Mit innerhalb des jeweiligen Leitungsteiles angeordnet ist hier gemeint, dass das Verbindungsmittel jeweils mit Teilen in der Öffnung, sprich der durch die Schlauchhülle der jeweiligen Rohrleitung umschlossenen Durchgangsöffnung oder - bohrung, angeordnet ist. Die Leitungsteile sind insbesondere aus einem flexiblen Kunststoff gefertigt.This problem is solved by a pipeline, in particular hydraulic line of a hydraulic system of a motor vehicle, comprising a first conduit part and a second conduit part, wherein the second conduit part is inserted in a connecting region in the first conduit part, wherein in the connection region a connecting means is arranged partially is disposed within the second line part and partially within the first line part. With arranged within the respective conduit part is meant here that the connecting means in each case with parts in the opening, that is, the through the tubular casing of the respective pipe enclosed passage opening or - bore, is arranged. The line parts are made in particular of a flexible plastic.
Das Verbindungsmittel umfasst vorzugsweise ein Anschlussstück, das teilweise in den zweiten Leitungsteil eingeschoben ist. Dieses wiederum umfasst vorzugsweise einen Dichtkegelnippel zur reibschlüssigen und/oder formschlüssigen Verbindung mit dem zweiten Lei- tungsteil. Der Außendurchmesser des zweiten Leitungsteiles wird vorzugsweise in mindestens einem Teilbereich, in dem der Dichtkegelnippel angeordnet ist, durch diesen aufgeweitet, so- dass in Einbaulage eine Presspassung zwischen dem ersten und dem zweiten Leitungsteil in dem Teilbereich bewirkt wird.The connecting means preferably comprises a connecting piece which is partially inserted into the second conduit part. This in turn preferably comprises a sealing cone nipple for the frictional and / or positive connection with the second line. processing part. The outer diameter of the second conduit part is preferably widened in at least one subregion in which the sealing cone nipple is arranged, so that in the installed position an interference fit between the first and the second conduit part in the subregion is effected.
Das Verbindungsmittel weist vorzugsweise ein Kopfstück auf, der an einem Leitungsende des zweiten Leitungsteiles aus diesem herausragt, wobei das Kopfstück einen sich von einer Stirnseite zu dem Leitungsende hin vergrößernden Durchmesser aufweist. Das Kopfstück dazu ist vorzugsweise kugelabschnittförmig oder alternativ beispielsweise kegelstumpfförmig ausgebildet. Diese Gestalt ermöglicht eine leichte Zentrierung während der Montage.The connecting means preferably has a head piece, which protrudes at a line end of the second line part of this, wherein the head piece has an increasing from an end face to the line end diameter. The head piece for this purpose is preferably spherical segment-shaped or alternatively, for example, frusto-conical. This shape allows easy centering during assembly.
Der größte Außendurchmesser des Kopfstückes ist vorzugsweise größer als der Außendurchmesser des sich an das Kopfstück anschließenden zweiten Leitungsbereiches. Dadurch wird eine haltbare und druckdichte Presspassung zwischen Kopfstück und zweitem Leitungsteil bewirkt.The largest outer diameter of the head piece is preferably larger than the outer diameter of the adjoining the head piece second line region. As a result, a durable and pressure-tight interference fit between the head piece and the second line part is effected.
Das eingangs genannte Problem wird auch gelöst durch ein Verfahren zur Verbindung eines ersten Leitungsteiles mit einem zweiten Leitungsteil, wobei der zweite Leitungsteil in einem Verbindungsbereich in den ersten Leitungsteil eingeschoben ist, wobei zunächst ein Anschlussstück in ein Leitungsende des zweiten Leitungsteils eingeführt wird und danach der zweite Leitungsteil mit dem daran angeordneten Anschlussstück in ein Leitungsende des ersten Leitungsteiles eingeführt wird.The above-mentioned problem is also solved by a method for connecting a first line part to a second line part, wherein the second line part is inserted in a connection area in the first line part, wherein first a connector is inserted into a line end of the second line part and then the second Conduction part is introduced with the connecting piece arranged thereon in a line end of the first line part.
Im Folgenden werden Ausführungsbeispiele der Erfindung anhand der beiliegenden Zeichnungen erläutert. Dabei zeigen:In the following, embodiments of the invention will be explained with reference to the accompanying drawings. Showing:
Fig. 1 einen Schnitt durch ein Ausführungsbeispiel einer erfindungsgemäßen Rohrleitung;1 shows a section through an embodiment of a pipe according to the invention.
