The present disclosure pertains to wheels and, more particularly, to a wheel system for vehicles that provides for a base wheel and an adaptive attachment of interchangeable decorative wheel faces.
The automotive wheel industry continues to be an integral part of automotive design, functionality, and customization. The idea of the integrated wheel arises from the opportunity to incorporate the full use of the wheel that is fully customizable by the consumer. The automotive wheel market has to meet stronger governmental standards amidst balancing changing consumer styling trends and demands. The current wheel market is a multi-billion dollar industry dominated by the OEM end-user which is compounded by the aftermarket end-user. Innovation in this segment is becoming increasingly vital given the need to decrease unsprung weight or rotational mass while keeping desirable aesthetic properties.
The present disclosure is directed to an integrated wheel design and structure that takes full advantage of all aspects of the wheel, allowing for the ability to maximize offset, concavity, diameter, and reduction of weight to maximize circular velocity in certain applications. The present disclosure reduces manufacturing cost without sacrificing the desirable ornamental properties. In fact, it exponentially increases the ornamental design capabilities, thus allowing for both the OEM and consumer or end-user to keep up with trends without costly re-investment.
In accordance with another aspect of the present disclosure, a multi-piece wheel assembly is provided that incorporates an adaptive hub attachment that also enables exchanging of ornamental faces or the hub itself. This assembly will allow car enthusiasts to easily change the look of their automotive wheels. The adaptive hub attachment can simulate the appearance of a center lock wheel appearance or be incorporated into the design of the wheel itself. The assembly, in one implementation, has a base wheel designed to support the ornamental face, a replaceable ornamental face plate, and an attachment assembly to attach the ornamental face plate to the base wheel.
In accordance with another aspect of the present disclosure, a three-piece wheel assembly is provided that provides a simulated center lock wheel look that also enables exchanging of an ornamental center hub attachment. This assembly will allow car enthusiasts to easily change the look of their automotive wheels while maintaining a center lock wheel appearance.
The assembly, in one implementation, has a base wheel, a replaceable ornamental face plate, and an attachment assembly to attach the ornamental face plate to the base wheel.
In accordance with another aspect of the present disclosure, the wheel assembly includes three components: a base wheel, a center lug conversion, and at least one (and preferably more than one) interchangeable center hub attachment or ornamental face plate.
In accordance with another aspect of the present disclosure, the base wheel includes a standard five-lug attachment although it can accommodate a 4-lug or even a 1-lug configuration, and it can include in one implementation a deep offset to provide as much exterior space for a variety of attachments. The base wheel will have as little material as possible for weight reduction. It can employ multiple designs centered on light weight strength and stability, including without limitation, thin spokes and spokes having a more blade-like shape.
In accordance with yet a further aspect of the present disclosure, the adaptive center lug conversion device is attached to the center hub of the base wheel from the back and extends outward. The adaptive hub center lug conversion device is for appearance only and does not bear the weight of the vehicle.
In accordance with still yet another aspect of the present disclosure, the center hub attachment or ornamental face plate differs from a hubcap, beauty rim, or wheel cover as it moves away from conventional methods of producing decorative faces and attachment points. The ornamental face takes advantage of the base wheel and its attributes to cover only as much as required to achieve the desired design. This allows the design to keep open areas that can expose the brake system and still maintain the look of a true wheel. The hub cap or beauty rim also adheres to the wheel in one plane, which differs drastically from the aforementioned face that incorporates a design traversing multiple planes. It also differs from a typical wheel currently using the end ornamental design as the weight bearing surface. The new ornamental face is integrated into the base wheel providing structure and uniformity to the ornamental face. By integrating the ornamental face to the base wheel it provides a stable attachment to not only composite material but also metal faces. It attaches to the center lug conversion device using a secure locking mechanism. It fits into the base wheel and can use the existing space and structures such as lug nuts as internal stabilization points.
