The present invention relates to vehicle frame assemblies. Specifically, the present invention relates to vehicle frame assemblies, such as truck or trailer frame assemblies, and methods for preparing vehicle frame assemblies without the need for welding, including methods and assemblies in which the components may be galvanized prior to or after assembling the components to make the vehicle frame assembly for corrosion prevention and wherein components of the vehicle frame assemblies are connected via brackets designed to bridge and connect the assembly components through such brackets and associated fasteners.
Vehicle frame assemblies serve as support structures on which a vehicle or trailer can be positioned. Many conventional vehicle frame assemblies are formed using a number of longitudinal beams or rails and crossbeams or crossmembers. The longitudinal beams and crossbeams of such vehicle frame assemblies are often formed from metal and are generally joined to one another by welding. The resulting welded vehicle frame assembly is sometimes coated or galvanized to inhibit corrosion of the vehicle frame assembly. The galvanized coating can be applied by spraying, but is commonly applied by dipping the entire frame assembly in a tank filled with a galvanizing fluid, such as molten zinc. Thus, the welded vehicle frame assembly is typically galvanized all at once. However, such conventional methods for preparing vehicle frame assemblies have a number of drawbacks.
Welding the components of a vehicle frame assembly requires highly skilled welders to prepare the vehicle frame assemblies, increasing the cost of assembling the vehicle frame assembly. Further, welding restricts the materials that can be used to construct the vehicle frame assembly as not all metals can be practically welded to one another for strength applications. For example, welding generally would not be used to successfully prepare a vehicle frame assembly having aluminum crossbeams and a stainless steel, longitudinal beam. Additionally, frame assemblies formed by welding cannot be disassembled once the longitudinal beams and crossbeams are welded together. As a result, the vehicle frame assembly cannot be transported in pieces and assembled at a desired location. Instead, it is generally transported as a completed vehicle frame assembly. Transporting the completed frame assembly requires a considerable amount of space and can be cumbersome, inconvenient expensive and poses a risk of damage to the completed frame assembly. Further, as the whole vehicle frame assembly is galvanized at once, large tanks are required into which the entire vehicle frame assembly can be dipped, which also requires significant space, slowing down the overall process efficiency. Galvanizing is generally not performed prior to welding of the components of the vehicle frame assembly, as the welding process can damage or deteriorate the galvanized coating.
To overcome these drawbacks, some methods of preparing vehicle frame assemblies are known in which the beams of the vehicle frame assembly are galvanized prior to assembling the vehicle frame assembly. One such reference is International Patent Application Publication No. WO 03/053770 which describes a method for assembling a platform underframe for motor vehicles including bolted, punched, bent-plate elements and specific parts having precise perforations. To avoid welding of the parts, the parts of the assembly can be galvanized prior to assembly.
U.S. Patent Application Publication No. 2007/0194564 discloses a method of assembling a trailer including a frame having fabricated beams with a web section and a pair of opposing flanges. The flanges may include web-receiving slots. The flanges may also include obtuse ends which may include recesses for receiving fasteners used to secure crossmembers. Securement is achieved using fasteners, such as self-piercing rivets. The web and flanges may be pre-coated to provide a finished beam upon assembly so that welding is not required.
While these references disclose coating or galvanization of vehicle frame assembly parts prior to assembling the vehicle frame assembly, such prior art non-welded frame connections are not yet believed to provide a secure and strong connection between the longitudinal beams and crossbeams so as to enable the vehicle frame assembly that is able to reliably support heavy loads and maintain its integrity when subjected to shear and torsional stresses. Directly connecting such the beams with fasteners is generally believed to yield a connection that is not sufficiently strong. Further, it can be difficult to properly align the longitudinal beams and crossbeams for placing connecting fasteners.
While various brackets are generally known, brackets that are specifically designed for connection of beams and crossbeams of a vehicle frame assembly while facilitating proper alignment of the bracket on the beam or crossbeam and maintaining the strength and integrity of the assembly are not believed to be known in the art.\
Therefore, there is a need in the art for a vehicle frame assembly where the components can be galvanized before assembling the components to form the vehicle frame assembly and where the components can be secured without the use of welding while ensuring a strong and stable connection between the longitudinal beams and crossbeams and maintaining proper alignment as well as providing a way to easily disassemble the frame for transportation and to reassemble it at a lower cost. Further, there is a need in the art for a vehicle frame assembly that facilitates proper positioning of the longitudinal beams and crossbeams and that facilitates connection of the beams using appropriate fasteners which may also be galvanized.

