Description

Vorrichtung zur elektrischen Messung des Olstandes in Kraftfahrzeugmotoren Bekanntlich ist die Messung des Olstandes in Kraftfahrzeugmotoren nur bei stillstehendem Motor zweckmäBig. Bei der Verwendung von elektrischen Olstandmessern bleibt die Meßeinrichtung aber auch bei laufendem Motor in Betrieb, wenn nicht eine besondere Ausschaltvorrichtung vorgesehen ist, deren Bedienung aber leicht vergessen wird.Device for the electrical measurement of the oil level in motor vehicle engines As is well known, the measurement of the oil level in motor vehicle engines is only possible when the engine is at a standstill Engine expedient. When using electric oil level meters, the Measuring device also in operation with the engine running, if not a special one Switch-off device is provided, but its operation is easily forgotten.

Die Erfindung setzt sich daher zum Ziel, eine selbsttätige Ausschaltung der elektrischen Olstandsmeßeinrichtung beim Anlaufen des Motors zu schaffen, jedoch ohne Aufwand besonderer Einrichtungen. The aim of the invention is therefore to automatically switch off to create the electrical oil level measuring device when starting the engine, however without the need for special facilities.

Nach der Erfintdung wird die elektrische Olstandsmeßeinrichtung der Ladekontrolleuchte parallel geschaltet und damit der Stromschalter des Lichtmaschinenreglers zugleich zum An-und Abschalten der Meßeinrichtung ausgenutzt. According to the invention, the electrical oil level measuring device is the Charging indicator light connected in parallel and thus the power switch of the alternator regulator used at the same time to switch the measuring device on and off.

Die Zeichnung zeigt die Schaltung nach der Erfindung innerhalb des in Frage kommenden Teils des Bordnetzes. The drawing shows the circuit according to the invention within the eligible part of the electrical system.

Die Fahrzeugbatterie 1 ist mit ihrem negativen Pol sowohl an » Masse « 2 als auch auch den Anker Anker der Lichtmaschine 4 angeschlossen. Von dem Anker geht eine Verbindungsleitung über die Stromspule 5 des Lichtmascliinenreglers 6 zur Stromspule 7 des edektromagnetischen Schalters 8, dessen Gegenkontakt 9 einerseits mit dem Pluspol der Fahrzeugbatterie, andererseits mit dem Zündschloß 10 verbunden ist. The negative pole of the vehicle battery 1 is both connected to ground «2 as well as the armature armature of the alternator 4 connected. From the anchor a connecting line goes through the current coil 5 of the light mask regulator 6 to the current coil 7 of the electromagnetic switch 8, the mating contact 9 of which on the one hand connected to the positive pole of the vehicle battery, on the other hand to the ignition lock 10 is.

Zwischen dem Zündschloß und der Stromspule 5 des Reglers liegt die Ladekontrolleuchte 11 und parallel zu dieser der Schwimmergeber 12 und das Anzeigegerät 13 für den Olstand in Hintereinanderschaltung.Between the ignition lock and the current coil 5 of the controller is the Charge control lamp 11 and parallel to this the float transmitter 12 and the display device 13 for the oil stand in series.

Nach Einschalten des Zündschlosses 10 liegt die Meßeinrichtung 12,13 ebenso wie die Ladekontrollleuchte 11 an der Batteriespannung. Der Olstand kann an dem Meßgerät 13 abgelesen werden. Dabei ist der ohmsche Widerstand des stillstehenden Tankers 3 der Lichtmaschine zu vernachlässigen. Wird dann der Motor in Betrieb gesetzt, so erreicht die mit ihm gekuppelte Lichtmaschine schon bei einer Drehzahl, die unter der Betriebsdrehzahl liegt, eine Klemmenspannung, die gleich hoch, aber entgegengesetzt gepolt wie die Batteriespannung ist. Nunmehr wird die Schalterspule 7 mit Strom beschickt, da sie über das Reglergehäuse und die Spannungsspule 14 mit der Masse 2 und damit mit der Lichtmaschine 4 verbunden ist. Die Kontaktes, 9 des Kontrollschalters werden geschlossen, womit die Ladekontrollampe zum Erlöschen gebracht wird. Hierdurch wird aber auch die parallel liegende Meßeinrichtung 12,13 außer Betrieb gesetzt.After switching on the ignition lock 10, the measuring device 12, 13 is located just like the charge control lamp 11 on the battery voltage. The oil stand can can be read on the measuring device 13. Here is the ohmic resistance of the stationary Tankers 3 neglect the alternator. If the engine is then put into operation, so the alternator coupled with it already reaches at a speed that under the operating speed, a terminal voltage that is the same but opposite polarized like the battery voltage. Now the switch coil 7 is energized charged, as it is connected to the ground via the controller housing and the voltage coil 14 2 and is thus connected to the alternator 4. Contact, 9 of the control switch are closed, which causes the charge control lamp to go out. Through this but the parallel measuring device 12, 13 is also put out of operation.
