Abstract: Kingpin assembly for a semitrailer of a road train, including a king pin defining an axis of rotation (A), a pivot bearing arranged around the axis of rotation (A), and a holder connected to the pivot bearing and pivotable around the axis of rotation (A) for indirectly or directly holding an electrical and/or electromagnetic and/or pneumatic and/or hydraulic connecting means wherein the king pin includes a king pin flange for mounting the king pin indirectly or directly to the semitrailer, wherein the pivot bearing includes a fixed bearing ring or a fixed bearing ring segment relative to the king pin and a bearing ring or a bearing ring segment rotatable relative thereto, wherein the holder is fixed to the rotatable bearing ring and wherein a support element, which is axially spaced from the rotatable bearing ring and abuts directly against the king pin, is connected to the holder and is adjustable in length in the radial direction (R) with respect to the axis of rotation (A).
