Parallelstartanlage mit geringem VerdrahtungsaufwandParallel start system with low wiring costs
Die Erfindung betrifft eine Parallelstartanlage zum Starten von Verbrennungsmotoren gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a parallel starting system for starting internal combustion engines according to the preamble of patent claim 1.
Zum Starten von Verbrennungsmotoren werden üblicherweise elektrisch betätigte Starter verwendet . Bei größeren Motoren mit mehreren Zehn oder Hundert Litern Hubraum, wie z . B . Schiffsmotoren, ist es bekannt, mehrere Starter parallel zu schalten, um die hohe Starterleistung bereitstellen zu können .For starting internal combustion engines usually electrically operated starters are used. For larger engines with tens or hundreds of liters, such. B. Marine engines, it is known to switch several starters in parallel to provide the high starter performance can.
Fig . 1 zeigt eine aus dem Stand der Technik bekannte Parallelstartanlage mit zwei Startern Ia, Ib . Jeder der Starter umfasst einen Startermotor 2a, 2b und ein Einrückrelais 4a, 4b, das üblicherweise zwei Aufgaben erfüllt : zum Einen spurt das Einrückrelais 4a, 4b ein vom Startermotor 2a, 2b angetriebenes Ritzel (nicht gezeigt) in einen Zahnkranz des Verbrennungsmotors ein . Zum Anderen schließt dasFig. 1 shows a parallel starting system known from the prior art with two starters Ia, Ib. Each of the starters comprises a starter motor 2a, 2b and an engagement relay 4a, 4b, which usually performs two tasks: on the one hand, the engagement relay 4a, 4b spits a pinion (not shown) driven by the starter motor 2a, 2b into a ring gear of the internal combustion engine. On the other hand that concludes
Einrückrelais 4a, 4b einen Hauptstrompfad 8 mittels eines Schließers 5a, 5b, wenn das Ritzel in den Zahnkranz eingerückt ist . Dadurch wird der eigentliche Andrehvorgang gestartet .Engagement relay 4a, 4b a main current path 8 by means of a shutter 5a, 5b, when the pinion is engaged in the sprocket. This will start the actual cranking process.
Um zu verhindern, dass einer der beiden Starter Ia, Ib früher als der andere mit dem Startvorgang beginnt, sind die beiden Starter Ia, Ib derart miteinander verschaltet, dass der Hauptstrompfad 8 zu den Startermotoren 2a, 2b erst dann geschlossen wird, wenn beide Ritzel eingerückt sind bzw . beide Einrückrelais 4a, 4b vollständig angezogen haben . Die beiden Einrückrelais 4a, 4b sind hier bezüglich ihrer Steueranschlüsse parallel geschaltet und an eine Klemme 50 angeschlossen, die mit dem Anlassschalter (Schalter 6) verbunden ist . Die Lastanschlüsse (Klemmen 30 , 30b) der Relais 4a, 4b sind hingegen seriell miteinander verschaltet . Die Klemme 30 des ersten Starters Ia ist an einer Batterie angeklemmt und wird von dieser mit einer Spannung U+ versorgt .In order to prevent one of the two starters Ia, Ib from starting earlier than the other, the two starters Ia, Ib are interconnected in such a way that the main current path 8 to the starter motors 2a, 2b is closed only when both pinions are indented or both engagement relays 4a, 4b have fully tightened. The two engagement relays 4a, 4b are here with respect to their Control terminals connected in parallel and connected to a terminal 50, which is connected to the start switch (switch 6). The load terminals (terminals 30, 30b) of the relays 4a, 4b, however, are connected in series with each other. The terminal 30 of the first starter Ia is connected to a battery and is supplied by the latter with a voltage U +.
Bei einem Startvorgang - d. h . nach Betätigen der Zündung 6 - werden die Wicklungen HW (Haltewicklung) und EW (Einzugswicklung) der Einrückrelais 4a, 4b bestromt . Dadurch ziehen beide Einrückrelais 4a, 4b an, wobei die Schalter 5a, 5b geschlossen werden . Wenn beide Schalter 5a, 5b geschlossen sind, werden beide Startermotoren 2a, 2b gleichzeitig bestromt und starten den Verbrennungsmotor . Nachteilig ist hierbei, dass beide Einrückrelais 4a, 4b den gesamten Strom für beide Startermotoren 2a, 2b schalten und führen müssen . Bei unsauberen Ansteuersignalen (Signalpreller) kann daher ein hoher Kontaktverschleiß auftreten und es besteht ein hohes Risiko für Kontaktschweißen .At a startup - d. H . after actuation of the ignition 6 - the windings HW (holding winding) and EW (pull-in winding) of the engagement relay 4a, 4b are energized. As a result, both engagement relays 4a, 4b attract, the switches 5a, 5b being closed. When both switches 5a, 5b are closed, both starter motors 2a, 2b are energized simultaneously and start the internal combustion engine. The disadvantage here is that both engagement relay 4a, 4b switch the entire power for both starter motors 2a, 2b and must lead. In the case of unclean drive signals (signal prewarters), high contact wear can therefore occur and there is a high risk of contact welding.
