Abstract

A transmission for a motor vehicle having an input shaft, an output shaft, first, second, and third planetary gear sets, a plurality of shift elements, and an electric machine arranged axially parallel to the input shaft and operatively connected to the input shaft with a constant transmission ratio via a spur gear drive or a flexible traction drive mechanism. Various gear steps are formable between the input shaft and the output shaft through the planetary gear sets by selectively engaging shift elements of the plurality of shift elements. Elements of the third planetary gear set are arranged, at least partially, radially within an element of the spur gear drive or of the flexible traction drive mechanism arranged coaxially to the input shaft, and together with the spur gear drive or the flexible traction drive mechanism in a plane oriented orthogonally to the axis of rotation of the input shaft.
