Abstract

An assembled camshaft includes an outer hollow camshaft body and an inner camshaft body disposed within the outer hollow camshaft body and mounted so as to rotate relative to it by a predetermined angle. The camshaft also includes at least two separate cam elements. A first cam element is connected with the inner camshaft body so as to rotate with it, and is disposed so as to rotate relative to the outer hollow camshaft body. A second cam element has at least two partial cam elements, in such a manner that a first partial cam element is disposed on the outer hollow camshaft body, so as to rotate with it, and a second partial cam element is connected with the inner camshaft body, so as to rotate with it, and is disposed so that it can be rotated relative to the outer hollow camshaft body.
