Abstract

Disclosed is an electric vehicle transmission (6″) comprising a drive input shaft (11), a drive output shaft (13), a first planetary gearset (15), and a second planetary gearset (16). The drive input shaft (11) is provided for connection to an electric machine (7), where each of the first planetary gearset (15) and the second planetary gearset (16) includes a first element (17, 18), a second element (19, 20) and a third element (21, 22), respectively. A first shifting element (A) and a second shifting element (B′) are provided, by the selective actuation of which the drive input shaft (11) can be connected to the drive output shaft (13) by means of the planetary gearsets (15, 16) by engaging a gear. Also disclosed is a drive module (2″) with such an electric vehicle transmission (6″) and a method for operating an electric vehicle transmission (6″).
