Description

Technical Field

[0001] The present invention relates to a device for coupling a resonator to a wheel, and more particularly, to a device for coupling a resonator to a wheel that securely couples a resonator to the wheel for improving resonant sound. Background Art

[0002] In recent years, as the size of wheels has increased with the development of vehicles, there has been a need to address the resonance sound that is generated as a side effect.

[0003] In order to solve the resonant sound, a wheel having a resonator mounted on the wheel has been disclosed.

[0004] Figure 7 is a schematic diagram showing a conventional wheel having a resonator.

[0005] refer to Figure 7 In a conventional wheel with a resonator, an insertion groove 2 is formed in a rim 1 to fix a resonator 3 to the rim 1 , and a fixing protrusion 4 is formed in the resonator 3 to correspond to the insertion groove 2 .

[0006] However, in the conventional wheel with a resonator, when a strong impact is applied to the resonator 3 during driving, cracks occur in the insertion groove portion of the rim 1 .

[0007] For example, when a wheel having a resonator runs at high speed on a bumpy road, a strong impact is applied to the inner side of the rim 1 , so that cracks occur in the insertion groove portion of the rim 1 .

[0035] like Figure 1As shown, the wheel with resonators according to various exemplary embodiments of the present invention is a wheel in which a plurality of resonators 30 are mounted on an outer circumferential surface of the wheel 100 .

[0036] The wheel 100 includes a rim 110 and a wheel disc 120. The rim 110 is an annular portion in which the resonator 30 is mounted, and a tire is mounted on the annular portion.

[0037] The resonator 30 is mounted and supported on the rim 110 via the first and second strips 10 and 20. Therefore, unlike conventional wheels having resonators, the wheel 100 does not require a separate structure (conventional insertion groove) for mounting the resonator 30, and can be applied to ordinary wheels.

[0038] refer to Figure 1 and Figure 2A The rim 110 includes a resonator mounting portion 113, and a first annular wall 111 and a second annular wall 112. The resonator 30 is mounted and arranged in the resonator mounting portion 113. The first annular wall 111 and the second annular wall 112 are integrally formed at both ends of the resonator mounting portion 113. In this case, both ends of the resonator mounting portion 113 are based on the axial direction of the rim 110.

[0039] In addition, the resonator mounting portion 113 may be formed to be flat so as to receive the bottom surface of the resonator 30 thereon.

[0040] The first annular wall 111 is formed to protrude from the outer peripheral surface of the rim 110 and to extend in the circumferential direction of the rim 110. The first annular wall 111 is formed to protrude outward from the rim 110 more than the resonator mounting portion 113 based on the radial direction of the rim 110.

[0041] The second annular wall 112 is formed to protrude from the outer peripheral surface of the rim 110 and is formed to extend in the circumferential direction of the rim 110. The second annular wall 112 is spaced apart from the first annular wall 111. The second annular wall 112 may be spaced apart from the first annular wall 111 by the width of the resonator mounting portion 113.

[0042] Based on the axial direction of the rim 110 , the first annular wall 111 may be integrally formed on one end portion of the resonator mounting portion 113 , and the second annular wall 112 may be integrally formed on the other end portion thereof.

[0043] That is, the resonator mounting portion 113 may be integrally formed with the first annular wall 111 and the second annular wall 112 to be disposed between the first annular wall 111 and the second annular wall 112 .

[0044] The plurality of resonators 30 are mounted and arranged on the outer peripheral surface of the rim 110. In other words, each of the plurality of resonators 30 is mounted in the resonator mounting portion 113 of the rim 110 and arranged along the circumferential direction of the rim 110.

[0045] The first resonator 30 a , the second resonator 30 b , the third resonator 30 c , and the fourth resonator 30 d may be mounted in the resonator mounting portion 113 .

[0046] Figure 2A and Figure 2B The configuration of the first resonator 30 a and a shape in which the first resonator 30 a is mounted in the resonator mounting portion 113 of the rim 110 are shown.

[0047] Here, we will refer to Figure 2A and Figure 2B The structure and installation shape of the first resonator 30a are mainly described. However, the second resonator 30b, the third resonator 30c and the fourth resonator 30d can be installed in the same manner as Figure 2A and Figure 2B The first resonator 30a shown is formed in the same manner and is also mounted in the resonator mounting portion 113 in the same manner as the first resonator 30a.

