Abstract

The invention relates to a device (3) for protecting a wheel rim (2) of a motor vehicle, wherein: an outer side of a rim flange (4) is covered by the device (3); the device (3) consists of a ring (5), the diameter of which is matched to that of the rim flange (4); and the ring (5) has a circumferential tongue (5.2) for fastening the device (3) to the rim flange (4), which tongue can be clamped between an inner side of the rim flange (4) and a side wall of a tyre (1). The device (3) is intended to be held securely on the wheel rim (1) even at very high speeds and correspondingly large forces acting on the device (3). No changes to the wheel rim (1) are necessary, and installation is simple. This is achieved in that the single ring (5) is produced from a hard material and has a continuous radial gap (6) and in that end faces (5.3) of the ring formed by the gap (6) can be connected by means of a clamping screw (8).

Description

Vorrichtung zum Schutz einer Felge eines Kraftfahrzeugs Device for protecting a rim of a motor vehicle
Die Erfindung betrifft eine Vorrichtung zum Schutz einer Felge eines Kraftfahrzeugs, wobei eine Außenseite eines Felgenhorns von der Vorrichtung bedeckt ist, wobei die Vorrichtung aus einem Ring besteht, dessen Durchmesser auf den des Felgenhorns abgestimmt ist, und wobei der Ring zum Befestigen der Vorrichtung an dem Felgenhorn eine umlaufende Zunge aufweist, die zwischen einer Innenseite des Felgenhorns und einer Seitenwand eines Reifens einklemmbar ist. The invention relates to a device for protecting a rim of a motor vehicle, an outside of a rim flange being covered by the device, the device consisting of a ring whose diameter is matched to that of the rim flange, and the ring for fastening the device to the Rim flange has a circumferential tongue which can be clamped between an inside of the rim flange and a side wall of a tire.
Solche Vorrichtungen sind an sich bekannt, z.B. unter dem Begriff Felgenschutzring. Sie werden insbesondere verwendet, um wertvolle Felgen wie z.B. sogenannte Leichtmetallfelgen vor mechanischen Schäden zu schützen. Solche Schäden können während einer Fahrt in Form von z.B. Kratzern durch Kontakt mit auf der Fahrbahn befindlichen Gegenständen oder insbesondere durch Bordsteinkanten zugefügt werden. Von den Beschädigungen sind besonders nach außen weisende Seiten von äußeren Felgenhörnern betroffen und wegen der guten Sichtbarkeit ärgerlich. Such devices are known per se, e.g. under the term rim protection ring. They are used in particular to protect valuable rims, such as so-called alloy rims, from mechanical damage. Such damage can be inflicted during a journey in the form of, for example, scratches from contact with objects on the road or, in particular, from curbs. The outward-facing sides of the outer rim flanges are particularly affected by the damage and are annoying because of the good visibility.
Felgen für Kraftfahrzeuge bestehen grundsätzlich aus einem scheibenförmigen Radkranz, auf dessen Umfang ein Felgenbett angeordnet ist. Das Felgenbett ist auf jeder Seite von einem Felgenhorn begrenzt. Ein Reifen ist an dem Felgenbett zwischen den Felgenhörnern eingespannt. Die Felge und der Reifen bilden ein Rad. Wheel rims for motor vehicles basically consist of a disc-shaped wheel rim, on the circumference of which a rim base is arranged. The rim bed is bordered on each side by a rim flange. A tire is clamped to the rim base between the rim flanges. The rim and tire form a wheel.
Aus der DE 20 2010 004 397 U1 ist ein Felgenschutzring bekannt, der klemmend zwischen Reifen und Felgenhorn montiert ist. Der Felgenschutzring bedeckt lediglich einen Teil einer Flanke des Reifens, während die Felge selbst von außen ungeschützt bleibt. Der Felgenschutzring kann nur zusammen mit dem Reifen auf der Felge montiert werden. A rim protection ring is known from DE 20 2010 004 397 U1, which is clamped between the tire and the rim flange. The rim protection ring only covers part of a sidewall of the tire, while the rim itself remains unprotected from the outside. The rim protection ring can only be mounted on the rim together with the tire.
