Description

Technical Field

[0001] This application relates to the field of automobile manufacturing technology, and in particular to a wheel assembly and a transport vehicle. Background Technology

[0002] When a vehicle is driving on the road, the friction between the wheels and the ground generates significant noise, which can penetrate the vehicle and negatively impact the experience for the driver and passengers. Existing vehicles typically install noise-reducing components such as resonators on the wheel rims to absorb this noise.

[0003] However, the traditional connection between the rim and the resonator is unstable, and the position of the resonator on the rim is not stable. Utility Model Content

[0004] This application provides a wheel assembly and a transport vehicle, which aims to solve the problem of unstable connection between the existing wheel rim and resonator.

[0005] In a first aspect, this application provides a wheel assembly, which includes a rim and a resonator. The rim includes a mounting body and a limiting part. The mounting body is provided with a mounting groove, which is arranged around the outer periphery of the mounting body. The limiting part is connected to the groove wall of the mounting groove, and the corresponding part of the limiting part and the mounting groove form a receiving cavity. The resonator is installed in the receiving cavity.

[0006] In some optional embodiments, the wheel assembly further includes a connecting mechanism, which includes a first connecting portion and a second connecting portion. The first connecting portion is disposed on at least one side of the accommodating cavity in the width direction; the second connecting portion is disposed on at least one side of the resonator in the width direction, and the second connecting portion is detachably connected to the first connecting portion.

[0007] In some optional embodiments, multiple limiting parts are provided, and the multiple limiting parts form multiple receiving cavities with the mounting groove; multiple resonators are provided, and the multiple resonators correspond one-to-one with the multiple receiving cavities, with each resonator installed in the corresponding receiving cavity.

[0008] In some optional embodiments, two resonators are provided, which are spaced 90° or 180° apart in the circumferential direction of the rim.

[0009] In some optional embodiments, three resonators are provided, with adjacent resonators spaced 120° apart circumferentially on the rim.

[0010] In some optional embodiments, the first connecting part is a groove structure and the second connecting part is a retractable protrusion structure; or, the first connecting part is a retractable protrusion structure and the second connecting part is a groove structure.

[0011] In some optional embodiments, the limiting part includes an abutting part and a connecting part. The abutting part is spaced apart from the groove of the mounting groove, and the connecting part is connected between the abutting part and the mounting body. The connecting part and the abutting part form a relief groove, which communicates with the mounting groove. The corresponding parts of the relief groove and the mounting groove form a receiving cavity.

[0012] In some optional embodiments, the first connecting portion is disposed at the connecting portion.

[0013] In some optional embodiments, the limiting part is provided with a first mounting part, and the mounting body is provided with a second mounting part, and the first mounting part and the second mounting part are detachably fixedly connected.

[0014] Secondly, this application provides a transport vehicle, which includes a vehicle housing and wheel assemblies as described above, with multiple wheel assemblies spaced apart on the side of the vehicle housing facing the ground.

[0015] This application provides a wheel assembly including a rim resonator. The resonator is mounted on the rim to reduce noise. In this embodiment, the rim includes a mounting body and a limiting part. The mounting body has a mounting groove that surrounds the outer periphery of the mounting body. The limiting part is connected to the peripheral structure of the mounting groove, and corresponds to and covers a portion of the mounting groove. The mounting groove and the limiting part form a receiving cavity, and the resonator is mounted in the receiving cavity.

[0016] In this embodiment, the resonator is inserted into the receiving cavity, causing the rim structure to cover the resonator's outer periphery. This restricts the resonator's large-scale movement in the rim's axial and radial directions, resulting in a more stable position of the resonator on the rim and ensuring its stable mounting. In practical applications, the wheel assembly rotates rapidly, and the resonator is subjected to centrifugal force. The limiting part effectively restricts the resonator's radial movement on the rim. When the tire is deflated, the limiting part is located between the tire and the resonator, protecting the resonator from damage and preventing fragments from damaging the rim and tire.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0028] Please see Figure 1This application provides a wheel assembly 100 and a transport vehicle 1000 equipped with the wheel assembly 100. In this embodiment, the transport vehicle 1000 is a means of transportation for transporting goods or carrying people, and the transport vehicle 1000 may include cars, trucks, etc. In some other embodiments, the transport vehicle 1000 may also include aircraft, etc. In this embodiment, the transport vehicle 1000 may include a vehicle shell 800, which forms the external outline of the transport vehicle 1000 and can define various functional spaces, such as a cargo hold, a cockpit, a passenger cabin, an engine compartment, etc.