[0048] However, the first resonator 30a, the second resonator 30b, the third resonator 30c, and the fourth resonator 30d are mounted at different positions of the resonator mounting portion 113 so as to be arranged in the circumferential direction of the rim 110. In addition, the first resonator 30a, the second resonator 30b, the third resonator 30c, and the fourth resonator 30d can be configured to have different resonant frequencies, thereby making it possible to reduce noise of the wheel 100 over a wider frequency range.

[0049] refer to Figure 2A and Figure 2B The first resonator 30 a includes a resonator body 32 , in which a resonant cavity is formed, and a first flange 34 and a second flange 36 , which are formed on both ends of the resonator body 32 .

[0050] That is, the resonator body 32 is integrally formed with the end portion of the first flange 34 and the end portion of the second flange 36 so as to be disposed between the first flange 34 and the second flange 36 .

[0051] In this case, the resonator body 32 may be formed higher than the first and second flanges 34 and 36 based on the radial direction of the rim 110 to further protrude outward from the rim 110 .

[0052] The resonator body 32 is configured to reduce noise generated from the wheel 100 using the principle of a Helmholtz resonator.

[0053] The first resonator 30a is mounted in the resonator mounting portion 113 using the first flange 34 and the second flange 36. In other words, the first resonator 30a is coupled such that the first flange 34 and the second flange 36 are fixed to the resonator mounting portion 113.

[0054] Therefore, the first resonator 30 a is integrally formed with the first flange 34 and the second flange 36 on both side portions of the resonator body 32 to be coupled to the resonator mounting portion 113 .

[0055] The first flange 34 is formed to protrude from one edge portion of the resonator body 32 in the axial direction of the rim 110 , and is also formed to extend in the circumferential direction of the rim 110 .

[0056] That is, the first flange 34 is formed to extend from one edge portion of the resonator body 32 in a ring shape in the circumferential direction of the rim 110. In addition, the first flange 34 is formed to be pressed on the outer surface of the resonator mounting portion 113.

[0057] In addition, the bead projection groove 38 is formed so that the first flange 34 is combined with the first band 10. The bead projection groove 38 may be formed to extend in the axial direction of the rim 110.

[0058] The second flange 36 is formed to protrude from the other edge portion of the resonator body 32 in the axial direction of the rim 110 , and is also formed to extend in the circumferential direction of the rim 110 .

[0059] That is, the second flange 36 is formed to extend from the other edge portion of the resonator body 32 in a ring shape in the circumferential direction of the rim 110. In addition, the second flange 36 is formed to be pressed on the outer surface of the resonator mounting portion 113.

[0060] Furthermore, a separation prevention protrusion 22 protruding radially outward from the rim 110 may be formed on an edge portion of the second flange 36 .

[0061] The separation prevention protrusion 22 may be formed higher than the second flange 36 based on the radial direction of the rim 110 to prevent the second band 20 disposed and mounted on the second flange 36 from being separated from the second flange 36 .

[0062] When the second flange 36 is disposed in the resonator mounting portion 113 , the separation prevention protrusion 22 may be disposed adjacent to the second annular wall 112 of the rim 110 .

[0063] Meanwhile, the first strip 10 is provided to support the resonator 30 arranged on the outer peripheral surface of the resonator mounting portion 113 and fix the mounting position of the resonator 30 , and is assembled with the resonator mounting portion 113 before assembling the resonator 30 with the resonator mounting portion 113 .

[0064] refer to Figure 3 , the first belt member 10 is formed as an annular belt member extending in the circumferential direction of the resonator mounting portion 113 .

[0065] refer to Figure 4 The first band 10 is formed to have a plurality of beads 12 for combining with the first flange 34 , and the plurality of beads 12 are spaced apart from each other in the circumferential direction of the first band 10 .

[0066] The first band 10 may be provided with four beaded protrusions 12 according to the number of resonators 30 mounted on the rim 110. The four beaded protrusions 12 may be arranged at equal intervals in the circumferential direction of the first band 10.

