Description

[0001] The invention relates to a vehicle wheel arrangement.

[0002] Vehicle wheels are a source of noise, vibration, and harshness (NVH). Their contribution to exterior and interior noise is further amplified in electrified vehicles. A significant portion of the generated NVH can be attributed to so-called tire cavity noise, which occurs when the air torus within the tire is excited by ingress from the road surface. On the one hand, this leads to stronger radiated (pass-by) noise emanating directly from the tire. On the other hand, these cavity vibrations are transmitted through the wheel to the wheel hub and further, via several transmission paths, to noise and vibrations in the passenger compartment. Tire cavity vibrations can manifest as a droning noise in the passenger compartment.

[0003] Known solutions utilize the principle of the Helmholtz resonator, in which an air plug in an opening oscillates on a resilient air cushion or within the volume of a housing. However, these housings have complex geometries and enclose the relevant volume themselves, making them complex and expensive to manufacture, as well as undesirably heavy. Furthermore, Helmholtz resonators are known to be attached to fasteners formed by the rim itself, such as flanges or rims. These fasteners, however, require the rim geometry to be adapted to a single suitable resonator. The rim design itself is therefore also complex, resulting in a rim with a complex geometry that is costly to manufacture.

[0004] The object of the invention is therefore to improve the state of the art, in particular to create a means for reducing tire cavity vibrations that has a low-complexity geometry, is cost-effective and also has a low weight.

[0005] This problem is solved by the vehicle wheel arrangement according to a first aspect with the features of claim 1, by the vehicle wheel arrangement according to a second aspect with the features of claim 14 and by the vehicle wheel arrangement according to a third aspect with the features of claim 15.

[0006] It was recognized that tire cavity noise can be avoided even if the resonator alone cannot form a functioning Helmholtz volume, but only if it is arranged on the rim. Only through the inventive arrangement of the shell on the rim is a functioning Helmholtz volume defined by the shell and the rim. This allows for greater design freedom in the resonator. According to the invention, a shell is proposed that is attached to the rim. The shell is therefore bottomless, resulting in a reduction in manufacturing and assembly costs, a reduction in weight, and less complexity. Thus, the arrangements based on these three aspects share the only general inventive concept.

[0007] According to the first aspect of the invention, a vehicle wheel arrangement is disclosed comprising a wheel comprising a rim, at least one shell fastening device attached to the rim by a material-fit connection, and a shell arranged on the rim by the shell fastening device, which provides a fastening connection therefor, wherein the rim and the shell together define a Helmholtz volume.

[0008] According to the first aspect of the invention, the rim shell is not attached to a specifically provided rim geometry, but rather to a separate rim mounting device. The rim mounting device is a separate component from both the rim and the rim shell. It can also be referred to as a docking station. The at least one rim mounting device is attached to the outer surface or circumferential surface of the rim. The rim shell is positioned on the outer surface of the rim. The rim mounting device thus forms a connection with the rim for its attachment to it and another connection with the rim for securing the rim shell. The rim mounting device, or a portion thereof, is attached to the rim by means of a material-fit connection. This connection secures the rim shell to the rim.The shell mounting device and / or the fastening connection secures the shell in a stationary and immovable position relative to the rim. This ensures consistently good performance. The rim can be made of a metal, for example, aluminum and / or steel.

[0009] The solution can be applied to suitable existing rim designs, as the rim profile does not need to be modified. The Helmholtz volume is a secondary cavity within a tire cavity. The Helmholtz volume created by the rim shell and the rim has a connecting opening. Through this connecting opening, the Helmholtz volume can be open to a tire cavity. The connecting opening can be delimited by the rim shell and / or the rim. The connecting opening can be located on a transverse side of the rim shell that runs in the axial direction. This creates an interaction between the Helmholtz volume and the tire cavity. The vehicle wheel assembly can include a tire mounted on the rim, with the tire and rim together defining a tire cavity.

[0010] According to an optional embodiment of the invention as described in the first aspect, the rim comprises a cylindrical or conical outer circumferential surface to which the shell mounting device is attached. This advantageously confirms that no modification of the rim side is required to position the shell there, since this is not dependent on fastening elements formed by the rim itself.

[0011] According to an optional embodiment of the invention as described in the first aspect, the shell can be a half-shell and / or open towards the rim and / or bottomless. The shell need not have an undercut in the radial direction. This makes it simple, inexpensive, and easy to manufacture with simple tools. The shell can be made in one piece, preferably from a single material. This also allows its manufacture to be simple and inexpensive.

[0012] According to an optional embodiment of the invention as described in the first aspect, the material bond is achieved by gluing, welding, or brazing. Each of these methods represents a cost-effective and durable way of attaching the component to the rim. The material bond can be made in direct contact with the outer surface of the rim. The welded material bond can be a spot weld.

[0013] According to an optional embodiment of the invention as described in the first aspect, the material-bonded connection extends at most 0.5 mm into the rim material. This depth is sufficient to create a durable bond, yet shallow enough to avoid heat damage and aesthetic problems on the rim. Furthermore, this depth prevents any negative impact on the durability of the rim itself.

[0014] According to an optional embodiment of the invention as described in the first aspect, the fastening connection is achieved by a positive-locking connection and / or a force-locking connection, preferably by notching, clipping, screwing, riveting and / or crimping, or by gluing, welding, or soldering. Each of these variants represents a cost-effective and durable method of fastening to the rim mounting device. Furthermore, each of these variants allows the rim to be replaced if necessary and prevents the rim from detaching from the rim during vehicle use. Each of these variants is also suitable for pressing the rim onto the rim or securing a molded-in contact pressure. This serves to seal the Helmholtz volume.

[0015] In notching, the notch can initially be created when the shell is attached. The notch can be created or positioned in the shell mounting device, or it can be created in the shell itself. The shell mounting device or the shell can incorporate a notch. The notch is a cutting notch. This variant is very cost-effective because no special geometric requirements need to be placed on the parts to be joined. One part creates its own notches in the other part.

[0016] When using a clip-on system, the rim mounting device can include a clip that is itself connected to the rim via a material-bonded connection and is then clipped to the rim shell. The rim mounting device can include clip partners. Clipping can be done in a flash and permanently positions the rim shell in a desired position. The clip connection can also be a reversible and / or damage-free reversible connection. This makes replacing the rim shell easy.

[0017] When using screws, the shell fastening device can comprise two screw partners with corresponding threads. Screw connections are easy to loosen and re-engage, thus simplifying maintenance and repair work. Screwing is generally cost-effective and does not require special tools or complex processes. The screw connection can be a self-locking screw connection; for example, the shell fastening device can include a preload device that applies a preload force to the shell fastening device or the fastening connection, preferably in a radial direction. Self-locking prevents loosening.

[0018] When riveting, the shell fastening device can consist of a rivet, a blind rivet, or a blind rivet nut. The rivet can thus form the material-fit connection with the rim for its attachment to the rim and can also be used to attach the shell to the rim. The fastening connection can be created by plastic deformation of the rivet and / or by screwing a bolt into the blind rivet nut.

[0019] In crimping, the rim mounting device can include a crimping element. The crimping element can thus form the material-bonded connection with the rim for its attachment to the rim and can also be used to attach the rim shell to the rim shell. The fastening connection can be created by plastic deformation of the crimping element.

[0020] When bonding, the shell fastening device can include an adhesive or bonding agent. The adhesive / bonding agent bonds to the shell fastening device and the shell.

