Bei
Druckbehältern zur Speicherung flüssiger oder
gasförmiger, unter Druck stehender Medien ist es Stand
der Technik (vgl.
Je nach Einsatzgebiet müssen Hydrospeicher unterschiedlichen Anforderungen gerecht werden. Besonders hohe Anforderungen sind zu erfüllen, wenn derartige Speicher in Hydrauliksystemen hoch entwickelter Kraftfahrzeuge benutzt werden. Dies ist in besonderem Maße der Fall, wenn ein Einsatz bei Wettbewerbsfahrzeugen, wie Formelrennwagen, vorgesehen ist. In diesen Fällen müssen die betreffenden Hydrospeicher nicht nur hohen Belastungen gewachsen sein, und zwar sowohl hinsichtlich mechanischer Belastungen, statischer und dynamischer Natur, einschließlich äußerst hoher Druckbelastungen, sondern es ist darüber hinaus zwingend, dass die Betriebssicherheit, trotz der hohen Belastung, bei geringstem Baugewicht des Speichers erreicht wird.ever According to application, hydraulic accumulators must be different To fit in requirements. Particularly high requirements are to meet if such memory in hydraulic systems high developed motor vehicles. This is special Dimensions of the case when a use in competitive vehicles, like Formula racing car, is provided. In these cases need the relevant hydraulic accumulators not only cope with high loads be, both in terms of mechanical loads, static and dynamic nature, including extreme high pressure loads, but it is beyond compelling that the operational reliability, despite the high load, at the lowest Construction weight of the memory is achieved.
Im Hinblick auf diese Problematik stellt sich die Erfindung die Aufgabe, einen Hydrospeicher der betrachteten Art zur Verfügung zu stellen, der sich, obgleich er den erwähnten, hohen Belastungen gewachsen ist, durch ein minimales Baugewicht auszeichnet.in the With regard to this problem, the invention has the task a hydraulic accumulator of the kind considered available which, although he mentioned the high, Loads has grown, characterized by a minimal structural weight.
Erfindungsgemäß ist diese Aufgabe durch einen Hydrospeicher gelöst, der die Merkmale des Patentanspruches 1 in seiner Gesamtheit aufweist.According to the invention solved this problem by a hydraulic accumulator, which is the Features of claim 1 in its entirety.
Demgemäß besteht eine wesentliche Besonderheit der Erfindung darin, dass die das Speichergehäuse bildenden Gehäuseschalen an ihren einander zugewandten Stirnseiten mittels einer von außen aufgebrachten Umwicklung aus einem Faserverbundwerkstoff oder mittels eines Fasergelegeauftrages druckdicht miteinander verbunden sind. Bei einfachster Bauweise und dadurch minimalem Baugewicht ist dadurch ein Hydrospeicher geschaffen, der bei hohen Belastungen, seien es mechanische, statische oder dynamische Belastungen und/oder Druckbelastungen und/oder thermische Belastungen, ein Höchstmaß an Betriebssicherheit gewährleistet.Accordingly, there is a significant feature of the invention is that the Storage housing forming housing shells to their facing end faces by means of a from the outside applied wrapping of a fiber composite material or by means a fiber fabric order are pressure-tightly interconnected. The simplest construction and thus minimum construction weight is characterized created a hydraulic accumulator, be it at high loads, be it mechanical, static or dynamic loads and / or pressure loads and / or thermal loads, a maximum Operational safety guaranteed.
Bei besonders vorteilhaften Ausführungsbeispielen sind vorzugsweise metallische Gehäuseschalen in Form von Rotationskörpern bezüglich der Längsachse des Gehäuses vorgesehen, deren einander zugekehrte Öffnungsränder einander derart überlappen, dass die an der Überlappung wirksame, durch die aus einem Faserverbundmaterial gebildete Umwick lung erzeugte Abstützkraft und die dieser entgegenwirkende, aufgrund von Innendruck im Speichergehäuse erzeugte Druckkraft eine Klemmkraft an der Überlappung als Haltekraft für die gegenseitige Verankerung der Öffnungsränder der Schalen bilden. Diese Art der gegenseitigen Verankerung gewährleistet bei einfachster Bauweise und geringstem Baugewicht eine Druckfestigkeit des Gehäuses bei sehr hohen Betriebsdrücken, beispielsweise bei Druckspitzen bis 250 bar oder mehr, selbst bei geringen Wandstärken der Schalen, wobei aufgrund der als Gegenlager dienenden äußeren Abstützung durch die Umwicklung der Innendruck im Speichergehäuse die Klemmkräfte gegenüber dem durch die Umwicklung gebildeten Gegenlager verstärkt.at particularly advantageous embodiments are preferred metallic housing shells in the form of rotational bodies with respect to the longitudinal axis of the housing provided, the mutually facing opening edges overlap each other so that those at the overlap effective, formed by the formed of a fiber composite wrapper development generated supporting force and the counteracting, due to internal pressure in the storage enclosure generated compressive force a clamping force on the overlap as a holding force for the mutual anchoring of the opening edges form the shells. This type of mutual anchoring ensures in the simplest construction and lowest construction weight a compressive strength the housing at very high operating pressures, for example at pressure peaks up to 250 bar or more, even with small wall thicknesses the shells, where due to serving as an abutment outer Support by wrapping the internal pressure in the storage enclosure the clamping forces against that by the wrapping strengthened formed counter bearing.
