Abstract:
A drive assembly for a motor vehicle with a transmission that can be powershifted and comprises splitter and main transmissions, input and output shafts, loose and fixed gearwheels which form transmission gears, and shifting devices for coupling the loose gearwheels to at least one of the transmission shafts. The splitter transmission has first and second gear constants, and the inputs of the first and second gear constants can be driven by the outputs of two clutches whose inputs can be driven by a motor. One of the clutches is a frictional starting and shifting clutch and the other is a claw clutch, the inputs of the first and second gear constants can be driven alternatively by the output of the starting and shifting clutch, and that by way of the output of the claw clutch the input of only one of the gear constants can be driven.
