一种用于电动汽车的集成电机和变速器的同轴驱动桥及方法
摘要：
本发明公开了一种用于电动汽车的集成电机和变速器的同轴驱动桥及方法，涉及新能源汽车领域，该同轴驱动桥包括电机、变速器、差速器和中空轴；所述电机、变速器和差速器同轴布置；电机的一侧设置有差速器；所述差速器与变速器之间通过中空轴连接；所述中空轴置于电机的转子中心内；电机的驱动力经过变速器传递到差速器，经差速器传递到左侧输出部件和右侧输出部件上；通过将电机相对于驱动桥同轴布置，半轴穿过电机的空心轴实现，将电机与变速器同轴设置，集成电机和变速器的同轴驱动桥不会增加车辆悬架的簧下质量，不会对车辆平顺性产生不利影响。相对于轮毂电机，电缆布线费用水平降低，EMC问题减少，电机的水冷却系统简单方便。
摘要（英）：

The invention discloses a coaxial drive axle used for an electric automobile and integrating a motor and a transmission and a method and relates to the field of new-energy automobiles. The coaxial drive axle comprises the motor, the transmission, a differential mechanism and a hollow shaft. The motor, the transmission and the differential mechanism are coaxially arranged. The differential mechanism is arranged on one side of the motor. The differential mechanism and the transmission are connected through the hollow shaft. The hollow shaft is arranged in a rotor center of the motor. The drive force of the motor is transmitted to the differential mechanism through the transmission and transmitted to a left output component and a right output component through the differential mechanism. Themotor is coaxially arranged relative to the drive axle, an axle shaft penetrates through the hollow shaft of the motor, the motor and the transmission are coaxially arranged, and the coaxial drive axle integrating the motor and the transmission cannot increase the unsprung mass of a vehicle suspension and cannot generate an adverse effect on vehicle smoothness. Compared with a hub motor, the motorhas the beneficial effects that the cable arrangement cost level is reduced, an EMC problem is solved, and a water cooling system of the motor is simple and convenient to use.
