Description

The present invention relates to a vehicle wheel, in particular a vehicle hybrid, with a manufactured from a metal material rim ring for receiving a tire and attached to the rim ring, made of a metal material wheel for releasable connection to a wheel of a vehicle according to the preamble of claim 1. Die The invention further relates to a method for producing a vehicle wheel.

Conventionally, vehicle wheels are made of metal materials, for example aluminum or magnesium materials and alloys thereof and the like (also referred to as light metal materials), as cast or forged parts and steel materials in sheet metal construction. Such vehicle wheels usually have a rim ring for receiving a tire and a wheel disc fixedly connected to the rim ring with a connection region (eg wheel hub) for detachable connection to a wheel carrier of a vehicle. As a wheel dish is in this case generally understood any connection structure which connects the rim ring mechanically with the connection area or the wheel hub. For example, the wheel dish may be substantially disc or bowl shaped, as is often the case with conventional steel wheels, which are often referred to as disc wheels. However, it may also be designed, for example, spoke-shaped. Still other forms of the wheel dish are also conceivable.

In addition to the vehicle wheels made purely from one or more metal materials, so-called vehicle hybrid wheels are also known, in which either either the rim ring or the wheel disc is completely formed from a fiber-reinforced plastic material. This construction of vehicle wheels primarily offers the advantage of reducing weight and / or further increasing the strength of the vehicle wheel.

For example, the JP H03-193501 A as well as the KR 10-1198625 B1 (also US 2012/0043014 A1 ) each have a vehicle hybrid, which has a rim ring formed from a fiber-reinforced plastic material for receiving a tire and connected to the rim ring, formed from a metal material wheel for connection to a wheel carrier of a vehicle.

From the US 2010/0320831 A1 On the other hand, a vehicle hybrid wheel is known, which has a rim ring formed from a metal material for receiving a tire and a wheel disc connected to the rim ring and made of a fiber-reinforced plastic material for connection to a wheel carrier of a vehicle.

Furthermore, the describes CH 710 074 A2 a vehicle hybrid wheel having a rim of a first material and a wheel rim of a second material bonded to the rim ring, at least one of the two materials being a fiber reinforced plastic material, such as fiberglass or carbon fiber material. Thus, the vehicle hybrid wheel may also be formed entirely of the fiber reinforced plastic material.

An aircraft hybrid wheel having a metal skeleton structure embedded at least partially in a fiber-reinforced plastic material describes U.S. Patent Nos. 3,846,974 US Pat. No. 8,042,766 B2 , The skeleton structure comprises metal rings interconnected by a plurality of metal rods, the metal rings forming, inter alia, the shape of a wheel hub and a rim flange for laterally guiding a tire. The aircraft wheel is designed in two parts, with two metal skeletons embedded in the fiber-reinforced plastic material being joined together, thus forming the complete aircraft wheel.

Furthermore, it is known to provide a wheel rim of a vehicle wheel tethered to a rim ring for receiving a tire on its visible surface (i.e., on its visible outside after mounting on the vehicle) with a pure plastic coating (i.e., without fiber reinforcement). The plastic coating is only decorative purposes, since it can be formed easier and cheaper with a higher degree of freedom design than a purely made of a metal material wheel.

Such vehicle wheels are for example from the US 4 786 027 A as well as the US 5 088 798 A known. These documents further describe a device for coating the vehicle wheel or its wheel bowl with the decorative plastic layer, wherein the coating device is a multi-part casting mold with a casting mold upper part which presses the wheel disk against a casting mold bottom part. The lower mold part forms a cavity with the wheel disc in the areas of the wheel disc to be coated, but through openings in the wheel disc, for example brake ventilation holes and / or wheel mounting holes, from the lower mold part by correspondingly shaped mold protrusions projecting into the respective openings for proper performance of the coating method must be closed.

The EP 0 457 070 A1 further discloses a vehicle wheel, the wheel disc also with a decorative plastic layer is coated, wherein as plastic material is chosen a galvanisierfähiger plastic to galvanize a chromium layer on this after the coating of the wheel disc.

Furthermore, from the GB 2 142 288 A a vehicle wheel with a rim ring for receiving a tire and a wheel rim connected to the rim ring, wherein at least a portion of the rim ring, in particular in the region of the rim holding the tire laterally on the rim ring with a plastic layer (without fiber reinforcement) is provided. The plastic layer, for example nylon, is intended to reduce wear of the rim ring due to its contact with the tire. According to one embodiment, the entire vehicle wheel may be provided with this plastic coating. This is intended to improve the corrosion resistance of the vehicle wheel. The plastic coating is applied to the vehicle wheel in the form of a plastic powder to be melted.

