  • Patent number: 9249692
    Abstract: The invention relates to a camshaft for an internal combustion engine with a shaft and at least one cam joined therewith, which is connected via a joining surface on the cam side with a joining surface on the shaft side. The joining surface on the cam side and alternatively or additionally the joining surface on the shaft side may be constructed such that they have a predefined roughness. Hereby, the friction between the shaft and the cam can be increased. The invention further relates to a cam for such a camshaft and a method for the manufacture of such a camshaft or respectively of such a cam.

  • Patent number: 9222374
    Abstract: A camshaft for a combustion engine has a shaft and at least one cam thermally joined to a joining surface on the shaft side via a joining surface on the cam side. The shaft is embodied as a drawn and not additionally worked tube. Because of this the production of commercial vehicle camshafts can be realized in a more cost-effective manner since these do not have to be additionally ground or turned.
