Abstract
Description
Die Erfindung betrifft einen speziell ausgeformtes Ende eines mehrlagigen Schlauchs aus profiliertem Bandmaterial. Das speziell ausgeformte Ende ermöglicht die einfache Montage des Schlauchs in ein Rohrleitungssystem, vorzugsweise in eine Abgasleitung für Kraftfahrzeuge.The The invention relates to a specially shaped end of a multilayer Hose made of profiled strip material. The specially shaped end allows the simple installation of the hose in a piping system, preferably in an exhaust pipe for Motor vehicles.
Mehrlagige
Schläuche
aus profiliertem Bandmaterial werden insbesondere im Nutzfahrzeugbereich
als Entkopplungselemente in Abgasanlagen eingesetzt. Zu deren Integration
in die Abgasanlage werden sowohl stoffschlüssige Verbindungen als auch
kraft- und formschlüssige
Verbindungen eingesetzt. Stoffschluß wird durch das Verschweißen des
Schlauchs erzielt. Hierzu werden die Schläuche zum Teil mit Innen- und
Außenringen
versehen, wie es beispielhaft in
Reibschlüssige Schellenverbindungen sind kosteneffektiver und variabler einsetzbar. Ihr Nachteil sind hohe Leckagewerte, die zugleich den Einsatz von reibschlüssigen Schellenverbindungen zukünftig in Frage stellen. Dies vor allem, da weltweite gesetzliche Vorschriften den Schadstoff-Ausstoß von PKW und Nutzfahrzeugen zukünftig deutlich nach unten regulieren. Eine verbleibende Restleckage, durch die nicht nachbehandeltes Abgas aus dem System entweichen kann, ist dann nur noch in eingeschränkter Form zulässig.Frictionally engaged clamp connections are more cost effective and variable in use. Your disadvantage is high leakage values, which at the same time the use of frictional clamp connections in future in Ask a Question. This especially since there are worldwide legal regulations the pollutant emissions of Passenger cars and commercial vehicles in the future clearly down regulate. A remaining residual leakage, through the untreated exhaust gas can escape from the system, is then only in limited form allowed.
Aufgabe der Erfindung ist es daher, den Endbereich eines mehrlagigen Schlauchs aus profiliertem Bandmaterial so auszubilden, dass der Schlauch ohne die Adaption weiterer Elemente direkt durch eine Schellenverbindung formschlüssig und mit sehr geringer Leckage in ein Leitungssystem integriert werden kann.task The invention therefore is the end region of a multi-layered hose made of profiled strip material so that the hose without the adaptation of further elements directly by a clamp connection form-fitting and be integrated into a piping system with very little leakage can.
Diese Aufgabe wird erfindungsgemäß durch eine im Anschlussbereich des Schlauches aufgeweitete und kalibrierte Geometrie gelöst.These The object is achieved by a expanded and calibrated in the connection area of the hose Geometry solved.
Zu diesem Zweck werden die zueinander beweglichen Wickellagen im umzuformenden Endbereich zueinander fixiert. Diese Fixierung erstreckt sich vom Schlauchende bis hin in den Bereich, in dem der Schlauch seinen ursprünglichen Durchmesser beibehält, um möglichst optimale Krafteinleitungsbedingungen bei einer Schwingbeanspruchung zu erzielen.To For this purpose, the mutually movable winding layers are to be reshaped Fixed end to each other. This fixation extends from Hose end up into the area where the hose its original Maintains diameter, as possible optimal force application conditions for a vibratory load too achieve.
In der Regel wird die Fixierung der Wickellagen zueinander mit einem mechanischen Kalibrierwerkzeug erzielt, welches die Luftspalte zwischen den einzelnen Wickellagen des Schlauchs minimiert und auf diese Weise die Beweglichkeit der Wickellagen zueinander einschränkt.In The rule is the fixation of the winding layers to each other with a achieved mechanical calibration tool, which the air gaps between the minimizes individual winding layers of the hose and in this way limits the mobility of the winding layers to each other.
Weiterhin ist auch das Tauchen der Schlauchendbereiche in eine aushärtende Dichtmasse möglich. Eine dritte Alternative zur Fixierung der Wickellagen ist das Setzen von Schweißpunkten oder aber Schweißnähten am Außenumfang des Wickelschlauchs, die entweder in axialer Richtung oder aber schraubengangförmig angebracht werden können.Farther it is also possible to immerse the hose end areas in a hardening sealant. A third alternative for fixing the winding layers is setting of welds or welds on the outer periphery of the winding tube, either in the axial direction or else helically can be attached.
Im
Anschluß an
das Fixieren der Bandlagen zueinander erfolgt die Umformung in die
Endkontur, welchen einen direkten Anschluß des Wickelschlauchs mittels
einer formschlüssigen
Schelle ermöglicht.
Zur Erzeugung einer glatten, gut dichtenden Oberfläche oder gleichermaßen zur Erhöhung der Dauerfestigkeit können in den aufgeweiteten Endbereich weitere, Elemente eingebracht werden. Diese sollen aus ökonomischen Gründen zunächst eine einfache geometrische Form aufweisen. Sie werden vor der Umformung des Schlauchendes aufgeschoben und mit dem Endbereich des Schlauchs zusammen umgeformt.to Creation of a smooth, good sealing surface or alike increase the fatigue strength can in the expanded end more, elements are introduced. These should be made of economic Initially a simple one have geometric shape. They are before the deformation of the hose end deferred and reshaped together with the end portion of the hose.
Die beschriebenen Varianten stellen die Möglichkeiten der Gestaltung des Endbereichs nur exemplarisch und nicht vollständig dar.The variants described represent the possibilities of design the end of only exemplary and not complete dar.
Neben dem Einsatz in den Abgasanlagen von Kraftfahrzeugen kann das beschriebene Anschlußende eines Wickelschlauchs gleichwohl in Industrieapplikationen, wie z.B. den Abgasanlagen stationärer Turbinen, Anwendung finden.Next the use in the exhaust systems of motor vehicles, the described terminal end a winding hose, however, in industrial applications, such as e.g. the exhaust systems stationary Turbines, find application.
