Abstract

A cylinder head of an internal combustion engine includes a camshaft configured to actuate gas-exchange valves of the internal combustion engine. The camshaft has two cam segments that are joined to each other in such a manner that the cam segments cannot rotate with respect to each other, but are moveable axially relative to each other. End faces of the bearing sites of the cam segments each have splines running radially along respective outer circumferential surfaces of the cam segments. A camshaft bearing has an inner bearing ring with splines being formed on an inner surface. The splines of the inner bearing ring completely penetrate the axial course of the inner surface and the splines of the adjacent cam segments intermesh with the splines of the inner bearing ring on both sides thereof such that the inner bearing ring forms a non-rotating connection between the camshaft segments.