In besonders vorteilhafter Weise kann das bewegbare Trennelement durch eine Membran gebildet sein, deren Umfangsrand an der Überlappung mit einem Verankerungsteil zwischen die Öffnungsränder der Schalen derart eingreift, dass die an der Überlappung wirkende Klemmkraft die Haltekraft für die Verankerung des Verankerungsteils der Membran an den Öffnungsrändern der Schalen bildet. Somit steht die an der Überlappung wirkende Klemmkraft gleichzeitig als Haltekraft für die Verankerung der Membran zur Verfügung, was zu einer besonders signifikanten Vereinfachung der Bauweise führt.In Particularly advantageous manner, the movable partition by a membrane may be formed whose peripheral edge at the overlap with an anchoring part between the opening edges the shells so intervenes that at the overlap acting clamping force the holding force for anchoring the anchoring part of the membrane at the opening edges the shells forms. Thus, that stands at the overlap acting clamping force at the same time as a holding force for the Anchoring of the membrane available, resulting in a particularly significant Simplification of the construction leads.
Wenn hierbei die Anordnung so getroffen ist, dass sich die Öffnungsränder der Schalen im Bereich der halben Gehäuselänge überlappen, dann steht für die Auslenkung der Membran in vorteilhafter Weise beidseits jeweils etwa der gleiche Freiraum im Gehäuse zur Verfügung.If In this case, the arrangement is made such that the opening edges the shells overlap in the area of half the housing length, then stands for the deflection of the membrane in an advantageous Way both sides each about the same free space in the housing to disposal.
Das Verankerungsteil am Umfangsrand der Membran kann vorzugsweise durch einen verdickten Randwulst der Membran gebildet sein, der insofern eine Art Dichtring an der Verankerungsstelle bildet.The Anchoring part at the peripheral edge of the membrane may preferably by be formed a thickened edge bead of the membrane, the extent one Art seal forms at the anchorage.
Die Anordnung kann hierbei vorzugsweise so getroffen sein, dass der Öffnungsrand derjenigen Schale, die an der Überlappungsstelle radial innenliegend ist, ein annähernd C-förmiges Hohlprofil bildet, das einen radial nach innen und einen im Abstand davon radial nach außen verlaufenden Schenkel bildet, zwischen denen der Randwulst der Membran aufnehmbar ist, der an seiner Außenseite an der Innenseite des überlappenden Öffnungsrandes der anderen Schale anliegt.In this case, the arrangement may preferably be made such that the opening edge of that shell, which is radially inward at the overlapping point, forms an approximately C-shaped hollow profile Det, which forms a radially inwardly and at a distance thereof radially outwardly extending leg, between which the edge bead of the membrane is receivable, which rests on its outer side on the inside of the overlapping opening edge of the other shell.
Bei besonders bevorzugten Ausführungsbeispielen ist die Anordnung so getroffen, dass der Öffnungsrand der an der Überlappungsstelle radial außenliegenden Schale zur Bildung eines absatzlosen Überganges der Außenfläche beider Schalen an einer Ringfläche anliegt, die durch eine Stufe gebildet ist, die am Öffnungsrand der anderen Schale am Übergang zum Hohlprofil vorgesehen ist. Dadurch ergibt sich nicht nur eine durch die Außenseite der Umwicklung gebildete, absatzlose, glatte Außenkontur des Speichergehäuses, sondern die Schalen sind zusätzlich gegen eine gegeneinander gerichtete relative Axialbewegung gesichert.at particularly preferred embodiments is the arrangement so that the opening edge of the at the overlap radially outer shell to form a heelless transition the outer surface of both shells on an annular surface is present, which is formed by a step, the opening edge the other shell provided at the transition to the hollow profile is. This does not just give you one through the outside the wrap formed, choppy, smooth outer contour of the storage enclosure, but the shells are additional secured against an oppositely directed relative axial movement.
Bei besonders bevorzugten Ausführungsbeispielen sind die Schalen aus einer Aluminiumlegierung gebildet, wodurch sich trotz hoher Belastbarkeit ein besonders geringes Baugewicht ergibt.at Particularly preferred embodiments are the shells made of an aluminum alloy, which despite high Resilience results in a particularly low structural weight.
Vorzugsweise sind die Anschlüsse der Schalen durch zur Längsachse koaxiale, angeformte Anschlusskörper gebildet, an die sich die Wand der betreffenden Schale mit gegenüber der Dicke der Anschlusskörper verringerter Wandstärke anschließt. Besonders gute Festigkeitseigenschaften ergeben sich, wenn die Umwicklung im Bereich des Überganges zwischen Anschlusskörper und verringerter Wandstärke der Schale eine Verdickung bildet. Dadurch wirkt die Umwicklung auch als Verstärkung des betreffenden Anschlusskörpers gegen im Betrieb an ihm wirkende Lastkräfte oder Schwingungen.Preferably are the connections of the shells through to the longitudinal axis coaxial, molded connector body formed to the the wall of the shell concerned with respect to the thickness the connection body of reduced wall thickness connects. Especially good strength properties arise when wrapping in the region of the transition between connection body and reduced wall thickness of the shell thickening forms. As a result, the wrapping also acts as a reinforcement of the relevant connection body against in operation on him acting load forces or vibrations.
Die Umwicklung kann aus einem Material gebildet sein, das Kohlenstoff-, Kevlar®-, Glas-, Bor-, Al2O3-Fasern oder ein Gemisch hieraus enthält.The wrapping may be formed of a material containing carbon, Kevlar ® -, glass, boron, Al 2 O 3 fibers or a mixture containing thereof.
