Abstract:
Spring strut domes for use with vehicle bodies can be formed by reshaping a semifinished product into a dome element by way of massive forming. In particular, the semifinished product may be reshaped by rolling, forging, upset-forging, and/or pressing. In this process, structures may be introduced into the dome element that increase the stiffness of the dome element and hence the spring strut dome. Two example structures include ribs and webs, and the dome element may be formed of steel or a steel alloy. In some cases, the semifinished product may be heated before being reshaped into the dome element. Further, the spring strut dome may also include an attaching region coupled to the dome element, which may be used to secure the spring strut dome to a vehicle body. A wall thickness of the attaching region may be equal to or less than 1.5 mm in some examples.
