Description
Die Erfindung betrifft einen Starter für einen Verbrennungsmotor, insbesondere für einen Verbrennungsmotor eines Kraftfahrzeugs, mit einem Gehäuse, an dem ein dem Verbrennungsmotor zuordenbarer Befestigungsflansch ausgebildet ist.The invention relates to a starter for an internal combustion engine, in particular for an internal combustion engine of a motor vehicle, with a housing, on which a mounting flange that can be assigned to the internal combustion engine is formed.
Aus dem Stand der Technik sind Starter bekannt, die einen Befestigungsflansch aufweisen, welcher einstückig mit dem Starter beziehungsweise mit einem Teil des Starters, insbesondere mit dem so genannten A-Lager, ausgebildet ist. Der Befestigungsflansch wird dabei in Abhängigkeit der Baugröße des Starters und/oder in Abhängigkeit von individuellen Kundenwünschen geformt und dimensioniert.Starters are known from the prior art, which have a mounting flange, which is formed integrally with the starter or with a part of the starter, in particular with the so-called A-bearing. The mounting flange is shaped and dimensioned depending on the size of the starter and / or depending on individual customer requirements.
Eine Ausführung des Befestigungsflansches in Stahl oder Aluminium ergibt dabei immer eine elektrischen Verbindung des Starters zum Verbrennungsmotor. Bei einigen Applikationen wird allerdings ein isolierter Aufbau des Starters gewünscht, um das Bordnetz eines Kraftfahrzeugs von dem Verbrennungsmotor getrennt zu halten. Hierfür kann der Starter beispielsweise so isoliert aufgebaut werden, dass die stromführenden Teile des Starters von dem Gehäuse elektrisch getrennt werden. Durch den im Betrieb entstehenden Abrieb der Kohlebürsten wird im Laufe der Zeit diese interne Isolation vermindert, da sich der Abrieb als Kohlenstaubfilm im Inneren des Gehäuses absetzt, und so eine galvanische Verbindung mit dem Startergehäuse und damit mit dem Verbrennungsmotor entstehen kann. Aus der
Erfindungsgemäß ist dem Befestigungsflansch mindestens ein elektrisch isolierendes Isolierteil zugeordnet, sodass keine elektrische Verbindung zwischen dem Starter und dem Verbrennungsmotor beziehungsweise einem Startergehäuse und einem Verbrennungsmotorgehäuse besteht. Dadurch kann auf eine aufwendige interne Isolation des Starters verzichtet und eine dauerhafte elektrische Isolierung zwischen dem Starter und dem Verbrennungsmotor gewährleistet werden.According to the invention, the fastening flange is assigned at least one electrically insulating insulating part, so that there is no electrical connection between the starter and the internal combustion engine or a starter housing and an internal combustion engine housing. This eliminates the need for a complex internal insulation of the starter and a permanent electrical insulation between the starter and the engine can be ensured.
Zweckmäßigerweise besteht das Isolierteil zumindest teilweise aus einem elektrisch isolierenden Material, um den Starter elektrisch von dem Verbrennungsmotor zu trennen. Bevorzugt ist der Starter allein über das Isolierteil mit dem Verbrennungsmotor verbunden. Das bedeutet, dass zwischen dem Verbrennungsmotor und dem Starter kein direkter Kontakt besteht, und so eine sichere elektrische Abkopplung des Verbrennungsmotors von dem Starter realisiert ist, sodass der Verbrennungsmotor keinen elektrischen Kontakt über den Starter zum Bordnetz des Kraftfahrzeugs hat.Conveniently, the insulating member is at least partially made of an electrically insulating material to electrically disconnect the starter from the engine. Preferably, the starter is connected solely to the internal combustion engine via the insulating part. This means that there is no direct contact between the internal combustion engine and the starter, and so a reliable electrical decoupling of the internal combustion engine is realized by the starter, so that the internal combustion engine has no electrical contact via the starter to the electrical system of the motor vehicle.