[0021] According to an optional embodiment of the invention according to the first aspect, the shell is pressed against the rim by the fastening connection and / or the shell fastening device.

[0022] The fastening connection and / or the shell fastening device are configured to apply a force directed towards the rim in a radial direction to the shell. This ensures secure fixation, prevents rattling, and seals the Helmholtz volume. It is conceivable that a preload gap exists between the shell and the shell fastening device, or a part of the shell fastening device, when this force is not present. This preload gap closes when the fastening connection is made and the preload force is applied. It is also conceivable that the shell deforms elastically due to the force.

[0023] According to an optional embodiment of the invention as described in the first aspect, the rim mounting device comprises a first mounting partner, which is attached to the rim by means of a material-fit connection, and a second mounting partner. The rim mounting device can thus consist of (at least) two parts. The two partners are separate from each other. The first mounting partner is attached to the rim, preferably directly. The second mounting partner can be attached to the rim, preferably before the mounting connection is created. The second mounting partner can be formed integrally with the rim. The second mounting partner can be formed by the rim; preferably, the second mounting partner can be a hole or a recess in the rim into or through which the first mounting partner engages.The two fastening components can be attached to each other, preferably creating the fastening connection. Together, the two fastening components serve to fasten the shell cost-effectively and with low complexity.

[0024] The first or second fastening partner can form a support surface for the shell. The shell can rest against this support surface, ensuring a secure final position. The shell can be pressed against the support surface by the shell fastening device and / or the fastening connection.

[0025] A third fastening partner is also conceivable, preferably in the case of a first and a second fastening partner. The first, second, and third fastening partners can act together as fastening means for the shell. The third fastening partner can be formed by the shell; preferably, the third fastening partner can be a hole or a recess in the shell into or through which at least one of the other two fastening partners engages, preferably both. Preferably, if the third fastening partner is a hole or a recess in the shell, the second fastening partner need not be a hole or a recess in the shell.

[0026] According to an optional embodiment of the invention according to the first aspect, in the case of a fastening connection by clips, the two fastening partners (preferably a first and a second) are clip partners that can be clipped together, preferably the first and the second fastening partner. In principle, clipping requires an undercut on one of the fastening partners and a part that is clipped behind the undercut on the other partner. The clip partners can be formed by a plug-in and a receiving part of a snap rivet. The clip partners can be formed by a plug-in and a receiving part of a snap rivet that includes a locking pin. The clip partners can be formed by a snap hook or arrow-shaped pin and a hole or an undercut. The clip partners can be formed by one or more elastic snap tongues and a hole or an undercut.Each of these variants is quick and easy to attach and secures the shell to the rim.

[0027] According to an optional embodiment of the invention as described in the first aspect, in the case of a fastening connection by screws, the two fastening partners (preferably a first and a second) are screw partners that can be screwed together, preferably by screwing the first and the second fastening partner together. The two partners can each comprise a corresponding thread. The first fastening partner can be a threaded bolt and / or the second fastening partner can be a threaded nut, or vice versa. The first fastening partner can be a threaded bushing and / or the second fastening partner can be a threaded screw, or vice versa.

[0028] The shell fastening device can also include a preloading device. The preloading device generates a preload to secure the bolted connection; preferably, the force acts in a radial direction. It also serves to maintain the bolted connection when the respective components are relaxed. The preloading device can either be elastic itself, for example, made of rubber, and / or generate the preload force through its geometric design. The preloading device also prevents damage to the shell when tightening the bolted connection, as it increases the tolerance against overtightening. This is particularly relevant for a shell made of a plastic material.

[0029] According to an optional embodiment of the invention as described in the first aspect, in the case of a fastening connection by rivets, the two fastening partners (preferably a first and a second) can be riveted together. The first fastening partner can be a rivet, and the second fastening partner can be a hole or a recess in the shell. The rivet can be attached to the rim by means of a material-fit connection. The rivet can be a rivet stud, a rivet sleeve, a blind rivet, or a blind rivet nut. The rivet sleeve, the blind rivet, and the blind rivet nut can be plastically deformable at their free end. The plastic deformation and / or the tightening of a screw with the blind rivet nut results in a positive-locking connection that creates the fastening connection.

[0030] According to an optional embodiment of the invention as described in the first aspect, in a crimping connection, the two fastening partners (preferably a first and a second) can be crimped together. The first fastening partner can be a crimp sleeve, and the second fastening partner can be a hole or a recess in the rim. The crimp sleeve can be attached to the rim by means of a material-fit connection. The crimp sleeve can be plastically deformable at its free end. The plastic deformation results in a positive-locking connection that creates the fastening connection.

[0031] According to an optional embodiment of the invention as described in the first aspect, the first fastening partner is a pin and / or the second fastening partner is a snap-on retainer, or vice versa. The pin is easy to attach. It can extend in a radial direction. The other fastening partner can then also be attached to the pin in the radial direction. The pin can have an undercut, but it can also be without one. The pin can have a cylindrical shape, preferably at least in the attachment area for the second partner. The second partner can be a snap-on retainer. The disc can comprise a ring from which clamping tongues project radially inwards. The tongues are preferably elastic. These clamping tongues can press into the first partner with their free ends and form notches there. An undercut on the pin is therefore not necessary.The pin can be made of a softer material than the locking washer, thus facilitating the formation of notches. The locking washer can be made of a metal, preferably spring steel, to facilitate notch formation. This also prevents material relaxation, thereby preventing unintentional loosening of the fastening connection. The clamping tongues can extend in the opposite direction to the insertion direction once the fastening connection is established. This further secures the fastening connection. The advantages include low cost and minimal installation effort, while simultaneously allowing for low insertion force and very high resistance to loosening.

[0032] According to an optional embodiment of the invention as described in the first aspect, the second fastening partner can be a separate part from the shell and / or permanently attached to the shell or formed integrally with the shell. Each of these three variants has its own advantages. The first and second alternatives allow the second fastening partner to be produced independently of the shell production. This reduces manufacturing costs, particularly when the parts are made of different materials. The second alternative allows the fastening partner to be attached to the shell itself before the fastening connection is created. This simplifies the manufacturing and assembly process. The third alternative eliminates the need for a separate fastening partner with respect to the shell, since the shell itself forms the fastening partner. The fastening partner can therefore be formed simultaneously with the shell production.This reduces the number of process steps required during assembly. The shell and the second fastening partner can be made from a single material. This also allows for simple and cost-effective manufacturing.

[0033] According to an optional embodiment of the invention as described in the first aspect, more than one shell fastening device is assigned to each shell; preferably, exactly two fastening devices are assigned to each shell. It has been shown that two fastening devices are sufficient to securely fasten the shell without negatively affecting its functionality. The shell fastening devices can be spaced apart from each other in the circumferential and / or axial direction.

[0034] According to an optional embodiment of the invention as described in the first aspect, the vehicle wheel assembly comprises more than one shell. Multiple shells can form a corresponding number of Helmholtz volumes, thus improving the effect. Preferably, the vehicle wheel assembly comprises exactly two shells. The two shells can be arranged diametrically opposite to the rim's axis of rotation. This improves the effect and prevents imbalance. Each shell can include a corresponding number of shell fastening devices, which can also be one. Each shell can have its own fastening device(s) that fastens only the corresponding shell. This means that each shell can be attached to and / or distributed on the rim independently of other shells.

