Abstract
Description
Die vorliegende Erfindung betrifft ein Fluidreservoir, insbesondere einen Bremsflüssigkeitsbehälter gemäß den Merkmalen des Patentanspruches 1.The The present invention relates to a fluid reservoir, in particular a brake fluid reservoir according to the features of claim 1.
Bei Motorrädern ist der Bremsflüssigkeitsbehälter für die Vorderradbremse üblicherweise am Lenker angeordnet und dementsprechend starken Vibrationen ausgesetzt. Im Bremsflüssigkeitsbehälter ist üblicherweise eine elastische Membran vorgesehen, welche die Bremsflüssigkeit gegenüber der Atmosphäre abdichtet und gleichzeitig einen Volumenausgleich im Fluidsystem ermöglicht. Bei einem Bremsflüssigkeitswechsel wird zunächst Bremsflüssigkeit in das System eingefüllt und anschließend wird die Membran bzw. ein Gummibalg in den Bremsflüssigkeitsbehälter eingesetzt. Selbst bei sehr sorgfältiger Arbeitsweise kann zumindest eine gewisse Menge Luft „unter” der Membran bzw. unter dem Gummibalg eingesperrt werden. Bei starken Vibrationen vermischt sich die Bremsflüssigkeit mit der eingeschlossenen Luft. Gelangt das Bremsflüssigkeits-Luft-Gemisch in den Druckraum des Geberzylinders der Bremsanlage, so ist die Bremse nur noch eingeschränkt funktionsfähig oder fällt im Extremfall ganz aus. Die gleiche Problematik tritt auch bei Ausgleichsbehältern anderer Fluidsysteme wie z. B. bei hydraulischen Kupplungssystemen im Automobil- oder Motorradbereich auf.at motorcycles is the brake fluid reservoir for the front brake usually arranged on the handlebars and accordingly exposed to strong vibrations. In the brake fluid reservoir is usually an elastic membrane is provided which the brake fluid across from the atmosphere seals and at the same time a volume compensation in the fluid system allows. At a brake fluid change will be first brake fluid filled into the system and afterwards the membrane or a rubber bellows used in the brake fluid reservoir. Even with very careful Operation can be at least a certain amount of air "under" the membrane or be locked under the rubber bellows. For strong vibrations the brake fluid mixes with the trapped air. Get the brake fluid-air mixture in the pressure chamber of the master cylinder of the brake system, so is the Brake only limited functioning or falls in extreme cases completely off. The same problem also occurs with expansion tanks of others Fluid systems such. B. in hydraulic clutch systems in the automotive or Motorcycle area on.
Eine gewisse Verbesserung ist erreichbar, wenn der Ausgleichsbehälter elastisch gelagert wird oder eine Tilgermasse eingesetzt wird, welche die Schwingungsanregung des Ausgleichsbehälters verringert.A Some improvement is achievable if the expansion tank is elastic is stored or a damping mass is used, which the vibration excitation of the expansion tank reduced.
Aufgabe der Erfindung ist es, ein Fluidreservoir, insbesondere einen Bremsflüssigkeitsbehälter für ein Hydrauliksystem zu schaffen, bei dem die Gefahr, dass beim Befüllen des Hydrauliksystems Luft im Hydrauliksystem eingeschlossen wird, weiter minimiert wird.task The invention is a fluid reservoir, in particular a brake fluid reservoir for a hydraulic system to create at which the risk that when filling the hydraulic system air in the Hydraulic system is included, further minimized.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.These The object is solved by the features of claim 1. advantageous Refinements and developments of the invention are the dependent claims remove.
Ausgangspunkt der Erfindung ist ein Fluidreservoir, insbesondere ein Bremsflüssigkeitsbehälter für ein Hydrauliksystem, der ein topfartiges Gehäuse aufweist, das bis zu einem gewissen Fluidspiegel mit einem Fluid, z. B. Bremsflüssigkeit, befüllt ist. Nach dem Befüllen des Gehäuses des Fluidreservoirs wird in das Gehäuse eine elastische, balgartige „Trenneinrichtung” eingesetzt. Die Trenneinrichtung ermöglicht aufgrund ihrer Elastizität Volumenänderungen, z. B. des Fluids in Folge von Temperaturschwankungen oder des Fluidsystems infolge von Bremsbelagverschleiß. Eine weitere wichtige Funktion der Trenneinrichtung besteht darin, dass sie das in dem Hydrauliksystem eingeschlossene Fluid gegenüber der Atmosphäre möglichst hermetisch abdichtet.starting point the invention is a fluid reservoir, in particular a brake fluid reservoir for a hydraulic system, which has a pot-like housing, this up to a certain fluid level with a fluid, eg. B. brake fluid, filled is. After filling of the housing of the fluid reservoir, an elastic, bellows-type "separating device" is inserted into the housing. The separator allows because of their elasticity Volume changes, z. As the fluid due to temperature fluctuations or the fluid system due to brake pad wear. Another important function of the separator is to maximize the fluid trapped in the hydraulic system to the atmosphere hermetically sealed.
Gemäß der Erfindung weist die Trenneinrichtung einen speziellen Aufbau auf, so dass beim Einsetzten der Trenneinrichtung in das zumindest teilweise mit Fluid befüllte Gehäuse Lufteinschlüsse, welche die Funktion des Hydrauliksystems beeinträchtigen könnten, vermieden werden. Um dies zu erreichen, ist vorgesehen, dass die balgartige Trenneinrichtung einen unteren, vollständig unterhalb des Fluidspiegels befindlichen Gehäuseraum gegenüber einem oberen, höchstens teilweise mit Fluid befüllten Gehäuseraum trennt bzw. abdichtet, wobei die Trenneinrichtung zumindest teilweise in dem im Gehäuse stehenden Fluid untergetaucht ist.According to the invention the separator has a special construction, so that when inserting the separator in the at least partially filled with fluid casing Air pockets, which prevent the function of the hydraulic system could be avoided. Around To achieve this, it is provided that the bellows-like separator a lower, complete Housing space located below the fluid level with respect to a upper, at most partially filled with fluid housing space separates or seals, wherein the separator at least partially in the case standing in the housing Fluid is submerged.
Beim Einsetzten der elastischen balgartigen Trenneinrichtung wird diese somit zumindest teilweise in das Fluid eingetaucht. Luft, die während des Einsetzvorgangs der Trenneinrichtung sich zwischen dem Fluidspiegel und einer „Unterseite” der Trenneinrichtung befindet, wird beim Eintauchen der Trenneinrichtung in das Fluid „nach oben” herausgedrückt.At the Inserting the elastic bellows separator is this thus at least partially immersed in the fluid. Air during the insertion process the separator is between the fluid level and a "bottom" of the separator is pushed out when immersing the separator in the fluid "up".
