摘要
Standard camshafts, produced by an internal high-pressure forming method (IHU) and whereof the cam rings (1) are fixed on a hollow shaft by force-closure and form-closure, said rings being produced in accordance with their function in a separate process, have the drawback that the cam rings are deformed, mainly in the tip zone (2) of the cams, can result in cracking or breaking. The invention is characterized in that the cam ring is produced in terms of its material properties such that in its outer zone (3) the material is hard and resilient over a specific length while exhibiting nevertheless low plastic deformation, the zone located beneath being relatively flexible and plastically deformable. The inventive camshafts are used almost exclusively in motor vehicles engines.
