Description

Die vorliegende Erfindung betrifft ein Verbindungselement für eine schwingungs- und schalldämpfende Verbindung zweier Bauteile, insbesondere zwischen einer Wagenkastenrohbaustruktur eines Schienenfahrzeugs und einem Einrichtungsteil des Schienenfahrzeugs, mit einer sich in einer Längsrichtung erstreckenden äußeren Halteschiene, die einen sich in Längsrichtung erstreckenden Grundsteg und zwei vom Grundsteg ausgehende, voneinander beabstandete, sich in Längsrichtung erstreckende Seitenstege aufweist, die insbesondere am vom Grundsteg entfernten Ende in einem Frontabschnitt aufeinander zulaufen, wobei zwischen den beiden Seitenstegen ein in Längsrichtung verlaufender Spalt ausgebildet ist, derart, dass die Halteschiene einen C-förmigen Querschnitt aufweist, mit einem innerhalb der Halteschiene gehaltenen plattenförmigen Element, das mindestens eine Bohrung aufweist, und mit einem gummielastischen Dämpfungsmaterial, das zumindest abschnittsweise zwischen Halteschiene und plattenförmigem Element angeordnet ist und in das das plattenförmige Element zumindest mit zwei seiner Kanten eingebettet ist, derart, dass das plattenförmige Element die Halteschiene nicht berührt, wobei das gummielastische Dämpfungsmaterial mit der Halteschiene und dem plattenförmigen Element fest verbunden ist. Ferner betrifft die Erfindung eine Verbindungsanordnung mit einem solchen Verbindungselement sowie ein Schienenfahrzeug mit einer entsprechenden Verbindungsanordnung.The present invention relates to a connection element for a vibration and sound-damping connection of two components, in particular between a car body shell structure of a rail vehicle and a device part of the rail vehicle, having a longitudinally extending outer support rail having a longitudinally extending web and two outgoing from the base web , spaced apart, extending in the longitudinal direction of the side webs, which converge in particular at the distal end of the web in a front portion to each other, wherein between the two side bars a longitudinally extending gap is formed, such that the support rail has a C-shaped cross-section, with a plate-shaped element held within the retaining rail, which has at least one bore, and with a rubber-elastic damping material, the at least partially between support rail and plates is arranged shaped element and in which the plate-shaped element is embedded at least with two of its edges, such that the plate-shaped element does not touch the retaining rail, wherein the rubber-elastic damping material is fixedly connected to the retaining rail and the plate-shaped element. Furthermore, the invention relates to a connection arrangement with such a connecting element and a rail vehicle with a corresponding connection arrangement.

Verbindungselement und Verbindungsanordnungen der zuvor beschriebenen Art dienen bei Schienenfahrzeugen zur Verbindung der Wagenkastenrohbaustruktur mit Einrichtungsteilen, beispielsweise Seiten- und Deckenverkleidungselementen, Fußbodenelementen etc. Dabei weisen die Verbindungselemente in der Regel zwei Metallprofile auf, die sich selbst nicht untereinander berühren, aber über eine schwingungs- und schalldämpfende Masse miteinander verbunden sind. Eines der beiden das Verbindungselement bildenden Metallprofile dient zur Verbindung mit der Wagenkastenrohbaustruktur, beispielsweise über Schrauben und Nutensteine. Das andere Metallprofil, welches von dem ersten Metallprofil durch die genannte schwingungs- und schalldämpfende Masse entkoppelt ist, dient zur Aufnahme der Nutzlast, wird also beispielsweise mit Verkleidungsteilen der Innenverkleidung verbunden.Connecting element and connection arrangements of the type described above are used in rail vehicles for connecting the Wagenkastenrohbaustruktur with equipment parts, such as side and ceiling trim elements, floor elements, etc. In this case, the fasteners usually have two metal profiles that do not touch each other, but on a vibration and sound-absorbing mass are interconnected. One of the two metal profiles forming the connecting element serves for connection to the car body shell structure, for example via screws and sliding blocks. The other metal profile, which is decoupled from the first metal profile by said vibration and sound-damping mass, serves to accommodate the payload, so it is connected, for example, with trim parts of the inner lining.

Auf diese Weise soll den erhöhten Anforderungen an die Schwingungs- und Schalldämpfung bei der Konstruktion von Schienenfahrzeugen insbesondere für den Personenverkehr Genüge getan werden und dadurch der Komfort für die Passagiere erhöht werden.In this way, the increased demands on the vibration and sound attenuation in the construction of rail vehicles, in particular for passenger transport will be satisfied and thereby increases the comfort for the passengers.

