The invention belongs to the technical field of electric wheel sets, and particularly relates to an integrated electric wheel set based on two-stage speed reduction and a vehicle, the integrated electric wheel set comprises a hub motor, a two-stage planetary reducer, a brake and a hub assembly; wherein the two-stage planetary reducer comprises a first-stage NGW planetary reducer and a second-stage NW planetary reducer; the output end of the hub motor is connected with the input end of the first-stage NGW planetary reducer, and the output end of the first-stage NGW planetary reducer is connected with the input end of the second-stage NW planetary reducer; the brake is arranged on the hub assembly, and the hub assembly is arranged on the hub motor. Two-stage speed reduction is carried out through the two-stage planetary reducer, the speed ratio is increased, the output torque needed by the heavy off-road vehicle is met, meanwhile, the axial length of the electric wheel set is shortened through the hub motor, and space is provided for arrangement of a vehicle suspension.

    本发明属于电动轮组技术领域,具体涉及一种基于双级减速的集成式电动轮组及车辆,包括轮毂电机、双级行星减速器、制动器和轮毂总成;其中,所述双级行星减速器包括一级NGW行星减速器和二级NW行星减速器;所述轮毂电机的输出端连接所述一级NGW行星减速器的输入端,所述一级NGW行星减速器的输出端与所述二级NW行星减速器的输入端相连接;所述制动器设置在所述轮毂总成上,所述轮毂总成设置在所述轮毂电机上。本发明通过双级行星减速器来双级减速增大速比,满足重型越野车辆所需的输出扭矩,同时采用轮毂电机缩短电动轮组的轴向长度,为车辆悬架的布置提供空间。
