Abstract

Dans un dispositif de démarrage comportant deux démarreurs (11, 12) fonctionnant en parallèle, afin d'assurer l'enclenchement des moteurs d'entraînement (17, 18) chargés d'entraîner les pignons de démarrage, les enroulements de relais (21, 22) des relais d'enclenchement (19, 20) faisant avancer les pignons de démarrage ne sont commutés en parallèle qu'après engrènement desdits pignons et de telle manière qu'ils sont simultanément excités lors de l'actionnement du commutateur de démarrage (16). Après engrènement total des pignons de démarrage, des contacts de commutation (27-30) sont actionnés dans chaque démarreur (11, 12), des contacts de commutation (27, 30, 28, 29) appartenant à deux démarreurs différents (11, 12) étant commutés consécutivement et en série avec un moteur d'entraînement (17 ou 18 respectivement). L'enclenchement des moteurs d'entraînement (17, 18) est ainsi verrouillé tant que l'un des deux pignons de démarrage n'est pas engrené.In a starting device comprising two starters (11, 12) operating in parallel, in order to ensure the engagement of the drive motors (17, 18) responsible for driving the starting pinions, the relay windings (21, 22) engagement relays (19, 20) advancing the starter gears are switched in parallel only after meshing of said gears and in such a way that they are simultaneously energized when actuating the start switch (16 ). After total engagement of the starting gears, switching contacts (27-30) are actuated in each starter (11, 12), switching contacts (27, 30, 28, 29) belonging to two different starters (11, 12 ) being switched consecutively and in series with a drive motor (17 or 18 respectively). The engagement of the drive motors (17, 18) is thus locked as long as one of the two starter gears is not engaged.

Die in Fig. 1 im Schaltbild dargestellte Andrehvorrichtung für eine Brennkraftmaschine eines Kraftfahrzeugs weist zwei im Parallelbetrieb arbeitende Starter 11,12 auf. Mit 13 ist die Kraftfahrzeugbatterie, mit 14 ein Batterieschalter mit 0 15 ein Fahrtschalter und mit 16 ein Startschalter zum Anlassen der Brennkraftmaschine bezeichnet. Sind Batterieschalter 14 und Fahrtschalter 15 geschlossen, so können durch Betätigen des Startschalters 16 die beiden Starter 11,12 eingeschaltet werden, deren hier nicht 5 dargestellte Andrehritzel in den Zahnkranz einerThe starting device for an internal combustion engine of a motor vehicle shown in the circuit diagram in FIG. 1 has two starters 11, 12 working in parallel. 13 denotes the motor vehicle battery, 14 a battery switch, 0 15 a travel switch and 16 a start switch for starting the internal combustion engine. If the battery switch 14 and the travel switch 15 are closed, the two starters 11, 12 can be switched on by actuating the start switch 16

Jeder Starter 11 bzw. 12 weist neben dem Antriebsmotor 17 c bzw. 18 für den Antrieb des Andrehritzels ein Einrückrelais 19 bzw. 20 mit mindestens einer Relaiswicklung 21,22 auf. Bei Gleichstromfluß in der Relaiswicklung 21 bzw. 22 zieht das Einrückrelais 19 bzw. 20 an und schiebt das Andrehritzel in den Zahnkranz der Brennkraftmaschine ein. Ein möglicher konstruktiver Aufbau des Starters 11 bzw. 12 ist beispielsweise in der DE-OS 31 00, 869 beschrieben. Zum besseren Einspuren des Andrehritzels in den Zahnkranz der Brennkraftmaschine wird beim Vorschub des Andrehritzels gegen den Zahnkranz das Andrehritzel langsam gedreht. Dieses kann, wie in der genannten DE-OS