The first plurality of clutch plates is drivingly connected to the first spline. The input has a second outer circumferential surface with a second spline. The second plurality of clutch plates is drivingly connected to the second spline. The spring element is for compressing the clutch plates to transmit a clutch torque. The first torsion damper is arranged in a first torque path between the input and an engine. The second torsion damper is arranged in a second torque path between the rotor carrier and a multi-speed transmission.

  • Patent number: 10940749
    Abstract: A method of operating a vehicle having a hybrid drive, a transmission with shift elements, a drive output with a brake, a main transmission with input shafts, an output shaft and planetary gear sets (PG1, PG2). The main transmission has five gear planes. One shift element can connect a gear plane to an element of gear set (PG1) adjoining the main transmission. Another shift element couples a further element of gear set (PG1) either to the output shaft or a housing. An electric machine is permanently connected to an element of gear set (PG2). If, while driving with a transmission gear engaged, the drive output brake is engaged for a full brake application, a shift element of the transmission is first relieved by the electric machine and/or a brake assigned to one of the input shafts and then subsequently disengaged to decouple the combustion engine from the drive output.