Against this background, the present invention seeks to provide an improved vehicle wheel, in particular vehicle hybrid, and an improved method for producing a vehicle wheel, in particular vehicle hybrid, indicate that can be produced with little and cost effort, a low weight and / or moment of inertia (rotating mass ) and at the same time has a high strength. In addition, the vehicle should also be visually attractive designable.

This object is achieved by a vehicle wheel with the features of claim 1 and by a method for producing a vehicle wheel with the features of claim 8. Further particularly advantageous embodiments of the invention disclose the respective subclaims.

It should be noted that the features listed individually in the following description can be combined with one another in any technically meaningful manner and show further embodiments of the invention. The description additionally characterizes and specifies the invention, in particular in connection with the figures.

It should further be noted that a conjunction "and / or" between two features and linking them together is always to be interpreted in such a way that in a first embodiment of the subject invention only the first feature may be present, in a second embodiment only the second feature may be present and in a third embodiment both the first and the second feature may be present.

According to the invention, a vehicle wheel, in particular a vehicle hybrid wheel, has a rim ring made of a metal material for receiving a tire and a wheel bowl connected to the rim ring and made of a metal material for detachable connection to a wheel carrier of a vehicle.

The rim ring may be formed in the axial direction of the vehicle wheel preferably hollow cylindrical, so that a contact surface for receiving the tire can be provided by the outside of the hollow cylinder wall. The wall thickness of the rim ring forming the hollow cylinder, that is, the traveling extension in its radial direction, in this case is significantly smaller than its axial extent. The rim ring thus has a (large) areal structure of its wall outside for receiving the tire.

As a wheel is generally understood any connection structure which mechanically mechanically connects the rim ring with a connection area, for example a wheel hub, which can be used in a conventional manner for releasably connecting the vehicle wheel to the wheel carrier of the vehicle. The wheel dish may have a substantially flat structure, for example disk-shaped or bowl-shaped. However, this is not mandatory.

The rim ring and the wheel disc may be made of one and the same metal material, for example of steel, aluminum, magnesium and the like, as well as alloys formed from such metal materials. However, this is not absolutely necessary, so that the rim ring and the wheel disc can also be formed of different metal materials.

According to the invention, both the rim ring and the wheel disc are at least partially coated with a fiber-reinforced plastic material, for example a plastic material reinforced with glass fibers or carbon fibers. As reinforcing fibers, fibers of a polymer material such as aramid and / or polyethylene fibers and the like may also be used. The plastic material is preferably a thermosetting plastic, such as polyester, epoxy or phenolic resin, and the like.

The provision of the fiber-reinforced plastic coating both on the metal rim ring and on the metal wheel bowl imparts a high degree of strength to the vehicle wheel, particularly with regard to higher vehicle operation Circumferential forces due to braking and acceleration moments and cornering forces due to changes in direction, while reducing weight. At the same time, such a vehicle wheel can be produced more cost-effectively than, for example, a vehicle wheel manufactured purely from a fiber-reinforced plastic material, since comparatively cost-effective, easily processed metal materials continue to be used. Preferably, the volume-related proportion of the metal rim ring and the metal wheel bowl on Gesamtfahrzeugrad is greater than the volume fraction of fiber-reinforced plastic coating, since the rim ring and the Radschüssel comparatively inexpensive from a metal material, in particular a light metal alloy, for example by casting or forging, produce in a conventional manner to let.

An advantageous embodiment of the invention provides that the rim ring and the wheel disc are coated on their respective outer sides and / or their respective inner sides substantially completely with the fiber-reinforced plastic material. In other words, the entire outer and / or inner surface or at least a substantially larger surface part of the outer side and / or the inner side of the rim ring and the wheel disc coated with the fiber-reinforced plastic material as a corresponding uncoated surface part. The outside of the rim ring here is to be understood to mean its outer surface serving to receive the tire, and the inner side corresponding to this to be the inner surface facing the rotational or axial axis of the vehicle wheel. The outer surface of the wheel dish is to be understood here as the visible from the outside after installation of the vehicle wheel on the visible surface of the wheel dish, as its inside standing thereof in the opposite direction, substantially perpendicular to the rotational or axial axis, pointing into the wheel inner surface of the wheel , The fiber-reinforced plastic coating according to the present embodiment may thus be mounted on the outside of the rim ring and wheel or on the inside of rim and wheel or on the outside of the rim and on the inside of the wheel or on the inside of the rim and on the outside of the wheel ,

The coating on substantially the entire outer and / or inner sides of the rim ring and the wheel allows due to the large plastic composite coating even further increase the strength of the vehicle and a further weight reduction, since the volume of the metal rim ring and / or the metal wheel according to the gain of the fiber reinforced plastic can / can be reduced. In addition, a large-area coating ensures a permanently strong connection between the metal material of the rim ring or the wheel disc and the fiber-reinforced plastic material.