[0035] According to an optional embodiment of the invention according to the first aspect, the wheel assembly or the rim has a valve or a valve hole, wherein the shell is arranged such that the connecting opening points away from the valve or a valve hole in the circumferential direction of the rim. If the wheel assembly comprises multiple shells, all connecting openings can point away from the valve or a valve hole. This orientation of the connecting opening(s) prevents the ingress of any fluid(s) into the Helmholtz volume(s) that could enter the tire cavity through the valve. Such a fluid could be a self-sealing fluid for sealing an unwanted puncture in the tire through which air is escaping. Such fluids are conventional aids for repairing punctures in tires.

[0036] According to an optional embodiment of the invention as described in the first aspect, the shell fastening device, or at least one, is arranged on the outer edge(s) or sides of the shell, or within the outer circumference of the shell. The outer circumference is defined in the radial direction. The first alternative is advantageous because the shell fastening device(s) is / are then arranged close to the outer edge(s), which is beneficial for sealing. Less force is required. Furthermore, this arrangement allows the shell fastening device to simultaneously secure the shell and seal the Helmholtz volume. The second alternative is advantageous because it saves installation space, as no fastening means needs to be provided outside the shell or on its outer edges. Preferably, the shell fastening device is surrounded by the Helmholtz volume, preferably at its respective outer circumference.If more than one shell fastening device is assigned to the shell, all shell fastening devices can be surrounded by the Helmholtz volume, preferably at their respective outer circumferences. The shell fastening device(s) can be arranged at a distance from the outer edge(s) or longitudinal sides of the shell extending in the circumferential direction, and / or from the outer edge(s) or transverse sides of the shell extending in the axial direction.

[0037] According to an optional embodiment of the invention according to the first aspect, when viewed in the radial direction, if there are exactly two shell fastening devices, they have a linear arrangement extending in the circumferential direction; if there are exactly three shell fastening devices, they have a triangular arrangement; if there are exactly four devices, they have a quadrilateral arrangement.

[0038] According to an optional embodiment of the invention as described in the first aspect, the shell is airtightly attached to the rim and / or the shell mounting device, preferably by at least one sealing device. The adjacent areas of the shell on the one hand and the rim and / or the shell mounting device on the other hand are airtight. It is understood that the Helmholtz volume is not completely closed, but has a neck through which the Helmholtz volume is connected to the shell's surroundings. The surroundings can be a tire cavity if a tire is mounted on the rim. Preferably, the shell is completely sealed against its surroundings, with the exception of the connecting opening. It is conceivable that the shell rests directly against the rim and / or the shell mounting device in an airtight manner without a specifically provided sealing means.It is conceivable that the shell fastening device and / or the fastening connection are designed such that the force applied to the shell in the radial direction is sufficient to ensure an adequate seal. The at least one sealing device can be an elastic seal (for example, a rubber gasket), adhesive tape, or a strip of tape. However, the at least one sealing device can also be an adhesive seam, a weld seam, or a brazed seam. The at least one sealing device can be added to / attached to either the shell or the rim, or both.

[0039] According to an optional embodiment of the invention as described in the first aspect, the sealing device comprises an outer sealing device arranged on an outer circumference of the Helmholtz volume, and / or at least one inner sealing device arranged on an inner circumference of the Helmholtz volume. Both sealing devices seal the Helmholtz volume against the shell environment. The inner sealing device(s) creates a region within the outer circumference of the shell that is sealed against the Helmholtz volume. A shell fastening device can advantageously be arranged in this region. This is particularly advantageous if the shell has a fastening hole in which the shell fastening device is arranged. Preferably, each shell fastening device is sealed by a single inner sealing device.Preferably, the shell has only a single external sealing device, preferably one-piece.

[0040] According to an optional embodiment of the invention as described in the first aspect, the shell includes a mounting hole for the shell mounting device. Preferably, the mounting hole is surrounded on its outer circumference by the Helmholtz volume or is arranged adjacent to the Helmholtz volume. The mounting hole preferably extends in a radial direction. Preferably, each shell mounting device is arranged in a mounting hole; more preferably, each shell mounting device has its own mounting hole. The mounting hole can be a through hole. It can extend from the outer circumference of the shell to the outer circumference of the rim. This facilitates easy attachment to the shell mounting device. The wall of the mounting hole can extend in a radial direction; it can surround the shell mounting device.It is conceivable that the wall forms a groove to accommodate a sealing device, preferably at its free end. This simplifies the geometry and achieves a good seal. The groove can be an annular groove and / or located at the end of the wall.

[0041] According to an optional embodiment of the invention as described in the first aspect, the shell itself has no holes. The shell can, at least for its attachment, have no holes. This makes its production very easy and inexpensive.

[0042] According to an optional embodiment of the invention as described in the first aspect, the shell can delimit only a single Helmholtz volume. This also makes the geometry less complex and reduces manufacturing and assembly costs.

[0043] According to an optional embodiment of the invention according to the first aspect, the shell comprises at least one flange, preferably two flanges on each of its transverse sides, wherein the shell fastening device is attached to the flange(s). The shell can thus be longer in the circumferential direction, and the fastenings do not occupy any space within the Helmholtz volume.

[0044] According to an optional embodiment of the invention as described in the first aspect, the shell forms a Helmholtz neck, preferably the rim and the shell together define the neck. The neck of the shell can be designed as a groove. The groove can be bottomless, i.e., open towards the rim. This results in a very simple geometry that can be produced cost-effectively. The connecting opening can be positioned at the end of the neck that points away from the Helmholtz volume. At the other end, the neck is open towards the Helmholtz volume. The connecting opening and / or the neck can be arranged on a transverse side of the shell, with the transverse side running in the axial direction.

[0045] According to an optional embodiment of the invention as described in the first aspect, the Helmholtz volume can be arranged laterally adjacent to the neck, preferably on both longitudinal sides of the neck. The Helmholtz volume can extend along the neck at least on one side of the neck, preferably on both sides of the neck. This saves installation space, since the neck does not protrude freely from the shell, but is compactly recessed slightly into the shell. It is conceivable that the shell separates the neck from the Helmholtz volume in its longitudinal direction by means of a groove(s) and / or a wall(s), which it preferably forms itself. The groove(s) or the wall(s) can run parallel to the neck. This increases the Helmholtz volume by those areas on the side of the neck.

[0046] According to an optional embodiment of the invention as described in the first aspect, it is conceivable that the groove(s) and / or the wall(s) between the Helmholtz volume and the neck are sealed, preferably by a sealing device, more preferably by the external sealing device. This means that even with this design, a single external sealing means may be sufficient. This seal separates the longitudinal sides of the neck from the Helmholtz volume.

[0047] According to an optional embodiment of the invention as described in the first aspect, the shell is a plastic part or a metal part and / or is an injection-molded part or a thermoformed part. Both plastic (e.g., thermoplastic or thermosetting plastic) and metal (e.g., aluminum) are suitable for cost-effective and time-efficient injection molding and thermoforming of the inventive shell. A plastic shell is easy to manufacture because it has no base. Thus, no complex processes, such as blow molding, are required for its production. A metal shell is particularly suitable for welding. The metal shell can be a sheet metal shell. Furthermore, a metal shell is more resistant to forces, so that, for example, forces occurring during the attachment of the shell can be accommodated with higher tolerances. A metal shell is robust and does not break or become loose under tire pressure.

[0048] According to the invention, a set is proposed comprising a shell fastening device and a shell, each as disclosed. The disclosed features of the shell, the connections, and the shell fastening device are also disclosed as suitable for corresponding interaction with the rim.

[0049] According to the second aspect of the invention, a vehicle wheel arrangement is disclosed comprising a wheel comprising a rim, a shell which is attached directly to the rim by a material-bonded connection, wherein the rim and the shell together define a Helmholtz volume.

