    • A hybrid powertrain unit comprises an internal-combustion engine (E), and a gearbox device (C) with a primary shaft (3) that can be connected to the shaft (5) of the internal-combustion engine (E) via a clutch device (6). The gearbox device (C) comprises a secondary shaft (7) with an output pinion (9) meshing with a first crown wheel (10) of a differential (D), the casing (11) of which is rigidly connected to the casing (2) of the gearbox device (C). The unit further comprises an electric machine (M) adapted to function both as electric motor and as electric generator, having a shaft (16) connected by means of a transmission to a second crown wheel (19) of the differential (D). In the connecting transmission, arranged between the shaft (16) of the electric machine (M) and the second crown wheel (19) of the differential (D) is an engagement device (25) that can be driven via an electronic-control actuator. The shaft (16) of the electric machine (M) is connected to the shaft (5) of the internal-combustion engine (E), on the side opposite to the gearbox device by means of a belt transmission that controls auxiliary devices (CO, VS) of the motor vehicle, which are mounted coaxially with respect to the electric machine.
    • 混合动力总成单元包括内燃机(E)和具有主轴(3)的齿轮箱装置(C),所述主轴(3)能够通过离合器连接到内燃机(E)的轴(5) 装置(6)。 齿轮箱装置(C)包括具有与差速器(D)的第一冠轮(10)啮合的输出小齿轮(9)的副轴(7),其壳体(11)刚性地连接到壳体 2)的齿轮箱装置(C)。 该单元还包括适于作为电动机和发电机起作用的电机(M),其具有通过变速器连接到差速器(D)的第二冠轮(19)的轴(16)。 在电动机(M)的轴(16)和差速器(D)的第二冠轮(19)之间的连接变速器中,是能够通过电动执行机构驱动的接合装置(25) 。 电机(M)的轴(16)通过皮带传动装置连接到内燃机(E)的轴(5),与齿轮箱装置相反的一侧,控制辅助装置(CO ,VS),其相对于电机同轴安装。