[0029] In this embodiment, the transport vehicle 1000 also includes multiple wheel assemblies 100, which are generally located on the ground-facing side of the vehicle housing 800 to support it. The wheel assemblies 100 are spaced apart to ensure the vehicle housing 800 is relatively stable. In this embodiment, the transport vehicle 1000 can be a car, with four wheel assemblies 100. Every two wheel assemblies 100 form a wheel set, and the two wheel sets are arranged alternately along the car's direction of travel. In other embodiments, the transport vehicle 1000 can be a truck or other vehicle with a large total mass. In such embodiments, a wheel set may include four, six, or other wheel assemblies 100, and the number of wheel sets may be three, four, or more.

[0030] In this embodiment, the wheel assembly 100 may include a rim 10 and a tire 30. The tire 30 is mounted on the rim 10, and both sides of the tire 30 in its axial direction are respectively sealed to both sides of the rim 10 in its axial direction to define a sealed inflation space. By inflating the inflation space, the internal air pressure of the tire 30 is adjusted so that the internal air pressure of the tire 30 is close to a preset air pressure value so that it can travel on the road surface. In other embodiments, the tire 30 and the rim 10 may have other matching methods. For example, the wheel assembly 100 may also include an inner tube, which is located between the tire 30 and the rim 10. Inflating the inner tube supports the tire 30.

[0031] Please see Figure 2 In this embodiment, the wheel assembly 100 may include a wheel rim 10 and a resonator 20 assembled together. The resonator 20 is detachably mounted on the wheel rim 10. In this embodiment, the resonator 20 has a cavity, which is connected to the outside through a narrow neck tube. The resonator 20 has a natural frequency. When the incident sound wave is the same as the natural frequency of the resonator 20, resonance occurs, the air column movement intensifies, the amplitude and velocity reach their maximum, the damping is also the maximum, and the sound energy is consumed the most, thereby achieving a sound absorption effect.

[0032] Please see Figure 2 and Figure 3In this embodiment, the rim 10 includes a mounting body 11 and a limiting part 12. The mounting body 11 is the main structure of the rim 10 and is generally a rotating body about the axis of the rim 10. In this embodiment, a mounting groove 111 is provided on the outer periphery of the mounting body 11. The mounting groove 111 extends along the outer periphery of the mounting body 11. The limiting part 12 is connected to the groove wall (or the peripheral structure of the mounting groove 111) and corresponds to a portion of the groove of the mounting groove 111. The limiting part 12 covers the portion of the groove of the mounting groove 111. The limiting part 12 and the portion of the groove of the mounting groove 111 form a receiving cavity 13. The inner wall of the portion of the groove of the mounting groove 111 and the side surface of the limiting part 12 facing the mounting body 11 together constitute the inner wall of the receiving cavity 13.

[0033] Please see Figure 2 and Figure 3 In this embodiment, the receiving cavity 13 is a space communicating with the outside, and the resonator 20 is installed inside the receiving cavity 13. In this embodiment, the receiving cavity 13 is generally in the shape of a through hole, and extends circumferentially along the rim 10 to form a curved space. The resonator 20 extends circumferentially along the rim 10, and the resonator 20 has an overall curved structure to adapt to the receiving cavity 13. In this embodiment, the receiving cavity 13 has two ports, which are arranged alternately along the circumferential direction of the rim 10. The ports allow the receiving cavity 13 to communicate with the outside of the receiving cavity 13, so as to facilitate the installation or removal of the resonator 20. In other embodiments, the receiving cavity 13 may have only one port.

[0034] In this embodiment, with the resonator 20 inserted into the receiving cavity 13, the opposite sides of the receiving cavity 13 along the axial direction of the rim 10 (hereinafter referred to as "rim 10 axial direction") can restrict the resonator 20 from moving significantly along the rim 10 axial direction. The limiting part 12 and the mounting body 11 are respectively located on opposite sides of the resonator along the radial direction of the rim 10 (hereinafter referred to as "rim 10 radial direction"), and can also restrict the resonator 20 from moving significantly along the radial direction of the rim 10. In this embodiment, at least a portion of the structure of the resonator 20 is embedded in the mounting groove 111, and the mounting groove 111 body is relatively stable, effectively restricting the movement of the resonator 20.

