Description

Die Erfindung bezieht sich auf eine Vorrichtung mit den Merkmalen des Oberbegriffs von Patentanspruch 1.The invention relates to a device with the features of the preamble of claim 1.

Bekannte Vorrichtungen dieser Art bestehen aus Schraubverbindungen der Zündspule mit dem Zylinderkopf und sind in der DE 39 37 828 C1 und EP 0 454 598 A1 beschrieben. Hierzu ist vorzugsweise der Magnetkern der Zündspule mit zusätzlichen Befestigungsöffnungen versehen, durch die hindurch eine Befestigungsschraube in den Zylinderkopf eingeschraubt ist. Die vorzugsweise zwei oder vier Befestigungsschrauben erfordern bei der Montage und Demontage der Vorrichtung einen besonderen Aufwand. Zudem erhöhen sie das Gewicht des Systems und führen aufgrund der seitlichen Anordnung der Befestigungsöffnungen gegenüber der Zündspule zu einer zusätzlichen mechanischen Belastung aufgrund beim Einsatz auftretenden Schwingungen.Known devices of this type consist of screw connections between the ignition coil and the cylinder head and are described in DE 39 37 828 C1 and EP 0 454 598 A1. For this purpose, the magnetic core of the ignition coil is preferably provided with additional fastening openings through which a fastening screw is screwed into the cylinder head. The preferably two or four fastening screws require special effort when assembling and disassembling the device. In addition, they increase the weight of the system and, due to the lateral arrangement of the fastening openings opposite the ignition coil, lead to additional mechanical stress due to vibrations occurring during use.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, die sich durch einen geringen Montage- und Fertigungsaufwand bei gleichzeitig verringertem Gewicht auszeichnet.The invention has for its object to provide a device of the type mentioned, which is characterized by a low assembly and manufacturing costs while reducing weight.

Die Erfindung löst diese Aufgabe durch die kennzeichnenden Merkmale des Patentanspruchs 1. Im Gegensatz zu den bekannten Vorrichtungen wäre das Einzelspulenzündsystem nunmehr durch den Zündkerzenstecker in seiner Wirklage fixiert. Die Kombination von Reibschluß der elastischen Lagerung und Verrastung mit der Zündkerze ermöglicht es, das System bereits bei Einsetzen in die Durchtrittsöffnung während ein und desselben Arbeitsgangs in seiner Lage zu fixieren. Zusätzliche Befestigungsschrauben oder dgl., die einen separaten Arbeitsgang erfordern, entfallen. Die elastische Lagerung der Zündspule und damit des Einzelspulenzündsystems sorgt darüber hinaus für eine stetige Bedämpfung während des Betriebs der Brennkraftmaschine. Das Fehlen von außen mittig angeordneten Durchtrittsöffnungen für Befestigungsschrauben erhöht die mechanische Stabilität des Gesamtsystems. Die Verrastung des Zündkerzensteckers mit der Zündkerze ist zwar seit langem für Zündkerzenstecker bekannt, die über ein Zündkabel mit einer zentralen Zündspule verbunden sind. Im Unterschied dazu ist der Zündkerzenstecker bei der Erfindung während der Montage i.d.R. nicht sichtbar und das Erreichen der Wirklage auch von außen nicht erkennbar. Hier ermöglicht es die Verrastung mechanisch und akustisch zu erkennen, daß das Einzelspulenzündsystem die vorgesehene Position erreicht hat. Die Verrastung dient somit auch als mechanischer Anschlag für das Einzelspulenzündsystem und damit als Montagehilfe.The invention solves this problem by the characterizing features of patent claim 1. In contrast to the known devices, the single-coil ignition system would be now fixed in its operative position by the spark plug connector. The combination of frictional engagement of the elastic mounting and latching with the spark plug enables the system to be fixed in its position as soon as it is inserted into the passage opening during one and the same operation. Additional fastening screws or the like, which require a separate operation, are not required. The elastic mounting of the ignition coil and thus the single coil ignition system also ensures constant damping during operation of the internal combustion engine. The absence of through openings for fastening screws arranged in the center increases the mechanical stability of the overall system. The locking of the spark plug connector with the spark plug has long been known for spark plug connectors that are connected to a central ignition coil via an ignition cable. In contrast to this, the spark plug connector in the invention is usually not visible during assembly and the reaching of the active position is also not recognizable from the outside. Here the latching makes it possible to recognize mechanically and acoustically that the single-coil ignition system has reached the intended position. The latching also serves as a mechanical stop for the single-coil ignition system and thus as an assembly aid.

