Abstract

The slot-type rotor (19) is provided with a hole (22) concentric to the shaft (10) and characterized by a number of recesses (31), and the hole-plate (13) fixed to the shaft (10) has a collar (15) corresponding to the hole (22), from the exterior (32) of which collar several protrusions (30) project to engage by virtue of their shape in the recesses (31). The hole-plate (13) is screwed to the distributor rotor (23), the slot-type rotor being inserted between. The positive linking of the slot-type rotor (19) to the distributor rotor (23) ensures perfect entrainment of the former by the shaft (10), even in the event of the screw connection becoming accidentally loose.

Description

Zündverteiler mit Hallgeber für Zündeinrichtungen von BrennkraftmaschinenIgnition distributor with Hall sender for ignition devices of internal combustion engines

Stand der TechnikState of the art

Die Erfindung betrifft einen Zündverteiler mit Hallgeber für Zündeinrichtungen von Brennkraftmaschinen nach der Gattung des Anspruchs 1. Bei derartigen Zündverteilern ist das Loch des Blendenrotors vom Hallgeber kreisflächenförmig und die Welle hat einen Stirnzapfen, an dem sich der Blendenrotor zentriert und axial abstützt. Durch Bördeln des Stirnzapfens wird der Blendenrotor am Ring und mithin an der Welle kraftschlüssig festgelegt.The invention relates to an ignition distributor with Hall sender for ignition devices of internal combustion engines according to the preamble of claim 1. In such ignition distributors, the hole in the diaphragm rotor from the Hall sender is circular and the shaft has an end pin on which the diaphragm rotor is centered and axially supported. By flanging the front pin, the diaphragm rotor is non-positively attached to the ring and therefore to the shaft.

Lockert sich jedoch die kraftschlüssige Verbindung, so führt dies zu einem Winkelversatz des Blendenrotors zur Magnetschranke und des Läufers zu den Festelektroden, so daß eine einwandfreie Funktion der Zündungsauslösung und der Hochspannungsverteilung nicht erfolgt und u. U. den Ausfall der Zündanlage verursachen. Vorteile der ErfindungHowever, the non-positive connection loosens, this leads to an angular offset of the diaphragm rotor to the magnetic barrier and the rotor to the fixed electrodes, so that the ignition triggering and the high-voltage distribution do not function properly, and u. U. cause the ignition system to fail. Advantages of the invention

Mit dem Zündverteiler mit Hallgeber für Zündeinrichtungen von Brennkraftmaschinen nach der Erfindung wird das im vorerwähnten Stand der Technik dargelegte Problem mit technisch einfachen Mitteln gelöst. Durch die formschlüssige, drehgesicherte Drehmitnahme des Blendenrotors durch die Welle ist auch bei einem allfälligen Lockern des Blendenrotors dessen Winkelversatz ausgeschlossen, so daß weder die Zündauslösung noch die Hochspannungsverteilung beeinträchtigt werden.With the ignition distributor with Hall sender for ignition devices of internal combustion engines according to the invention, the problem set out in the aforementioned prior art is solved with technically simple means. Due to the positive, rotationally secured rotation of the orifice rotor by the shaft, even if the orifice rotor is loosened, its angular misalignment is excluded, so that neither the ignition triggering nor the high-voltage distribution are impaired.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben. Mit Anspruch 2 ist der Weg zu einer technisch einfachen Ausführung gewiesen. Mit Anspruch 3 wird der Formschluß durch eine Nut-Feder-Verbindung erreicht. Mit Anspruch 4 und Anspruch 5 sind eine sicherwirkende Schraub- bzw. Klebeverbindung aufgezeigt.Advantageous developments of the invention are described in the subclaims. Claim 2 shows the way to a technically simple implementation. With claim 3, the positive connection is achieved by a tongue and groove connection. With claim 4 and claim 5 a safe-acting screw or adhesive connection are shown.