[0035] In summary, this application provides a wheel assembly 100, which includes a rim 10 and a resonator 20. The resonator 20 is mounted on the rim 10 and reduces noise. In this embodiment, the rim 10 includes a mounting body 11 and a limiting part 12. The mounting body 11 has a mounting groove 111, which surrounds the outer periphery of the mounting body 11. The limiting part 12 is connected to the peripheral structure of the mounting groove 111. The limiting part 12 corresponds to and covers a portion of the mounting groove 111. The mounting groove 111 and the limiting part 12 form a receiving cavity 13, and the resonator 20 is mounted in the receiving cavity 13.

[0036] In this embodiment, the resonator 20 passes through the receiving cavity 13, so that the structure of the rim 10 covers the outer periphery of the resonator 20. This restricts the resonator 20 from moving significantly in the axial and radial directions of the rim 10, making the position of the resonator 20 on the rim 10 more stable, thus achieving stable mounting of the resonator 20 on the rim 10. In practical applications, when the wheel assembly 100 rotates rapidly, the resonator 20 is subjected to centrifugal force, and the limiting part 12 can effectively restrict the radial movement of the resonator 20 on the rim 10. When the tire 30 is deflated, the limiting part 12 is located between the tire 30 and the resonator 20. The limiting part 12 can protect the resonator 20 from being crushed and also prevent fragments of the resonator 20 from damaging the rim 10 and the tire 30.

[0037] In this embodiment, the wheel assembly 100 also includes a connecting mechanism (not shown in the figure). The connecting mechanism is connected between the rim 10 and the resonator 20 so that there is a connection between the rim 10 and the resonator 20. Based on the limiting of the receiving cavity 13, the connecting mechanism can further restrict the resonator 20 from moving in the circumferential direction of the rim 10 (hereinafter referred to as "circumferential direction of the rim 10").

[0038] Please see Figure 4 , Figure 5 and Figure 6 In this embodiment, the rim 10 is provided with a first connecting portion 1221, which is disposed on the inner wall of the receiving cavity 13. The resonator 20 is provided with a second connecting portion 221. When the resonator 20 passes through the receiving cavity 13, the second connecting portion 221 is located in the receiving cavity 13, and the second connecting portion 221 is detachably connected to the first connecting portion 1221. In this embodiment, the inner wall of the receiving cavity 13 has the function of restricting the movement of the resonator 20. The first connecting portion 1221 is disposed inside the receiving cavity 13, which makes the connection relationship between the first connecting portion 1221 and the second connecting portion 221 more stable, and the connection relationship between the first connecting portion 1221 and the second connecting portion 221 can effectively restrict the resonator 20 from moving upward around the rim 10.

[0039] Please see Figure 4 and Figure 5 In this embodiment, the first connecting portion 1221 is disposed on at least one side of the receiving cavity 13 in the width direction; the second connecting portion 221 is disposed on at least one side of the resonator 20 in the width direction. In this embodiment, the width direction of the receiving cavity 13, the width direction of the resonator 20, and the axial direction of the rim 10 are approximately the same. In this embodiment, the receiving cavity 13 has at least one first connecting portion 1221 on each opposite side in the width direction, and the resonator 20 has at least one second connecting portion 221 on each opposite side in the width direction. Multiple second connecting portions 221 correspond one-to-one with multiple first connecting portions 1221, and each second connecting portion 221 is detachably connected to its corresponding first connecting portion 1221. With this configuration, the resonator 20 experiences uniform force on its opposite sides in the width direction, making the connection between the resonator 20 and the rim 10 more stable, and thus making the positional state of the resonator 20 more stable.

[0040] Please see Figure 4 and Figure 6 In this embodiment, the first connecting part 1221 and the second connecting part 221 are detachably connected by a fitting and engaging manner, so that the resonator 20 and the rim 10 can form a connection relationship through their own structure, reducing the number of parts in the wheel assembly 100 and simplifying the structure of the wheel assembly 100.

