Description

Die Erfindung betrifft einen Türantrieb für eine Schwenktür eines Fahrzeugs zum Personentransport gemäß dem Oberbegriff des Anspruches 1.The invention relates to a door drive for a swing door of a vehicle for passenger transport according to the preamble of claim 1.

Aus dem Stand der Technik sind die unterschiedlichsten Arten von Schwenktüren bekannt. Zum einen sind in diesem Zusammenhang Schwenkschiebetüren bekannt, die z. B. in der DE 37 42 279 C2 , der DE 41 33 179 A1 , beschrieben sind.From the prior art, the most diverse types of swing doors are known. On the one hand pivot sliding doors are known in this context, the z. B. in the DE 37 42 279 C2 , of the DE 41 33 179 A1 , are described.

Darüber hinaus sind reine Schwenktüren bekannt, wobei nach dem Stand der Technik solche Schwenktüren sich dadurch auszeichnen, dass diese Schwenktüren unter anderem über eine Drehsäule verfügen, wobei in der Drehsäule ein Spindelantrieb vorgesehen ist, der eine Hubbewegung in eine Drehbewegung umsetzt. Hierbei ist eine Kopfplatte vorgesehen, wobei die Kopfplatte einen Antriebszylinder aufnimmt, wobei die Kopfplatte oben im Türportal angeordnet ist und insofern die Höhe des Türdurchtritts selbst eingeschränkt ist. In diesem Zusammenhang ist ein weiterer Türantrieb bekannt, der ebenfalls auf einem Spindelantrieb basiert, wobei bei diesem Türantrieb, um den Türflügel in der geschlossenen Position zu fixieren, der Türantrieb am Ende der Schließbewegung eine Vertikalbewegung ausführt, die dafür sorgt, dass der Türflügel in am Türportal angeordnete, keilförmige Verriegelungselemente einläuft.In addition, pure swing doors are known, in the prior art such swing doors are characterized in that these swing doors have, inter alia, a rotary column, wherein in the rotary column, a spindle drive is provided which converts a lifting movement into a rotary motion. Here, a top plate is provided, wherein the top plate receives a drive cylinder, wherein the top plate is located above in the door portal and thus the height of the door passage itself is limited. In this context, another door drive is known, which is also based on a spindle drive, wherein in this door drive to fix the door in the closed position, the door drive at the end of the closing movement performs a vertical movement, which ensures that the door in on Door portal arranged wedge-shaped locking elements enters.

Die zuvor beschriebenen Spindelantriebe sind allesamt pneumatisch über Kolben-Zylinderantriebe betätigbar, wobei aus dem Stand der Technik allerdings ebenfalls ein elektrischer Türantrieb bekannt ist, wobei ein solcher elektrischer Türantrieb im Bereich der Einstiegsstufe des Fahrzeugs angeordnet ist. Die Anordnung eines solchen Motors im Bereich der Einstiegsstufe beschränkt naturgemäß die Einstiegsbreite des Türportals, was insbesondere dann von Nachteil ist, wenn beispielsweise im Bereich eines solchen Türeinstiegs eine Rampe für Rollstuhlfahrer angeordnet werden soll.The spindle drives described above are all pneumatically actuated via piston-cylinder drives, although an electric door drive is also known from the prior art, wherein such an electric door drive is arranged in the entry level of the vehicle. The arrangement of such a motor in the entry level naturally limits the entrance width of the door portal, which is particularly disadvantageous if, for example, in the area of such a door entry ramp for wheelchair users to be arranged.

Zusammenfassend ist demzufolge festzuhalten, dass bei Türantrieben für Schwenktüren von Personentransportfahrzeugen, wie z. B. Bussen, durch die Antriebseinrichtung, sei sie als pneumatischer oder elektrischer Antrieb ausgebildet, immer einen erhöhten Platzbedarf entweder im Decken- oder Bodenbereich des Portals zur Folge hat, was Einschränkungen in der Durchgangshöhe oder in der Breite der Durchgangsöffnung zur Folge hat.In summary, it should therefore be noted that in door drives for swing doors of passenger transport vehicles, such. As buses, by the drive device, whether designed as a pneumatic or electric drive, always has an increased space requirement either in the ceiling or floor area of the portal result, which has restrictions in the passage height or in the width of the passage opening result.

