Description

Abt. stat. Motorenbau, M a n n h e i m, Carl-Benz-Strasse 5 Nachgiebige Rohrverbindung Die Neuerung bezieht sich auf eine nachgiebige Rohrverbindung insbesondere zwischen einer Brennkraftmaschine und einer Abgasleitung.Dept. stat. Motorenbau, M a n n h e i m, Carl-Benz-Strasse 5 yielding Pipe connection The innovation relates in particular to a flexible pipe connection between an internal combustion engine and an exhaust pipe.

Diese Verbindungen sind vielfach Verdrehbeanspruchungen ausgesetzt, die im allgemeinen nur durch stopfbuchsartige Vorrichtungen ausgleichbar sind. Derartige Stopfbuchsen sind verhältnismäßig aufwendig und außerdem auch nicht völlig dicht.These connections are often exposed to torsional stresses, which can generally only be compensated by gland-type devices. Such Stuffing boxes are relatively expensive and also not completely tight.

Die Aufgabe der Neuerung besteht in der Vermeidung dieser Nachteile. Diese Aufgabe wird neuerungsgemäß an einer nachgiebigen Rohrverbindung der eingangs erwähnten Art durch folgende Kombination von an sich bekannten Merkmalen gelöst. a.) In die Rohrverbindung ist ein Faltenbalg eingeschaltet, der aus auf dem Rohrumfang angeordneten Falten besteht, die sich in Ebenen erstrecken, die sternförmig angeordnet sind und mindestens annähernd parallel zur Rohrachse verlaufen und eine Verdrehung zulassen. b.) In den Faltenbalg nach Merkmal a.) taucht ein Stützrohr ein, daß ein übermäßiges Einknicken der Falten bei Verdrehung verhindert. c.) In die Rohrverbindung ist ein Faltenbalg eingeschaltet, der aus am Rohrumfang angeordneten Falten besteht, die sich in Ebenen erstrecken, die mindestens annähernd senkrecht zur Rohrachse verlaufen und eine Knickung oder eine axiale Längenänderung zulassen..The task of the innovation is to avoid these disadvantages. According to the innovation, this object is achieved in a flexible pipe connection of the introduction mentioned type solved by the following combination of known features. a.) In the pipe connection a bellows is switched on, which is out on the pipe circumference arranged folds that extend in planes that are arranged in a star shape are and run at least approximately parallel to the pipe axis and a twist allow. b.) A support tube dips into the bellows according to feature a.) Prevents excessive buckling of the folds when twisted. c.) In the pipe connection If a bellows is switched on, which consists of folds arranged on the pipe circumference, which extend in planes that are at least approximately perpendicular to the pipe axis and allow a kink or an axial change in length ..

In der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Neuerung dargestellt.In the drawing is an embodiment of the subject matter of Innovation presented.

Fig. 1 zeigt eine Ausführung, die dazu dient, die Verdrehung der Rohrenden gegeneinander auszugleichen. Fig. 2 stellt einen Schnitt längs der Linie A-B in Fig. dar.Fig. 1 shows an embodiment which is used to twist the pipe ends balance against each other. Fig. 2 shows a section along the Line A-B in Fig.

Fig. 3 zeigt eine Ausführung, die sowohl Verdrehungen als auch Knickungen und axiale Längenänderungen ausgleichen kann. s 'Die nachgiebige Rohrverbindung gemäß Fig. 1 und 2 besteht hauptsächlich aus dem Faltenbalg 1, dessen Falten 2 sich in sternförmig angeordneten Ebenen 3 erstrecken, die mindestens annähernd parallel zur Rohrachse 4 verlaufen.. Die Falten 2 sind auf dem Rohrumfang 5 angeordnet. Der Faltenbalg 1 ist an einer Seite mit dem in den Flansch 6 auslaufenden Rohrende 7 an der anderen Seite mit dem Stützrohr 8 verbunden, das sich in den Flansch 9 fortsetzt. Das stützrohr 8 taucht in den Faltenbalg 1 ein, so daß dieser unter dem Einfluß der Verdrehkräfte nicht einknicken kann. Bei der Ausführung nach Fig. 3 besteht die nachgiebige Rohrverbindung außer dem Faltenbalg 1 noch aus einem weiteren Faltenbalg 10, der aus am Rohrumfang 11 angeordneten Falten 12 besteht, die sich in Ebenen 13 erstrecken, die minde stens annähernd senkrecht zur Rohrachse 4 verlaufen.Fig. 3 shows an embodiment that can compensate for twisting as well as kinks and axial changes in length. s 'The flexible pipe connection according to FIGS. 1 and 2 exists mainly from the bellows 1, the folds 2 of which extend in planes 3 arranged in a star shape, which run at least approximately parallel to the pipe axis 4. The folds 2 are arranged on the pipe circumference 5. The bellows 1 is connected on one side to the pipe end 7 running out into the flange 6 on the other side with the support pipe 8 which continues into the flange 9. The support tube 8 dips into the bellows 1 so that it cannot buckle under the influence of the torsional forces. In the embodiment according to FIG. 3, the flexible pipe connection consists of the bellows 1 and another bellows 10, which consists of folds 12 arranged on the pipe circumference 11, which extend in planes 13 which are at least approximately perpendicular to the pipe axis 4.
