排与电机的转子在轴向上完全错开。双离合器包括两个离合单元,电机的转子与一个行星排的太阳轮经由一个离合单元受控传动联接,电机的转子与另一个行星排的太阳轮经由另一个离合单元受控传动联接,两个行星排的行星轮架用于向电桥驱动系统的外部传递扭矩。这样,本申请的电桥驱动系统的结构相对简单且拆装更方便,能够有效避免电桥驱动系统的其它部件对电机的径向尺寸造成不利影响,此外还改善了包括该电桥驱动系统的车辆在车轮打滑状态下的脱困性能。
