Description

Die Erfindung betrifft ein Elektromotorisches Stellglied mit einem Gehäuse und einem auf einer Antriebsseite innerhalb des Gehäuses angeordneten Elektromotors für den Antrieb eines in dem Gehäuse angeordneten beweglichen Elementes, insbesondere einer Drosselklappe, wobei an dem Gehäuse ein separates Elektronikgehäuse zur Aufnahme einer Steuer- und/oder Auswerteelektronik befestigbar ist und die Antriebsseite über elektrische Verbindungsmittel mit dem Elektronikgehäuse verbunden istThe invention relates to an electromotive actuator with a housing and an electric motor disposed on a drive side within the housing for driving a arranged in the housing movable Elementes, in particular a throttle valve, wherein on the housing a separate Electronics housing for receiving a control and / or evaluation is fastened and the drive side via electrical connection means connected to the electronics housing

Aus der Firmenschrift "VDO Motormanagement" (T 51/91) ist ein elektromotorisches Stellglied bekannt, das dort unter dem Namen "VDO E-Gas III" gezeigt ist.The company publication "VDO engine management" (T 51/91) is an electromotive Actuator known that there under the name "VDO E-gas III" shown is.

Dieses elektromotorische Stellglied weist ein Gehäuse auf, wobei in dem Gehäuse eine Drosselklappenwelle, die eine Drosselklappe trägt, drehbar gelagert ist. Die Drosselklappenwelle wird von einem Stellantrieb angetrieben, der auf einer Antriebsseite innerhalb des Gehäuses angeordnet ist.This electromotive actuator has a housing, wherein in the housing a throttle shaft carrying a throttle rotatably mounted is. The throttle shaft is driven by an actuator, the on a drive side is disposed within the housing.

Dieses elektromotorische Stellglied mit einer Drosselklappe dient der Leistungssteuerung von Fremdkraftmaschinen, von Fahrzeugen, wobei in dieser Firmenschrift ein System gezeigt ist, bei dem die Drosselklappe sowohl über den Stellantrieb als auch über ein mechanisches Gestengel (Bowdenzug) durch die Betätigung eines Gaspedales verstellt werden kann.This electromotive actuator with a throttle serves the power control of foreign machinery, of vehicles, being in this Company publication is shown a system in which the throttle both over the actuator as well as a mechanical gesture gel (Bowden cable) can be adjusted by the operation of an accelerator pedal.

Ein elektronisches Steuergerät zur Steuerung des Stellantriebes ist über ein Verbindungskabel mit dem elektromotorischen Stellglied verbunden, wobei das elektronische Steuergerät in einem Fahrzeug in einer größeren Entfernung zu dem elektromotorischen Stellglied, das im Motorraum angeordnet ist, untergebracht ist. So ist in der Regel das elektronische Steuergerät in Fahrtrichtung betrachtet hinter einer Spritzwand oder auch zum Beispiel im Bereich des Handschuhfaches des Fahrzeuges angeordnet. Daraus ergibt sich ein hoher Montageaufwand bei der Installation des E-Gas-Systemes, wobei noch dazu kommt, daß aufgrund der langen Verbindung zwischen dem elektronischen Steuergerät und dem elektromotorischen Stellglied die Ansteuersignale für den Stellantrieb aufgrund elektromagnetischer Einstrahlungen verfälscht werden können, so daß es zu einer fehlerhaften und gegebenenfalls gefährlichen Leistungseintellung kommen kann.An electronic control unit for controlling the actuator is via a Connecting cable connected to the electromotive actuator, wherein the electronic control unit in a vehicle at a greater distance too the electromotive actuator, which is arranged in the engine compartment housed is. So is usually the electronic control unit in the direction of travel considered behind a bulkhead or even in the area of Glove compartment of the vehicle arranged. This results in a high Assembly effort in the installation of the e-gas system, in addition to comes that because of the long connection between the electronic Control unit and the electromotive actuator, the drive signals for the Actuator be corrupted due to electromagnetic radiation can, making it a flawed and possibly dangerous Performance can come.

