Detailed Description
Hereinafter, preferred embodiments of the present invention that can specifically achieve the objects of the present invention will be described with reference to the drawings. In describing the present embodiment, the same structures are given the same names and the same reference numerals, and additional description thereof will be omitted.
Fig. 1 is a diagram showing a form of a vehicle wheel 1 according to a first embodiment of the present invention, and fig. 2 is a diagram showing a form of an acoustic resonator module 100 according to a first embodiment of the present invention.
As shown in fig. 1 and 2, a vehicle wheel 1 according to a first embodiment of the present invention includes a wheel disc 20, a rim 10, and a resonator module 100.
The above-mentioned spoke 20 includes: a peripheral portion; and a plurality of support portions extending radially from a center portion of the spoke in a direction along the peripheral portion.
In this case, in the present embodiment, the plurality of support portions are provided adjacently with a predetermined interval therebetween, and the number of the support portions and the interval between the support portions are not limited. That is, the support portions may have a predetermined thickness, and may be arranged in an appropriate number in consideration of the total circumferential length of the vehicle wheel 1.
The rim 10 is formed in a cylindrical shape as a whole and is formed in a shape connected to the periphery of the spoke so as to be attachable to a tire. The shape of the rim 10 is not limited, and various shapes can be formed.
The conventional matters of the above-described spoke 20 and the above-described rim 10 are matters well known to those skilled in the art to which the present invention pertains, and thus a more detailed description will be omitted.
The resonator module 100 entirely surrounds the outer peripheral surface of the rim 10 and serves to absorb resonance sound generated during vehicle traveling.
Specifically, in the present embodiment, the acoustic resonator module 100 includes: a rim contact portion 110 provided so as to surround the outer peripheral surface of the rim 10; and a resonance part 130 formed to surround at least a part of the length of the rim contact part 110, and forming a resonance space S with the rim contact part 110.
That is, the rim contact part 110 extends in the longitudinal direction to form a bottom of the resonator module 100, and the resonance part 130 is connected in the longitudinal direction of the rim contact part 110 to form the resonance space S.
In particular, in the present embodiment, the rim contact portion 110 has a total length corresponding to the circumferential length of the rim 10, and the plurality of resonance portions 130 are provided along the longitudinal direction of the rim contact portion 110. In the present embodiment, the total number of the resonance portions 130 is 3, but the present invention is not limited to this embodiment, and the number of the resonance portions may be smaller or larger.
The resonance space S may be formed in a closed shape as a whole, and a resonance band 132 partially protruding may be formed at a predetermined position of the resonance part 130 so that the resonance space S communicates with the outside. Therefore, the Resonator module 100 of the present invention can form a Helmholtz Resonator (Helmholtz Resonator) structure through the resonance band 132 and the resonance space S, and can absorb the resonance sound within the predetermined frequency range generated between the road surface and the wheel.
In this case, it is preferable that the height of the resonance band 132 is the same as the height of the resonance part 130, and the width of the resonance band 132 is smaller than the width of the resonance part 130. Further, it is preferable that the resonance band 132 is formed such that at least one of the end portions of the resonance portions 130 extends to the center portion between the adjacent resonance portions 130. However, the present invention is not limited to this, and various methods can be adopted.
The principle of the helmholtz resonator described above is well known to those skilled in the art of the present invention, and thus, a detailed description thereof will be omitted.
As described above, the resonator module 100 of the present invention includes the rim contact portion 110 that contacts so as to surround the entire periphery of the rim 10 of the vehicle wheel 1, so that the resonator module 100 itself can be stably fixed to the rim 10, and the phenomenon that the resonator module 100 is tilted by wind pressure generated by rotation of the vehicle wheel 1 can be prevented.
For example, in the case where the bottom surface of the resonance space S is exposed directly to the surface of the rim 10 in a state where it is penetrated, there is a possibility that the resonator module 100 is lifted from the rim 10 by wind pressure generated by rotation of the vehicle wheel 1, and the resonance sound cancellation effect is reduced, but the present invention can prevent this phenomenon by the rim contact portion 110.
In the present embodiment, the acoustic resonator module 100 may be configured such that the rim contact portion 110 and the acoustic resonator portion 130 are formed of an integral fiber material. Therefore, the present embodiment can reduce the weight and minimize the manufacturing cost as compared to a metal material such as plastic or aluminum.
