Description

BACKGROUND

Side-by-side recreational off-highway vehicles (“ROVs”) are quite capable in a wide variety of riding environments and situations, whether for sport or utility purposes. The ability of the vehicles to carry multiple occupants in a side-by-side seating arrangement makes them socially enjoyable to ride as well. The vehicles can be easy to enter and exit and easy to operate with controls and ergonomics somewhat similar to automobiles. However, unlike most automobiles, ROVs can be driven on harsh off-road terrain. The extent to which such terrain can be accessed depends on multiple factors, including the vehicle width, suspension, turning radius, under-carriage clearance, wheelbase, center of gravity, and power. The arrangement of these aspects and their interrelations can be important in determining the occupant ride characteristics, reliability, case of maintenance, and terrain and cargo capabilities of the ROV.

SUMMARY

According to some embodiments, an off-highway recreational vehicle is disclosed having a longitudinal centerline and including 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.

In some embodiments, the front ARB link 286 is coupled to the front upper A-arm 274, for example via a fastener such as a nut. Further, as shown at least in FIGS. 29 and 33, in some embodiments, a portion of the front ARB link 286 extends through an aperture the front anti-roll bar 282 and a portion of the front ARB link 286 extends through front link aperture 288 (FIG. 37) in the front upper A-arm 274. Although the front ARB link 286 is shown as extending through an aperture in the front upper A-arm 274 (e.g., front link aperture 288), the front ARB link 286 can, instead, be linked with the front lower A-arm 276, for example via an aperture or in any appropriate way. Further, the front ARB link 286 can be linked with the front upper A-arm 274 in any appropriate way. In some embodiments, one or more portions of the front ARB link 286 extends through one or more elastomeric members 290. In some embodiments, there are four elastomeric members 290—one on each side of the aperture in the front anti-roll bar 282 (above and below the aperture) and one on each side of the front link aperture 288 in the front lower A-arm (above and below the front link aperture 288). Thus, in some embodiments, the front suspension 272 includes eight total elastomeric members 290. In some embodiments, the elastomeric members 290 an annular-cross sectional shape. In some embodiments, the front anti-roll bar 282 connects the left side of the front suspension with the right side of the front suspension in order to reduce roll.

By way of example, in a turn, the outside suspension compresses and the vehicle 10 tends to lean to the outside. The front anti-roll bar 282 connects the left side front suspension with the right side front suspension, thereby reducing roll and increasing the effective spring rate (as compared to the same suspension without the anti-roll bar) and roll stiffness. In some embodiments, however, the vehicle 10 does not includes a front anti-roll bar 282.

In some embodiments, the front anti-roll bar 282 includes a central portion 291 (FIG. 34) and arm portions 292 (292a, 292b). As shown, the arm portions 292 extend from the central portion 291. In some embodiments, the central portion 291 undergoes torsional strain when one of the sides (left or right) of the front suspension is compressed or extended relative to the other side of the front suspension (left or right). The arm portions 292 can be rearwardly extending (as shown in FIG. 34) or forwardly extending. Further, the central portion 291 can be located inside the frame 14, outside the frame 14, above an appropriate frame member, below an appropriate frame member, or otherwise packaged in any appropriate way. As will be appreciated, the material, length of the arm portions 292, length of the central portion 291, cross-section of the central portion 291, cross-section of the arm portions 292, wall thickness (if not formed from a solid piece of material), diameter, etc., of the anti-roll bar 282 can all be selected to achieve desired suspension characteristics.

In some embodiments, the shock 294 is remotely adjustable, for example to adjust shock characteristics. In some embodiments, the shock 294 is adjustable via a mechanical adjuster (e.g., dial) or graphical user interface (GUI), which may employ a controller to adjust shock valving, etc.

In some embodiments, the damping member 280 includes a magnetorheological fluid, such that the shock characteristics can be dynamically adjusted by a microprocessor. Further still, in some embodiments, the utility vehicle 10 may not include a front anti-roll bar 282 (or rear anti-roll bar), as the microprocessor can react to changing conditions encountered by the vehicle, and vary the shock characteristics.

In some embodiments, for example as shown in FIG. 36, the front lower A-arm 276a (left hand side of the vehicle) is the same as the front lower A-arm 276b (right hand side of the vehicle), such that these front lower A-arms are interchangeable. In some embodiments, the front lower A-arm 276 is stamped from a piece of sheet metal (e.g., sheet steel). In some embodiments, the front lower A-arm is welded together from tubular steel, however, the A-arms can be formed in any suitable way and from any suitable material or materials, alloys, etc. Further, in some embodiments, the front lower A-arm 276 is formed from two or more stamped components which are welded together.

