Abstract
Description
Die Erfindung betrifft ein Schaltsaugrohr für Brennkraftmaschinen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a switching intake manifold for internal combustion engines according to the preamble of claim 1.
Derartige Schaltsaugrohre werden nach dem Stand der Technik (DE-GM 89 14 049) z. B. in der Art betrieben, daß ab einer bestimmten überschrittenen Leistungsabgabe der Brennkraftmaschine die Ansaugkanallängen durch Verstellen von Schaltelementen auf kurz umgeschaltet werden, wodurch im oberen Leistungsbereich die Zylinderfüllung durch freies Ansaugen erleichtert und damit die Leistungsabgabe verbessert wird, wobei im unteren Leistungsbereich die Zylinderfüllung durch den Aufladeeffekt der in den langen Ansaugkanälen schwingenden Gassäule verbessert und dadurch das Motordrehmoment erhöht wird.Such switching suction pipes are according to the prior art (DE-GM 89 14 049) z. B. operated in such a way that from a certain exceeded power output the Internal combustion engine the intake duct lengths by adjusting switching elements can be switched briefly, which means the cylinder filling in the upper performance range facilitated by free suction and thus the power output is improved, whereby in the lower power range, the cylinder filling due to the charging effect in the long suction channels vibrating gas column improved and thereby the Engine torque is increased.
Bei diesen Schaltsaugrohren erfolgt die Umschaltung über Antriebe, die in der Regel auf aus den Schaltsaugrohren herausgeführte Wellen mit Hebeln einwirken. Hierdurch entsteht ein großer Bauteileaufwand, die aus den Gehäusen herausgeführten Wellen verursachen Leckage und durch Lagerspiel und Schwingungsbeschleunigungen Geräusche.In the case of these switching suction pipes, the switchover takes place via drives, which are usually open Use levers to move shafts that come out of the intake manifolds. Hereby there is a large expenditure on components, the shafts leading out of the housings cause leakage and due to bearing play and vibration acceleration Sounds.
Hiervon ausgehend liegt der Erfindung daher die Aufgabe zugrunde, Maßnahmen aufzufinden, mit denen bei reduziertem Bauteileaufwand eine geräusch- und leckagefreie Umschaltung der Saugkanallänge erreichbar wird.Proceeding from this, the invention is therefore based on the object of measures to find, with which a reduced noise and leakage-free switching of the suction channel length is achievable.
Diese Aufgabe ist durch die im Kennzeichen des Patentanspruchs 1 angegebenen Merkmale gelöst. Vorteilhafte Weiterbildungen sind mit den Unteransprüchen angegeben.This object is indicated by the characterizing part of claim 1 Features resolved. Advantageous further developments are with the subclaims specified.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend beschrieben.An embodiment of the invention is shown in the drawing and will described below.
Die Zeichnung zeigt:The drawing shows:
Fig. 1 eine schematische Darstellung eines Schaltsaugrohres, Fig. 1 is a schematic representation of a controlled intake,
Fig. 2 eine alternative Ausführung des Schaltsaugrohrs, Fig. 2 shows an alternative embodiment of the Schaltsaugrohrs,
Fig. 3 einen Schnitt durch das Schaltsaugrohr und die Gehäuseeinheit mit Elektromotor, Fig. 3 a section through the variable intake manifold and the housing unit with electric motor,
Fig. 4 ein Diagramm mit Kennlinien der Bestromung. Fig. 4 is a diagram with characteristics of the energization.
Fig. 1 zeigt schematisch ein Schaltsaugrohr 1 für Brennkraftmaschinen mit einem elek tromotorisch verstellbaren Schaltelement 2 zur Veränderung der Schaltsaugrohrinnen kontur 3 zur Verbesserung der Brennkraftmaschinenleistung in vorgegebenen Drehzahl bereichen. Fig. 1 shows schematically a switching intake manifold 1 for internal combustion engines with an elec tromotorically adjustable switching element 2 for changing the inner intake manifold contour 3 to improve the internal combustion engine performance in predetermined speed ranges.
In der gezeigten Ausführung bewirkt die Änderung der Innenkontur 3 eine Änderung der Saugkanallänge zwischen einem Saugkanaleinlaß 4 und einem Zylindereinlaß 5, in dem das Schaltelement 2 mit Rohrbogenabschnitten 6 von Saugkanaleinlässen 7 kurzer Saugkanäle 8 wegbewegt wird, so daß diese freigegeben werden.In the embodiment shown, causes the change of the inner contour 3 is a modification of the Saugkanallänge between a Saugkanaleinlaß 4 and a cylinder inlet 5 in which it is moved away from the switching element 2 with pipe bend portions 6 of Saugkanaleinlässen 7 short suction channels 8 so that they are released.
Ohne den Bereich der Erfindung zu verlassen, könnte auch eine andere Ausführung vor liegen, beispielsweise könnte das Schaltelement 2 als Drosselklappe ausgeführt sein und eine Saugrohrvolumenänderung bewirken. Without leaving the scope of the invention, there could also be another embodiment, for example the switching element 2 could be designed as a throttle valve and cause a change in the intake manifold volume.
Erfindungsgemäß ist nun vorgesehene daß ein elektromotorischer Antrieb von einem Elektromotor 9 gebildet ist, der über eine Ritzelverzahnung 10 auf eine am Schaltele ment 2 angeordnete Verzahnung 11 einwirkt. Wie in Fig. 1 dargestellt, ist bei dieser Aus führung das Schaltelement 2 drehbar gelagert und die mit ihm verbundene Verzahnung 11 als Zahnradsegment 12 ausgebildet.According to the invention it is now provided that an electromotive drive is formed by an electric motor 9 which acts via a pinion toothing 10 on a toothing 11 arranged on the switching element 2 . As shown in Fig. 1, the switching element 2 is rotatably mounted in this embodiment and the toothing 11 connected to it is designed as a gear segment 12 .