Aus dem Stand der Technik sind verschiedene Arten von zuvor beschriebenen Verbindungselementen, auch Entkopplungselemente genannt, bekannt. So offenbart die EP 1 112 206 B1 ein Verbindungselement, bei dem es sich bei dem ersten Metallprofil um eine C-förmige Halteschiene, auch C-Schiene genannt, und bei dem zweiten Metallprofil um ein Hutprofil handelt. C-Schiene und Hutprofil erstrecken sich in einer Längsrichtung, wobei das Hutprofil im Innern der C-Schiene in ein gummielastisches Dämpfungsmaterial eingebettet ist. Die äußere C-Schiene ist Bestandteil der Wagenkastenrohbaustruktur, das innenliegende Hutprofil dient zur Anbindung von Teilen der Innenverkleidung des Wagenkastens und weist zu diesem Zweck mindestens eine Durchgangs- oder Gewindebohrung auf. Nachteil dieser Anordnung ist, dass die aufnehmende C-Schiene einen Innenraum mit etwa sechseckigem Querschnitt umgreift und nicht für die Aufnahme von im Schienenfahrzeugbau üblichen Nutensteinen zur Befestigung anderer Bauteile geeignet ist. Da für die Nutensteine C-Tragschienen vorhanden sein müssen, die einen Innenraum mit etwa rechteckigem Querschnitt umgreifen, muss ein Wagenkastenrohbau, der für beide Befestigungsarten ausgelegt ist, beide C-Schienen-Arten aufweisen. Dies schränkt die konstruktive Freiheit für den Innenausbau nicht unwesentlich ein. Ein weiterer Nachteil ist, dass die aufnehmende C-Schiene entlang ihrer Längserstreckung Unterbrechungen aufweisen muss, damit die anderen Bestandteile des Verbindungselements in sie eingebracht und durch Längsverschiebung an den gewünschten Verbindungsort verbracht werden können.Various types of connecting elements described above, also called decoupling elements, are known from the prior art. So revealed the EP 1 112 206 B1 a connecting element in which the first metal profile is a C-shaped retaining rail, also called a C-rail, and the second metal profile is a hat profile. C-rail and hat profile extend in a longitudinal direction, wherein the hat profile is embedded in the interior of the C-rail in a rubber-elastic damping material. The outer C-rail is part of the Wagenkastenrohbaustruktur, the inner hat profile is used to connect parts of the inner lining of the car body and has for this purpose at least one passage or threaded hole. Disadvantage of this arrangement is that the female C-rail surrounds an interior with approximately hexagonal cross-section and is not suitable for the inclusion of usual in rail vehicle nuts for fixing other components. As for the sliding blocks C-rails must be present, embrace an interior with approximately rectangular cross-section, a car body shell, which is designed for both types of attachment, both C-rail types have. This restricts the constructive freedom for the interior not insignificant. A further disadvantage is that the receiving C-rail must have interruptions along its longitudinal extent, so that the other components of the connecting element can be introduced into it and moved by longitudinal displacement to the desired connection location.

Einen anderen Aufbau eines Verbindungselements offenbart die CN 201338611 Y . Hier ist ein Hutprofil über zwei gummielastische Dämpfungselemente in einen vom Wagenkastenrohbau unabhängigen C-förmigen Schienenabschnitt, dessen Schlitzöffnung vom Wagenkastenrohbau wegweist, eingebettet. Um am Wagenkastenrohbau angeschraubt werden zu können, weist der C-förmige Schienenabschnitt mindestens eine Durchgangsbohrung zur Aufnahme eines Gewindebolzens auf. Ein solches Verbindungelement kann direkt auf einer Innenfläche des Wagenkastenrohbaus befestigt werden. Es kann aber auch über schienenfahrzeugübliche C-Tragschienen, die Bestandteil des Wagenkastenrohbaus sind, dessen Innenfläche überragen und übliche Nutensteine aufnehmen, am Wagenkastenrohbau befestigt sein.Another structure of a connecting element discloses the CN 201338611 Y , Here is a hat profile over two rubber-elastic damping elements in a car body shell independent C-shaped rail section, the slot opening points away from the car body shell embedded. In order to be screwed to the car body shell, the C-shaped rail section has at least one through hole for receiving a threaded bolt. Such a connection element can be mounted directly on an inner surface of the Wagenkastenrohbaus. But it can also be rail-standard C-rails, the component of the car body shell, the inner surface of which protrude and receive usual sliding blocks, be attached to the car body shell.

Im letztgenannten Fall benötigt diese Anordnung jedoch eine relativ große Bauhöhe, was eine möglichst rohbauwandnahe Befestigung von Einrichtungsteilen erschwert oder unmöglich macht.In the latter case, however, this arrangement requires a relatively large height, which makes it difficult or impossible as far as possible close to the wall construction of fixture parts.

Aus der gattungsbildenden EP 0 576 394 A1 ist ein Verbindungselement bekannt, bei dem eines der beiden Metallprofile ein U-Profil und das andere ein Hutprofil ist, das von dem U-Profil umgriffen wird. Zwei dämpfende gummieleastische Elemente verbinden die Außenschenkel des U-Profils, die zum Wagenkastenrohbau gerichtet sind, und die dazu parallel verlaufenden Schenkel des im Inneren des U-Profils gelegenen Hutprofils. Hier dient das innenliegende Hutprofil zur Befestigung an der Wagenkastenrohbaustruktur, das äußere U-Profil zur Verbindung mit Fußbodenelementen.From the generic EP 0 576 394 A1 is a connecting element is known in which one of the two metal profiles is a U-profile and the other is a hat profile, which is encompassed by the U-profile. Two damping rubber-elastic elements connect the outer legs of the U-profile, which are directed to the car body shell, and the parallel legs of the located inside the U-profile hat profile. Here, the inner hat profile is used for attachment to the Wagenkastenrohbaustruktur, the outer U-profile for connection with floor elements.

Diese Anordnung ist gut geeignet, in Richtung des Wagenkastenrohbaus auf sie wirkende Druckkräfte aufzunehmen; von Nachteil ist jedoch, dass sie keine oder nur geringe entgegengesetzt wirkende Zugkräfte aufnehmen kann, da dann die elastischen Elemente auf Scherung und/oder Zug beansprucht werden und zu versagen drohen.This arrangement is well suited to take in the direction of the Wagenkastenrohbaus acting on them compressive forces; the disadvantage, however, is that they can absorb no or only small oppositely acting tensile forces, since then the elastic elements are subjected to shear and / or train and threaten to fail.

