Abstract
A device () for changing the timing of an internal-combustion engine () is provided that has a camshaft adjuster (), which is supported on a non-rotating bearing journal (). A driving wheel () of the camshaft adjuster () is driven by a crank-shaft () via a first traction mechanism drive (). The rotation of the driving wheel () is transferred via an actuator () to a driven part (), which is arranged so that it can rotate relative to the driving wheel (). Second and third traction mechanism drives () create a drive connection between the driven part () and two camshafts ().
