Abstract

The pipe section and an exhaust valve bearing are designed as a welded construction. The bearing arrangement of the valve spindle is constructed in cantilever fashion. The valve (1) is retained inside the slotted spindle (6) section. The valve is guided by a valve cut-out (7) on the unslotted spindle section as a snug fit to align the valve in the pipe section. In the closed position the valve stops in the pipe section by its outer wings (8), and in the open position contacts stops (9) in the pipe section when the valve is open.

Description

Die Erfindung betrifft eine Anordnung einer Abgasklappe in einem Rohrabschnitt eines Abgaskanals einer Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1The invention relates to an arrangement of an exhaust flap in a pipe section Exhaust gas duct of an internal combustion engine according to the preamble of claim 1

Derartige Klappen kommen beispielsweise für die Umschaltung des Abgases auf Startkatalysatoren zur Anwendung (DE-C1 41 30 178).Such flaps occur, for example, for switching the exhaust gas Starting catalysts for use (DE-C1 41 30 178).

Sie werden mit sehr heißen Abgasen beaufschlagt, so daß äußerst aufwendige Konstruktionen gerechtfertigt sind, die einer wirtschaftlichen Fertigung entgegen­ stehen.You are exposed to very hot exhaust gases, so that extremely expensive Constructions are justified that oppose economical production stand.

Es ist daher Aufgabe der Erfindung, eine gattungsgemäße Anordnung derart zu gestalten, daß eine wirtschaftliche Fertigung und eine vorteilhafte Anordnung in einer Abgasanlage einer Brennkraftmaschine möglich wird.It is therefore an object of the invention to provide a generic arrangement of this type shape that an economical production and an advantageous arrangement in one Exhaust system of an internal combustion engine is possible.

Diese Aufgabe ist durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst worden. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by the features specified in the characterizing part of claim 1 been solved. Advantageous developments of the invention are specified in the subclaims.

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 zeigtThe drawing shows

Fig. 1 eine erfindungsgemäße Anordnung einer Abgasklappe, Fig. 1 shows an arrangement according to the invention an exhaust flap,

Fig. 2 eine Einzelheit aus Fig. 1. FIG. 2 shows a detail from FIG. 1.

Fig. 1 zeigt eine Anordnung einer Abgasklappe 1 in einem Rohrabschnitt 2 eines Abgaskanals 3 einer Brennkraftmaschine, die von außen durch ein pneumatisches Stellelement 4 betätigt werden kann. Es ist vorgesehen, daß der Rohrabschnitt 2 und eine Abgasklappenlagerung 5 als Schweißkonstruktion ausgeführt sind und die Lagerung einer Klappenwelle 6 fliegend erfolgt, d. h. daß die Lagerung der Klappe 1 bzw. der Welle 6 nur auf einer Seite erfolgt. Hierdurch entfallen bekannte Probleme, die durch Fluchtungsfehler usw. entstehen und nur durch die erwähnten aufwendigen Konstruktionen gelöst werden konnten. Fig. 1 shows an arrangement of an exhaust valve 1 in a tube section 2 of an exhaust passage 3 of an internal combustion engine which can be operated from the outside by a pneumatic control element 4. It is contemplated that the tube section 2 and an exhaust damper bearing 5 are designed as a welded construction and is carried out the storage of a clapper shaft 6 on the fly, that is, the mounting of the valve 1 and the shaft 6 is effected only on one side. This eliminates known problems that arise from misalignments, etc. and could only be solved by the complex designs mentioned.

Es ist vorgesehen, daß die Abgasklappe 1 innerhalb der geschlitzten Welle 6 gehalten und durch einen Klappenausschnitt 7 auf der ungeschlitzten Welle 6 im Paßsitz zur Ausrichtung der Abgasklappe 1 im Rohrabschnitt 2 geführt ist, daß die Abgasklappe 1 im Rohrabschnitt 2 mit ihren äußeren Flügelseiten 8 anschlägt, wenn sie in Schließ­ stellung gelangt und gegen im Rohrabschnitt angeordnete Anschläge, wenn sie in Öffnungsstellung gelangt.It is provided that the exhaust flap 1 is held within the slotted shaft 6 and is guided by a flap cutout 7 on the unslit shaft 6 in a snug fit for aligning the exhaust flap 1 in the pipe section 2 such that the exhaust flap 1 strikes in the pipe section 2 with its outer wing sides 8 when it comes into the closed position and against stops arranged in the pipe section when it comes into the open position.

Es ist vorgesehen, daß die Klappenlagerung an ihrem äußeren Teil einen Absatz 10 aufweist, gegen den ein Halteblech 11 für das Stellelement 4 angelegt und ver­ schweißt ist. Die Welle 6 ist innerhalb der Klappenlagerung 5 durch die Klappe 1 und einen Klappenbetätigungshebel 12 axial fixiert, wobei die Klappe 1 innerhalb des Wellenschlitzes durch eine die Schlitze und eine Klappenbohrung 13 durchdringende Schraube 14 kraftschlüssig gehalten und durch eine Verschweißung 15 gesichert ist. It is provided that the flap bearing has a shoulder 10 on its outer part, against which a holding plate 11 is placed for the actuating element 4 and is welded ver. The shaft 6 is axially fixed within the flap bearing 5 by the flap 1 and a flap actuating lever 12 , the flap 1 being held non-positively within the shaft slot by a screw 14 penetrating the slots and a flap bore 13 and secured by a weld 15 .

Mit der erfindungsgemäßen Anordnung der Abgasklappe liegt eine Ausführung vor, die preiswert herzustellen ist, gewichtsmäßig sehr leicht ist und beispielsweise durch Einschweißen in die Abgaskanalrohre sehr einfach und platzsparend in das Ab­ gaskanalsystem integriert werden kann.With the arrangement of the exhaust flap according to the invention, there is an embodiment which is inexpensive to manufacture, very light in weight and, for example, by Welding into the exhaust duct pipes is very easy and space-saving in the exhaust gas duct system can be integrated.
