ABSTRACT:
An adjustable drive connection between an engine crankshaft and engine camshaft is provided by an electric motor connected to the camshaft via planetary gearing to cause relative rotation of an adjusting carrier in relation to a flanged shaft connected firmly to a camshaft. The carrier is fastened to this flanged shaft by means of a thread, so that its relative rotation with respect to the flange shaft is converted into an axial shafting of the carrier along the flange. An actuating element arranged on the carrier is likewise shifted axially. The axial shifting of the actuating element is converted into a relative rotation of the flanged shaft and a chain-wheel carrier driven by a crankshaft via helical teeth on the actuating element.
