Abstract

Eine Hydraulikleitung für Kraftfahrzeuge besitzt eine Außenschicht aus Kunststoff, eine Innenschicht aus Polyamid und eine Zwischenschicht aus armierenden Fäden. Die Fäden sind schraubenlinienförmig gewickelt.A hydraulic line for motor vehicles has an outer layer made of plastic, an inner layer made of polyamide and an intermediate layer made of reinforcing threads. The threads are wound helically.

Description

Die Erfindung betrifft eine Hydraulikleitung für Kraftfahr­ zeuge mit einer Kunststoffaußenschicht, einer Innenschicht aus Polyamid und einer Zwischenschicht aus armierenden Fä­ den.The invention relates to a hydraulic line for motor vehicles witness with a plastic outer layer, an inner layer made of polyamide and an intermediate layer of reinforcing thread the.

Bei bekannten Hydraulikleitungen dieser Art besteht die ar­ mierende Zwischenschicht aus geflochtenen Fäden. Die Her­ stellung derartiger Hydraulikleitungen erfolgt in der Wei­ se, daß zunächst die Innenschicht extrudiert werden muß. Anschließend wird das die Innenschicht bildende extrudierte und abgekühlte Rohr in eine Flechtmaschine eingesetzt und dient dort als Träger für die geflochtene, armierende Zwi­ schenschicht. Anschließend wird in einem weiteren Extruder die Außenschicht auf die geflochtene Zwischenschicht aufex­ trudiert.In known hydraulic lines of this type, the ar lubricating intermediate layer made of braided threads. The Her Position of such hydraulic lines takes place in Wei se that the inner layer must first be extruded. Subsequently, the one that forms the inner layer is extruded and cooled tube inserted in a braiding machine and serves as a carrier for the braided, reinforcing intermediate layer. Then in another extruder the outer layer onto the braided intermediate layer trudged.

Die Herstellung derartiger Hydraulikleitungen ist aufwen­ dig, da sie in drei vollständig voneinander getrennten Schritten und auf drei unterschiedlichen Maschinen erfolgen muß. Die Trennung der einzelnen Verfahrensschritte ist des­ halb erforderlich, weil für das gesamte Fertigungsverfahren die Flechtgeschwindigkeit limitierend ist. Diese ist soviel geringer als die Extrusionsgeschwindigkeit der einzelnen Schichten, daß eine Fertigung in einem Arbeitsgang noch un­ rentabler ist als die bisher übliche Fertigung auf drei un­ terschiedlichen Maschinen.The production of such hydraulic lines is expensive dig since they are in three completely separate from each other  Steps and on three different machines got to. The separation of the individual process steps is the half required because of the entire manufacturing process the braiding speed is limiting. This is so much less than the extrusion speed of the individual Layers that a production in one operation is still un is more profitable than the usual production on three un different machines.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Hydraulikleitung der als bekannt vorausgesetzten Art so auszubilden, daß sie besonders ein­ fach und schnell auf möglichst wenigen unterschiedlichen Maschinen gefertigt werden kann.The invention is based on this prior art based on the task of a hydraulic line known as assumed type so that it is particularly a quickly and easily on as few different as possible Machines can be manufactured.

Die Lösung dieser Aufgabe erfolgt dadurch, daß die Fäden schraubenlinienförmig gewickelt sind.This problem is solved in that the threads are wound helically.

Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Preferred embodiments of the invention result from the subclaims.

Die Ausbildung der armierenden Zwischenschicht als Schicht aus schraubenlinienförmig gewickelten Fäden ermöglicht eine drastische Steigerung der Fertigungsgeschwindigkeit. Der Wickelvorgang läßt sich erheblich schneller durchführen als ein Flechtvorgang. Darüber hinaus kann die Fertigung bei der neuen Ausbildung der Hydraulikschläuche kontinuierlich erfolgen.The formation of the reinforcing intermediate layer as a layer made of helically wound threads enables one drastic increase in production speed. The Winding process can be carried out much faster than a braiding process. In addition, the manufacturing at the new training of hydraulic hoses continuously respectively.

Die Erfindung wird anhand der Zeichnung nachstehend im ein­ zelnen erläutert. The invention is based on the drawing below in a individual explained.  

Die Zeichnung zeigt einen schematischen Längsschnitt durch eine Hälfte der Hydraulikleitung.The drawing shows a schematic longitudinal section through half of the hydraulic line.

Die Hydraulikleitung besitzt eine Mittelachse 4. Eine In­ nenschicht ist mit 2 bezeichnet. Auf die Innenschicht 2 ist eine Wickelschicht 3 aufgewickelt, die aus Fäden 3a be­ steht. Die Fäden 3a sind aneinanderliegend einlagig gewic­ kelt. Die Fäden bestehen aus Einzelfäden, die miteinander verflochten oder verzwirnt sind. Auf die Zwischenschicht 3 ist die Außenschicht 1 aufextrudiert. Derartige Hydrau­ likleitungen weisen einen maximalen Innendurchmesser di von nur 3,0 mm auf. Es handelt sich also um vergleichsweise dünne und flexible Hydraulikleitungen, die sehr druckfest ausgebildet sein müssen.The hydraulic line has a central axis 4 . An inner layer is denoted by 2. On the inner layer 2 , a winding layer 3 is wound, which consists of threads 3 a be. The filaments 3a are adjacent to one another Celtic ply gewic. The threads consist of individual threads that are intertwined or twisted together. On the intermediate layer 3, the outer layer 1 is extruded. Such hydraulic lines have a maximum inside diameter d i of only 3.0 mm. It is therefore comparatively thin and flexible hydraulic lines, which must be designed to be very pressure-resistant.
