Abstract
Description
Die Erfindung betrifft einen Schlauchabschnitt nach dem Oberbegriff des Patentanspruches 1.The The invention relates to a hose section according to the preamble of claim 1.
Schläuche werden als Endlosschläuche (so genannte Meterware) durch Extrudieren oder Vulkanisieren hergestellt und weisen einen im Wesentlichen geradlinigen Verlauf auf. Aufgrund ihrer Flexibilität und Elastizität, bedingt durch elastomere Werkstoffe wie Gummi bzw. Kautschuk, können sie bis zu bestimmten Krümmungsradien gebogen werden, wobei sich aufgrund der elastischen Biegung Rückstellkräfte ergeben, welche den gekrümmten Schlauch in eine gerade Ausrichtung zurückzustellen versuchen. Bei bestimmten technischen Anwendungen, z. B. in Kältemittelkreisläufen für Klimaanlagen von Kraftfahrzeugen werden Schläuche mit Umlenkungen bzw. Krümmungen in verschiedenen Ebenen gefordert, welche mit Endlosschläuchen nicht darstellbar sind. Man hat daher für derartige Anwendungen so genannte Formschläuche oder geformte Schlauchabschnitte vorgesehen, wobei der Schlauch nicht als Endlosschlauch, sondern durch Spitzgießen in einer Form hergestellt wird. Dadurch kann ein Schlauchabschnitt mit beständigem gekrümmtem Verlauf hergestellt werden. Derartige Formschläuche werden als Verbindungsstücke zwischen festen Anschlussstellen eines Flüssigkeitskreislaufes verwendet. Nachteilig bei einem Formschlauch sind die Herstellkosten, bedingt durch die relativ hohen Werkzeugkosten.Hoses become as endless hoses (so-called yard goods) produced by extrusion or vulcanization and have a substantially rectilinear course. by virtue of their flexibility and elasticity, due to elastomeric materials such as rubber or rubber, they can up to certain radii of curvature be bent, resulting in due to the elastic bending restoring forces, which the curved one Try to reset the tube to a straight orientation. at certain technical applications, eg. B. in refrigerant circuits for air conditioning of motor vehicles become hoses with deflections or bends required in different levels, which with endless hoses not are representable. It has therefore for such applications so-called Molded hoses or formed hose sections, wherein the hose is not as an endless tube, but manufactured by injection molding in a mold becomes. This allows a hose section with a consistent curved course getting produced. Such molding tubes are used as connecting pieces between fixed connection points of a fluid circuit used. A disadvantage of a molded hose is the production costs, due to the relatively high tooling costs.
Es ist Aufgabe der vorliegenden Erfindung, einen Schlauchabschnitt der eingangs genanten Art, d. h. mit einem gekrümmten, vorzugsweise räumlich gekrümmten Verlauf zu niedrigen Herstellkosten zu schaffen.It Object of the present invention, a hose section of the type mentioned in the beginning, d. H. with a curved, preferably spatially curved course to create low production costs.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst.These The object is solved by the features of claim 1.