[0050] According to the second aspect of the invention, the shell is not attached to a specifically designed rim geometry, but rather directly to the rim using a bonded connection. The shell is positioned on the outer surface of the rim. The bonded connection secures the shell to the rim, ensuring it is stationary and immovable relative to the rim. This guarantees consistently good performance. Direct attachment of the shell is very cost-effective and can be achieved without additional fastening components. It has also been shown that a bonded connection can be created cost-effectively. This bonded connection joins the rim material to the shell material. The rim can be made of a metal, for example, aluminum and / or steel.

[0051] The solution can be applied to suitable existing rim designs, as the rim profile does not need to be modified. The Helmholtz volume is a secondary cavity within a tire cavity. The Helmholtz volume created by the rim shell and the rim has a connecting opening. Through this connecting opening, the Helmholtz volume can be open to a tire cavity. The connecting opening can be delimited by the rim shell and / or the rim. The connecting opening can be located on a transverse side of the rim shell that runs in the axial direction. This creates an interaction between the Helmholtz volume and the tire cavity. The vehicle wheel assembly can include a tire mounted on the rim, with the tire and rim together defining a tire cavity.

[0052] According to an optional embodiment of the invention as described in the second aspect, the rim comprises a cylindrical or conical outer circumferential surface to which the shell is attached. This advantageously confirms that no modification of the rim side is required to position the shell there, since this is not dependent on fastening elements formed by the rim itself.

[0053] According to an optional embodiment of the invention as described in the second aspect, the shell can be a half-shell and / or open towards the rim and / or bottomless. The shell need not have an undercut in the radial direction. This makes it simple, inexpensive, and easy to manufacture with simple tools. The shell can be made in one piece, preferably from a single material. This also allows its manufacture to be simple and inexpensive.

[0054] According to an optional embodiment of the invention as described in the second aspect, the material bond is achieved by gluing, welding, or brazing. Each of these methods represents a cost-effective and durable way of attaching the component to the rim. The material bond can be made in direct contact with the outer surface of the rim. The welded material bond can be a spot weld.

[0055] According to an optional embodiment of the invention as described in the second aspect, the material-bonded connection extends at most 0.5 mm into the rim material. This depth is sufficient to create a durable bond, yet shallow enough to avoid heat damage and aesthetic problems on the rim. Furthermore, this depth prevents any negative impact on the durability of the rim itself.

[0056] According to an optional embodiment of the invention as described in the second aspect, the bonded connection presses the shell against the rim or maintains a preload that has been applied to the shell. This preload may have been applied during the creation of the bonded connection. The bonded connection is thus configured to apply or maintain a force directed towards the rim in a radial direction against the shell. This ensures secure fixation, prevents rattling, and seals the Helmholtz volume. It is conceivable that the shell deforms elastically due to this force.

[0057] According to an optional embodiment of the invention as described in the second aspect, it is conceivable that the material-bonded connection is constructed as an elongated seam and / or as dots. The seam is used to create a tighter seal, while the dot construction further reduces costs.

[0058] According to an optional embodiment of the invention as described in the second aspect, the vehicle wheel assembly comprises more than one shell. Multiple shells allow for the formation of a corresponding number of Helmholtz volumes, thus improving the effect. Preferably, the vehicle wheel assembly comprises exactly two shells. The two shells can be arranged diametrically opposite to the rim's axis of rotation. This improves the effect and prevents imbalance.

[0059] According to an optional embodiment of the invention according to the second aspect, the wheel assembly or the rim has a valve or a valve hole, wherein the shell is arranged such that the connecting opening points away from the valve or a valve hole in the circumferential direction of the rim. If the wheel assembly comprises multiple shells, all connecting openings can point away from the valve or a valve hole. This orientation of the connecting opening(s) prevents the ingress of any fluid(s) into the Helmholtz volume(s) that could enter the tire cavity through the valve. Such a fluid could be self-sealing fluid for sealing an unwanted puncture in the tire through which air is escaping. Such fluids are conventional aids for repairing punctures in tires.

[0060] According to an optional embodiment of the invention as described in the second aspect, the material-bonded connection is arranged at the outer edge(s) or sides of the shell, or within the outer circumference of the shell. The outer circumference is defined in the radial direction. The first alternative is advantageous because the material-bonded connection is then located close to the outer edge(s), which is beneficial for sealing. Less force is required. Furthermore, this arrangement can result in the material-bonded connection simultaneously securing the shell and sealing the Helmholtz volume. The second alternative is advantageous because it saves installation space, as no fastening means needs to be provided outside the shell or at its outer edges. Preferably, the material-bonded connection is surrounded by the Helmholtz volume, preferably at its respective outer circumference.The material-bonded connection can be arranged at a distance from the outer edge(s) or longitudinal sides of the shell that run in the circumferential direction, and / or from the outer edge(s) or transverse sides of the shell that run in the axial direction.

[0061] According to an optional embodiment of the invention as described in the second aspect, the shell is airtightly attached to the rim and / or the shell mounting device, preferably by at least one sealing device or by a material-bonded connection. The adjacent areas of the shell on the one hand and the rim on the other are airtight. It is understood that the Helmholtz volume is not completely closed, but has a neck through which the Helmholtz volume is connected to the shell's surroundings.

The at least one sealing device can be an elastic seal (for example, a rubber gasket), an adhesive tape, or a strip of tape. However, the at least one sealing device can also be an adhesive seam, a weld seam, or a soldered seam. The at least one sealing device can be added to / attached to either the shell or the rim, or both.

[0062] According to an optional embodiment of the invention as described in the second aspect, the sealing device comprises an outer sealing device arranged on an outer circumference of the Helmholtz volume. The sealing device seals the Helmholtz volume against the shell environment. Preferably, the shell has only a single outer sealing device, preferably a single piece.

[0063] According to an optional embodiment of the invention as described in the second aspect, the shell itself has no holes. This makes its production very easy and inexpensive.

[0064] According to an optional embodiment of the invention as described in the second aspect, the shell can delimit only a single Helmholtz volume. This also makes the geometry less complex and reduces manufacturing and assembly costs.

[0065] According to an optional embodiment of the invention as described in the second aspect, the shell comprises at least one flange, preferably two flanges on each of its transverse sides, with the shell fastening device being attached to the flange(s). The shell can thus be longer in the circumferential direction, and the fastenings do not occupy any space within the Helmholtz volume.

[0066] According to an optional embodiment of the invention as described in the second aspect, the shell forms a Helmholtz neck, preferably with the rim and the shell together defining the neck. The neck of the shell can be designed as a groove. The groove can be bottomless, i.e., open towards the rim. This results in a very simple geometry that can be produced cost-effectively. The connecting opening can be positioned at the end of the neck that points away from the Helmholtz volume. At the other end, the neck is open towards the Helmholtz volume. The connecting opening and / or the neck can be arranged on a transverse side of the shell, with the transverse side running in the axial direction.

[0067] According to an optional embodiment of the invention as described in the second aspect, the Helmholtz volume can be arranged laterally adjacent to the neck, preferably on both longitudinal sides of the neck. The Helmholtz volume can extend along the neck at least on one side of the neck, preferably on both sides. This saves installation space, since the neck does not protrude freely from the shell, but is compactly recessed slightly into the shell. It is conceivable that the shell separates the neck from the Helmholtz volume in its longitudinal direction by means of a groove(s) and / or a wall(s), which it preferably forms itself. The groove(s) or the wall(s) can run parallel to the neck. This increases the Helmholtz volume by those areas on the side of the neck.

