Spike für FahrzeugreifenSpike for vehicle tires
Die Erfindung betrifft einen Spike für die Lauffläche eines Fahrzeugreifens nach dem Oberbegriff des Anspruchs 1.The invention relates to a spike for the tread of a vehicle tire according to the preamble of claim 1.
Spikes für die Lauffläche eines Fahrzeugreifens, insbesondere eines Winterreifens, sind in verschiedensten Ausführungen bekannt.Spikes for the tread of a vehicle tire, in particular a winter tire, are known in various designs.
Alle Spikes bestehen aus einem Körper, der wenigstens teilweise in die Lauffläche des Fahrzeugreifens einbringbar ist. Hierzu sind in der Lauffläche des Fahrzeugreifens üblicherweise an vorgegebener Stelle Löcher vorgesehen, in welche die Spikes mit großer Kraft hineingedrückt werden können. Da sich die Lauffläche eines Fahrzeugreifens üblicherweise aus einem elastischen Material, insbesondere aus Gummi, zusammensetzt, wer- den die Löcher beim Einbringen der Spikes derart reversibel gedehnt, dass das elastische Material nach dem Einbringen der Spikes vollflächig auf den Spikes aufliegt und die Spikes in der Lauffläche des Fahrzeugreifens hält.All spikes consist of a body that can be at least partially inserted into the tread of the vehicle tire. For this purpose, holes are usually provided in the tread of the vehicle tire at a predetermined location, into which the spikes can be pressed with great force. Since the tread of a vehicle tire is usually composed of an elastic material, in particular rubber, the holes are expanded so reversibly when the spikes are inserted that the elastic material rests on the spikes over the entire surface after the spikes have been introduced and the spikes in the Tread of the vehicle tire holds.
Bekannte Spikes sind beispielsweise in der EP 1 199 193 AI beschrieben. Der Körper die- ser Spikes umfasst eine plattenförmige Wurzel, mit welcher der Spike in der Nähe der oberen Gürtellage im Fahrzeugreifen verankert ist und die den größten Durchmesser der Spiketeile aufweist. Die Wurzel ist üblicherweise über einen Halsteil mit einem Spikeoberteil verbunden, wobei der Spikeoberteil üblicherweise aus einem dickeren Spiketeil und einer demgegenüber verjüngten Spikespitze besteht, welche üblicherweise aus der Lauffläche herausragt. Bei der Spikespitze kann es sich um einen Stift handeln, der imKnown spikes are described for example in EP 1 199 193 AI. The body of this spike comprises a plate-shaped root, with which the spike is anchored near the upper belt layer in the vehicle tire and which has the largest diameter of the spike parts. The root is usually connected to a spike upper part via a neck part, wherein the spike upper part usually consists of a thicker spike part and a spike tip which is tapered in relation thereto and which usually protrudes from the running surface. The spike tip can be a pen that is in the
Spiketeil eingebettet ist. Alle Teile des in die Lauffläche eingebrachten Körpers sind zylin- derförmig, besitzen also zwei Grundflächen, die parallel, eben, kongruent und durch eine Mantelfläche miteinander verbunden sind. Die Grundflächen können hierbei unterschiedli ehe Formen, beispielsweise die eines Kreises, eines Dreiecks, eines Quadrats, eines Rechtecks oder eines Ovals, aufweisen.Spike part is embedded. All parts of the body introduced into the running surface are cylindrical, that is to say they have two base surfaces which are parallel, flat, congruent and connected to one another by a lateral surface. The base areas can differ before having shapes such as a circle, a triangle, a square, a rectangle, or an oval.
Nachteilig an den bekannten Spikes ist, dass diese bei Benutzung des Fahrzeugreifens auf einer Schnee- oder Eisfläche oder auf einer Fläche mit Schmutzpartikeln trotz ihrer Wurzelverankerung relativ schnell aus der Lauffläche des Fahrzeugreifens herausfallen oder zumindest relativ große Bewegungen in der Lauffläche vollführen. Dies fuhrt nachteilig dazu, dass die gewünschte Wirkung der Spikes relativ schnell verloren geht und der mit den Spikes versehene Fahrzeugreifen nur eine geringe Lebensdauer hat.A disadvantage of the known spikes is that when the vehicle tire is used on a snow or ice surface or on a surface with dirt particles, despite their root anchoring, they fall out relatively quickly from the tread of the vehicle tire or at least perform relatively large movements in the tread. This leads disadvantageously to the fact that the desired effect of the spikes is lost relatively quickly and that the vehicle tire provided with the spikes has a short lifespan.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Spike bereitzustellen, der eine bessere Haftung in der Lauffläche des Fahrzeugreifens aufweist.Based on this prior art, the object of the invention is to provide a spike which has better grip in the tread of the vehicle tire.
