Abstract

Cooling water for motor vehicles passes through a flexible hose consisting of several plastic layers (1,2,3), of which the inner layer is of polyvinylidene fluoride. The inner layer is pref. surrounded by an adhesion promoting layer of the same material, which is in turn surrounded by an outer layer of polyamide. Pref. polyamides are PA 11 and PA 12.

Description

Die Erfindung betrifft eine flexible Kühlwasserleitung für Kraftfahrzeuge.The invention relates to a flexible cooling water pipe for Motor vehicles.

Bisher sind als flexible Kühlwasserleitungen für Kraftfahr­ zeuge ausschließlich armierte Gummischläuche bekannt. Von derartigen Kühlwasserleitungen wird neben einer hohen Fle­ xibilität eine Beständigkeit insbesondere auch gegenüber Glykol und anderen Kühlwasserzusätzen verlangt. Darüber hinaus müssen die Kühlwasserleitungen eine gute Beständig­ keit bis in niedere Temperaturbereiche von -40°C und in hohe Temperaturbereiche bis +120°C aufweisen.So far as flexible cooling water pipes for motor vehicles witness only known reinforced rubber hoses. From Such cooling water pipes is in addition to a high Fle xibility a resistance especially to Glycol and other cooling water additives are required. About that In addition, the cooling water pipes must have a good resistance in low temperature ranges of -40 ° C and in have high temperature ranges up to + 120 ° C.

Diese Vorgaben haben dazu geführt, daß bisher ausschließ­ lich armierte Gummischläuche als flexible Kühlwasserlei­ tungen eingesetzt worden sind.These requirements have led to the fact that so far Reinforced rubber hoses as flexible cooling water pipes have been used.

Die Herstellung von armierten Gummischläuchen zur Verwen­ dung als Kühlwasserleitungen ist aufwendig und teuer.The production of reinforced rubber hoses for use dung as cooling water pipes is complex and expensive.

Der Erfindung liegt die Aufgabe zugrunde, flexible Kühlwas­ serleitungen für Kraftfahrzeuge zu schaffen, die aus Kunst­ stoff extrudierbar sind.The invention has for its object flexible cooling water To create wiring for motor vehicles made of art are extrudable.

Die Lösung dieser Aufgabe erfolgt mit den Merkmalen des Kennzeichnungsteils von Anspruch 1. Bevorzugte Ausführungs­ formen sind in den Unteransprüchen beschrieben.This problem is solved with the features of Labeling part of claim 1. Preferred embodiment shapes are described in the subclaims.

Das Vorsehen einer Innenschicht aus PVDF bei gleichzeitigem Aufbau der Kühlwasserleitung aus mehreren Kunststoffschich­ ten führt zu einer Kühlwasserleitung, die den hohen ge­ stellten Anforderungen entspricht. Dabei erweist es sich als besonders vorteilhaft, daß die innere Kunststoffschicht aus PVDF von einer Haftvermittlerschicht umschlossen ist, die im wesentlichen ebenfalls aus PVDF besteht. Für die weitere Außenschicht erweist sich die Verwendung von Poly­ amid als sehr hilfreich.The provision of an inner layer of PVDF at the same time Construction of the cooling water pipe from several plastic layers ten leads to a cooling water pipe, which the high ge meets the requirements. Here it turns out as particularly advantageous that the inner plastic layer made of PVDF is enclosed by an adhesive layer, which essentially also consists of PVDF. For the Another outer layer proves the use of poly amid as very helpful.

Die besonders bevorzugte Kühlwasserleitung weist eine In­ nenschicht aus PVDF auf und eine Außenschicht aus PA 11 oder PA 12. Zwischen Außenschicht und Innenschicht ist eine Haftvermittlerschicht vorgesehen, die zumindest im wesent­ lichen aus PVDF besteht. Eine solche flexible Kühlwasser­ leitung erweist sich bei Dauerversuchen als geeignet, alle hohen Ansprüche an flexible Kühlwasserleitungen für Kraft­ fahrzeuge zu erfüllen. So wird eine ausreichende Tempera­ turbeständigkeit gegen niedrige und hohe Temperaturen er­ zielt, außerdem ergibt sich eine ausreichende Beständigkeit gegen Glykol oder andere Gefrierschutzmittel bzw. übliche Kühlwasserzusätze.The particularly preferred cooling water line has an In layer made of PVDF and an outer layer made of PA 11 or PA 12. There is one between the outer layer and the inner layer Adhesion promoter layer provided, which at least essentially made of PVDF. Such flexible cooling water Cable proves to be suitable for endurance tests, all high demands on flexible cooling water pipes for power vehicles to meet. So a sufficient tempera Resistance to low and high temperatures aims, and there is also sufficient durability against glycol or other antifreeze or usual Cooling water additives.

Nachstehend wird eine bevorzugte Ausführungsform der Er­ findung anhand der Zeichnung im einzelnen erläutert. Es zeigen:A preferred embodiment of the Er invention explained in detail using the drawing. It demonstrate:

Fig. 1 einen Längsschnitt durch eine dreischichtige flexible Kühlwasserleitung, Fig. 1 shows a longitudinal section through a three-layered flexible cooling water line,

Fig. 2 einen Querschnitt entlang II-II in Fig. 1. FIG. 2 shows a cross section along II-II in FIG. 1.

Die zeichnerische Darstellung ist nicht maßstabsgerecht. Zur Verdeutlichung sind außerdem die drei Schichten im oberen Bereich der Fig. 1 unterschiedlich lang ausgebil­ det.The graphic representation is not to scale. For the sake of clarity, the three layers in the upper region of FIG. 1 are also of different lengths.

Eine Innenschicht 1 aus Polyvinylidenfluorid (PVDF) weist bevorzugt eine Schichtdicke in der Größenordnung von 0,1 bis 0,3 mm auf. Die Innenschicht 1 ist von einer Haftver­ mittlerschicht 2 umschlossen, die zumindest im wesentlichen ebenfalls aus PVDF besteht. Deren Dicke liegt in der Praxis in der Größenordnung von 0,05 bis 0,15 mm. Eine äußere Kunststoffschicht besteht bevorzugt aus Polyamid in einem Dickenbereich von 0,7 bis 1,5 mm. Als geeignet haben sich PA 11 und PA 12 erwiesen.An inner layer 1 made of polyvinylidene fluoride (PVDF) preferably has a layer thickness of the order of 0.1 to 0.3 mm. The inner layer 1 is surrounded by an adhesive layer 2 , which at least essentially also consists of PVDF. In practice, their thickness is on the order of 0.05 to 0.15 mm. An outer plastic layer is preferably made of polyamide in a thickness range of 0.7 to 1.5 mm. PA 11 and PA 12 have proven to be suitable.
