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.

    本发明公开了一种减速器总成和车辆,所述减速器总成包括:驱动件和动力齿轮组,所述动力齿轮组设置于两个车轮半轴之间,所述动力齿轮组包括同轴分布的减速行星齿轮机构和差速行星齿轮机构,所述驱动件与所述减速行星齿轮机构动力连接,所述减速行星齿轮机构与所述差速行星齿轮机构动力连接,所述差速行星齿轮机构与两个所述车轮半轴中的一个车轮半轴动力连接,且所述差速行星齿轮机构与两个所述车轮半轴中的另一个所述车轮半轴选择性地动力连接。本发明的减速器总成,其整体结构更加紧凑,利于减小减速器总成的体积,从而减小对整车搭载空间的占用,同时,在车辆滑行时,可断开减速器总成的内部结构,减少搅油损失,提升效率。