Alternativ zu dieser Ausführung kann jedoch auch vorgesehen werden, daß das Schalt element 2 verschiebbar gelagert ist und die mit ihm verbundene Verzahnung 11 als Zahnstange 13 ausgebildet ist, wie schematisch in Fig. 2 dargestellt ist.As an alternative to this embodiment, however, it can also be provided that the switching element 2 is mounted displaceably and the toothing 11 connected to it is designed as a toothed rack 13 , as is shown schematically in FIG. 2.
Es ist von besonderem Vorteil, wenn, wie in Fig. 3 dargestellt ist, der Elektromotor 9 in einer am Schaltsaugrohr 1 befestigten Gehäuseeinheit 14 angeordnet ist, aus der eine Welle 15 mit der Ritzelverzahnung 10 herausragt und durch eine Schaltsaugrohröffnung 16 in das Schaltsaugrohr 1 ragt und dort mit der Verzahnung 11 am Schaltelement 2 zusammenwirkt.It is particularly advantageous if, as shown in FIG. 3, the electric motor 9 is arranged in a housing unit 14 fastened to the switching intake manifold 1 , from which a shaft 15 with the pinion toothing 10 protrudes and projects through a switching intake manifold opening 16 into the switching intake manifold 1 and there cooperates with the toothing 11 on the switching element 2 .
Diese Ausführung reduziert die Bauteileanzahl und minimiert die Bauteiletoleranzen. Wie dargestellt (Fig. 3) ist die Welle 15 mit der Ritzelverzahnung 10 als Getriebewelle 1 7 ausgeführt, die mit einem Getrieberad 18 verbunden ist, in dessen Verzahnung 1 9 ein Elektromotorritzel 20 eingreift.This version reduces the number of components and minimizes component tolerances. As illustrated (Fig. 3), the shaft running 15 with the pinion teeth 10 as a transmission shaft 1 to 7, which is connected with a gear wheel 18 which engages an electric motor pinion 20 in the toothing 1 9.
Alternativ hierzu kann (nicht extra dargestellt) jedoch die Welle 15 mit Ritzelverzahnung 10 als Elektromotorwelle 20 ausgeführt sein, wobei dann ein entsprechendes Motor drehmoment vorliegen muß.Alternatively, the shaft 15 with pinion teeth 10 can be designed as an electric motor shaft 20 (not shown separately), in which case a corresponding motor torque must be present.
Es ist vorteilhaft, wenn Schaltelement 2 und Verzahnung 11 in einem gemeinsamen Spritzgußvorgang hergestellt sind.It is advantageous if the switching element 2 and the toothing 11 are produced in a common injection molding process.
Wie aus Fig. 1 und 2 entnehmbar ist, ist das Schaltelement 2 durch eine gespannte Fe der 21 in einer Endlage 22 gehalten und kann aus dieser durch den Antrieb bzw. Elek tromotor 9 verstellt werden. Die Feder 21 kann in einer mono- oder bistabilen Anord nung 23 oder 24 eingespannt werden. Die Feder 21 in der monostabilen Anordnung ist in Fig. 1, in der bistabilen Anordnung in Fig. 2 gezeigt. As shown in FIGS. 1 and 2 is removed, the switching element 2 is held in one end position 22 by a tensioned Fe of 21 and can be adjusted from this tromotor by the drive or Elek. 9 The spring 21 can be clamped in a monostable or bistable arrangement 23 or 24 . The spring 21 in the monostable arrangement is shown in FIG. 1, in the bistable arrangement in FIG. 2.
Es ist vorgesehen, daß der Elektromotor 9 durch Spannungs- oder Pulsweitensignalände rung bestromt wird, wobei die Bestromung mit umschaltbarer Polarität erfolgen kann zur Unterstützung der Rückstellkräfte, die von der Feder 121 bewirkt werden.It is provided that the electric motor 9 is energized by voltage or pulse width signal change tion, the energization can be carried out with switchable polarity to support the restoring forces caused by the spring 121 .
Zur Erhöhung der Verstellgeschwindigkeit bei geringstem Stromverbrauch ist vorgesehen, daß die Bestromung entsprechend einer Peak-and-hold-Kennlinie erfolgt, die in Fig. 4 dargestellt ist, in der ein Diagramm gezeigt wird, bei dem über einer Zeitlinie Kennlinien der Bestromung als Spannungssignal (Volt) oder des Pulsweitensignals (%) dargestellt sind, mit umschaltbarer Polarität, und eine Kennlinie der Verstellung in Winkelgrad (GRD).In order to increase the adjustment speed with the lowest power consumption, it is provided that the energization takes place according to a peak-and-hold characteristic curve, which is shown in FIG. 4, in which a diagram is shown in which characteristic curves of the current supply as voltage signal ( Volts) or the pulse width signal (%) are shown with switchable polarity, and a characteristic curve of the adjustment in degrees (GRD).
Durch die erfindungsgemäße Ausbildung ist durch das angespritzte Zahnradsegment 13 und die aufsetzbare Gehäuseeinheit 14 eine Verringerung der Bauteile erreicht worden und darüber hinaus der Ungenauigkeit zusammenwirkender Bauteile.Due to the design according to the invention, the molded gear segment 13 and the attachable housing unit 14 have reduced the number of components and, moreover, the inaccuracy of interacting components.