Gemäß einem weiteren Stand der Technik der Lokomotivbau Elektrotechnische Werke Hans Beimler Hennigsdorf (LEW) wurden in Schienenfahrzeugen der Zugreihe 612 Verbindungselemente zur Befestigung von Tischen an der Wagenkastenrohbaustruktur mit dem folgenden Aufbau verwendet: zur Befestigung an der Wagenkastenrohbaustruktur dient eine C-förmige Halteschiene, wobei das in Längsrichtung verlaufende C-Profil einen Grundsteg und zwei davon ausgehende Seitenstege mit nach innen umgebogenen Frontabschnitten, zwischen denen ein Spalt ausgebildet ist, aufweisen. Im Innern der C-förmigen Halteschiene sind in Längsrichtung hintereinander und zueinander fluchtend zwei plattenförmige Elemente mit verdickten Seitenkanten angeordnet, die aufgrund ihres Querschnitts auch Knochen genannt werden. Mit den verdickten Seitenkanten sind die Knochen in ein gummielastisches Dämpfungsmaterial, nämlich vulkanisierten Gummi, eingebettet. Die Knochen ragen in Längsrichtung jeweils über einen Teil ihrer Länge über die äußere Begrenzung der C-förmigen Halteschiene hinaus. Die beiden im Innern der C-förmigen Halteschiene angeordneten, einander zugewandten Enden der beiden Knochen sind dabei voneinander beabstandet, so dass zwischen den Knochen eine Aussparung gebildet wird. Quer zur Längsrichtung mit der Aussparung fluchtend ist im Grundsteg der C-förmigen Halteschiene eine Gewindebohrung angeordnet, über die mittels eines korrespondierenden Befestigungselements das Verbindungselement mit der Nutzlast, nämlich dem Tisch, verbunden werden kann. Die beiden aus der äußeren Begrenzung der C-förmigen Halteschiene in Längsrichtung hervorstehenden Abschnitte der plattenförmigen Elemente sind jeweils mit einer Bohrung zur Aufnahme einer Befestigungsschraube versehen, die mit einem Nutenstein verschraubt ist, der in eine C-Schiene der Wagenkastenrohbaustruktur eingesetzt wird. Die beiden in Längsrichtung hervorstehenden Abschnitte der Knochen dienen damit zur Befestigung an der Wagenkastenrohbaustruktur. Problematisch bei diesem Stand der Technik ist jedoch, dass die Knochen in der Nähe der Bohrung im Laufe der Zeit durch viele Lastwechsel einreißen können.According to another state of the art locomotive engineering works Hans Beimler Hennigsdorf (LEW) were used in rail vehicles of the train 612 fasteners for attachment of tables to the car body shell structure with the following structure: for attachment to the car body shell structure is a C-shaped support rail, wherein the longitudinal C-profile has a base web and two side webs extending therefrom with inwardly bent front portions, between which a gap is formed. Inside the C-shaped support rail two plate-shaped elements are arranged with thickened side edges in the longitudinal direction one behind the other and aligned with each other, which are also called bone due to their cross section. With the thickened side edges, the bones are embedded in a rubber-elastic damping material, namely vulcanized rubber. The bones protrude in the longitudinal direction over part of their length beyond the outer boundary of the C-shaped support rail out. The two arranged in the interior of the C-shaped support rail, facing each other ends of the two bones are spaced apart, so that between the bones a recess is formed. Aligned transversely to the longitudinal direction with the recess, a threaded bore is arranged in the base web of the C-shaped retaining rail, via which the connecting element can be connected to the payload, namely the table, by means of a corresponding fastening element. The two longitudinally projecting from the outer boundary of the C-shaped support rail portions of the plate-shaped elements are each provided with a bore for receiving a fastening screw which is bolted to a sliding block, which is inserted into a C-rail of the Wagenkastenrohbaustruktur. The two longitudinally projecting portions of the bone thus serve for attachment to the Wagenkastenrohbausstruktur. The problem with this prior art, however, is that the bones in the vicinity of the bore can tear over many load changes over time.

Aus einem internen Stand der Technik ist ferner ein Verbindungselement mit einem ähnlichen Aufbau wie das Verbindungselement der LEW bekannt, wobei jedoch statt zwei separater Knochen ein einzelner durchgehender Knochen in der C-förmigen Halteschiene in Längsrichtung verläuft. Dabei ist die Länge des durchgehenden Knochens so bemessen, dass dieser in Längsrichtung zu beiden Seiten über die äußere Begrenzung der C-förmigen Halteschiene herausragt und dadurch die beiden Befestigungsabschnitte zur Verbindung mit der Wagenkastenrohbaustruktur ausbildet. Auch bei diesem Verbindungselement besteht allerdings das Risiko, dass es im Laufe der Zeit im Bereich der Befestigungsabschnitte des Knochens zu einer Rissbildung kommt.From an internal prior art, a connecting element with a similar structure as the connecting element of LEW is also known, but instead of two separate bones, a single continuous bone in the C-shaped support rail extends in the longitudinal direction. In this case, the length of the continuous bone is dimensioned so that it protrudes in the longitudinal direction on both sides beyond the outer boundary of the C-shaped support rail and thereby forms the two attachment portions for connection to the Wagenkastenrohbaustruktur. However, even with this connecting element, there is the risk that cracking will occur over time in the region of the fastening sections of the bone.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Verbindungselement für eine schwingungs- und schalldämpfende Verbindung zweier Bauteile zu schaffen, das eine hohe Lebensdauer hat.It is therefore the object of the present invention to provide a connecting element for a vibration and sound-damping connection of two components, which has a long service life.