For example, the resonator module 100 may be made of a plurality of fiber materials such as synthetic fibers, natural fibers, and carbon fibers, and specifically, in the present embodiment, the resonator module 100 is made of Polyethylene Terephthalate (PET).
The polyethylene terephthalate material is not only beneficial to realizing light weight, but also can minimize NVH (namely Noise, vibration and Harshness) value, and belongs to a recyclable environment-friendly material. Further, the polyethylene terephthalate material has excellent sound absorption performance due to its porous property, and has an advantage of being excellent in damage resistance without fear of high-strength impact.
Fig. 3 isbase:Sub>A view showingbase:Sub>A configuration in which the resonator module 100 is placed on the rim 10 of the vehicle wheel 1 according to the first embodiment of the present invention, and showsbase:Sub>A cross-sectional view taken along linebase:Sub>A-base:Sub>A of fig. 1.
As shown in fig. 3, in the present embodiment, the rim 10 includes a placement groove 12 recessed along the periphery of the outer peripheral surface of the rim 10, for placing the rim contact portion 110.
The width of the placement groove 12 may correspond to the width of the rim contact portion 110, and the side portion 131b of the resonance portion 130 may be in contact with the height difference portion 13 of the placement groove 12 in a state where the rim contact portion 110 is placed in the placement groove 12.
In this case, the protruding height of the upper portion 131a of the resonance portion 130 may be determined according to the depth of the placement groove 12.
Hereinafter, a structure of canceling resonance noise according to the present invention will be described with reference to fig. 4. Fig. 4 is a diagram showing a mode of canceling resonance sound by the resonator module according to the first embodiment of the present invention.
Resonance noise generated by friction between at least two of a road surface, a tire, and a wheel is transmitted to the resonance space S through the resonance belt 132, and the resonance noise is converted into vibrations having opposite phases in the resonance space S and is discharged to the outside of the resonance portion 130 through the resonance belt 132 again.
Therefore, the resonance sound generated between the road surface and the wheels during the running of the vehicle and transmitted to the resonance space S can be cancelled by the sound waves generated in the resonance space S in the opposite phase, and the noise generated during the running can be absorbed.
Fig. 5 is a diagram showing a form in which both end portions of the resonator module 100 according to the first embodiment of the present invention are welded.
As shown in fig. 5, in the present embodiment, the rim contact portion 110 of the resonator module 100 is formed to extend in the longitudinal direction, and the facing surfaces of the one end portion 112a and the other end portion 112b are bonded to each other while surrounding the outer peripheral surface of the rim.
That is, in the present invention, since the one end portion 112a and the other end portion 112b of the rim contact portion 110 are not overlapped with each other, but are in a state where the facing surfaces are in contact with each other, the waste of the material can be reduced, and the complicated fastening shape for connecting the one end portion 112a and the other end portion 112b of the rim contact portion 110 is not generated, and thus the manufacturing process can be simplified.
In this case, a joining method such as ultrasonic welding or Friction Stir Spot Welding (FSSW) may be used to join the one end portion 112a and the other end portion 112b of the rim contact portion 110. In the present embodiment, as shown in fig. 5, the facing surface adjacent portions of the one end portion 112a and the other end portion 112b of the rim contact portion 110 are welded by using the ultrasonic welding unit 50.
As described above, in the present invention, since the rim contact portion 110 forms the bottom portion in the resonance space S of the resonator module 100, it is not necessary to perform a separate adhesive application process for sealing, and not only does it not take time to cure the adhesive, thereby further improving productivity.
Hereinafter, other embodiments of the present invention will be described.
Fig. 6 is a diagram showing the form of the rim 10 and the resonator module 100 of the vehicle wheel 1 according to the second embodiment of the present invention.
In a second embodiment of the present invention shown in fig. 6, a receiving groove 12 is formed in a rim 10 of a vehicle wheel 1 so that the resonator module 100 can be received, as in the first embodiment.
However, with this configuration, the resonator module 100 may rotate in the circumferential direction of the rim 10 when the vehicle wheel 1 rotates.
Therefore, in the present embodiment, in order to prevent such a phenomenon, the acoustic resonator module 100 further includes a fixing portion 114 that protrudes outward in the width direction of the rim contact portion 110.
