Beschreibung der AusführungsbeispieleDescription of the embodiments

Ein Gehäuse 11 eines unterbrecherlosen Zündverteilers für elektronische Zündeinrichtung ist einer strich­ liert dargestellten Brennkraftmaschine 10 lösbar fest­ gelegt. In einer Hülse 12 des Gehäuses 11 sind zwei La­ gerbuchsen 13 und eine Ringdichtung 14 für eine Welle 15 befestigt, die durch eine nicht dargestellte Nocken­ welle der Brennkraftmaschine 10 antreibbar ist.A housing 11 of an uninterruptible ignition distributor for electronic ignition device is a dashed line internal combustion engine 10 releasably fixed. In a sleeve 12 of the housing 11 , two La gerbuchsen 13 and an annular seal 14 for a shaft 15 are attached, the shaft of the internal combustion engine 10 is driven by a cam, not shown.

Eine am Gehäuse 11 befestigbare Isolierkappe 16 hat mehrere Festelektroden 17 (von denen nur eine darge­ stellt ist) und eine Mittelelektrode 18, welche die Hochspannung mittels einer Elektrode 19 eines Läufers 20 jeweils einer Festelektrode 17 zuführt. An dem aus Kunststoff hergestellten Läufer 20 ist eine Ring­ platte 22 eines magnetisch leitfähigen Blendenrotors 21 mittels Nietung unlösbar befestigt, und mehrere ra­ diale Blenden 23 des Blendenrotors 21 wirken mit einem Hallgeber 24 (Erregerquelle mit Halbleiter-Geberelement) in bekannter Weise zusammen. An attachable to the housing 11 insulating cap 16 has a plurality of fixed electrodes 17 (only one of which is shown) and a center electrode 18 , which supplies the high voltage by means of an electrode 19 of a rotor 20 to a fixed electrode 17 . On the runner 20 made of plastic, a ring plate 22 of a magnetically conductive aperture rotor 21 is permanently attached by riveting, and several ra diale apertures 23 of the aperture rotor 21 interact with a Hall sensor 24 (excitation source with semiconductor sensor element) in a known manner.

Anstatt der Nietung kann die Befestigung des Läufers 20 an der Ringplatte 22 des Blendenrotors 21 auch durch andere Befestigungsarten erfolgen, wie beispielsweise Kleben, Verstemmen mittels Ultraschall, hochgebogene Lappen des Rotors, Verschrauben, Verspannen mittels Klemmscheiben u.dgl.Instead of riveting, the rotor 20 can be fastened to the ring plate 22 of the diaphragm rotor 21 by other types of fastening, such as, for example, gluing, caulking by means of ultrasound, curved lobes of the rotor, screwing, bracing by means of clamping disks and the like.

Der Endabschnitt der Welle 15 ist ein im Durchmesser kleinerer Zapfen 25, der zum einen eine kegelstumpf­ förmige Fläche 26 (Fase) aufweist und zum andern mit der Welle 15 eine Ringschulter 27 bildet. Die Ring­ platte 22 des Blendenrotors 21 hat einen axialen Ring­ kragen 28, der auf dem Zapfen 25 aufgeschoben ist und dessen Stirnfläche sich an der Ringschulter 27 ab­ stützt. Eine Stützringscheibe 29 ist auf der Stirnseite der Hülse 12 befestigt, und zwischen der Stützringscheibe 29 und der Unterseite der Ringplatte 22 des Blendenrotors 21 sind eine Anlaufscheibe 30 und eine Ausgleichsscheibe 31 eingefügt. Die Festlegung des Läufers 20 auf dem Zapfen 25 der Welle 15 erfolgt durch eine Schweißnaht 32 in der durch die kegelstumpfförmige Fläche 26 und den Ringkragen 28 gebildeten Ringnut. Anstelle der Schweißnaht 32 sind einzelne Schweißpunkte möglich.The end section of the shaft 15 is a pin 25 with a smaller diameter, which on the one hand has a frustoconical surface 26 (chamfer) and on the other forms an annular shoulder 27 with the shaft 15 . The ring plate 22 of the diaphragm rotor 21 has an axial ring collar 28 , which is pushed onto the pin 25 and the end face of which is supported on the annular shoulder 27 . A support washer 29 is attached to the end face of the sleeve 12 , and a thrust washer 30 and a shim 31 are inserted between the support washer 29 and the underside of the ring plate 22 of the orifice rotor 21 . The rotor 20 is fixed on the journal 25 of the shaft 15 by a weld seam 32 in the annular groove formed by the frustoconical surface 26 and the annular collar 28 . Instead of the weld seam 32 , individual weld spots are possible.

Im zweiten Ausführungsbeispiel in Fig. 2 ist der Läu­ fer mit 40 bezeichnet, und der den Endabschnitt der Welle 15 bildende Zapfen 45 hat an seiner Mantelfläche einen Zahnring 44. An der Ringplatte 42 des Blendenrotors 41 ist ein aus Kunststoff oder Metall hergestellter Ring 43 durch Bördeln befestigt, dessen Innenbereich auf dem Zahn­ ring 44 formschlüssig aufgepreßt ist und durch Verstemmen in der Nut am Zapfen 45 unlösbar mit der Welle 15 befestigt ist. In the second embodiment in FIG. 2, the rotor is designated 40 , and the pin 45 forming the end section of the shaft 15 has a toothed ring 44 on its outer surface. On the ring plate 42 of the diaphragm rotor 41 , a ring 43 made of plastic or metal is fastened by flanging, the inner area of which is pressed onto the toothed ring 44 in a form-fitting manner and is permanently attached to the shaft 15 by caulking in the groove on the pin 45 .

Die Befestigung des Ringes 43 an der Ringplatte 42 kann anstatt Bördeln auch durch Schweißen oder Löten erfolgen.The attachment of the ring 43 to the ring plate 42 can also be done by welding or soldering instead of flanging.
