Description

Die Erfindung bezieht sich auf einen Übergangsschutz gemäß dem Gattungsbegriff des Patentanspruches 1.The invention relates to a transitional protection according to the preamble of claim 1.

Gattungsgemäße Doppelwellenbälge sind an sich bekannt. Es handelt sich um hochtechnisierte Einrichtungen, die eine gute Isolation der Übergangseinrichtungen gegen Schall, Temperatur und Druckwellen bieten. Sie haben außerdem eine gute Eigenstabilität, ohne die notwendigen Relativbewegungen zwischen zwei gelenkig miteinander verbundenen Schienenfahrzeugen unvertretbar zu behindern. Daß sie bisher noch nicht bzw. nicht in größerem Umfang zum Einsatz kommen, liegt einerseits am mangelnden Bedürfnis nach derart hochentwickelten Baugruppen, andererseits daran, daß ihr Anschluß an den Schienenfahrzeugen, insbesondere aber das Kuppeln zweier Doppelwellenbälge miteinander in der Mitte zwischen zwei gelenkig miteinander gekuppelten Schienenfahrzeugen als aufwendig und kompliziert erachtet wurde. Die als nicht gegeben erachtete Notwendigkeit solcher Einrichtungen in Verbindung mit der als schwierig und aufwendig erachteten Kupplung führten jedenfalls dazu, daß bisher keine praxisnahe, brauchbare Kuppelmöglichkeit gefunden wurde.Generic double shaft bellows are known per se. These are high-tech devices that offer good insulation of the transition devices against sound, temperature and pressure waves. They also have good inherent stability without unreasonably hindering the necessary relative movements between two articulated rail vehicles. That they have not yet been used, or have not been used to a large extent, is due on the one hand to the lack of need for such highly developed assemblies, and on the other hand to the fact that their connection to the rail vehicles, but in particular the coupling of two double-shaft bellows with one another in the middle between two articulated couplings Rail vehicles was considered to be complex and complicated. In any case, the necessity of such devices, which is not considered to be given, in connection with the coupling, which is considered to be difficult and complex, has meant that no practical, usable coupling option has so far been found.

Im einzelnen ist es bekannt, an jedem zweier miteinander zu kuppelnder Fahrzeuge mit Übergangsschutzeinrichtungen in der Form tunnelförmiger Faltenbälge mittels eines inneren Endrahmens eine Faltenbalghälfte zu befestigen, dem äußeren Ende jeder Faltenbalghälfte einen äußeren Endrahmen zuzuordnen und die äußeren Endrahmen der Faltenbalghälften bei miteinander gekuppelten Fahrzeugen mittels Zentrierzapfen und Aufnahmetaschen gegeneinander zu zentrieren (EP-A-0206583). Dem einen jedes der beiden zusammengehörenden äußeren Endrahmen sind im Bereich seines einen vertikalen Abschnitts vorspringende Zentrierzapfen, im Bereich seines anderen vertikalen Abschnitts entsprechende, zurückspringende Aufnahmetaschen zugeordnet und die Zuordnung von Taschen und Zapfen ist so gewählt, daß bei miteinander gekuppelten Fahrzeugen die Zentrierzapfen jedes Endrahmens in die Zentriertaschen des jeweils anderen Endrahmens haben eindringen können. Im einzelnen sind weiter Übergangsschutzeinrichtungen bekannt, bei denen zur Komforterhöhung zwei wellenförmige Faltenbälge konzentrisch ineinander angeordnet sind. Die Wellen des einen dieser beiden Bälge sind nach dem vom doppelten Faltenbalg umschlossenen Übergangsbereich hin offen, die Wellen des anderen Balges sind entsprechend nach außen hin offen, in jeder Wand des Balges liegen die Falten Rücken an Rücken und die beiden Wellenbälge sind fest miteinander verbunden. An beiden Enden ist jeder Balg mit einem eigenen Anschlußrahmen versehen oder die beiden Bälge können an jedem Ende mit einem gemeinsamen Anschlußrahmen versehen sein, ohne daß dies jedoch im einzelnen näher ausgeführt wäre (DE-A-3617325). Schließlich ist es auch bereits bekannt, dem Endrahmen am einen Ende einer Übergangsschutzeinrichtung für Schienenfahrzeuge Haken zuzuordnen, die mittels eines manuell zu bedienenden Gestänges zum Zusammenwirken mit Hakenaufnahmen zu bringen sind (EP-A-0054458).In particular, it is known to fasten a bellows half to each of two vehicles to be coupled together with transition protection devices in the form of tunnel-shaped bellows by means of an inner end frame, to assign an outer end frame to the outer end of each bellows half, and to center the outer end frames of the bellows halves in vehicles coupled to one another and centering receiving pockets against each other (EP-A-0206583). One of each of the two associated outer end frames is assigned centering pins projecting in the area of its one vertical section, corresponding recessed receiving pockets in the area of its other vertical section, and the assignment of pockets and pins is chosen such that the centering pins of each end frame in coupled vehicles the centering pockets of the other end frame were able to penetrate. In particular, transition protection devices are known in which two undulating bellows are arranged concentrically one inside the other to increase comfort. The waves of one of these two bellows are open towards the transition area enclosed by the double bellows, the waves of the other bellows are correspondingly open to the outside, the folds lie back to back in each wall of the bellows and the two bellows are firmly connected to each other. Each bellows is provided with its own connection frame at both ends, or the two bellows can be provided with a common connection frame at each end, but without this being detailed (DE-A-3617325). Finally, it is also already known to assign hooks to the end frame at one end of a transition protection device for rail vehicles, which hooks are to be brought into cooperation with hook receptacles by means of a manually operated linkage (EP-A-0054458).

