摘要:
Electric vehicle drive arrangement having input and output shafts (EW, AW) and a change-speed transmission (G). The transmission (G) has two planetary gearsets (PS1, PS2) and first, second and third shifting elements (SE1, SE2, SE3) for engaging first, second and third gears (G1, G2, G3). The first planetary gearset (PS1) comprises a first sun shaft (SO1), a first ring gear shaft (HR1) and a first carrier shaft (ST1). The second planetary gearset (PS2) comprises a second sun shaft (SO2), a second ring gear shaft (HR2) and a second carrier shaft (ST2). The first carrier shaft (ST1) is connected to the second ring gear shaft (HR2), and the first sun shaft (SO1) forms the transmission input shaft (EW). The second carrier shaft (ST2) forms the transmission output shaft (AW). The first shifting element engages first gear, the second shifting element engages second gear and the third shifting element engages third gear.
