Description
Die Erfindung betrifft einen Drosselklappenstutzen mit Gaspedal- und Elektromotorantrieb nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a throttle valve assembly with accelerator and electric motor drive after Preamble of claim 1.
Derartige Drosselklappenstutzen sind bekannt und weisen häufig mehrere Rückstellfedern auf, die die Drosselklappe über Hilfehebel in eine Notlaufstel lung bringen sollen (DE-A1 41 41 104).Such throttle body are known and often have multiple return springs that the Throttle valve via auxiliary lever in an emergency running position should bring lung (DE-A1 41 41 104).
Zu diesem Zweck müssen die Rückstellfedern sorgfäl tig aufeinander abgestimmt werden. Die Summe der in Schließrichtung wirkenden Kräfte der ersten und zweiten Rückstellfeder darf nicht größer sein als die in Öffnungsrichtung wirkende Kraft der dritten Rückstellfeder. Andererseits muß der elektromotori sche Stellantrieb schon für den Leerlaufregelbe reich so stark ausgelegt werden, daß er die Dros selklappe in Öffnungsrichtung gegen die erste und zweite Rückstellfeder und in Schließrichtung gegen die dritte Rückstellfeder verstellen kann.For this purpose, the return springs must be carefully be coordinated with each other. The sum of the in Closing forces of the first and second return spring must not be greater than the force of the third acting in the opening direction Return spring. On the other hand, the electric motor Actuator for idle control be so richly interpreted that he the Dros Selklappe in the opening direction against the first and second return spring and in the closing direction against can adjust the third return spring.
Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, die eingangs genannte Einrichtung so wei terzubilden, daß nur eine Rückstellfeder benötigt wird und Hilfshebel und dergleichen entfallen, daß heißt die Mechanik vereinfacht wird.Proceeding from this, the object of the invention based on the facility mentioned at the beginning terzubilden that only a return spring is required will and auxiliary levers and the like are omitted that is called the mechanics is simplified.
Diese Aufgabe ist durch die im Kennzeichen des Pa tentanspruchs 1 genannten Merkmale gelöst worden. Vorteilhafte Weiterbildungen sind in den Unteran sprüchen angegeben.This task is characterized by the characteristics of Pa Features mentioned 1 have been solved. Advantageous further training are in the Unteran sayings.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird mit Angabe erreich barer Vorteile nachfolgend beschrieben. An embodiment of the invention is in the Drawing shown and is reached with information advantages described below.
Diese zeigtThis shows
Fig. 1 einen Teilschnitt eines Drosselklappenstutzens, Fig. 1 shows a partial section of a throttle valve housing,
Fig. 2 eine Einzelheit aus Fig. 1. FIG. 2 shows a detail from FIG. 1.
Fig. 1 zeigt einen Drosselklappenstutzen 1 mit ei ner Drosselklappenwelle 2, an der eine Drossel klappe 3 und eine Scheibe 4 befestigt sind. Auf dem nach außen ragenden Ende 5 der Drosselklappenwelle 2 ist ein Motorhebel 6 mit einer Buchse 7 aufge schoben und durch einen mit der Welle 2 verbundenen Drosselhebel 8 gesichert. An den Motorhebel 6 greift ein nicht dargestellter Elektromotor über ein Getriebe an, wobei der Elektromotor von einem elektronischen Steuergerät in bekannter Weise ge steuert wird. Fig. 1 shows a throttle valve assembly 1 with egg ner throttle valve shaft 2 , on which a throttle valve 3 and a disc 4 are attached. On the outwardly projecting end 5 of the throttle valve shaft 2 , a motor lever 6 with a bushing 7 is pushed up and secured by a throttle lever 8 connected to the shaft 2 . On the motor lever 6 engages an electric motor, not shown, via a transmission, the electric motor being controlled by an electronic control unit in a known manner.
Der Drosselhebel 8 ist durch eine zwischen Drosselhebel 8 und Motorhebel 6 eingespannte Feder 9 gegen einen Motorhebelanschlag 10 gehalten (Fig. 2) und bei Gaspedalbetätigung über einen vom Motor hebel 6 eingestellten öffnungsbetrag der Drossel klappe 2 hinaus hebt er von diesem ab.The throttle lever 8 is held by an intermediate throttle lever 8 and motor lever 6 clamped spring 9 against a motor lever stop 10 (Fig. 2) and accelerator opening flap 2 beyond a set by the motor lever 6 opening amount of the throttle he takes off from this.