Die DE 10 2012 015 516 A1 offenbart einen Felgenschutzring, der als Zierring ausgebildet ist. Er ist derart geformt, dass er aus einer Ebene der Felgenaußenseite nach außen herausragt, diese aber nicht bedeckt. Damit ist nur eine geringe Schutzwirkung für die Felge vorhanden. Der Felgenschutzring kann nur zusammen mit dem Reifen auf der Felge montiert werden. DE 10 2012 015 516 A1 discloses a rim protection ring which is designed as a decorative ring. It is shaped in such a way that it protrudes outwards from a plane on the outside of the rim, but does not cover it. This means that there is only a slight protective effect for the rim. The rim protection ring can only be mounted on the rim together with the tire.
Die DE 40 09 757 A1 beschreibt einen Felgenschutzring aus elastischem Material, der eine speziell geformte Umfangs- Nut aufweist. Mittels dieser Nut wird der Felgenschutzring auf einem Felgenhorn aufgeklemmt. Dies muss vor Montage des Reifens erfolgen. DE 40 09 757 A1 describes a rim protection ring made of elastic material, which has a specially shaped circumferential groove. The rim protection ring is clamped onto a rim flange using this groove. This must be done before mounting the tire.
Die EP 2 150 421 B1 offenbart einen Felgenschutzring aus elastischem Material mit einem inneren, dünn ausgebildeten Abschnitt und einem breit ausgebildeten Kopfabschnitt. Der innere Abschnitt ist zwischen einer Innenseite eines Felgenhorns und einem Reifen eingeklemmt, während der Kopfabschnitt das Felgenhorn außen überlappt und bei besonderer Ausbildung sich an das Felgenhorn anschmiegt. Der Felgenschutzring kann nur zusammen mit dem Reifen auf der Felge montiert werden. Aufgrund der Elastizität des Materials weicht der Kopfabschnitt bei größeren Belastungen aus und bietet keinen wirksamen Schutz. EP 2 150 421 B1 discloses a rim protection ring made of elastic material with an inner, thin section and a wide head section. The inner portion is sandwiched between an inside of a rim flange and a tire, while the head portion overlaps the rim flange on the outside and at particular Training clings to the rim flange. The rim protection ring can only be mounted on the rim together with the tire. Due to the elasticity of the material, the head section yields under greater loads and does not offer effective protection.
Ähnliches gilt für die US 2014/0167490 A1, wobei der Abschnitt zum Befestigen hier nicht durchgehend ist, sondern entsprechende Flügel aufweist. The same applies to US 2014/0167490 A1, where the section for fastening is not continuous here, but has corresponding wings.
Aus der US 2,964,357 A ist ein Zierring bekannt, der mittels federnden Klipsen an einem Felgenhorn befestigt ist. Die Befestigung erscheint relativ unsicher, weil der Zierring erst durch ein zweites Federelement an dem zugehörigen Klips befestigt ist. A decorative ring is known from US Pat. No. 2,964,357 A, which is fastened to a rim flange by means of resilient clips. The attachment appears relatively uncertain because the decorative ring is only attached to the associated clip by a second spring element.
Die US 2007/0290548 A1 beschreibt einen Ring zum Schützen einer Felge, der mittels Schrauben an dem Felgenhorn festgeklemmt ist. US 2007/0290548 A1 describes a ring for protecting a rim, which is clamped to the rim flange by means of screws.
Aus der WO 2005/009761 A1 ist ein Felgenschutzring bekannt, der außen auf einem Felgenhorn mittels einer Klammer befestigbar ist. Der Felgenschutzring kann bei radialer Belastung relativ leicht von der Felge abspringen. A rim protection ring is known from WO 2005/009761 A1, which can be attached to the outside of a rim flange by means of a clamp. The rim protection ring can jump off the rim relatively easily under radial load.

