Double clutch transmission

The transmission (16) has an input shaft (24) i.e. solid shaft, another input shaft (26) i.e. hollow shaft, and countershafts (32, 34) connected with each other by fixed wheels (48, 50) and loose wheels (56, 58, 66, 68) for obtaining seven forward gear stages (1-7) and a reverse gear stage (R). The fixed wheels are connected with one of the input shafts. The loose wheels are rotatably mounted at the countershafts and engaged with the fixed wheels. An electrical machine (90) e.g. electric motor, is connected at the loose wheels by a connecting clutch (94).