Aus der DE 20 2007 015 770 U1 ist insofern eine Antriebsvorrichtung für eine Tür eines Fahrzeugs des öffentlichen Personenverkehrs mit einem Drehsäulenantrieb bekannt, wobei sowohl der Antriebsmotor als auch das Getriebe in der Drehsäule untergebracht sind. Darüber hinaus ist in der Drehsäule eine Bremse untergebracht, wobei die Bremse unter der Wirkung der Kraft einer Feder in die Blockierstellung einrückt. Das Lösen der Bremse kann elektromagnetisch oder mechanisch erfolgen, ohne dass dies näher beschrieben ist.From the DE 20 2007 015 770 U1 In this respect, a drive device for a door of a public transport vehicle with a rotary column drive is known, wherein both the drive motor and the transmission are accommodated in the rotary column. In addition, a brake is housed in the rotary column, wherein the brake engages under the action of the force of a spring in the blocking position. The release of the brake can be electromagnetically or mechanically, without being described in more detail.

Aus der DE 20 2008 001 065 U1 ist eine Antriebseinrichtung für die Drehsäule einer Schwenktür eines Fahrzeuges bekannt, wobei in der Drehsäule der einen Motor mit einem Planetengetriebe umfassende Antrieb sich befindet.From the DE 20 2008 001 065 U1 a drive device for the rotary column of a swing door of a vehicle is known, wherein in the rotary column of a motor with a planetary gear comprehensive drive is located.

Das Drehmoment des Antriebs im oberen Drehsäulenteil wird durch eine Führungswelle aufgenommen, die in einem Haltebauteil in der Karosserie des Fahrzeugs unverdrehbar gelagert ist. Der Antriebsmotor weist eine Bremse auf, die als Low-Active oder High-Active Bremse ausgeführt ist, und durch die der Antriebsmotor während des Normalbetriebs der Antriebseinrichtung blockiert ist. Um die Tür notzuentriegeln, ist die Bremse zu lösen.The torque of the drive in the upper pivot column part is received by a guide shaft which is mounted non-rotatably in a holding member in the body of the vehicle. The drive motor has a brake, which is designed as a low-active or high-active brake, and is blocked by the drive motor during normal operation of the drive device. To unlock the door, release the brake.

Die der Erfindung zugrunde liegende Aufgabe besteht darin, bei einem Türantrieb mit in der Drehsäule angeordnetem Antriebsmotor mit nachgeschaltetem Planetengetriebe auf einfache Weise für eine Entriegelung so sorgen, sodass im Notfall der Türflügel von Hand von der Geschlossenstellung in die Offenstellung überführt werden kann.The object of the invention is based, in a door drive arranged in the rotary column drive motor with a downstream planetary gear in a simple manner for a Unlock so ensure that in case of emergency, the door can be transferred by hand from the closed position to the open position.

Diese Aufgabe wird durch die im Anspruch 1 genannten Merkmale gelöst.This object is achieved by the features mentioned in claim 1.

Zur Untersetzung der Drehbewegung des Elektromotors in der Drehsäule ist mindestens eine Planetengetriebestufe vorgesehen. Durch die mindestens eine Planetengetriebestufe erfolgt, wie bereits ausgeführt, eine Untersetzung der Drehzahl des Motors mit der Folge, dass hierbei das Drehmoment zunimmt. Hierdurch wird erreicht, dass verhältnismäßig kleine Motoren zum Einsatz gelangen können, wobei darüber hinaus in Abhängigkeit von der Anzahl der eingesetzten Planetengetriebestufen auch eine derartige Selbsthemmung des Türantriebs erreicht werden kann, dass gesonderte Maßnahmen, um ein unbeabsichtigtes Öffnen der Tür, bei z. B. Erschütterungen während der Fahrt, vermieden werden können.To reduce the rotational movement of the electric motor in the rotary column at least one planetary gear stage is provided. By the at least one planetary gear stage takes place, as already stated, a reduction of the speed of the motor, with the result that in this case the torque increases. This ensures that relatively small motors can be used, in addition, depending on the number of planetary gear stages used and such self-locking of the door drive can be achieved that separate measures to prevent inadvertent opening of the door at z. B. vibrations while driving, can be avoided.