According to a further advantageous embodiment of the invention, the fiber-reinforced plastic coating of the rim ring is formed integrally with the fiber-reinforced plastic coating of the wheel disc. This ensures an increased flow of force between the rim ring and the wheel disc, which reliably counteracts the high circumferential and cornering forces from the braking and acceleration moments or the direction changes during use of the vehicle wheel on the vehicle. Particularly preferably, the fiber-reinforced plastic coating can be applied in such an embodiment of the vehicle wheel at least on the outside of both the rim ring and the wheel disc. Alternatively or additionally, however, the fiber-reinforced plastic coating can also be applied on the inside of both the rim ring and the wheel disc.

To further increase the strength and to further simplify the manufacturability of the vehicle wheel of the rim ring according to a further advantageous embodiment of one piece, that is, from a single piece of metal material, for example by casting, be formed.

In this sense, according to a still further advantageous embodiment of the invention, the rim ring and the wheel disc together in one piece, that is, both of a single piece of metal material, for example by casting, be formed.

According to yet another advantageous embodiment of the invention, a first, seen in the axial direction of the vehicle wheel outer rim flange and a second, seen in the axial direction of the vehicle wheel inner rim flange for lateral guidance of the receivable tire are arranged on the rim ring. Here, at least one of the two rim flanges is formed integrally with the fiber-reinforced plastic coating of the fiber-reinforced plastic material. Thus, the fit of the tire which can be applied to the rim ring can be designed in the desired manner via the fiber-reinforced plastic material which can be shaped almost as desired with comparatively little effort. For example, the investment of a tire bead of a tire on the rim flange to ensure a safe lateral guidance of the rim ring mounted on the tire and also an airtight connection between the tire bead of the tire and the rim flange. In addition, by training at least one of the two rim flanges from the fiber-reinforced plastic material, abrasion between a tire applied to the rim ring and the metal material of the rim ring itself can be reduced because the fiber-reinforced plastic material can be made more resistant to abrasion and wear than the metal material.

It should be noted that also both rim flanges can be formed by the fiber-reinforced plastic material, which are then advantageously formed in one piece with the fiber-reinforced plastic coating.

Furthermore, according to a still further advantageous embodiment of the invention, one of the two rim flanges can be formed integrally with the fiber-reinforced plastic coating of the fiber-reinforced plastic material and the other of the two rim flanges can be formed integrally with the rim ring from its metal material.

According to a further aspect of the present invention, a method is provided for producing a vehicle wheel, in particular a vehicle wheel, according to one of the embodiments described above, wherein the method has at least the following steps:

• - Providing the vehicle wheel having a made of a metal material rim ring for receiving a tire and connected to the rim ring, made of a metal material wheel for detachable connection to a wheel of a vehicle;
• - Inserting the vehicle wheel in at least a part of a flat closed outside of both the rim ring and the wheel or at least a portion of a flat closed inside of both the rim ring and the wheel with a distance enclosing mold to one only by an inside of the mold and to form only through the outside or only through the inside of the rim ring and the Radschüssel limited cavity in which a fiber reinforcement matrix is arranged;
• - injecting a plastic material into the cavity;
• - curing the plastic material to form a fiber-reinforced plastic coating together with the fiber reinforcement matrix; and
• - Remove the vehicle wheel from the mold.

The particular advantage of the method according to the invention is the fact that the uncoated vehicle wheel, that is essentially the uncoated rim ring and the uncoated wheel bowl, can be used as a counterpart to the actual mold, since the cavity to be filled by the fiber-reinforced plastic material only by the Inside the mold and are formed by the rim ring and the wheel itself, which can significantly reduce the manufacturing cost and manufacturing costs, in particular the tool costs. In addition, since the cavity is formed in a portion of the rim ring and the wheel disc in which the rim ring and the wheel disc are closed flat, no additional provisions for closing possible openings in the rim ring and / or in the wheel disc during the injection of the plastic material into the cavity hold true.

It is to be understood that the steps of inserting, injecting, curing and demolding in this order can also be carried out several times in order to coat both the rim ring and the wheel disc at least partially with the fiber-reinforced plastic material, for example, to different areal closed areas of the outside - And / or inside of the rim ring and the wheel disc to be provided with the fiber-reinforced plastic material.

