Abstract
Speicher mit einem Gasbag, insbesondere für einen Schwingungsdämpfer, umfassend einen Hüllkörper, der in einem Gehäuse angeordnet ist und mehrere Gasbagabschnitte aufweist, über die der Gasbag einer äußeren Gehäusewandung des Speichers in seiner Form und/oder seiner Lage anpassbar ist, wobei der Speicher mindestens einen formbildenden Führungskörper aufweist, der zwei benachbarte Gasbagabschnitte zueinander abstützt.Storage device with a gasbag, in particular for a vibration damper, comprising an enveloping body which is arranged in a housing and has a plurality of gasbag sections, by means of which the gasbag can be adapted to an outer housing wall of the reservoir in its shape and / or position, wherein the reservoir has at least one Form-forming guide body which supports two adjacent gas bag sections to each other.
Description
Die Erfindung betrifft einen Schwingungsdämpfer mit einem Gasbag entsprechend dem Oberbegriff von Patentanspruch 1. The invention relates to a vibration damper with a gasbag according to the preamble of
Aus der
Für eine definierte Raumform des Gasbags werden bevorzugt axiale Verbindungen ausgeführt, die den Gasbag in einzelne Kissen unterteilen. Die axialen Verbindungen werden von Schweißnähten gebildet. Dadurch kann der Gasbag im Bereich der Verbindungen leicht einem gekrümmten Bauraum angepasst werden. For a defined spatial shape of the gas bag axial connections are preferably carried out, which divide the gas bag into individual pillows. The axial connections are formed by welds. As a result, the gasbag in the region of the connections can be easily adapted to a curved space.
In der Ausführung nach
Die Aufgabe der vorliegenden Erfindung besteht darin, ein möglichst großes Volumen über eine Gasbaganordnung zu realisieren. The object of the present invention is to realize the largest possible volume via a gas bag arrangement.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass der Speicher mindestens einen formbildenden Führungskörper aufweist, der zwei benachbarte Gasbagabschnitte zueinander abstützt. According to the invention the object is achieved in that the memory has at least one shape-forming guide body which supports two adjacent gas bag sections to each other.
Der große Vorteil der Erfindung besteht darin, dass der Gasbag nicht nur einlagig wie Stand der Technik, sondern auch mehrlagig ausgeführt sein kann. Dadurch kann das Volumen des Speichers deutlich besser ausgenutzt werden. Der Führungskörper vereinfacht die Montage und zwingt den Gasbag in eine vorbestimmte Einbauform. The great advantage of the invention is that the gas bag can be designed not only single-layered as the prior art, but also multi-layered. As a result, the volume of the memory can be significantly better utilized. The guide body simplifies the assembly and forces the gas bag in a predetermined installation form.
In weiterer Ausgestaltung ist vorgesehen, dass sich der Führungskörper radial an der Gehäusewandung des Speichers abstützt. Damit ist gewährleistet, dass die vorbestimmte Einbauform auch in der Einbausituation im Speicher erhalten bleibt. Eine vorbestimmte Einbauposition hat grundsätzlich den Vorteil, dass man die Belastung auf den Gasbag exakt vorbestimmen kann und damit den Gasbag für den Belastungsfall auslegen kann. In a further embodiment, it is provided that the guide body is supported radially on the housing wall of the memory. This ensures that the predetermined installation form is maintained even in the installation situation in the memory. A predetermined installation position basically has the advantage that one can exactly predetermine the load on the gas bag and thus interpret the gas bag for the load case.
Gemäß einem vorteilhaften Unteranspruch weist der Führungskörper mindestens zwei Führungsstege auf, die über einen Stützsteg miteinander verbunden sind, wobei sich der Stützsteg an der Gehäusewandung abstützt. Die Verbindung von mindestens zwei Führungsstegen versteift die gesamte Gasbaganordnung. According to an advantageous embodiment, the guide body has at least two guide webs, which are connected to one another via a support web, wherein the support web is supported on the housing wall. The connection of at least two guide webs stiffens the entire gasbag assembly.