Nach einer Weiterbildung der Erfindung weist das Isolierteil mindestens einen Bereich auf, der aus dem elektrisch isolierenden Material besteht und über den gesamten Querschnitt oder einen Teilbereich des Querschnitts ausgebildet ist. Es folgt also beispielsweise in Verbindungsrichtung im Isolierteil ein elektrisch leitender Bereich auf einen elektrisch isolierenden Bereich. Durch die Ausbildung des isolierenden Bereichs über den gesamten Querschnitt des Isolierteils ist eine vollständige elektrische Entkopplung der zwei durch das Isolierteil verbundenen Baueinheiten möglich.According to a development of the invention, the insulating part has at least one region, which consists of the electrically insulating material and is formed over the entire cross section or a partial region of the cross section. Thus, for example, in the connection direction in the insulating part, an electrically conductive region follows an electrically insulating region. By forming the insulating region over the entire cross section of the insulating part, a complete electrical decoupling of the two units connected by the insulating part is possible.
Zweckmäßigerweise ragt der Teilbereich, der aus dem elektrisch isolierenden Material besteht, aus einer, dem Verbrennungsmotor und/oder dem Starter zugeordneten Stirnfläche des Isolierteils heraus, sodass ein elektrisch leitender Bereich des Isolierteils, nicht direkt mit dem Verbrennungsmotor und/oder mit dem Starter in Berührung kommt.Expediently, the partial region which consists of the electrically insulating material protrudes from an end face of the insulating part associated with the internal combustion engine and / or the starter, so that an electrically conductive region of the insulating part does not come into direct contact with the internal combustion engine and / or with the starter comes.
Vorteilhafterweise ist an dem Isolierteil mindestens ein elektrisch isolierendes Isolierelement angeordnet, wobei das Isolierelement an einer der Stirnseiten des Isolierteils beispielsweise durch Kleben befestigt ist. Dies bietet eine noch günstigere, leichter herstellbare Möglichkeit einen elektrischen Kontakt zwischen Starter und Verbrennungsmotor zu unterbinden. Das Isolierteil kann so beispielsweise grundsätzlich aus einem elektrisch leitfähigen Material bestehen und allein durch daran angeordnete Isolierelemente seine isolierende Wirkung erhalten. Das Isolierelement ist dazu vorteilhafterweise als Isolierplättchen oder Isolierring ausgebildet. Vorteilhafterweise sind mehrere Isolierplättchen über den Umfang des Isolierteils verteilt an zumindest einer Stirnseite angebracht. Natürlich muss auch auf eine Isolierung von Befestigungselementen, wie beispielsweise Schrauben geachtet werden, wobei vorteilhafterweise elektrisch nicht leitende Befestigungselemente verwendet werden und/oder die mit den Befestigungselementen in Kontakt stehenden Kontaktbereiche des Isolierteils und/oder des Befestigungsflanschs aus dem isolierenden Material bestehen, oder entsprechend geformte, zugeordnete Isolierelemente aufweisen. Der Isolierring kann dazu als Unterlegscheibe für Muttern oder Schraubenköpfe, die zur Befestigung des Isolierteils dienen, vorgesehen sein.Advantageously, at least one electrically insulating insulating element is arranged on the insulating part, wherein the insulating element is attached to one of the end sides of the insulating part, for example by gluing. This provides an even cheaper, easier to produce way to prevent electrical contact between the starter and internal combustion engine. The insulating part may thus for example basically consist of an electrically conductive material and obtain its insulating effect solely by insulating elements arranged thereon. The insulating element is advantageously designed as a Isolierplättchen or insulating ring. Advantageously, a plurality of insulating plates are distributed over the circumference of the insulating part mounted on at least one end face. Of course, care must also be taken to insulate fasteners, such as screws, advantageously using electrically non-conductive fasteners and / or the contact areas of the insulator and / or mounting flange made of the insulative material in contact with the fasteners, or correspondingly shaped , have associated insulating elements. The insulating ring can be provided as a washer for nuts or screw heads, which serve to secure the insulating part.