[0041] Specifically, in this embodiment, the first connecting portion 1221 is a groove structure. For ease of description, the groove-shaped first connecting portion 1221 is defined as an embedding groove, which communicates with the receiving cavity 13. In this embodiment, the resonator 20 includes a noise reduction body 21, which can form the cavity and neck tube mentioned above. The second connecting portion 221 is connected to the noise reduction body 21 and is a protrusion structure. The second connecting portion 221 can extend and retract relative to the noise reduction body 21, and its state relative to the noise reduction body 21 can be switched to adapt to disassembly and assembly requirements. As an example, when the resonator 20 passes through the receiving cavity 13, the second connecting portion 221 protrudes relative to the noise reduction body 21 and is embedded in the embedding groove to establish a detachable connection between the resonator 20 and the rim 10. As a second example, the resonator 20 gradually detaches from the receiving cavity 13 under the action of external force, and the second connecting part 221 retracts relative to the noise reduction body 21 in a direction away from the embedding groove to detach from the embedding groove, thereby releasing the detachable connection between the resonator 20 and the rim 10.

[0042] Please see Figure 7 and Figure 8In this embodiment, the noise reduction body 21 is provided with a receiving groove 211, which communicates with the outside. In this embodiment, the resonator 20 also includes an insert 22, one end of which is movably connected to the inner wall of the receiving groove 211, and the other end is provided with a second connecting portion 221. The insert 22 is movably embedded in the receiving groove 211, so that the second connecting portion 221 can extend or retract relative to the noise reduction body 21.

[0043] During the installation of the resonator 20, when the resonator 20 passes through the receiving cavity 20 and the insert 22 is not inserted into the insert groove, the second connecting part 221 slides relative to the inner wall of the receiving cavity 13, resulting in less friction, which facilitates the movement of the resonator 20 and does not damage the structure of the second connecting part 221 and the rim 10.

[0044] In this embodiment, the resonator 20 may further include an elastic element 23 (e.g., a spring, a rubber pad, etc.), which is connected between the insert 22 and the inner wall of the receiving groove 211, so that the insert 22 can be movably installed in the receiving groove 211. In other embodiments, the end of the insert 22 away from the second connecting portion 221 has an elastic deformation capability, such as a curved or spiral structure, or includes an elastic material structure, such as rubber or silicone. In other embodiments, the resonator 20 may include a noise reduction body 21 and a second connecting portion 221, which is a structure connected to the surface of the noise reduction body 21. The second connecting portion 221 includes an elastic structure, such as a flexible structure like a rubber bump or a silicone bump. The second connecting portion 221 can deform to avoid the rim 10. The second connecting portion 221 can be inserted into the insert groove and moved out of the insert groove under the action of external force. In such embodiments, the structure of the resonator 20 is relatively simple.

[0045] Please see Figure 8 In this embodiment, the insert 22 (and the second connecting portion 221) may include a metal structure or a plastic structure to have high hardness and structural strength, so that the fitting relationship between the second connecting portion 221 and the insert groove is relatively stable. In this embodiment, the second connecting portion 221 has a sliding mating surface 2211 on one side of the rim 10 in the circumferential direction. The sliding mating surface 2211 is inclined relative to the opening of the insert groove, and the sliding mating surfaces 2211 are arranged at intervals along the circumferential direction of the rim 10 on opposite sides in the circumferential direction.

[0046] During the disassembly of the resonator 20, the sliding mating surface 2211 can slide relative to the edge structure of the groove opening, causing the insert 22 to gradually extend into the receiving groove 211, and causing the second connecting portion 221 to gradually disengage from the groove, thereby releasing the mating relationship. In this embodiment, a detachable connection between the first connecting portion 1221 and the second connecting portion 221 is achieved, facilitating the disassembly of the resonator 20, simplifying the operation, and requiring no large force. In other embodiments, the surface of the second connecting portion 221 is curved to allow for sliding mating with the opening of the groove.

[0047] In this embodiment, the axial dimension of the resonator 20 in the rim 10 is approximately the same as the axial dimension of the receiving cavity 13 in the rim 10. This ensures that the inner walls of the receiving cavity 13 on both sides of the rim 10 in the axial direction are respectively attached to the opposite sides of the resonator 20, preventing the resonator 20 from wobbling in the rim 10, avoiding collisions between the resonator 20 and the inner walls of the receiving cavity 13, preventing structural damage to the resonator 20 and the rim 10, and preventing noise generation. In this embodiment, the radial dimension of the resonator 20 in the rim 10 is also approximately the same as the radial dimension of the receiving cavity 13 in the rim 10. This ensures that the inner walls of the receiving cavity 13 on both sides of the rim 10 in the radial direction are respectively attached to the opposite sides of the resonator 20, preventing the resonator 20 from wobbling in the rim 10, avoiding collisions between the resonator 20 and the inner walls of the receiving cavity 13, preventing structural damage to the resonator 20 and the rim 10, and preventing noise generation.