Die zuvor hergeleitete und aufgezeigte Aufgabe wird gemäß einer ersten Lehre der vorliegenden Erfindung gelöst durch ein Verbindungselement für eine schwingungs- und schalldämpfende Verbindung zweier Bauteile, insbesondere zwischen einer Wagenkastenrohbaustruktur eines Schienenfahrzeugs oder anderen Fahrzeugs und einem Einrichtungsteil des Fahrzeugs, mit einer sich in einer Längsrichtung (Profilverlaufsrichtung) erstreckenden Halteschiene, die einen sich in Längsrichtung erstreckenden Grundsteg und zwei vom Grundsteg ausgehende, voneinander beabstandete, sich in Längsrichtung erstreckende Seitenstege aufweist, die insbesondere am vom Grundsteg entfernten Ende in einem Frontabschnitt aufeinander zulaufen, wobei zwischen beiden Seitenstegen, insbesondere zwischen den beiden Frontabschnitten, ein in Längsrichtung verlaufender Spalt ausgebildet ist, derart, dass die Halteschiene einen C-förmigen Querschnitt aufweist, wobei der Spalt vorzugsweise eine Breite aufweist, die größer als die Breite einer C-Tragschiene der Wagenkastenrohbaustruktur ist, wobei in dem Grundsteg insbesondere mindestens eine Bohrung, vorzugsweise eine Gewindebohrung, vorgesehen ist, die zur Montage des Einrichtungsteils, das heißt der Nutzlast, dient, mit einem innerhalb der Halteschiene gehaltenen plattenförmigen Element, das sich vorzugsweise in einer Ebene erstreckt, die insbesondere parallel zum Grundsteg verläuft, und das mindestens eine Bohrung aufweist, die zur Anbringung insbesondere mittels Nutensteinen in der C-Tragschiene der Wagenkastenrohbaustruktur dient, wobei die mindestens eine Bohrung in dem plattenförmigen Element, bezogen auf die Längsrichtung, innerhalb der äußeren Begrenzung der Halteschiene liegt, und mit einem gummielastischen Dämpfungsmaterial, insbesondere Gummi oder gummiähnlichen Elastomermaterial, das zumindest abschnittsweise zwischen Halteschiene und plattenförmigem Element angeordnet ist und in das das plattenförmige Element zumindest mit zwei seiner Kanten, insbesondere der in Längsrichtung verlaufenden Kanten, eingebettet ist, derart, dass das plattenförmige Element die Halteschiene nicht berührt, wobei das gummielastische Dämpfungsmaterial mit der Halteschiene und dem plattenförmigen Element fest verbunden ist, insbesondere durch Vulkanisieren des Dämpfungsmaterials (nach dem Zusammenbringen bzw. -fügen von Halteschiene, Dämpfungsmaterial und plattenförmigem Element) oder durch Verkleben.The previously derived and indicated object is achieved according to a first teaching of the present invention by a connecting element for a vibration and sound-damping connection of two components, in particular between a car body shell structure of a rail vehicle or other vehicle and a device part of the vehicle, in a longitudinal direction ( Profile course direction) extending retaining rail, which has a longitudinally extending Base web and two emanating from the main web, spaced apart, extending in the longitudinal direction of side webs, in particular at the remote end of the web in a front portion converge, between both side webs, in particular between the two front portions, a longitudinally extending gap is formed, such in that the retaining rail has a C-shaped cross-section, wherein the gap preferably has a width which is greater than the width of a C-mounting rail of the vehicle body shell structure, wherein in the base web in particular at least one bore, preferably a threaded bore, is provided, which Assembly of the device part, that is the payload, is used, with a held within the support rail plate-shaped element, which preferably extends in a plane which is in particular parallel to the base web, and which has at least one bore insbesonde for mounting re by means of sliding blocks in the C-rail of Wagenkastenrohbaustruktur, wherein the at least one bore in the plate-shaped element, based on the longitudinal direction, within the outer boundary of the support rail, and with a rubber elastic damping material, in particular rubber or rubber-like elastomeric material, at least in sections between the support rail and plate-shaped element is arranged and in which the plate-shaped element with at least two of its edges, in particular the longitudinal edges, embedded, such that the plate-shaped element does not touch the retaining rail, wherein the rubber-elastic damping material with the support rail and the plate-shaped Element is firmly connected, in particular by vulcanizing the damping material (after the Matching or joining of retaining rail, damping material and plate-shaped element) or by gluing.

Die Bohrung in dem plattenförmigen Element liegt also in einem Abschnitt des plattenförmigen Elements, der in Längsrichtung nicht über die Enden der insbesondere C-förmigen Halteschiene, das heißt über ihre äußere Begrenzung in Längsrichtung, hinausragt. Dadurch entstehen, wenn Kräfte zwischen der Halteschiene und dem plattenförmigen Element übertragen werden, keine Momente um eine zur Längsrichtung senkrechte Achse, und zwar speziell um eine zu der Ebene, in der der Grundsteg verläuft, parallele Achse. Risse und Brüche im plattenförmigen Element, insbesondere im Bereich der Bohrung, werden dadurch zuverlässig verhindert. Die Lebensdauer des erfindungsgemäßen Verbindungselements wird dadurch deutlich erhöht.The bore in the plate-shaped element thus lies in a portion of the plate-shaped element, which does not protrude in the longitudinal direction over the ends of the particular C-shaped support rail, that is, over its outer boundary in the longitudinal direction. As a result, when forces are transmitted between the support rail and the plate-shaped element, there are no moments about an axis perpendicular to the longitudinal direction, specifically about an axis parallel to the plane in which the base rail passes. Cracks and breaks in the plate-shaped element, in particular in the region of the bore, are thereby reliably prevented. The life of the connecting element according to the invention is thereby significantly increased.

Gemäß einer Ausgestaltung des erfindungsgemäßen Verbindungselements weist das plattenförmige Element, damit dieses beispielsweise auf einer C-Tragschiene der Wagenkastenrohbaustruktur angebracht werden kann, mindestens zwei Bohrungen auf, die in Längsrichtung voneinander beabstandet sind und die beide, bezogen auf die Längsrichtung, innerhalb der äußeren Begrenzung der Halteschiene liegen. Die Bohrungen liegen also beide, oder wenn mehr als zwei Bohrungen im plattenförmigen Element zu dessen Anbringung beispielsweise an der Wagenkastenrohbaustruktur vorgesehen sind, liegen also alle Bohrungen in einem Abschnitt des plattenförmigen Elements, der in Längsrichtung nicht über die Enden der Halteschiene hinausragen.According to one embodiment of the connecting element according to the invention, the plate-shaped element, so that it can be mounted for example on a C-mounting rail of the Wagenkastenrohbaustruktur, at least two holes which are spaced apart in the longitudinal direction and both, based on the longitudinal direction, within the outer boundary of Retaining rail lie. The bores are thus both, or if more than two holes are provided in the plate-shaped element for attachment thereof, for example to the Wagenkastenrohbaustruktur, so all holes in a portion of the plate-shaped element, which do not protrude in the longitudinal direction over the ends of the support rail.

