Abstract
A hybrid drivetrain for a hybrid-driven vehicle, having a transmission, which can be shifted by shifting elements into different transmission steps, 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. The internal combustion engine shaft and a pinion shaft, which can be connected with respect to drive to the output shaft, are connectable via spur gearwheel sets, which can be shifted by means of shifting elements and which each form wheel levels, of which at least one hybrid wheel level is additionally connectable to the electric machine shaft.

A hybrid drivetrain for a hybrid-driven vehicle, comprising:
- a transmission, which is shiftable by shifting elements into different transmission steps 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 are connectable to the output shaft, are connectable via spur gearwheel sets, which is shiftable 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, and
- wherein at least one shifting element is arranged on the electric machine shaft, by which the hybrid wheel level is decoupled from the electric machine or coupled thereto.