Es ist daher die Aufgabe der vorliegenden Erfindung, die Schaltsicherheit zu verbessern . Darüber hinaus soll eine Parallelstartanlage geschaffen werden, die mit möglichst wenig Aufwand verdrahtet werden kann . Gelöst wird diese Aufgabe gemäß der Erfindung durch die im Patentanspruch 1 angegebenen Merkmale . Weitere Ausgestaltungen der Erfindung sind Gegenstand von Unteransprüchen .It is therefore the object of the present invention to improve the switching reliability. In addition, a parallel launch system is to be created, which can be wired with the least possible effort. This object is achieved according to the invention by the features specified in claim 1. Further embodiments of the invention are the subject of dependent claims.
Ein wesentlicher Gedanke der Erfindung besteht darin, die bei herkömmlichen Einrückrelais übliche Verkettung der Funktionen „Einrücken" und „Hauptstrom schalten" aufzutrennen und statt dessen zwei Relais vorzusehen, von denen das eine (Einrückrelais ) ausschließlich die Funktion „Einrücken" und das andere (Leistungsrelais ) ausschließlich die Funktion „Hauptstrom schalten" ausführt . Das Einrückrelais und das Leistungsrelais sind vorzugsweise zusammen mit dem zugehörigen Startermotor als bauliche Einheit konstruiert . Dadurch kann eine Parallelstartanlage geschaffen werden, die einfach und kostengünstig verdrahtet werden kann und in der die Leistungsrelais nicht auf übermäßig starke Belastungen ausgelegt sein müssen .An essential idea of the invention is to separate the conventional engagement relays usual chaining the functions "engagement" and "main power switch" and instead provide two relays, one of which (engagement relay) exclusively the function "engagement" and the other (power relay ) executes exclusively the function "switch main current". The engagement relay and the power relay are preferably together with the associated starter motor constructed as a structural unit. As a result, a parallel start system can be created, which can be wired easily and inexpensively and in which the power relay must not be designed for excessive loads.
Die Starter sind vorzugsweise derart verschaltet, dass die Leistungsrelais erst dann den Hauptstrom der Startermotoren schalten, wenn alle Einrückrelais angezogen haben (d. h . alle Ritzel eingespurt sind bzw . die Einspurfedern gespannt) .The starters are preferably connected in such a way that the power relays do not switch the main current of the starter motors until all the engagement relays have been energized (ie all sprockets are meshed or the single-spider springs are tensioned).
Gemäß einer ersten Ausführungsform (Fig .2 ) der Erfindung sind die Einrückrelais zweier Starter seriell miteinander verbunden . D . h . der Steueranschluss des nachfolgenden Einrückrelais ist mit dem Lastanschluss des vorhergehenden Einrückrelais verschaltet . Die Lastanschlüsse derAccording to a first embodiment (Fig. 2) of the invention, the engagement relays of two starters are connected in series. D. H . The control connection of the following contact relay is connected to the load connection of the previous engagement relay. The load connections of the
Einrückrelais liegen vorzugsweise an Klemme 30. Bei serieller Verschaltung der Einrückrelais fließt ein relativ hoher Strom zum zweiten Einrückrelais , wodurch ein relativ dickes Anschlusskabel zwischen den Startern notwendig ist .Engagement relays are preferably on terminal 30. With serial connection of the engagement relays, a relatively high current flows to the second engagement relay, whereby a relatively thick connection cable between the starters is necessary.
Gemäß einer zweiten Ausführungsform (Fig .4 ) der Erfindung sind die Einrückrelais zweier Starter bezüglich ihrer Steueranschlüsse parallel geschaltet . Die Lastanschlüsse der Einrückrelais sind vorzugsweise seriell geschaltet, wobei der erste Lastanschluss vorzugsweise an Klemme 30 liegt . DerAccording to a second embodiment (Fig. 4) of the invention, the engagement relays of two starters are connected in parallel with respect to their control terminals. The load connections of the engagement relays are preferably connected in series, wherein the first load connection is preferably located at terminal 30. Of the
Lastanschluss des letzten Einrückrelais ist vorzugsweise mit dem Steueranschluss (50k) eines Leistungsrelais verschaltet . Die Leistungsrelais sind vorzugsweise parallel geschaltet . Die Serienschaltung der Lastanschlüsse hat den Vorteil, dass der Stromfluss zwischen zwei Startern wesentlich geringer ist .Load connection of the last engagement relay is preferably connected to the control terminal (50k) of a power relay. The power relays are preferably connected in parallel. The series connection of the load connections has the advantage that the current flow between two starters is much lower.
