  • Patent number: 10766350
    Abstract: A transmission for a motor vehicle having an input shaft, an output shaft, a plurality of 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. An actuating element of one of the plurality of shift elements is arranged, at least partially, radially within an element of the spur gear drive or 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 orthogonal to an axis of rotation of the input shaft.
