Abstract: In a motor vehicle, a combustion engine and electric machine are coupled with each other by a belt drive having a pulley and by a planetary gear train. The pulley is connected with a rotatable element, e.g. the sun gear of the planetary gear train. A second rotatable element, e.g. the ring gear of the planetary gear train, is connected with a brake disk. The brake disk extends radially farther outwardly than the pulley. In this way, the brake, for example two brake elements with a brake caliper support and brake shoes, can be arranged outside the pulley, resulting in small dimensions of the planetary gear train with the pulley.