Die Entwicklung von Hochgeschwindigkeitszügen mit gehobenem Komfort seit einer Reihe von Jahren läßt es geraten erscheinen, sich erneut mit dem Problem zu befassen, faltenbalgartige Übergangsschutzeinrichtungen komforterhöhend, bedienungsfreundlich und baulich besonders zweckmäßig auszubilden und es ist Aufgabe der Erfindung, eine gattungsgemäße Anordnung so auszubilden, daß Doppelwellenbälge zur Komforterhöhung angewendet werden können, daß die Hälften eines Doppelwellenbalges zwischen zwei Fahrzeugen einfach und zuverlässig miteinander gekuppelt werden können und die Mittel zum Verbinden der Doppelwellenbalghälften miteinander und mit ihren Fahrzeugen einfach und betriebssicher sowie einfach zu bedienen sind.The development of high-speed trains with increased comfort for a number of years makes it seem advisable to deal again with the problem of making bellows-type transition protection devices more convenient, user-friendly and structurally particularly useful, and it is the object of the invention to design a generic arrangement in such a way that double shaft bellows can be applied to increase comfort that the halves of a double-shaft bellows between two vehicles can be easily and reliably coupled and the means for connecting the double-shaft bellows halves with each other and with their vehicles are simple and reliable and easy to use.

Der Lösung dieser Aufgabe dienen die Merkmale des Kennzeichnungsteiles des Patentanspruches 1 in Verbindung mit einer gattungsgemäßen Übergangsschutzeinrichtung sowie, in weiterer Ausgestaltung, die Merkmale der Unteransprüche.The features of the characterizing part of claim 1 in conjunction with a generic transition protection device and, in a further embodiment, the features of the subclaims serve to achieve this object.

Eine erfindungsgemäße Übergangsschutzeinrichtung gibt mit dem Doppelwellenbalg die Möglichkeit eines von Witterungsunbilden und gegen Druckwellen weitestgehend geschützten Überwechselns zwischen zwei Fahrzeugen. Der Einfluß von Außengeräuschen kann minimiert werden. Der Platzbedarf für die Anschluß- und Verbindungsmittel ist gering, da diese aufgrund ihrer Ausbildung auf geringstem Raum untergebracht werden können. Der Arbeitsaufwand beim Kuppeln und Entkuppeln zweier Fahrzeuge ist schließlich trotz der Ausbildung des Balges als Doppelwellenbalg nicht größer als bei konventionellen Bälgen. Insoweit geht die Erfindung von der EP-A-0 206 583 als der Erfindung nächstkommendem Stand der Technik aus, der eine besonders zweckmäßige Umsetzung der Lehre der DE-A- 3 617 325 in die Praxis ermöglicht.With the double-wave bellows, a transition protection device according to the invention gives the possibility of changing between two vehicles, which is protected from the weather and largely protected against pressure waves. The influence of outside noise can be minimized. The space required for the connection and connection means is small, since these can be accommodated in the smallest space due to their design. The work involved in coupling and uncoupling two vehicles is ultimately not greater than that of conventional bellows, despite the bellows being designed as a double-shaft bellows. In this respect, the invention is based on EP-A-0 206 583 as the closest prior art, which enables the teaching of DE-A-3 617 325 to be implemented in a particularly expedient manner.

