Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Antriebseinheit für ein Türblatt, insbesondere für eine Passagierschienenfahrzeugtüre.The invention relates to a drive unit for a door leaf, in particular for a passenger rail vehicle door.

Stand der TechnikState of the art

Passagierraumtüren von Schienenfahrzeugen werden häufig als sogenannte Schiebe- bzw. Schwenkschiebetüren mit einem Kraftantrieb ausgeführt. Je nach Einsatzzweck werden diese Türen ein oder zweiflügelig aufgebaut. Als Kraftantrieb sind elektrische oder pneumatische Antriebe gebräuchlich. Diese Antriebe weisen eine Kraftquelle auf, deren Dreh- bzw. Hubkraft auf das bzw. die Türblätter übertragen wird wodurch diese Türblätter zwischen der Offenstellung und der Geschlossenstellung bewegt werden. Einer gebräuchlichen Bauweise zufolge wirkt ein Antriebsmotor über einen Zahnriemen oder eine Antriebsspindel auf die Türblätter. Bei zweiflügeligen Türen werden beide Türblätter bei elektrischen Antrieben üblicherweise gemeinsam betätigt. In praktischen Ausführungsformen von kraftunterstützten Türantrieben treten mehrere Probleme auf, die mit den Lösungen gemäß des Standes der Technik nicht zufriedenstellend gelöst sind. Ein wesentliches Problem betrifft die Montage der Türen, bzw. der Türantriebe. Diese erfolgt aufgrund der Bauteiltoleranzen mit einem hohen Justieraufwand, was die Herstellungskosten eines Schienenfahrzeugs erhöht. Dieser Justieraufwand tritt bei jeder einzelnen Türöffnung des Schienenfahrzeugs auf und bildet deshalb ein großes Optimierungspotential. Ein weiteres Problem bilden die Verformungen des Schienenfahrzeugs unter Last. Da insbesondere bei Nahverkehrsfahrzeugen (U-Bahnen, S-Bahnen, Straßenbahnen) der Anteil der Masse der Passagiere einen großen Teil der Fahrzeuggesamtmasse bestimmt, treten infolge dieser Beladung Verformungen des Fahrzeugs, insbesondere im Bereich der Türöffnungen auf. Diese Verformungen dürfen den Betrieb der kraftunterstützten Türen nicht beeinträchtigen, wobei zur Kompensation dieser Verformungen sehr komplizierte Einrichtungen vorgesehen werden. Insbesondere können diese Verformungen zu Verspannungen des Türantriebsstranges führen, wodurch erhöhter Verschleiß hervorgerufen wird.Passenger room doors of rail vehicles are often designed as so-called sliding or sliding doors with a power drive. Depending on the intended use, these doors are constructed with one or two leaves. As a power drive electrical or pneumatic actuators are in use. These drives have a power source whose rotational or lifting force is transmitted to the door leaf or leaves whereby these leaves are moved between the open position and the closed position. According to a common design, a drive motor acts on the door leaves via a toothed belt or drive spindle. In the case of double-leaf doors, both door leaves are usually actuated together in the case of electric drives. In practical embodiments of power assisted door operators, there are several problems not satisfactorily solved by the prior art solutions. A major problem concerns the installation of the doors or the door drives. This is due to the component tolerances with a high Justieraufwand, which increases the cost of a rail vehicle. This adjustment effort occurs at each door opening of the rail vehicle and therefore forms a great potential for optimization. Another problem is the deformation of the rail vehicle under load. Since, in particular in suburban vehicles (subways, suburban trains, trams) determines the proportion of the mass of passengers a large part of the total vehicle mass, occur as a result of this load deformations of the vehicle, especially in the door openings. These deformations must not interfere with the operation of the power-assisted doors, and very complicated facilities are provided to compensate for these deformations. In particular, these deformations can lead to tension of the door drive train, whereby increased wear is caused.

Aus der Schrift DE 199 54 623 A1 ist ein Antrieb für ein- oder zweiflügelige Schiebetüren bekannt, welcher platzsparend in einem Torprofil angeordnet ist und einen Hohlwellenmotor einsetzt.From the Scriptures DE 199 54 623 A1 is a drive for single or double-leaf sliding doors known, which is arranged to save space in a door profile and uses a hollow shaft motor.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt daher die Aufgabe zugrunde, eine Antriebseinheit für ein Türblatt, insbesondere für eine Passagierschienenfahrzeugtüre aufzubauen.The invention is therefore based on the object to build a drive unit for a door leaf, in particular for a passenger rail vehicle door.

Die Aufgabe wird durch eine Antriebseinheit mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand untergeordneter Ansprüche.The object is achieved by a drive unit with the features of claim 1. Advantageous embodiments are the subject of the subordinate claims.

