Description

Die Erfindung betrifft eine flexible Schlauchleitung nach der im Oberbegriff von Anspruch 1 näher definier­ ten Art.The invention relates to a flexible hose line after the closer defined in the preamble of claim 1 ten Art.

Allgemein bekannt sind in der Luftführung eines Ver­ brennungsmotores flexible Luftschläuche. Diese haben die Aufgabe zwischen motorfesten und wagen festen Luft­ leitungen eine flexible Verbindung herzustellen. Die Falten eines derartigen Schlauches müssen dabei Rela­ tivbewegungen zwischen Motor und Karosserie aufnehmen können, d. h. sie müssen sich längs und quer verformen können.Are generally known in the air duct of a Ver internal combustion engine flexible air hoses. Have this the task between fixed and ventilated air lines to create a flexible connection. The Folding such a hose must rela Record active movements between the engine and body can, d. H. they have to deform lengthways and crossways can.

Schlauchleitungen dieser Art sind z. B. in "MTZ Motor­ technische Zeitschrift 45 (1984) 12, Seite 532 oder dem japanischen Abstract 62-48923 beschrieben.Hose lines of this type are e.g. B. in "MTZ Motor technical journal 45 (1984) 12, page 532 or Japanese abstract 62-48923.

Aus MTZ Motortechnische Zeitschrift 46 (1955) 10, Sei­ te 390 ist ein Turbolader und ein Ladeluftkühler be­ kannt, wobei zur Verbindung eine flexible Schlauchlei­ tung vorgesehen ist, die außenseitig mit einer gitter­ artigen Manschette überzogen ist. From MTZ Motortechnische Zeitschrift 46 (1955) 10, Sei te 390 is a turbocharger and an intercooler knows, for connecting a flexible hose device is provided on the outside with a grid like cuff is covered.  

Aus der DE-OS 28 19 328 ist ein flexibler Schlauch be­ kannt. Der Schlauch ist dabei mit Elementen versehen, die innen durch eine Schraubenfeder oder eine Ringver­ stärkung stabilisiert sind. Dieser vorbekannte Schlauch ist nicht als Druckleitung vorgesehen. Der Grund für die vorgesehene Drahteinlage liegt in einer variablen Formgebung der Schlauchverlegung, die ohne eine Drahtseele nicht möglich wäre. Ein langer unge­ stützter Schlauch würde sonst eine "Durchhängeform" annehmen. Durch die Schraubenfeder oder die Ringver­ stärkung wird der Schlauch vor einem Einfallen bzw. Einknicken bei engen Biegeradien geschützt. Die Ring­ verstärkungen sind dabei in die Schlauchwandung einge­ fügt (siehe Fig. 9).From DE-OS 28 19 328 a flexible hose is be knows. The hose is provided with elements the inside by a coil spring or a ring ver strengthening are stabilized. This previously known Hose is not intended as a pressure line. Of the The reason for the proposed wire insert lies in one variable shape of the hose routing without a wire soul would not be possible. A long time supported hose would otherwise have a "sag shape" accept. By the coil spring or the ring ver the hose is strengthened before Buckling protected in tight bend radii. The ring Reinforcements are inserted into the hose wall adds (see Fig. 9).

Bei einer flexiblen Schlauchleitung, die unter einem Innendruck steht, wie z. B. die Ladeluftleitung an ei­ nem aufgeladenen Verbrennungsmotor, besteht jedoch das Problem, daß unter einem derartigen Druck der Schlauch axial gelängt wird und dadurch die Falten eine Dehnung in Schlauchlängsrichtung erfahren. Durch eine derar­ tige Faltenverformung wird praktisch der Durchmesser der Falten kleiner. Dieses Längen des Schlauches führt dann zu Problemen bei Nachfolgebauteilen, z. B. an der wagenseitigen Lagerung eines Ladeluftkühlers.With a flexible hose line, which is under one Internal pressure, such as B. the charge air line to egg a supercharged internal combustion engine, however, there is Problem that under such pressure the hose is axially elongated and thereby the folds stretch experienced in the longitudinal direction of the hose. Through a derar Wrinkle deformation practically becomes the diameter the folds smaller. This lengthening of the hose leads then problems with successor components, e.g. B. at the car-side storage of an intercooler.

