Abstract
A device for connecting a generator to a belt drive of an internal combustion engine is provided, which includes a belt pulley () that is guided so that it can rotate relative to a hub () set on a shaft (). At least one spring element is arranged between the belt pulley () and the hub () and connects the belt pulley () and the hub () to each other elastically for transferring rotational motion and here sets a relative rotation between the belt pulley () and the hub () corresponding to an effective torsional stiffness. The at least one spring element is placed with a defined movement play (s) with respect to the belt pulley () and/or the hub (), in order to allow relative rotation through the movement play (s) in a first region (I) with a low torsional stiffness, while, in a second region (), a high torsional stiffness can be generated by the at least one spring element.