Bevorzugt ist das Isolierteil im Bereich einer Schraubenöffnung und/oder an der Innenseite der Öffnungen aus dem isolierenden Material gefertigt, sodass eine partielle Isolierung hergestellt werden kann, ohne dass auf die mechanischen Festigkeitswerte des ursprünglich verwendeten Materials für den Halteflansch verzichtet werden muss. Alternativ dazu ist vorteilhafterweise eine entsprechend geformte Hülse, die aus dem isolierenden Material besteht, in der Öffnung angeordnet.Preferably, the insulating part in the region of a screw opening and / or on the inside of the openings made of the insulating material, so that a partial insulation can be produced without having to do without the mechanical strength values of the originally used material for the retaining flange. Alternatively, an equivalent is advantageously molded sleeve, which consists of the insulating material disposed in the opening.
Vorteilhafterweise ist das gesamte Isolierteil aus dem isolierenden Material gefertigt, sodass dieses möglichst einfach und kostengünstig hergestellt werden kann und eine sichere Isolierung zwischen dem Starter und dem Verbrennungsmotor gewährleistet ist.Advantageously, the entire insulating part is made of the insulating material, so that it can be made as simple and inexpensive as possible and secure isolation between the starter and the internal combustion engine is ensured.
Das Isolierteil ist bevorzugt als ein dem Verbrennungsmotor zuordenbarer Halteflansch ausgebildet. So kann der Starter über das Isolierteil beziehungsweise den Halteflansch an dem Verbrennungsmotor befestigt werden.The insulating part is preferably designed as a holding flange that can be assigned to the internal combustion engine. Thus, the starter can be attached to the internal combustion engine via the insulating part or the retaining flange.
Vorteilhafterweise ist der Halteflansch als ein am Starter und/oder am Verbrennungsmotor in mindestens zwei Positionen verdreht anordenbarer Drehflansch ausgebildet. Dies hat den Vorteil, dass die konkrete Einbaulage des Starters an einem Verbrennungsmotor und in einem dabei zur Verfügung stehenden Bauraum, wie beispielsweise in dem Motorraum eines Kraftfahrzeugs, im Vorfeld nicht aufwendig geklärt und entsprechend umgesetzt werden muss. Zweckmäßigerweise weist der Halteflansch eine im Wesentlichen kreisrunde Ringform auf. Dies bietet die einfache Möglichkeit, auf engem Raum eine Verdrehung des Starters um seine axiale Orientierung zu realisieren. Dabei ist der Halteflansch und/oder der Befestigungsflansch des Starters vorteilhafterweise so ausgebildet, dass der Starter schrittweise um die Drehachse der Antriebswelle verdreht und in mehreren, bestimmten Positionen befestigt werden kann. Dadurch wird die Entwicklung eines passenden Befestigungsflansches für einen Verbrennungsmotor erleichtert, da durch eine zweiteilige Lösung in Form des Starters mit einem daran angeordneten verdrehbaren, separaten Halteflansch, beziehungsweise Isolierteil, welcher einen Freiheitsgrad bezüglich der Ausrichtung des Starters an dem Verbrennungsmotor ermöglicht, die Anbauposition des Starters in gewissen Grenzen an die örtlichen Gegebenheiten, also an den Bauraum, angepasst werden kann. Vorteilhafterweise ist mindestens eine Öffnung beziehungsweise Schraubenöffnung loch- oder langlochförmig ausgebildet. Durch die Anordnung mehrerer lochförmiger, also kreisförmiger, Schraubenöffnungen beziehungsweise Bohrungen in dem Halteflansch ist eine schrittweise Verdrehung des Starters und/oder des Verbrennungsmotors möglich. Mittels einer Langlochausführung ist ein stufenloses Verdrehen des Starters um seine axiale Orientierung auf einfache Art und Weise realisiert. Dabei korrespondieren die jeweiligen Schraubenöffnungen natürlich mit entsprechenden Durchführungs- und/oder Gewindeöffnungen an dem Befestigungsflansch und/oder dem Gehäuse des Verbrennungsmotors. Das Isolierelement kann auch vorteilhafterweise als Isolier-Zwischenring ausgebildet sein, dessen Achse deckungsgleich mit der Achse des als Halteflansch ausgebildeten, kreisringförmigen Isolierteils ist. Die Schraubenöffnungen, loch- oder langlochförmig, können wie oben beschrieben elektrisch isoliert werden.Advantageously, the retaining flange is designed as a rotary flange which can be