Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem Drosselklappenstutzen nach dem Oberbegriff des Anspruchs 1.The Invention is based on a throttle body according to the preamble of claim 1.
Durch
die deutsche Offenlegungsschrift
Die Montage des Drosselklappenstutzens ist sehr aufwändig, und die Prüfung des Potentiometers kann praktisch erst nach erfolgtem Anbau an den Drosselklappenstutzen durchgeführt werden. Der Montageaufwand bei diesem Drosselklappenstutzen ist arbeitsaufwendig und schwer automatisierbar.The Mounting the throttle body is very complex, and the test of the Potentiometers can practically only after successful attachment to the throttle body carried out become. The assembly effort in this throttle body is laborious and difficult to automate.
Die
Vorteile der ErfindungAdvantages of the invention
Der erfindungsgemäße Drosselklappenstutzen mit den kennzeichnenden Merkmalen des Anspruchs 1 bietet demgegenüber den Vorteil, daß die Montage des Drosselklappenstutzens mit dem elektrischen Stellmotor wesentlich erleichtert ist. Des weiteren kann das Potentiometer bei Bedarf vor Anbau des Deckels an den Drosselklappenstutzen geprüft werden. Der am Deckel vorgesehene Motorsteckkontakt, der mit einem mit dem Stellmotor verbundenen Motorgegensteckkontakt elektrisch gekoppelt werden kann, erleichtert die elektrische Kontaktierung des Stellmotors auf vorteilhafte Weise.Of the throttle body according to the invention with the characterizing features of claim 1 offers the other hand Advantage that the assembly of the throttle body with the electric actuator essential is relieved. Furthermore, the potentiometer can if necessary before fitting the cover to the throttle body. The provided on the cover motor plug contact, with a with the Actuator connected motor counter plug contact can be electrically coupled can, facilitates the electrical contact of the servomotor in an advantageous manner.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des Drosselklappenstutzens nach dem Anspruch 1 möglich.By those in the dependent Claims listed measures are advantageous developments and improvements of the throttle body according to claim 1 possible.
Wird mit dem Deckel, dem mindestens einen Schleifer und der mindestens einen Potentiometerbahn eine Vormontagebaugruppe gebildet, so bietet dies den Vorteil, daß die Vormontagebaugruppe unabhängig von den übrigen Teilen der Drosselklappenstelleinheit, insbesondere unabhängig vom Drosselklappenstutzen und der darin drehbar gelagerten Drosselklappe, hergestellt, gelagert und gegebenenfalls geprüft werden kann.Becomes with the lid, the at least one grinder and the at least a potentiometer track formed a pre-assembly, so it offers the advantage that the Pre-assembly module independent from the rest Dividing the throttle valve adjusting unit, in particular independent of Throttle body and rotatably mounted therein throttle valve, can be produced, stored and optionally tested.
Das an den Deckel angeformte elektrische Kupplungsteil bietet den Vorteil, daß die Drosselklappenstelleinheit leicht elektrisch angeschlossen werden kann, wenig Lötarbeiten auszuführen sind und je nach Fahrzeugtyp unterschiedlich lange Kabel angeschlossen werden können.The formed on the lid electrical coupling part offers the advantage that the Throttle positioner easily be connected electrically can do little soldering perform are and depending on the vehicle type different lengths of cable connected can be.
Das Anbringen der mindestens einen Potentiometerbahn auf der Innenseite des Deckels vereinfacht die Herstellung auf vorteilhafte Weise deutlich.The Attaching the at least one potentiometer track on the inside the lid significantly simplifies the production in an advantageous manner.
Durch das elektrische Verbinden einer Leitung über einen federnden elektrischen Kontakt mit der Potentiometerbahn erhält man eine einfache, leicht herstellbare und funktionssichere Verbindung.By the electrical connection of a line via a resilient electrical Contact with the potentiometer track gets you a simple, easy producible and functionally reliable connection.
Wird die Potentiometerbahn vom Deckel zumindest gegen mechanische Angriffe geschützt, beispielsweise als Schutz gegen mechanische Berührung während einer Handhabung des Deckels, dann verbessert dies die Funktionssicherheit vorteilhafterweise beträchtlich.Becomes the potentiometer track from the lid at least against mechanical attacks protected, For example, as protection against mechanical contact during handling of the Lids, then this improves the reliability advantageously considerably.

Beschreibung der AusführungsbeispieleDescription of the embodiments
Der Drosselklappenstutzen kann bei jeder Brennkraftmaschine verwendet werden, bei der die Leistung der Brennkraftmaschine mit Hilfe einer verstellbaren Drosselklappe beeinflußt werden soll. Insbesondere kann der Drosselklappenstutzen mit einem die Drosselklappe antreibenden Stellmotor versehen sein. Der Drosselklappenstutzen mit dem integrierten Stellmotor bildet eine Drosselklappenstelleinheit. Die dargestellten Ausführungsbeispiele sind leicht so abwandelbar, daß neben der Verstellung durch den Stellmotor die Drosselklappe beispielsweise auch noch mechanisch vom Gaspedal verstellt werden kann. Auch eine nur mechanische Kopplung mit dem Gaspedal ist möglich.Of the Throttle body can be used with any internal combustion engine be in which the performance of the internal combustion engine by means of a adjustable throttle should be affected. Especially can the throttle body with a throttle driving the Actuator be provided. The throttle body with integrated Actuator forms a throttle actuator unit. The illustrated embodiments are easily so changeable that beside the adjustment by the servomotor the throttle, for example can also be adjusted mechanically by the accelerator pedal. Also one only mechanical coupling with the accelerator pedal is possible.
In der Zeichnung sind verschiedene Bereiche des Drosselklappenstutzens nicht dargestellt, damit andere Bereiche mit möglichst großem Maßstab gezeigt werden können.In the drawing are different areas of the throttle body not shown, so that other areas can be shown with the largest possible scale.