Diese Aufgabe wird bei einem Spike für die Lauffläche eines Fahrzeugreifens, insbesondere eines Winterreifens, mit einem Körper, der wenigstens teilweise in die Lauffläche des Fahrzeugreifens einbringbar ist, durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Weiterbildungen und vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved in the case of a spike for the tread of a vehicle tire, in particular a winter tire, with a body which can be at least partially inserted into the tread of the vehicle tire by the features of the characterizing part of claim 1. Further developments and advantageous refinements of the invention result from the subclaims.
Der Erfindung liegt die Erkenntnis zugrunde, dass bei Benutzung der mit herkömmlichen Spikes versehenen Fahrzeugreifen auf einem schnee-, eis- und oder schmutzhaltigen Untergrund Schnee-, Eis- und oder Schmutzpartikel in den Raum zwischen dem Spike und dem elastischen Material der Lauffläche gelangen. Dies führt dazu, dass das elastische Material der Lauffläche vom Spüce weggedrängt wird. Die im Zwischenraum befindlichen Partikel bilden dann quasi eine Art Gleitmittel und setzen die Haftung der Spikes in der Lauffläche derart herab, dass diese aus der Lauffläche herausfallen oder sich stark bewegen.The invention is based on the knowledge that when using the vehicle tires provided with conventional spikes, snow, ice and or dirt particles get into the space between the spike and the elastic material of the tread on a snow, ice and or dirt-containing surface. This leads to the elastic material of the tread being pushed away from the sink. The particles in the gap then form a kind of lubricant and reduce the adhesion of the spikes in the tread such that they fall out of the tread or move strongly.
Dadurch, dass erfϊndungsgemäß der in die Lauffläche einbringbare Teil des Körpers wenigstens teilweise kegel- oder kegelstumpfförmig ausgebildet ist, wobei die Grundfläche des kegel- oder kegelstumpfföπriigen Teils des in die Lauffläche eingebrachten Körpers ins Innere des Fahrzeugreifens weist, wird auf überraschend einfache Weise eine bessere Haftung der Spikes in der Lauffläche erreicht. Insbesondere wird auch die Bewegung der Spikes innerhalb der Lauffläche verringert, so dass insgesamt die Haltbarkeit und die Lebensdauer des Fahrzeugreifens erhöht wird. Zudem wirkt vorteilhaft eine niedrigere Spike- kraft auf den Untergrund, so dass weniger Straßenabrieb entsteht.Characterized in that, according to the invention, the part of the body which can be introduced into the running surface is at least partially conical or frustoconical, the base surface of the conical or frustoconical part of the body introduced into the running surface points inside the vehicle tire, better adhesion of the spikes in the tread is achieved in a surprisingly simple manner. In particular, the movement of the spikes within the tread is also reduced, so that the durability and the service life of the vehicle tire are increased overall. In addition, a lower spike force has an advantageous effect on the ground, so that less road abrasion occurs.
Dies ist auf die geänderte Kraftverteilung des auf den kegel- oder kegelsürmpfföπriigen Teil des Spikekörpers wirkenden elastischen Materials der Lauffläche zurückzuführen. Es wirken zwei Kraftkomponenten, nämlich einerseits eine vertikale Kraft F(S) x cos α und andererseits eine radial Kraft F(S) x sin α, wobei die daraus resultierende vertikale Kraft F(STOTAL) x cos α den Spike ins Innere des Fahrzeugreifens drückt. Eine derartige vertikale Kraft ist bei den herkömmlichen in die Lauffläche des Fahrzeugreifens eingebrachten Spikes nicht vorhanden.This is due to the change in the force distribution of the elastic material of the tread, which acts on the part of the spike body that is conical or conical. Two force components act, namely on the one hand a vertical force F (S) x cos α and on the other hand a radial force F (S) x sin α, the resulting vertical force F (S TOTAL ) x cos α causing the spike into the interior of the vehicle tire suppressed. Such a vertical force is not present in the conventional spikes introduced into the tread of the vehicle tire.
