A camshaft adjuster for an internal combustion engine is composed of an adjusting gear designed as a triple-shaft gear, with a drive wheel which is driven from the internal combustion engine and via which the drive torque for the camshaft is introduced, of a gear output coupled fixedly in terms of rotation to the camshaft, and of a gear input wheel which is coupled to a drive motor and via which the adjusting torque causing the relative rotation between the drive wheel and gear output is introduced into the adjusting gear. The cam adjuster includes a failsafe mechanism which causes blocking of the adjusting gear and which, in the event of the absence of an adjusting torque to be introduced via the gear input wheel, acts upon a gear element located between the drive wheel and gear output.

Camshaft adjuster

A camshaft adjusting means for an internal combustion engine includes an adjusting mechanism which is configured as a three-shaft gear mechanism having a drive side into which the drive moment for the camshaft is introduced, an output side which is connected fixedly to the camshaft so as to rotate with it, and an adjusting shaft which is coupled to a drive motor and via which a moment which brings about the relative rotation of the drive side with respect to the output side is introduced into the adjusting mechanism. The adjusting mechanism having one bearing point on each of its drive side and its output side and being mounted via the bearing points with respect to the component which supports the camshaft, in particular the cylinder head of the internal combustion engine. The adjusting shaft is guided into the adjusting mechanism through one of the bearing points.

Camshaft adjusting means

A clutch shaft for a camshaft controller having at each of two ends () thereof a rotating joint which equalizes the angle between the axes. An actuator for controlling a camshaft adjustment transmission includes a clutch shaft for controlling the camshaft adjustment transmission to the actuator via a first rotating joint which equalizes the angle between the axes which is coupled in a region of the actuator which faces away from the adjustment transmission.
