für elektrohydraulische Bauteile – wie insbesondere
elektrohydraulische Ventile – angeflanscht ist, und zum
Antrieb einer Radialkolbenpumpe, umfassend zwei einander gegenüber
liegende Pumpenkolben, dient. In diesem Zusammenhang ist typischerweise
jeweils eine Kolbenpumpe jeweils einem Bremskreis der Fahrzeugbremsanlage
zugeordnet. Auf einer, dem Elektromotor gegenüber liegenden,
Seite ist an der Hydraulikeinheit eine Elektronikeinheit (ECU, Regeleinheit)
befestigt, welche zur elektrischen Ansteuerung vom Elektromotor
sowie der elektrohydraulischen Ventile dient. Vereinfacht ausgedrückt
sind die verschiedenen Module in mehreren Ebenen gewissermaßen übereinander
geschichtet angeordnet, was erfordert, das jedes Modul als eigenständig
handhabbare Baueinheit mit einem Gehäuse und mit mechanischen
und elektrischen Schnittstellen zum Anschluss an ein oder mehrere Nachbarmodule

Es ist eine Aufgabe der vorliegenden Erfindung, ein Fahrzeughydraulikaggregat mit einer Radialkolbenpumpe in abgeänderter Bauweise vorzuschlagen, das eine weitergehende Miniaturisierung ermöglicht.It An object of the present invention is a vehicle hydraulic unit to propose with a radial piston pump in a modified design, which allows for further miniaturization.
Die Aufgabe wird mit Hilfe einer Radialkolbenpumpe gelöst, bei der zwischen Elektromotor und Pumpenkolben ein hohler, motorgetriebener Pumpenrotor versehen ist, welcher eine nach radial innen weisende Steuerkontur zur Beaufschlagung der Pumpenkolben aufweist, und dass der Rotor den Aufnahmekörper radial außen umgreift, welcher die Pumpenkolben, Verdrängungsräume, Kanäle und/oder elektrohydraulisch steuerbaren Ventile aufnimmt. Im Unterschied zu bekannten Exzentergetrieben von Fahrzeughydraulikaggregaten wird eine Pumpenläuferanordnung vorgeschlagen, welche das rotatorisch festgelegte Pumpengehäuse mit dessen hydraulisch wirksamen Bauelementen von außen umgreift. Erfindungsgemäß wird von einfachen, wellenfesten Exzenteranordnungen Abstand genommen.The Task is solved with the help of a radial piston pump, at the between electric motor and pump piston a hollow, motor driven Pump rotor is provided, which has a pointing radially inward Control contour for acting on the pump piston has, and that the rotor surrounds the receiving body radially on the outside, which the pump piston, displacement chambers, channels and / or Electro-hydraulically controllable valves absorbs. In difference become known Exzentergetrieben of vehicle hydraulic units proposed a pump rotor assembly which the rotational fixed pump housing with its hydraulically effective Surrounding components from the outside. According to the invention from simple, wave-proof eccentric arrangements refrained.
Der Pumpenrotor ist drehfest mit einem Rotor des Elektromotors verbunden, der bevorzugt Permanentmagneten trägt. Radial außerhalb des Rotors befinden sich statisch festgelegte Wicklungen, die ein Bestandteil der ECU sind. Durch die radial äußere Anordnung der Wicklungen kann deren Wärmeentwicklung im Betrieb effektiv an die Umgebung abgegeben werden.Of the Pump rotor is rotatably connected to a rotor of the electric motor, which preferably carries permanent magnets. Radially outside of the rotor are statically fixed windings, the one Part of the ECU. Due to the radially outer arrangement The windings can effectively heat their heat during operation be delivered to the environment.
In weiterer Ausgestaltung der Erfindung hat die Steuerkontur eine periodisch-sinusförmige Formgebung zur Zwangssteuerung der Pumpenkolben. Das Fördervolumen der Pumpenkolben wird durch den konkreten Verlauf der Steuerkontur, wie insbesondere durch deren Steigung, sowie durch die Antriebsdrehzahl vom Pumpenrotor bestimmt.In Another embodiment of the invention, the control contour has a periodic-sinusoidal Shaping for positive control of the pump piston. The delivery volume the pump piston is determined by the specific course of the control contour, in particular by their slope, as well as by the drive speed determined by the pump rotor.
In bevorzugter Ausführungsform der Erfindung ist die Steuerkontur so ausgebildet, dass pro Umdrehung an jedem Pumpenkolben mehrere Phasenwechsel vollzogen werden, so dass jeder Pumpenkolben je Antriebsdrehung mehrfach wechselnde Ansaug- und Ausschubbewegungen ausführt. Durch die Übersetzung wird es ermöglicht, die Laufruhe des Aggregates zu erhöhen, weil mit vergleichsweise geringen Drehzahlen des Elektromotors hohe Drücke und Förderströme erzielt werden können.In preferred embodiment of the invention is the control contour designed so that per revolution on each pump piston several Phase changes are performed so that each pump piston per drive rotation repeatedly changing suction and Ausschubbewegungen performs. The translation will allow the Smooth running of the unit increase, because with comparatively low speeds of the electric motor high pressures and flow rates can be achieved.
In vorteilhafter Ausgestaltung der Erfindung ist der Aufnahmekörper rotationssymmetrisch ausgebildet, und nimmt in entsprechenden Aufnahmebohrungen mehrere stromlos offene und stromlos geschlossene Ventile auf. Die Aufnahmebohrungen für die Ventile sind auf einer oder auf mehreren Stirnseiten vom Pumpengehäuse sowie rechtwinklig zu Aufnahmebohrungen für die Pumpenkolben angeordnet. Die Aufnahmebohrungen der Pumpenkolben sind gegenüber der Steuerkontur platziert.In Advantageous embodiment of the invention is the receiving body formed rotationally symmetrical, and takes in corresponding mounting holes several normally open and normally closed valves on. The Mounting bores for the valves are on one or on several end faces of the pump housing and at right angles arranged to receiving bores for the pump piston. The Mounting bores of the pump pistons are opposite to the control contour placed.
