Abstract

A resonator structure of a saddle-ride vehicle includes a head box that includes a head pipe defining a handlebar steering axis and that forms an intake passage through which air is guided from a front of the vehicle into an inside of the vehicle when the vehicle is traveling, an air cleaner box that is connected to the head box and allows the air guided through the intake passage to be taken into a power unit of the vehicle, and a resonator that forms a resonator chamber configured to reduce an air intake noise. The resonator chamber is formed continuous to the intake passage inside the head box.

Claims

1. A resonator structure of a saddle-ride vehicle comprising:

a head box that includes a head pipe defining a handlebar steering axis and that forms an intake passage through which air is guided from a front of the vehicle into an inside of the vehicle when the vehicle is travelling;

an air cleaner box that is connected to the head box and allows the air guided through the intake passage to be taken into a power unit of the vehicle; and

a resonator that forms a resonator chamber configured to reduce an air intake noise,

wherein the resonator chamber is formed continuous to the intake passage inside the head box.

2. The resonator structure of the saddle-ride vehicle according to claim 1, wherein the resonator is integrally molded with the head box as a single member.

3. The resonator structure of the saddle-ride vehicle according to claim 2, wherein the single member is a forged metal member.

4. The resonator structure of the saddle-ride vehicle according to claim 1,

wherein the head box includes a partition between the resonator chamber and the intake passage so the partition separates the resonator chamber and the intake passage, and

a communication hole through which the resonator chamber and the intake passage communicate is formed in the partition.

5. The resonator structure of the saddle-ride vehicle according to claim 4, wherein the air cleaner box is disposed at a rear side of the head box, an intake hole is provided at a front portion of the air cleaner box, and the intake hole is disposed rearward of the communication hole.

6. The resonator structure of the saddle-ride vehicle according to claim 1, wherein the resonator is symmetrically disposed at each of left and right sides of the head box.

7. The resonator structure of the saddle-ride vehicle according to claim 1, wherein

the head box forms two of said intake passage through which air is guided from a front of the vehicle into an inside of the vehicle when the vehicle is traveling, said intake passages are disposed at each of left and right sides of the head box,

two of said resonator are disposed at each of right and left sides within the head box, the resonators form respective ones of the resonator chamber which are continuous to respective ones of the intake passages inside the head box, and

a pair of left and right intake holes are provided at the front portion of the air cleaner box and receive the air guided through respective ones of the intake passage.

8. The resonator structure of the saddle-ride vehicle according to claim 1, wherein an upper-lower length of the resonator is shorter than an upper-lower length of the head pipe in a direction along the handlebar steering axis.

9. The resonator structure of the saddle-ride vehicle according to claim 8, wherein the resonator extends rearward of the head pipe and below an upper surface of the head pipe.

10. The resonator structure of the saddle-ride vehicle according to claim 1, wherein the resonator forms an inner wall of the head box and an outer wall of the head pipe.

11. The resonator structure of the saddle-ride vehicle according to claim 1, wherein the resonator and a side frame of the saddle-ride vehicle are integrally molded with the head box.

12. A saddle-ride vehicle comprising:

a head box that includes a head pipe defining a handlebar steering axis and that forms an intake passage through which air is guided from a front of the vehicle into an inside of the vehicle when the vehicle is travelling;

an air cleaner box that is connected to the head box and allows the air guided through the intake passage to be taken into a power unit of the vehicle; and

a resonator that forms a resonator chamber configured to reduce an air intake noise,

wherein the resonator chamber is formed continuous to the intake passage inside the head box.

13. The saddle-ride vehicle according to claim 12, wherein the resonator is integrally molded with the head box as a single member.

14. The saddle-ride vehicle according to claim 13, wherein the single member is a forged metal member.

15. The saddle-ride vehicle according to claim 12,

wherein the head box includes a partition between the resonator chamber and the intake passage so the partition separates the resonator chamber and the intake passage, and

a communication hole through which the resonator chamber and the intake passage communicate is formed in the partition.

16. The saddle-ride vehicle according to claim 15, wherein the air cleaner box is disposed at a rear side of the head box, an intake hole is provided at a front portion of the air cleaner box, and the intake hole is disposed rearward of the communication hole.

17. The saddle-ride vehicle according to claim 12, wherein an upper-lower length of the resonator is shorter than an upper-lower length of the head pipe in a direction along the handlebar steering axis, and the resonator extends rearward of the head pipe and below an upper surface of the head pipe.