Dem Grundgedanken der Erfindung nach wird eine Antriebseinheit für ein Türblatt aufgebaut, welche einen elektrischen Antrieb umfasst, wobei die Drehbewegung des elektrischen Antriebs auf eine Spindelmutter wirkt und eine Gewindespindel in die Spindelmutter eingreift, wobei diese Gewindespindel mit dem Türblatt verbunden ist und wobei der elektrische Antrieb gemeinsam mit der Spindelmutter mittels eines sphärischen Lagers mit einem Wagenkasten eines Schienenfahrzeugs verbunden sind.According to the basic idea of the invention, a drive unit for a door leaf is constructed, which comprises an electric drive, wherein the rotary movement of the electric drive acts on a spindle nut and a Threaded spindle engages in the spindle nut, said threaded spindle is connected to the door leaf and wherein the electric drive are connected together with the spindle nut by means of a spherical bearing with a car body of a rail vehicle.

Erfindungsgemäß ist ein elektrischer Antrieb vorgesehen, welcher auf eine Spindelmutter wirkt. Zu dieser Kraftübertragung eignet sich insbesondere ein Zahnriemenantrieb, da solcherart eine schlupffreie Übertragung der Antriebskraft erfolgen kann. Ebenso schlupffrei kann die Kraftübertragung mittels eines Zahnradgetriebes erfolgen, dieses ist jedoch aufwendiger als ein Zahnriemenantrieb. Weiters kann es vorteilhaft sein, einen Keilriemenantrieb vorzusehen, welcher besonders preisgünstig realisiert werden kann.
Der elektrische Antrieb und die Spindelmutter bilden eine mechanische Einheit, wobei insbesondere die Lagerung (beispielsweise Kugellagerung) der Spindelmutter fest mit dem elektrischen Antrieb verbunden ist. Diese Einheit aus elektrischem Antrieb und drehbar gelagerter, von dem elektrischen Antrieb antreibbaren Spindelmutter ist als wesentliche Eigenschaft der Erfindung mittels eines sphärischen Lagers mit dem Wagenkasten eines Schienenfahrzeugs verbunden. Solcherart ist die genannte Einheit gegenüber dem Wagenkasten schwenkbar befestigt.
Ein sphärisches Lager weist einen äußeren Führungsteil mit einer Führungsfläche in Kugelkalottenform auf, wobei ein innerer Teil in dieser Kugelkalottenführung schwenkbar gelagert ist.According to the invention, an electric drive is provided, which acts on a spindle nut. In particular, a toothed belt drive is suitable for this power transmission, since in this way a slip-free transmission of the driving force can take place. Likewise slip-free can be done by means of a gear transmission, but this is more expensive than a toothed belt drive. Furthermore, it may be advantageous to provide a V-belt drive, which can be realized particularly inexpensive.
The electric drive and the spindle nut form a mechanical unit, wherein in particular the bearing (for example, ball bearing) of the spindle nut is firmly connected to the electric drive. This unit of electric drive and rotatably mounted, driven by the electric drive spindle nut is connected as an essential feature of the invention by means of a spherical bearing with the car body of a rail vehicle. In such a way, said unit is pivotally mounted relative to the car body.
A spherical bearing has an outer guide part with a guide surface in Kugelkalottenform, wherein an inner part is pivotally mounted in this Kugelkalottenführung.

Dadurch ist der Vorteil erzielbar, Bauteiltoleranzen sowie Verformungen des Wagenkastens, bzw. der weiteren Bauteile der Türe ausgleichen zu können. Insbesondere können sich durch diese schwenkbare (momentenfreie) Lagerung keine Verspannungen ausbilden und die Antriebskomponenten (Kraftübertragungselemente wie z.B. Zahnräder oder Zahnriemen sowie die Lagerstellen) werden von diesen Verspannungskräften befreit. Dadurch ist der Vorteil erzielbar, eine Antriebseinheit wesentlich kostengünstiger ausführen zu können, da beispielsweise keine Überdimensionierung in Hinblick auf die Verspannungskräfte vorgenommen werden muß. Weiters kann im Betrieb einer erfindungsgemäßen Antriebseinheit der Wartungsaufwand deutlich reduziert werden.As a result, the advantage can be achieved, component tolerances and deformations of the car body, and the other components of the To be able to balance the door. In particular, can be formed by this pivotable (torque-free) storage no tension and the drive components (power transmission elements such as gears or timing belt and the bearing points) are released from these bracing forces. As a result, the advantage can be achieved to be able to perform a drive unit much cheaper, since, for example, no oversizing with respect to the bracing forces must be made. Furthermore, during operation of a drive unit according to the invention, the maintenance effort can be significantly reduced.

