Description:TECHNICAL FIELD
[001] This disclosure relates generally to automobiles, and more particularly to noise reducing devices used in the automobiles.
BACKGROUND
[002] One of the prominent contributors in noise pollution from vehicles, tire pavement interaction noise is a sound emitted as a result of the interaction of the tire with the road surface. Under motion, factors such as for example, tire design, road surface, vehicle speed, tire conditions, and environmental conditions may aid in increment of tire pavement noise. In electric vehicles (EVs), low rolling resistance (CRR) tires are employed to improve vehicle range, which may include shallower grooves and smoother tires. Such surface property of the tire may reduce the ability to absorb and dampen the tore pavement noise. Further, tire pavement noise is exacerbated at higher speeds and on certain road surfaces, leading to potential discomfort for occupants, compromised driving experiences, and environmental concerns, especially in urban areas. Addressing the problem of tire pavement noise is crucial not only for enhancing the comfort of vehicle occupants but also for meeting increasingly stringent noise regulations.
[003] Therefore, there is a need for a noise reducing device to efficiently reduce tire pavement noise.

[018] Reference will now be made to the exemplary embodiments of the disclosure, as illustrated in the accompanying drawings. Wherever possible, same numerals have been used to refer to the same or like parts. The following paragraphs describe the present disclosure with reference to FIGs. 1-6.
[019] As explained earlier, motion-related factors like tire design and road conditions amplify tire pavement noise, especially in electric vehicles with low rolling resistance tires. This issue, intensified at higher speeds and on certain surfaces, jeopardizes comfort, driving experiences, and environmental well-being in urban areas, necessitating urgent attention to meet noise regulations.
[020] To this end, a noise reducing device is illustrated. The noise reducing device may be equipped on at least one wheel of the vehicle, and may be configured to reduce noise emitted due to the contact of tire with the road, especially when the vehicle is in the state of motion. Now referring to FIG. 1 which illustrates a perspective view 100 of the vehicle equipped with at least one noise reducing device, in accordance with some embodiments of the present disclosure.
[021] In an embodiment vehicle may include wheels 102a, 102b, 102c, and 102d (hereinafter referred to as wheels 102) equipped with noise reducing device 104a, 104b, 104c, and 104d (hereinafter referred to as noise reducing device 104). In an embodiment, the noise reducing device 104 may be configured to encapsulate, or envelope the lower segment of a rotary member of the vehicle, preferably the lower segment of the wheel 102. Moreover, the lower segment of the wheels 102 refers to the portion of the wheel which may be proximal to the tread of the tire, i.e., proximal to the contact area of the wheel with the road.
[022] In an embodiment, the noise reducing device 104 may be configured to diminish tire pavement noise through implementation of a passive noise control mechanism. In an embodiment, the noise reducing device 104 functions as a barrier or enclosure for the lower segment of the wheel 102. In an embodiment, noise reducing device 104, acting as a barrier, may encapsulate the lower segment with a predefined gap ranging between 1.5 -3 inches from the wheel 102, and 2-4 inches from the road. Therefore, tire pavement sound waves emitted from the wheel 102 may be reverberated within the gap, and may eventually be blocked by the noise reducing device 104, or cancelled by a destructive interference. Consequently, a reduction in tire pavement noise is achieved.
[023] In an embodiment, the noise reducing device 104 may be formed as a single structure, or an assembly of one or more components such as a rigid frame or a bracket to which a noise dampening member may be attached. Now, referring to FIG. 2, which illustrates a perspective view 200 of a bracket, and referring to FIG. 3, which illustrates a perspective view 300 of the noise dampening member.

Similarly, in an embodiment, the second sub-bracket 204 may be formed by adjoining two portions, such as a first portion 210 and a second portion 212. Alternatively, the first portion 210 and the second portion 212 of the second sub-bracket 204 may be forged as a single structure.
[025] In an embodiment, in the first sub-bracket 202, the first portion 206 may include a first end 206a and a second end 206b. Further, the first end 206a may include a fastener, which may be configured to couple the sub-bracket 202 to the housing of the rotary member or the wheel 102. In an embodiment, the second portion 208 may include a proximal end 208a and a distal end 208b disposed opposite to the proximal end 208a.