The present application relates to galvanized vehicle frame assemblies. The vehicle frame assemblies may be, for example, truck or trailer frame assemblies that are configured to support a portion of a vehicle or a trailer. The vehicle frame assemblies include components joined by brackets and fasteners so that welding is not required. As a result, the vehicle frame assemblies of the present invention can be assembled by general laborers, rather than by highly skilled welders. Further, the present invention has the advantage that the mechanical fasteners used to connect the vehicle frame assembly components have a known engineering strength, whereas the mechanical strength of a weld is not readily known and may vary from one welded connection to another. The present invention allows for galvanization of the components of the vehicle frame assembly prior to assembly of the vehicle frame assembly, which allows galvanization to be accomplished more easily and with less expense. Further, the galvanized vehicle frame components can be transported separately and assembled at a desired location where they may be galvanized more efficiently than most prior art systems generally known.
Galvanization can be accomplished by any means known in the art, and the present invention is not limited by the specific method by which the vehicle frame assembly components are galvanized. While the present application refers generally to “galvanization” or “galvanized coatings,” it is understood that the components of the vehicle frame assembly of the present invention can receive additional or alternate surface treatments prior to assembly of the vehicle frame assembly, such as primers, paints, or other coatings to inhibit corrosion and/or wear, or which provide improved surface properties or a desired aesthetic appearance.
The brackets of the present invention provide the vehicle frame assembly with additional strength and stability relative to other methods of joining vehicle frame assembly components. The brackets facilitate connection of the rails and crossmembers and facilitate proper positioning of the preferably pre-galvanized vehicle frame assembly components. Further, the use of brackets allows for connection of vehicle frame assembly components composed of different materials, such as aluminum and steel, which cannot generally be joined via welding.
The present application in some embodiments will be described using words such as “upper” and “lower,” “inner” and “outer,” “right” and “left,” “interior” and “exterior,” and the like. These words and words of similar directional import are used for assisting in the understanding of the invention when referring to the drawings or another component of the invention and, absent a specific definition or meaning otherwise given by the specification, such terms should not be considered limiting to the scope of the invention.

The rails 110 are arranged generally longitudinally, and the crossmembers 120 are arranged generally transversely to the rails 110. Preferably, the crossmembers 120 are positioned substantially perpendicularly to the rails 110. When two or more rails 110 are present (as shown) the rails 110 are arranged substantially parallel to one another and are spaced apart. It should be understood based on the disclosure that just one, two, or three or more rails 110 may be used depending on the size or requirements for use of the assembly 100. Similarly, the crossmembers 120 are preferably arranged so that they are substantially parallel to one another and are also spaced apart.
The rails 110 are preferably arranged in a first plane and the crossmembers 120 are arranged in a second plane that is substantially parallel to the first plane. In a preferred embodiment, the second plane in which the crossmembers 120 are arranged is elevated above the first plane so that the crossmembers 120 are stacked on the rails 110. However, in an alternate embodiment, the second plane may be positioned beneath the first plane so that the rails 110 are positioned on top of the crossmembers 120. The number of crossmembers may also be varied as would be understood by one skilled in the art based on this disclosure, so as to allow for different load support and/or depending on the length and requirements of the frame design.

The first plate 132 is arranged in a first plane, P1, that is perpendicular to a second plane, P2, in which the second plate 134 is arranged, and the first plate 132 and the second plate 134 are preferably always spaced somewhat apart. The connection section 136 extends between and connects an interior end 131 of the first plate 132 and an interior end 133 of the second plate 134. In the illustrated embodiment, the bracket 130 has a width, w3, measured transversely across the bracket along a direction that is transverse to the longitudinal axis Z of the bracket 130.
The bracket 130 is preferably formed from metal, such as aluminum or steel, and may alternately be composed of a composite material. The bracket 130 may be galvanized and/or coated to inhibit corrosion and wear, to improve surface properties, and to provide a desired aesthetic appearance. The bracket 130 may be of unitary construction, and may be formed by bending a blank formed from a sheet or plate into the desired configuration. However, the present invention is not limited by the specific method of forming the bracket and the brackets may be alternatively be formed via molding.
The connection section 136 bridges an area, A, defined between the first plate 132 and the second plate 134 of the bracket 130. The connection section 136 includes a first portion 139 adjacent to the first plate 132 and a second portion 137 adjacent to the second plate 134. The second portion 137 is substantially parallel to the first plate 132 but is arranged in a plane separate from, and in the embodiment shown above, the plane P1 of the first plate 132.

