The invention provides an integrated electric drive axle. The integrated electric drive axle comprises a left half axle housing, a box cover, a main speed reducer and a right half axle housing which are sequentially connected through bolts. The main speed reducer comprises a speed reducer shell, a two-stage two-gear parallel shaft speed reduction shaft system, a differential integrated with a two-gear planet row speed reduction mechanism and a two-stage power-selectable upper power take-off gear shaft system are arranged in the speed reducer shell, and a parallel gear shifting mechanism and a power take-off transmission assembly shell are arranged outside the speed reducer shell. The power take-off device is used for gear shifting of a speed reducer and installation and power take-off power transmission of a power The defects that in the prior art, an existing conventional electric drive axle is few in high-speed and low-speed adjusting gear shifting gears and weak in dynamic property, the use requirement of special working conditions cannot be met, an upper power taking mechanism is lacked, and application of the electric drive axle in the dump truck and special vehicle market is seriously limited can be overcome.
本发明提供一种集成式电驱动车桥,包括通过螺栓依次连接的左半桥壳、箱盖、主减速器和右半桥壳;所述主减速器包括减速器壳体,所述减速器壳体内设有两级两挡平行轴减速轴系、集成两挡行星排减速机构的差速器及两级可选动力的上装取力齿轮轴系,所述减速器壳体外部设置有并联换挡机构和取力传动组件壳体,分别用于减速器换挡以及取力器的安装与取力动力传递。能够克服现有技术中现有常规电驱动车桥高低速调节换挡挡位少,动力性弱,不能满足特殊工况的使用需求,以及缺少上装取力机构,严重限制其在自卸车及专用车市场中应用的缺陷。
