In order to provide a coupling unit for a trailer coupling of a motor vehicle comprising a coupling ball and a coupling ball carrier carrying the coupling ball with the aid of which the loads effective thereon when in use can be detected in a reliable and simple manner, it is proposed that the coupling unit comprise a load-bearing structure which engages around a channel extending parallel to an axis, and that a reference finger extending from a first end to a second end in a longitudinal direction approximately parallel to the axis be arranged in the channel, wherein said finger is fixed at the first end such as to be static relative to the load-bearing structure and extends such as to be free from deformations of the load-bearing structure up to the second end, and wherein the second end cooperates with a sensor unit which detects a relative position of the second end relative to a region of the load-bearing structure engaging around it.
