Definitions
- the invention relates to a rail vehicle with at least one sliding door, which is mounted in a wall opening of a vehicle wall of the rail vehicle and has at least one door leaf, which is displaceable for opening and closing.
- the invention has for its object to provide a rail vehicle, in which the described problem of lifting or flapping the sliding doors even in the case of very large pressure differences, especially in Switzerlandbegegnungen or tunnel drives, not at all or at least significantly less than in prior art rail vehicles.
- the invention provides that in the region of the wall opening of the vehicle wall at least one curved seal is mounted and extends due to the curvature of the seal of the door leaf end facing the seal obliquely to the sliding direction of the door leaf.
- a significant advantage of the rail vehicle according to the invention is the fact that due to the curved design of the seal a flat inclined support the seal on the door is ensured; By this inclined support optimal sealing between the door and the vehicle wall is achieved. Even with large pressure differences, as they occur in train encounters or tunnel drives, a lifting of the door leaf or a flutter of the sliding door is usually reliably avoided due to the curved course of the seal.
- the curvature of the seal is preferably based on at least one bent or curved sealing portion.
- the seal is curved in its end portion facing the door opposite to the direction of movement, which has the door during its opening movement. In other words, it is therefore considered advantageous if the seal is bent away from its mounting point on the vehicle wall in the direction of the central region of the wall opening.
- the gasket is arcuate in its end region facing the door leaf and, in the closed position of the door leaf, lies bent toward the door leaf in the direction of the central region of the closed door leaf.
- the door has at least one stop element and in the closed position of the door leaf, the seal abuts the stop element and due to the contact with the stop element the door leaf seals against the vehicle wall.
- the one or more stop elements may be attached to the door as previously separate components or integrally formed on the vehicle wall.
- the stop element an inclined or curved abutment surface which extends obliquely or bent away from the plane of movement (plane of sliding movement) of the sliding door to the outside, and the door leaf-facing end portion of the gasket in the closed position of the door leaf abuts the inclined or curved abutment surface.
- the curvature of the end portion of the bend in the closed position of the door leaf against the curved abutment surface corresponds to the curvature of the curved abutment surface.
- the door has a plurality of stops.
- the plurality of stops is preferably formed by a sawtooth structure having a plurality of teeth.
- the seal is preferably located on the saw tooth edge of one of the teeth of the sawtooth structure facing the center of the door.
- the sawtooth edge of the saw center facing at least one of the teeth or in each case all the teeth of the sawtooth structure is bent.
- the bending of the sawtooth edge facing the center of the door corresponds to at least one of the teeth or all teeth of the sawtooth structure of the bend of the end section of the seal facing the door leaf.
- the tooth height of the teeth in at least one section of the sawtooth structure preferably increases in the direction of the center of the door.
- the plurality of stops may be formed by a trapezoidal structure. Accordingly, it is considered advantageous if the door has a trapezoidal structure with a plurality of juxtaposed trapezoidal locking elements and the seal abuts in the closed position of the door leaf at the door center side facing edge of one of the trapezoidal locking elements.
- a door leaf-side seal is attached to the door, which rests in the closed position of the door on a mounted on the vehicle wall stop member and the Door leaf-side seal with the attached to the vehicle wall seal a sealed interior space between the door and the vehicle wall.
- the sliding door may for example have one or two door leaves, which can be moved in each case.
- the door leaves are preferably moved in the opposite direction to open and close the sliding door.
- FIG. 1 shows an embodiment of a rail vehicle 10, which is equipped with a sliding door 20.
- the sliding door 20 may be, for example, a pocket sliding door.
- the sliding door 20 is mounted in a wall opening 31 of a lateral vehicle wall, hereinafter referred to as side wall 30, of the rail vehicle 10.
- the sliding door 20 includes two door leaves 21 and 22 that slide along the longitudinal direction of the rail vehicle 10 can be.
- the left door 21 to open the sliding door 20 along the direction of arrow P1 to the left and move the right in Figure 1 door leaf 22 along the direction of the arrow P2 to the right.
- FIG. 2 shows the sliding door 20 and their interaction with the side wall 30 of the rail vehicle 10 according to Figure 1 in more detail, in a cross-section viewed from above.
