Hybrid drive of a motor vehicle

A hybrid drive of a motor vehicle, the hybrid drive comprising:

• an internal combustion engine having a drive shaft;
• at least one electric machine having a rotor;
• a manual transmission having first and second input shafts and a common output shaft, the first input shaft being connectable to the drive shaft of the internal combustion engine and the second input shaft being continuously connected to and driven by the rotor of the electric machine,
• the first and the second input shafts being coaxially aligned in series, and the output shaft being hollow and coaxially aligned with the first and the second input shafts,
• one of the first and the second input shafts passing through the output shaft;
• and
• first and second planetary gear sets being coaxially aligned with one another and the first and the second input shafts, each of the first planetary gear set and the second planetary gear set comprising a sun gear, a ring gear and a planetary carrier, the ring gears of the first and the second planetary gear sets are input elements, and the planetary carriers of the first and the second planetary gear sets are output elements,
• the internal combustion engine is connectable to either the second input shaft via a first shift element, or to the ring gear of the first planetary gear set, via a second shift element, and
• the planetary carriers of the first and the second planetary gear sets being continuously connected to each other and the output shaft, and the sun gear of the first planetary gear set is continuously connected to a housing.