Zwei Wellenbälge 1 und 2 bilden zwei konzentrisch zueinander angeordnete, ringsum geschlossene Röhren mit etwa rechteckigen Querschnitten. Die Form des Doppelwellenbalges ist insbesondere aus Fig. 3 erkennbar. Ein innerer Wellenbalg 1 wird aus mehreren aufeinanderfolgenden und miteinander verbundenen Wellen mit etwa halbkreisförmigem Querschnitt, wobei die Halbkreise sich in parallelen Seitenwänden fortsetzen, gebildet. Das Material ist vorzugsweise mit Gummi oder dergleichen beschichtetes Gewebe. Entsprechend in Form und Material ist der äußere Wellenbalg 2. Die Rinnen des inneren Wellenbalges 1 sind zu einer nicht gezeichneten Übergangsbrücke zwischen zwei gelenkig miteinander gekuppelten Schienenfahrzeugen hin offen. Die Rinnen des äußeren Wellenbalges 2 sind nach außen hin offen, so daß innerer und äußerer Wellenbalg mit ihren Rinnenrücken einander zugekehrt sind. Die Rinnenenden des äußeren Wellenbalges 2 liegen im Bereich der Balgseitenwände etwa in den vertikalen Längsebenen, in denen sich die Fahrzeugseitenwände bei der Geradeausfahrt befinden. Ansonsten liegen die Rinnenenden des äußeren Wellenbalges etwa im Dachbereich bzw. im Kupplungsbereich beider Fahrzeuge. Der innere Wellenbalg ist in einem angemessenen, im wesentlichen gleichbleibenden Abstand hinter dem äußeren Wellenbalg angeordnet. Die hinteren Enden beider Wellenbälge sind an einem der beiden gelenkig miteinander gekuppelten Fahrzeuge befestigt. Die vorderen Enden der beiden Wellenbälge sind mit den entsprechenden vorderen Enden der Wellenbälge des zweiten der miteinander lösbar gelenkig gekuppelten Fahrzeuge lösbar und starr verbunden. Die Relativbewegungen zwischen beiden Fahrzeugen bewirken Verformungen der Bälge in sich bzw. die Bälge sind so in sich verformbar, daß Relativbewegungen der beiden Fahrzeuge zueinander nicht wesentlich beeinträchtigt werden.Two bellows 1 and 2 form two concentrically arranged, completely closed tubes with approximately rectangular cross sections. The shape of the double shaft bellows can be seen in particular from FIG. 3. An inner bellows 1 is formed from several successive and interconnected shafts with an approximately semicircular cross section, the semicircles continuing in parallel side walls. The material is preferably fabric coated with rubber or the like. Corresponding in shape and material is the outer bellows 2. The grooves of the inner bellows 1 are open to a transition bridge, not shown, between two articulated coupled rail vehicles. The gutters of the outer bellows 2 are open to the outside, so that the inner and outer bellows face each other with their channel back. The channel ends of the outer corrugated bellows 2 lie in the area of the bellows side walls approximately in the vertical longitudinal planes in which the vehicle side walls are located when driving straight ahead. Otherwise, the channel ends of the outer bellows are located approximately in the roof area or in the coupling area of both vehicles. The inner bellows is located at an appropriate, substantially constant distance behind the outer bellows. The rear ends of both bellows are attached to one of the two articulated vehicles. The front ends of the two bellows are detachably and rigidly connected to the corresponding front ends of the bellows of the second of the vehicles which are detachably coupled to one another. The relative movements between the two vehicles cause the bellows to deform themselves or the bellows are deformable in such a way that relative movements of the two vehicles with respect to one another are not significantly impaired.

Erfindungswesentlich ist nun, daß die beiden Bälge 1 und 2 an beiden Enden an je einem gemeinsamen Endrahmen 3 bzw. 4 befestigt sind. Jeder Endrahmen ist ein ringsumlaufendes Strangprofil mit hutförmigem Querschnitt. Jedes Hutprofil besteht aus einem U-förmigen Grundteil 3a bzw. 4a und relativ breiten Flanschen 3b, 3c bzw. 4b, 4c. Zwischen Grundteil und Flanschen sind schräg nach innen verlaufende Schrägflächen 3d, 3e bzw. 4d, 4e vorgesehen, so daß jedes Hutprofil im Anschluß an seine Flansche eine sich zunächst trichterförmig verjüngende Rinne bildet (Fig. 3, 5).It is essential to the invention that the two bellows 1 and 2 are attached at both ends to a common end frame 3 and 4, respectively. Each end frame is a continuous extruded profile with a hat-shaped cross-section. Each hat profile consists of a U-shaped base part 3a or 4a and relatively wide flanges 3b, 3c or 4b, 4c. Between the base part and flanges, inclined surfaces 3d, 3e or 4d, 4e, which run inwards, are provided, so that each hat profile forms an initially funnel-shaped groove following its flanges (FIGS. 3, 5).