Der vorliegenden Erfindung liegt daher die Aufgabe zu­ grunde eine flexible Schlauchleitung der eingangs er­ wähnten Art, die unter Druck steht, derart auszubil­ den, daß sie zum einen genügend flexibel ist, um Re­ lativbewegungen aufnehmen zu können, aber zum anderen eine unerwünschte Längung durch den auf die Schlauch­ leitung wirkenden Druck so weit wie möglich einge­ schränkt wird. The present invention therefore has the object establish a flexible hose line at the beginning mentioned type that is under pressure to train in this way the one that it is flexible enough to Re to be able to record relative movements, but on the other hand an undesirable elongation due to the hose line pressure as far as possible is restricted.  

Erfindungsgemäß wird diese Aufgabe durch die im kenn­ zeichnenden Teil von Anspruch 1 genannten Merkmale ge­ löst.According to the invention, this task is characterized by the drawing part of claim 1 mentioned features ge solves.

Wie erwähnt, werden unter Druck die Durchmesser der Falten kleiner bzw. die Flanken der Falten werden fla­ cher, als Folge der axialen Längung des Schlauches. Die innenseitige ringförmige starre Einlage behindert nun eine derartige Durchmesserreduzierung, womit Län­ gendehnungen des Schlauches stark eingeschränkt wer­ den.As mentioned, the diameter of the Wrinkles become smaller or the flanks of the folds become fla cher, as a result of the axial elongation of the hose. The inner ring-shaped rigid insert hampers now such a diameter reduction, with which Län stretching of the hose severely restricted the.

Dabei wurde festgestellt, daß die für eine einwand­ freie Funktion des Schlauches erforderliche Flexibili­ tät jedoch erhalten bleibt. Dies gilt insbesondere in Längsrichtung auf Stauchung und in Querrichtung auf Biegung.It was found that the flawless free function of the hose required flexibility activity is retained. This is especially true in Longitudinal direction on upsetting and transverse direction Bend.

In den Unteransprüchen und in dem nachfolgend anhand der Zeichnung prinzipmäßig beschriebenen Ausführungs­ beispiel sind vorteilhafte Ausgestaltungen und Weiter­ bildungen der Erfindung aufgeführt.In the dependent claims and in the following based on the drawing execution described in principle Examples are advantageous refinements and further formations of the invention listed.

Eine flexible Schlauchleitung 1 ist in Abhängigkeit von der Schlauchlänge und den gestellten Anforderungen mit mehreren Falten 2 versehen, deren Außendurchmesser den Außenumfang der Schlauchleitung 1 überragt. Die Falten bilden - im Querschnitt gesehen - eine Wellen- bzw. Keilform mit schrägen Seitenflanken.Depending on the length of the hose and the requirements, a flexible hose line 1 is provided with a plurality of folds 2 , the outer diameter of which extends beyond the outer circumference of the hose line 1 . The folds - seen in cross section - form a wave or wedge shape with oblique side flanks.

Legt man nun innenseitig jeweils in die Falten 2 eine ringförmige starre Einlage, z. B. einen Drahtring 3 ein, so wird es beim Aufbau eines Druckes im Inneren der Schlauchleitung zu einer Reduzierung der Längung kommen, da die Falten sich in ihren Durchmessern damit nicht mehr reduzieren können.If you put the inside respectively in the folds 2, a rigid annular insert, z. B. a wire ring 3 , so there will be a reduction in elongation when building a pressure inside the hose line, since the folds can no longer reduce their diameters.

Wenn dabei die Drahtringe 3 derart in die Falten 2 eingelegt sind, daß sie mit ihren Außendurchmessern jeweils im Bereich der Innenwandung der Falten 2 mit deren größten Innendurchmessern anliegen, so werden Längendehnungen der Schlauchleitung noch stärker re­ duziert. Durch die direkte Anlage der starren Draht­ ringe an den Innenwandungen der Falten 2 haben diese praktisch überhaupt keine Möglichkeit zu einer Durch­ messerreduzierung.If the wire rings 3 are inserted into the folds 2 in such a way that their outer diameters lie in the area of the inner wall of the folds 2 with their largest inner diameters, the elongation of the hose line is reduced even more. Due to the direct contact of the rigid wire rings on the inner walls of the folds 2 , these have practically no possibility of a diameter reduction.
