Description
Die Erfindung betrifft eine Luftklappensystemvorrichtung zur gesteuerten Zumessung von Verbrennungsluft in einer Brennkraftmaschine, bei der in einem Drosselklappengehäuseelement ein mit einem Drosselklappenwellenelement verbundenes Drosselklappenelement wenigstens mit einem Gegenfederrelement durch eine Gegenfederbewegung zu verstellen ist.The invention relates to an air damper system device for the controlled metering of combustion air in an internal combustion engine, in which in a throttle valve housing element with a throttle valve shaft element connected throttle valve element at least with a counter spring element can be adjusted by a counter spring movement.
Eine Vorrichtung der eingangs genannten
Art ist aus der
Aus der
Eine Einrichtung, die ähnlich wie
die vorhergenannte aufgebaut ist und ebenfalls zwei Federn einsetzt,
ist aus der
Diesen drei bekannten Lösungen ist gemeinsam, daß Spiralfedern zum Einsatz kommen, die bruchanfällig sind. Außerdem haben die Spiralfedern eine Federkraft, die exponentiell ansteigt.These three known solutions are common that spiral springs are used that are prone to breakage are. Moreover the coil springs have a spring force that increases exponentially.
Aus der
Letztendlich wird in der
Es stellt sich deshalb die Aufgabe, eine Luftklappenvorrichtung der eingangs genannten Art so weiterzuentwickeln, daß deren Drosselklappenelement einfach und sicher verstellbar ist.It is therefore the task to further develop an air damper device of the type mentioned at the outset, that their Throttle valve element is easily and safely adjustable.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst.According to the invention, this object is achieved by Features of claim 1 solved.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß das Flachband-Gegenfederelement durch seinen Ω-förmigen Federbogen eine Federkurve aufweist, die im wesentlichen linear ansteigt. Hierdurch lassen sich die Stellkräfte genau und zielgerichteter übertragen. Darüber hinaus ermöglicht die Ω-förmige Form des Federbogens eine Vorspannkraft, die das Drosselklappenelement in einem solchen Öffnungswinkel hält, daß ein Limp-home-Betrieb bei einem Ausfall des Stellmotors mög lich ist. Darüber hinaus wird gewährleistet, daß das Drosselklappenelement nicht in der Drosselklappenausnehmung des Drosselklappengehäuses bei tieferen Temperaturen festfrieren kann.The advantages achieved with the invention consist in particular that the Ribbon counter spring element with a spring curve due to its Ω-shaped spring arch which increases substantially linearly. Let her through the positioning forces exactly and more targeted transfer. About that allows beyond the Ω-shaped shape of the spring arch a biasing force that the throttle valve element in such an opening angle considers that a limp home operation in the event of a servomotor failure. Furthermore is guaranteed that this Throttle valve element not in the throttle valve recess of the throttle body freeze at lower temperatures.
Am Federbogen des Flachband-Gegenfederelements kann wenigstens ein Halteelement angeordnet sein. Hierdurch läßt sich das Federelement leicht und sicher positionieren.On the spring arch of the flat band counter spring element can be arranged at least one holding element. This allows position the spring element easily and securely.
Als Halteelement kann der Federbogen an einem Ende zu einem Zapfenhaltebogen gebogen werden. An seinem gegenüberliegenden Ende kann eine Halteklammer angeformt sein. Sowohl die Halteklammer als auch der Zapfenhaltebogen sichern einen genauen Halt des Federbogenelements.The spring arch can be used as a holding element bent at one end to form a cone tie. On his opposite A retaining clip can be formed on the end. Both the retaining clip as well as the pin retaining arch ensure a precise hold of the spring arch element.
Die Halteklammer kann im wesentlichen U-förmig ausgebildet sein. Hierdurch ist eine sichere Befestigung möglich.The retaining clip can be essentially U-shaped his. This enables secure attachment.
Das Flachband-Gegenfederelement kann mit seinem Zapfenhaltebogen an einem auf einer Zapfenplatte angeordneten Federhaltezapfen positioniert werden. Die Zapfenplatte kann mit dem Wellenelement verbunden sein. Mit seiner Halteklammer kann das Flachband-Gegenfederelement an einer mit dem Drosselklappenwellenelement verbundenen Zahnkranzeinheit wenigstens teilweise vorgespannt angeordnet sein. Die Uförmig ausgebildete Halteklammer sorgt dabei für einen sicheren Sitz an der Zahnkranzeinheit. Der Haltezapfenbogen hingegen läßt sich leicht hinter den Haltezapfen klemmen. Hierdurch ist eine einfache Montage des Flachbands-Gegenfederelements möglich.The flat ribbon counter spring element can be used its cone retaining arch arranged on a cone plate Spring retaining pins are positioned. The spigot plate can with be connected to the shaft element. With its retaining clip, it can Ribbon counter spring element on one with the throttle valve shaft element connected ring gear unit is arranged at least partially biased his. The U-shaped trained bracket ensures a secure fit on the sprocket unit. The retaining pin arch, however, can clamp slightly behind the retaining pin. This makes it easy Assembly of the flat band counter spring element possible.
