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 arranged on the inner side of the shell; the speed reduction device comprises a speed reduction planet wheel set 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 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 arranged on a second planet wheel shaft in a self-rotation mode, at least part of the second planet wheel shaft is axially overlapped with the first planet wheel shaft, and the fourth planet wheel is arranged on a third planet wheel shaft in a self-rotation 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.
