Intermediate shaft

The intermediate shaft serves to compensate for the offset of the differential in front-wheel drives, so that constant-velocity shafts of the same length can be used on both sides. This intermediate shaft is a three-part type comprising two stubs and a tube which are joined by friction welding. The part is then soft machined by means of turning and rolling the splines before being induction hardened, hard machined without twist and provided with a coating inline (in the production line cycle time).