Eine Gewindespindel greift in die Spindelmutter ein, sodaß die Drehbewegung der Spindelmutter in eine Linearbewegung der Gewindespindel gewandelt wird. Diese Gewindespindel ist im Bereich einer ihrer Enden mit einem Türblatt verbunden und überträgt diese Linearbewegung auf das Türblatt.
Die Verbindungsstelle zwischen der Gewindespindel und dem Türblatt ist vorteilhafterweise mit einer momentenfreien Anbindung (Kugelgelenk) auszustatten. Dadurch ist der Vorteil erzielbar, weitere Toleranzen des Türblatts und der Türblattführung ausgleichen zu können und den Antrieb weiter von Verspannungskräften freizuhalten. Bei Türblättern von Schwenkschiebetüren, welche sich zusätzlich zur Bewegung in der Türebene auch noch vertikal dazu bewegen ist diese momentenfreie Anlenkung ganz besonders vorteilhaft.A threaded spindle engages in the spindle nut, so that the rotational movement of the spindle nut is converted into a linear movement of the threaded spindle. This threaded spindle is connected in the region of one of its ends with a door leaf and transmits this linear movement on the door leaf.
The connection point between the threaded spindle and the door leaf is advantageously equipped with a torque-free connection (ball joint). As a result, the advantage can be achieved to be able to compensate for further tolerances of the door leaf and the door leaf guide and to keep the drive further from tension forces. In door leaves of sliding sliding doors, which in addition to the movement in the door level even move vertically to this torque-free linkage is particularly advantageous.

Eine vorteilhafte Fortbildung sieht den Einsatz eines Hohlwellenmotors vor. Ein Hohlwellenmotor weist eine mit einer Längsbohrung ausgestattete Antriebswelle auf, sodaß die Spindelmutter unmittelbar an der Antriebswelle angeordnet werden kann, bzw. kann die Spindelmutter als Teil der Antriebswelle geformt sein. Die Gewindespindel durchdringt in dieser Ausführungsform der Antriebseinheit den elektrischen Antrieb.An advantageous development provides for the use of a hollow shaft motor. A hollow shaft motor has an equipped with a longitudinal bore drive shaft, so that the spindle nut can be arranged directly on the drive shaft, or can the spindle nut as part of Shaft be shaped. The threaded spindle penetrates the electric drive in this embodiment of the drive unit.

Eine weitere Fortbildung der Erfindung ist ein Sicherheitspositionsschalter vorgesehen, welcher das Türblatt in geschlossener Stellung verriegelt und gegen unbeabsichtigte bzw. unbefugte Öffnung (insbesondere während der Fahrt) schützt. Gebräuchliche Sicherheitspositionsschalter weisen eine Halteeinrichtung und einen Sicherheitsbolzen auf, welcher in die Halteeinrichtung einfahrbar ist und von dieser Halteinrichtung fixiert wird. Die Freigabe des Sicherheitsbolzens erfolgt mittels eine elektrischen Signals, bzw. mittels des Abschaltens eines elektrischen Signals. Es ist empfehlenswert, die Halteeinrichtung mit der Antriebs/Spindelmuttereinheit fest zu verbinden und den Sicherheitsbolzen mit dem Türblatt (oder der Gewindespindel) so zu verbinden, dass in geschlossener Position des Türblatts der Sicherheitsbolzen in die Halteeinrichtung ragt. Es ist besonders vorteilhaft, eine erfindungsgemäße Antriebseinheit mit einem Sicherheitspositionsschalter auszustatten, da solcherart auch ein Detektion der Türposition erfolgen kann, was für die Zugsteuerung erforderlich ist und weitere Signalaufnehmer (Endschalter) entfallen können.A further development of the invention, a safety position switch is provided which locks the door leaf in the closed position and protects against unintentional or unauthorized opening (especially while driving). Common safety position switches have a holding device and a safety bolt, which can be moved into the holding device and is fixed by this holding device. The release of the safety bolt by means of an electrical signal, or by switching off an electrical signal. It is advisable to firmly connect the holding device to the drive / spindle nut unit and to connect the safety bolt to the door leaf (or the threaded spindle) so that in the closed position of the door leaf the safety bolt protrudes into the holding device. It is particularly advantageous to equip a drive unit according to the invention with a safety position switch, since such a detection of the door position can be done, which is required for the train control and more signal sensor (limit switch) can be omitted.

Die erfindungsgemäße Antriebseinheit eignet sich für alle in Schienenfahrzeugen, insbesondere Passagierschienenfahrzeugen gebräuchlichen Schiebe- bzw. Schwenkschiebetüren. Bei zweiflügelig ausführten Türen ist es besonders vorteilhaft, dass jeder Türflügel (Türblatt) einen eigenen Antrieb aufweist und solcherart einzeln gesteuert werden kann. Im Fall der Störung eines Antriebes kann dadurch das betroffene Türblatt blockiert werden und das Fahrzeug bis zur Reparatur des Antriebs weiter in Betrieb bleiben.The drive unit according to the invention is suitable for all sliding or sliding sliding doors commonly used in rail vehicles, in particular passenger rail vehicles. In double-leaf doors, it is particularly advantageous that each door (door leaf) has its own drive and can be controlled individually. In the case of failure of a drive can thereby affected Door leaf are blocked and the vehicle remain in operation until the repair of the drive.
