The invention relates to the technical field of hybrid electric vehicles, in particular to a power assembly of a hybrid electric vehicle and the hybrid electric vehicle. The power assembly of the hybrid electric vehicle comprises a power output mechanism and a speed change mechanism. The speed change mechanism comprises a speed change mechanism input shaft, a speed change mechanism output shaft, a third planet row, a fourth planet row, a B1 brake, a B2 brake and a C1 clutch. A gear ring of the third planet row is connected with a planet carrier of the fourth planet row, a sun gear of the third planet row is connected with a gearbox shell through the B1 brake, and a planet carrier of the third planet row is connected with a gear ring of the fourth planet row. A planet carrier of the third planet row and a gear ring of the fourth planet row are connected with the gearbox shell through the B2 brake. According to the power assembly, when the speed change mechanism is located at the third forward gear, the transmission efficiency of the whole speed change mechanism is close to 100%, and the energy loss of the speed change mechanism during power transmission can be remarkably reduced.

    本公开涉及混合动力汽车技术领域,尤其涉及一种混动汽车的动力总成以及混动汽车。该混动汽车的动力总成包括:动力输出机构和变速机构;所述变速机构包括变速机构输入轴、变速机构输出轴、第三行星排、第四行星排、B1制动器、B2制动器和C1离合器;所述第三行星排的齿圈与所述第四行星排的行星架连接,所述第三行星排的太阳轮通过所述B1制动器与变速箱壳体连接,所述第三行星排的行星架与所述第四行星排的齿圈连接,所述第三行星排的行星架和所述第四行星排的齿圈均通过所述B2制动器与所述变速箱壳体连接。该动力总成,该变速机构位于第三前进挡时,整个变速机构的传动效率接近100%,能够显著地降低变速机构在传递动力时的能量损失。