In accordance with still yet another aspect of the present disclosure, the center hub attachment or ornamental face plate is similar to a hubcap, beauty rim, or wheel cover that is decorative only. It attaches to the center lug conversion device using a secure locking mechanism. By allowing center attachment, the weight and design of the ornamental faces can dramatically increase compared to a typical hubcap or beauty ring. The base wheel design is integral in providing this support system to bear more weight and stabilize ornamental faces. The lockable center attachment is a secure attachment with good clamping force. Use of the center hub and base wheel structure will prevent movement and bear the outward centrifugal forces being applied. Use of a secure center attachment will (in conjunction with variations in center offsets) maintain most of the weight closer to the center of the barrel, alleviating weight disturbances in the wheel. Overall, the accessibility the center hub provides will allow interchangeability of ornamental faces with different designs. Designs that take advantage of the concavity of the wheel will be much easier to achieve and deliver better aesthetics, quality and appearance than any hub cap or beauty ring.
As will be readily appreciated from the foregoing, a variety of center hub attachments will give the user a choice and enable changing out the attachments at any time. The combination of the center lug conversion device and the center hub attachment provide the appearance of an authentic center lug wheel assembly by hiding the lug nuts of the vehicle if desired, although this is not necessary and the ornamental face could be designed to expose the lugs.
The base wheel and center hub combination allow for various adjustments to be made that will, in turn, affect the end design, having the ability to change the depth of the ornamental faces either by replacing solid faces or controlling the center hub to allow depth and angle variations. The ability to change the depth or angle will, in turn, add different design features. The ability of the center hub to accept different depth allows for axial movement. Adding a lock nut capable of housing independent ornamental faces or spokes onto the center hub adds the ability to change depth, and hence design, by moving the ornamental faces along the rotational axis of the center hub.
The integrative wheel technology disclosed herein merges both parties' interests. It accomplishes this by simplifying and dividing the current manufacturing process. A core base wheel design takes advantage of all aspects of the wheel. The integrative wheel advances design by moving away from the typical restrictions placed by the end ornamental design. Currently, the end design maintains the weight of the vehicle. Integration of the base wheel will sustain the weight of the vehicle. This would, in turn, not restrict the end-user's ability to freely change designs that are no longer tied to the weight bearing component. The base of the integrated wheel only incorporates the necessary material required to safely maintain the weight and exertional forces created by the vehicle. This can be accomplished by minimizing the design and distributing the material that attaches the hub/center of the wheel to the wheel barrel. If the distance of the hub/center is moved and a negative offset is incorporated, this would create a more useable surface area on the face of the wheel. Fabricating multiple attachment points from the center of the wheel distributes the weight carrying capacity of the wheel. The attachment points can have multiple designs and variations such as being slightly angled, creating a propeller-like spoke to maximize surface area and also to hide the rear portion of the base wheel. Varying the amount of material and distribution of the center will also allow for different ornamental designs to be applied to the end product. The base wheel attaches to the hub of the vehicle in conventional methods either by using a multi-lug attachment or a center lug attachment.
The foregoing and other features and advantages of the present disclosure will be more readily appreciated as the same become better understood from the following detailed description when taken in conjunction with the accompanying drawings, wherein:
In the following description, certain specific details are set forth in order to provide a thorough understanding of various disclosed implementations. However, one skilled in the relevant art will recognize that the present disclosed implementations may be practiced without one or more of these specific details or with other methods, components, materials, etc. In other instances, well-known structures or components or both that are associated with the environment of the present disclosure have not been shown or described in order to avoid unnecessarily obscuring descriptions of the implementations. For example, these well-known structures or components include the structure and design of wheel spindles, axles, and the like to which a wheel and associated tire are mounted on a vehicle. Similarly, the tire to be mounted on the wheel assembly of the present disclosure is not illustrated or described herein in order to provide a clear and unobstructed view of the wheel assembly formed in accordance with the present disclosure.
Unless the context requires otherwise, throughout the specification and claims that follow, the word “comprise” and variations thereof, such as “comprises” and “comprising” are to be construed in an open inclusive sense, that is, as “including, but not limited to.” The foregoing applies equally to the words “including” and “having.”
