Definitions
- the invention relates to vehicle frames and in particular to frame hangers for mounting axle/suspension systems on the vehicle frame. More particularly, the present invention is directed to a hanger formed of aluminum which efficiently attaches to and forms a part of an aluminum vehicle frame, whereby the overall weight and cost of the frame is reduced as compared to aluminum frames which utilize steel hangers, and further whereby the aluminum hanger efficiently reacts loads emanating from the axle/suspension system during operation of the vehicle.
- a typical leading or trailing arm air-ride axle/suspension system is mounted on and depends from the frame of a vehicle by a pair of rigid frame hangers located adjacent to one of the ends of the axle/suspension system, and by a pair of flexible air springs disposed at the other end of the system.
- the conventional hanger is a fabricated welded steel box-like yoke structure that captures the bushing assembly end of a respective one of the pair of suspension arms or beams of the axle/suspension system, using a pivot pin or bolt.
- the steel hanger in turn is either welded or bolted to another component of the vehicle frame, depending on the material used for the frame.
- the steel hanger typically is welded on, whereas for frames formed of aluminum, such as semi-trailer tanker trailers, the hanger must be bolted on because of the impracticality of welding together dissimilar metals.
- steel hangers satisfactorily mount an axle/suspension system on steel or aluminum vehicle frames and successfully react loads emanating from the system during over-the-road operation of the vehicle, as noted immediately above, the steel hanger must be bolted rather than welded to an aluminum vehicle frame.
- a pair of heavy mounting plates are disposed between the hanger and the frame to serve as an interface, which adds unwanted weight and cost to the vehicle.
- Such complicated bolt mounting also lessens the efficiency of the distribution of loads being transferred from the axle/suspension system, through the hanger, and into the other components of the vehicle frame.
- Objectives of the present invention include providing a hanger for aluminum vehicle frames which also is formed of aluminum, but which has a design sturdy enough to react loads emanating from the axle/suspension system, and further which mounts simply and directly to the other frame components for efficient transfer of such loads from the hanger into the other frame components.
- the aluminum frame hanger for axle/suspension systems of the present invention including an aluminum vehicle frame having a frame hanger for suspending a suspension assembly of an axle/suspension from the vehicle frame, the frame including a pair of transversely spaced longitudinally extending main members and a plurality of cross members extending between and interconnecting the main members, the axle/suspension system including a pair of transversely spaced suspension assemblies, each one of the pair of suspension assemblies including a longitudinally extending beam, the beams of the pair of suspension assemblies capturing a transversely extending axle having at least one wheel mounted on each end of the axle, the beams each including at one of its ends a bushing assembly for pivotally mounting the beam on the frame hanger, wherein the improvement comprises an integral frame hanger which substantially surrounds and laterally supports the bushing assembly, so that the hanger reacts lateral loads and other loads transferred from the axle/suspension system into the frame during operation of the vehicle, without

- Fig. 2 is an enlarged fragmentary side view, with portions broken away and in section and hidden parts represented by dashed lines, showing the manner of attachment of the prior art steel hanger to the aluminum portion of the vehicle frame;
- Fig. 2A is a fragmentary bottom view of the components shown in Fig. 2, and showing in dashed lines a suspension beam mounted on the hanger;
- Fig. 3 is a perspective view similar to Fig. 1 , but showing aluminum hangers of the present invention suspending the axle/suspension systems from the aluminum frame;
- Fig. 4 is a bottom perspective view of the assembly of parts shown in Fig. 3;
- Fig. 5 is an enlarged exploded perspective view of the aluminum hanger of the present invention utilized in Figs. 3 and 4;
- Fig. 6 is a perspective view of the hanger of Fig. 5 shown in an assembled state
- Fig. 7 is an enlarged fragmentary bottom view, with hidden parts represented by dashed lines, showing the manner of welded attachment of the hanger of Fig. 6 to the other components of the vehicle frame as represented in Figs. 3 and 4.
- a vehicle frame is indicated generally at 10 and is shown in Fig. 1 .
- Frame 1 0 represented in Fig. 1 is a portion of an aluminum tanker trailer frame of a semi-trailer.