[0068] According to an optional embodiment of the invention as described in the second aspect, it is conceivable that the groove(s) and / or the wall(s) between the Helmholtz volume and the neck are sealed, preferably by a sealing device, more preferably by the external sealing device. This means that even with this design, a single external sealing means may be sufficient. This seal separates the longitudinal sides of the neck from the Helmholtz volume.

[0069] According to an optional embodiment of the invention as described in the second aspect, the shell is a plastic part or a metal part and / or is an injection-molded part or a deep-drawn part. Both plastic (e.g., thermoplastic or thermoset plastic) and metal (e.g., aluminum) are suitable for cost-effective and time-efficient injection molding and deep drawing of the inventive shell. A plastic shell is easy to manufacture because it has no base. Thus, no complex processes, such as blow molding, are required for its production. A metal shell is particularly suitable for welding. The metal shell can be a sheet metal shell. Furthermore, a metal shell is more resistant to forces, so that, for example, forces occurring during the attachment of the shell can be accommodated with higher tolerances. A metal shell is robust and does not break or become loose under tire pressure.

[0070] According to the third aspect of the invention, a vehicle wheel arrangement is disclosed comprising a wheel comprising a rim, at least one shell fastening device attached to the rim or a shell by a frictional connection and / or a positive locking connection, and a shell arranged on the rim by the shell fastening device, wherein the rim and the shell together define a Helmholtz volume, wherein the shell fastening device is fixed in a fixing hole in the rim or in a fixing hole of the shell.

[0071] According to the third aspect of the invention, the rim shell is not attached to a specifically provided rim geometry, but rather to a separate rim mounting device. The rim mounting device is a separate component from both the rim and the rim shell. It can also be referred to as a docking station. The at least one rim mounting device is fixed in a fixing hole in the rim, the hole being located on the outer circumference of the rim shell. The rim shell is positioned on the outer surface of the rim. The rim mounting device thus forms a connection with the rim for its attachment to it and another connection with the rim shell for securing the rim shell. The rim mounting device, or a portion thereof, is attached to the rim by means of a frictional and / or positive locking connection. This connection secures the rim shell to the rim.The shell mounting device and / or the fastening connection secures the shell in a stationary and immovable position relative to the rim. This ensures consistently good performance. The rim can be made of a metal, for example, aluminum and / or steel.

[0072] The solution can be applied to suitable existing rim designs, as the rim profile does not need to be modified. The Helmholtz volume is a secondary cavity within a tire cavity. The Helmholtz volume created by the rim shell and the rim has a connecting opening. Through this connecting opening, the Helmholtz volume can be open to a tire cavity. The connecting opening can be delimited by the rim shell and / or the rim. The connecting opening can be located on a transverse side of the rim shell that runs in the axial direction. This creates an interaction between the Helmholtz volume and the tire cavity. The vehicle wheel assembly can include a tire mounted on the rim, with the tire and rim together defining a tire cavity.

[0073] According to an optional embodiment of the invention as described in the third aspect, the at least one fixing hole is covered by a spoke of the rim when viewed in the axial direction. This reduces the exposure of the fixing hole and the cup fastening device fixed therein to dirt.

[0074] According to an optional embodiment of the invention according to the third aspect, the at least one fixing hole is a through hole that extends from the inner circumferential surface to the outer circumferential surface of the rim.

[0075] According to an optional embodiment of the invention as described in the third aspect, the fixing hole extends in the radial direction. This simplifies the fastening of the shell fixing device.

[0076] According to an optional embodiment of the invention as described in the third aspect, the rim comprises a cylindrical or conical outer circumferential surface that provides the fixing hole for attaching the shell mounting device. This advantageously confirms that no modification to the rim design is required to position the shell there, since this is not dependent on fastening elements formed by the rim itself.

[0077] According to an optional embodiment of the invention as described in the third aspect, the shell can be a half-shell and / or open towards the rim and / or bottomless. The shell need not have an undercut in the radial direction. This makes it simple, inexpensive, and easy to manufacture with simple tools. The shell can be made in one piece, preferably from a single material. This also allows its manufacture to be simple and inexpensive.

[0078] According to an optional embodiment of the invention as described in the third aspect, there is no material bond when attaching the shell to the rim. Advantageously, only mechanical solutions are provided for attaching the shell to the rim, specifically exclusively force-fit and / or form-fit connections. Each of these variants represents a cost-effective and durable method of attachment to the rim.

[0079] According to an optional embodiment of the invention as described in the third aspect, the fastening connection is achieved by a positive-locking connection and / or a force-locking connection, preferably by notches, clips, screws, rivets, and / or crimping. Each of these variants represents a cost-effective and durable method of fastening to the rim mounting device. Furthermore, each of these variants allows the rim to be replaced if necessary and prevents the rim from detaching from the rim during vehicle use. Each of these variants is also suitable for pressing the rim onto the rim or securing a molded-in contact pressure. This serves to seal the Helmholtz volume.

[0080] In notching, the notch can initially be created when the shell is attached. The notch can be created or positioned in the shell mounting device, or it can be created in the shell itself. The shell mounting device or the shell can incorporate a notch. The notch is a cutting notch. This variant is very cost-effective because no special geometric requirements need to be placed on the parts to be joined. One part creates its own notches in the other part.

[0081] When using a clip-on system, the rim mounting device can include a clip mechanism that is itself connected to the rim via a frictional and / or positive locking connection and is then clipped to the rim shell. The rim mounting device can include clip components. Clipping can be done in a flash and permanently positions the rim shell in a desired position. The clip connection can also be reversible and / or damage-free, making rim shell replacement easy.

[0082] When using screws, the shell fastening device can comprise two screw partners with corresponding threads. Screw connections are easy to loosen and re-engage, thus simplifying maintenance and repair work. Screwing is generally cost-effective and does not require special tools or complex processes. The screw connection can be a self-locking screw connection; for example, the shell fastening device can include a preload device that applies a preload force to the shell fastening device or the fastening connection, preferably in a radial direction. Self-locking prevents loosening.

[0083] When riveting, the shell fastening device can consist of a rivet, a blind rivet, or a blind rivet nut. The rivet can thus form the connection to the rim for its attachment to the rim and can also be used to attach the shell to the rim. The fastening connection can be created by plastic deformation of the rivet and / or by screwing a bolt into the blind rivet nut.

[0084] In crimping, the rim mounting device can include a crimping element. The crimping element can thus form the friction-fit and / or positive-fit connection with the rim for its attachment to the rim and can be used to attach the rim shell to the rim shell. The fastening connection can be created by plastic deformation of the crimping element.

[0085] According to an optional embodiment of the invention as described in the third aspect, the mounting connection and / or the shell mounting device presses the shell against the rim. The mounting connection and / or the shell mounting device are thus configured to apply a force directed towards the rim in a radial direction to the shell. This ensures secure fixation, prevents rattling, and seals the Helmholtz volume. It is conceivable that a preload gap exists between the shell and the shell mounting device, or a part of the shell mounting device, when this force is not present. This preload gap closes when the mounting connection is established and the preload force is applied. It is also conceivable that the shell deforms elastically due to the force.

