Abstract

The tube has a single tube profile including inner and outer metallic strip layers (11, 13). One of the strip layers is formed as a support layer, diffusion layer or insulating layers. The insulating layers are made of glass-like materials, textile E-glass, ceramic materials, stainless steel fibers, graphite fibers, aluminum oxide, precursor coated fabrics, pre-ceramic polymer in solid, paste or foam-like consistency, fiber reinforced fabrics and graphite tape, metal-fabric composites, needled-punched nonwovens, temperature-resistant support fibers and strength-enhancing stainless steel wires.

Description

Die Erfindung betrifft einen Schlauch, hergestellt durch schraubengangförmiges, mehrlagiges Wickeln von profiliertem Bandmaterial mit eingehakter oder aber agraffartiger Bindung der Wickellagen.The invention relates to a hose made by helical, multi-layer winding of profiled strip material with a hooked or agraffartiger binding of the winding layers.

Vor allem im PKW-Bereich, aber auch bei Nutzfahrzeugen sind solche Wickelschläuche als so genannte Liner zur Abgasführung in Entkopplungselementen von Abgasanlagen bekannt. Sie werden in gasdichte Metallbälge eingebracht, um zusätzliche Turbulenzen im Abgasstrom zu vermeiden und um gleichermaßen die thermischen und akustischen Isolationseigenschaften des Entkopplungselements zu verbessern.Especially in the passenger car sector, but also in commercial vehicles such winding tubes are known as so-called liners for the exhaust system in decoupling elements of exhaust systems. They are introduced into gas-tight metal bellows in order to avoid additional turbulence in the exhaust gas flow and also to improve the thermal and acoustic insulation properties of the decoupling element.

Im Nutzfahrzeugbereich werden Wickelschläuche oftmals alleine, d. h. mit Anschlusstechnik jedoch ohne umhüllenden Metallbalg als Entkopplungselement in den Abgasanlagen eingesetzt. Aufgrund einer zwar geringen, aber dennoch zulässigen Restleckage ist hier in vielen Fällen keine gasdichte Hülle erforderlich. Ein einfaches Ausführungsbeispiel für die als Entkopplungselement eingesetzten Metallschläuche ist der so genannte Agraff-Schlauch. Weitere Ausführungsbeispiele, die gegenüber dem Agraff-Schlauch noch geringere Abgas-Leckagen aufweisen, sind durch die Schriften DE 344 1064 C2 sowie DE 101 13 180 C2 bekannt geworden. Alle bekannten Ausführungsformen der Wickelschläuche sind in ihrer Endkontur mehrlagig, werden jedoch stets aus einem einlagig in den Fertigungsprozess einlaufendes, vorzugsweise ebenes, metallisches Band hergestellt.In the commercial vehicle sector winding tubes are often alone, ie used with connection technology but without enveloping metal bellows as a decoupling element in the exhaust systems. Due to a small but still permissible residual leakage, in many cases no gas-tight envelope is required here. A simple embodiment of the metal hoses used as a decoupling element is the so-called Agraff hose. Further exemplary embodiments, which have even lower exhaust gas leakages than the Agraff hose, are known from the documents DE 344 1064 C2 such as DE 101 13 180 C2 known. All known embodiments of the winding tubes are multi-layered in their final contour, but are always made of a single-layer in the manufacturing process incoming, preferably flat, metallic strip.