beschrieben, mechanisch durch eine Verschraubung des Ritzels auf einer Getriebewelle bewirkt werden, aber auch - wie hier - elektrisch durch geringen Stromfluß im Antriebsmotor 17 bzw. 18, was hier über eine zweite Relaiswicklung 23 bzw. 24 des Einrückrelais 19 bzw. 20 erfolgt. Kann das Andrehritzel vollständig in den Zahnkranz der Brennkraftmaschine einspuren, so zieht das Einrückrelais 19 bzw. 20 den Relaisanker vollständig ein und schließt am Ende der Einzugsbewegung einen Schalter 25 bzw. 26, der dann den Antriebsmotor 17 bzw. 18 unmittelbar an die Kraftzeugbatterie 13 anschließt.Each starter 11 or 12 has, in addition to the drive motor 17 c or 18, an engagement relay for driving the starter pinion 19 b between 20 with at least one relay winding 21, 22. With direct current flowing in the relay winding 21 or 22, the engagement relay 19 or 20 picks up and pushes the starter pinion into the ring gear of the internal combustion engine. A possible structural design of the starter 11 or 12 is described for example in DE-OS 31 00, 869. For better engagement of the starter pinion in the ring gear of the internal combustion engine, the starter pinion is slowly rotated when the pinion gear is advanced against the ring gear. As described in the aforementioned DE-OS, this can be achieved mechanically by screwing the pinion on a gear shaft, but also - as here - electrically by means of a low current flow in the drive motor 17 or 18, which is achieved here via a second relay winding 23 or 24 of the engaging relay 19 or 20 takes place. If the starter pinion can fully mesh into the ring gear of the internal combustion engine, the engagement relay 19 or 20 pulls the relay armature in completely and closes a switch 25 or 26 at the end of the pull-in movement, which then connects the drive motor 17 or 18 directly to the motor vehicle battery 13 .
Bei einer solchen Andrehvorrichtung mit zwei parallel betriebenen Starter ist es äußerst wichtig, daß die Andrehritzel beider Starter in den Zahnkranz der Brennkraftmaschine eingespurt sind, bevor die Antriebmotoren 17,18 eingeschaltet werden, um eine Überlastung eines der Starter 11,12 zu vermeiden. Hierzu weist jeder Schalter 25,26 einen Doppelkontakt, bestehend aus den Schaltkontakten 27,28 bzw. 29,30, auf. Der Schaltkontakt 27 des Schalters 25 und der Schaltkontakt 30 des Schalters 26 sind hintereinander geschaltet und liegen in Reihe mit demIn such a starter device with two starters operated in parallel, it is extremely important that the starting pinions of both starters are engaged in the ring gear of the internal combustion engine before the drive motors 17, 18 are switched on in order to avoid overloading one of the starters 11, 12. For this purpose, each switch 25, 26 has a double contact, consisting of the switch contacts 27, 28 and 29, 30, respectively. The switch contact 27 of the switch 25 and the switch contact 30 of the switch 26 are connected in series and are in series with the
Antriebsmotor 18 des Starters 12 an der Batterie 13. In gleicher Weise sind der Schaltkontakt 29 des Schalters 26 und der Schaltkontakt 28 des Schalters 25 hintereinander geschaltet und liegen nunmehr in Reihe mit dem Antriebsmotor 17 des Starters 11 an der Batterie 13.Drive motor 18 of starter 12 on battery 13. In the same way, switch contact 29 of switch 26 and switch contact 28 of switch 25 are connected in series and are now in series with the drive motor 17 of the starter 11 on the battery 13.