With regard to FIG. 37, in some embodiments, the front upper A-arm 274 has bearings 298 which are pressed into respective receptacles 300.

In some embodiments, the rear ARB link 326 is coupled to the rear upper A-arm 314, for example via a fastener such as a nut. As further shown, in some embodiments, a portion of the rear ARB link 326 extends through an aperture in the rear anti-roll bar 322 and a portion of the rear ARB link 326 extends through rear link aperture 328 (FIG. 47) in the rear upper A-arm 314. Although the rear ARB link 326 is shown as extending through an aperture in the rear upper A-arm 314, the rear ARB link 326 can, instead, be linked with the rear lower A-arm 316, for example via an aperture or in any appropriate way. Further, the rear ARB link 326 can be linked with the rear upper A-arm 314 in any appropriate way. In some embodiments, one or more portions of the rear ARB link 326 extend(s) through one or more elastomeric members 290, in a fashion similar to that discussed above with respect to the front anti-roll bar.

By way of example, in a turn, the outside suspension compresses and the vehicle 10 tends to lean to the outside. The rear anti-roll bar 322 connects the left side front suspension with the right side front suspension, thereby reducing roll and increasing the effective spring rate (as compared to the same suspension without the anti-roll bar) and roll stiffness. In some embodiments, however, the vehicle 10 does not includes a rear anti-roll bar 322.

In some embodiments, the rear anti-roll bar 322 includes a central portion 330 (FIG. 44) and arm portions 332 (332a, 332b). As shown, the arm portions 332 extend from the central portion 330.

Further, the central portion 330 can be located inside the frame 14, outside the frame 14, above an appropriate frame member, below an appropriate frame member, or otherwise packaged in any appropriate way. As will be appreciated, the material, length of the arm portions 332, length of the central portion 330, cross-section of the central portion 330, cross-section of the arm portions 332, wall thickness (if not formed from a solid piece of material), diameter, etc., of the rear anti-roll bar 322 can all be selected to achieve desired suspension characteristics.

In some embodiments, the rear damping member 320 includes a shock 294 and a spring 296. In some embodiments, the rear damping member 320 comprises a coil-over shock, as shown in FIGS. 39-43, 45, and 46, however, other arrangements are also contemplated. By way of example, leaf springs, coils springs, torsion springs can also be used. Further, the shock 294 can be located remotely from the spring.

In some embodiments, the shock 294 is remotely adjustable, for example to adjust shock characteristics. In some embodiments, the shock 294 is adjustable via a mechanical adjuster (e.g., dial) or graphical user interface (GUI), which may employ a controller to adjust shock valving, etc.

In some embodiments, the rear damping member 320 includes a magnetorheological fluid, such that the shock characteristics can be dynamically adjusted by a microprocessor. Further still, in some embodiments, the utility vehicle 10 may not include a front anti-roll bar 282 (or rear anti-roll bar), as the microprocessor can react to changing conditions encountered by the vehicle, and vary the shock characteristics.

In some embodiments, the rear lower A-arm 316a (left hand side of the vehicle) is the same as the rear lower A-arm 316b (right hand side of the vehicle), such that these rear lower A-arms are interchangeable. In some embodiments, the rear lower A-arms 316 is stamped from a piece of sheet metal (e.g., sheet steel).

Turning to FIG. 64B, the flywheel 410 is shown in position within the inner CVT cover 402. In some embodiments, the flywheel 410 includes a plurality of projections 432 extending radially from the flywheel 410. In some embodiments, the projections 432 are formed of the same piece of material as the flywheel 410; in some embodiments, however, the projections 432 are individual members which are attached to the flywheel 410; in still other embodiments, the projections 432 extend from an annular portion of a member that is coupled to the flywheel 410 via one or more fasteners.

With further regard to FIG. 64B, in some embodiments, a sensor 434 (e.g., magnetic pickup) is positioned adjacent to the flywheel 410 such that upon rotation of the flywheel 410 the sensor 434 detects passage of the projections 432. In this way, the engine speed is known and can be displayed on the dash of the vehicle. In this way, an operator will know how fast the engine is rotating. Such information can be displayed in revolutions per minute (RPM). In addition, the projections 432 can be arranged in a configuration that the sensor 434 can detect the position of the crankshaft of the engine. In some embodiments, an electrical lead 436 extends from the sensor 434. The electrical lead 436 can transmit a signal to the CAN bus, ECU, etc. In some embodiments, however, the signal is transmitted wirelessly to the CAN bus, ECU, etc. such that the inner CVT cover 402 does not have a CVT cover cutout 438 for the electrical lead 436. Stated differently, in some embodiments, the electrical lead 436 extends from an interior of the inner CVT cover 402 to the exterior of the inner CVT cover 402. Thus, where a signal is transmitted wirelessly from within the inner CVT cover 402, the CVT cover cutout 438 may not be necessary.