- a curved seal 40 is attached, which is also referred to below as the side wall-side seal 40 and whose end portion rests against the outside 22a of the door leaf 22. Due to the curvature of the side wall-side seal 40, the end region 41 of the seal 40 facing the door leaf 22 extends obliquely to the sliding direction B of the door leaf 22 when the sliding door 20 is opened.
- the side wall-side seal 40 is arcuate, so that the seal 40, starting from its mounting point 42 in the region of the wall opening 31 of the side wall 30 extends arcuately in the direction of the central region of the wall opening 31 or arcuately in the central region of the closed door leaf 22.
- a door leaf-side seal 60 is provided in addition to the curved side wall-side seal 40, which is attached to the outer edge 22b of the door leaf 22 and extends arcuately in the direction of an L-shaped side wall-side stop member 33 and rests in the closed position of the door leaf 22 on this.
- the interior 12 of the rail vehicle 10 is reliably sealed by the door leaf-side seal 60 and the side wall-side seal 40, regardless of whether the pressure in the interior 12 of the rail vehicle 10 is greater or less than that External pressure or the pressure outside of the rail vehicle 10 is.
- the door-leaf-side seal 60 will press against the side wall-side stop element 33, so that a reliable sealing of the door leaf 22 with respect to the side wall 30 is achieved.
- a seal is achieved by the curved side wall-side seal 40, which is pressed flat against the door leaf 22 of the sliding door 20 and ensures a seal between the door leaf 22 and side wall 30.
- FIG. 3 shows by way of example with reference to the door leaf 22 a particularly preferred embodiment in which the door leaf 22 is equipped with at least one stop element 100 on which the end portion 41 of the curved side wall-side seal 40 rests in the closed state of the door leaf 22.
- the stop element 100 may have been mounted as a separate component on the outside 22a of the door leaf 22 or integrally formed on the outside 22a of the door leaf 22.
- the stop element 100 has an inclined abutment surface 110, which extends obliquely outward from the movement plane BE or the plane of the sliding movement of the sliding door 20, as shown by way of example in FIG FIG. 3 is shown.
- the abutment surface 110 can also extend in a curved form outward from the movement plane BE or the plane of the sliding movement of the sliding door 20.
- the side wall-side seal 40 is provided with a particularly curved arc section 43, which forms a transition section between the mounting location 42 of the seal 40 and the end portion 41. Due to this particularly pronounced curvature of the curved portion 43, a course of the end portion 41 is ensured, which is optimally adapted to the course of the inclined stop surface 110 of the stop member 100.
- the seal 40 is held by means of a holding member 200 on the side wall 30 of the rail vehicle 10.
- the side wall seal 40 may also be secured to the side wall 30 by screws, rivets, or otherwise.
- the door leaf 22 With a view to a tolerance-insensitive sealing of the door leaf 22 relative to the side wall 30 by means of the side wall-side seal 40, it is considered advantageous if the door leaf 22 not only a single stop element 100 for supporting the end portion 41 of the seal 40 provides, but a plurality of stop elements. In the case of a plurality of stop elements, a seal can be ensured by the end portion 41 even if the door leaf 22 does not exactly a certain end position in the closed state of the sliding door 20 occupies, but due to tolerances a slightly different.
- FIG. 4 shows an embodiment of a door leaf 22 which is equipped with a plurality of stop members 100.
- the stopper elements 100 are formed by teeth 301 of a sawtooth structure 300.
- the teeth 301 of the sawtooth structure 300 are made symmetrical, and the sawtooth edges of the teeth 301 are each rectilinear.
- the FIG. 5 shows another embodiment for a sawtooth structure 300, with which a plurality of stop elements for the door leaf 22 is provided.
- the teeth 301 are asymmetrical and each have a curved sawtooth edge 310 and a straight sawtooth edge 320 on.
- the bent sawtooth edge 310 of the teeth 301 faces the door center TM of the sliding door 20, respectively, and the straight sawtooth edge 320 of the teeth 301 faces away from the door center TM of the sliding door 20 and faces the side wall 30, respectively.