An den beiden Flanschen 3b, 3c des inneren Strangprofiles 3 sind die beiden Wellenbälge 1, 2 durch Klemmprofile o.dgl. befestigt, und dieses Strangprofil weist Befestigungszapfen 5 auf, mit denen dieses innere- Strangprofil am einen der beiden miteinander gekuppelten Fahrzeuge zu befestigen ist, was im Einzelnen nicht näher erläutert werden muß.On the two flanges 3b, 3c of the inner extruded profile 3, the two bellows 1, 2 by means of clamping profiles or the like. attached, and this extruded profile has mounting pins 5, with which this inner extruded profile is to be attached to one of the two coupled vehicles, which need not be explained in detail.

Die Befestigung der beiden Bälge 1 und 2 an ihren äußeren Enden am äußeren Strangprofil 4 ergibt sich aus Fig. 2. Die einzelnen Rinnen jedes Wellenbalges 1 bzw. 2 sind durch Klemmprofile 6 zusammengehalten. Ein solches Klemmprofil 6a ist auch dem äußeren Rand der letzten, äußeren Rinne des dargestellten äußeren Wellenbalges 2 zugeordnet. Mit diesem Klemmprofil liegt der äußere Wellenbalg 2 mit seinem äußeren Ende auf dem freien Ende des äußeren Flansches des Strangprofiles 4 auf und über dieses Flanschende und das Klemmprofil 6a ist ein Klemmprofil 7 geschoben, das mittels eines in eine Nut 8 eingelegten Keders 9 gespannt wird. In entsprechender und deshalb nicht dargestellter Weise ist das äußere Ende des inneren Wellenbalges am inneren Flansch desselben Strangprofiles 4 befestigt.The attachment of the two bellows 1 and 2 at their outer ends to the outer extruded profile 4 is shown in FIG. 2. The individual channels of each bellows 1 and 2 are held together by clamping profiles 6. Such a clamping profile 6a is also assigned to the outer edge of the last, outer groove of the illustrated outer bellows 2. With this clamping profile, the outer bellows 2 rests with its outer end on the free end of the outer flange of the extruded profile 4 and a clamping profile 7 is pushed over this flange end and the clamping profile 6 a, which is tensioned by means of a welt 9 inserted into a groove 8. In a corresponding and therefore not shown manner, the outer end of the inner bellows is attached to the inner flange of the same extruded profile 4.

Dem Strangprofil sind an dem in Fig. 1 linken vertikalen Seitenteil pyramidenförmige Führungsbolzen 10 zugeordnet, wobei als ausreichende Zahl zwei solche Führungsbolzen auf die Länge der linken Seite des Strangprofiles verteilt sind. Als bevorzugte Ausführungsform ist eine vierflächige Pyramide gewählt.The extruded profile is assigned pyramid-shaped guide bolts 10 on the left vertical side part in FIG. 1, two such guide bolts being distributed over the length of the left side of the extruded profile as a sufficient number. A four-surface pyramid is selected as the preferred embodiment.

In entsprechender Anordnung und Form sind an dem in Fig. 1 rechten vertikalen Seitenteil des äußeren Endrahmens bzw. Strangprofiles 4 zwei hohlpyramidenförmige Trichter 11 angeordnet. Zum Kuppeln zweier Wellenbalgpaare an ihren äußeren Enden bzw. deren Endrahmen (Fig. 5) kommen die Führungsbolzen des einen Endrahmens mit den Aufnahmetrichtern des anderen Endrahmens in Eingriff, so daß die Endrahmen korrekt aufeinander ausgerichtet sind.In a corresponding arrangement and shape, two hollow pyramid-shaped funnels 11 are arranged on the right vertical side part of the outer end frame or extruded profile 4 in FIG. 1. For coupling two pairs of corrugated bellows at their outer ends or their end frames (FIG. 5), the guide bolts of one end frame come into engagement with the receiving funnels of the other end frame, so that the end frames are correctly aligned with one another.

