A hybrid drive for a motor vehicle, comprising:
- a first transmission input shaft for connectable to a first internal combustion engine;
- a second transmission input shaft, being coaxial to the first transmission input shaft, and connected to a first electric motor;
- a plurality of gear set planes for forward gears, the plurality of gear set planes including at least two gear set planes dedicated to the second transmission input shaft, and wherein the remaining gear set planes of the plurality of gear set planes are dedicated to the first transmission input shaft;
- a layshaft;
- a first gear shifting device and a second gear shifting device, wherein the first gear shifting device connects the first transmission input shaft and the second transmission input shaft in a first shifting setting and selects a transmission gear setting in a second shifting setting;
- and
- a transmission output shaft,
- wherein the first transmission input shaft is connectable to the first internal combustion engine directly or via a clutch,
- wherein the second gear shifting device is configured as a jaw clutch coupling and is disposed on one of the layshaft and the second input shaft, and
- wherein the transmission output shaft is disposed axially parallel to the first transmission input shaft.