As may be appreciated, the wheel 102 may be encapsulated by the C-shaped structure and free-to-move therein.
[031] In an embodiment, each of the sub-brackets 202, 204, and the linear connector 210 may include at least one receptacles 220. The at least one receptacles 220 may be distributed throughout the sub-brackets 202, 204, and the linear connector 210, and may be configured to receive a fastener. The at least one receptacles 220 may include specifically designed openings, holes, or structures where fasteners such as screws, bolts, nuts, or other connecting devices can be inserted, secured, or attached.
[032] In an embodiment, with continued reference to FIG. 3, which illustrates a perspective view of the noise-dampening member 302, as an embodiment of the present disclosure. The noise-dampening member 302 may be attached to the bracket 201, using one or more fasteners. In an embodiment, the noise reducing member may include a first segment 304, a second segment 308, a third segment 310, and a fourth segment 310. In an embodiment, the first segment 304, the second segment 308, the third segment 310, and the fourth segment 310 may be injection moulded as a single structure. Alternatively, the first segment 304 and the fourth segment 312 may be connected by an interconnecting segment 314 to resemble a C-structure similar to the bracket 201 of FIG. 2.
[033] In an embodiment, as explained earlier, the noise-dampening member 302 may be attached to the bracket 201. Particularly, the first segment 304 and the second segment 308 may be attached to the second portion 208, and the first portion 206 of the sub-bracket 202, respectively. Similarly, the third segment 310 and the fourth segment 312 may be attached to the first segment 210 and the second segment 212 of the sub-bracket 204, respectively. In an embodiment, the interconnecting segment 314 may be attached to the linear connector 216.
[034] In an embodiment, the noise-dampening member 302 may include at least one fasteners 306. The at least one fasteners 306 may correspond to the at least one receptacles 220 of the bracket 201. For example, the at least one receptacles 220 may be configured to receive the at least one fasteners 306 such to attach the noise-dampening member 302 to the bracket 210.
[035] In an embodiment, the noise-dampening member 302 may be formed as a single layered structure made of materials including but not limited to a metals such as iron and steel, or non-metals such as resin, fiber-reinforced resin, hard rubber, or elastomers capable of maintaining and retaining constant shape even after easy deformation during motion of the vehicle at high speeds. In an embodiment, the noise-dampening member 302 may be formed as a multi-layered structure including but not limited to a layer of a resin (such as ABS resin), another layer of an open porous foamed synthetic resin made of polyester, polyether, or polyurethane, and another layer of a polymer material or a metal material. Alternatively, various materials such as carpet-like fleeces, short fibers, open fabrics, knits, bristles, hair felt, wood-wool, acoustical plaster, and certain types of acoustical tiles can be employed in constructing the multi-layered structure. Irrespective of the layered structure of the noise-dampening member 302, the thickness thereof may range between 0.5 mm to 30 mm. the thickness of the noise-damping member is preferably within the range of 0.5 to 30 mm, with a more preferred range of 2 to 15 mm.
[036] An optimal thickness is essential to achieve effective noise reduction associated with tire-ground contact. If the thickness exceeds 30 mm, there is a risk that air vibrations generated at the tire-ground contact point may reflect off the ground end surface of the noise-damping member 302, resulting in an elevated sound level in a specific direction. Conversely, if the thickness is less than 0.5 mm, the noise-damping member itself may exhibit resonance, leading to inadequate suppression of air vibrations from diverging outward. The thickness of the noise-damping member may be maintained uniformly or adjusted as needed for specific requirements.
[037] In an embodiment, as explained earlier, the noise reducing device 104 may be mounted on the housing of the wheel 102. The housing may include wheel knuckle on a lower control arm, or on a suspension joint on a rear twist beam.
[038] Now referring to FIG. 4 illustrates a perspective view of a front axle 402 of a vehicle equipped with the noise-reducing device 102. In this embodiment, the noise-reducing device 104 may be mounted onto the housing of the wheels 102 on the front axle. Specifically, the fastening rods 218a and 218b are employed to secure the noise-reducing device 104 to the housing of the wheels 102 of the front axle. The housing of the wheels 102 may include a wheel knuckle 404 positioned coupled to the front axle 402. As known in the art, the wheel knuckle 404 is commonly affixed to the front axle 402 and is designed to establish a connection between the wheel 102, the tire assembly and the suspension of the vehicle. Consequently, the wheel knuckle 404 serves as a housing for the wheels 102, enabling the fastening rods 218a and 218b of the noise-reducing device 104 to be securely fastened to the wheel knuckle 504. Alternatively, the fastening rods 218a and 218b of the noise-reducing device 104 to be securely fastened to a control linkage of the front axle.
[039] In an embodiment, now referring to FIG. 5, which illustrates a perspective view 500 of the rear axle 502. As explained earlier, the noise reducing device 104 may also be connected to the housing of the wheels 102 on the rear axle 504. In this scenario, the housing may include a suspension joint 504 of the rear axle 502. In an embodiment, the noise reducing device 104 may be fastened to a suspension joint 504 connected to a rear twist beam in the rear axle 504. Particularly, the fastening rods 218a and 218b are employed to secure the noise-reducing device 104 to the suspension joint 504.
[040] In an embodiment, the assemblies of FIGs. 4-5 illustrates a structural union between the noise-reducing device 104 and the wheels 102, such that the wheel 102 may be encapsulated and free-to-move by the noise-reducing device 104. Moreover, due to the predefined gap between the wheel 102 and the noise-reducing device 104, the noise-reducing device 104 may not obstruct the wheel 102 during the motion of the vehicle.
[041] Now referring to FIG. 6 is a flow diagram 600 of method of retrofitting the noise reducing device 102, in accordance with some embodiments of the present disclosure. At step 602, one or more brackets 201 may be adjoined to a rotary member 102. In an embodiment, the fastening rods 218a and 218b are employed to secure the noise-reducing device 104 to the housing of the wheel 102. At step 504, the noise dampening member 302 may be affixed to the one or more brackets 201 to encapsulate at least one segment of the rotary member of the vehicle. This is already explained in FIGs. 1-5.
[042] With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
[043] It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
