Publication number: 20170050506Abstract: The invention relates to a torque transmission device that is to be arranged in a drive train of a hybrid vehicle having an internal combustion engine, a transmission and an electric machine, the electric machine being arranged in the torque transmission device. The torque transmission device includes a disconnect clutch with clutch actuation, for decoupling the internal combustion engine from the transmission, and a primary torsional vibration damper on the crankshaft side. The invention has a secondary torsional vibration damper arranged on the transmission side, radially and axially inside the rotor and directly on the transmission-side output flange of the torque transmission device. This allows the installation space for the crankshaft-side primary torsional vibration damper to be increased, such that the damper can be optimally designed.Type: ApplicationFiled: May 5, 2015Publication date: February 23, 2017Applicant: Schaeffler Technologies AG & Co.
