- one aspect of the present invention relates to an adjustable portal box assembly for selectively mounting a wheel to an off road vehicle in either of two positions.
- the inventive assembly comprises a mounting plate and a portal box.
- the mounting plate is mountable to the suspension of an off road vehicle, and the portal box is mounted to the mounting plate.
- the portal box includes an input shaft opening for an input shaft, and an output opening for an output shaft.
- the portal box is mountable to the mounting plate in either of two positions, namely: 1) a position in which the output opening is positioned below and vertical alignment with the input shaft opening; and 2) a position in which the output opening is positioned below and forward of the input shaft opening when the assembly is adapted for mounting a forward wheel, or below and rearward of the input shaft opening when the assembly is adapted for mounting a rearward wheel, in both cases extending the wheelbase of the vehicle compared to the wheelbase when the output opening is in vertical alignment with the input shaft opening.
- each mounting plate is mountable to either a front wheel or a rear wheel, or optionally either. Similarly, each mounting plate is mountable to either a left wheel or a right wheel, or optionally either. Accordingly, each mounting plate may be a front left plate, or a front right plate, or a rear left plate, or a rear right plate, or a front plate that is usable on either the left or the right, or a rear plate that is usable on either the left or the right, or a left plate that is usable on either the front or the rear, or a right plate that is usable on either the front or the rear, or a universal plate that is usable on any wheel. Potentially other combinations are also available depending on the specifics of how the plate is to be mounted to the vehicle.
- the mounting plate portion of the inventive portal box assembly includes an opening for receiving an input shaft.
- the input shaft is generally centered in the input shaft opening.
- the portal box portion of the inventive portal box assembly includes an opening for extending an output shaft.
- the output shaft is generally centered in the output shaft opening.
- the mounting plate is adapted such that the portal box is mountable to the mounting plate in a position in which the output shaft is positioned below and forward of the input shaft when the assembly is adapted for mounting a front wheel, or below and rearward of the input shaft when the assembly is adapted for mounting a rear wheel.
- This “extended wheelbase” position extends the wheelbase of the vehicle compared to the wheelbase when the output shaft is in vertical alignment with the input shaft.
- the mounting plate is adapted such that the portal box is mountable to the mounting plate in either a “vertically aligned” or an “extended wheelbase” position.
- the output shaft In the “vertically aligned” position the output shaft is positioned directly above the input shaft, and is not forward or rearward of the input shaft. The wheelbase of the vehicle is thus substantially the same as the wheelbase when the portal box is not installed.
- the output shaft In the “extended wheelbase” position the output shaft is positioned below and forward of the input shaft when the assembly is adapted for mounting a front wheel, or below and rearward of the input shaft when the assembly is adapted for mounting a rear wheel. In both cases this extends the wheelbase of the vehicle compared to the wheelbase when the output shaft is in vertical alignment with the input shaft.
- the mounting plate is adapted such that the portal box is mountable to the mounting plate only in an “extended wheelbase” position in which the output shaft is positioned below and forward of the input shaft when the assembly is adapted for mounting a front wheel, or below and rearward of the input shaft when the assembly is adapted for mounting a rear wheel.
- the mounting plate includes at least one set of holes for mounting the portal box to the mounting plate in its first position, and at least one set of holes for mounting the portal box to the mounting plate in its second position.
- the two sets of holes are the same, so that the portal box may be mounted to the mounting plate in either the “vertically aligned” or “extended wheelbase” second position.
- the portal box includes a first set of holes for mounting the portal box to the mounting plate in its “vertically aligned” position, and a second and different set of holes for mounting the portal box to the mounting plate in its “extended wheelbase” position.
- the mounting plate includes hardware (e.g., mounting brackets) adapted to mount the assembly to the suspension of the off road vehicle, and for connecting components such as steering arms and the like.
- the mounting hardware may be separable from, or incorporated into, the mounting plate.
- the portal box portion of the inventive assembly preferably includes a rear wall, side walls, and a front wall (cover), at least one of which is preferably removable to allow access to the inside of the box.
- Holes for mounting the portal box to the mounting plate in either its first position or its second position are preferably included in the rear cover of the portal box, and the front cover may also include holes for mounting the portal box to the mounting plate in either its first position or its second position.
- the portal box preferably includes gears for directly or indirectly transferring power from the input shaft to the output shaft.
- the gears also reduce the speed of rotation of the output shaft relative to the speed of rotation of the input shaft, thus providing the amount of gear reduction necessary to run larger tires.
- the gears typically include a first gear mounted directly or indirectly to the input shaft, and a second gear mounted directly or indirectly to the output shaft.
