Description
Die Erfindung betrifft einen Schwingungsdämpfer gemäß dem Oberbegriff von Patentanspruch 1.The The invention relates to a vibration damper according to the preamble of claim 1.

Des weiteren muss das Distanzteil aus einem schweißbaren Werkstoff bestehen, so dass zur Fertigung der konkaven Oberflächen ein spanendes Herstellungsverfahren eingesetzt werden muss. Zudem besteht die Schwierigkeit, beim Schweißen möglichst wenig Wärme in die Nähe des Distanzteils einzubringen, damit die Dichtmittel nicht beschädigt werden.Of Furthermore, the spacer must consist of a weldable material, so that for the production of the concave surfaces a machining production process must be used. In addition, there is the difficulty when welding as possible little heat in the vicinity of the spacer so that the sealants are not damaged.
Aufgabe der vorliegenden Erfindung ist es, eine preiswerte Verbindung zwischen einem Schwingungsdämpfer und einem externen Gehäuse zu schaffen.task The present invention is an inexpensive connection between a vibration damper and an external housing to accomplish.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die Halteverbindung zwischen dem Gehäuse und dem Zylinder durch mindestens eine von dem Distanzteil räumlich getrennt ausgeführte Verbindungsstrebe gebildet wird.According to the invention Task solved by that the retaining connection between the housing and the cylinder through at least one spatially separated from the spacer spatially connecting strut is formed.
Durch die funktionale Trennung der Funktionen Befestigen des Gehäuses am Zylinder und Bildung der Strömungsverbindung besteht nicht mehr die Anforderung an das Distanzteil der Schweißbarkeit. Des weiteren kann der Abstand zwischen den Schweißstellen an der Verbindungsstrebe zu Dichtungen im Bereich des Distanzteils deutlich vergrößert und damit die Wärmeeinleitung reduziert werden. Dadurch können wiederum einfachere Dichtungswerkstoffe verwendet werden.By the functional separation of the functions attaching the housing on Cylinder and formation of the flow connection there is no longer the requirement for the spacer part of the weldability. Furthermore, the distance between the welds at the connecting strut to seals in the area of the spacer clearly enlarged and thus the heat introduction be reduced. Thereby can in turn, simpler sealing materials can be used.
Die Verbindungsstreben sollen eine möglichst einfach Geometrie aufweisen. Deshalb ist die mindestens eine Verbindungsstrebe achsparallel zum Zylinder ausgerichtet. Folglich kann ein einfaches streifenförmiges Blechteil für die Verbindungsstrebe zur Anwendung kommen.The Connecting struts should be as possible simply have geometry. Therefore, the at least one connecting strut aligned axially parallel to the cylinder. Consequently, a simple strip-shaped Sheet metal part for the connecting strut are used.
In weiterer vorteilhafter Ausgestaltung weist die Verbindungsstrebe randseitige Freischnitte auf, so dass begrenzte Anlageflächen zu dem Gehäuse und/oder dem Zylinder vorliegen. Diese Maßnahme dient zur Gewichtseinsparung aber auch um die Auftragung des Lacks zwischen dem Gehäuse und dem Zylinder zu vereinfachen.In Another advantageous embodiment has the connecting strut marginal cutouts on, allowing limited contact surfaces too the housing and / or the cylinder present. This measure is used to save weight but also to the application of the paint between the housing and to simplify the cylinder.
Gemäß einem vorteilhaften Unteranspruch weist das Distanzteil einen Führungsansatz aufweist, der in eine Durchgangsöffnung des Zylinders und/oder des Gehäuses eingreift. Damit wird im Vergleich zum Stand der Technik ein Bauteil eingespart und die Montage vereinfacht.According to one advantageous subclaim, the spacer has a guide approach having, in a through hole of the cylinder and / or the housing intervenes. This is compared to the prior art, a component saved and simplified assembly.