[0067] Each bead-shaped protrusion 12 may be a portion bent from one side of the first band member 10 toward the radial inner side thereof, and formed to have a substantially U-shaped cross-section.

[0068] The first band 10 may include a portion where the beaded protrusion 12 is not formed. This portion may be referred to as a non-beaded protrusion 14. Thus, the first band 10 may be divided into the non-beaded protrusion 14 and the beaded protrusion 12. In other words, the first band 10 may include the non-beaded protrusion 14 and the beaded protrusion 12 integrally formed at the end of the non-beaded protrusion 14.

[0069] When the first ribbon 10 is assembled with the resonator mounting portion 113, the bottom surface of the beaded protrusion 12 contacts the outer surface of the resonator mounting portion 113 based on the radial direction of the first ribbon 10, and a predetermined gap (first space S1) is formed between the resonator mounting portion 113 and the non-beaded protrusion 14. The first space S1 can be formed according to the size of the beaded protrusion 12 in the radial direction thereof.

[0070] Furthermore, the first flange 34 of each resonator 30 is inserted into the first space S1 . In a state where the first flange 34 is inserted into the first space S1 , each resonator 30 is accommodated on the resonator mounting portion 113 .

[0071] For this purpose, the beaded protrusion 12 is formed to have a predetermined size and is bent to a predetermined length from the end of the non-beaded protrusion portion 14 .

[0072] When the first flange 34 of the resonator 30 is inserted into the first space S1 , the bead 12 of the first ribbon 10 is inserted into the bead groove 38 of the first flange 34 .

[0073] In other words, the first flange 34 is inserted into the first space S1 between the non-beaded portion 14 of the first ribbon 10 and the resonator mounting portion 113 , so that the beaded portion 12 of the first ribbon 10 is inserted into the beaded portion groove 38 .

[0074] In this case, the first belt 10 surrounds the outer surface of the first flange 34 inserted into the first space S1.

[0075] In a state where the first flange 34 of the resonator 30 is supported on the first band 10 , the second band 20 is mounted on the second flange 36 of the resonator 30 .

[0076] In order to simultaneously support the second flange 36 of the resonator 30 arranged in the resonator mounting portion 113 , the second band member 20 is formed in an annular shape extending in the circumferential direction of the resonator mounting portion 113 .

[0077] The second band 20 is configured to surround the outer surface of the second flange 36 in the circumferential direction of the resonator mounting portion 113 , thereby pressing the second flange 36 toward the resonator mounting portion 113 .

[0078] In other words, the second band 20 surrounds the outer peripheral surface of the second flange 36 to press the second flange 36 toward the radial inside of the resonator mounting portion 113. The resonator 30 is thereby coupled and fixed to the resonator mounting portion 113.

[0079] When the second band 20 is mounted on the second flange 36, the second band 20 is located in the space (i.e., the second space S2) between the separation prevention protrusion 22 of the second flange 36 and the resonator body 32. Thus, the second band 20 can also be prevented from being separated from the second flange 36 in the axial direction of the rim 110.

[0080] The separation prevention protrusion 22 may be formed to protrude from the outer surface of the second flange 36 toward the radially outer side thereof.

[0081] Since the second band 20 presses the second flange 36 toward the radially inner side of the rim 110 , the normal force applied by the outer peripheral surface of the rim 110 (ie, the resonator mounting portion 113 ) to the second flange 36 of the resonator 30 also increases.

[0082] Therefore, a large frictional force is generated between the resonator 30 and the rim 110 due to the second band 20 , so that the resonator 30 can be prevented from moving in the circumferential direction or the axial direction on the surface of the resonator mounting portion 113 .

[0083] Furthermore, in order to adjust the pressing force acting on the second flange 36 due to the second belt 20, one side portion of the second belt 20 may be configured in a separable and combineable structure.

[0084] refer to Figure 5 A plurality of hook-shaped members 24 may be formed on one end portion of the second belt-shaped member 20 along the circumferential direction of the second belt-shaped member 20, and a plurality of snap-fitting holes 26 configured to be hooked and fixed by the hook-shaped members 24 may be formed on the other end portion of the second belt-shaped member 20 along the circumferential direction of the second belt-shaped member 20.