arranged twisted in at least two positions on the starter and / or on the internal combustion engine. This has the advantage that the specific installation position of the starter on an internal combustion engine and in a space available, such as in the engine compartment of a motor vehicle, does not need to be clarified in advance and implemented accordingly. Conveniently, the retaining flange has a substantially circular ring shape. This offers the simple possibility to realize in a small space a rotation of the starter about its axial orientation. In this case, the retaining flange and / or the mounting flange of the starter is advantageously designed so that the starter can be rotated stepwise about the axis of rotation of the drive shaft and secured in several specific positions. This facilitates the development of a suitable mounting flange for an internal combustion engine, since the mounting position of the starter can be achieved by a two-part solution in the form of the starter with a rotatable, separate holding flange or insulating part which allows a degree of freedom with respect to the orientation of the starter on the internal combustion engine within certain limits to the local conditions, so the space can be adjusted. Advantageously, at least one opening or screw opening is hole or slot-shaped educated. The arrangement of a plurality of hole-shaped, so circular, screw holes or holes in the retaining flange a stepwise rotation of the starter and / or the internal combustion engine is possible. By means of a slot design, a continuous rotation of the starter about its axial orientation is realized in a simple manner. In this case, the respective screw openings of course correspond with corresponding passage and / or threaded openings on the mounting flange and / or the housing of the internal combustion engine. The insulating element may also be advantageously formed as an insulating intermediate ring whose axis is congruent with the axis of the formed as a retaining flange, annular insulating part. The screw holes, hole or slot-like, can be electrically isolated as described above.
Zweckmäßigerweise ist als isolierendes Material Keramik, Kunststoff und/oder ein isolierender Verbundwerkstoff vorgesehen.Conveniently, ceramic, plastic and / or an insulating composite material is provided as the insulating material.
Ferner betrifft die Erfindung einen Verbrennungsmotor, insbesondere für ein Kraftfahrzeug, mit einem Starter wie er oben beschrieben wurde. Der Vorteil liegt darin, dass eine elektrische Isolation von dem Verbrennungsmotor zu dem Starter dauerhaft durch das Isolierteil gewährleistet ist.Furthermore, the invention relates to an internal combustion engine, in particular for a motor vehicle, with a starter as described above. The advantage is that an electrical insulation from the engine to the starter is permanently ensured by the insulating part.
Darüber hinaus betrifft die Erfindung einen Halteflansch für eine elektrische Maschine, insbesondere für einen Starter eines Kraftfahrzeugs, wobei der Halteflansch als Isolierteil ausgebildet ist und zumindest teilweise aus einem elektrisch isolierenden Material besteht und/oder mindestens ein an dem Halteflansch angeordnetes elektrisch isolierendes Isolierelement aufweist, sodass eine Baueinheit, wie beispielsweise ein Verbrennungsmotor, an dem die elektrische Maschine mittels des Halteflansches befestigt werden soll, elektrisch von der elektrischen Maschine entkoppelt ist.Moreover, the invention relates to a retaining flange for an electrical machine, in particular for a starter of a motor vehicle, wherein the retaining flange is formed as an insulating part and at least partially made of an electrically insulating material and / or has at least one arranged on the retaining flange electrically insulating insulating member, so a structural unit, such as an internal combustion engine, to which the electric machine is to be fastened by means of the retaining flange, is electrically decoupled from the electrical machine.
Vorteilhafterweise ist der Halteflansch als ein in mindestens zwei Positionen verdreht anordenbarer Drehflansch ausgebildet.Advantageously, the retaining flange is designed as a rotatable in at least two positions arranged rotary flange.

