La position de fonctionnement de l'électrode mobile (18) peut être ajustée au moyen de l'anneau de réglage (31) pour compenser les tolérances des pièces coopérantes. Le doigt mobile (17) est entraîné par le régulateur centrifuge (19) en fonction de la ligne caractéristique du point d'allumage qui a été obtenue électroniquement, ce qui permet une réduction du diamètre du distributeur (10).A distributor (10) provided with an electronic device for adjusting the ignition point comprises a high-voltage distributor (15 to 18) driven in synchronous rotation with the motor by means of the shaft (13) and whose movable finger (17) can be locked continuously and at a determined angle on a disc (23) of the sleeve (20) of the centrifugal regulator (19). The operating position of the movable electrode (18) can be adjusted by means of the adjusting ring (31) to compensate for the tolerances of the cooperating parts. The movable finger (17) is driven by the centrifugal regulator (19) according to the characteristic line of the ignition point which has been obtained electronically, which allows a reduction in the diameter of the distributor (10).

Description

Zündeinrichtung für Brennkraftmaschinen Ignition device for internal combustion engines
Stand der TechnikState of the art
Bei bekannten Zündeinrichtungen erreicht man die Zündverstellung über Fliehkraft- und Unterdruckvorrichtungen des Zündverteilers. Gleichzeitig wird durch den Fliehkraftversteller der Verteilerläufer nachgeführt, d.h. der Läufer hat über den gesamten Drehzahlbereich die gleiche Stellung zur Kappenelektrode. Mithin kann der Durchmesserdes Hochspannungsverteilers verhältnismäßig klein sein. Darüber hinaus müssen die Läuferelektrode und die Kappenelektroden des Hochspannungsverteilers derart bemessen sein, daß ein Überschlag des Zündfunkens bei allen vorgegebenen Zündverstellwinkeln mit Sicherheit erfolgt, gleichzeitig aber auch ein Überschlag zu einer falschen Elektrode (falschen Zylinder) ausgeschlossen ist.In known ignition devices, the ignition timing is achieved via centrifugal and vacuum devices of the ignition distributor. At the same time, the centrifugal adjuster tracks the distributor rotor, i.e. the rotor has the same position in relation to the cap electrode over the entire speed range. Thus, the diameter of the high voltage distributor can be relatively small. In addition, the rotor electrode and the cap electrodes of the high-voltage distributor must be dimensioned in such a way that the spark overturns with certainty at all predetermined ignition timing angles, but at the same time a flashover to the wrong electrode (wrong cylinder) is impossible.
Bei vollelektronischer Zündverstellung wird dies elektronisch bewerkstelligt, weshalb die Zündauslösung vom Fliehkraftversteller getrennt sein muß. Durch diese not wendige Trennung des Fliehkraftverstellers von der Auslösung wird jedoch erreicht, daß die Nachführung nicht mehr wirksam ist; dies bedingt eine Vergrößerung des Durchmessers des Hochspannungsverteilers. Ein im Durchmesser größerer Hochspannungsverteiler ist jedoch deshalb problematisch, weil die geforderte Zugänglichkeit au den einzelnen Aggregaten im Motorraum bei den ohnehin zumeist beengten Platzverhältnissen problematisch ist.With fully electronic ignition adjustment, this is done electronically, which is why the ignition must be separated from the centrifugal force adjuster. Because of this distress agile separation of the centrifugal force adjuster from the release is achieved, however, that the tracking is no longer effective; this requires an increase in the diameter of the high-voltage distributor. A high-voltage distributor with a larger diameter is problematic, however, because the required accessibility to the individual units in the engine compartment is problematic given the usually cramped space conditions.
Vorteile der ErfindungAdvantages of the invention
Mit der Zündeinrichtung für Brennkraftmaschinen nach der Erfindung wird das im Stand der Technik dargelegte Problem gelöst. Der Erfindung liegt der Gedanke zugrunde, den Verteilerläufer entsprechend der elektronisch erzeugten Zündverstellinie nachzuführen.The ignition device for internal combustion engines according to the invention solves the problem set out in the prior art. The invention is based on the idea of tracking the distributor rotor in accordance with the electronically generated ignition adjustment line.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben. Mit der Weiterbildung der Zündeinrichtung nach Anspruch 3 ist eine Justierung des Verteilerläufers möglich. Wird die Einrichtung nach Anspruch 5 und insbesondere nach Anspruch 6 weitergebildet, so lassen sich hierdurch alle Toleranzen der zusammenwirkenden Teile bis auf die Einstelltoleranz ausschalten. Hierdurch erhält man eine höhere Spannungsfestigkeit des Hochspannungsverteilers.Advantageous developments of the invention are described in the subclaims. With the development of the ignition device according to claim 3, an adjustment of the distributor rotor is possible. If the device is further developed according to claim 5 and in particular according to claim 6, all tolerances of the interacting parts can be switched off except for the setting tolerance. This results in a higher dielectric strength of the high-voltage distributor.

