Description
Die Erfindung betrifft ein Hydraulikaggregat umfassend einen Aufnahmekörper mit elektrohydraulischen Ventilen, mit wenigstens einer hydraulischen Pumpe, und mit Kanälen zur Verbindung der Pumpe mit wenigstens einem hydraulischen Verbraucher, wobei der Pumpe ein, im Aufnahmekörper integrierter, Pulsationsdämpfer umfassend ein Medientrennelement aus elastischem Werkstoff zugeordnet ist, welches eine Fluidkammer von einer pneumatischen Kammer trennt.The The invention relates to a hydraulic unit comprising a receiving body with Electrohydraulic valves, with at least one hydraulic Pump, and with channels for connecting the pump to at least one hydraulic consumer, the pump comprising a, integrated in the receiving body, pulsation damper a media separating element of elastic material is assigned, which separates a fluid chamber from a pneumatic chamber.
Der WO 97/14591 ist ein gattungsgemäßes Hydraulikaggregat mit einer Einrichtung zur Aktivbremsung zu entnehmen, wobei zwischen einem Hauptzylinder und einer Saugseite einer Pumpe ein Pulsationsdämpfer angeordnet ist, welcher eine verformbare Membran aufweist, die einen druckmittelgefüllten Bereich von einem gasgefüllten Bereich trennt (Membrandämpfer), wobei der gasgefüllte Bereich eine geschlossene Kammer bildet, und die Kammer einen ersten Abschnitt aufweist, der für die Membran zugänglich ist, und einen zweiten Abschnitt der für die Membran unzugänglich ist, wobei ein Gasaustausch zwischen den beiden Abschnitten möglich ist.Of the WO 97/14591 is a generic hydraulic unit to be taken with a device for active braking, with between a main cylinder and a suction side of a pump arranged a pulsation damper which has a deformable membrane which is a pressure medium filled area from a gas-filled Area separates (membrane damper), the gas-filled Area forms a closed chamber, and the chamber a first Section has for the membrane accessible is, and a second section is inaccessible to the membrane, whereby a gas exchange between the two sections is possible.

Es ist eine Aufgabe der vorliegenden Erfindung, die Effektivität der Pulsationsminderung in einem elektrohydraulisch geregelten Fahrzeugbremssystem bei geringem Aufwand über deren gesamte Betriebszeit zu verbessern, sowie das Einbauvolumen der Dämpfungsmittel zu verringern.It An object of the present invention is the effectiveness of pulsation reduction in an electrohydraulically controlled vehicle braking system at low Effort over improve their overall uptime, as well as the installation volume the damping means to reduce.
Die Aufgabe wird bei einem Membrandämpfer der angegebenen Art mit der Merkmalskombination des Patentanspruchs 1 gelöst, indem der Pulsationsdämpfer zwischen einer Hochdruckseite der Pumpe und dem hydraulischen Verbraucher angeordnet ist, dass der Pulsationsdämpfer eine einzige pneumatische Kammer aufweist, welche von dem Medientrennelement und einem Bohrungsverschluss begrenzt ist, und dass die Fluidkammer von einer Aufnahmebohrung im Aufnahmekörper und dem Medientrennelement begrenzt ist.The Task becomes with a membrane damper the specified type with the feature combination of the claim 1 solved, by the pulsation damper between a high-pressure side of the pump and the hydraulic consumer is arranged that the pulsation damper a single pneumatic Chamber which delimits the media separator and a bore closure is, and that the fluid chamber of a receiving bore in the receiving body and is limited to the media separating element.
Erfindungsgemäß ist der Pulsationsdämpfer zwischen Druckseite der Pumpe und dem hydraulischen Verbraucher angeordnet, und verfügt über eine einzige geschlossene pneumatische Kammer. Vorteilhafterweise ist die Bauteilanzahl bei dennoch einfach justierbarer Dämpfungswirkung erfreulich gering. Ein besonderer Vorteil der Erfindung liegt darin begründet, dass ein erfindungsgemäßes Fahrzeugbremssystem selbst nach einem Membranriss funktionsfähig bleibt, und lediglich eine Komforteinschränkung infolge Verlust der Dämpfungsfunktion eintritt. Denn eine Verseuchung des Bremssystems durch Luft oder Feuchtigkeit ist nicht zu befürchten. Eine Justierung der Dämpfungswirkung ist einfach und in systematischer Art und Weise durch Änderung von Geometrie, Vorspannung oder Shore-Härte des Medientrennelementes wie auch durch Änderung der pneumatischen Druckverhältnisse in der pneumatischen Kammer machbar. Der Membrandämpfer ist dadurch vergleichsweise einfach an eine Vielzahl von Anwendungsfälle adaptierbar.According to the invention Pulsation damper between Pressure side of the pump and the hydraulic consumer arranged and has one only closed pneumatic chamber. Advantageously the number of components with still easily adjustable damping effect pleasingly low. A particular advantage of the invention lies in the fact that an inventive vehicle brake system even after a membrane rupture remains functional, and only one comfort restriction due to loss of damping function entry. Because a contamination of the brake system by air or Moisture is not to be feared. An adjustment of the damping effect is simple and systematic by change geometry, preload, or shore hardness of the media separator as well as by change the pneumatic pressure conditions feasible in the pneumatic chamber. The diaphragm damper is thereby comparatively easy to adapt to a variety of applications.
Eine Aus- und Abrundung von Bohrungsstufen der Aufnahmebohrung ermöglicht eine Vakuumbefüllung des Pulsationsdämpfers.A rounding off of Bohrstu fen of the receiving bore allows a vacuum filling of the pulsation damper.
