Description

Die Erfindung betrifft eine Anordnung einer Drosselklappe in einem Abgaskanal einer Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to an arrangement of a throttle valve in an exhaust duct Internal combustion engine according to the preamble of claim 1.

Aus der DE-A1 37 07 904 ist bereits eine Drosselklappenanordnung bekannt, bei der die Drosselklappe in Schließstellung mit beiden Klappenseiten gegen Axialflächen einer im Abgaskanal bestehenden Rippe anschlägt.A throttle valve arrangement is already known from DE-A1 37 07 904, in which the Throttle valve in closed position with both flap sides against axial surfaces one in Exhaust duct strikes the existing rib.

Die stromauf und stromab der Drosselklappe bestehenden Axialflächen entstehen durch Hinterschnitte, die in bezug auf die Drosselklappenwellenlagerung äußerst genau hergestellt werden müssen, da in Schließstellung theoretisch eine Überbestimmung der Drosselklappenhalterung besteht, d. h. die Drosselklappe liegt entweder nur mit einer Klappenseite gegen eine Axialfläche an, andernfalls ist die Drosselklappenwelle unter Spannung montiert worden.The axial surfaces upstream and downstream of the throttle valve are created by Undercuts that are extremely accurate in relation to the throttle valve shaft bearing have to be manufactured, because in the closed position, an overdetermination of the Throttle valve holder exists, d. H. the throttle valve is either only with one Flap side against an axial surface, otherwise the throttle valve shaft is under Voltage has been mounted.

Hierdurch entsteht im ersten Falle eine nicht tolerierbare Leckage oder im zweiten Fall eine Schwergängigkeit der Betätigung.This creates an intolerable leak in the first case or one in the second case Stiffness of operation.

Daher ist aus dieser Druckschrift ein Vorschlag zur Lagerung einer Drosselklappenwelle mittels kalottenförmig ausgebildeter Lagerhülsen bekannt, die sich unter Federkraft an konisch ausgebildeten Gehäusewänden abstützen. Hierdurch können Fluchtungsfehler der beidseits des Abgaskanals bestehenden Lagerbohrungen kompensiert werden. In bezug auf das der vorliegenden Erfindung bestehende Problem stellen diese Maßnahmen keine Lösungsmittel dar.Therefore, from this publication is a proposal for the storage of a throttle valve shaft by means of dome-shaped bearing sleeves known, which are under spring force Support conical housing walls. This can cause misalignment existing bearing bores on both sides of the exhaust duct are compensated. In relation These measures do not pose any problem to the present invention Solvent.

Hiervon ausgehend liegt der Erfindung daher die Aufgabe zugrunde, Lösungsmittel aufzufinden, mit denen eine größere Dichtigkeit der Drosselklappen­ anordnung erreicht wird unter Ausschluß von Schwer­ gängigkeit der Betätigung.Proceeding from this, the invention is therefore based on the object of solvents find with which greater tightness of the throttle valves  order is reached with the exclusion of difficult frequency of operation.

Diese Aufgabe ist durch die im Anspruch 1 angege­ benen, kennzeichnenden Merkmale gelöst worden. Vor­ teilhafte Weiterbildungen sind mit den Unteran­ sprüchen angegeben.This task is indicated by in claim 1 benen, characteristic features have been solved. Before partial training is with the Unteran sayings.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend be­ schrieben.An embodiment of the invention is in the Drawing shown and will be below wrote.

Diese zeigtThis shows

Fig. 1 einen Längsschnitt durch ein Drosselgehäuse in Schwenkrichtung der Drosselklappe; Fig. 1 is a longitudinal sectional view of a throttle housing in the pivoting direction of the throttle valve;

Fig. 2 einen Längsschnitt des Gehäuses in Drossel­ klappenwellenrichtung. Fig. 2 shows a longitudinal section of the housing in the throttle valve shaft direction.

Fig. 1 zeigt ein Drosselgehäuse 1 mit Anschluß­ stutzen 2, 3 und einer drehbar gelagerten Drossel­ klappenwelle 4, an der eine Drosselklappe 5 befe­ stigt ist. Die gestrichelt gezeichneten Schwenkbögen 6, 7 der Klappenseiten 8, 9 führen zu Anschlag­ flächen 10, 11 eines Hinterschnittes, an denen die Klappenseiten 8, 9 in Schließstellung der Drossel­ klappe 5 zur Anlage kommen. Fig. 1 shows a throttle body 1 with connecting piece 2 , 3 and a rotatably mounted throttle valve shaft 4 , on which a throttle valve 5 is BEFE Stigt. The dashed curves 6 , 7 of the flap sides 8 , 9 lead to stop surfaces 10 , 11 of an undercut, on which the flap sides 8 , 9 in the closed position of the throttle valve 5 come to rest.

