Abstract
A device for a drive-train of a hybrid vehicle comprising a planetary gearset having three elements which comprise a carrier, a sun gear and a ring gear. A first elements serves as a fixed connection of a first input shaft of a first partial transmission of a transmission. A second of the elements serves as a fixed connection of a hybrid drive electric machine. A first shifting element connects, in a first position thereof, a third of the elements to a second input shaft of a second partial transmission, to which a hybrid drive combustion engine can be coupled. The first shifting element, when in a second position, connects the third of the elements to the housing or the stator. A second shifting element, when engaged, couples the two input shafts of the two partial transmissions with one another and, when disengaged, separates the two input shafts from one another.