- FIG. 6 1 shows an exemplary embodiment of a sawtooth structure 300 in which the height of the teeth 301 of the sawtooth structure 300 varies.
- the sawtooth structure 300 has at least a portion in which the tooth height of the teeth 301 increases in the direction of the door center TM. That's how it shows FIG. 6 for example, that the height H1 is greater than the height H2.
- the varying tooth height of the teeth 301 of the sawtooth structure 300 allows the end portion 41 of the sidewall-side seal 40 to pass between the two teeth 301 at the optimum height to rest on the sawtooth structure 300.

Description
Die Erfindung bezieht sich auf ein Schienenfahrzeug mit zumindest einer Schiebetür, die in einer Wandöffnung einer Fahrzeugwand des Schienenfahrzeugs montiert ist und zumindest einen Türflügel aufweist, der zum Öffnen und Schließen verschiebbar ist.The invention relates to a rail vehicle with at least one sliding door, which is mounted in a wall opening of a vehicle wall of the rail vehicle and has at least one door leaf, which is displaceable for opening and closing.
Bei Zugbegegnungen und Tunnelfahrten von Schienenfahrzeugen können sehr große Druckdifferenzen zwischen dem Innenraum des Schienenfahrzeugs und der Umgebung auftreten, so dass ein Flattern durch Abheben der Dichtgummis an den Schiebetüren, insbesondere im Falle von Taschenschiebetüren, auftreten kann.When train encounters and tunnel runs of rail vehicles very large pressure differences between the interior of the rail vehicle and the environment may occur, so that a flutter by lifting the rubber seals on the sliding doors, especially in the case of sliding doors can occur.
Der Erfindung liegt die Aufgabe zugrunde, ein Schienenfahrzeug anzugeben, bei dem die beschriebene Problematik eines Abhebens bzw. Flatterns der Schiebetüren auch im Falle sehr großer Druckdifferenzen, insbesondere bei Zugbegegnungen oder Tunnelfahrten, gar nicht oder zumindest deutlich geringer auftritt als bei vorbekannten Schienenfahrzeugen.The invention has for its object to provide a rail vehicle, in which the described problem of lifting or flapping the sliding doors even in the case of very large pressure differences, especially in Zugbegegnungen or tunnel drives, not at all or at least significantly less than in prior art rail vehicles.
Diese Aufgabe wird erfindungsgemäß durch ein Schienenfahrzeug mit den Merkmalen gemäß Patentanspruch 1 gelöst. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Schienenfahrzeugs sind in Unteransprüchen angegeben.This object is achieved by a rail vehicle with the features according to claim 1. Advantageous embodiments of the rail vehicle according to the invention are specified in subclaims.
Danach ist erfindungsgemäß vorgesehen, dass im Bereich der Wandöffnung der Fahrzeugwand mindestens eine gekrümmte Dichtung angebracht ist und sich aufgrund der Krümmung der Dichtung der dem Türflügel zugewandte Endbereich der Dichtung schräg zur Schieberichtung des Türflügels erstreckt.Thereafter, the invention provides that in the region of the wall opening of the vehicle wall at least one curved seal is mounted and extends due to the curvature of the seal of the door leaf end facing the seal obliquely to the sliding direction of the door leaf.
Ein wesentlicher Vorteil des erfindungsgemäßen Schienenfahrzeugs ist darin zu sehen, dass aufgrund der gekrümmten Ausführung der Dichtung eine flächig schräg verlaufende Auflage der Dichtung auf dem Türflügel gewährleistet wird; durch diese schräg verlaufende Auflage wird eine optimale Abdichtung zwischen Türflügel und Fahrzeugwand erreicht. Selbst bei großen Druckdifferenzen, wie sie bei Zugbegegnungen oder Tunnelfahrten auftreten, wird aufgrund des gekrümmten Verlaufs der Dichtung ein Abheben des Türflügels bzw. ein Flattern der Schiebetür in aller Regel zuverlässig vermieden.A significant advantage of the rail vehicle according to the invention is the fact that due to the curved design of the seal a flat inclined support the seal on the door is ensured; By this inclined support optimal sealing between the door and the vehicle wall is achieved. Even with large pressure differences, as they occur in train encounters or tunnel drives, a lifting of the door leaf or a flutter of the sliding door is usually reliably avoided due to the curved course of the seal.
