Description

Beschreibung Titel  Description title
Startvorrichtung für Verbrennungsmotoren  Starting device for internal combustion engines
Die vorliegende Erfindung betrifft eine Startvorrichtung für Verbrennungsmotoren. The present invention relates to a starting device for internal combustion engines.
Startvorrichtungen für Verbrennungsmotoren umfassen im Wesentlichen einen Elektromotor, der über ein Untersetzungsgetriebe auf die Kurbelwelle des Verbrennungsmotors wirkt und diesen innerhalb von beispielsweise 0,5 bis 1 Sek. auf Drehzahlen von typisch erweise über 200 U/min beschleunigt. Die hierzu erforderliche Leistung reicht von unter 1 kW für kleine Benzinmotoren bis größer 4 kW für große Dieselmotoren. Auf Grund der hierfür kurzzeitig erforderlichen extrem hohen Ströme (Kurzschlussstrom) von einigen hundert bis zu über tausend Ampere und bedingt durch den begrenzten fixen Innenwiderstand bricht die Batteriespannung von beispielsweise 12 Volt auf bis zu 3 Volt ein, so dass die meisten elektronischen Einrichtungen im Kraftfahrzeug kurzzeitig ausfallen. Während diese Wechselwirkung des Starters mit anderen Fahrzeugkomponenten beim einmaligen Betrieb am Anfang einer Fahrt (Kaltstart) kaum von Bedeutung ist, sind die Folgen des Bordnetzspannungseinbruchs bei wiederholtem Start beim sogenannten Start-Stopp-Betrieb nicht tragbar und unter bestimmten Umständen sogar sicherheitsgefährdend. Zur Abmilderung dieser Folgen sind verschiedene Strategien bekannt, um diesen Bordnetzspannungseinbruch zu vermeiden bzw. zu unterbinden. Üblicherweise wird ein Vorwiderstand zur Begrenzung des Kurzschlussstroms eingesetzt. Starting devices for internal combustion engines essentially comprise an electric motor which acts on the crankshaft of the internal combustion engine via a reduction gear and accelerates it to speeds of typically over 200 rpm within, for example, 0.5 to 1 sec. The required power ranges from less than 1 kW for small gasoline engines to greater than 4 kW for large diesel engines. Due to the short time required for this extremely high currents (short-circuit current) of a few hundred to over a thousand amps and due to the limited fixed internal resistance breaks the battery voltage of, for example, 12 volts to up to 3 volts, so that most electronic devices in the vehicle for a short time fail. While this interaction of the starter with other vehicle components during single operation at the beginning of a journey (cold start) is of little importance, the consequences of the electrical system voltage dip during repeated start in so-called start-stop operation is not sustainable and under certain circumstances even dangerous. To mitigate these consequences, various strategies are known to avoid or prevent this on-board voltage drop. Usually, a series resistor is used to limit the short-circuit current.
Stand der Technik State of the art
Die Erfindung geht von einer Startvorrichtung für Verbrennungsmotoren aus, wie sie entsprechend der Anordnung in Figur 1 gezeigt ist. Hierbei handelt es sich um eine Startvorrichtung umfassend ein Zündschloss 1 , ein Starterrelais 2, ein Zusatzrelais 5, eine Batterie (dargestellt durch einen Pluspol), einen Starter 4 sowie einen Vorwiderstand 3 zur Begrenzung des Kurzschlussstroms durch den Starter 4. The invention is based on a starting device for internal combustion engines, as shown according to the arrangement in Figure 1. This is it to a starting device comprising an ignition lock 1, a starter relay 2, an additional relay 5, a battery (represented by a positive pole), a starter 4 and a series resistor 3 for limiting the short-circuit current through the starter. 4
Beim Betätigen des Zündschlosses 1 schließt das Starterrelais 2 den Laststromkreis, so dass in der Folge ein reduzierter Starterstrom von der Batterie durch den Vowiderstand 3 zum Starter 4 fließt. Der Vorwiderstand 3 begrenzt den Kurzschlussstrom. Upon actuation of the ignition lock 1, the starter relay 2 closes the load circuit, so that in the sequence a reduced starter current flows from the battery through the resistor 3 to the starter 4. The series resistor 3 limits the short-circuit current.