Die Herstellung des Gehäuses des elektromotorischen Stellgliedes mit Drosselklappe hingegen hat sich in den letzten Jahren bewährt, so daß ein solches Gehäuse beispielsweise aus Aluminiumdruckguß rationell gefertigt werden kann.The manufacture of the housing of the electromotive actuator with throttle On the other hand, it has proven itself in recent years, so that such Housing be made for example of die-cast aluminum efficiently can.

Neben dem in der Firmenschrift gezeigten E-Gas-System sind auch solche Systeme bekannt, die unter den Begriff "Drive-by-wire" fallen, worunter zu verstehen ist, daß die Betätigung des Gaspedales in ein elektrischen Signal umgesetzt wird, wobei dieses elektrische Signal dem elektronischen Steuergerät zugeführt wird, und das elektronische Steuergerät den Stellantrieb in dem elektromotorischen Stellglied in Abhängigkeit der erfaßten Gaspedalbetätigung ansteuert. Auch hier ist wieder die gleiche, schon eingangs beschriebene Problematik gegeben, daß nämlich das elektronische Steuergerät weit entfernt ist von dem elektromotorischen Stellglied und es so zu Fehlansteuerungen des Stellantriebes kommen kann; sollen diese Fehlansteuerungen durch elektomagnetische Einstrahlungen von außen vermieden werden, ist eine aufwendige Abschirmung der Verbindung zwischen dem elektronischen Steuergerät und dem elektromotorischen Stellglied erforderlich, was ebenfalls aufgrund des hohen Aufwandes für die Abschirmung von Nachteil ist.In addition to the e-gas system shown in the company brochure are also such Systems are known, which fall under the term "drive-by-wire", to understand by what is that the operation of the accelerator pedal converted into an electrical signal is, this electrical signal to the electronic control unit is supplied, and the electronic control unit, the actuator in the electromotive Actuator in response to the detected accelerator pedal actuation controls. Again, the same, already described at the beginning problem given that the electronic control unit is far away from the electromotive actuator and so it to Fehlansteuerungen the actuator can come; should this faulty control by electromagnetic Radiations from the outside are avoided, is a complex shielding the connection between the electronic control unit and the Electromotive actuator required, which is also due to the high Effort for the shield is disadvantageous.

Aus der EP-A-0 844 378 ist ein elektromotorisches Stellglied mit einem Gehäuse und einem auf einer Antriebsseite innerhalb des Gehäuses angeordneten Elektromotor für den Antrieb einer in dem Gehäuse angeordneten Drosselklappe bekannt. An dem Gehäuse ist ein separates Elektronikgehäuse mit einer Steuer- und/oder Auswerteelektronik befestigt. Die Antriebsseite ist über durch das Gehäuse geführte Leitungsdrähte mit dem Elektronikgehäuse verbunden.From EP-A-0 844 378 is an electromotive actuator with a housing and one disposed on a drive side within the housing Electric motor for driving a throttle valve disposed in the housing known. On the housing is a separate electronics housing with a Control and / or evaluation mounted. The drive side is over the housing guided wires connected to the electronics housing.

Der Erfindung liegt die Aufgabe zugrunde, ein elektromotorisches Stellglied dahingehend zu verbessern, daß Fehlansteuerungen des Stellantriebes mit einfachen Mittel vermieden werden, auch schon an sich bekannte, in Serie gefertigte Gehäuse des elektromotorischen Stellgliedes weiter verwendet können und eine Serienfertigung mit rationeller Montage ermöglicht wird.The invention is based on the object, an electromotive actuator to the effect to improve that Fehlansteuerungen the actuator with simple Means are avoided, already known per se, mass-produced Housing of the electromotive actuator can continue to be used and a series production with rational assembly is made possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die elektrischen Verbindungsmittel Bestandteil des Elektronikgehäuses sind und das Drosselklappengehäuse einen Stecker oder eine Buchse aufweist, wobei an dem dem Stecker oder der Buchse zugewandtem Ende der Verbindungsmittel eine auf dem Stecker oder die Buchse abgestimmte Kupplung vorgesehen ist.This object is achieved in that the electrical Connecting means are part of the electronics housing and the throttle body having a plug or a socket, wherein on the Plug or the socket facing the end of the connecting means on the connector or the socket tuned coupling is provided.

