Abstract

An electric drive system has a group transmission with a main group and a range group with a planetary gear set. First and second input shafts of the main group are respectively coupled with first and second electric engines. An output shaft of the main group is coupled with a first element of the planetary gear set and a second element of the planetary gear set is coupled with an output drive shaft of the group transmission. Two idler wheels are disposed coaxially to the first input shaft and two further idler wheels are disposed coaxially to the second input shaft. The first and second input shafts are coupled with the output shaft via two fixed gears. A first fixed gear engages with the first and third idler wheels and a second fixed gear engages with the second and fourth idler wheels.
