Schmiermittels für eine oder mehrere ausgewählte Meßstellen im Schmierkreislauf.
Aus diesem Kennfeld sind vom Betriebszustand des Motors Solldruckwerte des

Fig.1 zeigt einen Druckregelkreis 2, z. B. für eine von einem Verbrennungsmotor VM
angetriebene Schmiermittelpumpe 1, deren Fördermenge mittels eines Stellgliedes
13 veränderbar ist. Diese Schmiermittelpumpe 1 speist den Schmierkreislauf
DK, der z. B. über eine Drosselstelle zum Rücklauf R entlastet wird. Er ist in den
Fig. 1 und Fig. 2 nur schematisch ohne Einzelheiten dargestellt.
Der zugehörige Druckregelkreis 2 ist wie folgt aufgebaut. Solldruckwerte psw an
einer ausgewählten Meßstelle M, z. B. eines Schmierkreislaufes SK, sind in einem
Kennfeld 40 gespeichert und können bei Eingabe der Parameter, z. B. der Motordrehzahl
n, der Last L und der Motortemperatur T, des momentanen Betriebszustandes
eines Verbrennungsmotors 35, aus diesem ausgelesen werden. Fig.1 shows a
The associated
Bei einem Vergleich des ausgelesenen Soll-Druckwertes psw und des Ist-Druckes pi
an der ausgewählten Meßstelle M des Schmierkreislaufes SK wird in einer Einheit
41 eine Regelabweichung RA ermittelt und einer Ansteuervorrichtung 42 zugeführt.
. Bei vorhandener Regelabweichung RA wird das Stellglied 13 über Signale S13 der
Ansteuervorrichtung 42 verlagert, wobei eine Mehr- oder Minderförderung eingestellt
wird. Dies erfolgt, bis der Ist-Druck pi des Öls an der ausgewählten Meßstelle M im
Schmierkreislauf SK dem betriebszustandsabhängigen, aus dem Kennfeld 40 ausgelesenen
Soll-Druckwert psw entspricht.
An einer besonders gefährdeten Lagerstelle VL des Verbrennungsmotors VM kann
vorteilhaft die Temperatur TL erfaßt werden, siehe Fig. 2. Überschreitet die Temperatur
TL einen Grenzwert, so wird eine Maximalförderung Fmax der Schmiermittelpumpe
eingestellt wird. Die übrigen Parameter des Betriebszustandes des Verbrennungsmotors
VM bleiben in diesem Fall ohne Einfluß auf die eingestellte maximale
Fördermenge Fmax.
Die erfindungsgemäße Anordnung zum Regeln der Schmierung, siehe Fig. 1, gemäß
dem Verfahren weist folgende Baugruppen auf. Ein Kennfeld 40 enthält
betriebszustandsabhängige Soll-Druckwerte psw von einer oder mehreren
ausgewählten Meßstellen M des Schmierkreislaufes SK, die in Abhängigkeit von den
eingangsseitig anliegenden Signalen des Betriebszustandes abrufbar sind.
Einer Einheit 41 liegen eingangsseitig Signale des jeweiligen Soll-Druckwertes psw
und des momentanen Ist-Druckes pi an, aus denen ein Signal der Regelabweichung
RA gebildet wird. Eine Ansteuereinrichtung 42 speist entsprechend dem
Signal der Regelabweichung RA das Stellglied 13 und bestimmt damit dessen
Wirkrichtung und die Stellung des Regelhebels der Schmiermittelpumpe 1.
Vorteilhaft ist eine Einheit 43, siehe Fig. 2, zum Auswerten der Temperatur TL an
einer besonders gefährdeten, am höchsten belasteten Lagerstelle VL vorhanden.
Beim Überschreiten der zulässigen Temperatur TL wird ein Signal Fmax zum Einstellen
einer Maximalförderung der Schmiermittelpumpe 1 gebildet.
Dieses Signal Fmax liegt zusammen mit dem Signal der Regelabweichung RA einer
Vorrangschaltung 44 eingangsseitig an, wobei beim Anliegen des Signals Fmax nur
dieses ausgangsseitig wirksam ist, womit eine Maximalförderung der Schmiermittelpumpe
eingestellt wird. In a comparison of the read target pressure value p sw and the actual pressure p i at the selected measuring point M of the lubrication circuit SK, a control deviation RA is determined in a