Indem der Bohrungsverschluss Mittel zum Zentrieren des Medientrennelementes aufweist, wird die Montage des Dämpfers erleichtert, weil ein Verrutschen des elastischen Werkstoffes verhindert wird.By doing the bore closure means for centering the media separator has, is the assembly of the damper relieved because slippage of the elastic material is prevented.
Wenn der Bohrungsverschluss als Deckel mit im wesentlichen scheibenförmiger Basis und einem Zentralvorsprung ausgebildet ist, ermöglicht dies eine kostengünstige Herstellung unter Verwendung von spanenden oder spanlosen Herstellungsverfahren wie insbesondere Fließpressverfahren.If the bore closure as a lid with a substantially disc-shaped base and a central projection is formed, this allows a cost-effective production using machining or non-cutting manufacturing processes such as in particular extrusion molding.
Dem Zentralvorsprung kommt jedoch nicht nur die Funktion einer Zentrierung des Medientrennelementes während dessen Montage zu. Denn ein Boden des Zentralvorsprungs ist zur Abstützung des Medientrennelementes konkav ausgebildet.the However, the central advantage is not just the function of centering of the media separator during its mounting too. Because a floor of the central projection is to support the media separating element is concave.
Dadurch wird der nutzbare Kompressionsraum in dem pneumatischen Raum in einer Weise erhöht, welche auch der Lebensdauer der Membran zu gute kommt. Denn die konkave Bodengestaltung ermöglicht ferner eine weitgehend mittig angreifende und zukzessiv zunehmende Zentrierwirkung, selbst wenn die Membran unter der Wirkung von hohen, hydraulisch pulsierenden Kräften stoßartig pulsierend an den Boden angelegt wird. Diese Maßnahme reduziert die Gefahr eines Membranriss. Eine zusätzliche, gleichwirkende Maßnahme sind großzügige, symmetrisch umlaufende Ausrundungen im Übergang zwischen Basis, Wandung und Boden.Thereby is the usable compression space in the pneumatic space in a way increased which also benefits the life of the membrane. Because the concave floor design allows Furthermore, a largely center attacking and increasing gradually Centering effect, even if the membrane under the action of high, hydraulically pulsating forces jerky is applied pulsating to the ground. This measure reduces the risk a membrane tear. An additional, equivalent effect measure are generous, symmetrical circumferential rounding in the transition between base, wall and floor.
Prinzipiell ist der Bohrungsverschluss mit dem Aufnahmekörper formschlüssig verbunden, insbesondere verschraubt, verstemmt oder verclincht. Wenn das Medientrennelement fest an einer Bohrungsstufe der Aufnahmebohrung anliegt, kann durch eine definierte Eintauchtiefe von dem Bohrungsverschluss in Relation zu dem Medientrennelement eine definierte Druckspannung innerhalb des Medientrennelementes erzielt werden, um auf diesem Weg die Dämpfungswirkung zu justieren. Der Bohrungsverschluss wird zwecks Montage auf das Medientrennelement gepresst und parallel dazu werden die benötigten Kräfte ermittelt, und schließlich wird der Bohrungsverschluss festgelegt, wenn die gewünschten Druckspannungen im Medientrennelement erzielt sind.in principle the bore closure is positively connected to the receiving body, in particular screwed, caulked or clinched. If the media separator firmly abuts a bore stage of the receiving bore can through a defined immersion depth of the bore closure in relation to the media separating a defined compressive stress within be achieved of the media separating element, in this way the damping effect to adjust. The bore plug is mounted on the media separator for mounting pressed and in parallel the required forces are determined, and finally the hole lock set when the desired compressive stresses in the Media separator are achieved.
Nach einer vorteilhaften Ausführungsform der Erfindung ist das Medientrennelement kalottenförmig ausgebildet, und ragt mit einer konvexen Ausstülpung in die Aufnahmebohrung, um mit der gegenüberliegenden konkaven Ausstülpung den Zentralvorsprung zur Bildung der pneumatischen Kammer zu übergreifen. Die Kalottenform des Medientrennelementes ermöglicht eine optimiert-zentrische Einleitung der hydraulischen Druckkräfte, indem sich gegenläufig gerichtete Kraftvektoranteile selbsttätig aufheben, während sich axial gerichtete Kraftvektoranteile addieren.To an advantageous embodiment of the Invention, the media separating element is dome-shaped, and protrudes with a convex protuberance in the receiving bore, with the opposite concave protuberance the central projection to spread to the formation of the pneumatic chamber. The dome shape allows the media separating element an optimized-centric initiation of hydraulic pressure forces by in opposite directions self-picking up directed force vector portions while Add axially directed force vector components.
Zur bauraumneutralen Erhöhung des nutzbaren Kompressionsraumes der pneumatischen Kammer weist diese zwischen Medientrennelement und Bohrungsverschluss einen linsenförmigen Querschnitt auf, wobei vorzugsweise zuzüglich zu dem linsenförmigen Querschnitt noch ein parallel zu der Wandung des Zentralvorsprunges verlaufender, zylindrischer Bereich vorgesehen ist.to Space-neutral increase the usable compression space of the pneumatic chamber has this between media separating element and bore closure a lenticular cross-section on, preferably plus to the lenticular Cross-section still one parallel to the wall of the central projection extending, cylindrical area is provided.
Zwecks adaptiver Anpassung an andere Umgebungsbedingungen kann der Pulsationsdämpfer in Reihe oder parallel zu einer beblendeten Pulsationsdämpfungskammer vorgesehen sein.For the purpose of adaptive adaptation to other environmental conditions, the pulsation damper in Row or parallel to a blinded Pulsationsdämpfungskammer be provided.
