Patent ID: 8684875

Claim:
A device for a drive-train of a hybrid vehicle, the device comprising: a planetary gear set ( 8 ) comprising three elements, the three elements comprising a carrier ( 9 ), a sun gear ( 10 ) and a ring gear ( 11 ); a first element, of the three elements ( 9 , 10 , 11 ) of the planetary gear set, forming a fixed connection of a first transmission input shaft ( 6 ) with a first partial transmission ( 4 ) of a transmission ( 3 ), and a second element, of the three elements ( 9 , 10 , 11 ) of the planetary gear set, forming a fixed connection with an electric machine ( 2 ) of a hybrid drive; a first shifting element ( 12 ) having a first shift position (A) and a second shift position (B); in the first shift position (A) of the first shifting element ( 12 ), a third element of the three elements ( 9 , 10 , 11 ) of the planetary gear set is connected to a second transmission input shaft ( 7 ) of a second partial transmission ( 5 ) of the transmission, and an internal combustion engine ( 1 ) of the hybrid drive being couplable to the second transmission input shaft ( 7 ); in the second shift position (B) of the first shifting element ( 12 ), the third element of the three elements ( 9 , 10 , 11 ) of the planetary gear being connected to one of a housing and a stator; a second shifting element ( 13 ) being engageable and disengageable; and when the second shifting element ( 13 ) is engaged, the first and the second transmission input shafts ( 6 , 7 ) of the first and the second partial transmissions ( 4 , 5 ) are coupled to one another, and when the second shifting element ( 13 ) is disengaged, the first and the second transmission input shafts ( 6 , 7 ) of the first and the second partial transmissions ( 4 , 5 ) are separated from one another.