[0048] Please see Figure 2 In this embodiment, the resonator 20 is larger in the circumferential direction of the rim 10 than the receiving cavity 13. With the resonator 20 inserted into the receiving cavity 13, at least one end of the resonator 20 extends out of the receiving cavity 13, allowing for easy installation without the need for tools. In other embodiments, the resonator 20 is equal in size to the receiving cavity 13, and both ends of the resonator 20 are flush with the two ports of the receiving cavity 13. This also allows for easy installation without the need for tools, and the resonator 20 is essentially located inside the receiving cavity 13, preventing damage to the resonator 20 when the tire 30 is deflated. In some other embodiments, the size of the resonator 20 in the circumferential direction of the rim 10 is smaller than the size of the receiving cavity 13 in the circumferential direction of the rim 10. Both ends of the resonator 20 are located in the receiving cavity 13. The structure of the resonator 20 is basically located inside the receiving cavity 13, which can prevent the resonator 20 from being crushed when the tire 30 is deflated.

[0049] In some other embodiments, the first connecting portion 1221 may be a protrusion structure that extends and retracts relative to the inner wall of the receiving cavity 13, and the second connecting portion 221 may be a groove structure formed in the resonator 20. The first connecting portion 1221 and the second connecting portion 221 are detachably fitted together. The cooperation process between the first connecting portion 1221 and the second connecting portion 221 can be referred to the above description, and will not be repeated in this embodiment. In other embodiments, the first connecting portion 1221 and the second connecting portion 221 may have other forms of detachable connection. For example, the first connecting portion 1221 may be a hole or groove formed in the inner wall of the receiving cavity 13, and the second connecting portion 221 may be a hole or groove formed in the resonator 20. External fasteners (screws, pins) are sequentially inserted through the first connecting portion 1221 and the second connecting portion 221 to achieve a detachable connection between the resonator 20 and the rim 10. The connection relationship achieved by the fasteners is relatively stable and can limit the movement of the resonator 20.

[0050] In this embodiment, the number of limiting parts 12 can be multiple, such as two, three, four or more. Multiple limiting parts 12 are arranged sequentially and spaced apart along the circumference of the mounting body 11 to define multiple receiving cavities 13. The wheel assembly 100 in this embodiment includes multiple resonators 20, and the multiple resonators 20 correspond one-to-one with the multiple receiving cavities 13. Each resonator 20 is installed in the corresponding receiving cavity 13, and the multiple resonators 20 can effectively eliminate noise.

[0051] In this embodiment, multiple limiting portions 12 are evenly spaced along the circumference of the mounting body 11, so that multiple resonators 20 are evenly spaced along the circumference of the mounting body 11, thereby ensuring stable rotation of the wheel assembly 100. As another example, there are two limiting portions 12, spaced 180° apart circumferentially on the rim 10, resulting in two receiving cavities 13 being spaced 180° apart circumferentially on the rim 10, and two resonators 20 being spaced 180° apart circumferentially on the rim 10. As another example, there are three limiting portions 12, spaced 120° apart circumferentially on the rim 10, resulting in three receiving cavities 13 being spaced 120° apart circumferentially on the rim 10, and three resonators 20 being spaced 120° apart circumferentially on the rim 10. As another example, there are four limiting parts 12, which are spaced 90° apart in the circumferential direction of the rim 10, so that the four receiving cavities 13 are spaced 90° apart in the circumferential direction of the rim 10, and the four resonators 20 are spaced 90° apart in the circumferential direction of the rim 10.

[0052] In other embodiments, the plurality of limiting parts 12 may be set according to the actual situation of the wheel assembly 100. For example, the number of limiting parts 12 may be two, and the two limiting parts 12 may be spaced 90° (or 270°) apart in the circumferential direction of the rim 10, so that the two receiving cavities 13 may be spaced 90° apart in the circumferential direction of the rim 10, and the two resonators 20 may be spaced 90° apart in the circumferential direction of the rim 10.

[0053] In this embodiment, the mounting body 11 and the limiting part 12 are integrally formed, for example by welding, so that the structure of the rim 10 is more stable, and the limiting effect of the rim 10 on the resonator 20 is more stable.

