Abstract: A method for arranging a camshaft in a camshaft module includes arranging cam elements and a switching element on a carrier tube to so as to form a displacement element having a bearing section, outside or external to a module housing. The carrier tube is then cut in a region of a bearing section to form two parts. One of the parts is arranged into a bearing bridge in a module housing. The other part is then joined to the first part that was inserted into the bearing bridge.

Abstract: A hollow-cylindrical camshaft may include a closing cover and supply openings. Slipping of the closing cover may be prevented by indentations introduced into the camshaft. The indentations may be inwardly rolled portions, impressions, notches, or plastic deformations, for instance, introduced from the outside by punches or holding means that project into the interior of the camshaft. The indentations may be arranged in one or more planes orthogonal to an axial direction of the camshaft, wherein the indentations are rotationally symmetrical or can be arranged symmetrically or asymmetrically. The indentations can be mounted in the axial direction either between the closing cover and the supply opening located closest to the closing cover, or at the same axial positioning as the supply opening such that slipping of the closing cover over the supply opening is prevented.

Abstract: A pre-assembled camshaft module for attachment to a cylinder head of an internal combustion engine includes a cylinder head cover, at least one camshaft, and bearing elements to which the camshaft is rotatably mounted. The bearing elements are formed as bearing brackets, which are connected by attachment members to the cylinder head cover at individual attachment points, in order to produce the pre-assembled camshaft module. The camshaft module is connectable to the cylinder head at the attachment points by the attachment members.