Mit dem erfindungsgemäßen Verbindungselement lassen sich ohne weiteres Einrichtungsteile wie Sitze, Tische, Versorgungskanäle, Gepäckablagen, Decken- und Seitenverkleidungen oder Fußbodenelemente mit der Wagenkastenrohbaustruktur schwingungs- und schalldämpfend verbinden, wobei das Verbindungselement nur eine geringe Bauhöhe beansprucht.With the connecting element according to the invention can easily parts such as seats, tables, supply channels, luggage racks, ceiling and side panels or floor elements with the Wagenkastenrohbaustruktur vibration and sound absorbing connect, the fastener claimed only a small height.

Gemäß einer weiteren Ausgestaltung des erfindungsgemäßen Verbindungselements ragt das gesamte plattenförmige Element in Längsrichtung nicht über die äußere Begrenzung der Halteschiene hinaus. Auf diese Weise wird ein kompaktes Verbindungselement geschaffen, das Schwingungen optimal vermeidet. Insbesondere ragt das plattenförmige Element auch quer zur Längsrichtung nicht über die äußere Begrenzung der Halteschiene hinaus, was die Kompaktheit noch weiter erhöht.According to a further embodiment of the connecting element according to the invention, the entire plate-shaped element does not protrude in the longitudinal direction beyond the outer boundary of the retaining rail. In this way, a compact connection element is created, which optimally avoids vibrations. In particular, the plate-shaped element also does not protrude transversely to the longitudinal direction beyond the outer boundary of the retaining rail, which further increases the compactness.

Gemäß noch einer Ausgestaltung des erfindungsgemäßen Verbindungselements werden unnötige Vibrationen auch dadurch verhindert und wird das Schwingungsverhalten noch weiter dadurch optimiert, dass das plattenförmige Element in Längsrichtung über seine gesamte Länge mit seinen zwei Kanten in das gummielastische Dämpfungsmaterial eingebettet ist. Das plattenförmige Element, welches wie gesagt insbesondere parallel zum Grundsteg verläuft, weist vorzugsweise zwei verdickte Seitenkanten, die in Längsrichtung verlaufen, auf. Diese verdickten Seitenkanten dienen bevorzugt zur Einbettung und Verankerung in dem gummielastischen Dämpfungsmaterial, insbesondere nach einer Vulkanisierung des Dämpfungsmaterials. Zwischen den in Längsrichtung verlaufenden Seitenkanten, insbesondere zwischen den verdickten Seitenkanten, ist das plattenförmige Element vorzugsweise plan und hat eine gleichmäßige Dicke.According to yet another embodiment of the connecting element according to the invention unnecessary vibrations are also prevented and the vibration behavior is further optimized by the fact that the plate-shaped element is embedded in the longitudinal direction over its entire length with its two edges in the rubber-elastic damping material. The plate-shaped element, which, as stated, runs in particular parallel to the base web, preferably has two thickened side edges extending in the longitudinal direction. These thickened side edges are preferably used for embedding and anchoring in the rubber-elastic damping material, in particular after vulcanization of the damping material. Between the longitudinal side edges, in particular between the Thickened side edges, the plate-shaped element is preferably flat and has a uniform thickness.

Gemäß noch einer weiteren Ausgestaltung des erfindungsgemäßen Verbindungselements liegt in dem Fall, dass das plattenförmige Element zur Montage des Verbindungselements an dem jeweiligen Bauteil mindestens zwei Bohrungen aufweist, bezogen auf die Längsrichtung, die mindestens eine Bohrung in der Halteschiene zwischen den Bohrungen in dem plattenförmigen Element. Insbesondere liegen alle Bohrungsachsen in Längsrichtung hintereinander, verlaufen also alle in derselben Ebene. Ein solcher Aufbau unterstützt einerseits eine kompakte Bauweise des Verbindungselements, führt andererseits aber auch zu einem optimalen Kräfteverlauf innerhalb des Verbindungselements.According to yet another embodiment of the connecting element according to the invention is in the case that the plate-shaped element for mounting the connecting element on the respective component has at least two holes, relative to the longitudinal direction, the at least one bore in the retaining rail between the holes in the plate-shaped element. In particular, all bore axes lie one behind the other in the longitudinal direction, ie they all run in the same plane. Such a construction on the one hand supports a compact design of the connecting element, but on the other hand also leads to an optimal flow of forces within the connecting element.

Gemäß wiederum einer weiteren Ausgestaltung des erfindungsgemäßen Verbindungselements ist in einer Richtung quer zur Längsrichtung koaxial zu der mindestens einen im plattenförmigen Element vorgesehenen Bohrung jeweils eine Ausnehmung, insbesondere auch eine Bohrung, im Grundsteg der Halteschiene vorgesehen, deren Querschnitt insbesondere größer als der Querschnitt der mindestens einen im plattenförmigen Element vorgesehenen Bohrung ist. Handelt es sich bei der Ausnehmung ebenfalls um eine Bohrung, so kann auch vorgesehen sein, dass der Durchmesser der Bohrung größer als der Durchmesser der mindestens einen im plattenförmigen Element vorgesehenen Bohrung ist. Eine solche Ausnehmung im Grundsteg ermöglicht, eine durch das plattenförmige Element geführte Schraube, die auf der Seite des Spaltes der Halteschiene beispielsweise über einen Nutenstein in einer C-Tragschiene der Wagenkastenrohbaustruktur verankert ist, von der Grundstegseite der Halteschiene aus zu betätigen. Dadurch ist es nicht mehr erforderlich, dass das plattenförmige Element mit einem Abschnitt, in dem eine Bohrung vorgesehen ist, in Längsrichtung über die äußere Begrenzung der Halteschiene hinausragt. Auf diese Weise ist die Schraube auch durch den Grundsteg der insbesondere C-förmigen Halteschiene zugänglich.According to yet another embodiment of the connecting element according to the invention is provided in a direction transverse to the longitudinal direction coaxially to the at least one provided in the plate-shaped member hole in each case a recess, in particular a hole in the base web of the retaining rail, the cross section in particular larger than the cross section of the at least one is provided in the plate-shaped element hole. If the recess is also a bore, it may also be provided that the diameter of the bore is greater than the diameter of the at least one bore provided in the plate-shaped element. Such a recess in the base web allows guided by the plate-shaped element screw which is anchored on the side of the gap of the retaining rail, for example via a sliding block in a C-mounting rail of the Wagenkastenrohbaustruktur of from the base web side of the retaining rail. As a result, it is no longer necessary that the plate-shaped element projects with a portion in which a bore is provided, in the longitudinal direction beyond the outer boundary of the retaining rail. In this way, the screw is also accessible through the base of the particular C-shaped support rail.

