Abstract:
A motor vehicle transmission including an interface to a drive unit, a drive shaft, an output shaft coaxial to the drive shaft, a differential transmission paraxial to the drive shaft, a device for forming gear ratios between the drive and output shafts, and an electric motor with a fixed stator and a rotatable rotor. The output shaft is connected with the differential transmission by a chain drive and a downstream gear set coaxial to the differential transmission. The electric motor is at an axial end of the transmission where the interface to the drive unit is formed. The rotor is connected with the drive shaft. The chain drive is axially between the differential transmission and the downstream gear set or the downstream gear set is axially between the chain drive and the differential transmission, and the chain drive is axially between the electric motor and the downstream gear set.