Die Krümmung der Dichtung beruht vorzugsweise auf zumindest einem abgebogenen oder gewölbten Dichtungsabschnitt.The curvature of the seal is preferably based on at least one bent or curved sealing portion.
Mit Blick auf die Richtung der Krümmung der gekrümmten Dichtung wird es als vorteilhaft angesehen, wenn die Dichtung in ihrem dem Türflügel zugewandten Endbereich entgegen derjenigen Bewegungsrichtung gekrümmt ist, die der Türflügel während seiner Öffnungsbewegung aufweist. Mit anderen Worten wird es also als vorteilhaft angesehen, wenn die Dichtung ausgehend von ihrer Montagestelle an der Fahrzeugwand in Richtung des Mittenbereichs der Wandöffnung weggebogen ist.With regard to the direction of the curvature of the curved seal, it is considered advantageous if the seal is curved in its end portion facing the door opposite to the direction of movement, which has the door during its opening movement. In other words, it is therefore considered advantageous if the seal is bent away from its mounting point on the vehicle wall in the direction of the central region of the wall opening.
Bevorzugt ist die Dichtung in ihrem dem Türflügel zugewandten Endbereich bogenförmig und liegt in der geschlossenen Stellung des Türflügels in Richtung des Mittenbereichs des geschlossenen Türflügels gebogen an dem Türflügel an.Preferably, the gasket is arcuate in its end region facing the door leaf and, in the closed position of the door leaf, lies bent toward the door leaf in the direction of the central region of the closed door leaf.
Um eine optimale Abdichtung durch die gekrümmte Dichtung zwischen Türflügel und Fahrzeugwand zu erreichen, wird es als vorteilhaft angesehen, wenn der Türflügel mindestens ein Anschlagselement aufweist und in der geschlossenen Stellung des Türflügels die Dichtung an dem Anschlagselement anliegt und aufgrund der Anlage an dem Anschlagselement den Türflügel gegenüber der Fahrzeugwand abdichtet. Das oder die Anschlagselemente können an dem Türflügel als vormals separate Komponenten angebracht oder einteilig an der Fahrzeugwand angeformt sein.In order to achieve optimum sealing by the curved seal between the door leaf and the vehicle wall, it is considered advantageous if the door has at least one stop element and in the closed position of the door leaf, the seal abuts the stop element and due to the contact with the stop element the door leaf seals against the vehicle wall. The one or more stop elements may be attached to the door as previously separate components or integrally formed on the vehicle wall.
Bezüglich der Ausgestaltung eines solchen Anschlagselements wird es als vorteilhaft angesehen, wenn das Anschlagselement eine schräge oder gebogene Anschlagsfläche aufweist, die sich schräg oder gebogen von der Bewegungsebene (Ebene der Schiebebewegung) der Schiebetür nach außen wegerstreckt, und der dem Türflügel zugewandte Endabschnitt der Dichtung in der geschlossenen Stellung des Türflügels an der schrägen oder gebogenen Anschlagsfläche anliegt.With regard to the configuration of such a stop element, it is considered advantageous if the stop element an inclined or curved abutment surface which extends obliquely or bent away from the plane of movement (plane of sliding movement) of the sliding door to the outside, and the door leaf-facing end portion of the gasket in the closed position of the door leaf abuts the inclined or curved abutment surface.
Vorzugsweise entspricht die Krümmung des in der geschlossenen Stellung des Türflügels an der gebogenen Anschlagsfläche anliegenden Endabschnitts der Biegung der gebogenen Anschlagsfläche.Preferably, the curvature of the end portion of the bend in the closed position of the door leaf against the curved abutment surface corresponds to the curvature of the curved abutment surface.
Um ein optimales Anliegen der gekrümmten Dichtung an dem Türflügel auch bei schwankender Endposition zu gewährleisten, wird es als vorteilhaft angesehen, wenn der Türflügel eine Mehrzahl an Anschlägen aufweist.In order to ensure an optimal concern of the curved seal on the door even at fluctuating end position, it is considered advantageous if the door has a plurality of stops.