Wie bereits oben ausgeführt, weist der Planetenträger der mindestens einen Planetengetriebestufe ein Drehglied, in Form eines Ritzels, auf, das festlegbar ist. Ist das Ritzel nicht festgelegt, kann sich somit der Planetenträger der mindestens einen Planetengetriebestufe frei drehen. Das bedeutet, dass die am Planetenträger angeordneten Planeten um das Sonnenrad, das an der Antriebswelle des Elektromotors angeordnet ist, ebenfalls frei drehen. Im Bereich der Planeten der Planetengetriebestufe ist die Drehsäule mit einer Innenverzahnung versehen. Wird nun das Ritzel festgesetzt, dann ist naturgemäß die Drehbewegung des Planetenträgers unterbunden. Das bedeutet, dass bei Betrieb des Motors, da das Sonnenrad blockiert ist, mithin die Antriebswelle des Motors blockiert ist, über die Verbindung des Motorgehäuses mit dem Innenmantel der Drehsäule die Drehsäule selbst in Rotation versetzt wird. Durch den an der Drehsäule angeordneten, mindestens einen Arm, durch den die Drehsäule mit dem Türflügel in Verbindung steht, erfolgt dann eine Schwenkbewegung des Türflügels. Ist das Drehglied nicht festgelegt, dann dreht die Drehsäule frei, mithin ist im Notfall der Türflügel von Hand von der Geschlossenstellung in Offenstellung zu überführen.As already stated above, the planet carrier of the at least one planetary gear stage, a rotary member, in the form of a pinion, which can be fixed. If the pinion is not fixed, the planet carrier of the at least one planetary gear stage can thus rotate freely. This means that the planets arranged on the planet carrier also rotate freely about the sun gear which is arranged on the drive shaft of the electric motor. In the area of the planets of the planetary gear stage, the rotary column is provided with an internal toothing. Now, if the pinion set, then of course the rotational movement of the planet carrier is suppressed. This means that during operation of the engine, since the sun gear is blocked, thus the drive shaft of the motor is blocked, the rotary column itself is set in rotation via the connection of the motor housing with the inner jacket of the rotary column. By arranged on the rotary column, at least one arm through which the rotary column is in communication with the door, then takes place a pivoting movement of the door leaf. If the rotary member is not fixed, then the rotary column rotates freely, therefore, in case of emergency, the door leaf is to be transferred by hand from the closed position to the open position.

Des Weiteren ist zur Festlegung des Ritzels, eine Arretiereinrichtung vorgesehen. Die Arretiereinrichtung ist insbesondere im oberen Bereich des Türportals vorgesehen, wobei die Arretiereinrichtung im Einzelnen einen um eine Achse drehbar gelagerten Schwenkhebel umfasst, der ein Feststellglied aufweist, das in Eingriff mit dem Drehglied bringbar ist. Hierbei weist das Feststellglied insbesondere eine Verzahnung auf, da das Drehglied als Ritzel ausgebildet ist. Insofern ist das Feststellglied an dem Schwenkhebel unverdrehbar angeordnet.Furthermore, a locking device is provided for fixing the pinion. The locking device is provided in particular in the upper region of the door portal, wherein the locking device comprises in detail a pivotable about an axis pivoting lever which has a locking member which can be brought into engagement with the rotary member. In this case, the locking member in particular has a toothing, since the rotary member is designed as a pinion. In this respect, the locking member is arranged non-rotatably on the pivot lever.

Zur Betätigung des Schwenkhebels ist eine Hebelanordnung vorgesehen. Der Schwenkhebel ist in der Draufsicht in etwa U-förmig ausgebildet, wobei der Schwenkhebel im Bereich des Endes seines einen Schenkels durch eine Achse in einem Gehäuse schwenkbar gelagert ist, wobei im Bereich des Endes des anderen Schenkels die Hebelanordnung angeordnet ist, um den Schwenkhebel mit dem Feststellglied in oder außer Eingriff mit dem Drehglied zu bringen. Hierbei umfasst die Hebelanordnung einen abgewinkelten Hebel, der ebenfalls im Gehäuse schwenkbar gelagert ist. Dieser abgewinkelte Hebel steht mit einem weiteren Hebel, dem sogenannten Betätigungshebel, schwenkbar in Verbindung, wobei bei Betätigung dieses Betätigungshebels durch den abgewinkelten Hebel der Schwenkhebel, wie bereits ausgeführt, mit dem an ihm angeordneten Feststellglied, insbesondere mit einer Verzahnung in oder außer Eingriff mit dem Ritzel, bringbar ist. Der Betätigungshebel ist schwenkbar im Gehäuse gelagert. Das Gehäuse zur Aufnahme der Arretiereinrichtung ist hierbei, wie bereits ausgeführt, im Kopfbereich der Drehsäule im Bereich der Lagerung der Drehsäule im Türportal angeordnet. Der Betätigungshebel selbst ragt aus dem Gehäuse heraus und ist insofern von außen zu betätigen.For actuating the pivot lever, a lever arrangement is provided. The pivot lever is formed in the plan view in approximately U-shaped, wherein the pivot lever is pivotally mounted in the region of the end of its one leg by an axle in a housing, wherein in the region of the end of the other leg, the lever arrangement is arranged to bring the pivot lever with the locking member in or out of engagement with the rotary member. Here, the lever arrangement comprises an angled lever, which is also pivotally mounted in the housing. This angled lever is pivotally connected to a further lever, the so-called actuating lever, wherein upon actuation of this actuating lever by the angled lever of the pivot lever, as already stated, with the locking member arranged on it, in particular with a toothing in or out of engagement with the Pinion, can be brought. The operating lever is pivotally mounted in the housing. The housing for receiving the locking device is in this case, as already stated, arranged in the head region of the rotary column in the region of the mounting of the rotary column in the door portal. The operating lever itself protrudes from the housing and is therefore to be operated from the outside.