Die DE 10 2019 107 128 B3, von der die Erfindung ausgeht, offenbart eine Vorrichtung zum Schutz einer Felge, die aus zwei Ringen gebildet ist. Ein erster der Ringe weist eine umlaufende Zunge und einen durchgehenden radialen Spalt auf. Die Zunge gewährleistet einen sicheren Halt der Vorrichtung an der Felge und somit an dem Rad, weil ein innerer Durchmesser der Zunge kleiner ist als ein größter Durchmesser des Felgenhorns; die Montage des ersten Rings wird durch den Spalt ermöglicht, der ein kurzfristiges elastisches Öffnen des ersten Rings und somit sein Stülpen über das Felgenhorn erlaubt. Ein unbeabsichtigtes Öffnen des Spalts wird durch einen zweiten der Ringe verhindert, der lösbar an den ersten Ring befestigt ist. Die Ringe sind aus hartem Material gefertigt. Es ist die Aufgabe der Erfindung, eine Vorrichtung zum Schutz einer Felge zu schaffen, die auch bei sehr hohen Geschwindigkeiten und entsprechend großen auf die Vorrichtung wirkenden Kräften sicher an der Felge gehalten ist. Hierbei sollen an der Felge keine Änderungen erforderlich sein. DE 10 2019 107 128 B3, on which the invention is based, discloses a device for protecting a wheel rim, which is formed from two rings. A first of the rings has a circumferential tongue and a continuous radial gap. The tongue ensures that the device is held securely on the rim and thus on the wheel, because an inner diameter of the tongue is smaller than a maximum diameter of the rim flange; the assembly of the first ring is made possible by the gap, which allows a short-term elastic opening of the first ring and thus its slipping over the rim flange. Accidental opening of the gap is prevented by a second of the rings being detachably attached to the first ring. The rings are made of hard material. It is the object of the invention to create a device for protecting a wheel rim, which is held securely on the wheel rim even at very high speeds and correspondingly large forces acting on the device. No changes should be necessary to the rim.
Die Aufgabe ist durch die Merkmale des Anspruchs 1 gelöst. Der einzige Ring ist aus einem harten Material gefertigt, weist einen durchgehenden radialen Spalt auf, und durch den Spalt gebildete Stirnseiten des Rings sind mittels einer Spannschraube verbindbar. The object is solved by the features of claim 1. The single ring is made of a hard material, has a continuous radial gap, and end faces of the ring formed by the gap can be connected by means of a clamping screw.
Verbinden bedeutet hierbei nicht, dass die Stirnseiten nach dem Verbinden in unmittelbarem Kontakt sein müssen. In den meisten Fällen werden die Stirnseiten bei montierter Vorrichtung einen Abstand aufweisen, der mittels der Spannschraube überbrückt ist. Joining does not mean that the end faces have to be in direct contact after joining. In most cases, when the device is installed, the end faces will be at a distance that is bridged by the clamping screw.
Der Ring und damit die Vorrichtung ist aus hartem Material gefertigt. Hierdurch ist eine hohe Stabilität sowie Haltbarkeit und damit auch ein guter Schutz von Felge und Reifen gewährleistet. Ein „Flattern“ und dessen Amplitute während einer schnellen Drehung des Rades wie bei einer Fahrt des Kraftfahrzeugs mit hoher Geschwindigkeit sind zumindest minimiert.The ring and thus the device is made of hard material. This ensures high stability and durability and thus good protection of rims and tires. A "flutter" and its amplitude during a rapid rotation of the wheel, such as when the motor vehicle is traveling at high speed, are at least minimized.
Der Spalt erlaubt eine Montage beziehungsweise Demontage der Vorrichtung. The gap allows assembly or disassembly of the device.
Das Verbinden der Stirnseiten mittels einer Spannschraube gewährleistet den sicheren Halt der montierten Vorrichtung an der Felge, weil so ein praktisch geschlossener Ring entsteht, der nur nach Lösen der Spannschraube wieder von der Felge entfernt werden kann. Hierbei können Fertigungstoleranzen sowohl der Felge als auch der Vorrichtung durch Variieren einer Spaltweite des Spalts ausgeglichen werden, so dass der Ring zumindest spielfrei an dem Felgenhorn montiert werden kann; gegebenenfalls kann auch eine Vorspannung des Rings auf dem Felgenhorn eingestellt werden. Damit sind die Vorrichtung und die Felge ideal aneinander angepasst, so dass ein fester und zentrierter Halt des Rings an dem Felgenhorn gewährleistet ist. Weiterhin verhindert die spielfreie Montage ein gegenseitiges Beschädigen von Felge und Vorrichtung. Connecting the end faces using a clamping screw ensures that the mounted device is held securely on the rim, because this creates a practically closed ring that can only be removed from the rim again after loosening the clamping screw. Here, manufacturing tolerances of both the rim and the device can be compensated for by varying a gap width of the gap, so that the ring can be mounted on the rim flange at least without play; if necessary, a pre-tension of the ring on the rim flange can also be adjusted. The device and the rim are thus ideally adapted to each other, so that a firm and centered hold of the ring on the rim flange is guaranteed. Furthermore, the play-free assembly prevents mutual damage to the rim and the device.