Die Mehrzahl an Anschlägen wird vorzugsweise durch eine Sägezahnstruktur mit einer Mehrzahl an Zähnen gebildet. Die Dichtung liegt in der geschlossenen Stellung des Türflügels bevorzugt an der der Türmitte zugewandten Sägezahnkante eines der Zähne der Sägezahnstruktur an.The plurality of stops is preferably formed by a sawtooth structure having a plurality of teeth. In the closed position of the door leaf, the seal is preferably located on the saw tooth edge of one of the teeth of the sawtooth structure facing the center of the door.
Besonders bevorzugt ist die der Türmitte zugewandte Sägezahnkante zumindest eines der Zähne oder jeweils aller Zähne der Sägezahnstruktur gebogen.Particularly preferably, the sawtooth edge of the saw center facing at least one of the teeth or in each case all the teeth of the sawtooth structure is bent.
Besonders vorteilhaft ist es, wenn die Biegung der der Türmitte zugewandten Sägezahnkante zumindest eines der Zähne oder aller Zähne der Sägezahnstruktur der Biegung des dem Türflügel zugewandten Endabschnitts der Dichtung entspricht.It is particularly advantageous if the bending of the sawtooth edge facing the center of the door corresponds to at least one of the teeth or all teeth of the sawtooth structure of the bend of the end section of the seal facing the door leaf.
Darüber hinaus ist es vorteilhaft, wenn die Zahnhöhe der Zähne der an dem Türflügel angebrachten oder angeformten Sägezahnstruktur variiert.Moreover, it is advantageous if the tooth height of the teeth of the sawtooth structure attached to or molded onto the door leaf varies.
Im Falle einer Variation der Zahnhöhe steigt die Zahnhöhe der Zähne in zumindest einem Abschnitt der Sägezahnstruktur bevorzugt in Richtung Türmitte an.In the case of a variation of the tooth height, the tooth height of the teeth in at least one section of the sawtooth structure preferably increases in the direction of the center of the door.
Alternativ oder zusätzlich kann die Mehrzahl an Anschlägen durch eine Trapezstruktur gebildet sein. Demgemäß wird es als vorteilhaft angesehen, wenn der Türflügel eine Trapezstruktur mit einer Mehrzahl an nebeneinander angeordneten trapezförmigen Rastelementen aufweist und die Dichtung in der geschlossenen Stellung des Türflügels an der der Türmitte zugewandten Seitenkante eines der trapezförmigen Rastelemente anliegt.Alternatively or additionally, the plurality of stops may be formed by a trapezoidal structure. Accordingly, it is considered advantageous if the door has a trapezoidal structure with a plurality of juxtaposed trapezoidal locking elements and the seal abuts in the closed position of the door leaf at the door center side facing edge of one of the trapezoidal locking elements.
Um eine Abdichtung des Türflügels auch im Falle eines Überdrucks im Innenraum des Schienenfahrzeugs zu gewährleisten, wird es als vorteilhaft angesehen, wenn an dem Türflügel eine türflügelseitige Dichtung angebracht ist, die in der geschlossen Position des Türflügels an einem an der Fahrzeugwand angebrachten Anschlagselement anliegt und die türflügelseitige Dichtung mit der an der Fahrzeugwand angebrachten Dichtung einen abgedichteten Innenraum zwischen Türflügel und Fahrzeugwand begrenzt.In order to ensure a seal of the door, even in the event of overpressure in the interior of the rail vehicle, it is considered advantageous if a door leaf-side seal is attached to the door, which rests in the closed position of the door on a mounted on the vehicle wall stop member and the Door leaf-side seal with the attached to the vehicle wall seal a sealed interior space between the door and the vehicle wall.
Die Schiebetür kann beispielsweise ein oder zwei Türflügel aufweisen, die sich jeweils verschieben lassen. Im Falle von zwei Türflügeln werden die Türflügel zum Öffnen und Schließen der Schiebetür bevorzugt in entgegengesetzte Richtung verschoben.The sliding door may for example have one or two door leaves, which can be moved in each case. In the case of two door leaves, the door leaves are preferably moved in the opposite direction to open and close the sliding door.
