Abstract

A hybrid drive device includes an internal combustion engine, an electric motor having a rotor, and a gearbox having an input planetary gearing with a main axis of rotation. The internal combustion engine is connected to the input planetary gearing via a disconnect clutch. The input planetary gearing has exactly two planetary gear sets each with three elements. The third element is connected to the sixth element to conjointly rotate and the second element is connected to the fifth element to conjointly rotate. The rotor is coupled to the third element such that torque originating from the rotor is introduced into the gearbox via the third element and the sixth element. The gearbox has a third planetary gear set with three further elements. The second element is connected to the seventh element to conjointly rotate and the eighth element is connected to a driven gear to conjointly rotate.
