变速器及操作该变速器的方法
摘要：
本发明涉及一种特别用于车辆的变速器(1)，其包括传动系，传动系具有带有主驱动轴(16)的主驱动器，并且变速器包括拉维娜行星齿轮组(2)，其具有双行星齿轮系，该双行星齿轮系带有两个太阳齿轮轴(10，13)、一个行星架轴(18)和至少一个齿圈轴(12)，以及变速器包括设置为减速齿轮的上游单级行星齿轮组(3)，该单级行星齿轮组包括太阳齿轮(5a)，行星架(8a)和齿圈(6a)。单级行星齿轮组(2)的所述齿轮元件中的第一个、特别是太阳齿轮(5a)设计为固定到壳体上。根据本发明，所述拉维娜行星齿轮组(2)的至少一个第一元件优选永久性地驱动连接到次级驱动器(21)，该次级驱动器特别优选地由电动机构成。
摘要（英）：

A transmission includes a drive train having a primary drive with a primary drive shaft (16), particularly for a vehicle, and includes a Ravigneaux planetary gearset (2) which has a double planetary gear with two sun gear shafts (10, 13), one planetary carrier shaft (18) and at least one ring gear shaft (12), as well as an upstream single planetary gearset (3) which is designed as a reduction gearing and includes the gear elements of sun gear (5a), planetary carrier (8a) and ring gear (6a). A first of the gear elements of the single planetary gear set (2), particularly the sun gear (5a), is designed to be fixed to a housing. At least one first element of the Ravigneaux planetary gear set (2) is drive-connected, preferably permanently, to a secondary drive (21) which is particularly preferred to be in the form of an electrical machine.
