Abstract
A process for allowing pretreatment of components for an assembled camshaft in the course of whose production drive elements are attached in a force-locking way to a tube through plastic expension of individual tube portions while exceeding the limit of elasticity of the material, in the case of which, while using a tube material with a low yield point suitable for plastic expansion relative to the drive elements, the material at one tube end for the purpose of inserting a sleeve which is connected to a driving pinion and which is to be expanded, is quenched and tempered to achieve an increased tensile strength, or the tubular portions intended to be used as bearing regions are surface hardened in order to achieve bearing properties.