- Tanker trailer frame 1 0 includes a pair of main members 1 1 , a plurality of front and rear cross members 1 2A and 1 2B, respectively, and front and rear pairs of hangers 14A and 1 4B, respectively, for suspending axle/suspension systems 1 5A and 1 5B, respectively, from the tanker trailer frame.
- Trailer frame 1 0 utilizing prior art hangers 1 4A and 1 4B now will be described so that the general environment in which the hanger of the present invention is used can be best understood.
- tanker trailer frame 1 0 The components of tanker trailer frame 1 0 are formed of aluminum unless otherwise specified.
- Frame 1 0 is manufactured from aluminum because reduced weight is an important consideration in tanker trailer applications, and also because the type of tank (not shown) typically attached to the frame is formed of aluminum and it is easier to attach like metals to one another when constructing a vehicle.
- Each main member 1 1 of frame 1 0 is an elongated, generally C-shaped beam.
- the open portion of each main member 1 1 is opposed to the open portion of the other main member and faces inboard relative to frame 1 0.
- Main members 1 1 are connected to each other in a transversely spaced-apart parallel relationship by cross members 1 2A and 1 2B, which extend between and are perpendicular to the main members.
- each cross member 1 2A, B nests in the open portion of a respective one of main members 1 1 , and is secured therein by any suitable means such as welding or mechanical fastening. More particularly, each cross member 1 2A, B also is a generally C-shaped beam, with its nested ends each being coped (Figs. 1 and 2) so that the bottom surface of each of the cross members is in the same horizontal plane as the bottom surface of main members 1 1 .
- Cross members 1 2A and 1 2B are longitudinally spaced-apart.
- trailer frame 1 0 is completed by front and rear hangers 14A and 1 4B, respectively, which are each attached to and depend from respective ones of the aluminum frame main members 1 1 and certain ones of the plurality of cross members 1 2A and 1 2B, respectively, disposed adjacent to the hangers to aid in mounting axle/suspension systems 1 5A and 1 5B, respectively, on the frame.
- hangers 1 4A and 1 4B typically are formed of steel rather than the aluminum used to form the other components of frame 1 0, because the hangers are subjected to severe loadings during operation of the vehicle.
- axle/suspension systems 1 5A, 1 5B are transferred from axle/suspension systems 1 5A, 1 5B, through hangers 1 4A, 1 4B, respectively, and into main members 1 1 and cross members 1 2A and 1 2B, respectively, of frame 1 0.
- a plurality of aligned pairs of openings are formed in plates 1 6 and 1 7 and a fastener 1 8 in turn is passed through each one of the aligned pairs of openings to effectively mount steel hangers 14A and 1 4B on the other structural components of aluminum frame
- Each axle/suspension system 1 5A, B includes a generally identical pair of suspension assemblies 31 , with each one of the pair of suspension assemblies being suspended from a respective one of the hangers of the pair of hangers 14A, B, respectively.
- Each suspension assembly 31 includes a suspension arm or beam 32 which is pivotally mounted at one of its ends on its respective hanger 1 4A, B via a bushing assembly 35, in a usual manner.
- Bushing assembly 35 forms a part of beam 32 and includes an outer metal tube 36 which is captured within its respective hanger 1 4A, B.
- bushing assembly 35 includes other components which are hidden in the drawings and/or not fully described herein, including an elastomeric bushing mounted in tube 36, an inner metal tube, and a pivot bolt.
- An air spring 33 is suitably mounted on and extends between the upper surface of the other end of beam 32 and its respective main member 1 1 at a location directly beneath a respective one of cross members 1 2A, B.
- a shock absorber 34 extends between and is mounted on suspension beam 32 and its respective hanger 1 2A, B.
- Each suspension assembly 31 also includes an air brake (not shown).
- An axle 37 extends between and is captured in the pair of suspension beams 32 of each axle/suspension system 1 5A, B. Wheels (not shown) are mounted on each end of axle 37.
