Abstract
A device (1) for changing the timing of an internal-combustion engine (2) is provided that has a camshaft adjuster (5), which is supported on a non-rotating bearing journal (6). A driving wheel (8) of the camshaft adjuster (5) is driven by a crank-shaft (3) via a first traction mechanism drive (7). The rotation of the driving wheel (8) is transferred via an actuator (10) to a driven part (9), which is arranged so that it can rotate relative to the driving wheel (8). Second and third traction mechanism drives (11, 12) create a drive connection between the driven part (9) and two camshafts (4, 4a).
