The invention discloses a split-flow type hybrid power device of an automobile. Comprising an engine, a planetary gear mechanism, a first motor, a second motor, an input shaft connected with a planet carrier of the planetary gear mechanism, a two-gear engaging mechanism connected with a gear ring of the planetary gear mechanism, a one-way brake connected with the input shaft and used for braking the input shaft, and an output gear connected with the gear ring of the planetary gear mechanism. The rotor shaft is connected with a rotor of the first motor, the intermediate gear is connected with a rotor of the second motor, the rotor shaft is connected with a sun gear of the planetary gear mechanism and the two-gear engaging mechanism, and the intermediate gear and the output gear are meshed with the primary driven gear. According to the split-flow type hybrid power device of the automobile, the one-way brake which is low in cost and simple in structure is adopted to be matched with the two-gear engaging mechanism, the problem of low electric power flow efficiency cannot occur during medium-speed and high-speed driving, the problem of high cost caused by the arrangement of a clutch cannot occur, and therefore the cost can be reduced.

    本发明公开了一种汽车分流式混合动力装置,包括发动机、行星齿轮机构、第一电机、第二电机、与行星齿轮机构的行星架连接的输入轴、与行星齿轮机构的齿圈连接的两挡挂挡机构、与输入轴连接且用于制动输入轴的单向制动器、与行星齿轮机构的齿圈连接的输出齿轮、与第一电机的转子连接的转子轴和与第二电机的转子连接的中间齿轮,转子轴与行星齿轮机构的太阳轮和两挡挂挡机构连接,中间齿轮和输出齿轮与一级被动齿轮相啮合。本发明的汽车分流式混合动力装置,采用低成本、结构简单的单向制动器与同两挡挂挡机构相配合,在中高速行驶时,不会出现电功率流效率低的问题,而且也不会出现设置离合器而导致成本高的问题,从而可以降低成本。