Bevorzugt liegen die mindestens eine Bohrung und die Ausnehmung(en) in einem verdickten Abschnitt des Grundstegs der insbesondere C-förmigen Halteschiene, wobei sich der verdickte Abschnitt insbesondere, bezogen auf die Längsrichtung, über die gesamte Länge der Halteschiene erstreckt. Ein solcher verdickter Abschnitt erhöht die Stabilität des Verbindungselements, insbesondere im Bereich der Bohrung und Ausnehmung(en).Preferably, the at least one bore and the recess (s) are in a thickened portion of the base web of the particular C-shaped support rail, wherein the thickened portion extends in particular, based on the longitudinal direction over the entire length of the support rail. Such a thickened section increases the stability of the connecting element, in particular in the area of the bore and recess (s).

Insbesondere liegen die Mittelachsen der mindestens einen Bohrung im Grundsteg und der Ausnehmung(en) im Grundsteg in Längsrichtung hintereinander, also in einer Ebene.In particular, the center axes of the at least one bore in the base web and the recess (s) in the base web lie one behind the other in the longitudinal direction, ie in one plane.

Gemäß noch einer weiteren Ausgestaltung des Verbindungselements ist in einer Richtung quer zu seiner Längsrichtung koaxial zu der mindestens einen in der Halteschiene vorgesehenen Bohrung jeweils eine Ausnehmung, insbesondere Bohrung, im plattenförmigen Element vorgesehen, deren Querschnitt insbesondere größer als der Querschnitt der mindestens einen in der Halteschiene vorgesehenen Bohrung ist.According to yet another embodiment of the connecting element is provided in a direction transverse to its longitudinal direction coaxially to the at least one hole provided in the holding rail in each case a recess, in particular bore, in the plate-shaped element whose cross-section in particular larger than the cross section of at least one in the support rail provided hole is.

Die Mittelachsen der mindestens einen im plattenförmigen Element vorgesehenen Bohrung, insbesondere der mindestens zwei Bohrungen, und die der im plattenförmigen Element vorgesehenen Ausnehmung liegen vorzugsweise in Längsrichtung hintereinander, also alle in einer Ebene.The central axes of the at least one provided in the plate-shaped element bore, in particular the at least two holes, and the recess provided in the plate-shaped element are preferably in the longitudinal direction one behind the other, so all in one plane.

Die im plattenförmigen Element vorgesehenen Bohrungen und Ausnehmungen sind bevorzugt in einem Abschnitt des plattenförmigen Elements angeordnet, der quer zur Längsrichtung zwischen den in Längsrichtung verlaufenden verdickten Seitenkanten liegt. Dieser Abschnitt erstreckt sich vorzugsweise auch über die gesamte Länge des plattenförmigen Elements.The holes and recesses provided in the plate-shaped element are preferably arranged in a section of the plate-shaped element which lies transversely to the longitudinal direction between the longitudinally thickened side edges. This section preferably also extends over the entire length of the plate-shaped element.

Die Aufgabe wird ferner gemäß einer zweiten Lehre der vorliegenden Erfindung gelöst durch eine Verbindungsanordnung mit einem Verbindungselement der zuvor definierten Art, mit einem ersten Bauteil, insbesondere einer Wagenkastenrohbaustruktur eines Schienenfahrzeugs oder anderen Fahrzeugs, und mit einem zweiten Bauteil, insbesondere einem Einrichtungsteil des Fahrzeugs, wobei die Spaltöffnung der Halteschiene des Verbindungselements insbesondere auf das erste Bauteil gerichtet ist und eine diesem zugeordnete C-Tragschiene der Wagenkastenrohbaustruktur übergreift, wobei das Verbindungselement über mindestens ein erstes Befestigungsmittel, das über die mindestens eine im plattenförmigen Element vorgesehene Bohrung mit dem plattenförmigen Element verbunden, insbesondere verschraubt, ist, mit dem ersten Bauteil verbunden ist, und wobei das Verbindungselement über mindestens ein zweites Befestigungsmittel, das über die mindestens eine im Grundsteg der Halteschiene vorgesehene Bohrung mit der Halteschiene verbunden, insbesondere verschraubt, ist, mit dem zweiten Bauteil verbunden ist.The object is further achieved according to a second teaching of the present invention by a connection arrangement with a connecting element of the previously defined type, with a first component, in particular a Wagenkastenrohbaustruktur a rail vehicle or other vehicle, and with a second component, in particular a device part of the vehicle the gap opening of the retaining rail of the connecting element is directed in particular to the first component and a C-mounting rail of the Wagenkastenrohbaustruktur overlaps therewith, wherein the connecting element via at least one first fastening means, connected via the at least one provided in the plate-shaped element bore with the plate-shaped element, in particular screwed, is, is connected to the first component, and wherein the connecting element via at least one second fastening means, via the at least one provided in the base web of the retaining rail Boh tion with the retaining rail connected, in particular screwed, is connected to the second component.

Schließlich wird die Aufgabe gemäß einer dritten Lehre der vorliegenden Erfindung gelöst durch ein Schienenfahrzeug mit mindestens einer solchen Verbindungsanordnung.Finally, the object is achieved according to a third teaching of the present invention by a rail vehicle with at least one such connection arrangement.

