Manual shift transmission of a hybrid drive for a motor vehicle

The shift gearbox (1.1) has two input shafts (GE1,GE2) and a common output shaft (GA), where the former input shaft is connected with a drive shaft (4) of an internal combustion engine (VM) and is brought into drive connection with the output shaft by a group of selectively switchable gear sets (G1,G2,G3,G4,G5). The latter input shaft stands in drive connection with a rotor (8) as an engine and as a generator operated electric machine (EM). The former input shaft is centrally arranged, and the latter input shaft is formed as a hollow shaft and is coaxially arranged over the former input shaft.