Vorteilhafte Ausgestaltung der Erfindung sind Gegenstand der Patentansprüche 2 bis 6 und bieten im wesentlichen folgende zusätzliche Vorteile:Advantageous embodiments of the invention are the subject of claims 2 to 6 and essentially offer the following additional advantages:

Durch den Patentanspruch 2 ergibt sich eine Vereinfachung der Herstellung, da für die elastische Lagerung Rippen vorgesehen sind, die einstückig mit dem Zündkerzenstecker verbunden sind und in einem Herstellungsvorgang gleichzeitig mit dem Zündkerzenstecker gebildet werden. Dies ist gegenüber einer Anordnung von Rippen oder dgl., die mit dem Zylinderkopf verbunden sind, eine zusätzliche Montageerleichterung.Claim 2 simplifies production, since ribs are provided for the elastic mounting, which are connected in one piece to the spark plug connector and are formed simultaneously with the spark plug connector in one production process. This is compared to an arrangement of ribs or the like connected to the cylinder head, an additional ease of assembly.

Durch den Patentanspruch 3 wird die Montage weitererleichtert. Im Gegensatz zu Rippen, die konzentrisch am Umfang des Zündkerzensteckers angeordnet sind, läßt sich durch die axiale Anordnung der Rippen ein Einführen des Einzelspulenzündsystems in die Wirklage mit konstanten oder kontinuierlich zunehmender Einpresskraft erreichen.The assembly is further facilitated by claim 3. In contrast to ribs, which are arranged concentrically on the circumference of the spark plug connector, the axial arrangement of the ribs allows the single-coil ignition system to be introduced into the operative position with a constant or continuously increasing press-in force.

Das im Patentanspruch 4 angegebene Merkmal dient dazu, den Formschluß zwischen Zündkerzenstecker und Zündspule zu erhöhen. Gleichzeitig bleibt die Möglichkeit erhalten, die Achse des Zündkerzensteckers gegenüber der Zündspule zu kippen, wenn dies aufgrund von Fertigungstoleranzen beim Aufstecken des Systems auf die Zündkerze erforderlich ist.The feature specified in claim 4 serves to increase the positive connection between the spark plug connector and the ignition coil. At the same time, the possibility remains to tilt the axis of the spark plug connector with respect to the ignition coil if this is necessary due to manufacturing tolerances when the system is plugged onto the spark plug.

Die Merkmale des Patentanspruchs 5 verringern den Herstellungsaufwand des Systems.The features of claim 5 reduce the manufacturing cost of the system.

Schließlich ergeben sich durch die Merkmale des Patentanspruchs 6 eine zusätzliche Montagehilfe, durch die eine exakte Ausrichtung des Systems in seiner Wirklage erreicht wird.Finally, the features of claim 6 result in an additional assembly aid, by means of which an exact alignment of the system in its operative position is achieved.

Fig. 1 zeigt ein Einzelspulenzündsystem bestehend aus einer Zündspule 1 mit Magnetkern 1' einer Primär- und Sekundärwicklung (nicht dargestellt) sowie einem Zündkerzenstecker 2. Der Magnetkern 1' ist über den Masseanschluß der Sekundärwicklung auf Masse gelegt (nicht dargestellt). In einem Zylinderkopf 3 einer ausschnittsweise dargestellten Brennkraftmaschine mit Ventilen 4 und einem Zylinder 5 sitzt eine Zündkerze 6, die durch das Einzelspulenzündsystem mit Hochspannung versorgt ist.1 shows a single coil ignition system consisting of an ignition coil 1 with a magnetic core 1 'of a primary and secondary winding (not shown) and a spark plug connector 2. The magnetic core 1' is connected to ground via the ground connection of the secondary winding (not shown). A spark plug 6, which is supplied with high voltage by the single-coil ignition system, is seated in a cylinder head 3 of an internal combustion engine with sections 4 and a cylinder 5.