Die Befestigung der Führungsbolzen und Aufnahmetrichter an dem Endrahmen ergibt sich insbesondere aus Fig. 2. Der als Beispiel dienende Führungsbolzen 10 ist auf einer Grundplatte 12 befestigt, die mit Schrauben 13 an den inneren Bereichen der Flansche 4b, 4c befestigt ist und die Profilrinne auf einer angemessenen Länge überbrückt.The fastening of the guide bolts and receiving funnel to the end frame results in particular from FIG. 2. The exemplary guide bolt 10 is fastened on a base plate 12, which is fastened with screws 13 to the inner regions of the flanges 4b, 4c and the profile channel on one bridged reasonable length.

Der Verbindung zweier in dieser Weise aufeinander ausgerichteter. äußerer Endrahmen 4, 4′ dienen Haken und Ösen, die wie die Führunqsbolzen und Aufnahmetrichter dem Endrahmen zugeordnet sind und wie diese ausreichend weit über den Endrahmen hinausstehen (Fig. 2, 3). Dem in Fig. 1 linken vertikalen Seitenteil des Endrahmens sind zwei vertikal verstellbare Haken 14 zugeordnet, an dem in Fig. 1 rechten Seitenteil des äußeren Endrahmens 4 sind in der gleichen Weise wie die Führungsbolzen und Aufnahmetrichter zwei entsprechende Ösen 15 befestigt. In ihrer einen Endstellung sind die Haken des einen Endrahmens in die Ösen des anderen Endrahmens lösbar gegeneinander fest. In ihrer anderen Endstellung sind die Haken aus den Ösen heraus getreten und die beiden Endrahmen können voneinander getrennt werden.The connection of two aligned in this way. Outer end frame 4, 4 'serve hooks and eyes which are assigned to the end frame like the guide bolts and receiving funnels and how these project sufficiently far beyond the end frame (Fig. 2, 3). 1 vertical side part of the end frame are assigned two vertically adjustable hooks 14, on the right side part of the outer end frame 4 in FIG. 1 two corresponding eyelets 15 are fastened in the same way as the guide bolts and receiving funnel. In one end position, the hooks of one end frame are releasably fixed to one another in the eyelets of the other end frame. In their other end position, the hooks have come out of the eyelets and the two end frames can be separated from one another.

Um gemeinsam verstellt werden zu können, sind die beiden Haken 14 an einer gemeinsamen Stange 16 befestigt, die in dem U-förmigen Abschnitt des Endrahmens geführt und vertikal verstellbar ist (Fig.6, 4). Zur Führung sind die vier Seiten der im Querschnitt viereckigen Stange 16 mit reibungs- und abriebsmindernden Streifen 17 belegt, von denen drei Streifen spielarm an den drei Seiten des U-förmigen Abschnittes 4a des Strangprofiles anliegen und der vierte Streifen an einer Fläche 18 anliegt, die im Verstellbereich der Stange an dem Strangprofil befestigt ist und in dieses eintaucht.In order to be able to be adjusted together, the two hooks 14 are fastened to a common rod 16 which is guided in the U-shaped section of the end frame and is vertically adjustable (FIGS. 6, 4). For guidance, the four sides of the rod 16, which is square in cross section, are covered with friction and abrasion-reducing strips 17, of which three strips bear with little play on the three sides of the U-shaped section 4a of the extruded profile and the fourth strip lies against a surface 18 which is attached to the extruded profile in the adjustment range of the rod and plunges into it.

Der vertikalen Verstellung der Stange 16 dient ein Arm 19, der an der Stange 16 befestigt ist und aus dem Strangprofil herausgeführt ist, in einem Bereich, in dem dieses nicht durch Befestigungsplatten bzw. Grundplatten 12 geschlossen ist. Dieser Arm 19 ist gelenkig mit einem Kniehebelmechanismus 20 verbunden, der mittels eines Handgriffes 21 geschwenkt werden kann und der in seine beiden Endstellungen durch eine Totpunktstellung hindurchgeschwenkt wird. Der Handgriff 21 ist durch einen Schlitz 22 im inneren Wellenbalg hindurch zugänglich. Der Schlitz ist mit einem Reißverschluß 23 zu verschließen, und ist mit einer Fahne 24 verdeckt, die aus dem Material der beiden Wellenbälge besteht und an ihrer einen Seite mit dem Ende des inneren Wellenbalges in der bereits beschriebenen Weise am äußeren Endrahmen befestigt ist (Fig. 2).The vertical adjustment of the rod 16 is served by an arm 19 which is fastened to the rod 16 and is led out of the extruded profile in an area in which it is not closed by fastening plates or base plates 12. This arm 19 is connected in an articulated manner to a toggle lever mechanism 20 which can be pivoted by means of a handle 21 and which is pivoted through its dead center position into its two end positions. The handle 21 is accessible through a slot 22 in the inner bellows. The slot is to be closed with a zipper 23 and is covered with a flag 24, which consists of the material of the two bellows and on one side with the end of the inner bellows is attached to the outer end frame in the manner already described (Fig. 2).