- the adjustable portal box assembly is effective for mounting a wheel to an off road vehicle in a lifted and extended wheelbase position.
- That assembly also includes a mounting plate and a portal box, with the mounting plate being mountable to the suspension of an off road vehicle, and the portal box being mountable to said mounting plate.
- the portal box is mountable to the mounting plate in an extended wheelbase position in which the output opening is positioned below and forward of said input shaft opening when the assembly is adapted for mounting a forward wheel, and in which the output opening is positioned below and rearward of said input shaft opening when the assembly is adapted for mounting a rearward wheel.
- the portal box is not mountable to the mounting plate in a position in which the output opening is vertically aligned with the input shaft opening.

Abstract
Description
- This application claims priority from U.S. patent application Ser. No. 16/717,210, filed Dec. 19, 2019, which claims the benefit of U.S. Provisional Application No. 62/781,829, filed Dec. 19, 2018; the entire contents of both prior applications, and of related U.S. patent application Ser. No. 17/348,913, being hereby incorporated herein by reference.
- The present invention relates generally to portal wheel ends for lifting the wheels of an off road vehicle such as an all-terrain vehicle (ATV) or a utility task vehicle (UTV), and more particularly to a portal box and associated hardware end that provides wheel base extension in addition to lift.
- Portal boxes are known to ATV and UTV enthusiasts for providing increased ground clearance, or lift, and the low gearing needed for bigger tires. Such boxes are typically mounted to an ATV/UTV by first mounting a backing plate to the suspension of the vehicle, and by then mounting the portal box to the backing plate. U.S. Pat. No. 8,985,264 to Shirley is one example of such a device.
- The backing plate of Shirley, and of the other portal box mounting systems known to the art, have the input shaft positioned directly above the output shaft. This provides the greatest degree of lift, while minimizing the torque on the mounting assembly.
- Applicant has determined that alternative mounting options may provide benefits not provided by prior art assemblies. A need therefore exists for a mounting assembly for a portal box in which the box may be mounted to the mounting plate in an alternative position. The present invention addresses that need.
- Briefly describing one aspect of the present invention, there is provided an adjustable portal box assembly for selectively mounting a wheel to an off road vehicle in either of two positions. The assembly includes a mounting plate mountable to the suspension of an off road vehicle, and a portal box is mountable to the mounting plate. The portal box includes an input shaft opening for an input shaft, and an output opening for an output shaft. The portal box is mountable to the mounting plate in a first position in which the output opening is positioned to extend the wheelbase relative to the input shaft opening, or in a second position in which the output opening is positioned in vertical alignment with the input shaft opening.
- In another aspect of the present invention there is provided an adjustable portal box assembly for selectively mounting a wheel to an off road vehicle in a standard, lifted position, or in an extended, lifted position. The assembly comprises a mounting plate and a portal box, with the mounting plate being mountable to the suspension of an off road vehicle, and the portal box being mountable to the mounting plate. The portal box includes an input shaft opening for an input shaft, and an output opening for an output shaft, and is mountable to the mounting plate in either of two positions. In the first position the output opening is positioned below and forward of said input shaft opening when the assembly is adapted for mounting a forward wheel, and the output opening is positioned below and rearward of said input shaft opening when the assembly is adapted for mounting a rearward wheel. In the second position the output opening is positioned below and not forward of said input shaft opening when the assembly is adapted for mounting a forward wheel, and the output opening is positioned below and not rearward of said input shaft opening when the assembly is adapted for mounting a rearward wheel.
- In another aspect of the present invention there is provided an adjustable portal box assembly for mounting a wheel to an off road vehicle in a lifted and extended wheelbase position. The assembly comprises a mounting plate and a portal box. The mounting plate is mountable to the suspension of an off road vehicle, and the portal box is mountable to said mounting plate. The portal box includes an input shaft opening for an input shaft, and an output opening for an output shaft. The portal box is mountable to the mounting plate in an extended wheelbase position in which the output opening is positioned below and forward of said input shaft opening when the assembly is adapted for mounting a forward wheel, and in which the output opening is positioned below and rearward of said input shaft opening when the assembly is adapted for mounting a rearward wheel.
- In another aspect of the present invention there is provided an adjustable portal box assembly for selectively mounting a wheel to an off road vehicle in either of two positions. The assembly comprises a mounting plate, a portal box, and input shaft, and an output shaft. The mounting plate is mountable to the suspension of an off road vehicle, and the portal box is mountable to said mounting plate. The portal box includes an input shaft opening for receiving the input shaft, and an output opening for receiving the output shaft, and the input shaft is operably connected to the vehicle and extends into the portal box assembly through the input shaft opening, and the output shaft extends outward from the portal box assembly through said output opening.

