Description
Die Erfindung betrifft ein Hydraulikaggregat für eine hy draulische Steuer- oder Regelvorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a hydraulic unit for a hy drastic control or regulating device according to the preamble of claim 1.
Aus der DE-OS 38 31 426 A1 ist bereits ein Hydraulikaggregat mit den im Hauptanspruchsoberbegriff genannten Merkmalen be kannt. Bei diesem Hydraulikaggregat bedarf es bei der abbil dungsgemäßen Anordnung in einem Kraftfahrzeug besonderer Maß nahmen, um die Spezifikationen zur Funktionstüchtigkeit der Anlage, beispielsweise dem Salzsprühtest und damit den spä teren alltäglichen Anforderungen im Betrieb an Salz- und Spritzwasserunempfindlichkeit gerecht zu werden. Zur Erfül lung der Spezifikationen werden daher häufig besondere Korrosionsschutzmaßnahmen getroffen, die das Aggregat in der Regel verteuern und u. U. nur bedingt wirksam sind. Um diesen Gegebenheiten entgegenzuwirken, wären zwar besondere Einbau orte und Einbaulagen des Hydraulikaggregates wünschenswert, diese können jedoch infolge der komplexen Aggregateanordnung im Gesamtverbund, beispielsweise innerhalb des Kraftfahr zeuges, und zudem durch die eskalierende Integrationsdichte häufig nicht bewerkstelligt werden. So hat sich beispiels weise erwiesen, daß insbesondere bei waagerechter Anordnung des Druckspeichers die Korrosionsgefährdung im Gleitbereich des Druckspeicherkolbens besonders groß ist, da gerade bei waagerechter Anordnung des Hydraulikaggregates günstige Vor aussetzungen für das Eindringen von Salz- bzw. Spritzwasser in die Druckspeicheröffnung geschaffen werden, wobei es überdies zu Spritzwasseransammlung kommen kann, das nur schwerlich wieder abfließt. Das bestehende Problem durch An bringen eines wie in der Druckschrift gezeigten Druckspei cherverschlußdeckels oder evtl. einer Deckelverschraubung zu lösen, trägt nicht nur zur Gewichts- und Kostenerhöhung bei, sondern verhindert außerdem das Be- und Entlüften der Druck speicheröffnung zum Zwecke des Druckausgleichs in der Druck speicherkammer, was sich im Betrieb, insbesondere während der Druckspeicherladephase negativ auswirken kann.DE-OS 38 31 426 A1 is already a hydraulic unit with the features mentioned in the main preamble of the claim knows. This hydraulic unit requires the abbil arrangement according to the invention in a motor vehicle of special dimensions took to the functionality specifications of the Plant, for example the salt spray test and thus the late other everyday requirements in the operation of salt and Splash water insensitivity. To fulfill The specifications are therefore often special Corrosion protection measures taken that the unit in the Rule expensive and u. U. are only partially effective. To this To counteract circumstances would be special installation locations and installation positions of the hydraulic unit desirable, however, these can be due to the complex assembly arrangement in the overall network, for example within motor vehicles stuff, and also due to the escalating integration density are often not accomplished. For example proven, in particular, that it is horizontal of the pressure accumulator the risk of corrosion in the sliding area of the pressure accumulator piston is particularly large, since at horizontal arrangement of the hydraulic unit favorable before Exposure to the ingress of salt or splash water be created in the accumulator opening, it moreover, splash water can accumulate, that only hardly flows out again. The existing problem through An bring a printed copy as shown in the document locking lid or possibly a screwed lid not only helps to increase weight and costs, but also prevents the pressure from being vented memory opening for the purpose of pressure equalization in the pressure storage chamber, which is in operation, especially during the accumulator loading phase can have a negative impact.