Gemäß einer bevorzugten Ausführungsform der Erfindung umfasst j eder der Starter ein eigenes Leistungsrelais , das den Stromfluss zum Startermotor schaltet . Wahlweise kann auch wenigstens einer der Starter kein eigenes Leistungsrelais umfassen (Fig .5) . In diesem Fall erfüllt dieses Einrückrelais beide Funktionen, nämlich „Einrücken" und „Hauptstrom schalten" .According to a preferred embodiment of the invention, each of the starters has its own power relay which switches the current flow to the starter motor. Optionally, at least one of the starters can not have their own power relay include (Fig. 5). In this case, this engagement relay fulfills both functions, namely "engage" and "switch main current".
Zwischen zwei parallel geschalteten Startern ist vorzugsweise eine dreipolige Verbindung vorgesehen . Wenn dasBetween two starters connected in parallel, a three-pole connection is preferably provided. If that
Anschlusskabel eines Starters eine Steckverbindung aufweist, können mehrere Starter in einfacher Weise verbunden werden . Bei der Verdrahtung der Starter ist dabei nur darauf zu achten, an welcher Stelle in der Kette von Startern der betreffende Starter angeordnet ist .Connecting cable of a starter has a connector, several starters can be connected in a simple manner. When wiring the starter is only to pay attention to where in the chain of starters the starter is located.

Dadurch schließen beide zugehörigen Schalter 18a, 18b etwa gleichzeitig und schließen den Strompfad 8 zwischen Klemme 30 und Klemme 45 der Startermotoren 2a bzw . 2b . Der Verbrennungsmotor (nicht gezeigt) wird dadurch etwa gleichzeitig von beiden Startermotoren 2a, 2b angetrieben .Power relay 12a, 12b energized. The power relays 12a, 12b are connected in parallel here. This closes both associated switches 18a, 18b approximately simultaneously and close the current path 8 between terminal 30 and terminal 45 of the starter motors 2a and. 2 B . The internal combustion engine (not shown) is thereby driven approximately simultaneously by both starter motors 2a, 2b.
Die beiden Starter Ia, Ib sind hier mittels einer dreipoligen elektrischen Leitung 11 miteinander verbunden . Über dieThe two starters Ia, Ib are connected to each other here by means of a three-pole electrical line 11. About the
Steuerleitung 7 zwischen Klemme 50n und 50i fließt dabei ein relativ hoher Strom von z . B . 200A, der für das Ansteuern des Relais 4b erforderlich ist . Bei der in Fig . 4 dargestellten Parallelstartanlage ist dieser Strom wesentlich reduziert, wodurch ein dünneres Kabel Verwendung finden kann .Control line 7 between terminal 50n and 50i flows in this case relatively high current of z. B. 200A required for driving the relay 4b. In the in Fig. 4 parallel launch system, this stream is substantially reduced, whereby a thinner cable can be used.
Fig . 3 zeigt den physikalischen Aufbau derFig. 3 shows the physical structure of
Parallelstartanlage von Fig . 2. Jeder der Starter Ia, Ib ist dabei als eine bauliche Einheit konstruiert, die j eweils einen Startermotor 2a, 2b, ein Startrelais 13a, 13b, ein Einrückrelais 4 und ein Leistungsrelais 12a, 12b umfasst . Die Starter Ia, Ib sind über eine dreipolige elektrische Leitung 11 miteinander verbunden .Parallel start system of FIG. 2. Each of the starters Ia, Ib is constructed as a structural unit, each comprising a starter motor 2a, 2b, a starting relay 13a, 13b, an engagement relay 4 and a power relay 12a, 12b. The starters Ia, Ib are connected to each other via a three-pole electrical line 11.