An der Felge sind für die Befestigung der Vorrichtung keine Änderungen erforderlich. Die Felge bleibt im Originalzustand erhalten und behält ihren Wert. No modifications are required to the rim to attach the device. The rim remains in its original condition and retains its value.
Der Ring bestimmt wesentlich das sichtbare Erscheinungsbild der Felge mit und beeinflusst so das Aussehen des gesamten Kraftfahrzeugs positiv. Ein Design des Ringes wie z.B. Farbgestaltung und/oder Musterung ist weitgehend frei wählbar. An dem Ring können auch Zierelemente wie z.B. Schrauben befestigt oder imitiert werden. The ring significantly determines the visible appearance of the rim and thus has a positive influence on the appearance of the entire vehicle. A design of the ring, such as color and/or pattern, is largely freely selectable. Decorative elements such as screws can also be attached or imitated to the ring.
Die Unteransprüche betreffen die vorteilhafte Ausgestaltung der Erfindung. In einer Ausgestaltung sind die Ringe aus einem Leichtmetall oder einer Leichtmetalllegierung gefertigt. Die Vorrichtung kann insgesamt leichtgewichtig gefertigt werden bei trotzdem großer Festigkeit. The dependent claims relate to the advantageous embodiment of the invention. In one embodiment, the rings are made from a light metal or a light metal alloy. The device can be made lightweight overall while still being very strong.
In einer alternativen Ausgestaltung sind die Ringe aus einem Carbon- Verbundmaterial gefertigt. Hierdurch wird weiter Gewicht eingespart. In an alternative embodiment, the rings are made from a carbon composite material. This further saves weight.
In einer weiteren Ausgestaltung weist der Spalt in einem ungespannten Zustand des Rings eine Weite von 5 mm bis 20 mm auf. Der ungespannte Zustand bedeutet hierbei, dass keine Kräfte zum Öffnen oder Schließen des Spalts Wirken. Die genannte Weite des Spalts erleichtert die Montage beziehungsweise Demontage und erlaubt den Ausgleich auch größerer Fertigungstoleranzen. In a further embodiment, the gap has a width of 5 mm to 20 mm when the ring is in an unstressed state. The relaxed state means that no forces are acting to open or close the gap. Said width of the gap facilitates assembly or disassembly and also allows greater manufacturing tolerances to be compensated for.
In einer weiteren Ausgestaltung weist die Spannschraube unterschiedliche Nenndurchmesser ihrer Gewinde auf. Dies erleichtert die Montage der Vorrichtung, weil eine falsche Ausrichtung der Spannschraube zu den Stirnseiten sofort bemerkt wird. In a further embodiment, the clamping screw has different nominal diameters for its threads. This simplifies the assembly of the device because incorrect alignment of the clamping screw to the end faces is noticed immediately.
In einer weiteren Ausgestaltung ist der Spalt mittels einer Blende abdeckbar. Dies verbessert die optische Wirkung der Vorrichtung, vermindert die Ansammlung von Schmutz und kann so die Demontage erleichtern. In a further embodiment, the gap can be covered by a screen. This improves the visual appeal of the device, reduces dirt accumulation and can thus facilitate disassembly.
Alternativ zu der Blende ist an einer nach außen weisenden Seite des Rings ein Zierring befestigbar. Hierbei deckt der Zierring einen vorbestimmten Teil der Felge und gegebenenfalls einen Teil einer Außenflanke des Reifens ab. Hierdurch wird die Schutzwirkung insgesamt erhöht. Außerdem ist ein Design des Rades insgesamt weiter variierbar. As an alternative to the panel, a decorative ring can be fastened to an outwardly pointing side of the ring. In this case, the decorative ring covers a predetermined part of the rim and optionally part of an outer sidewall of the tire. This increases the overall protective effect. In addition, a design of the wheel as a whole can be further varied.
