An integrated electric drive axle comprises two drive motors, two planetary gear reducers and two brakes which are arranged in a cylindrical axle body in a centralized mode, and two power transmission connecting assemblies are further connected to the two sides of the axle body respectively. Each driving motor is connected with one planetary gear reducer and one brake, so that two independent differential power systems are formed, under the condition of the same total output power, compared with an existing electric drive axle, the size can be greatly reduced, the height can be greatly reduced, smooth steering of a vehicle can be achieved under the state that a differential mechanism is omitted, and the service life of the electric drive axle is prolonged. Compared with the prior art, not only are the requirements for the height and the size of an electric drive axle of a low floor and an electric vehicle with the height limitation requirement for a chassis better met, but also the installation and use requirements of the electric vehicle provided with independent and non-independent suspensions can be met, the applicability is extremely high, the design is novel and unique, and the structure is compact and simple, so that the cost is reduced. The method has great popularization and application values.

    一种集成式电驱动桥,包括集中设置在筒状桥体中的两台驱动电机、两个行星齿轮减速器和两个制动器,桥体的两侧还分别连接两个动力传输连接组件。本发明通过各驱动电机分别连接一个行星齿轮减速器和一个制动器,从而构成两个各自独立的差速动力系统,在总输出功率相同的情况下,相比现有电驱动桥可以极大减小体积、降低高度,且在免去差速器的状态下可实现车辆的平顺转向,不仅更好地满足了低地板以及对底盘有高度限制要求的电动汽车对其所配电驱动桥的高度和体积要求,同时,能够满足配置了独立及非独立悬架的电动车辆的安装和使用需要,适用性极强,且设计新颖独特、结构紧凑简单,因此,极具推广和应用价值。