Eine mit der Motorhebelbuchse 7 verbundene Hülse 11 weist einen Schlitz 12 auf, in den ein Ende 13 der zwischen Motor- und Drosselhebel eingespannten Fe der 9 eingeschoben ist, und nimmt eine Klammerfeder 14 auf, die mit ihren beiden Enden 15, 16 einen Mo torhebelzapfen 17 und einen Gehäusezapfen 18 ge meinsam umklammert, wie in Fig. 2 als Einzelheit aus Fig. 1 dargestellt ist.A connected to the motor lever bushing 7 sleeve 11 has a slot 12 , in which one end 13 of the clamped between the engine and throttle lever Fe 9 is inserted, and receives a clamp spring 14 , with its two ends 15 , 16, a Mo torhebelzapfen 17 and a housing pin 18 clutched ge together, as shown in Fig. 2 as a detail from Fig. 1.
Ein nicht dargestellter Gaspedalhebel wandert bei Gaspedalantrieb mit einem Anschlag in die Bewe gungsbahn des Drosselhebels 8 und nimmt diesen zwangsweise mit, so daß die Drosselklappe 2 geöff net wird. Falls der Motorhebel 6 dieser Drossel klappenöffnung nicht ausreichend schnell folgt, hebt der Drosselhebel 8 von dem Motorhebelanschlag 10 ab unter Verspannung der Feder 9.An accelerator pedal lever, not shown, moves with the accelerator pedal drive with a stop in the movement path of the throttle lever 8 and takes it with it, so that the throttle valve 2 is opened. If the engine lever 6 does not follow this throttle valve opening sufficiently quickly, the throttle lever 8 lifts off the engine lever stop 10 with tensioning of the spring 9 .
Der nicht dargestellte Gaspedalhebel kann zusätz lich einen Mitnehmeranschlag aufweisen, der bei Gaspedalrückstellung eine Zwangsschließung der Drosselklappe 2 bewirkt. Hierdurch wird jedoch eine Tempomatfunktion eingeschränkt.The accelerator pedal lever, not shown, can additionally have a driver stop, which causes the throttle valve 2 to be closed when the accelerator pedal is reset. However, this limits a cruise control function.
Fällt der Elektromotorantrieb des Motorhebels 6 oder die zugehörige elektronische Steuerung aus, dann nimmt der Motorhebel 6 eine Stellung ein, die durch den Motorhebel- und den Gehäusezapfen 17, 18 fixiert ist. Diese Position des Motorhebels 6 be wirkt eine Notlauföffnung der Drosselklappe 2. Bei normalem Leerlaufbetrieb ist der Elektromotoran trieb bestrebt, eine Drehzahlregelung der Brennkraftmaschine auszuführen, daß heißt, der Mo torhebel 6 wird hierfür aus der durch den Ge häusezapfen 18 fixierten Stellung in eine eine kleinere Öffnung der Drosselklappe bewirkende Stel lung bewegt, wobei hierbei die Klammerfeder 14 ver spannt wird.Falls out of the electric motor drive of the motor lever 6 or the associated electronic controller, then the engine 6 receives a lever position which is defined by the Motorhebel- and the housing pin 17, fixed eighteenth This position of the engine lever 6 be an emergency opening of the throttle valve 2nd In normal idle operation, the electric motor drive strives to perform a speed control of the internal combustion engine, that is, the Mo lever 6 is moved from the housing pin fixed by the Ge 18 position into a smaller opening of the throttle valve causing Stel development, with the clamp spring 14th is stretched.
Im Falle einer Tempomatfunktion wird andersherum der Motorhebel 6 im Sinne einer Drosselklappenöff nung verstellt, wobei auch hier die Klammerfeder 14 verspannt wird. Der Elektromotor ist ausgelegt für eine sichere Verstellung des Motorhebels 6, wobei die Klammerfeder 14 in beide Verstellrichtungen das gleiche Klammermoment aufweist, was vorteilhaft für eine geringe Antriebsleistung des Elektromotors ist, daß heißt, dieser ist nur für diese geringe Leistung ausgelegt und benötigt nur einen kleinen Bauraum.In the case of a cruise control function, the other way round, the motor lever 6 is adjusted in the sense of a throttle opening, with the clamp spring 14 also being tensioned here. The electric motor is designed for a safe adjustment of the motor lever 6 , the clamp spring 14 having the same clamp torque in both adjustment directions, which is advantageous for a low drive power of the electric motor, that is, it is only designed for this low power and requires only a small one Installation space.
