Abstract

The invention relates to a camshaft comprising a support shaft formed as a hollow shaft. An inner shaft is arranged concentrically in the interior of the support shaft, wherein the inner shaft is rotatable relative to the support shaft. There is arranged on the support shaft a first cam segment with a first recess for receiving the support shaft, which cam segment is rotatable with respect to the support shaft and is connected in a rotationally conjoint manner to the inner shaft via a first opening in the support shaft. The first cam segment has at least two cam contours. The connection between the inner shaft and the first cam segment is furthermore configured such that the first cam segment is axially displaceable relative to the inner shaft and to the support shaft.