Reference throughout this description to “one implementation” or “an implementation” means that a particular feature, structure, or characteristic described in connection with the implementation is included in at least one implementation. Thus, the appearance of the phrases “in one implementation” or “in an implementation” in various places throughout the specification are not necessarily all referring to the same implementation.
As used herein, the term “wheel” refers to a barrel having a center hub and at least one rim associated with it on which is mounted a tire, typically a pneumatic tire. Details concerning the association between the barrel, the rim, and the hub, such as the use of intermediate connection members, including without limitation spokes, are described in more detail hereinbelow. By way of general description, the wheel integration technology described herein simplifies and divides the current manufacturing process. A core base wheel design takes advantage of all aspects of the wheel. The base wheel advances design by moving away from the typical restrictions placed by the end ornamental design. Currently, the typical end design maintains the weight of the vehicle. The base wheel of the present disclosure will sustain the weight of the vehicle while not restricting the end-user's ability to freely change ornamental wheel face designs. The base wheel only utilizes the amount of material required to safely maintain the weight and the exertional forces created by the vehicle. This can be accomplished by minimizing the base wheel design and distributing the material that attaches the hub or center of the wheel to the wheel barrel. The base wheel provides integral support to the ornamental face by using surfaces on the posterior aspect that fit and sustain various portions of the ornamental face design. The base wheel and center hub provide the ability to have unsupported spokes or ornamental faces. This has the ability to drastically reduce overall end weight of the wheel as the unsupported structure only needs to have the desired design as it does not bare the weight of the vehicle. If the distance of the hub or center is moved so that a negative offset is obtained, this would create a more useable surface area on the face of the wheel. This surface area combined with the ability to quickly detach faces or spokes allows the end user to drastically change the overall end design of the ornamental face.
Fabricating multiple attachment points from the center of the wheel distributes the weight carrying capacity of the wheel. The attachment points can have multiple designs and variations such as being slightly angled creating a propeller like spoke to maximize surface area and also hide the rear portion of the base wheel. Varying the amount of material and distribution of the center will also allow for different ornamental designs to be applied to the end product. The integrated wheel attaches to the wheel rotor of the vehicle in conventional methods either by using a multi-lug attachment or a center lug attachment.
The center of the integrated wheel utilizes a unique attachment point. It can be incorporated into the initial manufacturing process of the wheel or united to the base wheel. This center attachment point creates the integral part of the base wheel. The center attachment point allows for a secure method to attach different ornamental surfaces to the base wheel. This is accomplished with a fastener-type screw-on cap and coupling attachment for both safety and ability to quickly release and change the ornamental face plate. In the case of the multi-lug hub, low profile lug nuts are used to attach the base wheel. In this case the ornamental surface can be designed to multiple different specifications.
The different ornamental face plate designs can hide the lugs if desired to thereby create a center lug wheel look. The center lug wheel incorporates the center attachment point either from the hub attachment itself (if the vehicle uses a hub-type conversion to a center lug) or secures to the center lug creating the same ability to secure ornamental face plates. The center cap and attachment component allows space for a locking mechanism to protect the ornamental face plate and wheel from theft. This also adds another layer of safety. The ornamental face plate will have a backing with minor ridges and distal insertion points at the wheel barrel that match the base wheel. The distal ridges or insertion may be used if required to stabilize the ornamental face plate during high revolution or wind interference. This would be implemented primarily for properly securing the distal edges of the face (spokes) especially when using more flexible composite material.
Another aspect of the present disclosure is the ability to change the depth of the ornamental face and ornamental spokes inside the barrel of the wheel. This differs from a typical hub cap or beauty ring in the ability to cross different planes in the wheel barrel space. In addition, none of the prior designs can stay attached when there is distortion of the wheel to which they are attached. The structure of the present disclosure has a fixed attachment to a center attachment point on the base wheel, which means any distortion of the wheel barrel on the base wheel does not affect the attachment of the ornamental face to the base wheel.
