TRAILER COUPLING AND LOAD SUPPORT DEVICE FOR A TRAILER COUPLING

In order to improve a trailer coupling for motor vehicles, comprising a ball neck which can be mounted to the rear section of a motor vehicle by means of a ball neck carrier at a first end and which carries a coupling ball at a second end, such that load carriers can be mounted and held securely in a simple manner, it is proposed that at least one first positioning body for positioning a load carrier holding device that can be placed onto the coupling ball and the ball neck is arranged on the ball neck at a defined distance from the coupling ball, that the at least one first positioning body is arranged on a ball neck section of the ball neck, which section adjoins a ball extension of the ball neck carrying the coupling ball and in particular extends starting from the ball extension along the ball neck over a distance that corresponds at most to one and a half times the diameter of the coupling ball, and that the at least one first positioning body extends transversely to a course of the ball neck section carrying this positioning body and away from it.
