摘要： A hybrid-electric powertrain includes an internal combustion engine, a transmission, and an electric machine, where the electric machine is connected to the transmission for transmitting torque. The transmission has a transmission housing, within which there is disposed an output-side gear set assembly, and also a transmission housing cover disposed on an output side of the transmission as seen in an axial direction. The electric machine has a stator, a rotor, a rotor shaft connected to the rotor for conjoint rotation, and an electric machine housing. In addition, the electric machine has a connection housing for connecting the electric machine to the transmission housing. The rotor shaft of the electric machine is disposed parallel to a transmission input shaft of the transmission.

摘要： 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.

摘要： A group transmission device includes a main transmission which has a main shaft, a countershaft and a spur gear pair which includes a first spur gear arranged coaxially and axially overlapping with the main shaft and a second spur gear arranged coaxially and axially overlapping with the countershaft. A range group has a first shaft non-rotationally connected to the main shaft, a second shaft non-rotationally connected to a transmission output shaft, a third shaft and a blocking switching unit. A first switching unit non-rotationally connects the third shaft to a housing. A second switching unit has an axially shiftable switching element and non-rotationally connects the third shaft to the first spur gear. The main shaft is coupled non-rotationally to a transmission input shaft. A third switching unit has an axially shiftable further switching element and non-rotationally connects the first spur gear to the first shaft of the range group.

摘要： A group transmission device includes an upshift assembly with a first transmission element, a second transmission element and a third transmission element. A downshift assembly has a first transmission element, a second transmission element and a third transmission element. A main shaft is arranged coaxially to the upshift assembly and a layshaft is arranged parallel to the main shaft. A first idler gear is arranged coaxially to the main shaft and axially between the upshift assembly and the downshift assembly and is connectable to the main shaft for conjoint rotation by a first shift unit. The first idler gear is connectable to the third transmission element of the downshift assembly for conjoint rotation by a second shift unit.