The rim 10 further includes a fixing groove 14 recessed outward in the width direction of the rim 10 from the placement groove 12, for placing the fixing portion 114.
That is, in the present embodiment, in a state where the resonator module 100 is placed on the rim 10, the rim contact portion 110 is inserted into the placement groove 12, and the fixing portion 114 is inserted into the fixing groove 14, so that the resonator module 100 can maintain a stable fixed position even when the vehicle wheel 1 is rotated.
It is needless to say that the plurality of fixing portions 114 may be provided at regular intervals or irregular intervals along the longitudinal direction of the rim contact portion 110, and the fixing grooves 14 may be formed at positions corresponding to the fixing portions 114.
Fig. 7 is a cross-sectional view showing the fixing groove 14 of the vehicle wheel 1 and the fixing portion 114 of the resonator module 100 according to the third embodiment of the present invention.
As shown in fig. 7, the resonator module 100 according to the third embodiment of the present invention includes a fixing portion 114, and a fixing groove 14 is formed in the rim 10, as in the second embodiment.
In this case, in the present embodiment, the height difference portion 15 of the fixing groove 14 formed in the circumferential direction of the rim 10 is inclined upward from the lower side by the predetermined angle θ toward the center side of the fixing groove 14.
Therefore, even when the fixing portion 114 moves in the circumferential direction of the rim 10 in the fixing groove 14 with a certain gap, the fixing portion 114 is caught by the inclined step portion 15 of the fixing groove 14 and cannot be separated outward.
Fig. 8 is a cross-sectional view showing the fixing groove 14 of the vehicle wheel 1 and the fixing portion 114 of the resonator module 100 according to the fourth embodiment of the present invention.
As in the third embodiment, the resonator module 100 according to the fourth embodiment of the present invention shown in fig. 8 includes a fixing portion 114 formed on the rim 10, and a fixing groove 14 is formed in the rim 10, and a height difference portion 15 of the fixing groove 14 formed in the circumferential direction of the rim 10 is formed to be inclined upward from a lower side by a predetermined angle θ toward the center side of the fixing groove 14.
However, the present embodiment is different from the third embodiment in that the peripheral surface 114a of the fixing portion 114 is inclined from the lower side to the upper side toward the center side of the fixing groove 14, similarly to the level difference portion 15 of the fixing groove 14.
In the present embodiment, according to the shape of the fixing portion 114, when the fixing portion 114 moves in the circumferential direction of the rim 10 within the fixing groove 14 with a certain gap, the inclined circumferential surface 114a of the fixing portion 114 completely engages with the inclined step portion 15 of the fixing groove 14 having a corresponding shape, and thus the fixing portion 114 can be stably fixed to the fixing groove 14.
Fig. 9 is a view showing a form of a vehicle wheel 1 according to a fifth embodiment of the present invention.
In contrast to the aforementioned embodiments in which the rim 10 is formed with the placement groove 12 including the recess, in the fifth embodiment of the present invention shown in fig. 9, the rim 10 includes a pair of placement projections 16 protruding along the periphery of the outer peripheral surface of the rim 10, and a placement surface 16a for placing the rim contact portion 110 of the acoustic resonator module 100 is formed in the middle by being spaced apart in the width direction of the rim 10.
That is, the rim contact portion 110 of the acoustic resonator module 100 can be fixed by the pair of placement projections 16 without moving in the width direction of the rim 10 in a state of being placed on the placement surface 16a.
In the present embodiment, the resonator module 100 may further include a fixing portion 114, and the placement projection 16 may have a through hole 17 formed at a position corresponding to the fixing portion 114 so that the fixing portion 114 is placed on the surface of the rim 10.
That is, since the passage hole 17 is formed so as not to protrude outward of the rim 10, the fixing portion 114 can be stably placed on the surface of the rim 10 without being caught by the placement projection 16.
The above description of the preferred embodiments of the present invention is provided to enable the person skilled in the art to make and use the invention in other specific embodiments than those described above, without departing from the spirit or scope of the present invention. Therefore, the above embodiments should be understood as illustrative rather than restrictive, and the invention may be modified within the scope and equivalents of the appended claims without being limited to the foregoing description.
