The invention relates to an axle drive train (8), comprising a planetary stage (14), a first output shaft (13) and a second output shaft (11), which are provided for connection to drive wheels (6, 7) of a drive axle (3) of a motor vehicle, and a drive shaft (9), which is provided for coupling to a drive device. The planetary stage (14) has a sun gear (19), a ring gear (21) and a planet carrier (20) in which at least one planet gear (22) is rotatably mounted, the at least one planet gear (22) being in engagement with each of the sun gear (19) and the ring gear (21). The planetary stage (14) has a static transmission ratio of less than-1, the sun gear (19) of the planetary stage (14) being connected in a rotationally fixed manner to the drive shaft (9) and the planet carrier (20) being connected in a rotationally fixed manner to the first output shaft (12) which is coupled via a first intermediate transmission (16) to the first output shaft (13) and the ring gear (21) being connected in a rotationally fixed manner to the second output shaft (10), the second output shaft is coupled to the second output shaft (11) via a second intermediate transmission (15). The transmission ratio relationship of the intermediate transmissions (15, 16) is coordinated in such a way that a symmetrical torque distribution occurs from the drive shaft (9) to the output shaft (11, 13) in conjunction with the static transmission ratio of the planetary stage (14).

    本发明涉及车桥传动系统(8),其包括行星级(14)、被设置成用于与机动车驱动桥(3)的驱动车轮(6、7)连接的第一从动轴(13)和第二从动轴(11)、以及被设置成用于与驱动装置耦联的驱动轴(9)。行星级(14)具有太阳轮(19)、齿圈(21)和行星架(20),在行星架中以能转动的方式支承有至少一个行星轮(22),其中,至少一个行星轮(22)与太阳轮(19)和齿圈(21)分别处于啮合中。行星级(14)具有小于‑1的静态传动比,其中,行星级(14)的太阳轮(19)抗相对转动地与驱动轴(9)连接,而行星架(20)抗相对转动地与第一输出轴(12)处于连接中,第一输出轴经由第一中间传动部(16)与第一从动轴(13)耦联,并且齿圈(21)与第二输出轴(10)抗相对转动地连接,第二输出轴经由第二中间传动部(15)与第二从动轴(11)耦联。中间传动部(15、16)的传动比关系被如下这样地相互协调,即,使得与行星级(14)的静态传动比相结合地出现从驱动轴(9)到从动轴(11、13)的对称的扭矩分配。
