The invention relates to a drive unit (1) for a drivetrain (2) of a hybrid motor vehicle. The drive unit has an internal combustion engine (3), a first electric machine (4), a second electric machine(7) which, with respect to its rotor (8), is arranged coaxially with respect to a rotational axis (6) of a rotor (5) of the first electric machine (4), a first transmission stage (9) arranged betweena drive component (11) which is or can be coupled in a rotationally fixed fashion to an output shaft (10) of the internal combustion engine (3), and a power shaft (12, 13) of the first electric machine (4) and/or of the second electric machine (7), and a transmission component unit (14) via which the power shaft (12, 13) of the respective electric machine (4, 7) is or can be coupled to wheel driveshafts (15a, 15b), wherein the drive component (11) of the internal combustion engine (3) is coupled to an intermediate gear unit (17) via a second transmission stage (16), the intermediate gear unit(17) has an integrated clutch (18) and is further connected to the wheel driveshafts (15a, 15b), namely depending on the position of this clutch (18), the internal combustion engine (3) is coupled tothe wheel driveshaft (15a, 15b) via at least the second transmission stage (16) or is decoupled from these wheel driveshafts (15a, 15b).

    本发明涉及一种用于混合动力车辆的传动系(2)的驱动单元(1),其具有内燃机(3)、第一电机(4)、关于其转子(8)与第一电机(4)的转子(5)的转动轴线(6)同轴布置的第二电机(7)、布置在抗相对转动地与内燃机(3)的输出轴(10)耦合/能耦合的驱动组成部分(11)与第一电机(4)的和/或第二电机(7)的传动轴(12、13)之间的第一传动级(9)、以及传动装置部分单元(14),各自的电机(4、7)的传动轴(12、13)经由该传动装置部分单元与车轮驱动轴(15a、15b)耦合/能耦合,其中,内燃机(3)的驱动组成部分(11)经由第二传动级(16)与副轴单元(17)耦合,其中,副轴单元(17)具有被整合的离合器(18),并且如下这样地进一步与车轮驱动轴(15a、15b)连接,即,依赖于该离合器(18)的位置地,让内燃机(3)至少经由第二传动级(16)与车轮驱动轴(15a、15b)耦合或与这些车轮驱动轴(15a、15b)脱耦。
