The invention discloses a vehicle four-wheel drive oil-electricity hybrid power system which comprises a DSP controller, the DSP controller is in driving connection with a front axle oil-electricity hybrid power mechanism used for driving front wheels and a rear axle electric power mechanism used for driving rear wheels, the DSP controller is further connected with a power battery, and the front axle oil-electricity hybrid power mechanism comprises a fuel engine. The fuel engine is in driving connection with a single clutch, a generator/motor, a double clutch, a two-gear gearbox, a front speed reducer and a front axle differential mechanism, the rear axle electric power mechanism comprises a motor, and the motor is in driving connection with a rear speed reducer and a rear wheel differential mechanism. According to the front-axle oil-electricity hybrid power mechanism adopted by the power system, the gearbox can adopt a relatively simple two-gear gearbox to cope with direct driving of medium-speed and high-speed engine power to the vehicle, and due to the fact that the number of gears of the gearbox is small, the axial size of the gearbox can be very small, and arrangement of a cabin is facilitated.
本发明公开了一种车用四轮驱动油电混合动力系统,包括DSP控制器,DSP控制器驱动连接有用于驱动前轮的前轴油电混合动力机构和用于驱动后轮的后轴电力动力机构,DSP控制器还连接有动力电池,其中前轴油电混合动力机构包括燃油发动机,燃油发动机驱动连接有单离合器、发电/电动机、双离合器、二挡变速箱、前减速器和前轴差速器,后轴电力动力机构包括电动机,电动机驱动连接有后减速器和后轮差速器。本发明动力系统采用的前轴油电混合动力机构,其中的变速箱可以采用相对简单的二档变速箱,来应对中高速的发动机动力直接驱动车辆,而且由于变速箱档位数少,也使得变速箱的轴向尺寸可以很小,便利机舱布置。
