The invention discloses a speed reducer assembly and a vehicle, the speed reducer assembly comprises a driving part and a power gear set, the power gear set is arranged between two wheel half shafts, and the power gear set comprises a speed reduction planetary gear mechanism and a differential planetary gear mechanism which are coaxially distributed; the driving part is in power connection with the speed reduction planetary gear mechanism, the speed reduction planetary gear mechanism is in power connection with the differential planetary gear mechanism, and the differential planetary gear mechanism is in power connection with one of the two wheel half shafts. And the differential planetary gear mechanism is selectively in power connection with the other one of the two wheel half shafts. According to the speed reducer assembly, the overall structure is more compact, the size of the speed reducer assembly is reduced, and therefore the occupied carrying space of the whole vehicle is reduced, meanwhile, when the vehicle slides, the internal structure of the speed reducer assembly can be disconnected, oil stirring losses are reduced, and efficiency is improved.
