The invention discloses a dual-motor drive axle which comprises a first motor and a second motor which are used for providing power for a first inner gear ring, the first inner gear ring is connected with a plurality of output gears and a second inner gear ring through a transmission structure, and a main transmission shaft is selectively connected with one of the output gears or the inner gear rings through a sliding sleeve set. In addition, the invention further discloses a vehicle applying the dual-motor drive axle. According to the dual-motor drive axle, the inner gear ring and the outer gear are used in cooperation, four gears can be achieved only through three rows of gears, the axial size of the drive axle is effectively reduced, the size of the gears can be reduced through the double-intermediate-shaft structural design, and the service life of the drive axle can be prolonged through symmetrical arrangement; and meanwhile, the high-efficiency interval of the motor can be better utilized, so that the transmission efficiency of the dual-motor drive axle is improved.

    本发明公开了一种双电机驱动桥,包括为第一内齿圈提供动力的第一电机、第二电机,所述第一内齿圈通过传动结构连接有若干输出齿轮和第二内齿圈,一主传动轴通过滑套组可选择性的与若干输出齿轮或者内齿圈其中一个连接。此外,本发明还公开一种应用了所述双电机驱动桥的车辆。本发明的双电机驱动桥采用内齿圈和外齿轮配合使用,仅用三排齿轮就可以实现四个挡位,有效地减小了驱动桥的轴向尺寸,并且采用双中间轴结构设计,能够减小齿轮的尺寸,对称设置也有利于延长驱动桥的使用寿命;同时,能够更好地利用电机的高效区间,以提高双电机驱动桥的传递效率。
