Abstract

A utility vehicle has a CVT, an engine providing power to the CVT, a CVT case accommodating the CVT, front and rear wheels supporting the vehicle body frame on the ground surface and an exterior side panel supported to the vehicle body frame. The exterior side panel includes an inner wall located inside a vehicle cabin and an outer wall located outside the vehicle cabin. An intake chamber is formed between the inner wall and the outer wall of the exterior side panel. An intake opening portion is provided in the exterior side panel for introducing ambient air present around the exterior side panel to the intake chamber. The intake chamber and the CVT case are connected and communicated to each other via an intake hose.

First claim

The invention claimed is:

1. A utility vehicle having a CVT, comprising:
a vehicle body frame;
front and rear wheels supporting the vehicle body frame on the ground surface;
an engine providing power to the CVT;
a CVT case accommodating the CVT;
an exterior side panel supported to the vehicle body frame, the exterior side panel having an inner wall located inside a vehicle cabin and an outer wall located outside the vehicle cabin;
an intake chamber formed between the inner wall and the outer wall of the exterior side panel;
an intake opening portion provided in the exterior side panel for introducing ambient air present around the exterior side panel to the intake chamber; and
an intake hose connecting the intake chamber with the CVT case,
wherein the intake opening portion is provided in the outer wall.

2. The utility vehicle of claim 1 , wherein a filter is attached to the intake opening portion and a surface of the filter is substantially in flush with a wall surface of the outer wall.

3. The utility vehicle of claim 1 , wherein the intake hose is communicated to the intake chamber via a nozzle provided in the inner wall.

4. The utility vehicle of claim 1 , wherein the CVT case is disposed between the engine and the intake opening portion.

5. The utility vehicle of claim 1 , wherein an air flow in the exterior side panel flows along a vehicle front-rear direction and/or along a vehicle height direction.

6. A utility vehicle having a CVT, comprising:
a vehicle body frame;
front and rear wheels supporting the vehicle body frame on the ground surface;
an engine providing power to the CVT;
a CVT case accommodating the CVT;
an exterior side panel supported to the vehicle body frame, the exterior side panel having an inner wall located inside a vehicle cabin and an outer wall located outside the vehicle cabin;
an intake chamber formed between the inner wall and the outer wall of the exterior side panel;
an intake opening portion provided in the exterior side panel for introducing ambient air present around the exterior side panel to the intake chamber;
an intake hose connecting the intake chamber with the CVT case; and
an outlet opening provided in the exterior side panel,
wherein the intake opening portion is offset from the outlet opening in a vehicle front-rear direction and/or a vehicle height direction.
