Definitions
- the invention relates to a door drive for the door of a railway car according to the preamble of claim 1 and the DE 10 2012 014 302 ,
- Such door drives for sliding doors, pocket doors or, usually, sliding doors have a rotatably and possibly transverse to its longitudinal axis movably mounted spindle, which can be rotated by a motor in rotation.
- the door leaves are in operative connection via a respective spindle nut with the spindle and are thus moved in the direction of the spindle axis.
- the publication mentioned provides, on the side of the spindle on which the drive motor is arranged to provide an electromechanical parking brake, preferably so that the motor (at least in the moment flow seen) sits between it and the spindle, where appropriate between the motor and spindle still a gear is arranged.
- Such a construction either builds in the axial direction for a very long time or requires a corresponding implementation of the moment between parallel axes, and all this on only one side of the door, while on the other side only one bearing is provided for the spindle.
- the gearbox for motor and brake limits the possibilities of selecting the motor or the brake equally and links their design.
- the Fig. 1 shows, purely schematically and without the portal, floor or roof, a door 1 of a rail transport with two wings 2. Since it is indifferent to the invention, whether the door is a sliding door, a sliding door or a pocket door, the drawing, already to Avoidance of overloading, and since the skilled person knows this all enough, no related components.
- the door 2 are connected via a respective connection 3, which has a cooperating with the spindle spindle nut, connected to a spindle 4.
- the spindle 4 is rotated by a motor 5 in rotation and thus moves the door 2 synchronously in each case in the appropriate direction of the double arrow sixteenth
- a latch 6 At one end of the spindle 4, the motor 5 engages, at the other end of the spindle a latch 6 according to the invention is arranged.
- This locking consists in a first variant of the invention, seen from the spindle, in turn, from a freewheel to allow closing of the door 2 at zero-current motor 5 in any case, a transmission to the necessary on the side of the spindle high To achieve torques, and a quiescent brake, which applies the necessary small torque on this side of the transmission low torque for holding the spindle 4 with small dimensions.
- the transmission preferably has a high gear ratio, for example 30: 1, in order to keep the torque on the side of the quiescent current brake low.
- the quiescent current brake is also a device known per se, in which the brake is released by the quiescent current and is attracted in the event of a failure of the quiescent current, the conditions of use ensure that the power requirement is extremely low since current flows only when the brake is released, which is only the case when the spindle is rotated by the motor 5 and thus the door leaves 2 are moved.
- a releasable coupling 7 may be provided between the gear 9 and the spindle 4.
- the release device for this clutch is connected to a device for emergency opening of the door 1, so that in case of failure of the energy when both the drive motor 5 is no longer to operate, and the quiescent current brake 10 has fallen and thus tightened, a mechanical separation of the spindle 4th from the brake 10 and thus a manual movement of the door 2 by a user is possible.
- the invention is not limited to the illustrated embodiments, but may be variously modified.
- the drive motor 5 which in turn may be a geared motor attack the inventive releasable lock 6 on the motor 5 on the side facing away from the spindle 4, although this will bring even in rare cases benefits with the arrangement and space requirements .
- the principle according to the invention in single-leaf doors, this presents no problems.
- all other measures known in the art such as the provision of encoders in conjunction with the drive motor of Sensors for monitoring the current consumption of the drive motor 5 to detect the impact on obstacles, etc., are easily combined with the invention.

Abstract
Die Erfindung betrifft einen Türantrieb für eine Tür (1) eines Eisenbahnwaggons mit einem Antriebsmotor (5), einer durch diesen Antriebsmotor in Drehung versetzbare Spindel (4), die über eine Verbindung (3) mit einer Spindelmutter zumindest einen Türflügel (2) bewegt. Um den Platzbedarf derartiger Antriebe weiter zu reduzieren ist vorgesehen, dass die Spindel (4) über ein Getriebe (9) drehfest mit einer Ruhestrombremse (10) verbunden ist.The invention relates to a door drive for a door (1) of a railway carriage with a drive motor (5), a spindle (4) which can be rotated by this drive motor and which moves via a connection (3) with a spindle nut at least one door leaf (2). In order to further reduce the space requirement of such drives, it is provided that the spindle (4) is non-rotatably connected via a gear (9) to a quiescent current brake (10).
Description
Die Erfindung betrifft einen Türantrieb für die Tür eines Eisenbahnwaggons entsprechend dem Oberbegriff des Anspruches 1 und der
Derartige Türantriebe für Schiebetüren, Taschentüren oder, zumeist, Schwenkschiebetüren, weisen eine drehbar und unter Umständen quer zu ihrer Längsachse beweglich gelagerte Spindel auf, die durch einen Motor in Drehung versetzt werden kann. Die Türflügel sind über jeweils eine Spindelmutter mit der Spindel in Wirkverbindung und werden so in Richtung der Spindelachse bewegt. Es gibt zahlreiche Varianten dieser Grundkonstruktion, insbesondere was die Anordnung und Ausbildung der einzelnen Teile betrifft.Such door drives for sliding doors, pocket doors or, usually, sliding doors, have a rotatably and possibly transverse to its longitudinal axis movably mounted spindle, which can be rotated by a motor in rotation. The door leaves are in operative connection via a respective spindle nut with the spindle and are thus moved in the direction of the spindle axis. There are numerous variants of this basic construction, in particular as regards the arrangement and design of the individual parts.
