Abstract
A process for producing a twist-beam axle is provided. Related thereto, the twist-beam axle has a light metal longitudinal link and an iron metal transverse arm. The process contains the following steps: producing a casting mold for the respective longitudinal link; inserting one end of the transverse arm into a corresponding recess in the casting mold; then pouring the liquid light metal into the casting mold for the longitudinal link; cooling the poured light metal; and removing the transverse arm joined to the cooled light metal from the casting mold.
Claims8
A process for producing a twist-beam axle, which
- respectively has a light metal longitudinal link and an iron metal transverse arm, said process comprising at least the following steps:
- producing a casting mold for the respective longitudinal link,
- inserting an appropriate end of the transverse arm into a corresponding recess in the casting mold, wherein the cross-section of the end of the transverse arm is formed to have a U-shape, a V-shape, a round shape, an elliptical shape, or a polygonal shape, the cross-section of the end being different from the cross-section of a central portion of the transverse arm,
- then pouring liquid light metal into the casting mold for the longitudinal link,
- cooling the liquid light metal introduced into the casting mold, and
- removing the cooled light metal joined to the end of the transverse arm from the casting mold.
