Process for producing a twist-beam axle in a hybrid construction

The invention relates to a process for producing a twist-beam axle, which respectively has a light metal longitudinal link and an iron metal transverse arm. The invention proposes a process comprising at least the following steps: a casting mold is produced for the respective longitudinal link, an appropriate end of the transverse arm is inserted into a corresponding recess in the casting mold, only then is liquid light metal poured into the casting mold for the longitudinal link, the light metal melt introduced into the casing mold is allowed to cool, the cooled light metal joined to the end of the transverse arm is removed from the casting mold.