Referring next to the drawings,
In this implementation, the wheel assembly 20 includes a base wheel 24 formed of a barrel portion 26 and a centrally located wheel hub 28 in the interior of the barrel portion 26. The wheel hub 28 includes a center attachment point 30 to which can be attached one from among a plurality of different ornamental face plates 32 using a threaded fastener 34, which when combined form the wheel assembly 20.
The barrel portion 26 of the base wheel 24 includes the cylindrical-shaped barrel 36 having an annular exterior rim 38 and an annular interior rim 40 formed around the exterior and interior perimeters, respectively, of the cylindrical-shaped barrel 36. The wheel hub 28 in this implementation is solid from the exterior rim 38 to the point where it meets the center attachment point 30. In other words, it is dished in appearance and devoid of openings such as slots, and has no spokes, blades, or the like. However, it is to be understood that other configurations may be used for the wheel hub 28, including spoked, bladed, slotted, and variations thereof for weight reduction (to sustain the weight of the vehicle and create windows to allow for visualization of braking components and cooling). The size, shape, and placement of the same features may also be dictated by ornamental design considerations and to appeal to consumers based on latest styles and trends. Although the weight of the base wheel 24 is preferably as light as possible, removal of material to achieve lighter weight may still be done, with or without deference to appearance, cosmetic appeal, and latest ornamental trends and consumer preferences.
The center attachment point 30 may be integrally formed with the wheel hub 28, such as in the forging stage, or welded in place during fabrication, or it may be removably attached to the wheel hub 28 using conventional attachment methods that are readily commercially available and will not be described in detail herein. The center attachment point 30 includes five openings 42 sized and shaped to receive five mounting lugs 44 projecting from the vehicle rotor 23. Five lug nuts 46 are shown for threadable engagement with the five mounting lugs 44 to hold the base wheel 24 in place on the vehicle rotor 23 in a conventional manner. (Shown five lug configuration but one or more lugs could be used.) Extending from the center attachment point 30 is a threaded post 48 having exterior threads 50. In some implementations, the post may have a hollow internally threaded axial bore with a smooth exterior surface, a threaded exterior surface with smooth internal bore, or the exterior surface may be threaded in combination with internal threads on the internal axial bore. The threads may be right-handed or left-handed oriented threads, depending on the direction of rotation of the wheel assembly 20 when mounted on the vehicle.
This post, because of where it is located at the center of the hub and its purpose built construction, can hold varying amount of weight securely and safely. For example it can hold larger heavy metal faces but will not flex or contort under forces like a hub cap.
The ornamental face plate 32 shown in
In the implementation shown in
In addition, the center attachment point 84 includes an annular channel 98 interior of the shoulder 94 that is sized and shaped to receive an annular collar 100 extending from an interior side of the ornamental face plate 32. When the ornamental face plate 32 is installed on the post 92 and slid onto the shoulder 94, the annular collar 100 will be slidably received inside the annular channel 98, providing more stability in the positioning of the ornamental face plate 32 during installation and use.
As will be readily appreciated from the foregoing, the base wheel is easier to manufacture and more simply reproducible than current decorative wheels. This only requires tooling modifications for offset, diameter and rigidity specifications and will decrease manufacturing costs. It also decreases the environmental footprint of the manufacturing process. The base wheel can apply multiple types of manufacturing processes such as forging, casting, multi-piece and flow-forming, amongst others, to achieve desired structural capabilities. Different types of materials can also be used, such as aluminum, magnesium, or composite type carbon fiber to create lightweight forms. Base wheel technology will essentially decrease the overall weight of the base wheel despite material or process used. This, in turn, will decrease unsprung weight in the wheel, enhancing performance/handling and improve fuel economy. If at any point it is desired to run the wheel at its lightest capability, then it only requires the end-user to remove the ornamentation and center attachment cap. The base wheel essentially uses the least amount of material to bear the weight of the vehicle; hence it is the lightest that can be produced safely. The base wheel allows for a cosmetically appealing, lightweight final product that still adheres to current designs while having the ability to add decorative features as desired. The base wheel is set apart by perpetuating these desirable design features, like the spacing of the base wheel attachment points (spokes) to visualize the caliper and rotor of a vehicle. This allows for desired visualization of these components and cooling of the braking system in the performance realm as well as aesthetics in the customization world.
