    Abstract: A camshaft for the drive of an internal combustion engine has a hollow shaft carrying one or more cams or partial cams and an inner shaft disposed within the hollow shafts and rotatable relative to the hollow shaft. The inner shaft has one or more cams or partial cams disposed outside the hollow shaft and attached for rotation with the inner shaft through clearances in the hollow shaft. A camshaft driving arrangement includes a camshaft timing gear coupled with both shafts and a device responsive to a parameter characteristic of the operating conditions of the drive for adjusting the rotational position of either one or both of the inner and hollow shafts relative to the camshaft timing gear. The adjusting device includes an electric motor fixed on the timing gear and controlled by electrical signals. The motor acts on a threaded spindle which meshes with a counterthread surface on the inner shaft or the outer shaft, or both, for adjusting the relative position of the shaft or shafts relative to top dead center.

    Abstract: An electromechanical camshaft phaser (3) comprises a setting gear (4) and an electric motor (5), which is controlled by means of an electric-motor control unit (6). Data concerning the operation of the electric motor (5) including position changes of its motor shaft are transferred via a data bus (8) from the electric-motor control unit (6) to an engine control unit (7) of the internal combustion engine (1) comprising the camshaft phaser (3). In addition, recurring time signals are transferred from the electric-motor control unit (6) to the engine control unit (7) via a separate line (9), by which harder real-time requirements are met than by the data bus (8). The time signals are used to generate a time difference signal in the engine control unit (7) by comparison with the data received by the engine control unit (7), which time difference signal is fed back to the electric-motor control unit (6) via the data bus (8) and is used there to synchronize the electric-motor control unit (6) with the engine control unit (7).

    Abstract: A housing is rotatable synchronously with a crankshaft of an engine. A plurality of external teeth arrangements is respectively shaped into a ring form and is formed integrally with the housing in one piece and is configured to mesh with a plurality of chains, respectively, each of which is wound around the crankshaft or a sprocket that is rotatable. A cam plate is connected to a camshaft of the engine and is rotatable relative to the housing. A plurality of stoppers is formed integrally with the housing in one piece while the stoppers are configured to limit relative rotation between the housing and the cam plate within a predetermined range when the stoppers contact the cam plate. Each stopper is placed at a position, at which the stopper does not overlap with any of the external teeth arrangements in a view taken in an axial direction of the housing.