Im Gehäuse 11 sind eine Antriebswelle 13 und ein Induktionsgeber 14 gelagert, der Impulse erzeugt und diese einem nicht dargestellten Schaltgerät zur Verarbeitung zuleitet. In der Kappe 12 sind Festelektroden 15 entsprechend der Zylinderzahl der Brennkraftmaschine und eine Mittelelektrode 16 eingeformt.1 shows an ignition distributor 10 of an ignition device for internal combustion engines with an electronic system for adjusting the ignition timing, with a pot-shaped housing 11 fastened to the engine block (not shown) and a cap 12 made of insulating material. A drive shaft 13 and an induction transmitter 14 are mounted in the housing 11, which generates pulses and feeds them to a switching device (not shown) for processing. Fixed electrodes 15 corresponding to the number of cylinders of the internal combustion engine and a central electrode 16 are molded into the cap 12.
Ein Verteilerläufer 17 führt die Hochspannung der Mittelelektrode 16 über eine Läuferelektrode 18 den einzelnen Festelektroden 15 und den mit diesen verbundenen, nicht gezeichneten Zündkerzen zu.A distributor rotor 17 supplies the high voltage of the center electrode 16 to the individual fixed electrodes 15 and the spark plugs (not shown) connected to them via a rotor electrode 18.
Ein Fliehkraftversteller 19 ist mit der Antriebswelle 13 verbunden und über ein Federpaar 21 mit einer am Endabschnitt 22 der Antriebswelle 13 gelagerten Mitnehmerhülse 20 gekuppelt. An dieser ist eine Platte 23 mit drei Innengewinden 2\ (von denen nur eines sichtbar ist) durch Verstemmen unlösbar verbunden.A centrifugal adjuster 19 is connected to the drive shaft 13 and coupled via a pair of springs 21 to a driving sleeve 20 mounted on the end section 22 of the drive shaft 13. At this, a plate 23 with three internal threads 2 \ (only one of which is visible) is permanently connected by caulking.
Der Verteilerläufer 17 hat mehrere sich auf der Platte 23 abstützende Vorsprünge 25 und mehrere Flanschabschnitte 26 mit jeweils einer eingeformten Buchse 27. Jede Buchse hat ein Langloch 28, durch das der Gewinde bolzen 29 einer Kopfschraube 30 hindurchsteckbar ist, so daß diese in das Innengewinde 24 der Platte 23 einund ausschraubbar ist. Die Längsausdehnung des Langloches 28 ist dabei derart, daß bei gelöster Kopfschraube 30 der Verteilerläufer 17 bezüglich der Antriebswelle 13 und koaxial zu dieser um einige Winkelgrade sich stufenlos verstellen läßt und die eingestellte Winkellage durch die Kopfschraube 30 feststellbar ist.The distributor rotor 17 has a plurality of projections 25 which are supported on the plate 23 and a plurality of flange sections 26, each with a molded-in bushing 27. Each bushing has an elongated hole 28 through which the thread bolt 29 of a cap screw 30 can be inserted so that it can be screwed into and out of the internal thread 24 of the plate 23. The longitudinal extension of the elongated hole 28 is such that when the cap screw 30 is loosened, the distributor rotor 17 can be steplessly adjusted by a few angular degrees with respect to the drive shaft 13 and coaxially therewith and the set angular position can be determined by the cap screw 30.
Ein hülsenförmiger Einstellring 31 aus Metall weist an seinem einen Endabschnitt eine Innennut 32 und eine Nase 33 auf, die mittels einer Senkschraube 35 befestigt ist und in axialer Richtung vom Einstellring 31 absteht. Der gegenüberliegende Abschnitt des Einstellringes 31 weist eine Aussparung 36 auf, in der ein radial nach innen weisender Vorsprung 34 mittels einer Senkschraube 35 befestigt ist.A sleeve-shaped adjusting ring 31 made of metal has at its one end section an inner groove 32 and a lug 33 which is fastened by means of a countersunk screw 35 and protrudes from the adjusting ring 31 in the axial direction. The opposite section of the adjusting ring 31 has a recess 36 in which a radially inward projection 34 is fastened by means of a countersunk screw 35.
Der Einstellring 31 dient zur Justierung der Läuferelektrode 18 und wird hierfür derart auf den Rand 37 des Gehäuses 11 aufgesetzt, daß die Nase 33 in eine Nut 38 des Randes 37 eingreift. Danach wird die Antriebswelle 13 in Auslösestellung (Zündzeitpunkt-Stellung) gebracht und der von der Platte 23 gelöste Verteilerläufer 17 soweit gedreht, bis dessen Läuferelektrode 18 am Vorsprung 34 zum Anliegen kommt. Diese Funktionslage wird mittels der Schraube 30 arretiert. Durch diese Justierung sind alle Toleranzen der zusammenwirkenden Elemente ausgeschaltet. The adjusting ring 31 serves to adjust the rotor electrode 18 and is placed on the edge 37 of the housing 11 in such a way that the nose 33 engages in a groove 38 of the edge 37. Thereafter, the drive shaft 13 is brought into the release position (ignition timing position) and the distributor rotor 17 detached from the plate 23 is rotated until its rotor electrode 18 comes to rest on the projection 34. This functional position is locked by means of the screw 30. This adjustment eliminates all tolerances of the interacting elements.
