Abstract

The tire(1) is for mounting on a supporting tube and has rolling section comprising a blunt wedge-shape or a dome-shape. A ring shaped chamber(4) in the rolling section is filled with a non-gaseous material(5) different to that from which the tire is manufactured. Material in the hollow chamber(4) is an economic filler(5) such as an expanded foam or polystyrene foam. INORGANIC CHEMISTRY - An alternative filling is a fiberous material, e.g. hemp. An independent claim is included for a manufacturing process for the semi-hollow tire in which a ring-shaped core of filler material(5) is positioned in a molding tool and polyurethane is cast around the core to mold the tire structure.

Description

Die Erfindung betrifft einen Halbhohlreifen gemäß des Oberbegriffes des Patentanspruches 1.The The invention relates to a half-hollow tire according to the preamble of the claim 1.

Ein derartiger Halbhohlreifen ist beispielsweise in der EP 0 878 328 B1 beschrieben. Dieser Halbhohlreifen besteht aus einem Gummimaterial und ist aus Strangprofil hergestellt. Der Hohlraum in den keilringförmig ausgebildeten Halbhohlreifen macht den Hohlreifen erst preiswert, weil viel Material eingespart werden kann, im Gegensatz zu einem Vollgummiprofil. Darüber hinaus hat der Hohlraum in dem Halbhohlraumreifen den Vorteil, dass er ein vorteilhaftes Walken zwecks Selbstreinigung des Reifens ermöglicht.Such a half-hollow tire is for example in the EP 0 878 328 B1 described. This semi-hollow tire consists of a rubber material and is made of extruded profile. The cavity in the wedge-shaped semi-hollow tires makes the hollow tires only inexpensive, because much material can be saved, in contrast to a solid rubber profile. Moreover, the cavity in the half-cavity tire has the advantage of enabling advantageous walking for self-cleaning of the tire.

Die Herstellung des Halbhohlreifens aus Gummi ist jedoch aufgrund des relativ langen Ausvulkanisierungsprozesses recht teuer.The However, production of the half-hollow rubber tire is due to the relatively long Ausvulkanisierungsprozesses quite expensive.

Der Erfindung liegt die Aufgabe zugrunde, einen preiswerten und leicht verformbaren Halbhohlreifen mit umlaufendem Innenraum zu schaffen.Of the Invention is based on the object, a cheap and easy to create deformable half-hollow tires with circumferential interior.

Diese Aufgabe wird erfindungsgemäß durch das kennzeichnende Merkmal des Patentanspruches 1 gelöst. Infolge dieser Maßnahme kann ein einfaches Herstellverfahren verwendet werden, weil ein leicht verformbares bzw. ein den Reifen leicht das Walken ermöglichendes Füllmaterial in das die Reifenhaut bildende Material eingelegt werden kann.These The object is achieved by the Characteristic feature of claim 1 solved. As a result this measure A simple manufacturing process can be used because an easy one deformable or easily permitting the tire to be walked on filling material in which the tire skin forming material can be inserted.

Hierbei ist vorgesehen, dass das Material, aus dem der Reifen hergestellt ist, Polyuhrethan (PUR) ist. Dieses Material ist zwar teurer als Gummi, jedoch auch aufgrund des preiswerteren Herstellverfahrens, in dem Polyuhrethan in eine einfache Gießform gegossen wird, ist der Reifen preiswert herstellbar.in this connection It is provided that the material from which the tire is made is, Polyurethane (PUR) is. This material is more expensive than Rubber, but also due to the cheaper manufacturing process, in which Polyuhrethan is poured into a simple mold, is the Tires reasonably priced.

Hierbei kann das Material in dem Hohlraum ein preiswertes Füllstoffmaterial wie beispielsweise Schaumstoff, Styropor, Fasermaterial, wie Hanf etc. sein. Dieses preiswerte Material wird dann mit einer Haut aus PUR, sozusagen als Überzug, überzogen.in this connection For example, the material in the cavity may be an inexpensive filler material such as foam, polystyrene, fiber material, such as hemp etc. be. This inexpensive material is then made with a skin PUR, coated as it were.

Hierbei lässt sich mittels eines Herstellverfahrens, der Halbhohlreifen einfach dadurch herstellen, dass in einer Gießform der Füllring eingelegt und im Gießverfahren mit Polyuhrethan (PUR) umgossen wird.in this connection let yourself by means of a manufacturing process, the half-hollow tires simply by make that in a mold the filler ring inserted and in the casting process with polyurethane (PUR) is poured.

1 den Halbhohlrahmen in Seitenansicht, 1 the half-hollow frame in side view,

2 den Halbhohlreifen im Schnitt II-II und 2 the half-hollow tires in section II-II and

3 den Querschnitt im vergrößerten Maßstab. 3 the cross-section on an enlarged scale.

Der Halbhohlreifen 1 wird auf ein nicht dargestelltes Tragrohr aufgezogen. Hierbei werden mehrere Halbhohlreifen 1 mittels nicht dargestellter Abstandsringen zueinander auf Abstand gehalten und beabstandet auf dem Tragrohr aufgefädelt und bilden dann zusammen eine sogenannte Keilringwalze, wobei die Halbhohlreifen 1 keilringförmige Furchen in den Boden drücken und hierbei den Boden verdichten.The half-hollow tire 1 is mounted on an unillustrated support tube. Here are several semi-hollow tires 1 held spaced apart by means not shown spacer rings spaced and threaded on the support tube and then together form a so-called wedge ring roller, wherein the half-hollow tires 1 Keilring-shaped furrows press into the ground and thereby compact the soil.

Jeder Halbhohlreifen 1 weist einen Rollabschnitt 2 mit einem abgestumpften keilförmigen oder domförmigen Profil 3 auf. Innerhalb des Rollabschnittes 2 ist ein umlaufender ringförmiger Raum 4 angeordnet. Dieser ringförmige Raum 4 ist mit einem anderen, nicht gasförmige Material 5 aus dem der Hohlreifen 1 gefertigt ist, gefüllt. Der Reifen 1 ist aus Polyuhrethan (PUR) hergestellt. In dem Hohlraum 4 befindet sich ein preiswertes Füllstoffmaterial 5, wie beispielsweise Schaumstoff, Styropor oder Fasermaterial wie Hanf. Der Halbhohlreifen 1 wird in einer nicht dargestellten Gießform hergestellt. Hierzu wird zunächst der Füllring 6 in die Gießform eingelegt. Anschließend wird im Gießverfahren mit Polyuhrethan der Füllring 6 umgossen, so dass das Polyuhrethan eine Haut 7 um das Einlegeformteil 6 bildet. Das Füllstoffmaterial 5 ist so gewählt, dass es, trotz dass es sich in dem Hohlraum befindet, die Walkfähigkeit des Polyuhrethanshohlreifens 1 nicht wesentlich behindert.Each semi-hollow tire 1 has a rolling section 2 with a truncated wedge-shaped or domed profile 3 on. Within the rolling section 2 is a circumferential annular space 4 arranged. This annular space 4 is with another, non-gaseous material 5 from the hollow tire 1 is made, filled. The mature 1 is made of Polyurethane (PUR). In the cavity 4 is an inexpensive filler material 5 , such as foam, polystyrene or fiber material such as hemp. The half-hollow tire 1 is produced in a mold, not shown. For this purpose, first the filler ring 6 inserted in the mold. Subsequently, in the casting process with Polyuhrethan the filler ring 6 poured over, so that the Polyuhrethan a skin 7 around the insert molding 6 forms. The filler material 5 is chosen so that, despite being in the cavity, the flexing ability of the polyhedron rubber tire 1 not significantly impeded.
