Abstract
Verbindung zwischen dem Anschlußstutzen (2) eines Motorkühlers (1) und einem Kühlwasserrohr, mit einem Rohrstück (6) aus einem elastischen Material, das mit einem Ende über den Anschlußstutzen (2) geschoben und darauf mittels eines Sicherungselements (3) fixiert ist, und das mit dem anderen Ende das Ende des Kühlwasserrohrs übergreift und fest daran anliegt, dadurch gekennzeichnet, daß das Kühlwasserrohr als mehrschichtiges Kunststoffrohr (4) ausgebildet ist, und am vom Rohrstück (6) übergriffenen Ende des Kunststoffrohrs (4) eine innere Stützhülse (5) an der Innenwand des Kunststoffrohrs (4) anliegt, wobei diese innere Stützhülse (5) einen radial sich erstreckenden Flansch (5a) aufweist, der mit seinem äußeren Rand (5b) an der Innenwand des Rohrstücks (6) anliegt.Connection between the connecting piece (2) of an engine cooler (1) and a cooling water pipe, with a pipe section (6) made of an elastic material, which is pushed with one end over the connecting piece (2) and fixed thereon by means of a securing element (3), and which engages with the other end of the end of the cooling water pipe and lies firmly against it, characterized in that the cooling water pipe is designed as a multilayer plastic pipe (4), and an inner support sleeve (5) at the end of the plastic pipe (4) overlapped by the pipe section (6) abuts on the inner wall of the plastic tube (4), this inner support sleeve (5) having a radially extending flange (5a) which lies with its outer edge (5b) on the inner wall of the tube piece (6).
Description
Die Erfindung betrifft eine Verbindung zwischen dem Anschlußstutzen eines Motorkühlers und einem Kühlwasserrohr nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a connection between the connecting piece an engine cooler and a cooling water pipe according to the preamble of claim 1.
Kühlwasserrohre werden bisher in der Praxis nahezu ausschließlich als Gummischläuche ausgebildet. Diese Gummischläuche werden mit ihren Enden auf die Anschlußstutzen des Motorkühlers aufgeschoben und dort mittels eines Sicherungselements, beispielsweise einer Rohrschelle, fixiert.Cooling water pipes have so far been practically designed exclusively as rubber hoses. These rubber hoses are pushed with their ends onto the connecting piece of the engine cooler and there by means of a securing element, for example one Pipe clamp, fixed.
Verbindungen der im Oberbegriff als
bekannt vorausgesetzten Art sind bereits bekannt (
Es ist auch bereits bekannt, Kühlwasserrohre
aus Kunststoff auszubilden (
Bei allen Kühlwasserkreisläufen ist es erforderlich, daß diese überall gegen alle Kühlwasserzusätze beständig sein müssen. Diese Forderung besteht deshalb auch für die Verbindungsstelle zwischen dem handelsüblichen Anschlußstutzen und dem Kühlwasserrohr.With all cooling water circuits it is required that these be opposed everywhere all cooling water additives must be stable have to. This requirement therefore also applies to the liaison between the standard connecting branch and the cooling water pipe.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Verbindung zu schaffen, welche den einfachen und sicheren Anschluß eines aus Kunststoff bestehenden Kühlwasserrohres an einen üblich ausgebildeten Anschlußstutzen eines Motorkühlers erlaubt, wobei alle für Kühlwasserkreisläufe von der Automobilindustrie aufgestellten Forderungen eingehalten werden sollen.Based on this state of the art the invention has for its object to provide a connection which is the simple and safe connection of a plastic cooling water pipe to a common one trained connecting piece an engine cooler allowed, all for Cooling water circuits from demands made in the automotive industry are complied with should.
Die Lösung dieser Aufgabe erfolgt bei einer gattungsgemäßen Verbindung mit den Merkmalen des Kennzeichnungsteils von Anspruch 1.This task is solved with a generic connection with the features of the labeling part of claim 1.
Bevorzugte Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.Preferred configurations of the invention are in the subclaims described.
Das Kühlwasserrohr wird bei der erfindungsgemäßen Verbindung nicht direkt mit dem Anschlußstutzen des Motorkühlers verbunden, sondern unter Zwischenschaltung eines elastischen Rohrstutzens. Dieser elastische Rohrstutzen kann in der bekannten Weise auf den Anschlußstutzen aufgeschoben und über ein Sicherungselement darauf gesichert werden. Eine weitere Verbindungsstelle ist zwischen dem Ende des Kunststoffrohrs und dem freien Ende des Rohrstücks vorgesehen. Unter dem übergreifenden Ende des elastischen Rohrstücks ist am Ende des Kunststoffrohrs eine innere Stützhülse vorgesehen, die an der Stirnseite einen radial nach außen verlaufenden Flansch aufweist, der mit seinem äußeren Rand an der Innenwand des elastischen Rohrstücks anliegt.The cooling water pipe is in the connection according to the invention not directly with the connecting piece connected to the engine cooler, but with the interposition of an elastic pipe socket. This elastic pipe socket can in the known manner on the connection piece postponed and over a securing element can be secured on it. Another liaison is between the end of the plastic tube and the free end of the pipe section intended. Under the overarching End of the elastic pipe section an inner support sleeve is provided at the end of the plastic tube, which on the End face a radially outward Has flange, with its outer edge on the inner wall of the elastic pipe section is applied.
Nachstehend wird eine bevorzugte Ausführungsform der Erfindung anhand der Zeichnung im einzelnen beschrieben. Die Zeichnung zeigt einen Längsschnitt durch den oberen Bereich der Verbindung.Below is a preferred one embodiment the invention with reference to the drawing described in detail. The Drawing shows a longitudinal section through the top of the connection.
Die in der Zeichnung nur zur Hälfte dargestellten Elemente sind symmetrisch ausgebildet.Only half shown in the drawing Elements are symmetrical.
