Differential side gear and the production method thereof

摘要

The invention relates to a differential side gear comprising internal splines (11) which are used to connect a drive shaft. The inventive differential side gear comprises circular gear teeth (3) and defines a rectilinear blind hole (4) which is used to house and connect an end portion of the drive shaft. Said differential side gear comprises a single forged piece. The aforementioned circular gear teeth (3) and the blind hole (4) are disposed in a coaxial manner and are centred on a rotation axis (X-X') of the differential side gear.
