Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Vorrichtung zur Leistungssteuerung einer Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1.The invention is based on one Device for controlling the output of an internal combustion engine the preamble of claim 1.
Eine solche Vorrichtung ist allgemein
unter der Bezeichnung E-Gas bekannt und beispielsweise als Lastverstellvorrichtung
in der
Um ein sicheres Ausfahren der Drosselklappe aus der Leerlaufstellung unter der Wirkung der Notluftfeder zu gewährleisten, ist die Drosselklappe als sog. "anlaufende Drosselklappe" konzipiert, die in der Leerlaufstellung noch eine gewisse Schräglage gegenüber der Achse des Strömungswegs für das strömende Medium aufweist. Eine solche Schrägstellung der Drosselklappe in der Leerlaufstellung beträgt je nach Ausführung bis zu ca. 8° gegenüber einer rechtwinklig zur Strömungsachse des Strömungswegs ausgerichteten Ebene, die die Bezugsebene für die Schwenkwinkelangabe der Drosselklappe darstellt. Damit steht für den Regelbereich der Drosselklappe nur noch ein Schwenkbereich von ca. 82° zwischen Leerlaufstellung und Vollaststellung zur Verfügung, so daß die Regelkennlinie der Drosselklappe zur Drosselung des strömenden Mediums relativ steil verläuft.To safely extend the throttle valve to ensure from the idle position under the action of the emergency air spring is the throttle valve as a so-called Throttle valve "designed, which in the idle position is still a certain inclined position compared to the Axis of the flow path for the flowing medium having. Such an inclination depending on the version, the throttle valve in the idle position is up to to about 8 ° compared to one perpendicular to the flow axis the flow path aligned plane, which is the reference plane for the swivel angle specification of the Throttle valve represents. This stands for the control range of the throttle valve only a swivel range of approx. 82 ° between idle position and Full load position available, So that the Control characteristic of the throttle valve for throttling the flowing medium runs relatively steep.
Es sind auch Vorrichtungen zur Leistungssteuerung einer Brennkraftmaschine bekannt, bei denen die Drosselklappe als sog. durchtauchende Drosselklappen konzipiert ist. In diesem Fall ist die Leerlaufstellung der Drosselklappe so festgelegt, daß die Drosselklappe bei Einnahme ihrer Leerlaufstellung in der Bezugsebene liegt, die sich rechtwinklig zur Achse des Strömungswegs erstreckt. Der Schwenkwinkel der Drosselklappe gegenüber der Bezugsebene beträgt damit Null Grad. Die Notlaufstellung der Drosselklappe befindet sich auf der von der Vollastseite abgekehrten Seite der Bezugsebene, so daß die Drosselklappe in jedem Fall die Leerlaufstellung durchfahren muß, um in die Notlaufstellung zu gelangen. Zur Überführung der Drosselklappe in die Notlaufstellung ist nur noch eine einzige Feder in der Notlaufeinrichtung erforderlich, die über den gesamten Verstellweg der Drosselklappe wirkt. Der Verstellbereich der Drosselklappe zwischen Leerlauf- und Vollaststellung erstreckt sich jetzt über volle 90°, so daß sich eine gegenüber der Vorrichtung mit anlaufender Drosselklappe wesentlich flachere Regelkennlinie zur Drosselung des strömenden Mediums ergibt. Diesen beiden Vorteilen steht der Nachteil gegenüber, daß beim "Durchtauchen" der Drosselklappe durch die Bezugsebene es zu Verklemmungen kommen kann, wenn die Drosselklappe und das Gehäuse nicht äußerst präzise gefertigt sind.They are also power control devices an internal combustion engine known in which the throttle valve as so-called plunging throttle valves is designed. In this case the idle position of the throttle valve is set so that the throttle valve when taking their idle position lies in the reference plane, the extends at right angles to the axis of the flow path. The swivel angle opposite the throttle valve the reference plane with it zero degrees. The throttle valve is in the emergency running position on the side of the reference plane facing away from the full load side, so that the Throttle must in any case pass through the idle position in order to reach the emergency running position. For transferring the throttle valve into the The emergency running position is only a single spring in the emergency running device required that over the entire adjustment path of the throttle valve acts. The adjustment range the throttle valve extends between idle and full load over now full 90 °, so that itself one opposite the device with starting throttle valve much flatter Control characteristic curve for throttling the flowing medium results. this The two advantages are offset by the disadvantage that when the throttle valve "plunges" through the reference plane there may be jams if the throttle valve and that casing not manufactured with extreme precision are.

