The present disclosure relates to an electric drive train (1, 1 ') comprising at least one first electric machine (2) and a second electric machine (3), at least one first output (4) and a second output (5), and at least one first planetary gear set (6) comprising three drivingly connected components (7, 8, 9) comprising a sun gear, a planet carrier and a ring gear. The first electric machine (2) and the second electric machine (3) are drivingly connected or connectable to the first output (4) and the second output (5) via a first planetary gear set (6). At least one of the first electric machine (2) and the second electric machine (3) is selectively drivingly connected or drivingly connectable to the same one of the three components (7, 8, 9) of the first planetary gear set (6) via at least two different gear ratios, and/or the same of the three components (7, 8, 9) of the first planetary gear set (6) is selectively drivingly connected or drivingly connectable to each of the first output (4) and the second output (5) via at least two different gear ratios. The present disclosure also relates to a method of operating an electric drive train (1, 1 ').
本公开涉及一种电动传动系(1、1'),包括至少一个第一电机(2)和第二电机(3),至少一个第一输出部(4)和第二输出部(5),以及至少一个第一行星齿轮组(6),至少一个第一行星齿轮组(6)包括三个驱动地连接的部件(7、8、9),包括太阳齿轮、行星架和齿圈。第一电机(2)和第二电机(3)经由第一行星齿轮组(6)与第一输出部(4)和第二输出部(5)驱动地连接或可连接。第一电机(2)和第二电机(3)中的至少一个经由至少两个不同的齿轮比与第一行星齿轮组(6)的三个部件(7、8、9)中的同一个选择性驱动地连接或驱动地可连接,和/或第一行星齿轮组(6)的三个部件(7、8、9)中的同一个经由至少两个不同的齿轮比与第一输出部(4)和第二输出部(5)中的每一个选择性驱动地连接或驱动地可连接。本公开还涉及一种操作电动传动系(1、1')的方法。
