Abstract: A king pin arrangement includes a king pin and a mounting member, the mounting member comprising a receiving plate, the king pin having a base section and a king pin head, the king pin extending in a king pin direction, wherein a positive king pin direction points from the base section to the king pin head, wherein the king pin is fastened directly and/or indirectly to the mounting element by the base section in a form-fitting, force-fitting and/or material-fitting manner, the king pin being fastened such that the king pin is rotationally fixed to the mounting element in a circumferential direction about the king pin direction, wherein the mounting element and/or the king pin has a first measuring surface which has a continuous height profile along an extension of the remaining surface in the direction of the king pin direction.

Abstract: A fifth-wheel coupling arrangement includes a primary coupling apparatus and a fifth-wheel plate that includes a semitrailer surface having an outward-pointing normal, and an insertion opening that extends in an insertion direction, the primary coupling apparatus includes a main body, a drive mechanically connected to a cover apparatus via a coupling mechanism, and a plug element having energy conducting contacts that point in a plug-in direction, wherein the cover apparatus includes a cover element displaceable by the drive between a first position where the plug element is exposed, and a second position where the plug element is covered, and wherein the insertion direction is substantially parallel to the plug-in direction.

Abstract: A fifth wheel coupling includes a fifth wheel coupling plate having a bearing surface having a normal and an retraction opening for a king pin and configured to prevent the king pin from being moved out of the retraction opening when in a closed position, and allow the king pin to be moved out of the retraction opening when in an open position, an actuating device having an actuating area extending along a longitudinal axis and configured to transfer the locking mechanism from the closed position to the open position, and a transmission area configured to transfer forces to the locking mechanism, and a safety device including a locking arrangement pivotably mounted about a pivot axis such that the locking arrangement can be moved into a locking position and into a release.

Abstract: An adapter arrangement, in particular fifth wheel adapter arrangement, for a semitrailer train, comprising a base body, a coupling arrangement, in particular a fifth wheel coupling plate, and a king pin, wherein the king pin is fixed indirectly and/or directly to the base body, wherein in particular the coupling arrangement is stationary relative to the king pin.
