Drive path arrangement for combustion engine, having mechanical oscillation attenuation device with spring devices which engage at rotor carrier and primary part of clutch

摘要

The drive path arrangement includes a starter-generator system, a switchable clutch (10), and a mechanical oscillation attenuation device (60). The starter/generator system is an electric machine (8) with a rotor (36) driven by a crank shaft (14) of the combustion engine. The rotor is arranged on a rotor carrier (24) fastened on the crank shaft. A primary part (46) of the clutch is stored revolving at the rotor carrier over a bearing (40) which is arranged concentrically to the rotor, having an outside diameter smaller than the inside diameter of the rotor. The mechanical oscillation attenuation device comprises spring devices (62) which engage at the rotor carrier and the primary part of the clutch. The outside diameters of the primary part and a secondary part (48) of the clutch are smaller than the inside diameter of the rotor.
