Abstract

The present invention relates to a hybrid drive train for a motor vehicle, comprising a clutch arrangement having a first rotatable clutch part and a second rotatable clutch part, which clutch parts can be separated from one another and which can be connected to one another, and comprising an electrical machine which is arranged concentrically with respect to the first clutch part and has a rotor, wherein the rotor is connected with the first clutch part and comprises a plurality of magnetic flux influencing portions, the magnetic flux influencing portions being arranged distributed over the circumference of the rotor with a predetermined rotor pitch. Here, the first clutch part comprises a shaft toothing that is adapted to the rotor pitch.
