1. A drive system for a vehicle, comprising:
an internal combustion engine (92), the internal combustion engine (92) being switchable between operating modes of different performance; a torsional vibration damping arrangement (10), the torsional vibration damping arrangement (10) comprising:
(i) an input region (12) configured to be driven in rotation, and(ii) an output region (14), a first torque transmission path (20) being provided between the input region (12) and output region (14); and a second torque transmission path (22) being provided parallel thereto; a coupling arrangement (24) configured to superpose the torques transmitted via the first and second torque transmission paths (20, 22); wherein the coupling arrangement comprises a planetary gear arrangement (52), including a first and second planet gear; a phase shifter arrangement (26), provided in at least one torque transmission path (20), configured to generate a phase shift of rotational irregularities transmitted via the one torque transmission path (20) in relation to the rotational irregularities transmitted via the other torque transmission path (22); wherein the planetary gear arrangement includes: a first ring gear arrangement in meshing engagement with the first planet gear and connected to the first torque transmission path, and a second ring gear arrangement in meshing engagement with the second planet pear and connected to the output region. |
