Description

Die Erfindung bezieht sich auf eine etwa kreisförmige Drosselklappe in der Auspuffleitung eines Fahrzeugmotors, die zur Verstärkung der Bremswirkung in einem kugelartigen Gehäuse um eine durch die Kugelmitte gehende Achse drehbar ist.The invention relates to an approximately circular throttle valve in the exhaust pipe of a vehicle engine, which increases the braking effect rotatable in a spherical housing around an axis passing through the center of the sphere is.

Vorrichtungen der vorbeschriebenen Art sind bekannt. Bei ihnen ist das Gehäuse zwecks Einbringung der Drosselklappe geteilt. Die Teilung erfordert eine Bearbeitung der Anlageflächen der Gehäuseteile und Mittel zur Verbindung derselben. Beides soll gemäß der Erfindung vermieden werden.Devices of the type described above are known. Is with them the housing divided for the purpose of introducing the throttle valve. The division requires a processing of the contact surfaces of the housing parts and means for connecting the same. According to the invention, both should be avoided.

Die Erfindung besteht darin, daß das ungeteilte Gehäuse zwecks Einführung der Drosselklappe in einer Längsmittelebene an gegenüberliegenden Seiten Nuten besitzt. Die Nuten liegen vorzugsweise an der Stelle der Drosselklappenachse. Sie könnten aber auch gegenüber der Achsebene im Winkel versetzt sein.The invention is that the undivided housing for the purpose of introduction the throttle valve has grooves on opposite sides in a longitudinal center plane. The grooves are preferably at the point of the throttle valve axis. You could but also be offset at an angle with respect to the axial plane.

Es ist damit zu rechnen, daß infolge der hohen Temperaturen der Auspuffgase und infolge chemischer Einwirkung die Drosselklappe sich auf der Achse festsetzt und dann nicht mehr gelöst werden kann. Um den Ausbau im Falle einer notwendig werdenden Reparatur zu ermöglichen, kann man die Klappe aus einem z. B. keramischen Werkstoff herstellen, der für diesen Fall eine Zertrümmerung zuläßt.It is to be expected that as a result of the high temperatures of the exhaust gases and as a result of chemical action, the throttle valve becomes stuck on the axle and then can no longer be resolved. To expand in the event that it becomes necessary To enable repair, you can remove the flap from a z. B. ceramic material produce, which allows a shattering in this case.

Eine andere Möglichkeit für den Ausbau der festgebrannten Drosselklappe besteht in einer geteilten Ausführung der Klappe, derart, daß sie in Teilen von der Achse gelöst werden kann.Another way to remove the burnt-on throttle valve consists in a split design of the flap, such that it is in parts of the axis can be solved.

Die Zeichnung zeigt ein Ausführungsbeispiel der erfindungsgemäßen Drosselklappe.The drawing shows an embodiment of the invention Throttle.

Abb. i ist ein Längsquerschnitt durch das Gehäuse mit Ansicht gegen die Drosselklappe und Abb. 2 eine dazugehörige Draufsicht auf das Gehäuse ohne die Klappe; in Abb. 3 ist ein weiterer Längsschnitt durch das Gehäuse rechtwinklig zur Drosselklappenachse wiedergegeben; in den Abb. q. und 5 ist die Drosselklappe in einer Draufsicht und einer Endansicht dargestellt.Fig. I is a longitudinal cross-section through the housing with a view against the throttle valve and Fig. 2 a corresponding top view of the housing without the Flap; in Fig. 3 is a further longitudinal section through the housing at right angles to Throttle valve axis reproduced; in fig. q. and 5 is the throttle in shown in a top view and an end view.

Die Drosselklappe i hat außen eine zylindrische Form. An der Stelle der Durchführung der Achse 2 hat die Drosselklappe beiderseits ebene Stirnflächen 3, gegen die die vorzugsweise aus Preßkohle hergestellten Lagerbuchsen q. mit ihren inneren Stirnflächen abdichten.The throttle valve i has a cylindrical shape on the outside. At the point the implementation of axis 2, the throttle valve has flat end faces on both sides 3, against which the bearing bushes, preferably made of compressed carbon, q. with their seal inner end faces.

Das Gehäuse 5, das mit seinen kegeligen Flächen 6 zwischen Teilen der Auspuffleitung dichtend eingespannt wird, hat innen eine annähernd kugelzonenartige Form 7, die jedoch mit einer Verdrehung der Drosselklappe i aus der mittleren Querstellung einen sich allmählich erweiternden Spalt freigibt. Für die Einführung der Drosselklappe i in das Gehäuse sind beiderseits Nuten 8 vorgesehen, die zur Erleichterung der Bearbeitung im Räumverfahren über die ganze Höhe durchgeführt sind.The housing 5, with its conical surfaces 6 between parts the exhaust line is clamped tightly, has an approximately spherical zone-like inside Form 7, however, with a rotation of the throttle valve i from the central transverse position releases a gradually widening gap. For the introduction of the throttle valve i in the housing on both sides grooves 8 are provided to facilitate the Machining in the broaching process has been carried out over the entire height.

Der Zusammenbau gestaltet sich folgendermaßen: Die linke Lagerbuchse q. wird von innen in die Gehäusebohrung eingesetzt. Darauf wird die Drosselklappe i durch die Nuten eingeführt und anschließend die Achse :2 von der rechten Seite her durchgesteckt. Die Mitnahme der Klappe geschieht durch einen vorher in die Achse eingeschlagenen Stift 9, der in einen Querschlitz der Klappe eingreift. Schließlich werden die rechte Lagerbuchse q. und die einzelnen Teile der Stopfbuchse io eingesetzt.The assembly is as follows: The left bearing bush q. is inserted into the housing bore from the inside. This will be the throttle i inserted through the grooves and then the axis: 2 from the right side put through. The flap is taken along beforehand in the axis hammered pin 9, which engages in a transverse slot in the flap. In the end the right bearing bush q. and the individual parts of the stuffing box are inserted.