Bevorzugt umfasst die Blende beziehungsweise der Zierring ein Mittel zur Sicherung der Spannschraube gegen Verdrehen. Das Mittel ist z.B. als Dorn, der mit einer entsprechenden Bohrung in der Spannschraube zusammenwirkt, oder als Klammer ausgebildet. Hierdurch wird verhindert, dass sich die Spannschraube unbeabsichtigt löst und dadurch die Vorrichtung instabil wird oder sogar von der Felge abspringen kann. The screen or the decorative ring preferably includes a means for securing the clamping screw against twisting. The means is designed, for example, as a mandrel that interacts with a corresponding bore in the clamping screw, or as a clamp. This prevents the clamping screw from loosening unintentionally, which would cause the device to become unstable or even jump off the rim.

Wie aus den Figuren 1 bis 4 ersichtlich umfasst ein Rad eines Kraftfahrzeugs (Kfz) einen Reifen 1, der auf einer Felge 2 in üblicher Weise montiert ist. An einer Außenseite des Rades, das ist die kreisförmige Fläche, die bei dem an dem Kraftfahrzeug befestigten Rad ohne Weiteres sichtbar ist, ist eine Vorrichtung 3 zum Schutz der Felge 2 angeordnet. As can be seen from FIGS. 1 to 4, a wheel of a motor vehicle (motor vehicle) comprises a tire 1 which is mounted on a rim 2 in the usual way. On an outside of A device 3 for protecting the rim 2 is arranged on the wheel, which is the circular area which is readily visible when the wheel is attached to the motor vehicle.
Die Felge 2 umfasst wie üblich eine Felgenscheibe, an deren Außenumfang ein Felgenbett angeordnet ist. Jede Umfangsseite des Felgenbetts ist von einem Felgenhorn 4 begrenzt. Der auf die Felge 2 fertig montierte Reifen 1 ist mit seinen Seitenwänden im Bereich seiner Wülste zwischen den Felgenhörnern 4 eingespannt. An dem Reifen 1 kann außen, das heißt bei montiertem Rad sichtbar, an der Seitenwand in der Nähe des Felgenhorns 4 eine ringförmige Verdickung aus Gummi ausgebildet sein. As usual, the rim 2 comprises a rim disk, on the outer circumference of which a rim bed is arranged. Each peripheral side of the rim well is delimited by a rim flange 4 . The tire 1 that has been completely mounted on the rim 2 is clamped with its side walls in the region of its beads between the rim flanges 4 . On the outside of the tire 1, that is to say visible when the wheel is mounted, an annular thickening made of rubber can be formed on the side wall in the vicinity of the rim flange 4.
Die Vorrichtung 3 besteht aus einem einzigen Ring 5, dessen mittlerer Durchmesser an den Nenndurchmesser der Felge 2 angepasst ist. Der Ring 5 ist an einem äußeren der Felgenhörner 4 und nach außen weisend angeordnet. The device 3 consists of a single ring 5 whose mean diameter is adapted to the nominal diameter of the rim 2 . The ring 5 is arranged on an outer one of the rim flanges 4 and points outwards.
Der Ring 5 ist in der Figur 3 deutlicher dargestellt. Er ist an einer einzigen Stelle seines Umfangs radial durchtrennt (damit ist der Ring 5 genaugenommen ein Ringabschnitt über z.B. ca. 350° bis ca. 359°) und bildet so einen Spalt 6. Infolge der Durchtrennung sind an der Trennstelle zwei Stirnseiten 5.3 gebildet, die den Spalt 6 begrenzen. The ring 5 is shown more clearly in FIG. It is severed radially at a single point on its circumference (therefore the ring 5 is, strictly speaking, a ring section over, for example, approx. 350° to approx. 359°) and thus forms a gap 6. As a result of the separation, two end faces 5.3 are formed at the separation point. which limit the gap 6.
Der Ring weist einen Grundkörper 5.1 auf, der im Querschnitt im Wesentlichen rechteckig ist. The ring has a base body 5.1 which is essentially rectangular in cross section.
