- the coupling device is designed such that in that release state substantially no torque between the generator rotor disk and a driven component of the generator is transmitted, so that when operating the internal combustion engine in that release state substantially no mechanical Work is withdrawn by the generator from the traction drive and the inertia-prone components of the generator have no effect on the loads in the traction drive.
- the coupling device is preferably designed according to a particular aspect of the invention as a dog clutch.

- the concept according to the invention advantageously achieves a significant reduction in the effective total engine mass moment of inertia. This results in particular for the engine start a significant reduction in the effective FEAD or total engine inertia. In addition, a decoupling at critical speeds is possible.
- the inventive concept advantageously allows a lower belt pretension. This results in an advantageous manner a reduction of the (friction) power loss. In addition, compared to previous concepts significantly lower forces on all components in the belt drive.
- the inventive concept also makes it possible to reduce the reactive power surge in the region of the generator.
- the concept according to the invention comprises the approach of incorporating into a generator disk a coupling, in particular a dog clutch and optionally an additional gear.

- an appropriate control or regulation which is possibly also connected to the engine-ECU, then the following can be achieved: 1.
- the generator can be switched off during critical operating conditions (in both directions!) ZBog claw clutch of the engine speed x translation (eg at speed 0 and thus the image performance is also 0); 2.