[0086] According to an optional embodiment of the invention as described in the third aspect, the rim mounting device comprises a first mounting partner, which is attached to the rim by means of a force-fit and / or a form-fit connection, and a second mounting partner. The rim mounting device can thus consist of (at least) two parts. The two partners are separate from each other. The first mounting partner is attached to the rim, preferably directly. The second mounting partner can be attached to the rim, preferably before the mounting connection is created. The second mounting partner can be formed integrally with the rim. The second mounting partner can be formed by the rim; preferably, the second mounting partner can be a hole or a recess in the rim into or through which the first mounting partner engages.The two fastening components can be attached to each other, preferably creating the fastening connection. Together, the two fastening components serve to fasten the shell cost-effectively and with low complexity.

[0087] The first or second fastening partner can form a support surface for the shell. The shell can rest against this support surface, ensuring a secure final position. The shell can be pressed against the support surface by the shell fastening device and / or the fastening connection.

[0088] A third fastening partner is also conceivable, preferably in the case of a first and a second fastening partner. The first, second, and third fastening partners can act together as fastening means for the shell. The third fastening partner can be formed by the shell; preferably, the third fastening partner can be a hole or a recess in the shell into or through which at least one of the other two fastening partners engages, preferably both. Preferably, if the third fastening partner is a hole or a recess in the shell, the second fastening partner need not be a hole or a recess in the shell.

[0089] According to an optional embodiment of the invention as described in the third aspect, in the case of a fastening connection by clips, the two fastening partners (preferably a first and a second) are clip partners that can be clipped together, preferably the first and the second fastening partner. In principle, clipping requires an undercut on one of the fastening partners and a part that is clipped behind the undercut on the other partner. The clip partners can be formed by a plug-in and a receiving part of a snap rivet. The clip partners can be formed by a plug-in and a receiving part of a snap rivet that includes a locking pin. The clip partners can be formed by a snap hook or arrow-shaped pin and a hole or an undercut. The clip partners can be formed by one or more elastic snap tongues and a hole or an undercut.Each of these variants is quick and easy to attach and secures the shell to the rim.

[0090] According to an optional embodiment of the invention as described in the third aspect, in the case of a fastening connection by screws, the two fastening partners (preferably a first and a second) are screw partners that can be screwed together, preferably by screwing the first and the second fastening partner together. The two partners can each comprise a corresponding thread. The first fastening partner can be a threaded bolt and / or the second fastening partner can be a threaded nut, or vice versa. The first fastening partner can be a threaded bushing and / or the second fastening partner can be a threaded screw, or vice versa.

[0091] The shell fastening device can also include a preloading device. The preloading device generates a preload to secure the bolted connection; preferably, the force acts in a radial direction. It also serves to maintain the bolted connection when the respective components are relaxed. The preloading device can either be elastic itself, for example, made of rubber, and / or generate the preload force through its geometric design. The preloading device also prevents damage to the shell when tightening the bolted connection, as it increases the tolerance against overtightening. This is particularly relevant for a shell made of a plastic material.

[0092] According to an optional embodiment of the invention as described in the third aspect, in the case of a fastening connection by rivets, the two fastening partners (preferably a first and a second) can be riveted together. The first fastening partner can be a rivet, and the second fastening partner can be a hole or a recess in the shell. The rivet can be attached to the rim by a frictional connection and / or a positive-locking connection. The rivet can be a rivet stud, a rivet sleeve, a blind rivet, or a blind rivet nut. The rivet sleeve, blind rivet, or blind rivet nut can be plastically deformable at its free end. The plastic deformation and / or the tightening of a screw with the blind rivet nut results in a positive-locking connection that creates the fastening connection.

[0093] According to an optional embodiment of the invention as described in the third aspect, in a crimp connection, the two fastening partners (preferably a first and a second) can be crimped together. The first fastening partner can be a crimp sleeve, and the second fastening partner can be a hole or a recess in the rim. The crimp sleeve can be attached to the rim by frictional and / or positive locking. The crimp sleeve can be plastically deformable at its free end. The plastic deformation results in a positive locking connection, which creates the fastening connection.

[0094] According to an optional embodiment of the invention as described in the third aspect, it is conceivable that the force-fit connection and / or the form-fit connection is identical to the shell fastening connection. Such a construction can be created, for example, using a rivet. The rivet is fixed in the fixing hole by its plastic deformation and simultaneously fastens the shell. This construction is very efficient and cost-effective.

[0095] According to an optional embodiment of the invention as described in the third aspect, the first fastening partner is a pin and / or the second fastening partner is a snap-on retainer, or vice versa. The pin is easy to attach. It can extend in a radial direction. The other fastening partner can then also be attached to the pin in the radial direction. The pin can have an undercut, but it can also be without one. The pin can have a cylindrical shape, preferably at least in the attachment area for the second partner. The second partner can be a snap-on retainer. The disc can comprise a ring from which clamping tongues project radially inwards. The tongues are preferably elastic. These clamping tongues can press into the first partner with their free ends and form notches there. An undercut on the pin is therefore not necessary.The pin can be made of a softer material than the locking washer, thus facilitating the formation of notches. The locking washer can be made of a metal, preferably spring steel, to facilitate notch formation. This also prevents material relaxation, thereby preventing unintentional loosening of the fastening connection. The clamping tongues can extend in the opposite direction to the insertion direction once the fastening connection is established. This further secures the fastening connection. The advantages include low cost and minimal installation effort, while simultaneously allowing for low insertion force and very high resistance to loosening.

[0096] According to an optional embodiment of the invention as described in the third aspect, the second fastening partner can be a separate part from the shell and / or permanently attached to the shell or formed integrally with the shell. Each of these three variants has its own advantages. The first and second alternatives allow the second fastening partner to be produced independently of the shell production. This reduces manufacturing costs, particularly when the parts are made of different materials. The second alternative allows the fastening partner to be attached to the shell itself before the fastening connection is created. This simplifies the manufacturing and assembly process. The third alternative eliminates the need for a separate fastening partner with respect to the shell, since the shell itself forms the fastening partner. The fastening partner can therefore be formed simultaneously with the shell production.This reduces the number of process steps required during assembly. The shell and the second fastening partner can be made from a single material. This also allows for simple and cost-effective manufacturing.

[0097] According to an optional embodiment of the invention as described in the third aspect, more than one shell fastening device is assigned to each shell; preferably, exactly two fastening devices are assigned to each shell. It has been shown that two fastening devices are sufficient to securely fasten the shell without negatively affecting its functionality. The shell fastening devices can be spaced apart from each other in the circumferential and / or axial direction.

[0098] According to an optional embodiment of the invention as described in the third aspect, the vehicle wheel assembly comprises more than one shell. Multiple shells can form a corresponding number of Helmholtz volumes, thus improving the effect. Preferably, the vehicle wheel assembly comprises exactly two shells. The two shells can be arranged diametrically opposite to the rim's axis of rotation. This improves the effect and prevents imbalance. Each shell can include a corresponding number of shell fastening devices, which can also be one. Each shell can have its own fastening device(s) that fastens only the corresponding shell. This means that each shell can be attached to and / or distributed on the rim independently of other shells.

[0099] According to an optional embodiment of the invention according to the third aspect, the wheel assembly or the rim has a valve or a valve hole, wherein the shell is arranged such that the connecting opening points away from the valve or a valve hole in the circumferential direction of the rim. If the wheel assembly comprises multiple shells, all connecting openings can point away from the valve or a valve hole. This orientation of the connecting opening(s) prevents the ingress of any fluid(s) into the Helmholtz volume(s) that could enter the tire cavity through the valve. Such a fluid could be self-sealing fluid for sealing an unwanted puncture in the tire through which air is escaping. Such fluids are conventional aids for repairing punctures in tires.