Nahe ihren unteren Enden sind die beiden vertikalen Seitenteile des äußeren Endrahmens 4 durch eine Traverse 25 gegeneinander ausgesteift. Diese Traverse ist so ausgebildet, daß sie auf einer Mittelpufferkupplung abgestützt werden kann, in der die beiden Fahrzeuge miteinander gekuppelt sind und die sich im Bereich unterhalb der Traversen der Endrahmen der Bälge beider Fahrzeuge und oberhalb deren unteren Böden befindet, die, wie gegebenenfalls auch das Dach, zu öffnen sind.Near their lower ends, the two vertical side parts of the outer end frame 4 are braced against one another by a cross member 25. This traverse is designed so that it can be supported on a central buffer coupling, in which the two vehicles are coupled to one another and which is located in the area below the traverses of the end frames of the bellows of both vehicles and above their lower floors, which, as the case may be, that Roof to be opened.

Insbesondere wenn es sich um Fahrzeuge handelt, die durch eine Haken- bzw. Spindelkupplung miteinander gekuppelt sind und bei denen eine entsprechende Abstützung der äußeren Endrahmen nicht möglich ist, können die äußeren Endrahmen 4 über seitliche Seile 26 an den inneren Endrahmen 3 aufgehängt werden. Die Seile greifen an den unteren Enden der äußeren Endrahmen 4 an und sind an den oberen Enden der inneren Endrahmen 3 eingehängt. Gegebenenfalls können in die Seile Spannfedern eingefügt sein.Particularly when it comes to vehicles that are coupled to one another by a hook or spindle coupling and in which a corresponding support of the outer end frame is not possible, the outer end frame 4 can be suspended from the inner end frame 3 via lateral ropes 26. The ropes engage the lower ends of the outer end frames 4 and are suspended from the upper ends of the inner end frames 3. If necessary, tension springs can be inserted into the ropes.

Die miteinander zu verbindenden äußeren Endrahmen 4, 4′ zweier miteinander gekuppelten Fahrzeuge (Fig. 5) können durch lippenförmige Dichtstreifen 27 gegeneinander abgedichtet sein. In einer ringsumlaufenden Nut 28 des äußeren Flansches 4b ist ein Dichtstreifen 27 eingelegt und dort verspannt. Zwei äußere Lippen des Dichtstreifen kommen mit Spannung auf den Lippen des Dichtstreifens des zweiten äußeren Endrahmens zur Auflage. Der Begrenzung des Mindestabstandes zwischen zwei äußeren Endrahmen dienen Distanzleisten 29.The outer end frame 4, 4 'to be connected to one another of two vehicles coupled to one another (FIG. 5) can be sealed against one another by lip-shaped sealing strips 27. In a circumferential groove 28 of the outer flange 4b, a sealing strip 27 is inserted and clamped there. Two outer lips of the sealing strip come to rest with tension on the lips of the sealing strip of the second outer end frame. Spacers 29 serve to limit the minimum distance between two outer end frames.

Die Erfindung ist erläutert an einem gattungsgemäßen Doppelwellenbalg, bei dem die Wellen des inneren Wellenbalges nach dem Übergang hin offen sind, während die Wellen des äußeren Wellenbalges nach außen hin offen sind. Es ist ohne weiteres zu ersehen, daß die Erfindung bei einem gattungsgemäßen Balg auch dann anwendbar ist, wenn die Wellen des inneren Wellenbalges nach außen hin, die Wellen des äußeren Wellenbalges nach dem Übergang hin offen sind.The invention is explained on a generic double-bellows, in which the waves of the inner bellows are open after the transition, while the waves of the outer bellows are open to the outside. It is straightforward too see that the invention is applicable to a generic bellows even if the waves of the inner bellows outwards, the waves of the outer bellows are open after the transition.