Erfindungsgemäß ist vorgesehen, dass ein Schlauchabschnitt von einem Endlosschlauch (Meterware) verwendet und in einen gekrümmten Schlauchhalter zur Erzielung einer definierten Krümmung eingelegt wird. Dabei stützt sich der Schlauchabschnitt mit seiner äußeren Biegezone gegen den Schlauchhalter ab, welcher im Querschnitt etwa halbschalenförmig ausgebildet ist und die Rückstellkräfte des gebogenen Schlauchabschnittes aufnimmt. Mit der erfindungsgemäßen Verbindung von Schlauch und Schlauchhalter wird der Vorteil erreicht, dass für einen beliebig gekrümmten Schlauchabschnitt ein preisgünstiger Endlosschlauch verwendet und auf einen kostenaufwändigen Formschlauch verzichtet werden kann. Der Schlauchhalter kann vorzugsweise als Kunststoffspritz- oder -blasteil hergestellt werden, so dass die Kombination aus Endlosschlauch und Schlauchhalter zu geringeren Kosten als ein Formschlauch herstellbar ist. Darüber hinaus ergibt sich der Vorteil, dass der gekrümmte Schlauchabschnitt durch den Schlauchhalter einen mechanischen Schutz im Bereich der äußeren Biegezonen erhält.According to the invention, it is provided that a hose section of an endless hose (sold by the meter) used and in a curved hose holder is inserted to achieve a defined curvature. there supports the hose section with its outer bending zone against the hose holder from, which is approximately half-shell-shaped in cross-section and the Restoring forces of the receives bent hose section. With the compound of the invention of hose and hose holder the advantage is achieved that for one arbitrarily curved hose section a cheaper Endless tube used and on a costly shaped tube can be waived. The hose holder may preferably as Plastic injection or blow molding are made, so that the combination Endless hose and hose holder at a lower cost than one Form hose can be produced. In addition, the results Advantage that the curved Hose section through the hose holder mechanical protection in the area of the outer bending zones receives.
Nach einer vorteilhaften Ausgestaltung der Erfindung sind an den Längsrändern des Schlauchalters Lappen vorgesehen, welche als Klammern oder Clipse wirken und den gekrümmten Schlauchabschnitt in seiner Position im Schlauchhalter fixieren. Der Schlauch kann somit weder im Schlauchhalter verrutschen noch aus dem Schlauchhalter austreten. Mit dem erfindungsgemäßen Schlauchhalter können Schlauchkrümmungen in unterschiedlichen, z. B. in um 90 Grad verschränkten Ebenen dargestellt werden. Damit kann der gekrümmte Schlauchabschnitt als Verbindungsstück zwischen Anschlussstutzen mit unterschiedlicher Lage und unterschiedlicher Achsausrichtung verwendet werden. Besonders vorteilhaft ist die Verwendung als Kältemittelschlauchabschnitt bzw. -verbindungsstück in einem Kältemittel kreislauf einer Klimaanlage für Kraftfahrzeuge. Hierzu werden die Schlauchenden mit entsprechenden Kältemittelanschlussrohren versehen.To an advantageous embodiment of the invention are at the longitudinal edges of the Hose age lobes provided as clips or clips act and the curved Fix the hose section in its position in the hose holder. Of the Hose can thus neither slip in the hose holder nor off emerge from the hose holder. With the hose holder according to the invention can hose bends in different, z. B. in 90 degrees entangled levels being represented. Thus, the curved tube section as joint between connecting pieces with different positions and different ones Axis alignment can be used. Particularly advantageous is the Use as a refrigerant hose section or connector in a refrigerant circuit an air conditioner for Motor vehicles. For this purpose, the hose ends with appropriate refrigerant connection pipes Mistake.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben. Es zeigenOne embodiment The invention is illustrated in the drawing and will be described below described in more detail. Show it
Für den Schlauchabschnitt
Durch diese erfindungsgemäße Kombination von Endlosschlauch und festem Schlauchhalter kann ein gekrümmter Schlauchabschnitt dargestellt werden, was zu reduzierten Herstellkosten führt.By this combination of Endless hose and fixed hose holder can be a curved hose section be represented, which leads to reduced production costs.
Abweichend von dem oben beschriebenen Ausführungsbeispiel ist die Erfindung auch für andere gekrümmte Schlauchverbindungen anwendbar, z. B. für Kühlmittelschläuche von Kühl- oder Heizungskreisläufe, für Kraftstoffleitungen oder für Bremsflüssigkeitsleitungen, jeweils in Kraftfahrzeugen.deviant from the embodiment described above the invention is also for other curved Hose connections applicable, z. B. for coolant hoses of Cooling or Heating circuits for fuel lines or for Brake fluid lines, each in motor vehicles.
