Abstract

A vehicle may include a CVT unit or a power source which requires ambient air. An air inlet for an air intake system coupled to the CVT unit or the power source which requires ambient air may be provided in a side of a cargo carrying portion of the vehicle. The vehicle may include a rear radius arm suspension.

First claim

What is claimed is:

1. A vehicle comprising:
a frame extending along a longitudinal axis of the vehicle;
a cargo portion supported by the frame, the cargo portion comprising a front wall;
a seat connected to the frame, the seat having a seat bottom and a seat back;
at least one ground engaging member operatively connected to the frame;
an internal combustion engine connected to the frame, the internal combustion engine being operatively connected to at least one of the at least one ground engaging member; and
an air intake assembly having at least one air intake assembly inlet and at least one air intake assembly aperture, the air intake assembly comprising a housing fluidly coupled with the at least one air intake assembly inlet, a filter positioned within the housing, and a cover coupled to the housing,
the at least one air intake assembly aperture fluidly communicating with at least one air intake port of the engine,
the at least one air intake assembly inlet being disposed rearward of the seat back and being at least partially aligned vertically with the seat back; and
at least a portion of the air intake assembly inlet is longitudinally spaced between a rearward extent of the seat back and the front wall.

2. The vehicle of claim 1 , wherein the seat is a driver seat; and the vehicle further comprises a passenger seat connected to the frame, the passenger seat having a seat bottom and a seat back, the driver and passenger seats being disposed laterally next to each other, the seat backs of the driver and passenger seats defining a space therebetween.

3. The vehicle of claim 1 , further comprising a roll over protection system, wherein the air intake assembly inlet is positioned outside of the roll over protection system.

4. The vehicle of claim 1 , further comprising an air filter fluidly communicating with the at least one air intake assembly aperture, and the air intake assembly aperture is vertically spaced from the air filter.

5. The vehicle of claim 1 , further comprising a continuously variably transmission operatively connecting the engine to the at least one ground engaging member, the continuously variable transmission comprising a drive clutch positioned on a drive clutch axis and a driven clutch positioned on a driven clutch axis.

6. The vehicle of claim 5 , wherein the air intake assembly inlet is positioned longitudinally forward relative to the vehicle of at least a portion of the continuously variably transmission.

7. The vehicle of claim 6 , wherein the air intake assembly inlet is positioned longitudinally forward relative to the vehicle of the driven clutch axis.

8. The vehicle of claim 5 , wherein the air intake assembly inlet is positioned vertically above at least a portion of the drive clutch axis.

9. The vehicle of claim 1 , further comprising an exhaust assembly comprising a muffler fluidly communicating with the engine, the muffler being disposed rearward of the air intake assembly inlet.

10. The vehicle of claim 9 , wherein the exhaust assembly further comprises an exhaust pipe; and
at least a portion of the exhaust pipe is laterally offset from the air intake assembly inlet.

11. The vehicle of claim 1 , wherein the frame includes a rear frame portion, wherein the air intake assembly inlet is positioned vertically higher than the rear frame portion.

12. The vehicle of claim 1 , further comprising a rear suspension assembly, wherein the air intake assembly inlet is positioned vertically higher than the rear suspension assembly.

13. The vehicle of claim 12 , wherein the rear suspension assembly includes a dampening member, wherein the air intake assembly inlet is positioned vertically above the dampening member.

14. The vehicle of claim 1 , wherein the at least one ground engaging member includes a rear ground engaging member, wherein the air intake assembly inlet is positioned longitudinally forward relative to the vehicle of the rear ground engaging member.