It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the described device, and such further applications of the principles of the invention as illustrated therein, being contemplated as would normally occur to one skilled in the art to which the invention relates.
- As indicated above, one aspect of the present invention relates to an adjustable portal box assembly for selectively mounting a wheel to an off road vehicle in either of two positions. The inventive assembly comprises a mounting plate and a portal box. The mounting plate is mountable to the suspension of an off road vehicle, and the portal box is mounted to the mounting plate. As is known to the art, the portal box includes an input shaft opening for an input shaft, and an output opening for an output shaft. The portal box is mountable to the mounting plate in either of two positions, namely: 1) a position in which the output opening is positioned below and vertical alignment with the input shaft opening; and 2) a position in which the output opening is positioned below and forward of the input shaft opening when the assembly is adapted for mounting a forward wheel, or below and rearward of the input shaft opening when the assembly is adapted for mounting a rearward wheel, in both cases extending the wheelbase of the vehicle compared to the wheelbase when the output opening is in vertical alignment with the input shaft opening.
- Each mounting plate is mountable to either a front wheel or a rear wheel, or optionally either. Similarly, each mounting plate is mountable to either a left wheel or a right wheel, or optionally either. Accordingly, each mounting plate may be a front left plate, or a front right plate, or a rear left plate, or a rear right plate, or a front plate that is usable on either the left or the right, or a rear plate that is usable on either the left or the right, or a left plate that is usable on either the front or the rear, or a right plate that is usable on either the front or the rear, or a universal plate that is usable on any wheel. Potentially other combinations are also available depending on the specifics of how the plate is to be mounted to the vehicle.
- The mounting plate portion of the inventive portal box assembly includes an opening for receiving an input shaft. The input shaft is generally centered in the input shaft opening.
- The portal box portion of the inventive portal box assembly includes an opening for extending an output shaft. The output shaft is generally centered in the output shaft opening.
- In all embodiments of the present invention the mounting plate is adapted such that the portal box is mountable to the mounting plate in a position in which the output shaft is positioned below and forward of the input shaft when the assembly is adapted for mounting a front wheel, or below and rearward of the input shaft when the assembly is adapted for mounting a rear wheel. This “extended wheelbase” position extends the wheelbase of the vehicle compared to the wheelbase when the output shaft is in vertical alignment with the input shaft.
- In some embodiments, the mounting plate is adapted such that the portal box is mountable to the mounting plate in either a “vertically aligned” or an “extended wheelbase” position. In the “vertically aligned” position the output shaft is positioned directly above the input shaft, and is not forward or rearward of the input shaft. The wheelbase of the vehicle is thus substantially the same as the wheelbase when the portal box is not installed. In the “extended wheelbase” position the output shaft is positioned below and forward of the input shaft when the assembly is adapted for mounting a front wheel, or below and rearward of the input shaft when the assembly is adapted for mounting a rear wheel. In both cases this extends the wheelbase of the vehicle compared to the wheelbase when the output shaft is in vertical alignment with the input shaft.
- In some embodiments, the mounting plate is adapted such that the portal box is mountable to the mounting plate only in an “extended wheelbase” position in which the output shaft is positioned below and forward of the input shaft when the assembly is adapted for mounting a front wheel, or below and rearward of the input shaft when the assembly is adapted for mounting a rear wheel.
- The mounting plate includes at least one set of holes for mounting the portal box to the mounting plate in its first position, and at least one set of holes for mounting the portal box to the mounting plate in its second position. In some embodiments the two sets of holes are the same, so that the portal box may be mounted to the mounting plate in either the “vertically aligned” or “extended wheelbase” second position. In other embodiments the portal box includes a first set of holes for mounting the portal box to the mounting plate in its “vertically aligned” position, and a second and different set of holes for mounting the portal box to the mounting plate in its “extended wheelbase” position.
- The mounting plate includes hardware (e.g., mounting brackets) adapted to mount the assembly to the suspension of the off road vehicle, and for connecting components such as steering arms and the like. The mounting hardware may be separable from, or incorporated into, the mounting plate.
- The portal box portion of the inventive assembly preferably includes a rear wall, side walls, and a front wall (cover), at least one of which is preferably removable to allow access to the inside of the box.
- Holes for mounting the portal box to the mounting plate in either its first position or its second position are preferably included in the rear cover of the portal box, and the front cover may also include holes for mounting the portal box to the mounting plate in either its first position or its second position.
