Abstract
Description
Die vorliegende Erfindung betrifft einen Druckspeicher mit einem Gehäuse, welches einen Behälter für Fluid bildet, einem Fluidanschluß für in das Gehäuse ein- oder ausströmendes Fluid, sowie eine Federanordnung, gegen deren Kraft durch den Fluidanschluß einströmendes Bremsfluid arbeitet, wobei zumindest ein Teil der Federanordnung durch wenigstens einen Teil der Wandung des Gehäuses gebildet ist, und wobei ein weiterer Teil der Federanordnung durch ein Federelement gebildet ist.The The present invention relates to a pressure accumulator having a housing, which a container for fluid forms, a fluid connection for in the casing incoming or outgoing Fluid, as well as a spring arrangement, against the force of which fluid flowing through the fluid connection brake fluid works, wherein at least a part of the spring arrangement by at least formed a part of the wall of the housing is, and wherein another part of the spring assembly by a spring element is formed.
Im
Stand der Technik sind Druckspeicher bekannt, die als Gaskolbenspeicher,
als Gasmembranspeicher oder als Gas-Multilayer-Membranspeicher, oder als
Federkolbenspeicher ausgestaltet sind. In den
Die
Der Erfindung liegt die Aufgabe zugrunde, einen Druckspeicher bereitzustellen, bei dem eine variable Einstellung einer dem in den Druckspeicher einströmenden Bremsfluid entgegenwirkenden Kraft möglich ist.Of the Invention has for its object to provide a pressure accumulator, in which a variable adjustment of the brake fluid flowing into the pressure accumulator counteracting force possible is.
Zur Lösung dieser Aufgabe schlägt die Erfindung einen Druckspeicher mit den im Anspruch 1 genannten Merkmalen vor.to solution this task strikes the invention an accumulator with the mentioned in claim 1 Characteristics.
Bei dem erfindungsgemäßen Druckspeicher wird zum einen eine erhebliche Gewichtseinsparung erreicht. Andererseits ermöglicht die Integration zweier Funktionen (Speicherung potentieller Energie und Umschließung des Fluides) in einem Bauteil eine erhebliche Vereinfachung der Gesamtanordnung.at the pressure accumulator according to the invention achieved on the one hand a significant weight saving. on the other hand allows the integration of two functions (storage of potential energy and enclosure the fluid) in a component a considerable simplification of Overall arrangement.
Darüber hinaus werden Dichtungen vermieden, die aufgrund von Reibung verschleißen können. Ferner ermöglicht die erfindungsgemäße Anordnung eine variable Einstellung einer dem in den Druckspeicher einströmenden Bremsfluid entgegenwirkenden Kraft.Furthermore seals are avoided, which can wear due to friction. Further allows the inventive arrangement a variable adjustment of a brake fluid flowing into the pressure accumulator counteracting force.
Vorzugsweise ist der einen Teil der Gehäusewandung bildende Teil der Federanordnung zumindest abschnittsweise durch einen Faltenbalg, vorzugsweise aus Metall, gebildet.Preferably is the one part of the housing wall forming part of the spring arrangement at least partially by a bellows, preferably made of metal.
Um ein möglichst hohes Druckniveau zu erreichen, wirkt parallel zu der durch einen Teil der Gehäusewandung gebildeten Federanordnung ein weiterer Teil der Federanordnung, der vorzugsweise im Inneren des Gehäuses angeordnet ist. Dieser weitere Teil der Federanordnung kann als Schrauben-, Elastomer- oder Spiralfeder oder als Tellerfederpaket ausgebildet sein. Es besteht jedoch auch die Möglichkeit, den weiteren Teil der Federanordnung außerhalb des Gehäuses, beispielsweise das Gehäuse umgebend, anzuordnen.Around one possible reaching high pressure level, works in parallel to the one by Part of the housing wall formed spring assembly another part of the spring assembly, which is preferably arranged in the interior of the housing. This further part of the spring arrangement can be used as screw, elastomer or spiral spring or be designed as a plate spring package. It However, there is also the possibility the other part of the spring assembly outside the housing, for example surrounding the housing, to arrange.
Weitere Vorteile und Eigenschaften werden anhand der nachstehenden Figurenbeschreibung deutlich.Further Advantages and properties will become apparent from the following description of the figures.
Die Probleme hinsichtlich der Temperaturabhängigkeit werden dabei nicht gelöst.The Problems with temperature dependence are not solved.
Außerdem zeigen
die Zeichnungen deutlich den erheblichen Raumbedarf beispielsweise
des Federkolbens gemäß
Erstaunlicherweise
ist es möglich
durch die erfindungsgemäße Ausgestaltung
einen Raumbedarf zu erreichen, der nur unwesentlich über dem
Raumbedarf des Gasdruckspeichers gemäß
Dennoch ist der erfindungsgemäße Druckspeicher nicht (oder) kaum temperaturabhängig und hat aufgrund fehlender bewegter Dichtungen keine Verschleißprobleme.Yet is the pressure accumulator according to the invention not (or) hardly temperature dependent and has no wear problems due to lack of moving seals.
