Abstract
A camshaft that is assembled or is to be assembled carries at least one cam element that is to be disposed on a main camshaft body to be rotationally fixed and axially movable, and at least one cam element to be disposed on the main camshaft body so as to be rotationally fixed and axially immovable. The main camshaft body has first axial sub-sections having a multi-tooth profile, so that due to a positive connection between shaft and hub the cam element to be disposed in the sub-section so as to be axially movable is seated so as to be rotationally fixed. The main camshaft body also has second axial sub-sections having an extended diameter so that by a non-positive connection between shaft and hub it is ensured that the cam element to be disposed in the sub-section is seated so as to be rotationally fixed and secured against movement.