Vorteile der ErfindungAdvantages of invention
Die erfindungsgemäße Vorrichtung zur Leistungssteuerung einer Brennkraftmaschine mit den Merkmalen des Anspruchs 1 hat den Vorteil, daß einerseits der Drosselklappe ein maximaler Verstellbereich zwischen Leerlaufstellung und Vollaststellung von 90° zur Verfügung steht und damit die Vorrichtung eine flache Regelkennlinie zur Drosselung des strömenden Mediums erhält, wie sie bei der Verstellvorrichtung mit "durchtauchender Drosselklappe" vorhanden ist, und andererseits die bei der Vorrichtung mit "durchtauchender Drosselklappe" stets gegenwärtige Klemmgefahr zwischen Drosselklappe und Gehäuse beim Durchtauchen durch die Bezugsebene gebannt ist, da die Notlaufstellung im Regelbereich oberhalb der Leerlaufstellung festgelegt ist und damit ein Durchtauchen der Drosselklappe nur im Fehlerfall, z.B. bei Reglerüberschwinger oder sonstigen fehlerhaft zu kleinen Stellwinkeln auftritt. Ebenso wie die Vorrichtung mit "anlaufender Drosselklappe" benötigt die erfindungsgemäße Vorrichtung beide Federn in der Notlufteinrichtung.The device for power control according to the invention an internal combustion engine with the features of claim 1 has the Advantage that on the one hand the throttle valve has a maximum adjustment range between idle position and full load position of 90 ° disposal stands and thus the device has a flat control characteristic for throttling the pouring Receives medium, as it is present in the adjusting device with a "throttle valve", and on the other hand, the danger of pinching, which is always present in the device with a "throttle flap" between throttle valve and housing is immersed in diving through the reference plane, because the emergency running position is set in the control range above the idle position and so that the throttle valve only plunges in the event of a fault, e.g. with controller overshoot or other incorrectly occurring too small setting angles. As well like the device with "tarnishing Throttle valve "needs the device according to the invention both Springs in the emergency air system.
Durch die in den weiteren Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Anspruch 1 angegebenen Vorrichtung möglich.By the measures listed in the other claims are advantageous developments and improvements in the claim 1 specified device possible.
Gemäß einer vorteilhaften Ausführungsform der Erfindung ist der Schwenkweg der Stellwelle über die Leerlaufstellung der Drosselklappe hinweg durch einen unteren mechanischen Anschlag begrenzt, der am Gehäuse so festgelegt ist, daß die Drosselklappe beim Anschlagen der Stellwelle an dem unteren mechanischen Anschlaggegenüber der Bezugsebene für die Schwenkwinkel der Drosselklappe um einen nur kleinen Schwenkwinkel auf die vom Notlauf abgekehrte Seite der Bezugsebene hin verschwenkt ist. Dieser untere mechanische Anschlag leistet Hilfestellung bei der Montage und erstmaligen Justierung der Vorrichtung. Der untere mechanische Anschlag wird im normalen Betrieb nicht mehr angefahren, da die Drosselklappe "nichtdurchtauchend" arbeitet und der die Leerlaufstellung der Drosselklappe festlegende, sog. untere elektrische Anschlag in oder unmittelbar vor der Bezugsebene der Drosselklappe liegt, verhindert aber im Fehlerfall ein zu großes Überschwingen der Drosselklappe über die Leerlaufstellung hinaus.According to an advantageous embodiment of the invention, the swivel path of the actuating shaft is over the idle position of the throttle valve is limited by a lower mechanical stop, which is fixed to the housing so that the throttle valve when the control shaft strikes the lower mechanical stop compared to the reference plane for the swivel angle of the throttle valve by only a small swivel angle on the side away from the emergency mode Reference plane is pivoted. This lower mechanical stop provides assistance during the assembly and first adjustment of the device. The lower mechanical stop is no longer approached in normal operation, since the throttle valve operates "non-diving" and the so-called lower electrical stop, which determines the idle position of the throttle valve, is in or immediately before the reference plane of the throttle valve, but prevents excessive overshoot in the event of a fault the throttle valve beyond the idle position.