Als Winkel α wird der Winkel zwischen Mantelfläche und Grundfläche des kegel- oder kegelstumpfförmigen Teils verstanden, welcher zwischen 1 und 89°, vorzugsweise zwischen 20 und 70°, besonders bevorzugt zwischen 30 und 50°, liegt.The angle α is understood to mean the angle between the lateral surface and the base surface of the conical or frustoconical part, which is between 1 and 89 °, preferably between 20 and 70 °, particularly preferably between 30 and 50 °.
Die Grundfläche des kegel- oder kegelstumpfförmigen Teils kann hierbei kreisförmig, el- liptisch, dreieckig, quadratisch, sechseckig, vieleckig oder sternförmig sein.The base of the conical or frustoconical part can be circular, elliptical, triangular, square, hexagonal, polygonal or star-shaped.
Eine Weiterbildung der Erfindung sieht vor, dass der kegel- oder kegelstumpfförmige Teil gerade oder schief ist.A further development of the invention provides that the conical or frustoconical part is straight or crooked.
Vorzugsweise bildet der kegel- oder kegelstumpfförmige Teil den Hauptteil, also den größten Teil des in die Lauffläche eingebrachten Körpers. Durch die große Oberfläche des kegel- oder kegelstumpfföπnigen Teils wird eine große vertikale Kraft und damit eine entsprechend große Haftung des Spikes in der Lauffläche des Fahrzeugreifens sichergestellt.The conical or frustoconical part preferably forms the main part, that is to say the largest part of the body introduced into the tread. The large surface of the conical or frustoconical part ensures a large vertical force and thus a correspondingly high adhesion of the spike in the tread of the vehicle tire.
Der in die Lauffläche des Fahrzeugreifens eingebrachte Körper umfasst vorzugsweise einen Stift, der form- und/oder kraftschlüssig im Körper eingebettet ist und mit einem Ende aus der Lauffläche des Fahrzeugreifens herausragt, wobei der Stift vorzugsweise aus Hartmetall, Sintermetall oder dergleichen besteht. Der Körper des Spikes besteht vorzugsweise aus Metall, Kunststoff oder anderen verschleißfesten Werkstoffen besteht.The body introduced into the tread of the vehicle tire preferably comprises a pin which is embedded in the body in a positive and / or non-positive manner and with one end protruding from the tread of the vehicle tire, the pin preferably protruding Hard metal, sintered metal or the like is made. The body of the spike is preferably made of metal, plastic or other wear-resistant materials.

In den Fig. 1 bis 3 ist jeweils ein Spüce nach dem Stand der Technik in a) Seitenansicht und in b) Stirnansicht dargestellt, wobei gleiche Bezugsziffern jeweils gleiche Teile bezeichnen.1 to 3 each show a sink according to the prior art in a) side view and in b) end view, the same reference numerals designating the same parts.
Die in den Fig. 1 bis 3 dargestellten Spikes für die Lauffläche 1 eines hier nicht dargestellten Fahrzeugreifens bestehen aus einem Körper 2, der wenigstens teilweise in die Lauffläche 1 des Fahrzeugreifens eingefügt ist. Der Körper 2 umfasst eine plattenförmige Wurzel 7, mit welcher der Spike in der Nähe der hier nicht dargestellten oberen Gürtellage im Fahrzeugreifen verankert ist und die den größten Durchmesser der Spiketeile 6, 7, 8 oder 9 aufweist. Die Wurzel 7 ist in Fig. 1 über einen Halsteil 8 und in den Fig. 2 und 3 direkt mit einem Spikeoberteil verbunden, wobei der Spikeoberteil aus einem dickeren Spiketeil 9 und einem demgegenüber verjüngten Stift 6 besteht, der im Spiketeil 9 eingebettet ist und aus der Lauffläche 1 herausragt.The spikes shown in FIGS. 1 to 3 for the tread 1 of a vehicle tire, not shown here, consist of a body 2 which is at least partially inserted into the tread 1 of the vehicle tire. The body 2 comprises a plate-shaped root 7 with which the spike is anchored in the vehicle tire in the vicinity of the upper belt layer (not shown here) and which has the largest diameter of the spike parts 6, 7, 8 or 9. The root 7 is connected in Fig. 1 via a neck part 8 and in Figs. 2 and 3 directly to an upper spike part, the upper part of the spike consisting of a thicker spike part 9 and a tapered pin 6 which is embedded in the spike part 9 and from the tread 1 protrudes.
