Eine derartige Kolbenpumpe ist beispielsweise aus
Wie z.B. in
Es ist eine Aufgabe der vorliegenden Erfindung ein Fahrzeugbremssystem mit einer Kolbenpumpe zu schaffen, deren Verhalten im Hinblick auf eine gleichmäßige Ausförderung von Fluid in verschiedensten Leistungsbereichen jenem Verhalten bekannter Kolbenpumpen überlegen ist.It is an object of the present invention to create a vehicle brake system with a piston pump, the behavior of which is superior to that of known piston pumps with regard to a uniform delivery of fluid in the most varied of power ranges.
Offenbarung der ErfindungDisclosure of the invention
Erfindungsgemäß ist eine Kolbenpumpe für eine hydraulische Fahrzeugbremsanlage mit einer Abströmöffnung für abströmendes Fluid geschaffen, die mit einem Schließkörper wahlweise verschließbar ist, und einer in Strömungsrichtung nachfolgenden Abströmung für das abströmende Fluid, bei der der Schließkörper mit einem Kalottenabschnitt und einem Schaftabschnitt gestaltet ist, der in einer Führungsbohrung geführt verschiebbar ist, und bei der die Abströmung mit einem Dämpfungselement für das abströmende Fluid gestaltet ist.According to the invention, a piston pump for a hydraulic vehicle brake system is created with an outflow opening for outflowing fluid, which can be optionally closed with a closing body, and a downstream outflow for the outflowing fluid in the direction of flow, in which the closing body is designed with a spherical portion and a shaft portion, which in a guide bore is displaceable in a guided manner, and in which the outflow is designed with a damping element for the outflowing fluid.
Ferner ist erfindungsgemäß ein Fahrzeugbremssystem mit einer derartigen Kolbenpumpe geschaffen.Furthermore, according to the invention, a vehicle brake system with such a piston pump is created.
Mit anderen Worten liegt der Kern der Erfindung darin, dass ein kalottenförmiger Schließkörper bzw. eine Kalotte eines Auslassventils einer Kolbenpumpe mit einem Dämpfungselement kombiniert ist. Das Dämpfungselement ist mittels einer Verbindungsleitung mit der Kalotte strömungsleitend verbunden. Der Auslass der Kolbenpumpe, also der Ausgang der Abströmung erfolgt nach dem Dämpfungselement.In other words, the essence of the invention is that a dome-shaped closing body or a dome of an outlet valve of a piston pump is combined with a damping element. The damping element is connected to the dome in a flow-conducting manner by means of a connecting line. The outlet of the piston pump, i.e. the outlet of the outflow, takes place after the damping element.
Mit der erfindungsgemäßen Ausgestaltung ist eine Fahrzeugbremsanlage geschaffen, deren Kolbenpumpe einen besonders schwingungsarmen und geräuschfreien Ausstoß von Bremsfluid liefert.With the embodiment according to the invention, a vehicle brake system is created whose piston pump delivers a particularly low-vibration and noise-free ejection of brake fluid.
Gemäß der Erfindung ist ferner die Abströmung mit einem Leitungsabschnitt ausgebildet, der eine Strömungsverbindung zwischen dem Kalottenabschnitt und dem Dämpfungselement unter Umgehung der Führungsbohrung schafft.According to the invention, the outflow is also formed with a line section which creates a flow connection between the spherical section and the damping element while bypassing the guide bore.
Mit der derartigen Weiterbildung sind die Kalotte und das Dämpfungselement unmittelbar in Reihe geschaltet, ohne dass andere strömungstechnisch gegebenenfalls störende Elemente dazwischen liegen. Mittels einer angemessenen Auslegung der Elemente Kalotte und Dämpfungselement kann das strömungstechnische Verhalten der derartigen Kolbenpumpe dadurch vergleichsweise leicht und genau wunschgemäß vorherbestimmt werden.With such a development, the spherical cap and the damping element are connected directly in series without any other elements that may interfere with the flow between them. By means of an appropriate design of the elements of the spherical cap and the damping element, the fluidic behavior of the piston pump of this type can thereby be predetermined comparatively easily and precisely as desired.
Gemäß einer vorteilhaften Weiterbildung der erfindungsgemäßen Kolbenpumpe ist der Leitungsabschnitt im Wesentlichen parallel zur Führungsbohrung ausgebildet.According to an advantageous development of the piston pump according to the invention, the line section is formed essentially parallel to the guide bore.
Die parallele Anordnung des Leitungsabschnittes relativ zur Führungsbohrung lässt sich fertigungstechnisch besonders kostengünstig herstellen und bietet darüber hinaus den Vorteil einer besonders kompakten Bauform.The parallel arrangement of the line section relative to the guide bore can be produced in a particularly cost-effective manner in terms of production technology and also offers the advantage of a particularly compact design.
