Abstract: A method for manufacturing a position indicator sensor wheel for a camshaft is disclosed. The position indicator includes an axially extending passage for connecting to the camshaft and at least one radially projecting tooth. The method includes providing a sheet from a sheet material; introducing the passage into the sheet; and roughening a radial inner surface of the passage in at least one rough portion.

Abstract: A method for producing a hybrid component may include placing a metallic insert part into an injection mould, at least one of over-moulding and back-injecting the metallic insert part with a plastic mass, and pretreating a surface of the metallic insert part that is to be at least one of over-moulded and back-injected prior to the at least one of over-moulding and back-injecting. The metallic insert part may be placed into the injection mould such that the metallic insert part protrudes from the plastic mass on at least one side. A material accumulation may be disposed on a transition region from the metallic insert part to the plastic mass.

Abstract: A cylinder head cover of plastic for covering a cylinder head of an internal combustion engine is disclosed. The cylinder head cover includes a bearing track including at least two bearing points each having a bearing opening for supporting a camshaft. A bearing ring is provided in at least one of at least one bearing point and a bearing opening. The bearing ring is injected into the plastic of the cylinder head cover. An oil duct that leads to at least one of the two bearing points and serves for bearing lubrication is arranged in the cylinder head cover.

Abstract: A cylinder head cover for covering a cylinder head of an internal combustion engine having at least one first sealing surface via which the cylinder head cover can be tightly connected to an associated second sealing surface on the cylinder head, the cylinder head cover may include at least one first reference surface configured for unambiguous position-fixing on an associated second reference surface of the cylinder head. The at least one first reference surface and the at least one first sealing surface may be formed separately from one another.

Abstract: A camshaft has at least two completely machined individual cams fixedly mounted on a shaft in predetermined angular positions. The shaft includes an outside shaft and an inside shaft arranged concentrically in the former, and is to be manufactured in such a way that remachining of the joined camshaft is not necessary. This is by combining the individual cams even before they are mounted on a shaft and joining them to this shaft to form a machining module, such that the individual cams are combined in their mutual arrangement in relation to one another in which the cams are to be mounted on the finished camshaft. The final machining of the cams is performed within this machining nodule. When the cams are completely machined in this way, the cams are joined to the shaft of the camshaft within the machining module. This ensures that the desired mutual arrangement is maintained, i.e., that remachining is not necessary.

Abstract: A camshaft for automotive engines in particular having contra-rotating cams capable of rotating over a limited circumferential angle about the camshaft axis in which an inside shaft (2) and an outside shaft (1) are arranged concentrically one inside the other, the contra-rotating cams (3, 4) include first and second cams, of which the first cam (4) is fixedly connected to the inside shaft, and the second cam (3) is fixedly connected to the outside shaft (1), the outside shaft (1) and the inside shaft (2) are mounted with respect to one another, is to be manufacturable economically and with a high manufacturing precision.
