Description

Lauffläche für Luftreifen Die Erfindung bezieht sich auf :eine Lauffläche für Luftreifen, deren Bodengriffigkeit durch :eine bekannte Feinschnittausführuing erhöht ist, wobei die Feineinschnitte am Grunde eine Erweiterung erfahren, wodurch u. a. die Kerbwirkung nicht unwesentlich verringert wird.Tread for Pneumatic Tires The invention relates to: a tread for pneumatic tires whose grip on the ground is due to: a well-known fine-cut design is increased, with the fine incisions at the bottom experience an expansion, whereby i.a. the notch effect is not insignificantly reduced.

Die Erfindung beruht demgegenüber nun darauf, diese Auskehlungen gegen die Enden hin trichterförmig zu erweitern, wodurch die in die Feinschnitte eingedrungenen Fremdkörper, wie Sand, Sträßenkot u. dgl., durch die Walkbewegung des Mantels beim Fahren leichter herausgedrängt werden können.In contrast, the invention is now based on these grooves against to widen the ends in the shape of a funnel, whereby the penetrated into the fine cuts Foreign bodies such as sand, street excrement and the like, due to the flexing movement of the coat Driving can be pushed out more easily.

In der Zeichnung sind zwei Ausführungsbeispiele veranschaulicht. Abb. r und 3 stellen Querschnitte von erfindungsgemäß ausgebildeten Laufflächen für Luftbereifungen dar. Abb.2 und 4 sind Ansichten senkrecht dazu.Two exemplary embodiments are illustrated in the drawing. Fig. r and 3 represent cross sections of treads designed according to the invention for pneumatic tires Fig. 2 and 4 are views perpendicular thereto.

Den. Ausführungsbeispielen nach Abb. r und 2 bzw. Abb.3 und 4 liegt eine: Lauffläche r mit einem aus Klötzen 2, Längsrippen o. dgl. bestehenden Laufflächenmuster zugrunde. Diese: Klötze bzw. Längsrippen sind in bekannter Weise zur Erhöhung der Bodengriffigkeit mit im wesentlichen quer zur Laufrichtung verlaufenden Feinschiiitten 3 versehen. Am Grunde weisen diese Feinschnitte ,; bekannte Auskehlungen 4 .auf.The. Embodiments according to Fig. R and 2 or Fig.3 and 4 is located a: tread r with a tread pattern consisting of blocks 2, longitudinal ribs or the like underlying. These: blocks or longitudinal ribs are known to increase the Ground grip with fine cuts running essentially transversely to the direction of travel 3 provided. At the bottom, these fine cuts show,; known grooves 4.

Erfindungsgemäß erweitern sich diese Auskehlungen gegen ihre Enden 5 hin trichterförmig, wodurch der bereits erwähnte Vorteil des Auss@to:ßens von Sand, Stra13enk#-,t o. dgl. erreicht wird.According to the invention, these grooves widen towards their ends 5 funnel-shaped, whereby the already mentioned advantage of the out @ to: ßens of Sand, Stra13enk # -, t or the like is reached.
