Abstract

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 shaft is positioned to extend the wheelbase relative to the input shaft, or in a second position in which the output shaft is positioned in vertical alignment with the input shaft.

First claim

The invention claimed is:

1. An adjustable portal box assembly for selectively mounting a wheel to an off road vehicle in either one of two positions, the assembly comprising a mounting plate and a portal box;
wherein said mounting plate is mountable to the suspension of the off road vehicle;
wherein said portal box is mountable to said mounting plate;
wherein said portal box includes an input shaft opening for an input shaft, and an output shaft opening for an output shaft,
wherein said portal box is mountable to the mounting plate in either of two positions, namely:
a first position in which the output shaft is positioned below and forward of said input shaft when the assembly is adapted for mounting a forward wheel, and in which the output shaft is positioned below and rearward of said input shaft when the assembly is adapted for mounting a rearward wheel, and
a second position in which the output shaft is positioned below and in vertical alignment with the input shaft.

2. The assembly of claim 1 wherein said mounting plate includes a first set of holes for mounting the portal box to the mounting plate in its first position, and a second set of holes for mounting the portal box to the mounting plate in its second position, and wherein said portal box includes a single set of holes for mounting the portal box to the mounting plate in either said first position or said second position.

3. The assembly of claim 1 wherein said portal box includes a first set of holes for mounting the portal box to the mounting plate in said first position, and a second set of holes for mounting the portal box to the mounting plate in said second position.

4. The assembly of claim 1 wherein said mounting plate includes mounting brackets adapted to mount the assembly to the suspension of the off road vehicle.

5. The assembly of claim 1 wherein said portal box includes a rear cover and a front cover.

6. The assembly of claim 1 wherein said rear cover includes holes for mounting the portal box to the mounting plate in either said first position or said second position.

7. The assembly of claim 1 wherein said front cover includes holes for mounting the portal box to the mounting plate in either said first position or said second position.

8. The assembly of claim 1 wherein the portal box includes gears for directly or indirectly transferring power from the input shaft to the output shaft, and wherein said gears reduce the speed of rotation of the output shaft relative to the speed of rotation of the input shaft.

9. The assembly of claim 2 wherein the gears include a first gear mounted directly or indirectly to the input shaft, and a second gear mounted directly or indirectly to the output shaft.

10. An adjustable portal box assembly for mounting a wheel to an off road vehicle in a lifted and extended wheelbase position, the assembly comprising a mounting plate and a portal box;
wherein said mounting plate is mountable to the suspension of the off road vehicle;
wherein said portal box is mountable to said mounting plate;
wherein said the portal box includes an input shaft opening for an input shaft, and an output shaft opening for an output shaft,
wherein said 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 said input shaft when the assembly is adapted for mounting a forward wheel, and in which the output shaft is positioned below and rearward of said input shaft when the assembly is adapted for mounting a rearward wheel.

11. The assembly of claim 10 wherein said mounting plate includes mounting brackets adapted to mount the assembly to the suspension of the off road vehicle.

12. The assembly of claim 10 wherein said portal box includes a rear cover and a front cover.

13. The assembly of claim 10 wherein said rear cover includes holes for mounting the portal box to the mounting plate.

14. The assembly of claim 10 wherein said front cover includes holes aligned with said rear cover holes for mounting the portal box to the mounting plate.

15. The assembly of claim 10 wherein the portal box includes gears for directly or indirectly transferring power from the input shaft to the output shaft, and wherein said gears reduce the speed of rotation of the output shaft relative to the speed of rotation of the input shaft.

16. The assembly of claim 13 wherein the gears include a first gear mounted directly or indirectly to the input shaft, and a second gear mounted directly or indirectly to the output shaft.

17. An adjustable portal box assembly for selectively mounting a wheel to an off road vehicle in either of two positions, the assembly comprising a mounting plate, a portal box, an input shaft, and an output shaft;
wherein said mounting plate is mountable to the suspension of the off road vehicle;
wherein said portal box is mountable to said mounting plate;
wherein said portal box includes an input shaft opening for receiving said input shaft, and an output shaft opening for receiving said output shaft,
wherein said input shaft is connected to said vehicle and extends into the portal box assembly through said input shaft opening, and wherein said output shaft extends outward from the portal box assembly through said output shaft opening;
wherein said portal box is mountable to the mounting plate in a first position in which the output shaft is positioned below and forward of said input shaft when the assembly is adapted for mounting a forward wheel, and below and rearward of said input shaft when the assembly is adapted for mounting a rearward wheel, and in a second position in which the output shaft is positioned below and in vertical alignment with said input shaft.