Fig. 2 den zweiten Leitungsteil und das Verbindungsmittel vor der Montage;Figure 2 shows the second conduit part and the connecting means prior to assembly.

Fig. 1 zeigt einen Schnitt durch ein Ausführungsbeispiel einer erfindungsgemäßen Rohrleitung 1. Die Rohrleitung 1 umfasst einen ersten Leitungsteil 2 und einen zweiten Leitungsteil 3, die in einem Verbindungsbereich 4 miteinander verbunden sind. Die Verbindung des ersten Leitungsteils 2 mit dem zweiten Leitungsteil 3 geschieht dergestalt, dass ein Leitungsende 6 des zweiten Leitungsteils 3 in ein Leitungsende 5 des ersten Leitungsteils 2 eingeschoben wird. Zur Sicherung der Verbindung gegen Herausziehen und zur Erhöhung der Druckdichtigkeit ist ein Verbindungsmittel 7 in dem Verbindungsbereich 4 angeordnet.Fig. 1 shows a section through an embodiment of a pipe according to the invention 1. The pipe 1 comprises a first pipe part 2 and a second pipe part 3, the are connected together in a connection region 4. The connection of the first line part 2 with the second line part 3 is done in such a way that a line end 6 of the second line part 3 is inserted into a line end 5 of the first line part 2. To secure the connection against pulling out and to increase the pressure tightness, a connecting means 7 is arranged in the connecting region 4.
Fig. 2 zeigt den zweiten Leitungsteil 3 und das Verbindungsmittel 7 vor der Montage, Fig. 3 zeigt das mit dem zweiten Leitungsteil 3 vormontierte Verbindungsmittel 7 vor der Montage mit dem ersten Leitungsteil 2. Bei den beiden Leitungsteilen 2 und 3 handelt es sich um flexible Kunststoffschläuche, wobei der Außendurchmesser des zweiten Leitungsteils 3 in etwa dem Innendurchmesser des ersten Leitungsteils 2 entspricht. Im Idealfall sind der Außendurchmesser des zweiten Leitungsteils 3 und der Innendurchmesser des ersten Leitungsteils 2 so gewählt, dass eine Übergangspassung oder Presspassung zwischen beiden hergestellt wird. Um beim Einschieben des Leitungsendes 6 des zweiten Leitungsteils 3 in das Leitungsende 5 des ersten Leitungsteils 2 eine höhere Festigkeit der Verbindung zu bewirken, damit ist insbesondere gemeint, eine höhere Zugfestigkeit vor einem Herausziehen des zweiten Leitungsteils 3 aus dem ersten Leitungsteil 2 und damit auch einhergehend eine höhere Druckbelastbarkeit und Dichtigkeit der beiden Verbindungen, ist das Verbindungsmittel 7 vorgesehen. Dieses umfasst ein Anschlussstück 8 und ein Kopfstück 9. Das Anschlussstück 8 ist in Einbaulage in den zweiten Leitungsteil 3 eingeschoben, das Kopfstück 9 ragt in Einbaulage aus dem Leitungsende 6 des zweiten Leitungsteils 3 heraus, wie dies aus Fig. 3 erkennbar ist. Das Anschlussstück 8 weist einen Dichtkegelnippel 10 zum Herstellen einer reibschlüssigen und/oder formschlüssigen Verbindung mit dem zweiten Leitungsteil auf. Der Dichtkegelnippel 10 umfasst dazu einen oder mehrere kegelstumpfförmige Bereiche 11 , deren größter Außendurchmesser DAmax größer ist als der Innendurchmesser DI3 des zweiten Leitungsteils 3 und deren kleinster Außendurchmesser DAmin kleiner ist als der größte Außendurchmesser DAmax und gleich oder geringfügig größer als der Innendurchmesser DI3 des zweiten Leitungsteils 3 ist. Ein dem Kopfstück 9 abgewandter Einführkegel 12 des Verbindungsmittels 7 ist ke- gelstumpfförmig gestaltet und hat einen kleinsten Außendurchmesser DA12min, der kleiner ist als der Innendurchmesser DI3 des zweiten Leitungsteils 3 und als Einführ- und Montagehilfe dient. Das Kopfstück 9 ist im vorliegenden Ausführungsbeispiel kugelabschnittförmig ausgebildet und kann alternativ beispielsweise kegelstumpfförmig oder dergleichen ausgebildet sein. Hier sind aber auch andere Geometrien möglich, bei denen sich der Außendurchmesser von einem Minimaldurchmesser D9min an einer Stirnseite 13 zu einem Maximaldurchmesser D9max verändert. Der Minimaldurchmesser D9min ist kleiner als der Innendurchmesser des ersten Leitungsteils 2 und dient als Montagehilfe zum Einführen der aus dem zweiten Lei- - A - tungsteil 3 und dem Verbindungsmittel 7 vormontierten Baugruppe. Der Maximaldurchmesser D9max des Kopfstückes 9 ist so gewählt, dass dieser