In einem nach der Figur 3 oberen Endbereich einer ersten Längsseite des Grundkörpers 5.1 ist einstückig mit diesem eine Zunge 5.2 angeformt. Die Zunge 5.2 erstreckt sich über den Umfang des ersten Rings 5 und weist eine Krümmung auf, deren konkave Seite zu dem Grundkörper 5.1 weist. Eine konkave Begrenzung der Zunge 5.2 ist aus einem Kreissegment und einer Geraden gebildet und an eine Form eines zugeordneten Teils des Felgenhorns 4 angepasst. Die Zunge 5.2 verjüngt sich zu ihrem freien Ende hin, das bedeutet, ein Radius des Kreissegments einer konvexen Begrenzung ist größer als ein Radius der konkaven Begrenzung der Zunge 5.2; das freie Ende ist halbkreisförmig gerundet. Die konvexe Begrenzung begrenzt in Verlängerung ebenfalls eine zugeordnete obere, radial äußere Breitseite des Grundkörpers 5.1. In an upper end area according to FIG. 3 of a first longitudinal side of the base body 5.1, a tongue 5.2 is integrally formed therewith. The tongue 5.2 extends over the circumference of the first ring 5 and has a curvature whose concave side faces the base body 5.1. A concave delimitation of the tongue 5.2 is formed from a circle segment and a straight line and is adapted to a shape of an associated part of the rim flange 4. The tongue 5.2 tapers towards its free end, which means that a radius of the circular segment of a convex boundary is larger than a radius of the concave boundary of the tongue 5.2; the free end is rounded in a semicircle. The extension of the convex delimitation likewise delimits an associated upper, radially outer broad side of the base body 5.1.
In diese radial äußere Breitseite des Grundkörpers 5.1 kann wie gezeigt eine z.B. V-förmige Nut 5.4 eingelassen sein. As shown, a V-shaped groove 5.4, for example, can be embedded in this radially outer broad side of the base body 5.1.
In jede der Stirnseiten 5.3 und senkrecht zu dieser ist eine erste Sackbohrung 7 eingelassen, wie aus der Figur 4 besonders gut ersichtlich ist. Die beiden ersten Sackbohrungen 7 weisen vorzugsweise unterschiedliche Durchmesser auf. In jeder der ersten Sackbohrungen 7 ist ein nicht explizit dargestelltes Innengewinde angeordnet, wobei die beiden Innengewinde gegensinnig sind. Zwischen den Stirnseiten 5.3 und in die Innengewinde der ersten Sackbohrungen 7 eingreifend ist eine Spannschraube 8 angeordnet. Diese weist wie üblich zwei gegensinnige Außengewinde (nicht dargestellt) auf, die passend zu den Innengewinden der ersten Sackbohrungen 7 unterschiedliche Durchmesser aufweisen. Zwischen den Außengewinden ist ein Zwischenteil ausgebildet, das kein Gewinde und einen größeren Umhüllungs- Durchmesser als das größere der Außengewinde aufweist. In das Zwischenteil sind zwei rechtwinklig zueinander angeordnete radiale Durchgangsbohrungen eingelassen; alternativ zu den Durchgangsbohrungen ist das Zwischenteil sechskantig geformt (nicht dargestellt), so dass es mit einem passenden Maulschlüssel axial gedreht werden kann. A first blind hole 7 is embedded in each of the end faces 5.3 and perpendicular thereto, as can be seen particularly well from FIG. The first two blind holes 7 preferably have different diameters. In each of the first blind bores 7 there is an internal thread which is not explicitly shown, the two internal threads being in opposite directions. Between the end faces 5.3 and engaging in the internal threads of the first blind bores 7, a clamping screw 8 is arranged. As usual, this has two external threads in opposite directions (not shown), which have different diameters to match the internal threads of the first blind bores 7 . Between the male threads is formed an intermediate portion which is unthreaded and has a larger cladding diameter than the larger of the male threads. Two radial through bores arranged at right angles to one another are let into the intermediate part; as an alternative to the through-holes, the intermediate part has a hexagonal shape (not shown), so that it can be turned axially with a suitable open-end wrench.
Der Ring 5 ist aus hartem Material wie z.B. Leichtmetalllegierung oder Karbon- Verbundmaterial gefertigt. Die Spannschraube 8 besteht aus Stahl. The ring 5 is made of hard material such as light alloy or carbon composite material. The clamping screw 8 is made of steel.