Die Relaiswicklungen 21,22 der beiden Einrückrelais 19 sind parallel zueinander geschaltet und werden über den Relaiskontakt 31 eines Hilfsrelais 32 unmittelbar an die Batterie 13 angeschlossen. Die Relaiswicklung 33 desThe relay windings 21, 22 of the two engagement relays 19 are connected in parallel to one another and are connected directly to the battery 13 via the relay contact 31 of an auxiliary relay 32. The relay winding 33 of the
Hilfsrelais 32 wird bei Betätigen des Startschalters 16 mit Strom versorgt, und zwar über ein an sich bekanntes Startsperrelais 34 und Startwiederholrelais 35. Die zweiten Relaiswicklungen 23 und 24 liegen jeweils in Reihe mit der Reihenschlußwicklung 36 bzw. 37 des zugeordneten, alsAuxiliary relay 32 is supplied with power when the start switch 16 is actuated, specifically via a known start inhibitor 34 and start repeater 35. The second relay windings 23 and 24 are each in series with the series winding 36 and 37 of the associated, as

Die Wirkungsweise der beschriebenen Andrehvorrichtung ist wie folgt:The described starting device works as follows:
Wird nach Schließen des Batterieschalters 14 und desWill after closing the battery switch 14 and
Fahrtschalters 15 der Startschalter 16 betätigt, so wird über das Startsperrelais 34 und das Startwiederholrelais 35 die Relaiswicklung 33 des Hilfsrelais 32 mit der Kraftfahrzeugbatterie 13 verbunden. Dessen Relaiskontakt 31 schließt und legt die beiden parallelen RelaiswicklungenTravel switch 15 actuated the start switch 16, the relay winding 33 of the auxiliary relay 32 is connected to the motor vehicle battery 13 via the start inhibitor relay 34 and the start repeater relay 35. Its relay contact 31 closes and sets the two parallel relay windings
21,22 der Einrückrelais 19,20 an die Kraftfahrzeugbatterie 13. Bei Erregung schieben die Einrückrelais 19,20 die jeweils zugeordneten Andrehritzel in Richtung zu dem Zahnkranz der Brennkraftmaschine, wobei die Andrehritzel über die zugeordneten Antriebsmotoren 17,18 in langsame Drehung versetzt werden. Sobald das Andrehritzel des Starters 11 eingespurt ist, schließen die Schaltkontakte 27 und 28. Ist das Andrehritzel des Starters 12 noch nicht eingespurt, so geschieht nichts. Erst nach vollständigem Einspuren auch des Andrehritzels des Starters 12 kann dessen Einrückrelais 20 die beiden Schaltkontakte 29,30 des Schalters 26 schließen. In diesem Moment werden beide Antriebsmotoren 17,18 über die geschlossenen Doppelkontakte der Schalter 25,26 in Parallelschaltung an die Batterie 13 gelegt. Die Antriebsmotoren 17,18 laufen hoch und drehen über die Andrehritzel die Brennkraftmaschine an. Durch die Überkreuzschaltung der Doppelkontakte der Schalter 25,26 in den Einrückrelais 19,20 ist somit der eine Starter 11 bzw. 12 gegen den anderen Starter 12 bzw. 11 so lange verriegelt, bis beide Andrehritzel in den Zahnkranz der Brennkraftmaschine eingespurt sind. Kann eines der Andrehritzel bei einer Zahn auf Zahn-Stellung nicht einspuren, so spricht das Startwiederholrelais 35 an und wiederholt den Startvorgang wie beschrieben für beide Starter 11,12, ohne daß der Fahrtschalter 15 geöffnet und wieder geschlossen werden muß.21, 22 of the engaging relays 19, 20 to the motor vehicle battery 13. When energized, the engaging relays 19, 20 push the respectively assigned starter pinions in the direction of the ring gear of the internal combustion engine, the starter pinions being set into slow rotation via the associated drive motors 17, 18. As soon as the starter pinion 11 is engaged, the switching contacts 27 and 28 close. If the starter 12 starter pinion is not yet engaged, nothing happens. Only after complete engagement of the starter pinion 12, its engagement relay 20 can close the two switching contacts 29, 30 of the switch 26. At this moment both drive motors 17, 18 are closed via the double contacts the switch 25, 26 connected in parallel to the battery 13. The drive motors 17, 18 run up and rotate the internal combustion engine via the starting pinions. Due to the cross-connection of the double contacts of the switches 25, 26 in the engagement relay 19, 20, one starter 11 or 12 is thus locked against the other starter 12 or 11 until both pinions are engaged in the ring gear of the internal combustion engine. If one of the starter pinions cannot engage in a tooth to tooth position, the start repeater relay 35 responds and repeats the starting process as described for both starters 11, 12 without the travel switch 15 having to be opened and closed again.
