The invention discloses an integrated electric drive axle assembly and an automobile comprising the same, and belongs to the field of new energy automobiles, a motor, a gearbox, a drive axle and a power takeoff are integrated together, power can be output through the power takeoff according to needs in the automobile running process to provide power for vehicle-mounted accessory devices such as an oil pump and a water pump for operation, and the power takeoff can be used for providing power for the vehicle-mounted accessory devices. The integration degree is high. And the two power sources are coupled to achieve at least seven working modes, the use requirements of multiple working conditions are met, and the application range is wide. The shift gear adopts a hollow shaft structure and is coaxially arranged with the drive axle half shaft, so that the weight suspended outside the axle housing is reduced, and the strength of the speed reducer housing is remarkably improved. And the shortest mechanical transmission path is provided, the transmission efficiency is high, and the device is suitable for full-speed range low-load power driving. According to the power platform, the two use requirements of vehicle running and operation are met, the system power and torque redundancy are reduced, the overall system efficiency is improved, and the cost is saved.
本发明公开了一种集成式电驱动桥总成及包括其的汽车,属于新能源汽车领域,将电机、变速箱、驱动桥、取力器集成到一起,可以在汽车行驶过程中根据需要通过取力器输出动力为随车附属装置如油泵、水泵等装置提供动力进行作业,集成度高。且本发明将两个动力源进行耦合实现至少七种工作模式,满足多种工况使用需求,应用范围广。本发明挡位齿轮采用空心轴结构与驱动桥半轴同轴设置,将悬置于桥壳外的重量减轻,减速器壳体强度显著提升。提供了最短的机械传动路径,传动效率高,适用于全速范围低载荷动力驱动。本发明实现一种动力平台满足车辆行驶和作业两种使用需求,降低了系统功率及转矩冗余,提高了整体的系统效率,节约了成本。
