Abstract

A joined prefabricated individual cam includes multiple cams for an adjustable camshaft in particular for an internal combustion engine of a motor vehicle. The camshaft has two shafts mounted concentrically one inside the other, namely an inner shaft and an outer shaft. The joined multiple cam is fixedly pinned to the inner shaft via radial openings provided in the outer shaft with a rotatable bearing on the outer shaft. Such a multiple cam has at least one prefabricated individual cam which is placed as a cam ring on the outside circumference of a carrier pipe at an axial distance from the neighboring individual cams and is fixedly connected to this carrier pipe at a predetermined angle of rotation and axial distance assignment.
