Abstract

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.
