Abstract

A trailer coupling including an intermediate unit to be inserted between a standard-type connecting coupling and a trailing vehicle and having integrated therein a force measuring cell for determining vertical forces. Furthermore, horizontal pushing and pulling forces may be determined by integrating at least one force measuring cell acting in horizontal direction. The fifth wheel coupling of semi-trailers may have integrated force measuring cells measuring forces acting in vertical, longitudinal, horizontal and/or lateral horizontal directions.