In einer bevorzugten Ausführung ist der Spalt 6 außen mittels einer abnehmbaren Blende 9 abgedeckt, die in der Figur 5 als Detail dargestellt ist. Die Blende 9 hat die Form eines Ringabschnitts, dessen mittlerer Radius weitgehend dem des Rings 5 entspricht. Eine Länge der Blende 9 beträgt z.B. 3 cm bis 6 cm. Die Blende 9 weist einen U-förmigen Querschnitt auf, wobei montiert Schenkel des U die Breitseiten des Grundkörpers 5.1 zumindest teilweise umschließen. Längsenden der Blende 9 können wie in der Figur 5 gezeigt halbkreisförmig gerundet sein. In Längsrichtung zentrisch sowie näher zu der konvexen Seite versetzt ist ein Mittel zur Sicherung der Spannschraube 8 gegen Verdrehen angeordnet, hier in Form eines Dorns 10 mit kreisförmigem Querschnitt. Der Dorn 10 ragt senkrecht aus einer inneren Fläche der Blende 9 mit einer Länge, die größer ist als eine Höhe der Schenkel des U und hierbei mindestens so groß, dass der Dorn 10 bei montierter Blende 9 eine der Durchgangsbohrungen der Spannschraube 8 vollständig durchdringt. In a preferred embodiment, the gap 6 is covered on the outside by a removable panel 9, which is shown in detail in FIG. The screen 9 has the shape of a ring section whose mean radius largely corresponds to that of the ring 5 . A length of the diaphragm 9 is 3 cm to 6 cm, for example. The screen 9 has a U-shaped cross section, with the assembled legs of the U enclosing the broad sides of the base body 5.1 at least partially. As shown in FIG. 5, the longitudinal ends of the screen 9 can be rounded in the shape of a semicircle. Arranged centrally in the longitudinal direction and offset closer to the convex side is a means for securing the clamping screw 8 against twisting, here in the form of a mandrel 10 with a circular cross section. The mandrel 10 protrudes perpendicularly from an inner surface of the panel 9 with a length that is greater than the height of the legs of the U and at least so large that the mandrel 10 completely penetrates one of the through holes of the clamping screw 8 when the panel 9 is mounted.
Radial vor und hinter dem Dorn 10 ist jeweils eine Rastfeder 11 so angeordnet, dass das Paar der Rastfedern 11 klemmend an dem Zwischenteil der Spannschraube 8 angreift. Damit ist die Blende 9 rastend und lösbar an dem Ring 5 gehalten. Zugewandte Seiten der Rastfedern 11 sind entsprechend dem Zwischenteil geformt, so dass bei dem sechskantigen Zwischenteil eine Sicherung der Spannschraube 8 gegen Verdrehen gesichert ist. A detent spring 11 is arranged radially in front of and behind the mandrel 10 in such a way that the pair of detent springs 11 grips the intermediate part of the clamping screw 8 in a clamping manner. The screen 9 is thus held on the ring 5 in a latching and detachable manner. Facing sides of the detent springs 11 are shaped according to the intermediate part, so that in the case of the hexagonal intermediate part, the clamping screw 8 is secured against twisting.
Eine Länge der Rastfedern 11 ist maximal so groß wie die axiale Länge des Zwischenteils.A maximum length of the detent springs 11 is as great as the axial length of the intermediate part.
Eine im montierten Zustand sichtbare, also äußere Fläche der Blende 9 kann eine Verzierung wie z.B. ein Logo oder eine Marke aufweisen. A surface of the panel 9 that is visible in the installed state, that is to say an outer surface, can have a decoration such as a logo or a trademark.