Unter Eisenbahnwaggons werden ebenso U-Bahnwaggons, S-Bahnwaggons und selbst Straßenbahnwaggons verstanden, somit prinzipiell die Waggons aller schienengebundenen Massenverkehrsmittel.Under railway wagons are also subway wagons, S-Bahn waggons and even tram wagons understood, thus in principle the wagons of all rail-bound mass transit.
Die eingangs genannte Druckschrift sieht vor, auf der Seite der Spindel, auf der deren Antriebsmotor angeordnet ist, eine elektromechanische Feststellbremse vorzusehen, bevorzugt so, dass der Motor (zumindest im Momentenfluss gesehen) zwischen ihr und der Spindel sitzt, wobei gegebenenfalls zwischen Motor und Spindel noch ein Getriebe angeordnet ist. Eine derartige Konstruktion baut entweder in axialer Richtung sehr lange oder erfordert eine entsprechende Umsetzung des Momentes zwischen parallelen Achsen, und dies alles auf nur einer Seite der Tür, während auf der anderen Seite nur ein Lager für die Spindel vorgesehen ist. Das Getriebe für Motor und Bremse schränkt die Möglichkeiten der Auswahl des Motors bzw. der Bremse gleichermaßen ein und verknüpft deren Auslegung.The publication mentioned provides, on the side of the spindle on which the drive motor is arranged to provide an electromechanical parking brake, preferably so that the motor (at least in the moment flow seen) sits between it and the spindle, where appropriate between the motor and spindle still a gear is arranged. Such a construction either builds in the axial direction for a very long time or requires a corresponding implementation of the moment between parallel axes, and all this on only one side of the door, while on the other side only one bearing is provided for the spindle. The gearbox for motor and brake limits the possibilities of selecting the motor or the brake equally and links their design.
Die
Dieses System hat sich über viele Jahre und in vielfacher Variation bewehrt, ein gewisses Problem ist in letzter Zeit dadurch aufgetaucht, dass die Platzverhältnisse im Bereiche des Türantriebs oberhalb des Türstockes durch die zunehmende Anzahl von Sensoren und Anzeigen und den Versuch die Außenumrisse der Fahrzeuge möglichst eng zu halten zu Platzproblemen gekommen ist. Hier besteht nun das Problem, dass die lösbaren Kupplungen bzw. Bremsen einen hohen Platzbedarf aufweisen, der auch damit zu tun hat, dass alle über die Türbewegungen herrührenden Drehmomente - Normen schreiben die notwendige Zuhaltekraft vor - diese Betriebsbelastungen kommen von Zugsbegegnungen, Beschleunigungen von Massen und Passagieren von der Bremse bzw. Kupplung aufgenommen werden müssen, was deren Abmessungen mitbedingt.This system has proved itself over many years and in many variations, a certain problem has lately emerged from the fact that the space in the areas of the door drive above the door frame by the increasing number of sensors and displays and the attempt the outer outlines of the vehicles as closely as possible to keep space problems has come. Here is the problem that the detachable clutches or brakes have a lot of space, which also has to do with the fact that all over the door movements resulting torque - standards prescribe the necessary locking force - these operating loads come from Zugsbegegnungen, accelerations of masses and Passengers must be taken from the brake or clutch, which mitbedingt their dimensions.
Es besteht daher ein Bedarf an einer Vorrichtung, die die gewünschten Merkmale der genannten Vorrichtungen aufweist, aber mit deutlich weniger Platzbedarf auskommt.There is therefore a need for a device that has the desired features of said devices, but requires significantly less space.
Es ist das Ziel der Erfindung, eine solche Vorrichtung anzugeben.It is the object of the invention to provide such a device.
Diese Ziele werden durch die im kennzeichnenden Teil des Anspruches 1 angegebenen Maßnahmen erreicht; mit anderen Worten es wird die Kupplung bzw. Bremse samt Ihrer Fixiervorrichtung durch eine Ruhestrombremse samt Getriebe ersetzt; bzw. es ist die Spindel über ein Getriebe drehfest mit einer Ruhestrombremse verbunden.These objects are achieved by the measures indicated in the characterizing part of
Es ist interessant, dass trotz des zusätzlichen Getriebes der gesamte Platzbedarf deutlich schrumpft und dass weder bei der Montage noch während des Betriebs Nachteile auftreten.It is interesting that, despite the additional gear, the total space requirement is significantly reduced and that neither during assembly nor during operation disadvantages occur.