Die in Fig. 2 im Schaltbild dargestellte Andrehvorrichtung gemäß einem weiteren Ausführungsbeispiel ist gegenüber der Andrehvorrichtung in Fig. 1 nur in der Art der Verriegelung der beiden Starter 11,12 gegeneinander bei mindestens einem nicht eingespurten Andrehritzel modifiziert. Die Schalter 25' bzw. 26" der Einrückrelais 19,20 sind mit nur einem einzigen Schaltkontakt 38,39 ausgerüstet, der allerdings für die doppelte Strombelastung wie die Schaltkontakte 27 - 30 in Fig. 1 ausgelegt ist. Die beiden Schaltkontakte 38,39 der Schalter 25',26' sind hintereinander geschaltet und dann in Reihe mit der Parallelschaltung der beiden Antriebsmotoren 17,18 an die Kraftzeugbatterie 13 gelegt. Auch in diesemThe starter device shown in the circuit diagram in FIG. 2 according to a further exemplary embodiment is modified compared to the starter device in FIG. 1 only in the manner of locking the two starters 11, 12 against one another with at least one starter pinion not engaged. The switches 25 'and 26 "of the engaging relays 19, 20 are equipped with only a single switch contact 38, 39, which, however, is designed for twice the current load as the switch contacts 27 - 30 in FIG. 1. The two switch contacts 38, 39 of Switches 25 ', 26' are connected in series and then connected to the motor vehicle battery 13 in series with the parallel connection of the two drive motors 17, 18
Fall kann solange, bis nicht beide Andrehritzel der beiden Starter 11,12 eingespurt sind, kein Antriebsmotor 17,18 eingeschaltet werden. Durch die Hintereinanderschaltung beider Schaltkontakte 38,39 sind beide Starter 11,12 so lange verriegelt, bis beide Andrehritzel eingespurt sind. Erst wenn nach Einspuren der Andrehritzel beide Schaltkontakte 38,39 geschlossen sind, werden die Antriebsmotore 17,18 gleichzeitig und parallel zueinander an die Kraftzeugbatterie 13 gelegt. Durch diese Modifizierung wird gegenüber der Andrehvorrichtung jeweils ein Schaltkontakt in den beiden Schaltern 25' ,26* und entsprechende Verbindungsleitungen zwischen den Schaltern 25' ,26' eingespart, jedoch müssen die Schaltkontakte 38 und 39 und die Verbindungsleitungen für die doppelteIn this case, no drive motor 17, 18 can be switched on until both starting pinions of the two starters 11, 12 are engaged. By connecting both switching contacts 38, 39 in series, both starters 11, 12 are locked until both pinions are engaged. Only when both switching contacts 38, 39 are closed after the starting pinion has been engaged, are the drive motors 17, 18 placed simultaneously and parallel to one another on the motor vehicle battery 13. By this modification compared to the starting device, one switch contact in each of the two switches 25 ', 26 * and corresponding connecting lines between the switches 25', 26 'are saved, however, the switching contacts 38 and 39 and the connecting lines for the double
Strombelastung ausgelegt werden. Im übrigen ist der Aufbau und die Wirkungsweise der Andrehvorrichtung gemäß Fig. 2 identisch mit der Andrehvorrichtung gemäß Fig. 1, so daß gleiche Bauteile mit gleichen Bezugszeichen versehen worden sind. Current load can be designed. 2 is identical to the starting device according to FIG. 1, so that the same components have been given the same reference numerals.
