Abstract

A vehicle has: a frame; a ground engaging member operatively connected to the frame; an engine connected to the frame; a continuously variable transmission (CVT) operatively connected to the engine; a CVT housing housing the CVT; a cockpit area defined at least in part by the frame; an air intake assembly fluidly connected to the CVT housing. The air intake assembly comprises an air intake duct body having: an air intake duct outlet in fluid communication with an inside of the CVT housing; and at least two intake duct inlets which take air in different places.

First claim

What is claimed is:

1. A vehicle comprising:
a frame;
at least one ground engaging member operatively connected to the frame;
an internal combustion engine connected to the frame;
a continuously variable transmission (CVT) operatively connected to the engine;
a CVT housing housing the CVT;
a cockpit area defined at least in part by the frame;
an air intake assembly fluidly connected to the CVT housing, the air intake assembly comprising an air intake duct body having:
an air intake duct outlet in fluid communication with an inside of the CVT housing;
at least two intake duct branches, each intake duct branch having a respective intake duct branch inlet fluidly connected to the air intake duct outlet, wherein a first intake duct branch of the at least two intake duct branches is in fluid communication with the cockpit area to fluidly connect an inside of the CVT housing with the cockpit area, the first intake duct branch having a first intake duct branch inlet.

2. The vehicle of claim 1 , further comprising a firewall between the cockpit area and the internal combustion engine, wherein the first intake duct branch is fluidly connected to the cockpit area through a firewall opening defined in the firewall.

3. The vehicle of claim 1 , wherein the first intake duct branch is connected to a rear side of the firewall.

4. The vehicle of claim 1 , wherein a second intake duct branch of the at least two intake duct branches, is disposed outside of the cockpit area, the second intake duct branch having a second intake duct branch inlet.

5. The vehicle of claim 4 , wherein the first intake duct branch inlet of the first intake duct branch has an area which is smaller than the second intake duct branch inlet of the second intake duct branch.

6. The vehicle of claim 4 , wherein the first intake duct branch has a first intake duct axis which is normal to a plane of the first intake duct branch inlet, and the second intake duct branch has a second intake duct axis which is normal to a plane of the second intake duct branch inlet, the first intake duct axis and the second intake duct axis being positioned at ≥85 degrees relative to each other.

7. The vehicle of claim 1 , wherein the second intake duct branch inlet of the second intake duct branch is aligned with an intake duct outlet axis of the air intake duct outlet, the intake duct outlet axis being normal to a plane of the air intake duct outlet.

8. The vehicle of claim 1 , wherein the first intake duct branch inlet is disposed rearward of a backrest of a driver seat in the cockpit area.

9. The vehicle of claim 8 , wherein the first intake duct branch inlet is disposed at a height below a headrest of the driver seat.

10. The vehicle of claim 1 , wherein the air intake duct body is disposed such that the first intake duct branch and the second intake duct branch are both positioned on a same side of a longitudinally extending vertical center plane of the vehicle.

11. The vehicle of claim 1 , further comprising a cap for selectively covering the first intake duct branch inlet of the first intake duct branch.

12. The vehicle of claim 1 , further comprising a grill which is attachable to the first intake duct branch inlet of the first intake duct branch.

13. The vehicle of claim 1 , wherein the first intake duct branch extends generally longitudinally towards the cockpit area.

14. The vehicle of claim 1 , wherein the second intake duct branch is configured to fluidly communicate with an environment of the vehicle through a side panel of the vehicle.

15. The vehicle of claim 1 , wherein the first intake duct branch and the second intake duct branch are configured so that, during use, air flows through the first intake duct branch and the second intake duct branch towards the air intake duct outlet.

16. An air intake assembly which is configured to be fluidly connectable to a continuously variable transmission (CVT) housing housing a CVT of a vehicle, the vehicle having:
a frame;
at least one ground engaging member operatively connected to the frame;
an internal combustion engine connected to the frame;
the CVT operatively connected to the engine;
a cockpit area defined at least in part by the frame;

the air intake assembly comprising an air intake duct body having:
an air intake duct outlet configured to be in fluid communication with an inside of the CVT housing when the air intake assembly is connected to the CVT housing;
at least two intake duct branches, each intake duct branch having a respective intake duct branch inlet fluidly connected to the air intake duct outlet, wherein a first intake duct branch of the at least two intake duct branches is configured to be in fluid communication with the cockpit area when the air intake assembly is connected to the CVT housing to fluidly connect an inside of the CVT housing with the cockpit area, the first intake duct branch having a first intake duct branch inlet.

17. The air intake assembly of claim 16 , wherein a second intake duct branch of the at least two intake duct branches is configured to be disposed outside of the cockpit area, the second intake duct branch having a second intake duct branch inlet.

18. The air intake assembly of claim 16 , wherein the second intake duct branch inlet of the second intake duct branch is aligned with an intake duct outlet axis of the air intake duct outlet, the intake duct outlet axis being normal to a plane of the air intake duct outlet.

19. The air intake assembly of claim 16 , further comprising a cap for selectively covering the first intake duct branch inlet of the first intake duct branch.

20. An air intake duct body for supplying air to a continuously variable transmission (CVT) housing housing a CVT of a vehicle, the air intake duct body comprising:
an air intake duct outlet configured to be fluidly connected to the CVT;
a first intake duct branch having a first intake duct branch inlet and a first intake duct branch outlet, and
a second intake duct branch having a second intake duct branch inlet fluidly communicating with the air intake duct outlet, the first intake duct branch outlet being defined in the second intake duct branch for fluidly communicating the first intake duct branch with the second intake duct branch,
the first intake duct branch and the second intake duct branch extending in different directions to one another.