Gleichmäßig über den Umfang des Rings 5 verteilt können in die Außenseite des Grundkörpers 5.1 mehrere zweite Sack- oder Durchgangsbohrungen mit Innengewinden eingelassen sein. Wie die Figur 6 zeigt, ist alternativ zu der Anordnung der Blende 9 die Außenseite des Rings 5 mit einem Zierring 12 bedeckt, in dem zu den oben genannten Bohrungen korrespondierende dritte Durchgangsbohrungen angeordnet sind. Der Zierring 12 ist an den Durchmesser der Felge 2 angepasst und ist im Wesentlichen eben mit Ausnahme eines kurzen Winkelstücks, das an seinem radial äußeren Rand ausgebildet ist. Das Winkelstück ist wenige mm breit und weist bei der fertig montierten Vorrichtung 3 rechtwinklig so nach innen, dass es kein oder nur ein geringes Spiel zu der radial äußeren Breitseite des Grundkörpers 5.1 aufweist. Der Zierring 12 ist z.B. mittels Kopfschrauben an dem Ring 5 befestigt; alternativ ist das Winkelstück etwas breiter und weist eine Rastnase auf, die in die Nut 5.4 einrastbar ist. Der Zierring 12 kann unterschiedlichste Designs aufweisen und ist einfach austauschbar. Distributed evenly over the circumference of the ring 5, several second blind holes or through-holes with internal threads can be let into the outside of the base body 5.1. As FIG. 6 shows, as an alternative to the arrangement of the panel 9, the outside of the ring 5 is covered with a decorative ring 12 in which the above-mentioned bores corresponding third through holes are arranged. The trim ring 12 is matched to the diameter of the rim 2 and is substantially planar except for a short elbow formed at its radially outer edge. The angle piece is a few mm wide and, in the fully assembled device 3, points inwards at right angles in such a way that it has little or no play with respect to the radially outer broad side of the base body 5.1. The decorative ring 12 is fixed to the ring 5, for example by means of cap screws; alternatively, the angle piece is somewhat wider and has a locking lug that can be locked in the groove 5.4. The decorative ring 12 can have a wide variety of designs and can be easily replaced.
Zur Montage der Vorrichtung 3 auf ein Rad wird zunächst der Ring 5 durch entsprechendes Drehen der Spannschraube 8 so weit geöffnet, dass die Zunge 5.2 über das Felgenhorn 4 gestülpt werden kann. Die Spannschraube 8 soll hierbei nicht vollständig aus den ersten Sackbohrungen 7 entfernt werden, so dass wenige Gewindegänge hierin gehalten sind. Durch gegensinniges Drehen der Spannschraube 8 wird der Duchmesser der Vorrichtung so weit verkleinert, dass sich die Zunge 5.2 eng mit leichter Vorspannung an das Felgenhorn 4 anschmiegt. Schließlich wird das Rad an dem Kraftfahrzeug befestigt. Die Vorrichtung ist sicher an dem Rad befestigt: einerseits durch den größeren Außen- Durchmesser des Felgenhorns 4 gegenüber dem kleinsten Durchmesser der Zunge 5.2 und andererseits durch Einklemmen der Zunge 5.2 zwischen dem Felgenhorn 4 und dem Reifen 1. To mount the device 3 on a wheel, the ring 5 is first opened by turning the clamping screw 8 accordingly so that the tongue 5.2 can be slipped over the rim flange 4. The clamping screw 8 should not be completely removed from the first blind bores 7, so that a few threads are held therein. By turning the clamping screw 8 in the opposite direction, the diameter of the device is reduced to such an extent that the tongue 5.2 nestles closely against the rim flange 4 with a slight pretension. Finally, the wheel is attached to the motor vehicle. The device is securely attached to the wheel: on the one hand by the larger outer diameter of the rim flange 4 compared to the smallest diameter of the tongue 5.2 and on the other hand by clamping the tongue 5.2 between the rim flange 4 and the tire 1.
Gegebenenfalls wird die Blende 9 oder alternativ der Zierring 12 außen an dem Grundkörper 5.1 befestigt. If necessary, the panel 9 or alternatively the decorative ring 12 is attached to the outside of the base body 5.1.
Zur Demontage der Vorrichtung 3 von dem Rad - z.B. zum Austausch der Vorrichtung oder bei einem Reifenwechsel - wird gegebenenfalls die Blende 9 oder der Zierring 12 von dem Grundkörper 5.1 abgenommen. Der Ring 5 wird durch entsprechendes Drehen der Spannschraube 8 so weit geöffnet, dass die Zunge 5.2 über das Felgenhorn 4 von diesem weggezogen und so die Vorrichtung 3 von dem Rad abgenommen werden kann. To dismantle the device 3 from the wheel - for example, to replace the device or when changing a tire - the panel 9 or the decorative ring 12 is removed from the base body 5.1 if necessary. The ring 5 is opened by turning the clamping screw 8 accordingly so that the tongue 5.2 is pulled away from the rim flange 4 and the device 3 can thus be removed from the wheel.