With regard to procedural definitions of terms and the effects and advantages of characteristics according to the method, reference is additionally made to the above explanations of mutatis mutandis definitions, effects and advantages with respect to the vehicle wheel according to the invention. Disclosures herein relating to the vehicle wheel according to the invention should be able to be used analogously to the definition of the method according to the invention, unless this is not expressly excluded herein. Likewise, disclosures herein with respect to the method according to the invention in a manner analogous to the definition of the vehicle wheel according to the invention can be used, unless this is also explicitly excluded. In this respect, a repetition of explanations analogous to the same features, their effects and advantages with regard to the inventive vehicle wheel disclosed herein and the inventive method for producing a vehicle wheel disclosed herein for the sake of a more compact description are largely dispensed with.

An advantageous embodiment of the invention further provides that the cavity as a single along the outside of the rim ring and along the outside of the wheel arch extending cavity or as a single along the inside of the rim ring and along the Inner side of the wheel bowl extending cavity is formed. This makes it possible to manufacture the entire fiber-reinforced plastic coating of the outside or the inside of the vehicle wheel in a single injection step of the plastic material, which can shorten the overall manufacturing process and reduce the manufacturing cost. In addition, the only cavity formed in this way allows a one-piece design of the entire fiber-reinforced plastic coating on the rim ring and the wheel disc.

According to a further advantageous embodiment of the invention, at least one passage opening is introduced after the removal of the vehicle wheel from the mold at least in the wheel disc. In this way, for example, at least one attachment opening can be introduced into the wheel dish, by means of which the vehicle wheel can later be detachably fastened to a wheel carrier of the vehicle during assembly on the vehicle by means of a screw bolt. Likewise, of course, other, other openings in the wheel, for example, brake ventilation openings, and / or in the rim ring can be introduced. In other words, in the method according to the invention, the rim ring and the wheel disc can preferably first be coated with the fiber-reinforced plastic material without any through-openings, with the previously described advantages of faster production of the vehicle wheel and a simpler shaping tool. Required through-holes can then be introduced after completion of the entire plastic coating in the rim ring and / or the wheel disc.

Further features and advantages of the invention will become apparent from the following description of non-limiting embodiments of the invention, which is explained in more detail below with reference to the drawing. In this drawing show schematically:

• 1 a cross-sectional view of an embodiment of a vehicle wheel according to the invention along its axial direction of extension after a particular manufacturing step,
• 2 a cross-sectional view of an embodiment of a mold for the preparation of the vehicle wheel 1 according to the invention along its axial extension direction,
• 3 a plan view of the mold 2 and
• 4 a cross-sectional view of the vehicle wheel 1 after another production step.

In the different figures, equivalent parts are always provided with the same reference numerals with respect to their function, so that these are usually described only once.

1 schematically illustrates a cross-sectional view of an embodiment of a vehicle wheel 1 according to the invention along its axial extension direction Y after a certain production step. The vehicle wheel 1 has a rim made of a metal material 2 for receiving a tire (not shown) and one on the rim ring 2 Tailored, made of a metal material wheel 3 for detachable connection to a wheel carrier (not shown) of a vehicle, also not shown. At the in 1 illustrated vehicle wheel 1 are the rim ring 2 and the wheel-dish 3 individually in one piece as well as jointly in one piece. However, this is not mandatory. The symmetry or rotation axis of the vehicle wheel 1 is in 1 with the reference number 4 characterized.

Furthermore is 1 to see that both the rim ring 2 as well as the wheel dish 3 in the embodiment shown substantially entirely with a fiber reinforced plastic material 5 are coated. At the in 1 illustrated vehicle wheel 1 is the fiber-reinforced plastic coating 5 on an outside 6 of the rim ring 2 as well as on an outside 7 the wheel-dish 3 applied. An inside 8th of the rim ring 2 is at the in 1 shown vehicle wheel 1 not with the fiber reinforced plastic material 5 coated, an inside 9 the wheel-dish 3 not either. Thus, that is in 1 illustrated vehicle wheel 1 or are his rim ring 2 and his wheel dish 3 not (not even partially) in the fiber-reinforced plastic coating 5 embedded. Rather, only the respective outer sides 6 and 7 flat with the fiber-reinforced plastic material 5 coated.

An additional advantage of the substantially full-surface coating of the wheel disc 3 on their outside 7 with the fiber reinforced plastic material 5 is to be seen in that the outside 7 the wheel-dish 3 forming a visible surface of the vehicle wheel 1 in a state installed on the vehicle, by means of the fiber-reinforced plastic material 5 visually appealing and can be designed almost arbitrarily. So can the outer surface 7 the wheel-dish 3 for example, with an appealing Carbon fiber optic when using a carbon fiber plastic material as a fiber reinforced plastic 5 be provided.