Vorteilhafterweise weist der Führungssteg endseitig bezogen auf seine radiale Ausdehnung ein aufgerolltes Endprofil auf. Dadurch kann gezielt ein Biegeradius zwischen zwei benachbarten Gasbagabschnitten vorgegeben werden. Advantageously, the guide web has a rolled-up end profile with respect to its radial extent at the end. As a result, a bending radius between two adjacent gasbag sections can be predetermined.
Bei einer weiteren Ausführungsform wird der Führungskörper von einem längsgeschlitztes Rohr mit einem c-förmigen Querschnitt gebildet, dessen Innen- und/oder Außendurchmesser eine Führungsfläche bilden. Der Längsschlitz unterstützt eine Federwirkung des Führungskörpers zum Gasbag. In a further embodiment, the guide body is formed by a longitudinally slotted tube with a c-shaped cross-section, the inner and / or outer diameter of which form a guide surface. The longitudinal slot supports a spring action of the guide body to the gas bag.
Insbesondere bei einem längsgeschlitzten Rohr als Führungskörper bietet es sich an, wenn der Gasbag spiralförmig im Führungskörper angeordnet ist. Der Schlitz im Rohr dient als Übergang zwischen den Spiralabschnitten. In particular, in a longitudinally slotted tube as a guide body, it makes sense if the gas bag is arranged spirally in the guide body. The slot in the tube serves as a transition between the spiral sections.
Die Montage eines spiralförmigen Gasbags wird entscheidend vereinfacht, wenn der Führungskörper eine nach radial außen aufgeweitete Reduzierschräge für die Spiralformbildung des Gasbags aufweist. Der Gasbag gleitet selbständig in den nächsten Spiralabschnitt, da sich die Enden des Gasbags nicht verklemmen können. The mounting of a spiral gas bag is significantly simplified if the guide body has a radially outwardly flared Reduzierschräge for the spiral formation of the gas bag. The gas bag automatically slides into the next spiral section as the ends of the gas bag can not jam.
Im Hinblick auf eine Minimierung der Faltenbildung ist es vorteilhaft, wenn der Gasbag im radial äußeren Bereich des Speichers eine größere radiale Breite aufweist als im radial inneren Bereich des Speichers. With a view to minimizing the formation of wrinkles, it is advantageous for the gasbag to have a greater radial width in the radially outer region of the accumulator than in the radially inner region of the accumulator.
Insbesondere bei einem Speicher in einem Schwingungsdämpfer ist es vorteilhaft, wenn der Führungskörper aus einem wärmeleitfähigen Werkstoff besteht und damit die Wärmabfuhr aus dem Schwingungsdämpfer fördert. In particular, in a memory in a vibration damper, it is advantageous if the guide body consists of a thermally conductive material and thus promotes heat dissipation from the vibration damper.
Optional wird die Gehäusewandung von einem Rohrkörper gebildet, der zumindest bereichsweise eine radiale Eindrückung aufweist, über die der Gasbag in Umfangsrichtung verdrehgesichert ist. Insbesondere im Bereich der Enden des Gasbags wird eine konstante Breite des Gasbags erreicht. Optionally, the housing wall is formed by a tubular body which, at least in regions, has a radial indentation over which the gas bag is secured against rotation in the circumferential direction. In particular, in the region of the ends of the gas bag, a constant width of the gas bag is achieved.
In weiterer vorteilhafter Ausgestaltung ist der Gasbag über eine Haltebrücke in einem Gehäuse des Speichers fixiert. Dadurch ist die Position des Gasbags im Speicher definiert. Eine definierte Position führt zu einem verminderten Verschleiß durch Reibung mit dem Gehäuse und einer definierten Strömungssituation von Betriebsmedium mit dem Speicher. In a further advantageous embodiment, the gasbag is fixed via a holding bridge in a housing of the memory. This is the position of the Gasbags defined in the store. A defined position leads to a reduced wear by friction with the housing and a defined flow situation of operating medium with the memory.
Gemäß einem vorteilhaften Unteranspruch weist die Haltebrücke ein Füllkanalsystem für den mindestens einen Gasbag auf. Der Gasbag kann in das Gehäuse des Speichers eingesetzt und anschließend über die Haltebrücke befüllt werden. According to an advantageous embodiment, the retaining bridge has a filling channel system for the at least one gasbag. The gas bag can be inserted into the housing of the storage and then filled via the holding bridge.