- hangers 1 4A, B formed of steel, and additional mounting structures including heavy steel plate 1 6 and aluminum plate 1 7, which plates each are typically from about 3/8 of an inch to about 1 /2 inch thick, and fasteners 1 8, all used to facilitate mounting of steel hangers 14A, B on other components of aluminum frame 1 0, adds unwanted weight and cost to the vehicle.
- plates 1 7, 1 6 introduces high fatigue stresses at the welded attachment points of each of the aluminum plates to a respective one of main members 1 1 and its respective pair of cross members 1 2A, B, and at the welded attachment points of each of the steel plates to its respective prior art hanger 1 4A, B, respectively.
- fastened plates 1 6 and 1 7 cantilever loads, particularly in tension, in relation to spaced-apart fasteners 1 8, and such loads pass through the plates from its respective axle/suspension system 1 5A, B and hanger 14A, B, respectively, as those loads are passing into main members 1 1 and cross members 1 2A, B, respectively.
- Such cantilevering of loads causes movement and separation of plates 1 6, 1 7, and in turn induces high fatigue stresses and possible failure on the welds that attach the plates to hangers 1 4A, B, and to frame members 1 1 and cross members 1 2A, B, respectively.
- a hanger that is welded directly to a vehicle frame is much more efficient in evenly and uniformly transferring loads from the hanger into the other components of the frame.
- hangers 1 4A, B are formed of a robust steel material, due to its rigid, fabricated welded box-like design that captures outer metal tube 36 of beam bushing assembly 35, the prior art steel frame hanger is not completely efficient in transferring loads from the hanger and into the other components of aluminum vehicle frame 1 0.
- frame hangers 1 4A, B each must be augmented with various gussets, flanges, and the like each referred to as 38, to make the hangers more efficient in the transfer of such loads.
- Such additional structure also adds unwanted weight and cost to the vehicle.
- prior art aluminum hangers generally are reduced in weight over steel hangers and can be welded directly to the other components of the vehicle frame, thus eliminating add-on structure such as plates 1 6 and 1 7 and fasteners 1 8, such prior art aluminum hangers also have several disadvantages.
- prior art aluminum hangers generally have mimicked the design of the steel hangers shown in Figs. 1 and 2.
- Hanger 24A, B of the present invention replaces prior art steel hanger 1 4A, B. Since the components of axle/suspension systems 1 5A, B which hangers 24A, B, respectively, support are the same as shown in Figs. 1 -2 and described hereinabove, only differences between present invention hanger 24A, B and prior art hanger 14A, B, as well as changes to certain other components of frame 1 0 due to the use of the present invention hanger, will be described immediately below.
- Hanger 24A, B is shown in Figs. 3-7, with Figs. 3, 4 and 7 showing the hanger as a component of frame 1 0'. Since frame 1 0' differs from frame 1 0 of Fig. 1 only in that frame 1 0' uses present invention hanger 24A, B rather than prior art hanger 14A, B, and certain reinforcing gussets, flanges, and the like are removed from the frame due to the use of the present invention hanger, all of the similar components of the frame and axle/suspension systems 1 5A', B' shown in Figs. 3, 4 and 7 are identified by a prime ' but use the same identifying number as the parts shown in Figs. 1 and 2.
- Each hanger 24A, B is formed of aluminum and includes a generally U-shaped base 25 formed with an opening 26 for receiving suspension beam 32'.
- U-shaped base 25 further includes a pair of inboardly upwardly extending wings 42, which are especially important for aiding in the transfer of lateral or side loads from hanger 24A, B and into other components of frame 1 0', as will be described in greater detail below.
- a generally inverted U-shaped support member 27 nests in U-shaped base 25 adjacent to and straddling opening 26 and is attached to the base preferably by welds (not shown), and especially aids in reacting vertical loads, as well as side loads.
- support member 27 The vertical portions of support member 27 are formed with transversely aligned openings 28 for receiving the pivot bolt which passes through and pivotally attaches beam bushing assembly 35' to hanger 24A, B.
- a pair of vertically disposed, horizontally spaced alignment guides 44 each are located on the outboard vertical sidewall of support member 27 to aid in the alignment of axle/suspension system 1 5A', B', as is well-known to the art and literature.
