The invention relates to an electric drive axle assembly, belongs to the technical field of automobile production and manufacturing, and solves the technical problem that the power supply efficiency of an electric drive axle assembly in the prior art needs to be further improved. The electric drive axle assembly comprises an axle housing. The two motors are both installed in the axle housing, rotating shafts of the two motors face the two sides respectively and extend out of the axle housing, and the rotating shafts of the two motors are directly connected with the two wheel ends respectively. The two motors in the axle housing respectively drive the wheel ends at the two ends of the axle housing to rotate, so that a differential mechanism and a speed reducer do not need to be arranged, and compared with the prior art, due to no power consumption of the differential mechanism and the speed reducer, the loss of power transmitted to the wheel ends by the electric drive axle assembly is smaller, and therefore the power consumption is reduced. According to the electric drive axle assembly, the efficiency of supplying power to the wheel ends is higher, and in addition, the two motors are installed in the axle housing, so that the whole electric drive axle assembly is more compact in structure and smaller in size, and the required space size during installation is smaller.
本发明涉及一种电驱桥总成,属于汽车生产制造技术领域,解决了现有技术中的电驱桥总成的动力供给效率有待进一步提升的技术问题。该电驱桥总成包括桥壳;两个电动机,均安装在桥壳的内部,两个电动机的转轴分别朝向两侧并伸出桥壳,并且两个电动机的转轴分别与两个轮端直接连接。桥壳内的两个电动机分别带动桥壳两端的轮端转动,这样,则不需要设置差速器以及减速器,相较于现有技术而言,由于没有差速器以及减速器的动力消耗,因此,该电驱桥总成传递至轮端的动力损耗更小,故,该电驱桥总成给轮端供给动力的效率更高,另外,两个电动机安装在桥壳的内部,所以整个电驱桥总成的结构更加紧凑,体积更小,安装时所需的空间尺寸更小。