Durch die räumliche Nähe des Steuergerätes (Steuer- und/oder Auswerteelektronik) zumindest zu dem Stellantrieb kann die elektrische Verbindung zwischen diesen Teilen kurz gehalten werden, so daß der Weg, auf dem elektomagnetische Einstrahlungen stattfinden können, drastisch reduziert ist. Daurch können elektromagnetische Einstrahlungen das Ausgangssignal eines Sensors, der die Stellung des beweglichen Elementes erfaßt, wobei das Ausgangssignal dem elektronischen Steuergerät zugeführt wird, nicht verfälschen, so daß durch die enge räumliche Nachbarschaft des elektronischen Steuergerätes zu dem Stellantrieb fehlerhafte Ansteuerungen des beweglichen Elementes aufgrund fehlerhafter Stellungssignale, die den Regelprozeß verfälschen, vermieden werden.Due to the spatial proximity of the control unit (control and / or evaluation electronics) at least to the actuator, the electrical connection be kept short between these parts, so that the way on which electromagnetic Radiations can take place, is drastically reduced. As a result, electromagnetic radiation can cause the output signal of a Sensor which detects the position of the movable element, wherein the output signal supplied to the electronic control unit, do not distort it, so that by the close spatial proximity of the electronic control unit to the actuator erroneous controls of the movable element due to erroneous position signals that distort the control process, be avoided.

Außerdem ist der Vorteil gegeben, daß ein an sich bekanntes (insbesondere das elektromotorische Stellglied, daß aus der Firmenschrift bekannt ist) und sich schon in Serienproduktion befindes Gehäuse nicht abgeändert werden muß, da das Elektronikgehäuse selber an dem Gehäuse des elektromotorischen Stellgliedes befestigt wird. Darüber hinaus wird die Änderung der Formen, mit denen das Gehäuse zum Beispiel im Druckguß hergestellt wird, vermieden, so daß eine teure und aufwendige Änderung der Formen für das Druckgussgehäuse entfallen kann. Dies ist gerade unter wirtschaftlichen Aspekten, insbesondere bei einer Serienproduktion, von großer Bedeutung.In addition, there is the advantage that a known per se (in particular the electromotive actuator, which is known from the company publication) and already in mass production befindes housing are not changed must, since the electronics housing itself to the housing of the electromotive Actuator is attached. In addition, the change of shapes, with which the housing is produced for example by die casting, avoided so that an expensive and elaborate change of forms for the Die-cast housing can be omitted. This is just under economic Aspects, especially in series production, are of great importance.

In vorteihafter Weise wird das Elektronikgehäuse an das Gehäuse angeklebt, so daß schnell und einfach eine komplette Einheit sowohl mit der Mechanik (Antrieb) als auch der Elektronik (Steuergerät) in kompakter Bauweise zur Verfügung steht. Darüber hinaus entfällt der lästige Verkabelungsaufwand, der erforderlich wäre, wenn das Steuergerät in Entfernung zu dem Stellglied angebracht wäre.In vorteihafter way, the electronics housing is adhered to the housing, so that quickly and easily a complete unit with both the mechanics (Drive) and the electronics (control unit) in a compact design for Available. In addition, eliminates the annoying cabling, the would be required if the controller mounted in distance to the actuator would.

