Abstract

In a saddle-ride type vehicle in which an intake device is arranged at a position covered by a fuel tank from above, the intake device including: an air cleaner; a connecting tube having an upstream end thereof connected to the air cleaner; a throttle device including a throttle valve and connected to a downstream end of the connecting tube; and a resonator, a curved portion bulged upward and curved in a chevron shape is formed in the connecting tube, and the resonator arranged between the fuel tank and the connecting tube is connected to the connecting tube on the air cleaner side further than a top portion of the curved portion as seen in a side view of the vehicle.

First claim

What is claimed is:

1. A saddle-ride vehicle in which a fuel tank and an engine body arranged in a lower side of the fuel tank are mounted to a body frame, and an intake device is arranged at a position covered by the fuel tank from above, the intake device including: an air cleaner; a connecting tube; a throttle device; and a resonator directly connected to the connecting tube, the connecting tube having an upstream end thereof directly connected to a purification chamber of the air cleaner and a downstream end thereof directly connected to the throttle device, the throttle device including a throttle valve,
wherein a curved portion bulged upward and curved in a chevron shape is formed in the connecting tube,
wherein the resonator is arranged between the fuel tank and the connecting tube and is connected to the connecting tube above a top most portion of the curved portion closer to an air cleaner side than the top most portion of the curved portion as seen in a side view of the vehicle,
wherein the resonator is positioned above a downwardly curved section of the connecting tube, and
wherein a connecting portion of the resonator to the connecting tube is arranged to extend upwardly of the connecting tube.

2. The saddle-ride vehicle according to claim 1 ,
wherein the body frame comprises a pair of right and left main frames, and a pair of right and left seat sub-frames connected to intermediate portions of the pair of right and left main frames, respectively, and the resonator is placed between the pair of right and left seat sub-frames and is overlapped with the seat sub-frames as seen in the side view,
wherein a recess portion receiving a part of the resonator is formed in a rear portion of a bottom plate in the fuel tank, and
wherein the upstream end of the connecting tube is arranged in a cleaner case of the air cleaner so as to overlap with a rear end of the fuel tank as seen in a plan view.

3. The saddle-ride vehicle according to claim 2 ,
wherein a rear portion of the resonator along a front-rear direction of the vehicle is arranged so as to overlap with a front portion of the cleaner case along the front-rear direction of the vehicle as seen in the plan view.

4. The saddle-ride vehicle according to claim 2 ,
wherein a fuel pump is attached to the bottom plate of the fuel tank with a lower portion of the fuel pump being protruded downward from the bottom plate, and
the resonator is arranged on a rear side of the lower portion of the fuel pump along the front-rear direction of the vehicle as seen in the side view of the vehicle.

5. The saddle-ride vehicle according to claim 2 ,
wherein the connecting portion of the resonator to the connecting tube is arranged on one of right and left sides from the top portion of the curved portion, and
an air hose extended in the front-rear direction of the vehicle from the cleaner case is arranged so as to pass above the connecting tube on an other of the right and left sides of the top portion of the curved portion.

6. The saddle-ride vehicle according to claims 3 ,
wherein the connecting portion of the resonator to the connecting tube is arranged on one of right and left sides from the top portion of the curved portion, and
an air hose extended in the front-rear direction of the vehicle from the cleaner case is arranged so as to pass above the connecting tube on an other of the right and left sides of the top portion of the curved portion.

7. The saddle-ride vehicle according to claim 4 ,
wherein the connecting portion of the resonator to the connecting tube is arranged on one of right and left sides from the top portion of the curved portion, and
an air hose extended in the front-rear direction of the vehicle from the cleaner case is arranged so as to pass above the connecting tube on an other of the right and left sides of the top portion of the curved portion.

8. The saddle-ride vehicle according to claim 2 ,
wherein a riding seat covering the air cleaner from above is arranged on a rear side of the fuel tank along the front-rear direction of the vehicle, and
a cleaner element of the air cleaner is arranged so as to be separated rearward in the front-rear direction of the vehicle from the upstream end of the connecting tube and so that a circulation direction of air extends along the front-rear direction of the vehicle.

9. The saddle-ride vehicle according to claim 3 ,
wherein a riding seat covering the air cleaner from above is arranged on a rear side of the fuel tank along the front-rear direction of the vehicle, and
a cleaner element of the air cleaner is arranged so as to be separated rearward in the front-rear direction of the vehicle from the upstream end of the connecting tube and so that a circulation direction of air extends along the front-rear direction of the vehicle.

10. The saddle-ride vehicle according to claim 4 ,
wherein a riding seat covering the air cleaner from above is arranged on a rear side of the fuel tank along the front-rear direction of the vehicle, and
a cleaner element of the air cleaner is arranged so as to be separated rearward in the front-rear direction of the vehicle from the upstream end of the connecting tube and so that a circulation direction of air extends along the front-rear direction of the vehicle.
