# Kingpin for a fifth-wheel coupling, fifth-wheel coupling with kingpin, and utility vehicle therewith

## Abstract

The invention relates to a kingpin ( 10 ) for a fifth-wheel coupling of a utility vehicle, with a journal shaft ( 3 ) which extends along a centre axis (M) and has a journal head ( 2 ) at its lower end, wherein the journal shaft ( 3 ) has a fastening flange ( 4 ) at its upper end remote from the journal head ( 2 ), and with a receiving flange ( 5 ) which is placed onto the upper end of the journal shaft ( 3 ) and is fixed to the fastening flange ( 4 ). According to the invention, a measuring device for detecting driving-dynamic reaction forces is provided, wherein the measuring device is arranged in a cavity ( 15 ) which is formed in the fixed state between the receiving flange ( 5 ) and the upper end of the journal shaft ( 3 ).
