Abstract

Disclosed is a starting device for a transmission. The starting device includes a drive input shaft provided for coupling the starting device to a drive engine connected upstream from the transmission. An output shaft is configured to connect the starting device to a gearset of the transmission. The drive input shaft and the output shaft can be connected rotationally fixed to one another by means of a first shifting element. An electric machine is provided whose rotor is connected to an intermediate shaft. The intermediate shaft is coupled to the output shaft by way of at least one gear step. In order to realize integration of the upstream drive engine and the electric machine, a second shifting element is also provided which, when actuated, forms a rotationally fixed connection between the intermediate shaft and the drive input shaft.