Um den Fertigungsaufwand zu minimieren besteht das Distanzteil aus einem spritzfähigen Kunststoff besteht. Es lassen sich auch kompliziertere Oberflächen sehr passgenau herstellen.Around to minimize the production costs consists of the spacer a sprayable plastic consists. It can also be more complicated surfaces very much make perfect fit.
Das Distanzteil weist im Bereich der Kontaktflächen zum Gehäuse und/oder Zylinder Nuten für Dichtmittel auf. Alternativ können die Dichtmittel auch direkt von dem Distanzteil gebildet werden.The Spacer has in the region of the contact surfaces to the housing and / or Cylinder grooves for sealant on. Alternatively you can the sealing means are also formed directly from the spacer.
Im Hinblick auf eine prozesssichere Fertigung ist das Distanzteil zur unverwechselbaren Einbaulage mit formschlüssig wirkenden Orientierungsflächen ausgeführt, die in entsprechende Gegenflächen am Zylinder und/oder Gehäuse eingreifen.in the With regard to reliable production, the spacer is for unmistakable mounting position designed with positively acting orientation surfaces, the in corresponding mating surfaces on the cylinder and / or housing intervention.
Besonders einfach können die Gegenflächen erreicht werden, wenn diese am Zylinder und/oder Gehäuse von einer Durchgangsöffnung der Strömungsverbindung gebildet werden.Especially just can the mating surfaces be achieved if this on the cylinder and / or housing of a passage opening the flow connection be formed.
Dazu weist die Durchgangsöffnung am Zylinder eine maßliche Abweichung zur Durchgangsöffnung im Gehäuse auf. Beispielsweise wird der Rand der Durchgangsöffnung so profiliert, dass ein schneller Blick genügt, um die richtige Kontaktfläche zum Zylinder oder Gehäuse auszurichten.To has the passage opening on the cylinder a dimensional Deviation from the passage opening in the case on. For example, the edge of the passage opening is profiled so that a quick look is enough for the right contact surface to the cylinder or housing align.
Des weiteren kann vorgesehen sein, dass die Verbindungsstrebe in radiale Richtung von mindestens zwei miteinander verbundenen Einzelstreben gebildet wird. Der große Vorteil besteht darin, dass man jeweils eine Einzelstrebe am Gehäuse und dem Zylinder anschweißen kann, ohne dass das Distanzteil montiert sein muss. Am Ende des Montageprozesses werden die Einzelstreben miteinander verbunden, z.B. verschweißt, wobei der räumliche Abstand zu den Distanzteilen so groß ist, dass keine Wärmeeinwirkung an den Dichtungen innerhalb der Distanzteile festzustellen ist.Of Further it can be provided that the connecting strut in radial Direction of at least two interconnected individual struts is formed. The great Advantage is that in each case a single strut on the housing and the Weld cylinder can, without the spacer must be mounted. At the end of Assembly process, the individual struts are interconnected, e.g. welded, being the spatial Distance to the spacers is so great that no heat is noted at the seals within the spacers.
Die Einzelverbindungsstreben können aus einem rostfreien Werkstoff bestehen, so dass die angeschweißten Einzeltstreben jeweils zusammen mit dem Gehäuse oder dem Zylinder z.B. durch einen Lack oder eine andere Oberflächenbeschichtung gegen Korrosion geschützt werden. Anschließend verschweißt man die Einzelstreben, wobei diese Schweißnaht keine Rostvorsorge bedarf. Ggf. kann man den vorgesehenen Schweißbereich vor der Oberflächenbeschichtung oder Lackierung durch geeignete Maßnahmen abdecken, um die Schweißnaht zwischen den Einzelstreben nicht zu beeinträchtigen.The Individual connection struts can Made of a stainless material, so that the welded individual struts each together with the housing or the cylinder e.g. through a paint or other surface coating protected against corrosion become. Subsequently welded the individual struts, this weld does not require rust prevention. Possibly. you can the intended welding area before the surface coating or paint by suitable measures to cover the weld between not to affect the individual struts.
