Hybrid drive train for a hybrid-driven motor vehicle

A hybrid drivetrain for a hybrid-driven vehicle, comprising:

• a transmission, which can be shifted by shifting elements into different transmission steps, in particular a manual shift transmission, and which is connectable via an internal combustion engine shaft to an internal combustion engine, via an electric machine shaft to an electric machine, and via an output shaft to at least one vehicle axis, wherein the internal combustion engine shaft and a pinion shaft, which can be connected to the output shaft, are connectable via spur gearwheel sets, which can be shifted by the shifting elements and which each form wheel levels, of which at least one hybrid wheel level is additionally connectable to the electric machine shaft, wherein at least one shifting element is arranged in particular on the electric machine shaft, by which the hybrid wheel level can be decoupled from the electric machine or can be connected thereto.
