The invention discloses a rear drive power assembly device and a vehicle. The rear drive power assembly device comprises a transverse engine and a longitudinal transmission, wherein the transmission comprises a first clutch, a second clutch, an inner input shaft, an outer input shaft, a first intermediate shaft, a second intermediate shaft and an output shaft; the engine is connected with the first clutch, a first input bevel gear pair and the inner input shaft in sequence, and is also connected with the second clutch, a second input bevel gear pair and the outer input shaft in sequence; driving gears of a forward gear pair are distributed on the inner input shaft and the outer input shaft, and driven gears are distributed on the first intermediate shaft and the second intermediate shaft; the driven gears are connected with the first intermediate shaft or the second intermediate shaft through corresponding synchronizers; and the first intermediate shaft and the second intermediate shaft output power to the output shaft through a first intermediate gear pair and a second intermediate gear pair respectively. An existing transverse engine can be reserved to the maximum extent, and the platformization and modularization design of a power assembly device, especially the engine, is achieved as much as possible; and the longitudinal transmission can be designed on the basis of an existing transverse transmission, the development period is shortened, and the development cost is reduced.

    本发明后驱动力总成装置及车辆,包括横置的发动机和纵置的变速器;变速器包括第一、二离合器,内、外输入轴,第一、二中间轴以及输出轴;发动机既与第一离合器、第一输入锥齿轮副和内输入轴依次连接,又与第二离合器、第二输入锥齿轮副和外输入轴依次连接;前进挡位齿轮副的主动齿轮分布于内、外输入轴上,从动齿轮分布于第一、二中间轴上;从动齿轮通过相应的同步器连接第一中间轴或第二中间轴;第一、二中间轴分别通过第一、二中间齿轮副输出动力至输出轴。能够最大限度的保留现有横置发动机,尽可能的实现动力总成装置,尤其是发动机的平台化、模块化设计;纵置变速器可以在现有横置变速器的基本上改型设计,减少开发周期及成本。
