1. A multipoint link (1) for an undercarriage of a vehicle, comprising:
a core element (5) formed from a foamed material and at least one roving (10) of bundled continuous filaments wound around the core element (5),
1 wherein the at least one roving (10) winds around the core element (5) in at least one layer and forms an outer layer of the multipoint link (5),
1 wherein the core element (5) is constructed as a hollow body that comprises at least two shell elements (11, 12),
1 wherein the at least two shell elements (11, 12), which are mated together to form the core element (5), are formed with walls (13, 14) substantially parallel to one another and which delimit an outer contour,
1 wherein the walls (13, 14) have complementary undercuts (29) formed as projections in the form of steps at abutment surfaces facing one another such that the at least two shell elements (11, 12) are positively engageable in one another in portions, wherein each projection is substantially parallel to at least one wall,
1 wherein each of the walls (13, 14) have an inner side and an outer side that are completely parallel to each other and the undercuts (29) connect the inner side to the outer side, and
1 wherein the at least two shell elements (11, 12) are connected to one another by material bonding by gluing the abutment surfaces such that the hollow body forming the core element is constructed fluid-tight.