Alle Teile 6, 7, 8 oder 9 des in die Lauffläche 1 eingebrachten Körpers 2 sind zylinderfor- mig, besitzen also zwei Grundflächen, die parallel, eben, kongruent und durch eine Mantelfläche miteinander verbunden sind. Die Grundflächen können hierbei unterschiedliche Formen aufweisen. In Fig. 1 sind alle Teile 6, 7, 8 und 9 im Querschnitt kreisförmig. In Fig. 2 sind die Wurzel 7 und der Spiketeil 9 im Querschnitt kreisförmig, der Stift 6 dagegen im Querschnitt quadratisch. Schließlich sind in Fig. 3 die Wurzel 7 und der Spiketeil 9 im Querschnitt ovalförmig und der Stift 6 im Querschnitt sechseckig.All parts 6, 7, 8 or 9 of the body 2 introduced into the running surface 1 are cylindrical, that is to say they have two base surfaces which are parallel, flat, congruent and connected to one another by a lateral surface. The base areas can have different shapes. In Fig. 1, all parts 6, 7, 8 and 9 are circular in cross section. In Fig. 2, the root 7 and the spike part 9 are circular in cross section, the pin 6, however, is square in cross section. Finally, in FIG. 3 the root 7 and the spike part 9 are oval in cross section and the pin 6 is hexagonal in cross section.
Aus den Fig. 1 bis 3 wird deutlich, warum herkömmliche Spikes nach dem Stand der Technüc nur eine geringe Haftung in der Lauffläche 1 aufweisen, wenn Schnee-, Eis- und/oder Schmutzpartikel in den Raum zwischen Spike und elastischem Material der Lauf- fläche 1 eindringen. Die eindringenden Partikel drängen nämlich das elastische Material der Lauffläche 1 vom Körper 2 des Spikes derart weg, dass der Spüce aus der Lauffläche fallt, sobald der Form- und/oder Kraftschluss zwischen Spike und elastischem Material nicht mehr gegeben ist. Hierbei erniedrigen die Partikel insbesondere die Reiblcraft zwischen Spike und elastischem Material und wirken selbst quasi als Gleitmittel.From FIGS. 1 to 3 it is clear why conventional spikes according to the state of the art have only a slight adhesion in the tread 1 when snow, ice and / or dirt particles enter the space between the spike and the elastic material of the tread 1 penetrate. The penetrating particles namely push the elastic material of the tread 1 away from the body 2 of the spike in such a way that the sponge falls out of the tread as soon as the positive and / or non-positive connection between the spike and the elastic material is no longer present. The particles in particular lower the friction between the spike and the elastic material and act as a kind of lubricant.
In den Fig. 4 bis 6 ist jeweils ein erfindungsgemäßer Spike in a) Seitenansicht und in b) Stirnansicht dargestellt, wobei gleiche Bezugsziffern jeweils gleiche Teile bezeichnen. Die in den Fig. 4 bis 6 dargestellten Spikes für die Lauffläche 1 eines hier nicht dargestellten Fahrzeugreifens bestehen aus einem Körper 2, der wenigstens teilweise in die Lauffläche 1 des Fahrzeugreifens eingefügt ist. Der in Fig. 4 abgebildete Körper 1 umfasst eine plattenförmige Wurzel 7, die über einen Halsteil 8 mit einem Spüceoberteil verbunden ist, wobei der Spikeoberteil aus einem ringförmigen Vorsprung 10, einem erfindungsgemäßen kegelstumpfförmigen Teil 4und einem Stift 6 besteht, der im kegelstumpfförmigen Teil 4 eingebettet ist und aus der Lauffläche 1 herausragt. Während die Wurzel 7 und der Stift 6 im Quersclmitt oval ausgebildet sind, weisen der ringförmige Vorsprung 10 und der kegelstumpfförmige Teil 4 einen kreisförmigen Querschnitt auf.4 to 6 each show a spike according to the invention in a) side view and in b) end view, the same reference numerals designating the same parts. The spikes shown in FIGS. 4 to 6 for the tread 1 of a vehicle tire, not shown here, consist of a body 2 which is at least partially inserted into the tread 1 of the vehicle tire. The body 1 shown in Fig. 4 comprises a plate-shaped root 7, which is connected via a neck part 8 to an upper part of the sink, the upper part of the spike consisting of an annular projection 10, a frustoconical part 4 according to the invention and a pin 6 which is embedded in the frustoconical part 4 and protrudes from the tread 1. While the root 7 and the pin 6 are oval in cross-section, the annular projection 10 and the frustoconical part 4 have a circular cross section.