The center attachment point on the wheel pushes the capability of customization to new levels. Using the base wheel as a springboard, the methodology of using the whole wheel creates new possibilities. Changing from a concave (negative) look offset to a more neutral or positive look is facilitated with the present disclosure. The locking mechanism can be removed and the cap untightened, to swap the ornamental face plate. Having the capability of changing the look of a wheel is a welcomed and overdue innovation in the automotive wheel realm. This integrated wheel technology drives the cost of creating easily interchangeable wheel faces down. This cuts down on waste and amount of product needed to create a whole new wheel. This also leads to the use of different types of materials to comprise the face of the wheel, such as composites or metals that usually require large amounts of machining to attain different finishes and colors.
Wheel integration technology has the potential to innovate multiple aspects of the automotive wheel market. The base wheel allows for the ability to easily swap and change faces, colors, and multiple designs can be placed on the base wheel. This is attained without having any load bearing surfaces. Customization can also be applied to the center lug/cap, incorporating different designs and colors. Different types of materials add flare to finishes, and composites play a vital role in weight reduction. This concept of interchangeability adds new dynamic to the wheel industry. Both the OEM and end-user benefit from this type of customization capability.

In this implementation, the center locking assembly 122 includes a king nut 124 having internal threads 126 sized and shaped to engage the exterior threads 118 of the wheel post 114. The outer exterior perimeter of the nut 124 is keyed with projections 128 to accept a similarly keyed socket (not shown) to provide security in the attachment of the face plate 104 to the wheel 102.
The center locking assembly 122 includes a center cap 130 sized and shaped to be received over the nut 124 and a sealing ring 132 that is sized and shaped to be received in a recess 134 in the cap 130. In accordance with one aspect of this implementation, the cap 130 has an annular interior collar with exterior threads, preferably reverse threads (dependent on the side of the vehicle), that threadably engage with interior reverse threads formed in a hollow interior of the wheel post 114. The recess 134 in the cap 130 is keyed to accept a tool for turning the cap 130 when the cap 130 is received on the wheel post 114. The sealing ring 132 is preferably formed of compliant material to enable insertion of the sealing ring 132 in the circular recess 134 with a tight fit.
In accordance with another aspect of the present disclosure, the ring 140 may be snapped on to the wheel 102 or threadably engaged with the rim of the wheel 102 as described more fully below.

It is to be remembered that the ornamental face does not bear weight, hence the design of the face plate is not limited by that fact. Current wheel aesthetics are tied to holding weight because extra material is needed to hold the vehicle weight as well as to support the wheel design. This is inefficient, whereas the present design uses less material with resulting less weight. As seen in

This implementation can also be utilized with an outer collar described below with respect to
The ornamental face plate 212 attaches to the stepped center post 208 by sliding the collar 232 over the post 208 until the ball detents 224 on the post 208 engage the respective openings 230 in the collar 234. The stepped nature of the post 208 provides a limit to the axial insertion of the ornamental face plate 212 on the post 208 to provide for different depths of insertion and to accommodate different depth faces. In addition, the stepped post 208 enables the post 208 to accept ornamental face plates that have collars of different diameters or to accept two ornamental face plates in a stacked relationship on the post 208. While two stepped faces 226, 228 are shown, it is to be understood that additional stepped faces may be formed on the post 208.

In the first attachment method, the ring 280 has tabs 284 with a central opening 286, each tab 284 sized and shaped to be slidably received in an opening 288 formed between the distal ends 290 of the spokes 292 on the ornamental face plate 282. A U-shaped terminal end 294 is formed at the distal ends 290 to connect each pair of spokes 292 together. The terminal end 294 is sized and shaped to extend over and bear against the annular face 296 of the ring 280. The second attachment method uses two female slots 298 formed in the annular face 296 of the ring 280 that are sized and shaped to receive the sidewalls 299 depending from the spokes 292 on the face plate 282.