[0100] According to an optional embodiment of the invention as described in the third aspect, the shell fastening device, or at least one, is arranged on the outer edge(s) or sides of the shell, or within the outer circumference of the shell. The outer circumference is defined in the radial direction. The first alternative is advantageous because the shell fastening device(s) is / are then arranged close to the outer edge(s), which is beneficial for sealing. Less force is required. Furthermore, this arrangement allows the shell fastening device to simultaneously secure the shell and seal the Helmholtz volume. The second alternative is advantageous because it saves installation space, as no fastening means needs to be provided outside the shell or on its outer edges. Preferably, the shell fastening device is surrounded by the Helmholtz volume, preferably at its respective outer circumference.If more than one shell fastening device is assigned to the shell, all shell fastening devices can be surrounded by the Helmholtz volume, preferably at their respective outer circumferences. The shell fastening device(s) can be arranged at a distance from the outer edge(s) or longitudinal sides of the shell extending in the circumferential direction, and / or from the outer edge(s) or transverse sides of the shell extending in the axial direction.

[0101] According to an optional embodiment of the invention according to the third aspect, when viewed in the radial direction, if there are exactly two shell fastening devices, they have a linear arrangement extending in the circumferential direction; if there are exactly three shell fastening devices, they have a triangular arrangement; if there are exactly four devices, they have a quadrilateral arrangement.

[0102] According to an optional embodiment of the invention as described in the third aspect, the shell is airtightly attached to the rim and / or the shell mounting device, preferably by at least one sealing device. The adjacent areas of the shell on the one hand and the rim and / or the shell mounting device on the other hand are airtight. It is understood that the Helmholtz volume is not completely closed, but has a neck through which the Helmholtz volume is connected to the shell's surroundings. The surroundings can be a tire cavity if a tire is mounted on the rim. Preferably, the shell is completely sealed against its surroundings, with the exception of the connecting opening. It is conceivable that the shell rests directly against the rim and / or the shell mounting device in an airtight manner without a specifically provided sealing means.It is conceivable that the shell fastening device and / or the fastening connection are designed such that the force applied to the shell in the radial direction is sufficient to ensure an adequate seal. The at least one sealing device can be an elastic seal (for example, a rubber gasket), adhesive tape, or a strip of tape. However, the at least one sealing device can also be an adhesive seam, a weld seam, or a brazed seam. The at least one sealing device can be added to / attached to either the shell or the rim, or both.

[0103] According to an optional embodiment of the invention as described in the third aspect, the sealing device comprises an outer sealing device arranged on an outer circumference of the Helmholtz volume and / or at least one inner sealing device arranged on an inner circumference of the Helmholtz volume. Both sealing devices seal the Helmholtz volume against the shell environment. The inner sealing device(s) creates a region within the outer circumference of the shell that is sealed against the Helmholtz volume. A shell fastening device can advantageously be arranged in this region. This is particularly advantageous if the shell has a fastening hole in which the shell fastening device is arranged. Preferably, each shell fastening device is sealed by a single inner sealing device.Preferably, the shell has only a single external sealing device, preferably one-piece.

[0104] According to an optional embodiment of the invention, as described in the third aspect, the shell includes a mounting hole for the shell mounting device. Preferably, the mounting hole is surrounded on its outer circumference by the Helmholtz volume or is arranged adjacent to the Helmholtz volume. The mounting hole preferably extends in a radial direction. Preferably, each shell mounting device is arranged in a mounting hole; more preferably, each shell mounting device has its own mounting hole. The mounting hole can be a through hole. It can extend from the outer circumference of the shell to the outer circumference of the rim. This facilitates easy attachment to the shell mounting device. The wall of the mounting hole can extend in a radial direction; it can surround the shell mounting device.It is conceivable that the wall forms a groove to accommodate a sealing device, preferably at its free end. This simplifies the geometry and achieves a good seal. The groove can be an annular groove and / or located at the end of the wall.

[0105] According to an optional embodiment of the invention as described in the third aspect, the shell itself has no holes. The shell can, at least for its attachment, have no holes. This makes its production very easy and inexpensive.

[0106] According to an optional embodiment of the invention as described in the third aspect, the shell can delimit only a single Helmholtz volume. This also makes the geometry less complex and reduces manufacturing and assembly costs.

[0107] According to an optional embodiment of the invention as described in the third aspect, the shell comprises at least one flange, preferably two flanges on each of its transverse sides, with the shell fastening device being attached to the flange(s). The shell can thus be longer in the circumferential direction, and the fastenings do not occupy any space within the Helmholtz volume.

[0108] According to an optional embodiment of the invention as described in the third aspect, the shell forms a Helmholtz neck, preferably with the rim and the shell together defining the neck. The neck of the shell can be designed as a groove. The groove can be bottomless, i.e., open towards the rim. This results in a very simple geometry that can be produced cost-effectively. The connecting opening can be positioned at the end of the neck that points away from the Helmholtz volume. At the other end, the neck is open towards the Helmholtz volume. The connecting opening and / or the neck can be arranged on a transverse side of the shell, with the transverse side running in the axial direction.

[0109] According to an optional embodiment of the invention as described in the third aspect, the Helmholtz volume can be arranged laterally adjacent to the neck, preferably on both longitudinal sides of the neck. The Helmholtz volume can extend along the neck at least on one side of the neck, preferably on both sides. This saves installation space, since the neck does not protrude freely from the shell, but is compactly recessed slightly into the shell. It is conceivable that the shell separates the neck from the Helmholtz volume in its longitudinal direction by means of a groove(s) and / or a wall(s), which it preferably forms itself. The groove(s) or the wall(s) can run parallel to the neck. This increases the Helmholtz volume by those areas on the side of the neck.

[0110] According to an optional embodiment of the invention as described in the third aspect, it is conceivable that the groove(s) and / or the wall(s) between the Helmholtz volume and the neck are sealed, preferably by a sealing device, more preferably by the external sealing device. This means that even with this design, a single external sealing means may be sufficient. This seal separates the longitudinal sides of the neck from the Helmholtz volume.

[0111] According to an optional embodiment of the invention as described in the third aspect, the shell is a plastic part or a metal part and / or is an injection-molded part or a thermoformed part. Both plastic (e.g., thermoplastic or thermosetting plastic) and metal (e.g., aluminum) are suitable for cost-effective and time-efficient injection molding and thermoforming of the inventive shell. A plastic shell is easy to manufacture because it has no base. Thus, no complex processes, such as blow molding, are required for its production. A metal shell is particularly suitable for welding. The metal shell can be a sheet metal shell. Furthermore, a metal shell is more resistant to forces, so that, for example, forces occurring during the attachment of the shell can be accommodated with higher tolerances. A metal shell is robust and does not break or become loose under tire pressure.

[0112] Directional terms, such as circumferential direction, radial direction, axial direction, and rim axis of rotation, are to be understood as referring to the rim unless otherwise specified. Axial and axial direction are parallel to the longitudinal axis or axis of rotation. Radial and radial direction are perpendicular to the longitudinal axis. The circumference and circumferential direction are about the axis of rotation. Production means a process by which a component is manufactured. Assembly means a process by which a component is fixed at or in its intended functional location. If components or features are disclosed more than once, embodiments and advantages described for only one of the components / features are also optionally disclosed for the other corresponding components / features.