Das vorliegend beschriebene Verbindungselement und die entsprechende Verbindungsanordnung hat verschiedene Vorteile. Wie bereits angedeutet, ist die Lösung besonders kompakt und damit platzsparend, sowohl in Längsrichtung als auch quer dazu. Eine Riss- oder Bruchgefahr wird durch eine vergleichsweise hohe Kraftentkopplung deutlich reduziert. Das erfindungsgemäße Verbindungselement ist auch durch die kompakte Bauweise und die Vermeidung von in Längsrichtung über die äußere Begrenzung der insbesondere C-förmigen Halteschiene hinausragenden Abschnitten des plattenförmigen Elements erheblich leichter als die bisher bekannten Lösungen. Das Gewicht wird zusätzlich auch durch die Aussparungen im Grundsteg und im plattenförmigen Element reduziert. Ferner erlaubt das Verbindungselement einen Einbau in allen denkbaren Raumlagen und die Übertragung von Zug- und Druckkräften in allen Richtungen. Durch den einfachen Aufbau des Verbindungselements kann dieses auch längenvariabel ausgeführt werden und ohne weiteres an unterschiedliche Belastungs- und Anwendungsfälle angepasst werden.The connecting element described herein and the corresponding connection arrangement has various advantages. As already indicated, the solution is particularly compact and thus space-saving, both in the longitudinal direction and across it. A risk of cracking or breakage is significantly reduced by a comparatively high power decoupling. The connecting element according to the invention is also considerably lighter than the previously known solutions due to the compact construction and the avoidance of sections of the plate-shaped element projecting beyond the outer boundary of the particular C-shaped retaining rail in the longitudinal direction. The weight is additionally reduced by the recesses in the base bar and in the plate-shaped element. Furthermore, the connecting element allows installation in all conceivable spatial positions and the transmission of tensile and compressive forces in all directions. Due to the simple structure of the connecting element this can also be made variable in length and easily adapted to different load and applications.

Schließlich kann bei einer geeigneten Auswahl der Form der Halteschiene, die nicht zwangsläufig C-förmig sein muss, sondern insbesondere auch G-förmig, U-förmig, I-förmig oder Hut-förmig sein kann, auch die Funktionsintegration erhöht werden, indem das Verbindungselement beispielsweise direkt als Aufnahmewinkel für eine Seitenverkleidung oder Gepäckablage dient.Finally, with a suitable selection of the shape of the retaining rail, which need not necessarily be C-shaped, but in particular G-shaped, U-shaped, I-shaped or hat-shaped, and the functional integration can be increased by the connecting element for example, directly serves as a mounting bracket for a side panel or luggage rack.

Fig. 1a) zeigt eine Schnittansicht eines Verbindungselements 1 für eine schwingungs- und schalldämpfende Verbindung zwischen einer Wagenkastenrohbaustruktur 2 und einem Einrichtungsteil 3. Eine beispielhafte Verbindungsanordnung 12 ist in Fig. 4 gezeigt. Fig. 1a FIG. 1 shows a sectional view of a connection element 1 for a vibration and sound damping connection between a vehicle body shell structure 2 and a device part 3. An exemplary connection arrangement 12 is shown in FIG Fig. 4 shown.

Das Verbindungselement weist eine sich in einer Längsrichtung X erstreckende C-förmige Halteschiene auf, die einen sich in Längsrichtung X erstreckenden Grundsteg 4.1 und zwei vom Grundsteg 4.1 orthogonal ausgehende, voneinander beabstandete, sich in Längsrichtung X erstreckende Seitenstege 4.2 aufweist, die am vom Grundsteg 4.1 entfernten Ende in einem Frontabschnitt 4.21 aufeinander zulaufen, wobei zwischen den beiden Frontabschnitten 4.21 ein in Längsrichtung X verlaufender Spalt 5 ausgebildet ist, wobei in dem Grundsteg 4.1 eine Bohrung 6 in Form einer Gewindebohrung vorgesehen ist. Der Aufbau der C-förmigen Halteschiene 4 ist in den Figuren 2a) und b) dargestellt.The connecting element has a C-shaped retaining rail extending in a longitudinal direction X, which has a base web 4.1 extending in the longitudinal direction X and two side webs orthogonal to the base web 4.1, spaced apart from each other and extending in the longitudinal direction X. The webs 4.1 extending from the base web 4.1 distant end in a front section 4.21 run towards each other, wherein between the two front sections 4.21 in the longitudinal direction X extending gap 5 is formed, wherein in the base web 4.1 a bore 6 is provided in the form of a threaded bore. The structure of the C-shaped support rail 4 is in the FIGS. 2a ) and b) are shown.

Das Verbindungselement 1 weist ferner ein in der C-förmigen Halteschiene 4 gehaltenes plattenförmiges Element 7 auf, das in den Figuren 3a) und b) dargestellt ist. Das plattenförmige Element 7 erstreckt sich im montierten Zustand (Figuren 1a) bis c)) in einer Ebene parallel zum Grundsteg 4.1. Das plattenförmige Element 7 weist zwei Bohrungen 8 auf.The connecting element 1 further comprises a held in the C-shaped support rail 4 plate-shaped element 7, which in the FIGS. 3a ) and b) is shown. The plate-shaped element 7 extends in the mounted state ( FIGS. 1a ) to c)) in a plane parallel to the base bar 4.1. The plate-shaped element 7 has two holes 8.