Fig . 4 zeigt eine Parallelstartanlage mit zwei Startern Ia, Ib, die im wesentlichen identisch aufgebaut sind wie die Starter von Fig . 2. Bezüglich der Erläuterung der einzelnen Elemente und deren Funktionsweise wird daher auf die Beschreibung zu Fig . 2 verwiesen . Im Unterschied zur Anordnung von Fig . 2 sind hier die Lastanschlüsse (Klemmen 50m, 50n) der Einrückrelais 4a, 4b seriell miteinander verschaltet . Dadurch fließt auf der Leitung 7 zwischen denFig. 4 shows a parallel starting system with two starters Ia, Ib, which are constructed essentially identical to the starters of FIG. 2. With regard to the explanation of the individual elements and their operation is therefore based on the description of FIG. 2 referenced. In contrast to the arrangement of FIG. 2 here are the load terminals (terminals 50m, 50n) of the engagement relay 4a, 4b connected in series with each other. As a result, flows on the line 7 between the
Klemmen 50n und 50m nur ein wesentlich geringerer Steuerstrom von ca . 2OA, wodurch eine wesentlich dünnere Leitung verwendet werden kann .Terminals 50n and 50m only a much lower control current of approx. 2OA, whereby a much thinner line can be used.
Der Lastschalter 18b des Einrückrelais 4b ist wiederum mit den Klemmen 50k der parallel geschalteten Leistungsrelais 12a, 12b verbunden . Die Steueranschlüsse (Klemme 50i) der Einrückrelais 4a, 4b sind parallel geschaltet und liegen über den Lastkontakt 14a, 14b der Startrelais j eweils an Klemme 30.The load switch 18b of the engagement relay 4b is in turn connected to the terminals 50k of the parallel-connected power relays 12a, 12b. The control terminals (terminal 50i) of the engagement relays 4a, 4b are connected in parallel and are in each case connected to terminal 30 via the load contact 14a, 14b of the starting relay.
Fig . 5 zeigt eine dritte Ausführungsform einer Parallelstartanlage mit zwei parallel geschalteten Startern Ia, Ib ähnlich Fig . 2. Bei dieser Variante umfasst j edoch nur der erste Starter Ia ein eigenes Leistungsrelais 12a . Im Unterschied zu Fig . 2 wird der Hauptstrom des Startermotors 2b vom kombinierten Einrückrelais 4b geschaltet . Das Einrückrelais 4b betätigt hierbei einen Schalter 16b, der zwischen Klemme 30 und Klemme 45 des Startermotors 2b geschaltet ist . Wenn der Kontakt 16b geschlossen wird, wird der Steueranschluss 50k des Leistungsrelais 17a bestromt . Der Kontakt 18a schaltet etwas zeitverzögert zu 16b den Strom für den Motor 2a . Diese Variante hat den Vorteil, dass nur einFig. 5 shows a third embodiment of a parallel starting system with two starters Ia, Ib connected in parallel, similar to FIG. 2. In this variant, however, only the first starter Ia has its own power relay 12a. In contrast to Fig. 2, the main current of the starter motor 2b is switched by the combined engagement relay 4b. The Engagement relay 4b in this case actuates a switch 16b, which is connected between terminal 30 and terminal 45 of the starter motor 2b. When the contact 16b is closed, the control terminal 50k of the power relay 17a is energized. The contact 18a switches the current for the motor 2a slightly delayed to 16b. This variant has the advantage that only one
Leistungsrelais 4 benötigt wird. Allerdings ergibt sich eine geringe Zeitverzögerung beim Andrehen der Motoren 2a, 2b, da das Einrückrelais 4b zunächst den Motor 2b einschaltet und danach erst das seriell verbundene Leistungsrelais 12a bestromt, das dann den Hauptstrom zum Motor 2a schaltet .Power relay 4 is required. However, there is a small time delay when starting the motors 2a, 2b, since the engagement relay 4b first turns on the motor 2b and then energized only the serially connected power relay 12a, which then switches the main current to the motor 2a.
Fig . 6a und 6b zeigen eine Parallelschaltung von drei Startern Ia, Ib und Ic . Wahlweise könnten auch mehr Starter 1 parallel geschaltet werden . Die Starter 1 sind intern alle identisch aufgebaut . Lediglich die externe Verschaltung ist j e nach Position des Starters Ia, Ib bzw . Ic in der Starterkette unterschiedlich ausgeführt . Bei einer Kette von n Startern 1 sind alle in der Mitte liegenden Starter bezüglich ihrer externen Verschaltung identisch ausgeführt . Nur der erste und letzte Starter Ia bzw . In müssen in diesem Fall unterschiedlich verdrahtet werden . Dies kann besonders einfach und kostengünstig durchgeführt werden . Fig. Figs. 6a and 6b show a parallel connection of three starters Ia, Ib and Ic. Optionally, more starters 1 could be connected in parallel. The starters 1 are all internally identical. Only the external connection is dependent on the position of the starter Ia, Ib or. Ic performed differently in the starter chain. In the case of a chain of n starters 1, all starters in the center are identical in terms of their external connection. Only the first and last starter Ia resp. In must be wired differently in this case. This can be carried out particularly easily and inexpensively.
