Description
Die Erfindung betrifft eine elektrisch ansteuerbare Stellvorrichtung nach dem Oberbe griff des Anspruchs 1.The invention relates to an electrically controllable actuator according to the Oberbe handle of claim 1.
Derartige Stellvorrichtungen sind bereits bekannt, bei denen die Übertragung der Stel lung des Gaspedals zur Drosselklappe durch eine elektronische Regelung vorgenommen wird. Dabei wird die Bewegung des Gaspedals durch einen Pedalwertgeber erfaßt und über einen elektronischen Regler und ein mit diesem verbundenes Stellglied, zum Bei spiel einen Elektromotor, in Abhängigkeit von Motorparametern die Drosselklappe verstellt.Such actuators are already known in which the transmission of the Stel Development of the accelerator pedal to the throttle valve made by an electronic control becomes. The movement of the accelerator pedal is detected by a pedal value transmitter and via an electronic controller and an actuator connected to it, for example play an electric motor, depending on engine parameters the throttle valve adjusted.
Bei diesen elektronischen Regelungen ist für den Fall eines Defektes an einem der für die Regelung und Verstellung verantwortlichen Bauteile oder bei Totalausfall des Sy stems eine Sicherheitsfunktion für den Notlauf geschaffen worden, indem die Drossel klappe in Schließstellung gebracht wird. Das bedeutet jedoch, daß bei Einsatz dieser Systeme in Kraftfahrzeuge das Fahrzeug nur noch im Leerlauf betrieben werden kann, der Fahrer also kaum mit eigener Kraft eine Reparaturwerkstatt erreichen wird. Des weiteren ist es unter Umständen lebensgefährlich, wenn dieser Defekt zum Beispiel während eines Überholganges auftritt und dann die Drosselklappe über bisherige Sicherheitsfunktionen in Leerlaufstellung gebracht wird.With these electronic regulations, in the event of a defect in one of the the regulation and adjustment of responsible components or in the event of total failure of the Sy A safety function for emergency operation has been created by the throttle flap is brought into the closed position. However, this means that when using this Systems in motor vehicles the vehicle can only be operated at idle, the driver will hardly ever reach a repair shop on his own. Des further, it may be life-threatening if this defect, for example occurs during an overtaking gear and then the throttle valve over previous ones Safety functions is brought into idle position.
Bei anderen Systemen besteht auch die Möglichkeit, daß bei Blockieren des Getriebes und/oder des Elektromotors die Drosselklappe in einer geöffneten Stellung stehen bleibt, was ebenfalls zu gefährlichen Fahrsituationen führen kann.In other systems there is also the possibility that when the gearbox is blocked and / or the electric motor, the throttle valve is in an open position remains, which can also lead to dangerous driving situations.
Hiervor ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Stellvorrichtung ein gangs genannter Art derart zu gestalten, daß diese aufgezeigten Nachteile vermieden werden.Proceeding from this, the object of the invention is to provide an actuating device gangs mentioned type in such a way that these disadvantages avoided avoided will.
Erfindungsgemäß wird diese Aufgabe durch die im Kennzeichen des Anspruchs 1 ange gebenen Merkmale gelöst. Vorteilhafte Weiterbildungen sind mit den Merkmalen der Unteransprüche genannt.According to the invention this object is achieved by the characterizing part of claim 1 given characteristics solved. Advantageous further developments include the features of Subclaims called.
Der mit der Erfindung erzielte Vorteil besteht insbesondere darin, daß durch den Ein satz einer zusätzlichen mechanischen Verbindung zum Beispiel eines Bowdenzuges zwi schen Drosselklappe und Gaspedal im Störfall ein mit diesem System ausgerüstetes Fahrzeug völlig normal auch in kritischen Verkehrssituationen betrieben werden kann und der Betreiber in der Lage ist, aus eigener Kraft eine Reparaturwerkstatt aufzusu chen.The advantage achieved with the invention is, in particular, that by the one set of an additional mechanical connection, for example a Bowden cable between throttle and accelerator pedal in the event of a malfunction equipped with this system Vehicle can be operated completely normally even in critical traffic situations and the operator is able to visit a repair shop under his own steam chen.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt und wird im folgenden beschrieben.An embodiment of the invention is shown schematically in the drawing and is described below.
