Abstract
Description
Die Erfindung betrifft eine hydraulische Arbeitsmaschine nach dem Oberbegriff des Patentanspruchs 1. The invention relates to a hydraulic working machine according to the preamble of
Aus
In der Summe ergibt sich aus den zyklisch versetzten Teilvolumenströmen in den einzelnen Kolben-Zylinder-Baugruppen ein antriebsdrehwinkelgeschwindigkeitsproportionaler Gesamtvolumenstrom, der allerdings nicht pulsationsfrei gefördert werden kann. In sum, the cyclically offset partial volume flows in the individual piston-cylinder assemblies result in a drive rotational angular velocity-proportional overall volume flow, which, however, can not be delivered without pulsation.
Daher ist es die Aufgabe der vorliegenden Erfindung, eine hydraulische Arbeitsmaschine der angegebenen Art mit möglichst einfachen Maßnahmen pulsationsfrei zu gestalten. Therefore, it is the object of the present invention to make a hydraulic working machine of the specified type with the simplest possible measures pulse-free.
Diese Aufgabe wird erfindungsgemäß für eine hydraulische Arbeitsmaschine der angegebenen Art mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst, indem über konstruktiv vorgegebene Antriebsdrehwinkelabschnitte der Kolbenhub konstant gehalten ist. This object is achieved for a hydraulic machine of the type indicated by the characterizing features of
Weitere Merkmale und Vorteile der Erfindung gehen im nachfolgenden aus der Beschreibung mehrerer Ausführungsbeispiele anhand von fünf Zeichnungen hervor.Further features and advantages of the invention will become apparent hereinafter from the description of several embodiments with reference to five drawings.

Es gilt somit die Gleichung: The equation thus applies:
Ebenso ist jede Hubkurve h(φ) dadurch charakterisiert, dass zu jeder Drehwinkelstellung φ die Summe aller in dieser Drehwinkelstellung φ negativen Anstiegsfunktionswerte hi'(φ) der Kolbenhübe i, n konstant ist.Similarly, each lift curve h (φ) is characterized in that at any angular position φ, the sum of all h in this angular position φ negative slope function values i '(φ) of the piston strokes i, n is constant.
Es gilt somit die Gleichung: The equation thus applies:
Weiterhin umfasst jede abgebildete Hubkurve h(φ) einen ersten Abschnitt A, in welchem die Hubkurve ihr Minimum aufweist und betragsmäßig konstant mit einer Steigung von Null und damit steigungsfrei verläuft, sodass unter Rückbezug auf die

Eine derartige Arbeitsmaschine eignet sich in idealer Weise für eine elektrohydraulische Bremsanlage, wozu der Rotor der erfindungsgemäße hydraulischen Arbeitsmaschine, ohne die Zwischenschaltung eines Getriebes, direkt mit einem Elektromotor als Antriebsmaschine zu kombinieren ist, sodass ein elektrohydraulischer Aktuator entsteht, der als Druck- und Volumenquelle für eine elektrohydraulische Bremsanlage vorzüglich geeignet ist. Bevorzugt wird dabei ein bürstenloser, elektronisch kommutierter Elektromotor verwendet. Such a machine is ideally suited for an electro-hydraulic brake system, to which the rotor of the hydraulic machine according to the invention, without the interposition of a transmission to combine directly with an electric motor as a prime mover, so that an electro-hydraulic actuator is created as a pressure and volume source for an electro-hydraulic brake system is excellently suitable. Preferably, a brushless, electronically commutated electric motor is used.
Bei einer Verwendung von sechs Kolben lässt sich die Hubkurve dadurch vereinfachen, dass die Längen der beiden Hubkurvenabschnitte mit extremalem Anstiegsfunktionswert gleich null gesetzt werden können, wodurch sich die beiden jeweils anschließenden Übergangsbereiche zu einem zusammenfassen lassen und die Hubkurve somit über lediglich vier unterschiedliche Abschnitte darstellen lässt. When six pistons are used, the lift curve can be simplified by making the lengths of the two extreme rise function stroke sections equal to zero, allowing the two respective transition areas to be combined to form the lift curve over only four distinct sections ,
Als weitere Variante ist es möglich, zwei erfindungsgemäße Arbeitsmaschinen so zu kombinieren, dass sie sich einen gemeinsamen Rotor und eine gemeinsame Kurvenscheibe teilen. As a further variant, it is possible to combine two machines according to the invention so that they share a common rotor and a common cam.