Dadurch daß die Antriebsseite des elektromotorischen Stellgliedes über elektrische Verbindungsmittel mit dem Elektronikgehäuse verbunden ist und die elektrischen Verbindungsmittel Bestandteil des Elektronikgehäuses sind, wird der Vorteil erreicht, daß das Elektronikgehäuse mit den Verbindungsmitteln in einem Durchgang herstellbar ist, wobei nur noch das Steuergerät (insbesondere die Steuer- und/oder die Auswerteelektronik) in das Elektronikgehäuse eingesetzt werden muß, wobei dann anschließend diese Einheit an dem Gehäuse des elektromotorischen Stellgliedes befestigt werden muß. Dies macht sich bei der Serienfertigung aufgrund einer rationellen Montage positiv bemerkbar. Characterized in that the drive side of the electromotive actuator via electrical Connecting means is connected to the electronics housing and the electrical Connecting means are part of the electronics housing, the Advantage achieved that the electronics housing with the connecting means in one Continuity can be produced, with only the control unit (in particular the control and / or the evaluation) in the Electronics housing must be used, in which case then this Unit be attached to the housing of the electromotive actuator got to. This makes itself in the series production due to a rational assembly positively noticeable.

In Weiterbildung der Erfindung ist das Gehäuse ein Drosselklappengehäuse zur Aufnahme einer von dem Elektromotor antreibbaren Drosselklappe, wobei diese Anwendung daher von besonderem Vorteil ist, da innerhalb des Motorraumes von Fahrzeugen nur wenig Bauraum zur Verfügung steht, der nunmehr durch die räumlich benachbarte Anordnung auch des Elektronikgehäuses mit dem Steuergerät optimal ausgenutzt wird. Auch hier ist es wieder von besonderer Bedeutung, daß die Verbindung zwischen dem Steuergerät und dem Stellglied kurz gehalten wird, da gerade bei Ottomotoren, die die Fahrzeuge antreiben, die Zündung mit deren Hochspannungsimpulsen zu Störeinstrahlungen führen kann. Daher ist die unmittelbare Anordnung des Elektronigehäuses zu dem Stellglied von Vorteil, da mit der erfindungsgemäßen Ausgestaltung die Verbindung einer Erfassungseinrichtung für die Position der Drosselklappe und gegebenenfalls weiterer Erfassungseinrichtungen besonders kurz gehalten werden kann.In development of the invention, the housing is a throttle body for receiving a drivable by the electric motor throttle, wherein This application is therefore of particular advantage, since within the engine compartment Of vehicles only little space is available, the now by the spatially adjacent arrangement and the electronics housing with the control unit is optimally utilized. Again, it is special Meaning that the connection between the controller and the actuator is kept short, especially with gasoline engines that power the vehicles, the ignition with their high voltage pulses to interference can lead. Therefore, the immediate arrangement of the electron housing is too the actuator advantageous because with the embodiment of the invention the Connection of a detection device for the position of the throttle valve and optionally further detection devices kept particularly short can be.

Durch die auf den Stecker abgestimmte Kupplung wird auf schnelle Art und Weise die elektrische Verbindung zwischen der Elektronikseite und der Antriebseite hergestelt. Bei einem Stecker auf der Antriebsseite ist die Kupplung beispielsweise als dem Stecker entsprechende Buchse ausgestaltet, wobei bei der Kupplung noch Mittel zum Abdichten dieser Kupplungsverbindung vorgesehen sind. Darüber hinaus ist die Kupplung der elektrischen Verbindungsmittel und/oder das entsprechende Gegenstück auf der Antriebsseite so konstruktiv aufeinander abgestellt, daß ein leichtes und verwechslungsfreies Einführen gegeben ist.By the tuned to the connector coupling is in a quick way and Make the electrical connection between the electronics side and the drive side hergestelt. For a plug on the drive side is the coupling designed, for example, as the plug corresponding socket, wherein at the coupling still provided means for sealing this coupling connection are. In addition, the coupling of the electrical connection means and / or the corresponding counterpart on the drive side so constructive put on each other that a light and unmistakable insertion given is.

