Description

FIELD

This invention relates to assemblies for mounting trailer hitches to vehicles.

BACKGROUND

Trailer hitch mounting assemblies according to the prior art are typically weldments. Welded joints display certain disadvantages. For example, they require skilled welders or sophisticated robotic welding machines, both of which add to the cost of production. Weld quality must be ensured by inspection techniques which also require sophisticated equipment and skilled inspectors. Weldments are furthermore made specific to a particular design, and thus lack versatility in their design and employment. There is clearly an opportunity to improve trailer hitch mounting assemblies and avoid the disadvantages of weldments.

Trailer Hitch Mounting Assemblies

FIG. 1 shows an example embodiment of an assembly 10 for mounting a trailer hitch 12 to a vehicle (not shown). Assembly 10 comprises a cross beam 14 having first and second ends 16 and 18 oppositely disposed from one another, wherein the cross beam extends continuously between the first end and the second end. In some optional aspects, the cross beam 14 can be a straight cross beam between the first end and the second end, without bends. Cross beam 14 is advantageously a hollow tube 20 which defines a bore 22 (see FIG. 2). In this example tube 20 has a rectangular cross section 24. In a practical design, tube 20 may be formed from seamless or seamed steel tubing for strength, robustness and low cost.

First and second attachment fittings 26 and 28 are mounted respectively on the first and second ends 16 and 18 of the cross beam 14. Attachment fittings 26 and 28 are adapted to attach the cross beam 14 to the vehicle. As shown in FIG. 3, each attachment fitting 26 and 28 (26 shown) comprises a plug 30 from which a flange 32 extends perpendicularly outwardly. Plug 30 is sized and shaped to fit within the bore 22 of tube 20 (FIGS. 1 and 2), and thus has a rectangular perimeter 34. It is advantageous to match the size and shape of the plug 30 to the bore 22, and different plug shapes will be used for different tubes 20. As shown in FIGS. 1 and 2, attachment fittings 26 and 28 are attached to the cross beam 14 using a plurality of fasteners 36 which extend though pre-drilled holes 38 in the cross beam 14 and the plugs 30 (see also FIG. 3). Each flange 32 defines a plurality of apertures 40 which receive additional fasteners (not shown) to attach the cross beam to the vehicle. Attachment fittings 26 and 28 are advantageously formed of cast metal such as iron or steel, but they may also be machined from a billet or metal injection molded.

As shown in FIG. 1, a hitch receiver 42 is mounted on the cross beam 14 between the first and second ends 16 and 18. Hitch receiver 42 may also be cast from metal such as iron or steel, metal injection molded or machined from a billet. Hitch receiver 42 comprises a receptacle 44 (see also FIG. 4) adapted to receive the bar 46 of the trailer hitch 12, the bar 46 being retained within receptacle 44 by a lock pin 48 secured by a cotter pin 50 as is known in the art. As shown in FIG. 4, hitch receiver 42 also comprises a girth 52. Girth 52 has first and second ends 54 and 56 attached to the receptacle 44 so that the girth surrounds the cross beam 14 when the hitch receiver 42 is mounted thereon. Hitch receiver 42 also comprises a chain plate 58 (see FIGS. 1 and 2). Chain plate 58 defines first and second holes 60 positioned on opposite sides of the hitch receiver 42. The holes 60 receive safety chains (not shown) typically used to ensure that the trailer does not depart from the vehicle in the event of a hitch failure or malfunction. Hitch receiver 42 may be attached to the cross beam 14 using a plurality of fasteners 62.

Also disclosed herein is a kit 64 for constructing an assembly 10 for mounting a trailer hitch 12 to a vehicle, an example being shown in FIG. 2. In a practical example, kit 64 comprises cross beam 14, attachment fittings 26 and 28, hitch receiver 42 and various fasteners 36 and 62 for fixing the attachment fittings and hitch receiver to the cross beam. Kit 64 may also include the trailer hitch 12 and its lock pin 48 and cotter pin 50 shown in FIG. 1. An advantage of the kit 64 is that different components can be selected to comprise the kit to permit an assembly to fit different requirements. For example, different length cross beams 14 may be used, or different attachment fittings as well as a different hitch receivers, thereby providing great versatility. It is further advantageous to affix the components to the cross beam using fasteners, such as bolts and nuts as opposed to welding. Ensuring consistent and high quality welds in mass production is an expensive task requiring sophisticated test equipment as well as experienced personnel to perform the inspection. The welding process itself requires skilled welders and expensive welding apparatus. In comparison a bolted assembly is easier and less expensive to construct and inspect because it requires less sophisticated equipment and less skilled personnel.

Also disclosed is a method of making an assembly 10 for mounting a trailer hitch 12 on a vehicle. In one example embodiment, illustrated in FIGS. 1 and 2, the method comprises:

mounting a hitch receiver 42 onto a cross beam 14;

mounting a first attachment fitting 26 to a first end 16 of the cross beam; and

mounting a second attachment fitting 28 to a second end 18 of the cross beam.

The method may further include attaching the trailer hitch 12 to the hitch receiver 42.

The step of mounting the hitch receiver 42 to the cross beam 14 may comprise sliding the cross beam 14 through a girth 52 having first and second ends 54 and 56 attached to a receptacle 44 comprising the hitch receiver 42. The first end 16 of the cross beam 14 can be inserted through the girth 52 until the girth is positioned between the first end 16 and the second end 18 of the cross beam. Accordingly, the girth 52 can be configured to receive the first end 16 of cross beam 14 and slide along the cross beam until the girth is positioned between the first end and the second end 18 of the cross beam. In the example method a plurality of fasteners 62 may be used to affix the hitch receiver 42 to the cross beam 14. The step of mounting the first attachment fitting 26 to the first end 16 of the cross beam 14 may comprise inserting a first plug 30 comprising the first attachment fitting 26 into a bore 22 defined by the cross beam 14. A plurality of fasteners 36 may be used to affix the first attachment fitting 26 to the first end 16 of the cross beam 14. A second attachment fitting 28 may be attached to the second end 18 of the cross beam 14 by inserting a second plug 30 comprising the second attachment fitting 28 into the bore 22 defined by the cross beam. A plurality of fasteners 36 may be used to affix the second attachment fitting 28 to the second end 18 of the cross beam 14.

Assemblies 10 for mounting trailer hitches 12 to vehicles are expected to provide various advantages over welded structures. The advantages include greater versatility in application, more economic fabrication and inspection, and elimination of stress and fatigue failure modes associated exclusively with weldments.
