The invention relates to a dual-mode power coupling system with an input shunting mode and an output shunting mode, and belongs to the technical field of hybrid power driving. The dual-mode power coupling system comprises a first power source, a second power source, a third power source, a planetary gear mechanism, a fixed gear train, a synchronizer and a brake, wherein the fixed gear train comprises first to seventh gears; and the planetary gear mechanism comprises a sun gear, an inner gear ring, a planet gear and a planet carrier. Two hybrid driving modes of input power shunting and output power shunting can be achieved only through one planetary gear mechanism, only one synchronizer and one brake need to be configured, and the structure is simple; multiple working modes can be achieved, the working modes are switched by controlling the synchronizer and the brake, the synchronizer is combined with the sixth gear or the seventh gear, conversion between the input shunting mode and the output shunting mode is completed, and the control process is simplified; and the system is high in efficiency, easy in spatial arrangement and high in working reliability.

    本发明涉及一种具有输入分流及输出分流模式的双模功率耦合系统,属于混合动力驱动技术领域。包括第一动力源、第二动力源、第三动力源、行星齿轮机构、固定齿轮系、同步器和制动器;固定齿轮系包括第一至第七齿轮;行星齿轮机构包括太阳轮、内齿圈、行星轮和与行星架。只通过一个行星齿轮机构即可实现输入功率分流及输出功率分流两种混合驱动模式,只需要配置一个同步器、一个制动器,结构简单;能实现多种工作模式,通过控制同步器和制动器切换工作模式,通过同步器与第六齿轮或第七齿轮结合,完成输入分流与输出分流模式的转换,简化控制过程;系统效率高,空间布置容易,工作可靠性高。
