The invention relates to an integrated electric drive axle and a vehicle, and belongs to the technical field of axles. The integrated electric drive axle comprises a motor, a speed reducer and a differential mechanism which are integrated together, the speed reducer comprises a power dividing mechanism, the power dividing mechanism comprises an input shaft system, at least two parallel intermediate shaft systems and an output shaft system, the input shaft system comprises an input gear connected with the motor, and each intermediate shaft system comprises an intermediate gear assembly. The output shaft system comprises an output gear, the intermediate gear assemblies are externally meshed with the input gear and the output gear at the same time to achieve power division and power convergence, and the output gear is fixedly arranged on a differential mechanism shell of the differential mechanism. According to the power dividing mechanism, on the premise that enough output torque is guaranteed, the size of each gear is reduced, the occupied space of the speed reducer is smaller, all the gears are in an external meshing relation, the structure is simple, and later repair and maintenance are convenient. And the output gear is directly and fixedly connected with the differential mechanism, so that the occupied space can be further reduced.
本发明涉及一种集成电驱桥及车辆,属于车桥的技术领域。集成电驱桥包括集成在一起的电机、减速器和差速器,减速器包括功率分流机构,功率分流机构包括输入轴系、并行的至少两个中间轴系以及输出轴系,输入轴系包括与电机相连的输入齿轮,中间轴系包括中间齿轮组件,输出轴系包括输出齿轮,各中间齿轮组件同时与输入齿轮、输出齿轮外啮合以实现功率分流和功率汇聚,所述输出齿轮固设于差速器的差速器壳体上。功率分流机构在保证足够输出扭矩的前提下减小了各齿轮的尺寸,使得减速器占用的空间更小,而且各齿轮均为外啮合的关系,结构简单,后期的维修、保养均较为方便。输出齿轮与差速器之间为直接固连的关系,能够进一步减小占用的空间。
