Claim:
A drive assembly for a motor vehicle with a group transmission that can be powershifted, the group transmission comprising a splitter transmission (SG) and a main transmission (HG), the drive assembly comprising: the group transmission (SG, HG) comprising a transmission input shaft ( 5 ), at least one other transmission shaft ( 6 , 31 , 32 ) and a transmission output shaft ( 8 ), loose gearwheels and fixed gearwheels, for form transmission gears, being arranged on the transmission shafts ( 5 , 6 , 31 , 32 ), shifting devices ( 48 , 49 , 50 ) for coupling the loose gearwheels ( 43 , 44 , 45 , 46 , 47 ) in a rotationally fixed manner to at least one of the transmission shafts ( 5 , 6 ), the splitter transmission (SG) having at least a first gear constant (K 1 ) and a second gear constant (K 2 ), input sides of the first and the second gear constants (K 1 , K 2 ) being drivable by output sides of a clutch device ( 1 ) comprising two clutches, input sides of the two clutches being drivable by a drive motor, one of the two clutches of the clutch device ( 1 ) being a frictional starting and shifting clutch ( 1 a ) and the other of the two clutches being a positively interlocking claw clutch ( 1 b , 1 c ), the input sides of the first and the second gear constants (K 1 , K 2 ) being alternatively drivable by the output side of the starting and shifting clutch ( 1 a ), and the input side of only one of the gear constants (K 1 ) being drivable by the output side of the claw clutch ( 1 b ; 1 c ).