Wie die Figuren 1a) bis c) zeigen, ist ein gummielastisches Dämpfungsmaterial 9 vorgesehen, das zwischen der Halteschiene 4 und dem plattenförmigen Element 7 angeordnet ist und in das das plattenförmige Element 7 mit zwei seiner Seitenkanten 7.1, die hier verdickt sind, eingebettet ist, und zwar derart, dass das Element 7 die Halteschiene 4 nicht berührt. Zwischen gummielastischem Dämpfungsmaterial 9 und sowohl Halteschiene 4 als auch plattenförmigem Element 7 besteht ein vulkanisierter Verbund. Die Verdickung des Querschnitts des plattenförmigen Elements 7 im Bereich seiner Seitenkanten 7.1 vergrößert die Kontaktfläche zum vulkanisierten Dämpfungsmaterial 9 und erhöht damit die Sicherheit der Verbindung.As the FIGS. 1a ) to c), a rubber-elastic damping material 9 is provided, which is arranged between the support rail 4 and the plate-shaped element 7 and in which the plate-shaped element 7 is embedded with two of its side edges 7.1, which are thickened here, in such a way the element 7 does not touch the retaining rail 4. Between rubber elastic damping material 9 and both support rail 4 and plate-shaped element 7 is a vulcanized composite. The thickening of the cross section of the plate-shaped element 7 in the region of its side edges 7.1 increases the contact surface to the vulcanized Damping material 9 and thus increases the security of the connection.

Die Bohrungen 8 in dem plattenförmigen Element 7 liegen, bezogen auf die Längsrichtung X, innerhalb der äußeren Begrenzung der C-förmigen Halteschiene 4. Im dargestellten Ausführungsbeispiel liegt sogar das gesamte plattenförmige Element 7 innerhalb der äußeren Begrenzung der Halteschiene 4, bezogen auf die Längsrichtung X und bezogen auf eine Richtung Y quer zur Längsrichtung X.The holes 8 in the plate-shaped element 7 lie, relative to the longitudinal direction X, within the outer boundary of the C-shaped support rail 4. In the illustrated embodiment, even the entire plate-shaped element 7 is within the outer boundary of the support rail 4, with respect to the longitudinal direction X. and in a direction Y transverse to the longitudinal direction X.

Bei dem Verbindungselement (Figuren 1a) bis c)) liegt, bezogen auf die Längsrichtung X, die Bohrung 6 in der Halteschiene zwischen den Bohrungen 8 in dem plattenförmigen Element 7, wobei alle Bohrungsachsen in Längsrichtung X hintereinander und damit in einer Ebene liegen.In the connection element ( FIGS. 1a ) to c)), based on the longitudinal direction X, the bore 6 in the support rail between the holes 8 in the plate-shaped element 7, wherein all bore axes in the longitudinal direction X one behind the other and thus lie in one plane.

Ferner ist vorgesehen, dass in der Richtung Y koaxial zu der einen in der Halteschiene 4 vorgesehenen Bohrung 6 Bohrungen 11 im plattenförmigen Element 7 vorgesehen sind, deren Querschnitt größer als der Querschnitt der in der Halteschiene 4 vorgesehenen Bohrung 6 ist.In the illustrated embodiment, it is further provided that in a direction Y transverse to the longitudinal direction X coaxial with the provided in the plate-shaped element 7 holes 8 a bore 10 in the base web 4.1 of the support rail 4 is provided, whose cross section is larger than the cross section of the plate-shaped element. 7 provided holes 8 is. It is further provided that in the direction Y coaxial to the one provided in the support rail 4 bore 6 holes 11 are provided in the plate-shaped element 7, whose cross section is larger than the cross section of the provided in the support rail 4 bore 6.

Wie insbesondere Fig. 2b) zeigt, liegen die Ausnehmungen 10 und die Bohrung 6 in einem verdickten Abschnitt 4.11 des Grundstegs 4.1 der Halteschiene 4. Der verdickte Abschnitt 4.11 erstreckt sich über die gesamte Länge L der Halteschiene 4.In particular Fig. 2b ), the recesses 10 and the bore 6 lie in a thickened section 4.11 of the base web 4.1 of the retaining rail 4. The thickened section 4.11 extends over the entire length L of the retaining rail. 4

Wie Fig. 3b) ferner zeigt, liegen die Bohrungen 8 und die Ausnehmung 11 in einem planen Abschnitt 7.2 mit gleichmäßiger Dicke, der sich zwischen den verdickten Seitenkanten 7.1 erstreckt. Der Abschnitt 7.2 erstreckt sich über die gesamte Länge 1 des plattenförmigen Elements 7.As Fig. 3b ) Further, the holes 8 and the recess 11 are in a planar section 7.2 with a uniform thickness, which extends between the thickened side edges 7.1. The section 7.2 extends over the entire length 1 of the plate-shaped element 7.

Fig. 4 zeigt schließlich eine Verbindungsanordnung 12 mit einem Verbindungselement 1, wie es zuvor beschrieben wurde, mit einem ersten Bauteil 2, das hier die Wagenkastenrohbaustruktur eines Schienenfahrzeugs ist, und mit einem zweiten Bauteil 3, das hier ein Einrichtungsteil des Schienenfahrzeugs ist. Das Verbindungselement 1 ist über ein erstes Befestigungsmittel 13, das über die im plattenförmigen Element 7 vorgesehenen Bohrungen 8 mit dem plattenförmigen Element 7 verschraubt ist, mit der Wagenkastenrohbaustruktur 2 verbunden. Ferner ist das Verbindungselement 1 über ein zweites Befestigungsmittel 14, das über die im Grundsteg 4.1 der Halteschiene 4 vorgesehene Bohrung 6 mit der Halteschiene 4 verschraubt ist, mit dem Einrichtungsteil 3 verbunden. Die Spaltöffnung der Halteschiene 4 - gemeint ist der Spalt 5 - weist dabei in Richtung auf die Wagenkastenrohbaustruktur 2 und übergreift unter allen Lastfällen berührungsfrei dessen C-Tragschiene, so dass das plattenförmige Element 7 am Kopf der C-Tragschiene anliegt und mittels des mindestens aus einer Schraube und einem Nutenstein bestehenden Befestigungsmittels 14 an der C-Tragschiene festgeklemmt ist. Fig. 4 shows a connection assembly 12 with a connecting element 1, as described above, with a first component 2, which here is the Wagenkastenrohbausstruktur a rail vehicle, and with a second component 3, which is here a device part of the rail vehicle.