As shown in
In an alternate embodiment (not shown) rather than being inclined or sloped, the first portion 139 may be substantially perpendicular to the second portion 137 of the connection section 136. A perpendicular first portion 139 may allow the bracket 130 to fit more closely to a flange of a rail or crossmember to which the bracket is connected depending on the design and thickness of the rail or crossmember. As shown, the first portion 139 of the connection section 136 forms an angle a1 with a plane P1 of the first plate 132 of about 10 degrees to about 90 degrees. The angle a1 may be varied depending upon the configuration of the rail 110 and crossmembers 120.

When the bracket 330 is installed on an upper side (not shown) of a vehicle frame assembly 300, the second plate 334 is configured so as to be connectable to a flange of a crossmember and the connection section 336 would then slope downwardly from the second plate 334 to the first plate 332 which would be connected to an upper flange of a rail 310. Thus, the connection section 336 would span the difference in elevation of the first plate 332 positioned on a flange of a rail and the second plate 334 on a flange of a crossmember. Further, the connection section 336 would bridge the area, A, between the first plate 332 and second plate 334. In this way, the bracket 330 is configured so that it generally contours to the shape of the flange of the rail and the flange of the crossmember and the bracket 330 and helps to facilitate proper alignment of the rail 310 and crossmember 320.
As shown in
As shown in the blank for the bracket in
The bracket 330 is preferably formed from metal, such as aluminum or steel, or may be formed from a composite material. The bracket 330 may be galvanized and/or coated to inhibit corrosion and wear, to improve surface properties, and to provide a desired aesthetic appearance. The bracket 330 may be of unitary construction, and may be formed by bending a blank formed from a sheet or plate into the desired configuration. However, the present invention is not limited by the specific method of forming the bracket, and the bracket may alternatively be formed via molding.
The first plate 332 and second plate 334 of the bracket 330 may each define apertures 338 which extend through the bracket 330 from a first surface 341 to an opposing surface 342 of the bracket 330. In the illustrated embodiment, the first plate 332 has a pair of apertures 338 that are aligned in a direction transverse to the longitudinal axis Z of the bracket 330. Similarly, the second plate 334 has a pair of apertures 338 that are aligned in a direction transverse to the longitudinal axis Z of the bracket 330. The apertures 338 of the second plate 334 are preferably positioned at opposing ends of the second plate 334 in a transverse direction as shown in
The vehicle frame assembly 300 may include brackets 330 on an upper side and/or lower side thereof, as shown in
The width of the first plate 332 of the bracket 330 is preferably the same as or less than the width of the flange 312 of the crossbeam 320 as shown in
The connection section 336 slopes from the second plate 334 towards the first plate 332 so as to span the difference in elevation. In this way, the bracket 330 fits closely to and contours to the shape of the rail 310 and crossmember 320 and helps to properly position the rail 310 and crossmember 320 and provides support and stability. The bracket 330 is shown as being positioned on an outer side 303 of the rail 310, however, the brackets 330 can alternately or additional be positioned on an, opposing interior side 304 of the rail 310.
The first and second plates 332, 334 of the brackets 330 can be secured to the surfaces of the rail 310 and crossmember 320 in the same manner as discussed above with respect to assemblies 100, 200. Thus, the first and second plates 332, 334 of the brackets 330 may be secured to respective rails 310 and crossmembers by fasteners as discussed herein. In embodiments of the bracket 330 having apertures, the apertures of the first plate 332 are aligned with apertures of the flange of the rail 310 so that a fastener can be inserted through the aligned apertures. Similarly, the apertures of the second plate 332 are aligned with apertures on the flange 322 of the crossmember 320 so that fasteners can be inserted through the aligned apertures. In alternate embodiments in which the brackets 330 do not have apertures, the first and second plates 332, 334 may be secured to the surfaces of the rail and crossmembers such as by the use of adhesives or welding. Further, rivets can be driven through the first or second plate 332, 334 of the bracket 330 and through the web or flange of the rail 310 or crossmember 320 to which the first or second plate 332, 334 is to be connected.

To connect a rail 410 to a crossmember 420, the brackets 430 are preferably positioned on an upper side 401 of a vehicle frame assembly, as shown in
In embodiments of the bracket 430 having apertures, the apertures 438 on the first plate 432 of the bracket 430 are situated to sit in alignment with the apertures 418 on the outer flange 414 of the rail 410. Apertures 438 on the connection section 436 of the bracket 430 are situated to sit in alignment with apertures 428 on the web 422 of the crossmember 420. Additionally, an aperture 438 on the second plate 434 of the bracket 430 is situated to sit in alignment with an aperture 418 of the tab 417 of the rail 410. Fasteners 450 as discussed above with respect to the other vehicle frame assemblies of the present invention can be inserted through the aligned apertures to secure the bracket 430 to the rail 410 and crossmember 420. In embodiments of the brackets 430 not having apertures, the bracket 430 may be secured to the rail 410 and crossmembers 420 by alternative fastening methods known in the art, such as the use of adhesives or welding.