In some embodiments, the inner CVT cover 402 is coupled to the mount plate 412 (FIG. 70) via one or more fasteners. Further, in some embodiments, an inner CVT gasket 442. In some embodiments, the CVT gasket 442 resides in an inner CVT cover gasket channel 444 (FIG. 68).

With regard to FIGS. 65, 66, 68, and 69, in some embodiments, one or more of the CVT covers (e.g., inner CVT cover 402 and intermediate CVT cover 406) are coupled together via a CVT cover retainer 440. In some embodiments, the CVT cover retainer 440 comprises a snap ring. In some embodiments, the inner CVT cover 402 comprises one or more retaining tabs 446. As illustrated in FIGS. 65 and 69, the CVT cover retainer 440 is positioned between a portion of the intermediate CVT cover 406 and retaining tabs 446. In this way, the intermediate CVT cover 406 is secured to the inner CVT cover 402. In order to disassemble the intermediate CVT cover 406 from the inner CVT cover 402, in some embodiments, the CVT cover retainer 440 is expanded (in diameter) and removed from the first groove 448 (FIG. 65). Thereafter, the intermediate CVT cover 406 can be removed from the inner CVT cover 402.

With further reference to FIG. 69, in some embodiments, the inner CVT cover 402 and intermediate CVT cover 406 include ridges 450. The ridges 450 of the inner CVT cover 402 and the ridges 450 of the intermediate CVT cover 406 mate with each other in order to provide a positive interaction between the inner CVT cover 402 and the intermediate CVT cover 406, and to facilitate locating the inner CVT cover 402 and the intermediate CVT cover 406 relative to one another during assembly. Further, the ridges 450 can provide a water-tight seal between the respective CVT covers. Although the ridges 450 are shown between the inner CVT cover 402 and intermediate CVT cover 406, they can be utilized at an interface with any of the CVT covers.

Returning to FIG. 66, in some embodiments, an outer CVT gasket 452 is positioned in a second groove 454 (FIG. 68).

In some embodiments, the outer CVT gasket 452 is formed from an elastomeric material. In some embodiments, the outer CVT gasket 452 is formed from an extruded foam material or molded rubber material. In some embodiments, the outer CVT gasket 452 has a circular cross-section.

With additional reference to FIG. 66, in some embodiments, the inner CVT gasket 442 is formed from an elastomeric material. In some embodiments, the inner CVT gasket 442 is formed from an extruded foam material or molded rubber material. In some embodiments, the inner CVT gasket 442 includes a plug portion 456. As shown in FIG. 64B, the plug portion 456 fits in the CVT cover cutout 438. In some embodiments, the plug portion 456 includes a slit 458 and/or plug portion aperture 460. During assembly or disassembly of the inner CT cover 402, the slit 458 can facilitate passage of the electrical lead 436. As is shown in FIG. 70, in this way, the sensor 434 can remain coupled to the mount plate 412 (for example via an appropriate mounting bracket) upon removal of the inner CVT cover 402. Further, in some embodiments, the electrical lead 436 extends through plug portion aperture 460 when the inner CVT cover 402 is assembled to the mount plate 412. In some embodiments, the plug portion 456 is integrally formed with the inner CVT gasket 442, for example in a molding process.

As also shown in FIG. 66, in some embodiments, a CVT filter 462 (e.g., foam) is positioned within a cavity of the CVT air box 424. The CVT filter 462 can be of any suitable type, such as paper filter, foam filter, centrifugal filter, etc.

In some embodiments, air enters the CVT cover assembly 404 via CVT air box 424 and is then routed into the inner CVT cover 402. The air then flows from the inner CVT cover 402, past the inner CVT cover opening 466 and into a space between the intermediate CVT cover 406 and outer CVT cover 408 (a portion of which space is, in some embodiments, also occupied by the drive clutch 382 (FIG. 58)). Thereafter, the air flows into a narrowing region in the space between the intermediate CVT cover 406 and outer CVT cover 408 and exists through the exit port 464 (FIG. 64B) which leads into CVT exhaust duct member 422. The air is then exhausted out into the atmosphere or is used to cool an oxygen sensor or other sensor, for example as disclosed in U.S. Pub. No. 2016/0061088, titled, “Oxygen Sensor Cooling Duct,” the contents of which are herein incorporated by reference.
