Abstract

The vehicle pneumatic tire has a tread (2) of a synthetic rubber vulcanized to the tire carcass (1), with a profile of raised blocks (4-10) with channels (14,15) and water inflow/outflow openings (17,18). The channels, in parallel, both extend across the whole profile and are also separated at the center.

Description

Die Erfindung bezieht sich auf einen pneumatischen Fahrzeugreifen, der als Unterbau eine Karkasse aufweist, auf welcher eine aus z.B. synthetischem Kunststoff bestehende Laufsohle aufvulkanisiert ist, wobei letztere eine Profilierung erhält.The The invention relates to a pneumatic vehicle tire which as a substructure has a carcass on which one of e.g. synthetic Plastic existing outsole is vulcanized, the latter receives a profiling.

Diese in vielfacher Formgebung bekannten und der besseren Bodenhaftung wegen mit erhabenen und aus möglichst abriebfesten Materialmischungen bestehenden Wülsten gefertigten Profile zeitigen zwar zumeist eine gute Bodenhaftung, sind indessen bei mit Wasser überzogenen Fahrbahnen oftmals mangelhaft und vermögen nur selten in extremen Fällen dem "Aufschwimmen" des Fahrzeuges (Aquaplaning) entgegen zu wirken.These known in many forms and better grip because of with sublime and as possible abrasion-resistant material mixtures existing profiles produced beads Although mostly a good grip, but are covered with water Lanes are often deficient and rarely able in extreme make the "floating" of the vehicle (aquaplaning) counteract.

Hier setzt nun die Erfindung ein, deren Aufgabe darin zu sehen ist, die Laufsohle bzw. deren Profilierung so zu gestalten, dass der Effekt des gefürchteten "Aquaplanings" nahezu völlig eliminiert wird.Here now uses the invention, the task of which is to see the Outsole or its profiling to be shaped so that the effect of the dreaded "aquaplaning" almost completely eliminated becomes.

Die Lösung dieser Aufgabe besteht darin, dass die erhabenen Wülste mit Kanäle versehen sind, denen Zu- und Ablauföffnungen zugeordnet sind.The solution this task is that the raised beads with channels are provided, which are associated with inlet and outlet openings.

Aus dem Vorstehenden und später noch zu beschreibenden Zeichnung wird verständlich, dass auf diese erfinderische Weise eine wesentliche verbesserte Verdrängung des Wassers von der Fahrbahn erzielt wird und somit die angestrebte Bodenhaftung erhalten bleibt.Out the above and later Still to be described drawing will understand that on this inventive Way a substantial improved displacement of the water from the roadway achieved and thus the desired traction is maintained.

Als besonders vorteilhaft sich ergeben, dass nach einem weiteren Merkmal der Erfindung vorgesehen ist, dass sich die Kanäle sowohl durchgehend als auch etwa mittig getrennt über die gesamte Profilbreite erstrecken.When particularly advantageous result that for a further feature the invention is provided that the channels both continuously and also about center separated over extend the entire profile width.

Desweiteren ist es für den Ablauf bzw. Abweisung des Wassers in weiterer Ausgestaltung der Erfindung von Vorteil, dass die Kanäle parallel zueinander verlaufen.Furthermore is it for the course or rejection of the water in a further embodiment The invention of advantage that the channels are parallel to each other.

Schließlich ist es von weiterem Vorteil, dass sich die Kanäle zu ihren Auslaufenden erweitern.Finally is It further has the advantage that the channels expand to their outlet ends.

Die Erfindung ist in einem Ausführungsbeispiel auf der Zeichnung dargestellt, wobei es sich um einen Reifen handelt, der mittig auf seinem Umfang einen durchlaufenden Wulst aufweist, der in diesem Fall nicht mit einem Kanal versehen ist, sondern den Reifen in zwei kongruente Hälften abgrenzt.The Invention is in one embodiment on the drawing, which is a tire, which has a continuous bead in the middle of its circumference, which is not provided in this case with a channel, but the Tires in two congruent halves demarcates.