[0116] Fig. Figure 1 conceptually presents a first aspect of the invention. A vehicle wheel assembly 1 is shown, comprising a wheel 100, which includes a rim 102, at least one shell fastening device 200, which is attached to the rim 102 by a material-fit connection 202, and a shell 300, which is arranged on the rim 102 by means of the shell fastening device 200, which provides a fastening connection 204 for this purpose. The rim 102 and the shell 300 together define a Helmholtz volume V.

[0117] The shell fastening device 200 and the shell 300 form a set of 4.

[0118] Fig. Figure 2 conceptually presents a second aspect of the invention. It shows a vehicle wheel arrangement 2 comprising a wheel 100, which includes a rim 102, and a shell 300, which is directly attached to the rim 102 by a material-bonded connection 202, wherein the rim 102 and the shell 300 together define a Helmholtz volume V.

[0119] Fig. Figure 3 conceptually represents a third aspect of the invention. It depicts a vehicle wheel assembly 3 comprising a wheel 100, which includes a rim 102, at least one shell fastening device 200, which is attached to the rim 102 by a frictional connection and / or a positive-locking connection 203, and a shell 300, which is arranged on the rim 102 by the shell fastening device, wherein the rim 102 and the shell 300 together define a Helmholtz volume V, the shell fastening device 200 being fixed in a fixing hole 110 in the rim 102. The shell fastening device 200 and the shell 300 form a set 4.

[0120] Fig. Figures 2-9 show an embodiment according to the first aspect of the invention in various views. These figures are described together. The wheel 100 comprises the rim 102 and a disc 104, which forms spokes 112. The rim 102 has an outer circumferential surface 106, which is cylindrical or conical. As can be seen, there is no tire yet on the rim 102. The tire defines a tire cavity with the rim 102. A valve hole 108 is formed in the rim 102. A valve in the valve hole 108 is also not shown.

[0121] The fastening connection 204 is created by notches, but is not limited to this. The shell 300 has two shell fastening devices 200. The shell fastening devices 200 are spaced apart from each other in the circumferential direction U, with a linear arrangement extending in the circumferential direction U. For clarity, only one of these shell fastening devices 200 is described below, but both are identical. The shell fastening device 200 comprises a first fastening partner 206, which is attached to the rim 102 by the material-fit connection 202. The first fastening partner is a pin 206.1, which extends in the radial direction R and has no undercut. The pin 206.1 has a cylindrical shape, preferably at least in the fastening area for a second fastening partner 208.The shell fastening device 200 comprises the second fastening partner 208, which is a separate part from the shell 300 and is permanently attached to the shell 300. The second fastening partner 208 is a snap-on locking plate 208.1, which includes a ring from which elastic clamping tongues 216 project radially inwards. The shell 300, together with the second fastening partner 208, is attached to the first fastening partner 206 in the radial direction R. The clamping tongues 216 then press into the first partner 208 with their free ends, forming notches 218 there. Thus, the notches 218 are a cutting notch.

[0122] The shell fastening device 200 is a separate part from the rim 102 and the shell 300. The shell fastening device 200 is attached to the outer surface 106 of the rim 102. The shell 300 is positioned on the outer surface 106 of the rim. The shell 300 is secured in a stationary and immovable position relative to the rim 102. The fastening connection 204 and / or the shell fastening device 200 press the shell 300 against the rim 102. The shell fastening device 200 consists of two parts 206 and 208.

[0123] The shell 300 is a half-shell, open towards the rim 102 and bottomless. The shell 300 has no undercut in the radial direction R. The shell 300 is a single piece, preferably made of one material. The shell delimits only a single Helmholtz volume V, which has a connecting opening 310. Through the connecting opening 310, the Helmholtz volume V is open towards a tire cavity and is delimited by the shell 300 and the rim 102.

[0124] The shell 300 forms a bottomless Helmholtz neck 314, the neck 314 being delimited by the rim 102 together with the shell 300. The neck 314 is designed as a channel that is bottomless, i.e., open towards the rim 102. The connecting opening 310 is positioned at the end of the neck 314 that faces away from the Helmholtz volume V and away from the valve hole 108. On the other side, the neck 314 is open towards the Helmholtz volume V. The connecting opening 310 and / or the neck 314 can be arranged on a transverse side 320 of the shell 300. The Helmholtz volume V is arranged laterally adjacent to the neck 314 on both longitudinal sides of the neck 314. The Helmholtz volume V thus extends along the neck on both longitudinal sides of the neck 314. The shell 300 separates the neck 314 from the Helmholtz volume V in its longitudinal direction by grooves 312 or walls, the grooves 312 or walls being formed by the shell 300 itself.The groove(s) 312 and / or the wall(s) run parallel to the neck 314.

[0125] The shell 300 includes a mounting hole 308 for each of its two shell mounting devices 200. The mounting holes 308 are surrounded on their outer circumference by the Helmholtz volume V. The mounting hole 308 extends in the radial direction R, with each shell mounting device 200 being arranged in a respective mounting hole 308, preferably each shell mounting device 200. The mounting holes 308 are through holes extending from the outer circumference of the shell to the outer circumference of the rim or to the outer surface 106 of the rim 102. The wall 322 of each mounting hole 308 extends in the radial direction R and surrounds the shell mounting device 200. Each wall 322 forms an annular groove 324, which receives a sealing device, preferably an inner sealing device 305, at its free end.

[0126] The shell 300 is airtightly attached to the rim 102 by an outer sealing device 304, which is arranged on an outer circumference 316 of the Helmholtz volume V, and two inner sealing devices 305, which are arranged on an inner circumference of the Helmholtz volume V. It is understood that the Helmholtz volume V is not completely closed, but has a neck 314 through which the Helmholtz volume V is fluidically connected to the environment surrounding the shell 300. The shell 300 is completely sealed against the shell environment, with the exception of the connecting opening 310. The sealing devices 304 and 305 are rubber seals. The inner sealing devices 305 each create a region within the outer circumference 316 of the shell 300 that is sealed against the Helmholtz volume V. A shell fastening device 200 is arranged in each of these areas.Each shell fastening device 200 is sealed by a single internal sealing device 305. The shell 300 has only a single external sealing device 304, which is a single piece. Furthermore, the grooves 312 and / or the walls between the Helmholtz volume V and the neck 314 are also sealed by the single external sealing device 304.

[0127] The vehicle wheel assembly 1 comprises exactly two shells 300, which are arranged diametrically opposite to the rim rotation axis X. Each shell 300 has a corresponding number of shell fastening devices 200, with the respective connecting openings 310 pointing away from the valve hole 108 in the circumferential direction U.

[0128] The shell fastening device 200 is arranged within the outer circumference 316 of the shell 300, as seen in the radial direction R. The shell fastening device 200 is arranged at a distance from the outer edges 306 or longitudinal sides 318 of the shell 300, which extend in the circumferential direction U, and from the transverse sides 320 of the shell 300, which extend in the axial direction A.

[0129] Fig. Figure 10 shows the shell 300 as viewed from the rim 106. As can be seen, the shell has no undercuts and the only external sealing device 304 runs along the outer circumference, but also between the Helmholtz volume V and the neck 314 in the longitudinal direction of the neck 314.

[0130] Fig. 11 and Fig. Figure 12 illustrates the fastening connection 204 in more detail by means of notches. Fig. Figure 11 represents a clip-on locking plate 208.1, which is a second fastening partner 208 along the longitudinal axis. The clamping tongues 216 project radially inwards. Each tongue has a free end for creating a notch 218 in the first fastening partner 206. Fig. Figure 12 represents the mounted state in which both partners 206, 208 are fastened by notches.