The various implementations described above can be combined to provide further implementations. For example, the ring can have channels that are sized and shaped to receive a component on the wheel and in which the ring then twists and locks in place on the wheel.
For example, the ornamental face plate 32 can be provided with a locking mechanism (not shown) as one unit to lock in place on the post. This can include a snap-on version for ease of installation and removal.
As shown in
The barrel portion 456 of the base wheel 452 includes the cylindrical-shaped barrel 460 having an annular exterior rim 462 and an annular interior rim 464 formed around the exterior and interior perimeters of the barrel 460, respectively, of the barrel 456. The wheel hub 458 in this implementation is not solid from the exterior rim 462 but has the spokes 454 described above. However, it is to be understood that other configurations may be used, including solid dished, bladed, slotted, and variations thereof for weight reduction (to sustain the weight of the vehicle). The size, shape, and placement of these features are also determined by ornamental design considerations and to an appearance that has appeal to consumers based on latest styles and trends. Although the weight of the base wheel 452 is preferably as light as possible, removal of material to achieve lighter weight may still be done, with or without deference to appearance, cosmetic appeal, and latest ornamental trends and consumer preferences.
The wheel hub 458 has the center attachment point 466 that may be integrally formed with the wheel hub 458, such as in the forging implementations, or welded in place during fabrication, or it may be removably attached to the wheel hub 458 using conventional attachment methods that are readily commercially available and will not be described in detail herein. The center attachment point 466 includes five openings 468 sized and shaped to receive five mounting lugs projecting from the vehicle rotor as described above with respect to
The adjustable depth ornamental assembly 453 includes a center post 470 structured to attach to the center attachment point 466 to move axially along the X-X rotational axis of the base wheel 452. In one implementation, the center post 470 has a hollow cylindrical interior with a first set of external threads 471 sized and shaped to engage internal threads on the center attachment point 466. A locking screw (not shown) can be threadably engaged with a side wall of the center post 470 to bear against the center attachment point 466 and prevent rotation of the center post 470 relative to the center attachment point 466. Threading the center post 470 clockwise onto the center attachment point 466 changes the position of the center post 470 relative to the base wheel 452 by moving it deeper into the interior of the base wheel 452 (unless reverse threads are used, then the opposite would be true). Likewise, turning the center post counterclockwise would move the center post in the opposite direction so it would move to be more shallow in the interior of the base wheel 452.
Attached at radially spaced attachment points on the exterior of the center post 470 are arms 472, each arm 472 attached to a yoke 474 at a proximal end of the arm 472. Attached for pivotal movement to each respective yoke 474 are spoke covers 476 that are sized and shaped to cover the exterior face of the base wheel spokes 454, providing an ornamental appearance to the base wheel spokes 454. Each spoke cover 476 includes a ball 478 at a proximal end of the arm 472 of the spoke cover 476 that is fit into the yoke 474, and can be held in place with a fastener 484 as shown in
The underside of each spoke cover 476 includes an alignment rib 486 positioned along a longitudinal axis of the spoke cover 476, generally extending along the mid-section of the spoke cover 476. The rib 486 includes a plurality of axially spaced semicircular slots 488 that are sized and shaped to fit over corresponding alignment projections 490 on the surface of the respective base wheel spoke 454. As shown in

Another feature and benefit of the present disclosure is the ability to leave open windows or spaces in the barrel of the base wheel, with or without the use of ornamental face plates, as described herein, to allow for visualization and cooling of brake components, or just cooling of vehicle components.
These and other changes can be made to the implementations in light of the above detailed description. In general, in the following claims, the terms used should not be construed to limit the claims to the specific implementations disclosed in the specification and the claims, but should be construed to include all possible implementations along with the full scope of equivalents to which such claims are entitled. Accordingly, the claims are not limited by the disclosure.