[0085] Furthermore, when the second band 20 presses the second flange 36 radially inward of the rim 110 , tensile stress is applied to the second band 20 , and as the pressing force of the second band 20 increases, greater tensile stress is applied to the second band 20 .

[0086] Therefore, the second belt 20 may be configured to withstand high tensile stress, and for this purpose, the second belt 20 is made of a metal material having sufficient rigidity (eg, stainless steel).

[0087] Here, we will refer to Figures 6A to 6E The process of mounting the resonator 30 on the rim 110 is described below. Figures 6A to 6E In this order, the resonator 30 may be mounted on the resonator mounting portion 113 of the rim 110 .

[0088] First, if Figure 6A As shown, the first ribbon 10 is assembled with the resonator mounting portion 113 of the rim 110. In this case, the first ribbon 10 is located in the resonator mounting portion 113 so as to be adjacent to the first annular wall 111, and the bottom surface of the beaded protrusion 12 of the first ribbon 10 is in contact with the outer surface of the resonator mounting portion 113.

[0089] That is, the first ribbon 10 is arranged on the resonator mounting portion 113 such that the bottom surface of the bead-shaped protrusion 12 is in contact with the outer surface of the resonator mounting portion 113 .

[0090] Next, if Figure 6B and Figure 6C As shown, the first flange 34 of the first resonator 30a is inserted into the first space S1 between the non-beaded protrusion portion 14 of the first ribbon 10 and the resonator mounting portion 113. When the first flange 34 is inserted into the first space S1, the beaded protrusion 12 of the first ribbon 10 is inserted into the beaded protrusion groove 38 of the first flange 34.

[0091] That is, the first flange 34 is inserted into the first space S1 such that the bead 12 of the first band 10 is inserted into the bead groove 38 of the first flange 34 .

[0092] The beaded protrusion 12 is also configured as a guide by indicating an assembly position of the first resonator 30 a mounted on the resonator mounting portion 113 .

[0093] As described above, since the first flange 34 of the first resonator 30 a is inserted into the first space S1 , when the first resonator 30 a is coupled to the rim 110 using the second band 20 , movement and separation of the first resonator 30 a may be prevented.

[0094] The second resonator 30 b , the third resonator 30 c , and the fourth resonator 30 d are pre-mounted in the resonator mounting portion 113 in the same assembling method as the first resonator 30 a .

[0095] Next, if Figure 6D and Figure 6E As shown, the second ribbon 20 is mounted on the second flange 36 of the first resonator 30 a to couple the first resonator 30 a to the resonator mounting portion 113 .

[0096] The second band 20 is mounted on the second flange 36 of the first resonator 30a to press the second flange 36 toward the resonator mounting portion 113. In this case, the second band 20 presses the second flange 36 toward the radially inner side of the rim 110.

[0097] The second resonator 30 b , the third resonator 30 c , and the fourth resonator 30 d are mounted and coupled to the resonator mounting portion 113 in the same assembling method as the first resonator 30 a .

[0098] As described above, the resonator 30 is pre-mounted on the resonator mounting portion 113 of the rim 110 using the first band 10, and the position of the resonator 30 is fixed, and then the resonator 30 is fixedly coupled to the resonator mounting portion 113 using the second band 20. Thus, during driving, the resonator 30 can firmly resist external forces (centrifugal force and longitudinal force) acting on the resonator 30, ensuring durability and impact resistance, while also minimizing the occurrence of side effects.

[0099] Various aspects of the present invention provide the following effects through the above-mentioned means for solving the problems.

[0100] First, using the first band, a conventional insertion groove formed on the rim and intended to fix the resonator can be omitted, so that the resonator can be firmly resisted against external forces acting on the resonator during driving to ensure durability and impact resistance.

[0101] Second, a cutout portion for forming a conventional insertion groove from the outer peripheral surface of the rim can be omitted, thereby reducing the weight of the rim.

[0102] Third, a dedicated wheel including a conventional insertion groove for mounting the resonator is not required, and an ordinary wheel can be applied.

[0103] Fourth, it can ensure that the tires are easy to assemble and mass-produce.