Gemäß einer weiteren vorteilhaften Weiterbildung der erfindungsgemäßen Kolbenpumpe ist am Ende der Abströmung eine Drossel für das abströmende Fluid angeordnet.According to a further advantageous development of the piston pump according to the invention, a throttle for the outflowing fluid is arranged at the end of the outflow.
Der Auslass der erfindungsgemäßen Kolbenpumpe erfolgt nach dem Dämpfungselement. Vor dem Auslass ist gemäß der letztgenannten Weiterbildung eine Drossel verbaut. Diese verbessert und unterstützt durch ihre aufstauende Wirkung die Funktion des Dämpfungselements.The piston pump according to the invention is discharged after the damping element. According to the last-mentioned development, a throttle is installed in front of the outlet. This improves and supports the function of the damping element through its damming effect.
Gemäß einer weiteren vorteilhaften Weiterbildung der erfindungsgemäßen Kolbenpumpe ist eine weitere Drossel zwischen dem Schließkörper und dem Dämpfungselement in Reihe geschaltet.According to a further advantageous development of the piston pump according to the invention, a further throttle is connected in series between the closing body and the damping element.
Die derartige Weiterbildung verbessert das Verhalten der Kolbenpumpe im Hinblick auf das Schwingungsverhalten des Schließkörpers und der beim Öffnen sowie Schließen entstehenden Geräusche weiter.Such a development improves the behavior of the piston pump with regard to the vibration behavior of the closing body and the noises generated when opening and closing.
Gemäß einer weiteren vorteilhaften Weiterbildung der erfindungsgemäßen Kolbenpumpe ist das Dämpfungselement unmittelbar an der Abströmleitung der Abströmung angeordnet.According to a further advantageous development of the piston pump according to the invention, the damping element is arranged directly on the outflow line of the outflow.
Die derartige Anordnung des Dämpfungselements unmittelbar im Abströmweg hinter dem kalottenförmigen Schließkörper wird vorliegend auch als „Reihenschaltung“ bezeichnet. Das Dämpfungselement wirkt dabei nämlich grundsätzlich auf das gesamte abströmende Fluid, während sich dieses auf dem Abströmweg am Dämpfungselement vorbeibewegt.Such an arrangement of the damping element directly in the outflow path behind the dome-shaped closing body is also referred to as a “series connection” in the present case. The damping element basically acts on the entire outflowing fluid while this moves past the damping element on the outflow path.
Gemäß einer weiteren vorteilhaften Weiterbildung der erfindungsgemäßen Kolbenpumpe ist das Dämpfungselement an einer von der Abströmleitung der Abströmung abzweigenden Leitung angeordnet.According to a further advantageous development of the piston pump according to the invention, the damping element is arranged on a line branching off from the outflow line of the outflow.
Mit dieser Anordnung eines Dämpfungselements an einer Abzweigung vom Hauptströmungsweg des Fluids aus dem Pumpenelement heraus ist eine „Parallelschaltung“ geschaffen, bei der das Fluid einerseits durch die Abströmung abfließen kann und zugleich von der Abzweigung und dem dort wirkenden Dämpfungselement aus in seinem grundsätzlich pulsierenden Strömungsverhalten gedämpft wird.With this arrangement of a damping element at a branch from the main flow path of the fluid out of the pump element, a "parallel connection" is created, in which the fluid can flow away through the outflow and at the same time dampened in its fundamentally pulsating flow behavior by the branch and the damping element acting there will.
Gemäß einer weiteren vorteilhaften Weiterbildung der erfindungsgemäßen Kolbenpumpe gehen von der Abströmöffnung sowohl die Abströmleitung als auch die abzweigende Leitung ab.According to a further advantageous development of the piston pump according to the invention, both the discharge line and the branching line branch off from the discharge opening.
Die Abströmöffnung bildet damit ein zentrales Element, von dem aus sich die Leitungswege erstrecken. Dies führt zu einer besonders ausgewogenen Strömungssituation an dem an der Abströmöffnung sich bewegenden Schließkörper.The outflow opening thus forms a central element from which the conduction paths extend. This leads to a particularly balanced flow situation on the closing body moving at the outflow opening.
Gemäß einer weiteren vorteilhaften Weiterbildung der erfindungsgemäßen Kolbenpumpe ist die Abströmöffnung kreisrund gestaltet und die abzweigende Leitung geht am Umfang der Abströmöffnung in einem Winkel von 90° versetzt zur Abströmleitung von der Abströmöffnung ab.According to a further advantageous development of the piston pump according to the invention, the outflow opening is circular and the branching line branches off from the outflow opening at the circumference of the outflow opening at an angle of 90 ° to the outflow line.
Die derart versetzte Anordnung der abzweigenden Leitung führt zu einer insgesamt unsymmetrischen Strömungssituation, wodurch insbesondere das Entstehen von Resonanzschwingungen am Schließkörper verringert werden kann.The offset arrangement of the branching line leads to an overall asymmetrical flow situation, whereby in particular the occurrence of resonance vibrations on the closing body can be reduced.