The present invention further relates to methods for forming a vehicle frame assembly. The method includes providing at least one rail, a plurality of crossmembers, and a plurality of brackets. The rails and crossmembers may have the configuration and features as described above with respect to the vehicle frame assemblies, which may be any of the rails, crossmembers and brackets described herein in the various embodiments, including in embodiments 100, 100′, 200, 200′, 300 and 400. Further, the plurality of brackets may include any of the brackets of the type described herein having a first plate, a second plate, and a connection section for connecting the first plate and the second plate.
The rail and/or the crossmembers may be galvanized. Preferably, the rail and/or crossmembers are galvanized prior to assembling the vehicle frame assembly. The rails and crossmembers may be galvanized by spray coating or by a dipping process. It is understood that the present invention is not limited by the particular method by which the vehicle frame assembly components are galvanized. Alternate or additional coatings can also be applied to the rail and/or crossmembers prior to assembly of the vehicle frame assembly to inhibit corrosion and wear, to provide improved surface properties, and/or to improve the aesthetic appearance of the rail and crossmembers. The brackets may also be galvanized.
To assemble the vehicle frame assembly, the rail is arranged longitudinally and the crossmembers are arranged transversely to the rail. Preferably, the rail is arranged in a first plane and the crossmembers are arranged in a second plane that is parallel to the first plane. The second plane is preferably located above the first plane so that the crossmembers are stacked on the rail. However, in various alternate embodiments, the second plane may be located below the first plane so that the rail is stacked on the crossmembers.
The brackets are used to connect the rail to the crossmembers. Each bracket connects a surface of a rail to a surface of a crossmember. The brackets may be installed on an upper side and/or lower side of the vehicle frame assembly depending on the cross members employed as described above. Preferably, a first plate of the bracket engages a surface of a rail or crossmember and the second plate of the bracket engages the other of a rail or crossmember so that two corresponding members (rail and crossmember) of the assembly can be joined. In one embodiment, the bracket is configured so that the first plate is perpendicular to the second plate of the bracket, such that on an upper side of the vehicle frame assembly, the first plate can be engaged with a flange of a rail and the second plate can be engaged with a web of a crossmember. Such an embodiment is shown, for example in embodiments 100, 100′ 200 and 200′. Alternatively, the bracket configured in this manner may be installed on the lower side of the vehicle frame assembly so that the first plate can be engaged with a flange of a crossmember and the second plate can be engaged with a web of a rail.
In another embodiment, the bracket is configured so that the first plate is in a plane that is substantially parallel to a plane in which the second plate is arranged, and the first and second plates are connected by the connection section. Examples of such a bracket are shown in embodiments 300 and 400. In such embodiments, the first plate may be connected to a flange of a rail and the second plate may be connected to a flange of a crossmember as in embodiment 300 or to a flange in the form of a tab on the rail as in embodiment 400. In such embodiments, the connection section may be angled or perpendicular to the first and second plates.
In a further embodiment, the bracket is configured so that the first plate is parallel to the second plate and the connection section is perpendicular to both the first and second plates, and the first plate may be connected to an outer flange of a rail and the connection section may be connected to a web of a crossmember, and optionally the second plate may be connected to a flange in the form of a tab of the rail.
In each embodiment of the bracket, the first plate and the second plate of the bracket may be and preferably are in facing engagement with the surface of the rail or crossmember to which they are connected. Alternatively, the first plate or second plate of the bracket may be separated from the surface of the rail or crossmember, such as by a gasket or spacer. The connection sections may also be in at least partial facing engagement with a flange or web over which the connection section is positioned while bridging the area between the plates.
Regardless of the embodiment of the bracket used, fasteners of the type described herein with respect to the vehicle frame assemblies may be used to secure the brackets to the rail and crossmembers. The brackets may include apertures on the first and second plates for receiving the fasteners, and preferably the rail and crossmembers also include apertures that can be aligned with the apertures of the bracket to facilitate proper positioning of the brackets and installation of the fasteners. The first and second plates may alternatively secured to the surfaces of the rail and crossmembers by the use of adhesives or welding. Further, rivets can be driven through the first or second plate of the bracket and through the web or flange of the rail or crossmember to which the first or second plate is to be connected.
It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. It is understood, therefore, that this invention is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present invention as defined by the appended claims.