Der in Fig. 5 abgebildete Körper 2 umfasst ebenfalls eine plattenförmige Wurzel 7, die direkt mit einem Spikeoberteil verbunden ist, wobei der Spüceoberteil aus einem erfindungsgemäßen kegelstumpfförmigen Teil 4, der einen ringförmigen Vorsprung 10 aufweist, und einem Stift 6 besteht, der im kegelstumpfförmigen Teil 4 eingebettet ist und aus der Lauffläche 1 herausragt. Während die Wurzel 1, der kegelstumpfförmige Teil 4 und der ringförmige Vorsprung 10 im Querschnitt kreisförmig ausgebildet sind, weist der Stift 6 einen dreieckigen Querschnitt auf.The body 2 shown in FIG. 5 also comprises a plate-shaped root 7, which is connected directly to a spike upper part, the upper part of the purge consisting of a frustoconical part 4 according to the invention, which has an annular projection 10, and a pin 6, which is in the frustoconical part 4 is embedded and protrudes from the tread 1. While the root 1, the frustoconical part 4 and the annular projection 10 are circular in cross section, the pin 6 has a triangular cross section.
Der in Fig. 6 abgebildete Körper 2 ist sehr einfach aufgebaut und besteht lediglich aus einem kegelstumpfförmigen Teil 4 mit quadratischem Querschnitt und einem Stift 6 mit kreisförmigem Querschnitt, wobei der Stift 6 im kegelstumpfföimigen Teil 4 eingebettet ist und aus der Lauffläche 1 herausragt.The body 2 shown in FIG. 6 has a very simple structure and consists only of a frustoconical part 4 with a square cross section and a pin 6 with a circular cross section, the pin 6 being embedded in the frustoconical part 4 and protruding from the tread 1.
In Fig. 7 ist ein erfindungsgemäßer Spüce in Seitenansicht dargestellt. Vom prinzipiellen Aufbau entspricht dieser dem in Fig. 1 in a) Seitenansicht dargestellten Spüce, wobei gleiche Bezugsziffern gleiche Teile benennen. Der Spike in 7 unterscheidet sich von dem Spi- ke in Fig. 1 erfindungsgemäß dadurch, dass anstelle des zylindrischen dickeren Spiketeils 9 ein kegelstumpfförmiges Teil 4 vorgesehen ist.7 shows a spice according to the invention in a side view. In principle, this corresponds to the spüce shown in FIG. 1 in a) side view, the same reference numerals designating the same parts. The spike in FIG. 7 differs from the spike in FIG. 1 according to the invention in that a truncated cone-shaped part 4 is provided instead of the cylindrical, thicker spike part 9.
Durch den in den Fig. 4 bis 7 dargestellte kegelstumpfförmige Teil 4 des Körpers 2 wird eine bessere Haftung der Spüces in der Lauffläche 1 erreicht. Dies ist auf die geänderte Kraftverteilung des auf den kegelstumpfförmigen Teil 4 des Spücekörpers 2 wirkenden elastischen Materials der Lauffläche 1 zurüclczuführen. Hierbei wirken zwei in Fig. 8 dargestellte Kraftkomponenten, nämlich einerseits eine vertikale Kraft F(s) x cos α und andererseits eine radiale Kraft F(s) x sin α, wobei eine resultierende vertikale Kraft F(STOTA ) X cos α den Spike ins Innere des Fahrzeugreifens drückt. Der in Fig. 8 in Seitenansicht dargestellte Spüce entspricht im Aufbau dem Spüce aus Fig. 7, wobei gleiche Bezugsziffern gleiche Teile bezeichnen. The frustoconical part 4 of the body 2 shown in FIGS. 4 to 7 improves the adhesion of the spices in the tread 1. This is due to the changed force distribution of the elastic material of the tread 1 acting on the frustoconical part 4 of the washing body 2. 8, namely a vertical force F (s) x cos α and a radial force F (s) x sin α, with a resulting vertical force F (S TOT A) X cos α Spike presses inside the vehicle tire. The spüce shown in side view in FIG. 8 corresponds in structure to the spüce from FIG. 7, with the same reference numerals designating the same parts.
