The invention provides a bridge driving system and a vehicle. In the bridge driving system, the double motors are included, the torque from the rotors of the motors can be output to the outside through the output shafts which are off-axis arranged with the rotors, and therefore a framework with the double motors and the off-axis arranged output ends is achieved. In addition, the transmission in each bridge driving unit comprises a planet row, so that a torque transmission path for transmitting torque towards the outside is formed. Therefore, compared with an electric bridge driving system which only forms a transmission through an external meshing gear set, the electric bridge driving system has the advantages that a torque transmission path with a large transmission ratio can be realized in a relatively compact structure under the condition of occupying a small radial space, the torque requirement on the motor is correspondingly reduced, the size of the motor can be correspondingly reduced, and the cost of the motor is saved.
本申请提供了一种电桥驱动系统及车辆。在本申请的电桥驱动系统中,包括双电机,来自电机的转子的扭矩能够经由与转子偏轴设置的输出轴输出到外部,由此实现了双电机及输出端偏轴设置的架构。另外,各电桥驱动单元中的变速器包括行星排,来形成朝向外部传递扭矩的扭矩传递路径。因而,与仅通过外啮合齿轮组构成变速器的电桥驱动系统相比,能够在占用较小的径向空间的情况下以相对紧凑的构造实现具有较大传动比的扭矩传递路径,相应地减小对电机的扭矩需求,能够相应地减小电机的尺寸且节省电机的成本。