Nachdem der Starter angelaufen ist, schließt das Zusatzrelais 5, um den Vorwiderstand 3 zu überbrücken, so dass der Hauptstrom fließt. After the starter has started, the auxiliary relay 5 closes to bypass the series resistor 3, so that the main current flows.
Die Anordnung des Standes der Technik weist den Nachteil auf, dass aufgrund des Zusatzrelais und des Vorwiderstandes ein relativ großer Bauraum benötigt wird. The arrangement of the prior art has the disadvantage that due to the additional relay and the series resistor, a relatively large space is needed.
Offenbarung der Erfindung Disclosure of the invention
Erfindungsgemäß wird eine Startvorrichtung für Verbrennungsmotoren mit den Merkmalen des Patentanspruchs 1 vorgeschlagen. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche sowie der nachfolgenden Beschreibung. According to the invention, a starting device for internal combustion engines with the features of claim 1 is proposed. Advantageous embodiments are the subject of the dependent claims and the following description.
Vorteile der Erfindung Advantages of the invention
Die Erfindung beschreibt eine Startvorrichtung für Verbrennungsmotoren umfassend ein (Zusatz-) Relais mit wenigstens zwei Arbeitskontakten, wenigstens einer Kontaktplatte und wenigstens einem elektrischen Widerstandsbauteil. Das elektrische Widerstandsbauteil ist dabei so zwischen die wenigstens zwei Arbeitskontakte geschaltet, dass die Kontaktplatte in der geschlossenen Stellung des Relais das Widerstandsbauteil überbrückt. Der Vorwiderstand bildet mit dem Relais eine bauliche Einheit und liegt daher nicht als separates Bauteil mit eigenem benötigten Bauraum vor. Damit können die bisher notwendigen Verkabelungen zwischen Vorwiderstand, Starterrelais und Zusatzrelais (siehe Fig. 1 ) so- wie der Einbauplatz für den Vorwiderstand eingespart werden. In der Folge können zusätzlich zur Platzeinsparung im Motorraum Kosten minimiert werden. The invention describes a starting device for internal combustion engines comprising an (additional) relay with at least two working contacts, at least one contact plate and at least one electrical resistance component. The electrical resistance component is connected between the at least two normally open contacts such that the contact plate bridges the resistance component in the closed position of the relay. The series resistor forms a structural unit with the relay and therefore does not exist as a separate component with its own required space. Thus, the previously required wiring between series resistor, starter relay and auxiliary relay (see FIG. How to save the slot for the series resistor. As a result, in addition to space savings in the engine compartment costs can be minimized.
Eine bevorzugte Ausgestaltung sieht vor, dass sich zum Schließen des Relais die Kontaktplatte zu den zwei Arbeitskontakten hin und/oderdie zwei Arbeitskontakte zu der Kontaktplatte hin bewegen. Die Bewegung wird üblicherweise bei einem Relais von einem Elektromagnet bewerkstelligt. Die genannten Möglichkeiten für bewegbare Elemente des Relais bieten ein hohes Maß an Flexibilität. A preferred embodiment provides that, for closing the relay, the contact plate move towards the two working contacts and / or the two working contacts move towards the contact plate. The movement is usually accomplished at a relay by an electromagnet. The mentioned possibilities for movable elements of the relay offer a high degree of flexibility.
Zwei weitere Ausführungsformen zeigen Varianten zur Anordnung des elektrischen Widerstandsbauteil. Einerseits wird das elektrische Widerstandsbauteil derart in das Relais integriert, dass es zwischen den beiden Arbeitskontaktenan- gebracht ist und sich innerhalb des Relaisgehäuses befindet. Two further embodiments show variants for the arrangement of the electrical resistance component. On the one hand, the electrical resistance component is integrated in the relay in such a way that it is placed between the two working contacts and is located inside the relay housing.
Eine andere vorteilhafte Möglichkeit ist der Einbau des elektrischen Widerstandsbauteils zwischen den beiden Arbeitskontakten außerhalb des Relaisgehäuses. Mit anderen Worten verbindet das Widerstandsbauteil die außenliegenden Arbeitsanschlüsse, die mit den innenliegenden Arbeitskontakten verbunden sind oder in diese übergehen. Das Widerstandsbauteil bildet weiterhin eine bauliche Einheit mit dem Relais, welches in dieser bevorzugten Ausführungsform jedoch baulich nur gering verändert werden muss. Another advantageous possibility is the installation of the electrical resistance component between the two working contacts outside of the relay housing. In other words, the resistance component connects the external working connections, which are connected to the internal working contacts or merge into them. The resistance component further forms a structural unit with the relay, which, however, must be structurally changed only slightly in this preferred embodiment.