In der Anlagefläche 5 sind mehrere über den Umfang verteilt angeordnete Schraubenöffnungen 11 auf einem Radius um die Drehachse 6 angeordnet, wobei nicht alle sich wiederholende Elemente, wie zum Beispiel die Schraubenöffnung 11, in den Figuren mit Bezugszeichen versehen sind. Das als Halteflansch beziehungsweise Flanschring ausgeführte Isolierteil 2 weist auf einem Radius Schraubenöffnungen 12 auf, die im zusammengebauten Zustand mit den Schraubenöffnungen 11 korrespondieren, wobei das Isolierteil 2 so um die Drehachse 6 gedreht werden kann, dass die am Isolierteil 2 ausgebildeten Schraubenöffnungen 12 wahlweise mit unterschiedlichen Schraubenöffnungen 11 des Starters 1 korrespondieren, sodass das Isolierteil 2 in unterschiedlichen Positionen an dem Befestigungsflansch 4 des Starters 1 beziehungsweise des A-Lagers 3 befestigt werden kann. Dazu sind die Schraubenöffnungen 11 und die Befestigungsöffnungen 12 vorteilhafterweise axial parallel zu der Drehachse 6 ausgerichtet. Das Isolierteil 2 wird dabei mit seiner Ringöffnung 10 auf die Schulter 9 geschoben, bis seine Rückseite 13 auf der Anlagefläche 5 aufliegt.In the contact surface 5 a plurality of circumferentially distributed
Das Isolierteil 2 beziehungsweise der Halteflansch weist drei um 120° zueinander versetzte Befestigungsöffnungen 14 auf, die auf einem Radius liegen, der größer ist als der der Schraubenöffnungen 11 beziehungsweise 12. Der Befestigungsflansch 4 weist an seinem Umgang 15 Aussparungen 16 auf, die so geformt und angeordnet sind, dass durch die Befestigungsöffnungen 14 geführte Schrauben, die beispielsweise zum Befestigen des Isolierteils 2 an dem Verbrennungsmotor dienen, an dem Befestigungsflansch 4 vorbeigeführt werden können. Vorteilhafterweise sind die Aussparungen 16 so geformt, dass die Schraubenköpfe der durchgeführten Schrauben in den Aussparungen 16 liegen. Dabei sind die Aussparungen 16 ebenfalls so angeordnet, dass der Halteflansch 2 in mehreren Positionen an dem Befestigungsflansch 4 befestigt werden kann.The insulating
Unter Umständen ist es vom Kunden gewünscht, dass zwischen dem Starter 1 und einem Verbrennungsmotor, an dem der Starter 1 befestigt ist, kein elektrischer Kontakt besteht. Dazu wird der Starter häufig isoliert aufgebaut, sodass keine elektrischen Ströme beziehungsweise Spannungen über sein Gehäuse geleitet werden. Im Laufe der Zeit jedoch wird jedoch durch den Abrieb der im Starter befindlichen Kohlebürsten die interne Isolation vermindert, weil Kohlestaub sich als dünner Film auf den in dem Gehäuse befindlichen Komponenten des Starters und der Innenseite des Gehäuses niederlegt, und so eine galvanische Verbindung herstellt.It may be desired by the customer that there is no electrical contact between the
Um eine dauerhafte elektrische Isolation des Verbrennungsmotors zu dem Starter 1 zu gewährleisten, ist das Isolierteil 2 zumindest teilweise aus einem elektrisch isolierenden Material gefertigt. Dabei kann das Isolierteil 2 vorteilhafterweise einen oder mehrere Bereiche aus elektrisch isolierendem Material aufweisen, die senkrecht zu der Drehachse 6 angeordnet sind, sodass kein elektrischer Kontakt von dem Starter 1 über das Isolierteil 2 zu einem der Stirnfläche 17 des Isolierteils 2 zugeordneten Verbrennungsmotor entsteht. Alternativ oder zusätzlich können die Bereiche um die Schraubenöffnungen 12 und/oder die Befestigungsöffnungen 14 aus dem elektrisch isolierenden Material gefertigt sein, sodass zumindest eine partielle Isolation gewährleistet wird und die Festigkeitswerte des ursprünglich verwendeten Materials weiterhin Verwendung finden.
