Abstract
The present invention relates to a camshaft () having cams (and) rotatable with respect to one another about the camshaft axis () over limited circumferential angles, whereby an inside shaft () and an outside shaft () are arranged coaxially one inside the other. The cams (and) that are rotatable with respect to one another each consist of first cams () and second cams (), whereby the first cams () are fixedly connected to the inside shaft () and the second cams () are fixedly connected to the outside shaft (), each by means of a fixation device (). It is essential to this invention that the first cams () each have a first through-bore () which is aligned with a respective second through-bore () in the inside shaft () when the first cam () is installed. In addition, the fixation device () is formed by two essentially identical fixation pins (and') with respect to their axial longitudinal extent. The present invention also relates to a method for manufacturing such a camshaft ().