Das elektrische Widerstandsbauteil kann für die Anordnung an den Arbeitskontakten bzw. Arbeitsanschlüssen mit Öffnungen oder Ausnehmungen versehen sein. Mittels dieser Öffnungen kann das elektrische Widerstandsbauteil bspw. an die Arbeitskontakte bzw. Arbeitsanschlüsse angeschraubt werden. Es versteht sich, dass auch eine andere Verbindung, bspw. eine Niet- oder Schweißverbindung, möglich ist. The electrical resistance component may be provided with openings or recesses for the arrangement on the working contacts or working connections. By means of these openings, the electrical resistance component can, for example, be screwed to the working contacts or working connections. It goes without saying that another connection, for example a riveted or welded connection, is also possible.
Als Widerstandsmaterial eignet sich ein Konstantwiderstandsmaterial, wie z. B. Konstantan, Nickelin, Chrom-Nickel, Chrom-Nickel-Eisen, Chrom-Nickel- Aluminium. Weitere Vorteile und Ausgestaltungen der Erfindung ergeben sich aus der Beschreibung und der beiliegenden Zeichnung. As a resistance material is a constant resistance material, such. B. Konstantan, nickel, chromium-nickel, chromium-nickel-iron, chromium-nickel-aluminum. Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings.
Es versteht sich, dass die vorstehend genannten und die nachfolgend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen oder in Alleinstellung verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen. It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination indicated, but also in other combinations or in isolation, without departing from the scope of the present invention.
Die Erfindung ist anhand von Ausführungsbeispielen in der Zeichnung schematisch dargestellt und wird im Folgenden unter Bezugnahme auf die Zeichnung ausführlich beschrieben. The invention is illustrated schematically by means of exemplary embodiments in the drawing and will be described in detail below with reference to the drawing.
Kurze Beschreibung der Zeichnung Short description of the drawing
Figur 1 zeigt eine schematische Darstellung einer bekannten zweistufigen Anlaufbeschaltung. FIG. 1 shows a schematic representation of a known two-stage starting circuit.
Figur 2 zeigt eine schematische Darstellung einer zweistufigen Anlaufbeschaltung gemäß der Erfindung, FIG. 2 shows a schematic representation of a two-stage starting circuit according to the invention,
Figur 3 zeigt eine erste bevorzugte Ausgestaltung einer erfindungsgemäßen Startvorrichutng und Figure 3 shows a first preferred embodiment of a Startvorrichutng invention and
Figur 4 zeigt eine zweite bevorzugte Ausgestaltung einer erfindungsgemäßen Startvorrichtung. FIG. 4 shows a second preferred embodiment of a starting device according to the invention.
Ausführungsform(en) der Erfindung Embodiment (s) of the invention
Die Anlaufbeschaltung gemäß Figur 2 ist in ihren Grundelementen Zündschloss 1 , Starterrelais 2 und Starter 4 entsprechend dem Stand der Technik (Fig. 1 ) gestaltet. Der Unterschied zu Figur 1 liegt im Aufbau des hier mit 5' bezeichneten Zusatzrelais. Das Zusatzrelais 5' umfasst eine Kontaktplatte 6, zwei Arbeitskontakte 7, 8 und ein zwischen den zwei Arbeitskontakten 7, 8 geschaltetes elektrisches Widerstandsbauteil 9. Das elektrische Widerstandsbauteil 9 ist in das Zusatzrelais 5', insbesondere in das Gehäuse des Zusatzrelais 5', integriert und benötigt daher im Gegensatz zu Figur 1 keinen eigenen Bauraum. Beim Schließen des Zusatzrelais 5' verbindet die Kontaktplatte 6 die zwei Arbeitskontakte 7 und 8 und überbrückt so das elektrische Widerstandsbauteil 9. Somit weist das Zusatzrelais 5' in der geöffneten Stellung einen höheren elektrischen Widerstand mit entsprechend niedrigerem Stromfluss und in der geschlossenen Stellung einen niedrigeren e- lektrischen Widerstand mit entsprechend höherem Stromfluss auf. The starting circuit according to FIG. 2 is designed in its basic elements of the ignition lock 1, the starter relay 2 and the starter 4 according to the prior art (FIG. 1). The difference from FIG. 1 lies in the structure of the additional relay designated here by 5 '. The additional relay 5 'comprises a contact plate 6, two normally open contacts 7, 8 and a switched between the two working contacts 7, 8 electrical resistance component 9. The electrical resistance component 9 is in the additional relay 5', in particular in the housing of the additional relay 5 ', and integrated Therefore, in contrast to Figure 1 does not require its own space. When closing the auxiliary relay 5 'connects the contact plate 6, the two normally-open contacts 7 and 8, thus bridging the electrical resistance component 9. Thus, the additional relay 5' in the open position, a higher electrical resistance with a correspondingly lower current flow and in the closed position, a lower e - Lectric resistance with correspondingly higher current flow.
