The invention discloses a dual-clutch drive system. The system comprises a dual clutch transmission assembly and a power coupling rear axle assembly, wherein the dual clutch transmission assembly comprises a dual clutch assembly and a transmission assembly; the power coupling rear axle assembly comprises an axle housing, a coupling differential, a driving differential and a main reducer, wherein the coupling differential, the driving differential and the main reducer are positioned in the axle housing; the main reducer is used for transmitting power of a power output shaft to a half axle of the coupling differential, and the other half axle of the coupling differential is used for inputting second power; and the coupling differential transmits power to the driving differential through a power output gear, and the driving differential distributes the power to two axles of a vehicle. The dual-clutch drive system has the advantages of rapid gear shifting and high drive efficiency, and cancompactly integrate a power coupling device, the main reducer and the differentials into a rear axle of the vehicle, so that compactness of the drive system is greatly improved.

    本发明公开了一种双离合传动系统,包括双离合变速器总成和动力耦合型后桥总成;所述双离合变速器总成包括双离合器组件和变速器组件;所述动力耦合型后桥总成包括桥壳、位于所述桥壳内的耦合差速器、驱动差速器和主减速器;所述主减速器用于将动力输出轴的动力传递至耦合差速器的一个半轴,耦合差速器的另一个半轴用于输入第二动力;耦合差速器通过动力输出齿轮将动力传递至所述驱动差速器,并由驱动差速器将动力分配至车辆的两个轮轴;本发明的双离合传动系统具有换挡迅速、传动效率高的优点,可将动力耦合装置、主减速器和差速器紧凑集成于车辆后桥中,大大提高了传动系统的紧凑性。
