Description
- This application claims the benefit of U.S. provisional (Number not yet assigned) filed on May 30, 2003, Express Label No. EL084750519US, and entitled TRAILER SUB-ASSEMBLY (attorney docket number 21488/04134), which is hereby incorporated by reference in its entirety.
- The invention relates generally to towable trailers, and more particularly to the assembly and manufacture of a sub-frame assembly for a trailer.
- Prior art trailers such as those used in hauling portable equipment, livestock or recreational travel trailers typically use tandem axles. The axles are typically supplied to the trailer manufacturer from the axle manufacturer. The trailer manufacturer must then install and align both axles on the trailer as well as wire or plumb the brakes of each axle assembly to the trailer. Proper alignment of the axles on the trailer can be tedious and time-consuming. Further, once the axle has been installed it is very difficult to realign, and it is often necessary to replace the entire axle if one of the wheel ends has become misaligned or damaged.
- Thus an improved axle sub-frame assembly for a trailer is desired which provides for independent alignment and realignment of each wheel, as well as easy installation of the axle sub-frame assembly by the trailer manufacturer.

FIG. 9 is a close up view of the area denoted by the circled region ofFIG. 4 and illustrating in bold the before adjustment of the toe angle and after the adjustment in dotted lines. - A first embodiment of a
sub-frame assembly 10 of the present invention is shown inFIGS. 1-9 . Thesub-frame assembly 10 is suitable for use, for example, with a trailer in the 600 to 10,000 lb class, although the invention would work for any capacity trailer. For example, the invention may be used in conjunction with utility trailers, horse/livestock trailers and camper/recreational trailers.FIG. 1 illustrates thesub-frame assembly 10 shown mounted to a utility flat bed trailer 12 (shown in dotted lines). Thesub-frame assembly 10 further includes asub-frame 30 comprised of one ormore cross-members 32 which joinframe members 34 together. The cross members may be joined to frame members by weld, bolts or other means known by one skilled in the mechanical arts. Preferably, twocross-members 32 are utilized and eachcross-member 32 is located at the desired axle location. Theframe members 34 of thesub-frame 30 are connected to aconventional trailer 12 by conventional means such as by welding, bolts or other means apparent to those skilled in the mechanical arts. - One advantage of the
subframe 30 of the invention is that thecross members 32 and theframe members 34 substantially support the axle loads in an efficient manner so that the trailer frame members may be reduced in cross-sectional size. Another advantage of thesubframe 30 is that the subframe may be prewired/preplumbed so that the electrical/hydraulic brake lines 31 of eachwheel assembly 50 are joined together in acentral hookup location 35 such as shown inFIG. 1 . - A torsion
axle stub assembly 40 is secured to thesub-assembly 10 at each of the desired wheel locations. Utilizing stub axles allows for independent adjustment of the camber and toe angles of each wheel assembly as described in more detail, below. Afirst end 42 of anaxle stub assembly 40 is inserted through alignedhole 36 offrame member 34 andhole 37 ofmounting bracket 33. Preferably, themounting bracket 33 is welded to the stub axle prior to assembly to the sub-frame. Thefirst end 42 of the axle subassembly is mounted tocross member 32 viacam bracket 38 as shown inFIG. 5 . Pivotally connected to the first end of the axle istorsion arm 44. Extending from a front face of thetorsion arm 44 is aspindle 46 for mounting a wheel andassembly 50, which preferably includes an electric or hydraulic brake (not shown). While other torsion axles can be used, the torsion axle is preferably one similar to a TORFLEX brand torsion axle from Dexter Axle, (Elkhart, Ind.) which utilizes astub shaft 41 connected to thetorsion arm 44 and which is surrounded by a plurality of rubber cylindrical members compressed between the shaft and thehousing 42. As wheels which are mounted onhub 46 oftorsion arm 44 encounter road irregularities, shock is absorbed by the rubber cylindrical members which resist rotation of thetorsion arm 44. - Another aspect of the invention is the ability to independently adjust the toe angle of each wheel assembly. As best shown in
FIGS. 4, 5 and 9, the toe angle α of eachwheel assembly 50 may be adjusted as follows. One ormore shim plates 60 may be inserted between thecross member 32 and thecam mounting bracket 38 afterbolts shim plate 60 has aligned holes orslots 62 for receivingmounting bolts Slots 62 are preferably angled in order to facilitate installation. As partially shown inFIG. 9 , as one or more shim plates are inserted between thecross member 32 and thecam mounting bracket 38 of the wheel assembly, the angle α changes so that the wheel “toes in”.FIG. 9 illustrates the assembly in solid lines prior to addition of theshim plate 60 and the assembly in dotted lines after installation of the shim plate. - Another aspect of the invention is the ability to independently adjust each camber angle β for a given wheel assembly. Further, for each wheel assembly, the camber angle β can be adjusted independently of the toe angle α. As shown in
FIGS. 6, 7 and 8, the camber angle β can be adjusted by first looseningbolts cam bolt 65 is received inoffset hole 72 ofcam member 70 andhole 39 of thecross-member 32.Cam member 70 has anexterior surface 74 from whichprojection 76 extends there from.Projection 76 is received in anelongated slot 80 of thecam mounting bracket 38 of thewheel assembly 50. Oncebolts cam bolt 65 is moved or rotated in order to rotate thecam member 70. As thecam member 70 rotates, the position of the offset mounted cam bolt with respect to thecam bracket 38 changes, resulting in an increase/decrease of the camber angle β of the wheel assembly, respectively. This action occurs in part because the cam bolt is fixed in location relative to thecross member 32. After the camber and toe angles have each been adjusted to the their desired angle, thebolts -
FIGS. 10-13 illustrate another embodiment of atrailer sub-frame assembly 200 wherein the camber angle may be adjusted. Thesub-frame assembly 200 comprisesframe members 230 joined bycross members 232. Theframe members 230 further comprise twoouter members 234 joined by aspacer member 235 which are joined together viafasteners 236. Theouter member 232 and thespacer members 235 are provided with a plurality of holes 237 to allow for the adjustment of the axle spacing. While not shown, thecross member 232 may be similarly configured to provide an adjustable width frame.FIG. 13 illustrates a close up side view of the cross-member 232 and thearm 242 of the stub axle assembly. Thecross member 232 further comprises a first set of two or more indexing holes 252,252′,252″ spaced on closely spaced increments and wherein the centers of the holes are spaced along an angular incline. The cross member may further optionally comprise a second set of indexing holes 253,253′,253″ aligned with said first set of indexing holes for each lateral location. A securing member such as a bolt, preferably aU bolt mechanism 250 is received in said indexing holes and secures thearm 242 of the stub axle assembly to thecross-member 232. In order to adjust the camber angle, the securing member orU bolt 250 is inserted into the indexing hole(s), the camber angle is measured, and the process is repeated until the desired camber angle has been set. - It is important to note that the mechanical features described above that allow the angular adjustments of toe and camber could also be used on a conventional trailer. While the invention has been shown and described with respect to specific embodiments thereof, this is for the purpose of illustration rather than limitation, and other variations and modifications of the specific embodiments herein shown and described will be apparent to those skilled in the art within the intended spirit and scope of the invention as set forth in the appended claims.