Es zeigen:It demonstrate:

1 einen Querschnitt und 1 a cross section and

2 eine Draufsicht auf einen Teil des Reifens 2 a plan view of a part of the tire

Auf einer Karkasse 1, deren Seitenwände 3 nur teilweise und die üblichen Reifenwülste nicht mitgezeichnet wurden, ist in bekannterweise eine nicht bezifferte Profilierung mit erhabenen Wülsten 4 bis 10 aufvulkanisiert.On a carcass 1 whose side walls 3 only partially and the usual tire beads were not drawn, is in a known way an unnumbered profiling with raised beads 4 to 10 vulcanized.

Der mittig verlaufende kanallose Wulst 7 der Profilierung teilt die Laufsohle 2 des Reifens in zwei Kongruente Teile 12 und 13 (s. 1), wobei die Wülste 4 bis 6 mit den Kanälen 14, die Wülste 8 bis 10 dagegen mit den Kanälen 15 in Verbindung stehen. Allen Kanälen sind jedoch die Zu- und Ablauföffnungen 17 und 18 zugeordnet.The central channelless bulge 7 the profiling shares the outsole 2 of the tire in two congruent parts 12 and 13 (S. 1 ), with the beads 4 to 6 with the channels 14 , the beads 8th to 10 against it with the channels 15 keep in touch. All channels, however, are the inlet and outlet openings 17 and 18 assigned.

Die Wirkungsweise der Anordnung ist etwa folgende:
Nah der erfinderisch gestalteten Profilierung bzw. Laufsole 2 kann sich ansammelndes Wassers nicht unter dem Reifen aufbauen, da es durch die Vielzahl der in den Wülsten der befindlichen Kanäle und der Zu- und Ablauföffnungen weitgehende seitlich verdrängt wird. Es kann sich also ein "Aufschwimmen" des Reifens nicht einstellen.
The operation of the arrangement is approximately the following:
Close to the inventive designed profiling or running brine 2 can not build up accumulating water under the tire, as it is displaced by the large number of located in the beads of the existing channels and the inlet and outlet openings laterally. So it can not be a "floating" of the tire to adjust.

Durch den Anpressdruck der Laufsohle auf die Fahrbahn wird das Wasser durch die Zu- und Ablauföffnungen also seitlich des Reifens abgestoßen.By the pressure of the outsole on the road becomes the water through the inlet and outlet openings So repelled the side of the tire.

Fernerhin wird durch die Turbulenz der Reifen zusätzlich das Wasser von der Fahrbahn durch die Kanäle und den Zu- und Ablauföffnungen nach oben, um die Reifen herum geleitet und auch dort letztlich abgeleitet.henceforth In addition, due to the turbulence of the tires, the water from the road surface becomes through the channels and the inlet and outlet openings headed up to the tires around and there as well derived.

Dadurch, dass die seitwärts verlaufenden Kanäle in Fahrtrichtung nach hinten verlaufen, ergibt sich ein Unterdruck, so dass schon durch die Fliehkraft des rollenden Reifens das eingetretene Wasser nach außen weg geleitet wird. Deshalb müssen allerdings die Reifen in Fahrtrichtung richtig montiert werden.Thereby, that the sideways running channels run in the direction of travel to the rear, there is a negative pressure, so that already occurred by the centrifugal force of the rolling tire Water to the outside is directed. That's why However, the tires are mounted correctly in the direction of travel.

Schließlich ist weiterer Vorteil der Erfindung darin zu sehen, dass nach Materialabrieb der Profilierung die Kanäle dies sichtbar anzeigen und kenntlich machen, dass eine baldige Reifenerneuerung notwendig ist.Finally is Another advantage of the invention is the fact that after material abrasion profiling the channels visibly indicate this and indicate that an early tire renewal necessary is.

Je nach Reifenart und deren Größe können eine entsprechende Anzahl von Kanälen – die übrigens mit Rücksicht auf die Art der Profilgebung nicht grundsätzlich parallel zueinander verlaufen – mit Zu- und Ablauföffnungen angeordnet werden.ever according to the type of tire and its size can corresponding number of channels - the way with consideration on the type of profiling is not basically parallel to each other run - with Inlet and outlet openings to be ordered.