- The portal box preferably includes gears for directly or indirectly transferring power from the input shaft to the output shaft. The gears also reduce the speed of rotation of the output shaft relative to the speed of rotation of the input shaft, thus providing the amount of gear reduction necessary to run larger tires. The gears typically include a first gear mounted directly or indirectly to the input shaft, and a second gear mounted directly or indirectly to the output shaft.
- In another embodiment the adjustable portal box assembly is effective for mounting a wheel to an off road vehicle in a lifted and extended wheelbase position. That assembly also includes a mounting plate and a portal box, with the mounting plate being mountable to the suspension of an off road vehicle, and the portal box being mountable to said mounting plate. The portal box is mountable to the mounting plate in an extended wheelbase position in which the output opening is positioned below and forward of said input shaft opening when the assembly is adapted for mounting a forward wheel, and in which the output opening is positioned below and rearward of said input shaft opening when the assembly is adapted for mounting a rearward wheel. However, in this embodiment the portal box is not mountable to the mounting plate in a position in which the output opening is vertically aligned with the input shaft opening.
- Referring now to the drawings,
FIG. 1 is a front perspective view of a portal box assembly according to one embodiment of the present invention.Assembly 100 includes a mountingplate 101 and aportal box 102.Portal box 102 includes portalbox side wall 126 andportal box cover 124.Output shaft 104 extends fromportal box 102. -
FIG. 2 is a rear perspective view of portions of the portal box assembly ofFIG. 1 . Portal box 120 includes portalbox side wall 126, andoutput shaft 104 extends from the box.Input shaft gear 105 is connected to inputshaft 103, andoutput shaft gear 106 is connected tooutput shaft 104. Linkinggear 107 connectsinput shaft gear 105 tooutput shaft gear 106. -
FIG. 3 is an exploded view of the portal box assembly ofFIG. 1 . Mountingplate 101 includes an input shaft opening, andinput shaft 103 extends through that input shaft opening.Portal box 102 includesrear wall 125,side wall 126, andfront cover 124.Output shaft opening 109 is provided infront cover 124 ofportal box 102, andoutput shaft 104 extends throughoutput shaft opening 109.Rear plate 110 facilitates mountingbox 102 to a vehicle. -
FIG. 4 is a front perspective view of the portal box assembly ofFIG. 1 with the front portal box cover removed.Input shaft gear 105, linkinggear 107, andoutput shaft gear 107 are visible when the cover is removed. -
FIG. 5 is a front elevational view of the portal box assembly ofFIG. 1 , showing the box attached to the mounting plate in a position in whichoutput opening 109 is positioned below and vertically aligned with theinput shaft opening 108. While not shown in the drawing,input shaft 103 extends backward from, and perpendicular to, the plane of the page. Similarly,output shaft 104 extends forward from, and perpendicular to, the plane of the page. Line L passes through the center of input shaft 103 (and presumably through the center of input shaft opening 108) and the center of output shaft 104 (and presumably through the center of output shaft opening 109) when viewed from this perspective.Portal box 102 is mounted to mountingplate 101 such that output shaft 104 (and presumably output shaft opening 109) is vertically aligned with input shaft 103 (and presumably input shaft opening 108). Whenoutput shaft 104 is vertically aligned withinput shaft 103, line L is substantially perpendicular to any line passing through the plane of the “ground” when the assembly is properly mounted to a vehicle resting on a flat, horizontal, planar surface. InFIG. 5 , one such line is illustrated by line G, with the angle α1 between line L and line G being substantially 90°. -
FIG. 6 is a front elevational view of the portal box assembly ofFIG. 1 , showing the box attached to the mounting plate in a position in which the output opening is positioned forward of the input shaft opening. InFIG. 6 ,portal box 102 is attached to mountingplate 101 in a position in whichoutput opening 109 is positioned below and forward ofinput shaft opening 108 when the assembly is mounted to a front wheel. Here too, while not shown in the drawing,input shaft 103 extends backward from, and perpendicular to, the plane of the page,output shaft 104 extends forward from, and perpendicular to, the plane of the page, and line L passes through the center of input shaft 103 (and presumably through the center of input shaft opening 108) and the center of output shaft 104 (and presumably through the center of output shaft opening 109). In this case though,portal box 102 is mounted to mountingplate 101 such that output shaft 104 (and presumably output shaft opening 109) is not vertically aligned with input shaft 103 (and presumably input shaft opening 108). Instead,output shaft 104 is forward ofinput shaft 103, and line L is not substantially perpendicular to the plane of the “ground” when the assembly is properly mounted to a vehicle resting on a flat, horizontal, planar surface. In the illustrated embodiment, line L forms and angle α2 that is approximately 15° from perpendicular with respect to line G. -