Daher ist es die Aufgabe der Erfindung, ein Hydraulik aggregat zu schaffen, dessen Druckspeicher korrosionsge schützt, kosten- und gewichtsreduziert und unabhängig von den Anordnungserfordernissen des Gesamtaggregates in Ventil aufnahmekörper integriert werden kann, ohne daß die dem Druckspeicherraum abgewandte Kammer flüssigkeits- und differenzdruckbeaufschlagt wird.Therefore, the object of the invention is a hydraulic system to create aggregate, the pressure accumulator corrosion protects, reduces costs and weight and is independent of the arrangement requirements of the overall unit in valve recording body can be integrated without the Pressure storage chamber facing away from liquid and differential pressure is applied.
Diese Aufgabe wird erfindungsgemäß durch die den Patentan spruch 1 kennzeichnenden Merkmale gelöst. Die Erfindung ba siert somit auf dem Gedanken, den Ventilaufnahmekörper mit einem gasdurchlässigen, jedoch flüssigkeits- und festkörper partikelundurchlässigen Wandabschnitt zu versehen, der von einer druckausgeglichenen Kammer des Druckspeichers begrenzt wird.This object is achieved by the patent pronounced 1 characteristic features solved. The invention ba is based on the idea of including the valve body a gas-permeable, but liquid and solid body particle-impermeable wall section to be provided by limited a pressure-balanced chamber of the pressure accumulator becomes.
Eine weitere Präzisierung des Erfindungsgedankens geht aus den Merkmalen der Ansprüche 2 und 3 hervor, wonach der gas durchlässige Wandabschnitt eine in einer Seitenfläche des Ventilaufnahmekörpers befindlichen Öffnung flüssigkeitsun durchlässig verschließt und wobei die Öffnung den im Ventil aufnahmekörper eingesetzten Druckspeicher in der waagerech ten Montageebene des Hydraulikaggregates aufnimmt.A further clarification of the idea of the invention goes out the features of claims 2 and 3, according to which the gas permeable wall section one in a side surface of the Valve receiving body located liquid permeable closes and the opening in the valve receiving body used pressure accumulator in the horizontal mounting level of the hydraulic unit.
Eine besonders zuverlässige, leichtbauende und kosten günstige Lösung des bestehenden Problems wird durch die Merkmale der Ansprüche 4 und 5 beschrieben, wonach der Wand abschnitt aus einer atmungsaktiven Membran gebildet ist, oder aus einem hydrophobierten Material mit geringer Formän derung, vorzugsweise Kunstfasermaterial mit hoher Gewebe dichte, besteht.A particularly reliable, lightweight and cost cheap solution to the existing problem is through the Features of claims 4 and 5 described, according to which the wall section is formed from a breathable membrane, or from a hydrophobized material with a low shape change, preferably synthetic fiber material with high fabric density, consists.
Den gasdurchlässigen Wandabschnitt, gemäß Anspruch 6, aus einem semipermeablen Gewebe herzustellen, stellt eine wei tere zweckmäßige Ausgestaltung des Erfindungsgedankens dar, der sowohl durch die Verwendung einer Membran oder durch das hydrophobierte Material hoher Steifigkeit zum Tragen kommen.The gas-permeable wall section, according to claim 6 to produce a semi-permeable fabric, a white tere appropriate design of the inventive concept, which both through the use of a membrane or through the hydrophobic material with high rigidity.
Die Merkmale der Ansprüche 7 bis 9 beschreiben eine zweck mäßige Konstruktionsform und mehrere Befestigungsarten für die gasdurchlässige Wand, wonach der Wandabschnitt entlang seinem Umfang ein mit einem Stützkörper eingefaßtes Gewebe material aufweist, das mittels Reibschluß oder Formschluß flüssigkeitsdicht in der Öffnung des Druckspeichers gehalten wird.The features of claims 7 to 9 describe a purpose moderate design and several types of fastening for the gas permeable wall, after which the wall section along its circumference a tissue edged with a support body has material that by means of frictional engagement or positive engagement held liquid-tight in the opening of the pressure accumulator becomes.
Die Merkmale und Vorteile der Erfindung werden nachfolgend anhand einer Zeichnung näher dargestellt und erläutert.The features and advantages of the invention are as follows illustrated and explained with reference to a drawing.