Fig. 2 zeigt die Drosselklappe 5 mit Drosselklap­ penwelle 4, die beiderseits eines Abgaskanals 12 durch eine Lagerbohrung 13 nach außen ragt. Die linke Seite der Drosselklappenwelle 4 ragt durch eine Lagerhülse 14, die unter der Kraft einer Feder 15 gegen eine Axialwand 16 gedrückt wird. Die Feder 15 ist andererseits durch eine in die Lagerbohrung 13 eingesetzte Scheibe 17 abgestützt. Das durch die Scheibe 17 hindurchragende Ende der Drosselklappen­ welle 4 ist mit einem Betätigungshebel 18 verbun­ den. Zwischen Betätigungshebel 18 und Lagerhülse 14 ist eine Feder 19 eingespannt, die die Drosselklap­ penwelle 4 nach außen belastet. Diese stützt sich mit einem Axiallager 20, das durch einen konischen bzw. kugeligen Absatz 21 der Welle 4 und eine kege­ lige Ausnehmung 22 der Lagerhülse 14 gebildet ist, ab. Damit ist die Lagerung der Drosselklappenwelle 4 in Axialrichtung spielfrei. Fig. 2 shows the throttle valve 5 with Drosselklap penwelle 4 , which protrudes on both sides of an exhaust duct 12 through a bearing bore 13 to the outside. The left side of the throttle valve shaft 4 projects through a bearing sleeve 14 which is pressed against an axial wall 16 under the force of a spring 15 . On the other hand, the spring 15 is supported by a disk 17 inserted into the bearing bore 13 . The protruding through the disc 17 end of the throttle valve shaft 4 is verbun with an operating lever 18 . Between the actuating lever 18 and the bearing sleeve 14 , a spring 19 is clamped, which loads the Drosselklap penwelle 4 to the outside. This is supported by an axial bearing 20 , which is formed by a conical or spherical shoulder 21 of the shaft 4 and a conical recess 22 of the bearing sleeve 14 . The throttle valve shaft 4 is thus free of play in the axial direction.

Die rechte Seite der Drosselklappenwelle 4 ist mit­ tels einer zweiten Lagerhülse 14 gelagert, die ebenfalls durch eine eingespannte Feder 15 belastet ist und an einer Axialwand 16 der Lagerbohrung 13 anliegt. Die Bohrung 13 ist hier durch eine ge­ schlossene Scheibe 23 verschlossen. Nach der Mon­ tage der Drosselklappenwelle 4 und der Drossel­ klappe 5 wird die Drosselklappe 5 in ihre Schließ­ stellung bewegt, wodurch die beiden Klappenseiten 8, 9 gegen die Axialfläche 10, 11 der Hinter­ schnitte gedrückt werden. Bei einer vorliegenden Maßabweichung zwischen den Axialflächen 10, 11, der Drosselklappenwellenlagerung bzw. den Bohrungen 13 und der Drosselklappe 5 richtet sich dabei die La­ gerhülse 14 durch radiales Auswandern auf den Axialwänden 16 aus. Die Kraft der Feder 15 ist so bemessen, daß diese ausgerichtete Position der La­ gerhülsen 14 bei normalem Betrieb der Drosselklap­ peneinrichtung nicht verändert wird.The right side of the throttle valve shaft 4 is supported by means of a second bearing sleeve 14 , which is also loaded by a clamped spring 15 and bears against an axial wall 16 of the bearing bore 13 . The bore 13 is closed here by a closed disk 23 ge. After the days of the throttle valve shaft 4 and the throttle valve 5 , the throttle valve 5 is moved into its closed position, whereby the two flap sides 8 , 9 are pressed against the axial surface 10 , 11 of the undercuts. In the event of a dimensional deviation between the axial surfaces 10 , 11 , the throttle valve shaft bearing or the bores 13 and the throttle valve 5 , the La gerhülse 14 is aligned by radial migration on the axial walls 16 . The force of the spring 15 is dimensioned so that this aligned position of the La gerhülsen 14 is not changed during normal operation of the Drosselklap peneinrichtung.

Damit weist die erfinderische Drosselklappenein­ richtung eine geringste Leckage auf und die Dros­ selklappenwelle 4 wird nicht verspannt, wodurch ge­ ringe Betätigungskräfte erreicht sind. Ebenso ist eine mit größeren Toleranzen betreibbare Serienfer­ tigung erreichbar geworden.So that the inventive Drosselklappenein direction has the least leakage and the Dros selklappenwelle 4 is not braced, whereby ge rings actuation forces are reached. Series production that can be operated with greater tolerances has also become achievable.
