Abstract
A multipoint link for an undercarriage of a vehicle, having a core element formed from a foamed material and at least one roving of bundled continuous filaments wound around the core element, the at least one roving winding around the core element in at least one layer forming an outer layer of the multipoint link. The recesses serving to guide the at least one roving to be laid by winding are incorporated in the surface of the core element.
Claims14
A multipoint link for an undercarriage of a vehicle, comprising:
- a core element formed from a foamed material;
- at least one roving of bundled continuous filaments wound around the core element,
- wherein the at least one roving winding around the core element in at least one layer forms an outer layer of the multipoint link;
- and
- recesses configured to guide the at least one roving to be laid by winding are incorporated in a surface of the core element, wherein walls that laterally delimit the recesses have undercuts,
- wherein the recesses are arranged independent from free geodesic paths on the surface of the core element.
A multipoint link for an undercarriage of a vehicle, comprising:
- a core element formed from a foamed material;
- at least one roving of bundled continuous filaments wound around the core element,
- wherein the at least one roving winding around the core element in at least one layer forms an outer layer of the multipoint link;
- and
- recesses configured to guide the at least one roving to be laid by winding are incorporated in a surface of the core element, wherein walls that laterally delimit the recesses have undercuts,
- wherein the recesses have at least one of an arcuate cross section and a polygonal cross section,
- wherein a combination of different cross-sectional shapes within an extension of a respective recess are provided in one or more transition points or highly curved transition zones in that the recess has a polygonal cross section in the latter, while the recess has a substantially arcuate cross section before and after the one or more transition points or highly curved transition zones.
A method for producing a multipoint link, comprising:
- producing a core element from a foamed material;
- incorporating recesses in a surface of the core element, wherein the recesses are incorporated during or after production of the core element, wherein walls laterally delimit the recesses have undercuts;
- and
- winding, around the core element, at least one roving of bundled continuous filaments which is laid in the recesses,
- wherein the recesses are arranged to intersect on the surface of the core element, and
- wherein the intersecting recesses have different depths.
