Patent ID: 8585522

Claim:
A drive train of a hybrid vehicle comprising: a drive assembly ( 3 ) comprising a combustion engine ( 1 ) and an electric machine ( 2 ); a transmission ( 5 ) comprising at least first and second partial transmissions ( 6 , 7 ) being located between the drive assembly ( 3 ) and an output ( 4 ); the electric machine ( 2 ) being connected, via a planetary transmission ( 10 ), to an input shaft ( 9 ) of the first partial transmission ( 7 ) and an input shaft ( 8 ) of the second partial transmission ( 6 ) which is arranged parallel to the first partial transmission ( 7 ); the combustion engine ( 1 ) being connectable, via a separation clutch ( 11 ), to the input shaft ( 8 ) of the second partial transmission ( 6 ), and the combustion engine ( 1 ), when the separation clutch ( 11 ) is engaged, being connected to the input shaft ( 9 ) of the first partial transmission ( 7 ), via the planetary transmission ( 10 ); a bridging shift element ( 12 ) interacting with the planetary transmission ( 10 ) such that the bridging shift element is only either fully engaged or fully disengaged: when the bridging shift element ( 12 ) is engaged, a torsionally fixed connection exists between the electric machine ( 2 ), the input shaft ( 9 ) of the first partial transmission ( 7 ) and the input shaft ( 8 ) of the second partial transmission ( 6 ) such that they all rotate at a same rotational speed, and when the bridging shift element ( 12 ) is disengaged, the torsionally fixed connection between the electric machine ( 2 ), the input shaft ( 9 ) of the first partial transmission ( 7 ) and the input shaft ( 8 ) of the second partial transmission ( 6 ) is interrupted so that they can rotate at different rotational speeds.
