Abstract

A crankshaft 2 of an internal combustion engine, which is supported with freedom to rotate around an axis of rotation 3, can be connected by a first clutch 1 to a flywheel 4, which is also supported with freedom to rotate around the axis of rotation 3. In addition, the flywheel 4 can be connected by a second clutch 5 to a transmission shaft 6, also supported with freedom to rotate around the axis of rotation 3. The flywheel 4 is provided with at least one permanent magnet and thus forms the rotor 8 of a crankshaft starter-generator. The pole fields of the permanent magnets can be moved past the stator coil of a stator 9 of the crankshaft starter-generator, this coil being mounted on a stationary component. Each of the first and the second clutches 1, 5 has its own separately operated actuating means and can be engaged and disengaged either independently of each other or in common.