Die Fig. 1 zeigt ein Hydraulikaggregat im Teilschnitt skizziert. Der Teilschnitt erstreckt sich im Bereich des den Druckspeicher 4 aufweisenden Ventilaufnahmekörpers 1 und ist zur Verdeutlichung der Einzelteile im Maßstab vergrößert ge zeichnet. Der Druckspeicher 4 besteht im wesentlichen aus einem Druckspeicherkolben 7, der axial beweglich sowie an seiner Mantelfläche gegenüber dem Speicherraum 8 flüssig keitsdicht geführt, in einer als Sackbohrung gestaltete Öff nung 5 gleitet. Eine auf der dem Speicherraum 8 abgewandten Kolbenseite anliegende Druckfeder 9 stützt sich an einem scheibenförmigen Anschlag 10 ab. Der Druckspeicherkolben 7 weist zu beiden Kolbenstirnflächen einen Führungszapfen 11 auf, der in der entspannten Position der Druckfeder 9 an der Stirnwand des Speicherraumes 8 anliegt. Die Stirnwand des Speicherraumes 8 weist einen Druckmittelkanal 12 auf, der an einer nicht näher gezeigten magnetventilgesteuerten Druck mittelrückführ- und Pumpenzuführleitung angeschlossen ist. In der Zeichnung befindet sich in einem definierten Abstand zum Anschlagzapfen 11 der gasdurchlässige, jedoch flüssig keits- und festkörperpartikelsperrende Wandabschnitt 2, der beispielsweise aus einem hydrophobierten Material herge stellt ist und dessen engmaschiges Kunstfasergewebe von einem ringförmigen Stützkörper 6 formstabil umschlossen ist. Der Stützkörper 6 liegt flüssigkeitsdicht an dem bundförmi gen Absatz der Öffnung 5 an, so daß die bis zum Druck speicherkolben 7 reichende Kammer 3 lediglich unter atmosphärem Druck steht. Damit ist sichergestellt, daß beim Entlade- und Ladevorgang des Druckspeichers 4 ein ungehin dertes Be- und Entlüften der Kammer 3 über den gasdurchläs sigen Wandabschnitt 2 stattfinden kann, ohne daß Feuchtig keit in den Bereich der Kammer 3 gelangen kann. Durch den seitlichen Verschluß des Ventilaufnahmekörpers 1 mittels des gasdurchlässigen Wandabschnitts 2, ist in der Kammer 3 auf kostengünstige Weise jederzeit ein Druckausgleich geschaffen. Fig. 1 shows a hydraulic power unit in partial section outlined. The partial section extends in the region of the pressure accumulator 4 having valve receiving body 1 and is enlarged to clarify the individual parts ge drawn. The accumulator 4 essentially consists of a pressure accumulator piston 7 is axially movably guided, as well as on its outer surface with respect to the memory space 8 liquid-tight manner, in a voltage designed as a blind bore Publ 5 slides. A compression spring 9 resting on the piston side facing away from the storage space 8 is supported on a disk-shaped stop 10 . The pressure accumulator piston 7 has a guide pin 11 on both piston end faces, which in the relaxed position of the compression spring 9 bears against the end wall of the storage space 8 . The end wall of the storage space 8 has a pressure medium channel 12 , which is connected to a solenoid-controlled pressure medium return and pump supply line, not shown in more detail. In the drawing, at a defined distance from the stop pin 11 of the gas-permeable, but liquid keits- and solid-particle-blocking wall section 2 , which is for example made of a hydrophobic material Herge and whose close-knit synthetic fiber fabric is enclosed in a dimensionally stable manner by an annular support body 6 . The support body 6 is liquid-tight on the bundformi gene paragraph of the opening 5 , so that the up to the pressure storage piston 7 reaching chamber 3 is only under atmospheric pressure. This ensures that during the unloading and loading process of the pressure accumulator 4, an unhindered ventilation of the chamber 3 can take place via the gas-permeable wall section 2 without moisture being able to get into the area of the chamber 3 . Due to the lateral closure of the valve receiving body 1 by means of the gas-permeable wall section 2 , pressure equalization is created in the chamber 3 at any time in a cost-effective manner.
