Camshaft and associated cam

摘要

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.
