The invention relates to a power system considering both an engine longitudinally-arranged rear-drive car and a four-drive car. A rear-drive car type and a four-drive car type each comprise an engine, a transmission, a rear transmission shaft, a rear main speed reducer, a rear driving shaft and a rear ball cage universal joint. When a four-wheel-drive vehicle type is matched, a front driving shaft, a front main speed reducer, a front transmission shaft, a transfer case and a front ball cage universal joint are additionally arranged on the basis of an original rear-wheel-drive vehicle type; the vehicle is provided with the power system. According to the power system considering the longitudinal rear-drive car and the four-drive car, two car types and a rear-drive car type can be taken into consideration at the same time, development is completed on the basis, when the four-drive car type needs to be developed, assembly parts of the original rear-drive car type can be borrowed to the maximum extent, only a necessary transmission system of the four-drive car type is added, an original arrangement structure is not affected, and the engine, the engine and the rear-drive car type are arranged on the power system. The design boundaries of the transmission, the main speed reducer and the suspension are basically unchanged, the change on the rear-drive vehicle type is small, the universality is high, the cost is low, and the period is short.

    本发明涉及一种兼顾发动机纵置后驱轿车和四驱轿车的动力系统,后驱车型和四驱车型均包括发动机,变速器,后传动轴,后主减速器,后驱动轴,后球笼万向节;当匹配四驱车型时,在原后驱车型基础上新增前驱动轴、前主减速器、前传动轴、分动器、前球笼万向节;车辆设置有所述的动力系统;本发明所述的兼顾纵置后驱轿车和四驱轿车的动力系统能同时兼顾两种车型,后驱车型作为基础开发完成,需要开发四驱车型时,可以最大限度借用原后驱车型的总成零件,仅增加四驱车型必要的传动系统,而原布置结构不受影响,发动机,变速器、主减速器、悬架设计边界基本不变,对后驱车型的改动小,通用性高,成本低,周期短。