As 1 it can also be seen, is the fiber-reinforced plastic coating 5 altogether in one piece over the outsides 6 and 7 of the rim ring 2 and the wheel-dish 3 executed.

At the in 1 illustrated vehicle wheel 1 are on the rim ring 2 a first, in the axial direction Y of the vehicle wheel 1 seen Radäußeres rim flange 10 and a second, in the axial direction Y of the vehicle wheel 1 seen Radinneres rim flange 11 arranged for lateral guidance of the receivable tire (not shown). As in 1 is shown is in the illustrated embodiment of the vehicle wheel 1 the outer rim flange 10 one-piece with the fiber-reinforced plastic coating 5 from the fiber reinforced plastic material 5 formed, whereas the inner rim flange 11 in one piece with the rim ring 2 is formed from the metal material.

As 1 It can also be seen that are the with the fiber-reinforced plastic material 5 coated outsides 6 and 7 of the rim ring 2 or the wheel dish 3 flat closed outer surfaces. They point in the in 1 illustrated manufacturing stage of the vehicle 1 in their respective coated areas (still) no passage openings.

2 Fig. 2 schematically illustrates a cross-sectional view of an embodiment of a molding tool 12 for the production of the vehicle wheel 1 out 1 along its axial extension direction Y represents. 3 represents a plan view of the mold 12 out 2 represents.

This in 1 illustrated vehicle wheel 1 is in the representation of 2 in the mold 12 inserted.

As 3 can be seen, has the exemplary mold 12 a total of five moldings 13 . 14 . 15 . 16 and 17 on, in the sectional view of which 2 the moldings 14 . 16 and 17 can be seen. As in 2 can be seen further, is the molding 17 the outside 7 the wheel-dish 3 arranged enclosing at a distance. The moldings 14 and 16 (as well as the in 2 not recognizable moldings 13 and 15 ) are each the outside 6 of the rim ring 2 arranged enclosing at a distance. In this way, a cavity between only one inside of all moldings 13 . 14 . 15 . 16 and 17 and only the respective outer sides 6 and 7 of the rim ring 2 or the wheel dish 3 educated. rim 2 and wheel dish 3 in other words form the Gegenformstück to the moldings 13 . 14 . 15 . 16 and 17 , Other moldings, for example on the insides 8th and 9 fitting moldings of the mold are not required. In the in 2 illustrated manufacturing state of the vehicle wheel 1 is that of the moldings 13 . 14 . 15 . 16 and 17 and the rim ring 2 and the wheel-dish 3 formed cavity already from the plastic material 5 filled. This cavity thus corresponds to that of the in 2 illustrated plastic material 5 occupied volume.

After providing the vehicle wheel 1 initially without fiber-reinforced plastic coating 5 this gets into the mold 12 is inserted, so that the above-described cavity is formed, in the previously (unimpregnated) fiber reinforcement matrix is inserted. Subsequently, for example, via a in the molding 17 introduced injection channel 18 For example, in the context of a known resin injection process (also known as RTM or "Resin Transfer Molding"), the plastic material injected into the cavity. After complete filling of the cavity with plastic material, this is cured, so that together with the fiber reinforcement matrix, the fiber-reinforced plastic coating 5 forms. Finally, the thus coated vehicle wheel 1 from the mold 12 removed or removed from the mold.

Like now 4 , which is a cross-sectional view of the vehicle wheel 1 out 1 represents after a further manufacturing step, it can be seen, after removal of the vehicle wheel 1 from the tool 12 in the up to this manufacturing step (still) completely closed coating surface of the Radschüssel 3 including their fiber-reinforced plastic coating 5 several through holes 19 introduced, of which in the sectional view of 4 two are visible. The passage openings shown here 19 are mounting holes through which for releasably attaching the vehicle wheel 1 on a vehicle in a conventional manner in each case a bolt (not shown) is inserted, which is then releasably bolted to a wheel carrier (not shown) of the vehicle.

The above-described inventive vehicle wheel and its method of manufacture are not limited to the embodiments disclosed herein, but also encompass similar further embodiments resulting from technically meaningful further combinations of the features of both the vehicle wheel and the manufacturing method described herein.

In a preferred embodiment, the vehicle wheel according to the invention is attached to a motor vehicle, in particular, for example, on two-lane vehicles such as passenger cars, commercial vehicles, trucks and the like, but also on single-track vehicles we motorcycles used.