auf das Anschlussstück 8 aufgeschoben im zweiten Leitungsteil 3 größer ist als der Außendurchmesser des zweiten Leitungsteils 3 im Bereich des Leitungsendes 6, das in der Einbaulage an das Kopfstück 9 anstößt.Fig. 2 shows the second conduit part 3 and the connecting means 7 prior to assembly, Fig. 3 shows the pre-assembled with the second conduit part 3 connecting means 7 prior to assembly with the first conduit part 2. The two line parts 2 and 3 are flexible Plastic hoses, wherein the outer diameter of the second conduit part 3 corresponds approximately to the inner diameter of the first conduit part 2. Ideally, the outer diameter of the second conduit part 3 and the inner diameter of the first conduit part 2 are chosen so that a transition fit or interference fit between them is produced. In order to effect a higher strength of the connection when inserting the line end 6 of the second line part 3 into the line end 5 of the first line part 2, this means, in particular, a higher tensile strength before pulling out the second line part 3 from the first line part 2 and thus also along a higher compressive strength and tightness of the two compounds, the connecting means 7 is provided. This comprises a connecting piece 8 and a head piece 9. The connecting piece 8 is inserted in the installed position in the second conduit part 3, the head piece 9 protrudes in the installed position from the conduit end 6 of the second conduit part 3, as can be seen from Fig. 3. The connecting piece 8 has a Dichtkegelnippel 10 for producing a frictional and / or positive connection with the second conduit part. The Dichtkegelnippel 10 includes for this purpose one or more frustoconical regions 11, the largest outer diameter DAmax is greater than the inner diameter DI3 of the second conduit part 3 and their smallest outer diameter DAmin is smaller than the largest outer diameter DAmax and equal to or slightly larger than the inner diameter DI3 of the second conduit part 3 is. An insertion cone 12, facing away from the head piece 9, of the connecting means 7 is configured as a truncated cone and has a smallest outer diameter DA12min which is smaller than the inner diameter DI3 of the second conduit part 3 and serves as an insertion and assembly aid. The head piece 9 is formed in the present embodiment spherical segment-shaped and may alternatively be formed, for example, frusto-conical or the like. However, other geometries are also possible here in which the outside diameter changes from a minimum diameter D9min on an end face 13 to a maximum diameter D9max. The minimum diameter D9min is smaller than the inner diameter of the first line part 2 and serves as an assembly aid for introducing the second line - A - part 3 and the connecting means 7 pre-assembled module. The maximum diameter D9max of the head piece 9 is chosen so that it is pushed onto the connecting piece 8 in the second conduit part 3 is greater than the outer diameter of the second conduit part 3 in the region of the conduit end 6, which abuts in the installation position on the head piece 9.
Die Fig. 2 und 3 verdeutlichen die Montage der Rohrleitung 1. Zunächst wird das Verbindungsmittel 7 in den zweiten Leitungsteil 3 eingefügt, man erhält die in Fig. 3 links dargestellte Zwischenstufe, bei der das Leitungsteil 3 an einem Leitungsende 6 das Verbindungsmittel 7 aufweist. In einem nächsten Schritt wird diese vormontierte Zwischenbaugruppe in das Leitungsende 5 des ersten Leitungsteils 2 eingeschoben, die fertig montierte Verbindung der beiden Leitungsteile und damit die fertig montierte Rohrleitung ist als Ausschnitt in Fig. 2 dargestellt. 2 and 3 illustrate the assembly of the pipeline 1. First, the connecting means 7 is inserted into the second conduit part 3, one obtains the intermediate shown in Fig. 3 on the left, in which the conduit part 3 at one end of the line 6, the connecting means 7. In a next step, this preassembled intermediate module is inserted into the line end 5 of the first line part 2, the finished assembled connection of the two line parts and thus the fully assembled pipe is shown as a detail in Fig. 2.