Die Figuren 3 und 4 beschreiben zwei bevorzugte Ausgestaltungen 20 und 30 des Zusatzrelais. Figur 3 zeigt als erstes Ausführungsbeispiel das Zusatzrelais 20, das wiederum eine Kontaktplatte 6, zwei Arbeitskontakte 7, 8 und ein elektrisches Widerstandsbauteil 9 aufweist. Die Kontaktplatte 6 ist mit einem im Zusatzrelais 20 befindlichen Elektromagnet 12 verbunden, der die Kontaktplatte 6 zum Schließen des Relais 20 auf die beiden Arbeitskontakte 7, 8 hinbewegt. Figures 3 and 4 describe two preferred embodiments 20 and 30 of the additional relay. FIG. 3 shows, as a first exemplary embodiment, the additional relay 20, which in turn has a contact plate 6, two working contacts 7, 8 and an electrical resistance component 9. The contact plate 6 is connected to an auxiliary relay 20 located in the electromagnet 12 which moves the contact plate 6 for closing the relay 20 on the two working contacts 7, 8.
Entsprechend zeigt das zweite Ausführungsbeispiel in Figur 4 die Alternative auf, nach der sich zum Schließen des Zusatzrelais 30 die beiden Arbeitskontakte 7, 8 bewegen. Hierbei zieht der Elektromagnet 12 die Arbeitskontakte 7, 8 in Richtung der Kontaktplatte 6. Die Arbeitskontakte 7, 8 sind dazu beweglich gelagert, im vorliegenden Beispiel innerhalb von Arbeitsanschlüssen 10 und 1 1 . Correspondingly, the second exemplary embodiment in FIG. 4 shows the alternative according to which the two working contacts 7, 8 move to close the additional relay 30. In this case, the electromagnet 12 pulls the normally open contacts 7, 8 in the direction of the contact plate 6. The working contacts 7, 8 are movably mounted in the present example within working connections 10 and 11.
Auch eine Kombination beider Ausführungsformen, bei der sich sowohl die Kontaktplatte als auch die Arbeitsanschlüsse aufeinander zu bewegen, ist angedacht. A combination of both embodiments, in which both the contact plate and the working ports to move towards each other, is being considered.
Sowohl die Figur 3 als auch die Figur 4 zeigen mittels einer gestrichelten Darstellung eine weitere Möglichkeit auf, das elektrische Widerstandsbauteil 9 baulich mit dem Zusatzrelais 20 bzw. 30 zu integrieren, dieses jedoch außerhalb des Relaisgehäuses anzuordnen. Hierfür wird das elektrische Widerstandsbauteil 9 zwi- sehen die Arbeitsanschlüssen 10, 1 1 außerhalb des Gehäuses geschaltet. Obwohl sich das elektrische Widerstandsbauteil nicht innerhalb des Relaisgehäuses befindet, ist es mit diesem fest verbunden und bildet eine baulichen Einheit. Beide Anordnungsalternativen des elektrischen Widerstandsbauteils 9 innerhalb und außerhalb des Relaisgehäuses zeigen damit Varianten auf, wie das elektrischeBoth FIG. 3 and FIG. 4 show, by means of a dashed representation, a further possibility of structurally integrating the electrical resistance component 9 with the additional relay 20 or 30, but arranging this outside the relay housing. For this purpose, the electrical resistance component 9 between see the working ports 10, 1 1 connected outside the housing. Although the electrical resistance component is not within the relay housing, it is firmly connected to it and forms a structural unit. Both arrangement alternatives of the electrical resistance component 9 inside and outside the relay housing thus show variants, such as the electrical
