1. A hybrid drive of a motor vehicle, which has an automated manual transmission (2.1-2.20) derived from a double clutch transmission (2.0) having two coaxially disposed input shafts (GE1, GE2) and a common output shaft (GA), in which one of the two input shafts (GE1; GE2) of the hybrid drive is connectable to a drive shaft (3) of an internal combustion engine (VM) and is drivingly connectable with the output shaft (GA) via an associated first group of selectively shiftable gear wheel sets (5, 7, 9, 10; 6, 8), and the other input shaft (GE2; GE1) of the hybrid drive is in drive connection with a rotor (25) of an electric machine (EM) that is operable as a motor and as a generator, and is drivingly connectable with the output shaft (GA) via an assigned second group of selectively shiftable gear wheel sets (6, 8; 5, 7, 9, 10), the gear wheel sets (5-10) are disposed, in each case, between one of the two input shafts (GE1, GE2) and one of two countershafts (VG1, VG2) that are each in drive connection with the output shaft (GA) via an output constant (KA1, KA2), each gear wheel set (5-10) comprises a fixed gear (11-13) that is disposed on the associated input shaft (GE1, GE2) in a rotationally fixed manner and an idler gear (14-19) that is disposed on the respective countershaft (VG1, VG2), per input shaft (GE1, GE2) at least the two gear wheel sets (7, 9; 6, 8), internal to the transmission, with idler gears (16, 18; 15, 17) disposed on different countershafts (VG1, VG2), are disposed in a common radial plane with use of a common fixed gear (12, 13), at least two idler gears (15, 16), disposed on one of the two countershafts (VG1, VG2) of two gear wheel sets (6, 7), internal to the transmission, assigned to the two different input shafts (GE1, GE2), is couplable together via a winding-path shift element (SW), and the two output constants (KA1, KA2) are disposed in a common radial plane and mesh with a common output gear (22) disposed on the output shaft (GA). |
