Abstract

An off-highway recreational vehicle having a longitudinal centerline includes a frame and a rear suspension. The rear suspension includes a left A-arm, wherein the left A-arm has a pivot axis, the pivot axis being on a right-hand side of the longitudinal centerline.

First claim

What is claimed is:

1. An off-road utility vehicle having a longitudinal centerline, the vehicle comprising:
a frame, including a lower frame member; and
a rear suspension, the rear suspension comprising a left A-arm, wherein the left A-arm has a first end connected to the frame about a first pivot axis and a second end connected to frame about a second pivot axis, both the first pivot axis and the second pivot axis being on a right-hand side of the longitudinal centerline, wherein the left A-arm extends above the lower frame member.

2. The off-road utility vehicle of claim 1 , wherein the left A-arm is a lower left A-arm.

3. The off-road utility vehicle of claim 2 , wherein the rear suspension further comprises an upper left A-arm, wherein the upper left A-arm has a first end connected to the frame about a third pivot axis and a second end connected to frame about a fourth pivot axis, both the third pivot axis and the fourth pivot axis being on a left-hand side of the longitudinal centerline.

4. The off-road utility vehicle of claim 3 , wherein the lower left A-arm is longer than the upper left A-arm.

5. The off-road utility vehicle of claim 3 , further including:
a rear anti-roll bar (ARB); and
a rear ARB link having a first end coupled to the rear ARB and a second end coupled to the upper left A-arm.

6. The off-road utility vehicle of claim 5 , wherein the rear ARB link extends through an aperture in the rear ARB and through an aperture in the upper left A-arm.

7. The off-road utility vehicle of claim 1 , further comprising a right A-arm, wherein at least one of the left A-arm and right A-arm is stamped.

8. The off-road utility vehicle of claim 1 , further comprising a brake pedal assembly and a front splash panel, the brake pedal assembly comprising a fill tube, the fill tube passing through an aperture in the front splash panel.

9. The off-road utility vehicle of claim 8 , wherein brake pedal assembly further includes a first reservoir located rearward of the front splash panel and a second reservoir located forwardly of the front splash panel, wherein the first reservoir is fluidly connected to the second reservoir via the fill tube, wherein the fill tube slopes downwardly from the second reservoir to the first reservoir.

10. The off-road utility vehicle of claim 1 , further comprising one or more doors, wherein the doors comprise at least one composite material.

11. The off-road utility vehicle of claim 10 , wherein at least one composite material has ballistic protection.

12. The off-road utility vehicle of claim 1 , further comprising at least one seat bottom and at least one seat back, wherein the seat bottom is stowable behind the at least one seat back.

13. The off-road utility vehicle of claim 1 , further comprising a continuously variable transmission (CVT) cover assembly, the CVT cover assembly including an inner CVT cover, an intermediate CVT cover, and an outer CVT cover, wherein a drive clutch and a driven clutch are located between the outer CVT cover and the intermediate CVT cover, and wherein a flywheel is located between the engine and the inner CVT cover.

14. The off-road utility vehicle of claim 13 , wherein the outer CVT cover is coupled to the intermediate CVT cover via one or more CVT cover fasteners that are releasable by hand, wherein the outer CVT cover is removable from the intermediate CVT cover without the use of tools.

15. The off-road utility vehicle of claim 1 , further comprising a column-shifter.

16. The off-road utility vehicle of claim 1 , wherein the first pivot axis and the second pivot axis are coaxial with one another.

17. The off-road utility vehicle of claim 1 , wherein the frame comprises:
a rear joining frame member, a rear upper cross member, and a rear lower frame member, the rear joining frame member joining the rear upper cross member and the rear lower frame member, wherein the rear joining frame member has a sloped portion.

18. The off-road utility vehicle of claim 17 , further comprising a cargo box assembly including a cargo box, wherein the cargo box has a first configuration and a second configuration, and wherein, when the cargo box is in the second configuration, the sloped portion provide clearance for the cargo box.

19. The off-road utility vehicle of claim 18 , wherein the cargo box assembly further comprises a tilt release member and a tilt release catch and the frame comprises a latch pin having a square cross section, the tilt release catch configured to latch with the latch pin when the cargo box is in the first configuration.

20. The off-road utility vehicle of claim 17 , wherein the frame further comprises rear upper rear-suspension support member and at least one longitudinal intermediate rear frame member, wherein the at least one longitudinal intermediate rear frame member is joined to the rear joining frame member and the rear upper rear-suspension support member is joined to the at least one longitudinal intermediate rear frame member.

21. The off-road utility vehicle of claim 20 , further comprising a muffler, the muffler being supported by the rear upper rear-suspension support member.

22. The off-road utility vehicle of claim 1 , further comprising a roll-over protection structure (ROPS) comprising a connection member having a first connection portion, a second connection portion, and a third connection portion.
