ABSTRACT:
A novel load sensing trailer ball-hitch and drawbar mechanism (30) compatible with industry standard coupling, drawbar receivers and vehicle bumper systems consisting of an upstanding elongated vertical ball-hitch post assembly (4) is provided, featuring the integration of a load sensing device (14) therein. The ball-hitch assembly by means of a threaded stud-bolt (20) received into the threaded lower cavity, is to be attached to industry-standard draw-bar or bumper fittings as used on recreational vehicles, trucks and vans. A drawbar (30), has integrated therein a singular or plurality of load sensing devices (14). Overloading of the force measuring device is achieved by means of a mechanical stop fitting (28). Signals derived from this force measuring device are transmitted to a board computer providing an analog or digital representation of the forces acting upon the ball-hitch drawbar assembly.
