The invention provides a power driving assembly and a vehicle, and relates to the technical field of vehicles, the power driving assembly comprises a driving device, a speed reducing device, a differential device, a planet carrier, a first half shaft, a second half shaft and a shell, and an inner gear ring is fixedly arranged on the inner side of the shell; the speed reduction device comprises a speed reduction planet wheel set which is meshed with a first sun wheel and an inner gear ring on an output shaft of the driving device, and all gears in the speed reduction planet wheel set are arranged on a first planet wheel shaft of a planet carrier in a self-rotation mode. The differential gear comprises a third planet wheel, a fourth planet wheel and a fifth planet wheel, the third planet wheel and the fifth planet wheel are fixedly connected and are arranged on a first planet wheel shaft in a self-rotating mode, and the fourth planet wheel is arranged on a second planet wheel shaft of the planet carrier in a self-rotating mode; the fourth planet gear is meshed with the third planet gear and a second sun gear on the first half shaft, and the fifth planet gear is meshed with a third sun gear on the second half shaft. The size and the weight of the power driving assembly are reduced.

本发明提供了一种动力驱动总成及车辆，涉及车辆技术领域，动力驱动总成包括驱动装置、减速装置、差速装置、行星架、第一半轴、第二半轴和内侧固定设置有内齿圈的壳体；减速装置包括分别与驱动装置输出轴上的第一太阳轮和内齿圈啮合的减速行星轮组，减速行星轮组中的各个齿轮可自转地设置在行星架的第一行星轮轴上；差速装置包括第三行星轮、第四行星轮和第五行星轮，第三行星轮和第五行星轮固接，且均可自转地设置在第一行星轮轴上，第四行星轮可自转地设置在行星架的第二行星轮轴上，第四行星轮分别与第三行星轮和第一半轴上的第二太阳轮啮合，第五行星轮与第二半轴上的第三太阳轮啮合。本发明降低了动力驱动总成的体积和重量。
