The hybrid power coupling system comprises an engine, a first motor, a planet row, a brake, a first clutch, an input shaft and a first intermediate shaft, the engine and the first motor are both connected to the input shaft, and the input shaft is in transmission connection with the first intermediate shaft through a first gear pair; the sun gear is idly sleeved on the first intermediate shaft; the brake is used for braking the sun gear; the gear ring is fixedly arranged on the first intermediate shaft, any two structures of the sun gear, the planet carrier and the gear ring are connected through a first clutch, and the planet carrier is meshed with an output gear ring of the differential mechanism; the first clutch and the brake are controlled to switch the two speed ratios of the planet row, the engine and the first motor can decelerate and output at the two speed ratios, and the dynamic property and the economical efficiency are good; the planet row is connected to the first intermediate shaft, so that the planet row is prevented from being coaxial with the engine or the first motor, the axial length of the hybrid power coupling system can be reduced, and space saving, light weight and cost reduction are facilitated.
本发明混合动力耦合系统及车辆,包括发动机、第一电机、行星排、制动器、第一离合器、输入轴和第一中间轴,发动机和第一电机均连接于输入轴,输入轴通过第一齿轮副传动连接于第一中间轴;太阳轮空套于第一中间轴上,制动器用于制动太阳轮;齿圈固设于第一中间轴上,太阳轮、行星架和齿圈中的任意两个结构之间通过第一离合器连接,行星架与差速器的输出齿圈啮合;控制第一离合器和制动器切换行星排的两种速比,发动机和第一电机均能以两种速比减速输出,动力性和经济性好;行星排连接在第一中间轴,避免行星排与发动机或第一电机同轴,从而能够减小混合动力耦合系统的轴向长度,有利于节省空间、轻量化和降低成本。