- a bent plate 29 extends between and is welded to the inboard vertical sidewall of support member 27 and to wings 42 of U- shaped base 25 to provide additional support to the structure primarily for reacting side loads.
- a generally oval-shaped connection member 30 nests in U-shaped base 25 and rests on the upper horizontal surface of support member 27, and is welded to the U-shaped base and the support member to complete the structure of aluminum hanger 24A, B.
- Hanger 24A, B is attached to the other components of frame 10' by a continuous weld 40 disposed at the interface of the uppermost edge of connection member 30 and the bottom surface of its respective main member 1 1 ' (Fig. 7) .
- Each wing 42 of U-shaped base 25 is welded to a respective one of cross members 1 2A', B' (Figs. 4 and 7) to complete the attachment of hangers 24A, B and the structure of trailer frame 1 0' incorporating the hangers of the present invention.
- hanger 24A, B enable its formation from a lightweight metal such as aluminum, rather than a heavier metal such as steel.
- Beam opening 26 and U-shaped base 25, as well as support member 27, enable hanger 24A, B to generally completely and continuously surround the pivotal attachment area of beam 32' to the hanger, thus providing enhanced structural support, which is a design feature quite different than the design of conventional prior art fabricated steel hangers 1 4A, B which have several components welded together into a more open box-like yoke structure (Fig. 2A) .
- U-shaped base 25 welds not only to its respective main member 1 1 ' via connection member 30, but to a respective pair of cross members 1 2A', B' via wings 42.
- U-shaped base 25 also allows for elimination of a heavy C-channel frame cross brace between each of the front and rear pairs of hangers 24A and 24B, respectively, which braces were commonly utilized in prior art hangers 1 4A, B (not shown in Fig. 1 ).
- certain other add-on structural components used in frame 1 0 to assist prior art hanger 1 4A, B in reacting loads are not required in frame 1 0' due to the structure of hanger 24A, B.
- the design of hanger 24A, B also allows for simpler weld attachment to the other frame components than is found in prior art aluminum hangers due to the use of continuous weld 40.
- hanger 24A, B also eliminates the need of costly coping of each end of cross members 1 2A', B' to which hanger 24A, B is attached, such as shown in Fig. 2 for prior art hanger 1 4A, B.
- hanger 24A, B of the present invention because of its formation from aluminum, is lightweight, and eliminates complicated attachment assemblies which heretofore have been needed to successfully attach steel hangers to aluminum frames. ln addition, the simplified yet efficient structure enables hanger 24A, B to successfully react loads passing through the hanger from its associated axle/suspension system 1 5A', B' and into the other components of frame 1 0', without the use of additional gussets, flanges or the like on hanger 24A, B or frame 1 0'.
- aluminum hanger 24A, B of the present invention incorporates a novel structural design which enables the hanger to react various loads passing through the hanger during operation of the vehicle, and especially lateral or side loads.
- Previous attempts to solve this problem in an aluminum structure using conventional hanger design required utilization of extremely thick side plates, reinforcement bosses, gussets and the like, both on the hanger and vehicle frame, which defeated the purpose of a lightweight aluminum hanger, despite the fact that such hangers could be welded directly to the other components of the vehicle frame.
- the present invention in particular reacts lateral loads with success due especially to support member 27, bent plate 29, and wings 42 of U-shaped base 25 which attach to cross members 1 2A', B' and direct the side loadings into the cross members and other components of the frame such as main members 1 1 '.
- hanger 24A, B of the present invention can be used in connection with tapered beams utilizing reduced-size bushings or, alternatively, can be designed for use with conventional- sized beams utilizing conventional-size bushings by widening the hanger.
- hanger 24A, B of the present invention also could be utilized on other types of aluminum semi-trailer frames or even on aluminum movable subframes for semi-trailers.
- Hanger 24A, B also could be utilized on aluminum vehicle frames other than semitrailer frames.
- the improved aluminum frame hanger for axle/suspension systems is simplified, provides an effective, safe, inexpensive, and efficient structure which achieves all the enumerated objectives, provides for eliminating difficulties encountered with prior steel and aluminum hanger structures, and solves problems and obtains new results in the art.