Da weltweite gesetzliche Vorschriften den Schadstoff-Ausstoß von Nutzfahrzeugen zukünftig deutlich nach unten regulieren, werden Abgasanlagen zukünftig vermehrt mit Nachbehandlungsmodulen wie z. B. Rußpartikel-Filtern und SCR-Systemen ausgestattet werden. Die Funktionsfähigkeit der Abgas-Nachbehandlungen ist in starker Maß von der Temperatur des Abgases abhängig, mit der es in die Nachbehandlung eintritt. Dies gilt im Fall der SCR-Systeme für die katalytische Reaktion, die möglichst kurz nach dem Startvorgang zu einer nahezu vollständigen Reduktion der Stickoxide führen soll. Im Fall des Partikelfilters kann die passive Regenerierung nur beim Überschreiten einer Mindest-Abgastemperatur erfolgen. Die aktive Regenerierung, die z. B. durch das Einspritzen von unverbranntem Diesel in die Abgasanlage initialisiert wird, arbeitet ebenfalls umso effektiver, je höher die Abgastemperaturen sind. Daraus ergibt sich die Forderung, dass die Temperaturverluste im Abgas von seinem Weg vom Turbo-Ausgang bis hin zum Eingang in die Nachbehandlung zu minimieren sind. Von dieser Forderung ist auch der Wickelschlauch betroffen, da er in beiden erwähnten Ausführungsformen, entweder als Liner-Element in Bälgen oder aber als alleiniges Entkopplungselement ohne umhüllenden Metallbalg fast ausschließlich im Abgasstrang zwischen Turbo-Ausgang und dem Eingang in die Nachbehandlung angeordnet ist. Somit ist auch der Temperaturverlust im Bereich des Wickelschlauchs zu minimieren.Since worldwide legal regulations regulate the pollutant emissions of commercial vehicles significantly downwards in the future, exhaust systems will in future increasingly with after-treatment modules such. As soot particle filters and SCR systems are equipped. The functionality of the exhaust aftertreatments is highly dependent on the temperature of the exhaust gas, with which it enters the aftertreatment. This applies in the case of the SCR systems for the catalytic reaction, which should lead to an almost complete reduction of the nitrogen oxides as soon as possible after the starting process. In the case of the particulate filter, passive regeneration can only take place when a minimum exhaust gas temperature is exceeded. The active regeneration z. B. is initialized by the injection of unburned diesel in the exhaust system, also works more effectively, the higher the exhaust gas temperatures. This results in the requirement that the temperature losses in the exhaust gas from its path from the turbo output to the input to the aftertreatment are to be minimized. From this requirement, the winding tube is affected because it is located in both mentioned embodiments, either as a liner element in bellows or as a sole decoupling element without enveloping metal bellows almost exclusively in the exhaust line between the turbo outlet and the entrance to the aftertreatment. Thus, the temperature loss in the winding tube is to minimize.

Vor diesem Hintergrund ist es Aufgabe der vorliegenden Erfindung, einen verbesserten Wickelschlauch bereitzustellen, der die Temperaturverluste im durchströmenden Abgas minimiert. Die Beibehaltung aller Funktionseigenschaften des Wickelschlauchs als Entkopplungs-Element, die Möglichkeit zur nicht beschädigenden äußerlichen Reinigung des Entkopplungselements unter zu Hilfenahme eines Dampfstrahlers sowie die Bereitstellung einer ökonomisch attraktiven Lösung sind Nebenaufgaben der Erfindung.Against this background, it is an object of the present invention to provide an improved winding tube, which minimizes the temperature losses in the flowing exhaust gas. The maintenance of all functional properties of the winding tube as a decoupling element, the possibility of non-damaging external cleaning of the decoupling element with the aid of a steam jet and the provision of an economically attractive solution are secondary tasks of the invention.

Hauptaufgabe sowie Nebenaufgaben werden durch einem Wickelschlauch mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen enthalten.Main task and secondary tasks are solved by a winding tube having the features of claim 1. Advantageous embodiments are contained in the subclaims.

Der erfindungsgemäße Wickelschlauch besteht aus profilierten metallischen und nichtmetallischen Bandlagen, die miteinander mehrlagig, schraubenförmig gewickelt sind. Im Gegensatz zu allen bisher bekannten Wickelschläuchen, bei denen stets ein einlagiges, ebenes Band in den Fertigungsprozess einläuft, wird beim Erfindungsgegenstand ein mehrlagig einlaufendes Band aus einer Kombination metallischer und nicht-metallischer Werkstoffe angewendet (1).The winding tube according to the invention consists of profiled metallic and non-metallic band layers which are wound together in a multi-layered, helical manner. In contrast to all hitherto known winding tubes, in which always enters a single-layer, flat band in the manufacturing process, a multi-layer incoming belt of a combination of metallic and non-metallic materials is used in the subject invention ( 1 ).

