The invention provides a dual-mode hybrid power transmission device, which relates to the technical field of hybrid power automobile transmission, and comprises a controller, and a planetary gear row group, two motors and a torque transmission device which are coaxially arranged, the torque transmission device comprises a first clutch, a second clutch, a first brake and a second brake, and the power dividing mechanism composed of the two planetary gear rows and the torque transmission device can provide a dual-mode power dividing mode and four pure fuel oil modes with fixed speed ratios. The double modes are divided into an input type power split mode and a combined type power split mode, and four fixed speed ratios of the pure fuel mode are two deceleration gears, a direct gear and an overgear respectively. Compared with single-mode power splitting, on one hand, the speed ratio range of the hybrid power transmission device can be expanded, on the other hand, the torque and power of the motor can be reduced, and four pure fuel oil driving modes can be provided to meet the requirements of more different working conditions.

    本发明提供一种双模式混合动力传动装置,涉及混合动力汽车传动技术领域,包括控制器、以及同轴布置的行星齿轮排组、两台电机、扭矩传递装置;所述扭矩传递装置包括第一离合器、第二离合器、第一制动器和第二制动器,由两个行星齿轮排和扭矩传递装置组成的功率分流机构可以提供双模式的功率分流模式和四个固定速比的纯燃油模式,双模式分为输入式功率分流模式、复合式功率分流模式,纯燃油模式的四个固定速比分别为两个减速档、一个直接档和一个超速档。本发明与单模式功率分流相比,一方面可扩大混合动力传动装置的速比范围,另一方面可以减少电机的转矩和功率,还可以提供四个纯燃油行驶模式来满足更多不同工况的要求。
