Abstract
Description
Die Erfindung betrifft eine Schlaucharmatur nach dem Oberbegriff des Anspruchs 1.The invention relates to a hose fitting according to the Preamble of claim 1.
Aus der DE-PS 12 56 975 ist eine derartige Schlauchar matur bekannt. Sie sind in der Praxis bewährt und in vielen Fahrzeugen bei der Brems- und Kupplungshydrau lik im Einsatz. In neuerer Zeit werden immer mehr Fahrzeuge mit Antiblockiersystemen ausgerüstet. Dabei wird, wenn die Elektronik eine Blockiergefahr erkennt, der Druck im Bremssystem reduziert und wieder aufge baut, wenn die Blockiergefahr nicht mehr besteht. Dies kann bis zu 8mal je Sekunde erfolgen. Auf dem Prüf stand hat sich dabei gezeigt, daß bei den hohen Drücken und Pulsationen die Schlaucharmatur undicht wird.From DE-PS 12 56 975 such a hose is maturity known. They are tried and tested in practice many vehicles with the brake and clutch hydraulic lik in action. In recent times there are more and more Vehicles equipped with anti-lock braking systems. Here if the electronics detect a risk of locking, the pressure in the brake system is reduced and then restored builds when the risk of blocking no longer exists. This can be done up to 8 times per second. On the test stand has shown that the high Press and pulsation leaks the hose fitting becomes.
Es ist deshalb Aufgabe der Erfindung, die bewährte Schlaucharmatur der eingangs genannten Art so weiter zuentwickeln, daß mit einfachen Mitteln auch bei hohen Drücken und Pulsationen die Schlaucharmatur dicht bleibt.It is therefore an object of the invention, the proven Hose fitting of the type mentioned in the beginning develop that with simple means even at high Press and pulsations tightly the hose fitting remains.
Die Lösung der Aufgabe gelingt mit dem im kennzeich nenden Teil des Anspruchs 1 bzw. 2 angegebenen Merk mal. Durch den Versatz der Einzugssegmente in axialer bzw. in Umfangsrichtung bzw. deren Kombination ergibt sich vermutlich durch die dabei auftretende Labyrinth wirkung der versetzten Einzugsegmente überraschend eine hohe und zuverlässige Dichtheit der Schlaucharma tur. Weiterhin erfolgt eine homogene Pressung des Schlauchmaterials und eine Vermeidung von undefinier ten Seelenmaterialeinschnürungen.The task is solved with the in the characteristic nenden part of claim 1 or 2 specified note times. Due to the offset of the feed segments in the axial or in the circumferential direction or their combination probably through the resulting maze effect of the offset feed segments surprising a high and reliable tightness of the hose arm door. Furthermore, a homogeneous pressing of the Hose material and avoidance of undefined constricted soul material.
Die Erfindung soll an einem Ausführungsbeispiel erläu tert werden.The invention is to be explained using an exemplary embodiment be tert.
Fig. 1 zeigt eine Schlauchendarmatur mit axialem Ver satz der Einzugssegmente. Fig. 1 shows a hose end fitting with axial Ver set of the feed segments.
Fig. 2 zeigt eine Schlauchendarmatur mit in Umfangs richtung versetzten Einzugssegmenten. Fig. 2 shows a hose end fitting with feed segments offset in the circumferential direction.
In Fig. 1 ist der Schlauch mit 1 bezeichnet. An sei nem Ende ist die Schlaucharmatur 2 angeordnet, die in ihrer Bohrung einen Nippel 3 aufweist. Das Schlauchende ist zwischen dem Nippel 3 und dem Hülsen ansatz 4 der Schlaucharmatur 2 eingespannt und durch segmentweise Radialeinpressung unter Einschnürung des Hülsenansatzes 4 druckdicht befestigt. Die sich bei der Kaltverformung ergebenden benachbarten Einzugsseg mente 5 sind axial gegeneinander versetzt.In Fig. 1 the hose is designated 1 . At its end, the hose fitting 2 is arranged, which has a nipple 3 in its bore. The end of the hose is clamped between the nipple 3 and the sleeve attachment 4 of the hose fitting 2 and is pressure-tightly secured by segmental radial press-in, constricting the sleeve attachment 4 . The resulting Einzugsseg elements 5 resulting from the cold deformation are axially offset from one another.
In Fig. 2 ist eine Schlaucharmatur gezeigt, bei der zwei Reihen von Einzugssegmenten 5 nebeneinander ange ordnet sind und die eine Reihe gegenüber der anderen Reihe in Umfangsrichtung versetzt ist.In Fig. 2, a hose fitting is shown in which two rows of feed segments 5 are arranged side by side and one row is offset in the circumferential direction from the other row.
Der Versatz in Umfangsrichtung beträgt vorzugsweise eine halbe Breite der Einzugssegmente 5.The circumferential offset is preferably half a width of the feed segments 5 .
Schließlich können innerhalb einer Reihe die Einzugs segmente 5 auch noch axial gegeneinander versetzt sein.Finally, the feed segments 5 can also be axially offset from one another within a row.
