Abstract

See full text

A camshaft drive includes a drive shaft having at least one cam for actuating a valve of an internal combustion engine. A shaft-in-shaft system is disposed parallel to the drive shaft and has an inner shaft and an outer shaft each having at least one cam for actuating a valve. The outer shaft is connected to an outer shaft transmission element in a manner fixed against relative rotation. A hydraulic transmission device includes a stator, a rotor, and an intermediate member. The inner shaft is coupled to the drive shaft via the hydraulic transmission device which is operatively connected to an adjusting device and to a control device for setting a desired phase angle between the inner shaft and the outer shaft. A drive element is coupled to the drive shaft. The drive element is directly coupled both to the outer shaft transmission element and to the stator.
