A transmission unit for a hybrid motor vehicle, has a planetary gearing. The planetary gearing is fitted with a first planetary wheel set and a second planetary wheel set. The transmission unit also includes an electric machine, which is coupled with a component part of the planetary gearing, and a plurality of switching devices, each of which forming a brake or a clutch, and each being movable between an activated position and a deactivated position. The switching devices are operatively installed for switching various transmission ratios between an input, which can be coupled with an internal combustion engine, and an output, and/or between the electric machine and the output. No more than four switching devices are present for implementing at least two different transmission ratios in a drive state of the internal combustion engine, at least one transmission ratio in a drive state of the electric machine, and at least one transmission ratio in a recuperation state of the electric machine, as a result of their activated and deactivated positions.
