Abstract
Description
Die Erfindung betrifft ein Saugrohr zur Zuführung von Verbrennungsluft zu einer Brennkraftmaschine mit einem vom Sammelrohr zum Luftfilter ge richteten Einlaßstutzen einer Luftansaugleitung, in dem sich eine Dros selklappenanordnung befindet.The invention relates to a suction pipe for supplying combustion air an internal combustion engine with a ge from the manifold to the air filter directed inlet connection of an air intake line, in which a Dros Selklappenanordnung located.
Eine solche Einrichtung entspricht dem allgemeinen Stand der Technik. Saugrohre müssen entsprechend der Vielfalt der Fahrzeuge und der Ein bausituationen jeweils den Gegebenheiten in ihrer Geometrie angepaßt werden. Dies verlangt auch eine Anpassung der verwendeten Drossel klappenstutzen, die entsprechend der Ausbildung der Saugrohre selbst bei gleichen Klappendurchmessern unterschiedliche Flanschbilder oder luftfilterseitig unterschiedlich gestaltete Kupplungen aufweisen.Such a device corresponds to the general state of the art. Intake pipes must correspond to the variety of vehicles and the one construction situations adapted to the circumstances in their geometry become. This also requires an adaptation of the choke used flap connection, which itself according to the design of the suction pipes with the same valve diameters, different flange patterns or have differently designed couplings on the air filter side.
Der Erfindung liegt die Aufgabe zugrunde, das Konzept einer Saugrohr gestaltung aufzufinden, das eine möglichst breite Verwendung eines ein heitlichen Drosselkappenstutzens gestattet.The invention has for its object the concept of a suction pipe design to find the widest possible use of a uniform throttle cap connector allowed.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst. Vorteil hafte Ausgestaltungen und ein zur Realisierung der Erfindung erforderli cher Klappenstutzen sind in den weiteren Ansprüchen beschrieben.This object is achieved with the features of claim 1. Advantage sticky configurations and a necessary for realizing the invention cher flap neck are described in the further claims.
Die Zeichnung zeigt in schematischer Darstellung ein erfindungsgemäßes Saugrohr. Das Saugrohr 1 weist ein Sammelrohr 2 auf, von dem aus Ein zelrohre 3 zu den nicht dargestellten Zylindern führen. Einlaßseitig ist am Sammelrohr 2 ein Einlaßstutzen 4 angeschraubt oder angeformt. Senk recht zur Achse des Einlaßstutzens ist ein diesen schneidender Rohrstut zen 5 angeformt, dessen Innendurchmesser größer ist als der Innen durchmesser des Einlaßstutzens. The drawing shows a suction pipe according to the invention in a schematic representation. The intake manifold 1 has a manifold 2 , from which a single pipes 3 lead to the cylinders, not shown. Inlet side, an inlet fitting is screwed or integrally formed at the header pipe 4. 2 Perpendicular to the axis of the inlet connector is a zen 5 this intersecting Rohrstut, whose inner diameter is larger than the inner diameter of the inlet connector.
In diesen Rohrstutzen 5 wird ein zylindrischer Drosselklappenstutzen 6 quer eingeschoben. Der Drosselklappenstutzen 6 weist eine zylindrische Bohrung 7 auf, in der auf einer Welle 8 die Drosselklappe 9 angeordnet ist. Die Bohrung 7 entspricht im Innendurchmesser dem Innendurchmes ser des Einlaßstutzens 4. Der Außendurchmesser des zylindrischen Drosselklappenstutzens 6 entspricht dem Innendurchmesser des Rohr stutzens 5.A cylindrical throttle valve connector 6 is inserted transversely into this pipe connector 5 . The throttle valve connector 6 has a cylindrical bore 7 , in which the throttle valve 9 is arranged on a shaft 8 . The bore 7 corresponds in the inner diameter to the inner diameter of the inlet pipe 4th The outer diameter of the cylindrical throttle valve connector 6 corresponds to the inner diameter of the pipe connector 5 .
Der Drosselklappenstutzen 6 weist Zylinderendstücke 10 und 11 auf, wo bei die Drosselklappenwelle 8 zum Beispiel aus dem Zylinderendstück 11 herausragt und mit einem Stellelement zur Betätigung der Drosselklappe verbindbar ist. Dieses Stellelement kann eine mechanische Anlenkung mittels eines Hebels sein oder, wie in diesem Ausführungsbeispiel ein Stellmotor 12, der auf dem Wellenstumpf aufsteckbar und mit dem als Flansch ausgebildeten Zylinderendstück 11 verschraubbar ist. Im Ausfüh rungsbeispiel ist das Zylinderendstück 11 mit einem Flansch 13 versehen, der im Außendurchmesser mit dem Außendurchmesser des Rohrstutzens 5 übereinstimmt.The throttle valve connector 6 has cylinder end pieces 10 and 11 , where the throttle valve shaft 8 projects, for example, from the cylinder end piece 11 and can be connected to an actuating element for actuating the throttle valve. This actuating element can be a mechanical linkage by means of a lever or, as in this exemplary embodiment, an actuating motor 12 which can be plugged onto the stub shaft and screwed to the cylinder end piece 11 designed as a flange. In the exemplary embodiment, the cylinder end piece 11 is provided with a flange 13 , the outer diameter of which corresponds to the outer diameter of the pipe socket 5 .
Um bei der Montage des Drosselklappenstutzens eine Abdichtung ge genüber der Atmosphäre vorzunehmen, ist vorgesehen, daß zwischen diesem Flansch 13 und der Stirnseite 14 des Rohrstutzens 5 eine Dich tung 15 angeordnet ist und das Zylinderendstück 10 unter Beilage einer Dichtung 16 gegen einen eingezogenen Rand 17 der anderen Stirnseite 18 dem Rohrstutzens 5 angedrückt wird.To make a seal ge compared to the atmosphere during the assembly of the throttle valve assembly, it is provided that a device 15 is arranged between this flange 13 and the end face 14 of the pipe socket 5 and the cylinder end piece 10 with a seal 16 against a retracted edge 17 of the other end face 18 of the pipe socket 5 is pressed.
In dieser Position wird der Drosselklappenstutzen 6 in dem Rohrstutzen 5 zum Beispiel durch Arretierelemente 19, die mit Gegenstücken 20 am Rohrstutzen 5 zusammenwirken, fixiert. Die Arretierelemente 19 können radial federnd ausgebildet sein, so daß sie nach dem Durchschub durch den Rohrstutzen 5 bei Erreichen der Position der Ausnehmungen bzw. Gegenstücke 20 in den Freiraum einschnappen. Die flanschseitig darge stellten Arretierstücke 19 verhindern bei einer entsprechend unsymmetri schen Anordnung der Gegenstücke im Rohrstutzen 5 eine falsche Monta ge des Drosselklappenstutzens. Damit ist sichergestellt, daß der Dros selklappenstutzen nur in einer Lage in den Rohrstutzen 5 eingesetzt wer den kann.In this position, the throttle valve connection piece 6 is fixed in the pipe connection piece 5, for example by locking elements 19 , which interact with counterparts 20 on the pipe connection piece 5 . The locking elements 19 can be designed to be radially resilient so that they snap into the free space after being pushed through the pipe socket 5 when the position of the recesses or counterparts 20 has been reached. The flange-side Darge locking pieces 19 prevent a correspondingly asymmetrical arrangement of the counterparts in the pipe socket 5 a wrong Monta ge of the throttle valve assembly. This ensures that the Dros selklappenstutzen used only in one position in the pipe socket 5 who can.