In einer Variante kann man auf den Freilauf verzichten und die Fixierung der Spindel direkt der Ruhestrombremse bzw. dem Getriebe unter Ruhestrombremse überantworten.In one variant, you can do without the freewheel and the fixation of the spindle directly override the quiescent current brake or the transmission under quiescent current brake.
Die Erfindung wird im Folgenden anhand der Zeichnung näher erläutert. Dabei zeigt bzw. zeigen
- die
Fig. 1 einen erfindungsgemäß ausgestatteten Türantrieb mit zwei Türflügeln, aber ohne deren Führung, Portal, etc., rein schematisch und - die
Fig. 2 , ebenso schematisch, eine Variante.
- the
Fig. 1 an inventively equipped door drive with two leaves, but without their leadership, portal, etc., purely schematic and - the
Fig. 2 , also schematically, a variant.
Die
Im dargestellten Ausführungsbeispiel ist, wie bereits erwähnt, auf den Mechanismus, der zum Ausstellen der Tür bei Schwenkschiebetüren notwendig ist, nicht Rücksicht genommen worden, da die diesbezüglichen Führungen und Schwenkorgane mit der Erfindung nicht ursächlich zu tun haben, und da deren Darstellung nur die Übersichtlichkeit stören würde, wurde darauf verzichtet.In the illustrated embodiment, as already mentioned, on the mechanism that is necessary for exhibiting the door in swing sliding doors, not taken into account, since the relevant guides and pivoting organs with the invention are not causally related, and since their representation is only the clarity was disturbed, was waived.
Die Spindel 4 wird durch einen Motor 5 in Drehbewegung versetzt und bewegt so die Türflügel 2 synchron jeweils in der passenden Richtung des Doppelpfeiles 16.The
An einem Ende der Spindel 4 greift der Motor 5 an, am anderen Ende der Spindel ist eine erfindungsgemäße Verriegelung 6 angeordnet. Diese Verriegelung besteht bei einer ersten Variante der Erfindung, von der Spindel aus gesehen, der Reihe nach, aus einem Freilauf, um ein Schließen der Türflügel 2 bei stromlosem Motor 5 jedenfalls zu ermöglichen, einem Getriebe, um die auf der Seite der Spindel notwendigen hohen Drehmomente zu erreichen, und einer Ruhestrombremse, die mit geringen Abmessungen das diesseits des Getriebes notwendige geringe Drehmoment zum Halten der Spindel 4 aufbringt. Das Getriebe weist vorzugsweise eine hohe Übersetzung, beispielsweise 30:1, auf, um das Drehmoment auf der Seite der Ruhestrombremse gering zu halten.At one end of the
Wenn es sich bei der Ruhestrombremse auch um eine an sich bekannte Vorrichtung handelt, bei der die Bremse durch den Ruhestrom gelöst und bei Ausfall des Ruhestroms angezogen wird, ist durch die Einsatzbedingungen doch sichergestellt, dass der Strombedarf äußerst gering ist, da Strom nur fließt wenn die Bremse gelöst ist, was nur der Fall ist, wenn die Spindel durch den Motor 5 gedreht wird und damit die Türflügel 2 bewegt werden.If the quiescent current brake is also a device known per se, in which the brake is released by the quiescent current and is attracted in the event of a failure of the quiescent current, the conditions of use ensure that the power requirement is extremely low since current flows only when the brake is released, which is only the case when the spindle is rotated by the
In einer Ausgestaltung der Erfindung ohne Freilauf, wie in
In einer weiteren Ausgestaltung, wie ebenfalls in
Die Erfindung ist nicht auf die dargestellten Ausführungsbeispiele beschränkt, sondern kann verschiedentlich abgewandelt werden. So kann bei passender Ausgestaltung des Antriebsmotors 5, der seinerseits wieder ein Getriebemotor sein kann, die erfindungsgemäße lösbare Verriegelung 6 am Motor 5 auf der der Spindel 4 abgewandten Seite angreifen, wenn dies auch nur in seltenen Fällen Vorteile mit der Anordnung und dem Platzbedarf bringen wird. Es ist selbstverständlich möglich, das erfindungsgemäße Prinzip auch bei einflügeligen Türen anzuwenden, dies stellt keinerlei Probleme dar. Es soll nochmals darauf hingewiesen werden, dass sämtliche anderen im Stand der Technik bekannten Maßnahmen, wie z.B. das Vorsehen von Weggebern in Verbindung mit dem Antriebsmotor, von Sensoren zur Überwachung der Stromaufnahme des Antriebsmotors 5 um den Aufprall auf Hindernisse zu erkennen etc., mit der Erfindung problemlos kombinierbar sind.