Das mehrlagig in den Wickelprozess einlaufende Band besteht in einer bevorzugten Ausführungsform aus drei Komponenten, wobei (11) ein metallischer Werkstoff, die mittlere Lage (12) ein Isolationswerkstoff und die Bandlage (13) wiederum ein metallischer Werkstoff ist. Auf diese Weise wird das Gleiten sowie die Reibung der Lagen zueinander auf die metallischen Kontaktpartner (11, 13) konzentriert. Die isolierende Mittellage (12) hat keine reibungsbehafteten Kontaktpunkte und arbeitet aufgrund dessen nahezu verschleißfrei.The multi-layer incoming in the winding process band consists in a preferred embodiment of three components, wherein ( 11 ) a metallic material, the middle layer ( 12 ) an insulating material and the band layer ( 13 ) is again a metallic material. In this way, the sliding and the friction of the layers to each other on the metallic contact partner ( 11 . 13 ). The insulating middle layer ( 12 ) has no frictional contact points and therefore works almost wear-free.

In bevorzugten Ausführungsformen kann das metallische Bandmaterial aus Edelstahl, insbesondere der Sorten 1.4301 und 1.4828 bestehen. Alternative metallische Werkstoffe können z. B. 1.4541, 1.4571, 1.4509, 1.4512 oder aber verzinkter bzw. aluminisierter Stahl sein.In preferred embodiments, the metallic strip material may consist of stainless steel, in particular of grades 1.4301 and 1.4828. Alternative metallic materials may, for. B. 1.4541, 1.4571, 1.4509, 1.4512 or galvanized or aluminized steel.

Der Aufbau aus drei Komponenten ermöglicht weiterhin, dass die innere metallische Lage (11) und die äußere metallische Lage (13) aus unterschiedlichen metallischen Werkstoffen bestehen können. Insbesondere im Hinblick auf die thermische Beanspruchung im Betrieb, und im Hinblick auf die Auswahl geeigneter Partner-Werkstoffe für den Reibkontakt, eröffnet die Anordnung Gestaltungsspielraum.The structure of three components also allows the inner metallic layer ( 11 ) and the outer metallic layer ( 13 ) may consist of different metallic materials. In particular, with regard to the thermal stress in the operation, and in terms of Selection of suitable partner materials for the frictional contact, the arrangement leaves room for maneuver.

Die isolierende Mittellage (12) besteht in bevorzugten Ausführungsformen aus typischen Isolationswerkstoffen mit glasartigen bzw. keramischen Anteilen, z. B. aus texturiertem E-Glas. Folgende weitere Stoffe sind beispielhaft, jedoch in der Aufzählung nicht abschließend für die isolierende Mittellage geeignet:

  • • Gewebe aus keramischen Fasern, temperaturbeständigen Trägerfasern und festigkeitssteigernden Edelstahldrähten.
The insulating middle layer ( 12 ) consists in preferred embodiments of typical insulating materials with vitreous or ceramic portions, z. B. made of textured E glass. The following further materials are exemplary but not exhaustive in the enumeration suitable for the insulating middle layer:
  • • Knitted elements made of stainless steel fibers and graphite fibers.

  • • Fiber-reinforced knitwear made of graphite tape.
  • • metal-textile composites
  • • Needle fleece
  • • Fabrics made of ceramic fibers, temperature-resistant carrier fibers and strength-enhancing stainless steel wires.

Ebenso ist es möglich, dass die Mittellage (12) keine eigenständige strukturelle Integrität aufweist, sondern als Beschichtung auf die metallischen Streifen (11) oder (13) aufgebracht wird.It is also possible that the middle layer ( 12 ) has no independent structural integrity, but as a coating on the metallic strip ( 11 ) or ( 13 ) is applied.

Ebenso können Kombinationen aus den genannten Materialien für spezielle Anwendungen besonders geeignet sein.Likewise, combinations of the materials mentioned may be particularly suitable for specific applications.

Weitere Ausführungsformen des isolierenden Wickelschlauchs sehen unterschiedliche Anzahlen und Kombinationen von metallischen und isolierenden Bandlagen vor, deren Anzahl in der beschriebenen, bevorzugten Ausführungsform drei beträgt. Neben dieser bevorzugten Form sind isolierende Wickelschläuche mit von zwei bis hin zu einer zweistelligen Anzahl von Bandlagen mit jeweiliger struktureller Integrität technisch realisierbar.Other embodiments of the insulating winding tube provide different numbers and combinations of metallic and insulating tape layers whose number in the described preferred embodiment is three. In addition to this preferred form, insulating winding tubes with from two to a two-digit number of band layers with respective structural integrity are technically feasible.