In Weiterbildung der Erfindung weisen das Gehäuse und/oder das Elektronikgehäuse Befestigungsmittel zur gegenseitigen Befestigung aneinander auf. Solche Befestigungmittel können zum Beispiel als Laschen an dem Elektrogehäuse und den Positionen der Laschen an dem Elektronikgehäuse entsprechende Bohrungen mit Gewinde an dem Gehäuse des Stellgliedes, oder umgekehrt, ausgebildet sein, wobei zur Einbringung von Bohrungen mit Gewinde das serienmäßige Gehäuse des Stellgliedes mit nur wenigen zusätzlichen Arbeitsschritten modifiziert werden müßte. Denkbar wäre auch eine geringfügige Modifikation der Form für das Gehäuse des Stellgliedes, um zum Beispiel diese Bohrungen (oder Laschen, wenn entsprechende Bohrungen am Elektronikgehäuse vorgesehen werden) beim Gießen des Gehäuses schon einzubringen.In a further development of the invention, the housing and / or the electronics housing Fastening means for mutual attachment to each other. Such fastening means may, for example, as tabs on the electrical housing and the positions of the tabs on the electronics housing corresponding Holes with thread on the housing of the actuator, or vice versa, be formed, wherein for the introduction of threaded holes the standard housing of the actuator with only a few additional steps would have to be modified. Conceivable would be a minor Modification of the shape of the housing of the actuator, for example, this Holes (or tabs, if appropriate holes on the electronics housing be provided) already bring in the casting of the housing.

In Weiterbildung der Erfindung ist die Steuer- und/oder Auswerteelektronik hochtemperaturfest. Dies hat den Vorteil, daß das der Betrieb des Steuergerätes, das nun im Ansaugbereich der Brennkraftmaschine angeordnet ist, wo hohe Temperaturen herrschen, zuverlässig arbeitet, so daß auf zusätzliche Isolationen des Elektronikgehäuses verzichtet werden kann. Unter hohen Temperaturen, die im Motorraum des Fahrzeuges herrschen, sind beispielsweise solche Temperaturen in einem Bereich von 80° bis 120° C zu verstehen.In development of the invention, the control and / or evaluation is high temperatures. This has the advantage that the operation of the control unit, which is now arranged in the intake of the internal combustion engine, where high Temperatures prevail, works reliably, allowing for extra insulation the electronics housing can be dispensed with. Under high temperatures, which prevail in the engine compartment of the vehicle, such as those Temperatures in a range of 80 ° to 120 ° C to understand.

In alternativer oder ergänzender Ausgestaltung der Erfindung ist das Elektronikgehäuse gegen hohe Temperaturen isoliert. Auch damit ist sichergestellt, dass eine nicht unbedingt hochtemperaturfeste Elektronik eingesetzt werden kann, was durch eine entsprechende Isolation des Elektonikgehäuses erreicht wird. Denkbar ist selbstverständlich auch eine Kombination der beiden genannten Maßnahmen, daß nämlich die Steuer- und/oder Auswerteelektronik hochtemperaturfest ausgebildet ist und das Elektronikgehäuse gegen hohe Temperaturen isoliert ist. Darüber hinaus ist es möglich, daß die Elektronik gekühlt wird, insbesondere das deren Verlustwärme durch den Luftstrom im Ansaugbereich und/oder durch sonstige Maßnahmen (wie zum Beispiel der Einsatz eines Lüfters) abgeführt wird.In an alternative or supplementary embodiment of the invention, the electronics housing isolated against high temperatures. This also ensures that that not necessarily high temperature resistant electronics are used can, what achieved by a corresponding insulation of the electronics housing becomes. Of course, a combination of the two mentioned is also conceivable Measures, namely that the control and / or evaluation electronics is formed high temperature resistant and the electronics housing against high Temperatures is isolated. In addition, it is possible that the electronics cooled is, in particular their loss heat through the air flow in the intake and / or other measures (such as use a fan) is dissipated.

In Weiterbildung der Erfindung ist das Elektronikgehäuse staub- und/oder feuchtigkeitsdicht ausgebildet, wobei diese staub- und/oder feuchtigkeitsdichte Ausbildung auch für die schon erwähnte Kupplung von Bedeutung ist.