Die Zeichnung zeigt eine elektrisch ansteuerbare Stellvorrichtung 1 zum Verstellen ei ner Drosselklappe 2, bestehend aus einem Gaspedal 3, das über ein Gestänge 4 mit ei nem Pedalwertgeber 5 verbunden ist, der über einen Elektromotor 6 und ein Ritzel 7 eine Zahnsegmentscheibe 8 verstellt, wodurch ein Untersetzungsgetriebe gebildet ist, und einer elektrisch betätigbaren Kupplung 9, die zwischen der Zahnsegmentscheibe 8 und der Drosselklappe 2 auf einer Drosselklappenwelle 10 befestigt ist. Am verlänger ten Ende der Drosselklappenwelle 10 befindet sich ein Drosselklappenhebel 11, an dem zum einen eine Rückzugfeder 12 angreift, zum anderen ein Bowdenzug 13 mit einer Zusatzfeder 14 eingehängt ist, der eine Verbindung über das Gestänge 4 zum Gaspedal 3 hat.The drawing shows an electrically controllable adjusting device 1 for adjusting egg ner throttle valve 2 , consisting of an accelerator pedal 3 , which is connected via a linkage 4 with egg nem pedal 5 , which adjusts a toothed segment disk 8 via an electric motor 6 and a pinion 7 , thereby a Reduction gear is formed, and an electrically actuated clutch 9 , which is fixed between the toothed segment disk 8 and the throttle valve 2 on a throttle valve shaft 10 . At the extended end of the throttle valve shaft 10 there is a throttle valve lever 11 , on which a return spring 12 engages, on the other hand a Bowden cable 13 is hooked in with an additional spring 14 , which has a connection via the linkage 4 to the accelerator pedal 3 .
Über eine Stellvorrichtung 1 wird die Drosselklappe 2 gegen eine Schließkraft der Rückzugfeder 12 geöffnet. Hierbei wird die Zusatzfeder im Falle einer voreilenden Gasbetätigung zeitweilig mehr oder weniger gegen das vom Elektromotor ausgeübte Drehmoment gespannt. Im Störfall eines der für die Verstellung verantwortlichen Bauteile oder bei Totalausfall trennt die elektrische Kupplung 9 die Drosselklappe 2 von der Zahnsegmentscheibe 8. Da eine zusätzliche Verbindung zwischen dem Gaspedal 3 und dem Drosselklappenhebel 11 über den Bowdenzug 13 geschaffen wurde, arbeitet der über das Gaspedal 3 gespannte Bowdenzug 13 aufgrund der härter ausgeführten Zusatzfeder 14 gegen die Rückstellkraft der Rückstellfeder 12, und das Kraftfahrzeug ist in jeder Fahrsituation voll funktionsfähig.The throttle valve 2 is opened via a setting device 1 against a closing force of the return spring 12 . In this case, the additional spring is temporarily clamped more or less against the torque exerted by the electric motor in the event of an accelerating gas actuation. In the event of a fault in one of the components responsible for the adjustment or in the event of a total failure, the electrical clutch 9 separates the throttle valve 2 from the toothed segment disk 8 . As an additional connection between the accelerator pedal 3 and the throttle lever 11 has been created about the Bowden cable 13, the tensioned via the accelerator pedal 3 Bowden cable 13 operates due to the harder running auxiliary spring 14 against the restoring force of the return spring 12, and the motor vehicle is fully functional in every driving situation .
Die Drosselklappe 2 kann ebenfalls im Falle einer Nichttrennung der Kupplung 9, zum Beispiel bei unbestromtem Elektromotor, betätigt werden. Die Rückstellfeder 12 ist auch dann in der Lage, die Drosselklappe 2 bei losgelassenem Gaspedal 3 zu schließen.The throttle valve 2 can also be actuated if the clutch 9 is not disengaged, for example when the electric motor is not energized. The return spring 12 is then also able to close the throttle valve 2 when the accelerator pedal 3 is released.