[0054] In other embodiments, the mounting body 11 and the limiting part 12 are two independent structures that are detachably connected. The structures of the mounting body 11 and the limiting part 12 are relatively simple, with low processing difficulty, fewer production steps, and lower production costs. In such embodiments, the limiting part 12 has a first mounting part (not shown in the figure), and the mounting body 11 has a second mounting part (not shown in the figure). Both second mounting parts can be detachably connected to the first mounting parts. In such embodiments, the number of second mounting parts can be set to be relatively large, with multiple second mounting parts spaced circumferentially along the mounting body 11. The first mounting part on each limiting part 12 can be detachably connected to any one of the second mounting parts. In practical application scenarios, the number of limiting parts 12 can be determined according to the actual noise reduction requirements, which can avoid the limiting parts 12 being idle and increasing the weight of the rim 10, and avoid noise generation in the empty receiving cavity 13.

[0055] In an embodiment where the mounting body 11 and the limiting part 12 are detachably connected, the first mounting part and the second mounting part may include holes or grooves (not limited in number) for fasteners (e.g., screws, pins) to pass through in order to detachably fix the limiting part 12 and the mounting body 11; one of the first mounting part and the second mounting part may include a slot (not limited in number), and the other may be a buckle (not limited in number), and the first mounting part and the second mounting part are fastened together.

[0056] This embodiment does not limit the structure of the limiting part 12. The limiting part 12 can be a plate-like structure or a grid-like structure, as long as it can limit the movement of the resonator 20 with the mounting body 11. In this embodiment, the limiting part 12 has a three-dimensional structure, including an abutment part 121 and a connecting part 122. The abutment part 121 is spaced apart from the opening of the mounting groove 111, and the connecting part 122 connects the abutment part 121 and the mounting body 11. In this embodiment, there are two connecting parts 122, which are respectively connected to the two sides of the abutment part 121 on the axial direction of the rim 10. Each connecting part 122 protrudes relative to the abutment part 121 toward the mounting body 11.

[0057] In this embodiment, the abutment portion 121 and the connecting portion 122 form a clearance groove 123, which communicates with the mounting groove 111. The mounting groove 111, corresponding to a portion of the abutment portion 121, forms a receiving cavity 13 with the clearance groove 123. A portion of the resonator 20 is embedded in the mounting groove 111, and a portion is embedded within the space defined by the limiting portion 12. In this embodiment, the mounting groove 111 has a shallow radial depth in the mounting body 11, resulting in higher structural strength of the mounting body 11. In this embodiment, the first connecting portion 1221 is disposed on the connecting portion 122 and is located on the inner wall of the clearance groove 123. In this embodiment, the structure of the connecting portion 122 has a relatively small impact on the structural strength of the mounting body 11 and the overall structural strength of the rim 10, thus minimizing the impact of the first connecting portion 1221 on the rim structure. In some other embodiments, the first connecting portion 1221 may be disposed on the inner wall of the mounting groove 111 to enhance the stability of the connection between the resonator 20 and the mounting body 11.

[0058] This application provides a wheel assembly 100, which includes a rim 10 and a resonator 20. The resonator 20 is mounted on the rim 10 to reduce noise. In this embodiment, the rim 10 includes a mounting body 11 and a limiting part 12. The mounting body 11 has a mounting groove 111, which surrounds the outer periphery of the mounting body 11. The limiting part 12 is connected to the peripheral structure of the mounting groove 111, and corresponds to and covers a portion of the groove of the mounting groove 111. The mounting groove 111 and the limiting part 12 form a receiving cavity 13, and the resonator 20 is mounted in the receiving cavity 13.

[0059] In this embodiment, the resonator 20 passes through the receiving cavity 13, so that the structure of the rim 10 covers the outer periphery of the resonator 20. This restricts the resonator 20 from moving significantly in the axial and radial directions of the rim 10, making the position of the resonator 20 on the rim 10 more stable, thus achieving stable mounting of the resonator 20 on the rim 10. In practical applications, when the wheel assembly 100 rotates rapidly, the resonator 20 is subjected to centrifugal force, and the limiting part 12 can effectively restrict the radial movement of the resonator 20 on the rim 10. When the tire 30 is deflated, the limiting part 12 is located between the tire 30 and the resonator 20. The limiting part 12 can protect the resonator 20 from being crushed and also prevent fragments of the resonator 20 from damaging the rim 10 and the tire 30.
