The invention relates to the technical field of hybrid electric vehicles, in particular to a power assembly of a hybrid electric vehicle and a 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, a C1 clutch and a C2 clutch. A gear ring of the third planet row is connected with a transmission shell through the B2 brake, and a sun gear of the third planet row and a sun gear of the fourth planet row are both connected with the transmission shell through the B1 brake. According to the power assembly of the hybrid electric vehicle, through the arrangement of the speed change mechanism, a plurality of output gears can be provided for the vehicle, the torque of the vehicle during low-speed running can be increased, and the running speed of the vehicle during high-speed running can be increased; the speed change mechanism can enable the third planet row and the fourth planet row to rotate synchronously when the C1 clutch and the C2 clutch are closed at the same time.

    本公开涉及混合动力汽车技术领域,尤其涉及一种混合动力汽车的动力总成以及车辆。该混合动力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、C1离合器和C2离合器;所述第三行星排的齿圈通过所述B2制动器与变速器壳体连接,所述第三行星排的太阳轮和所述第四行星排的太阳轮均通过所述B1制动器与变速器壳体连接。该混合动力汽车的动力总成,通过变速机构的设置,能够车辆提供多个输出挡位,既能提高车辆在低速行驶时的扭矩,又能提高车辆在高速行驶时的行驶速度;该变速机构能够在同时闭合C1离合器和C2离合器时,使第三行星排和第四行星排同步转动。