Das Einzelspulenzündsystem ist über den Zündkerzenstecker 2 in einer Durchtrittsöffnung 7 des Zylinderkopfs 3 elastisch gehalten und durch eine Rastverbindung zwischen einem Kontaktteil 8 der Zündkerze 6 unter dem Zündkerzenstecker 2 axial fixiert. Die Rastverbindung zwischen Zündkerze und Zündkerzenstecker 2 ist in an sich bekannter Weise aufgebaut und besteht im wesentlich aus Flachbandfeder 9 im Zündkerzenstecker 2, die einen Absatz 10 des Kontaktteils 8 hintergreift.The single-coil ignition system is held elastically via the spark plug connector 2 in a passage opening 7 of the cylinder head 3 and is axially fixed under the spark plug connector 2 by a snap connection between a contact part 8 of the spark plug 6. The snap-in connection between the spark plug and the spark plug connector 2 is constructed in a manner known per se and essentially consists of a flat ribbon spring 9 in the spark plug connector 2, which engages behind a shoulder 10 of the contact part 8.

Zur elastischen Lagerung ist der Zündkerzenstecker an seiner Außenseite mit vier Rippen 11 versehen, die in axialer Richtung verlaufen und die in Fig. 2 in der Draufsicht dargestellt sind. Die Rippen 11 sind einstückig mit der Außenwand 2' des Zündkerzensteckers 2 und bestehen wie diese aus elastischem elektrisch isolierendem Material, z.B. Silicon.For elastic mounting, the spark plug connector is provided on its outside with four ribs 11 which run in the axial direction and which are shown in plan view in FIG. 2. The ribs 11 are integral with the outer wall 2 'of the spark plug connector 2 and, like this, consist of elastic, electrically insulating material, e.g. Silicone.

Zwischen einem nach unten gezogenen Hochspannungsan schlusses 12 der Zündspule und dem diesen innen und außen umgebenden und mittels Presspassung darin gehaltenen Zündkerzenstecker 2 sitzt ein O-Ring 13, der in einer Ringnut des Zündkerzensteckers gehalten ist. Damit wird die Steifigkeit von Zündspule 1 und Zündkerzenstecker 2 relativ zueinander erhöht, während gleichzeitig die Möglichkeit erhalten bleibt, Zündspule 1 und Zündkerzenstecker 2 versetzt oder exakt axial zueinander auszurichten.Between an pulled down high voltage circuit 12 of the ignition coil and this surrounding the inside and outside and held therein by means of a press fit spark plug connector 2 is an O-ring 13 which is held in an annular groove of the spark plug connector. This increases the rigidity of the ignition coil 1 and the spark plug connector 2 relative to one another, while at the same time increasing the possibility is maintained, ignition coil 1 and spark plug connector 2 offset or aligned exactly axially to each other.

Bei der Montage des Einzelspulenzündsystems wird die komplette Einheit, bestehend aus Zündspule 1 und Zündkerzenstecker 2 in den Zylinderkopf eingeführt. Dabei gelangen die Rippen 11 in Eingriff mit der Öffnung 7 und gleiten darin entlang, bis der Zündkerzenstecker 2 mit dem Kontaktteil verrastet. Die komplette Einheit ist dann durch den Reibschluß zwischen den Rippen 11 und der Öffnung 7 und durch die Verrastung mit der Zündkerze 6 in der Wirklage gehalten. Eine gesonderte oder sogar ausschließliche Befestigung der Zündspule entfällt. Ggf. kann durch eine nicht dargestellte Abdeckhaube, die mehrere nebeneinander angeordnete Einzelspulenzündsysteme umgibt und die einen in Richtung des Pfeiles 14 verlaufenden Anschlag besitzt, eine zusätzliche axiale Fixierung des Systems erzielt werden. Es ist ohne weiteres zu erkennen, daß die dargestellte Vorrichtung einfach und sicher zu montieren ist und gleichzeitig auch unter allen auftretenden dynamischen Belastungen während des Betriebs der Brennkraftmaschine ihre Wirklage beibehältWhen assembling the single coil ignition system, the complete unit, consisting of ignition coil 1 and spark plug connector 2, is inserted into the cylinder head. The ribs 11 come into engagement with the opening 7 and slide therein until the spark plug connector 2 engages with the contact part. The complete unit is then held in the active position by the frictional engagement between the ribs 11 and the opening 7 and by the engagement with the spark plug 6. A separate or even exclusive attachment of the ignition coil is not necessary. Possibly. An additional axial fixation of the system can be achieved by a cover hood, not shown, which surrounds a plurality of individual coil ignition systems arranged next to one another and which has a stop running in the direction of the arrow 14. It can easily be seen that the device shown is simple and safe to assemble and at the same time maintains its operative position under all dynamic loads that occur during the operation of the internal combustion engine