Bei der Darstellung gemäß Fig. 1 ist das Türportal mit 1 bezeichnet. In dem Türportal 1 befindet sich die mit 10 bezeichnete Drehsäule. Die Drehsäule 10 weist beabstandet zueinander zwei Schwenkarme 12 auf, durch die die Drehsäule 10 mit dem Türflügel 13 in Verbindung steht. Darüber hinaus ist an dem Türflügel 13 in Verbindung zum Türportal 1 ein Führungsarm 14 angeordnet. Die Drehsäule 10 ist am unteren Ende (Pfeil 15) drehbar im Portal 1 gelagert. Am oberen Ende der Drehsäule 10 befindet sich ein weiteres Lager 16, wodurch die Drehsäule 10 am oberen Ende ebenfalls drehbar in dem Türportal 1 gelagert ist. Wie sich aus der Darstellung gemäß Fig. 2 ergibt, weist die Drehsäule 10 den Elektromotor 21 auf. Der Elektromotor 21 ist über sein Gehäuse fest mit der Innenmantelfläche der Drehsäule 10 verbunden. Dem Motor 21 nachgeordnet sind drei Planetengetriebestufen 30, 30a, 30b, die für eine Untersetzung der Motorwelle 31 sorgen. Hierzu besitzt die Motorwelle 31 am oberen Ende ein Sonnenrad 32, wobei auf dem Sonnenrad 32 mindestens drei Planetenräder 33 kämmen, die durch den Planetenträger 34 gehalten sind. Die Drehsäule 10 besitzt innen im Bereich der Planetenräder 33 eine Innenverzahnung 35 und fungiert somit als Hohlrad, sodass die Planeten 33 auf der Innenverzahnung 35 kämmen. Die weiteren Planetenstufen 30, 30a, 30b sorgen für eine weitere Untersetzung der Drehzahl der Welle 31. Der Aufbau der beiden nachfolgenden Planetengetriebestufen 30a, 30b ist identisch mit der zuvor beschriebenen Planetenstufe 30, weshalb die Bezugszeichen gleich, bis auf die Buchstaben a und b, gewählt wurden. Von dem Planetenträger 34b geht ein weiteres Sonnenrad 38 ab, das als freies Drehglied ausgebildet ist. Dieses Drehglied 38 ist durch das Feststellglied 39 festlegbar. Das Feststellglied 39 ist Teil einer Arretiereinrichtung 40, deren wesentlicher Bestandteil ein Schwenkhebel 41 ist, wobei der Schwenkhebel 41 das Feststellglied 39 aufweist. Bei Verschwenkung des Schwenkhebels 41 wird das Feststellglied 39, das insbesondere eine Verzahnung aufweist, in Eingriff mit dem Drehglied 38, das als Ritzel ausgebildet ist, gebracht. Wird das Drehglied 38 durch das Feststellglied 39 arretiert, dann sind die nachfolgenden Planetenträger 34b, 34a, und 34 in ihrer Drehung blockiert. Die Folge hiervon ist, dass bei Betrieb des Motors 21 die Motorwelle 31 ebenfalls festgehalten ist, weshalb der Motor 21 über sein Gehäuse die Drehsäule 10 in Rotation versetzt und insofern für ein Verschwenken des Türflügels 13 sorgt.In the presentation according to Fig. 1 is the door portal marked 1. In the door portal 1 is the designated 10 rotary column. The rotary column 10 has spaced apart from each other two pivot arms 12, through which the rotary column 10 is in communication with the door leaf 13. In addition, a guide arm 14 is arranged on the door leaf 13 in connection with the door portal 1. The rotary column 10 is rotatably mounted in the portal 1 at the lower end (arrow 15). At the upper end of the rotary column 10 is another bearing 16, whereby the rotary column 10 is also rotatably mounted in the door portal 1 at the upper end. As can be seen from the illustration according to Fig. 2 results, the rotary column 10, the electric motor 21. The electric motor 21 is connected via its housing fixed to the inner circumferential surface of the rotary column 10. Downstream of the motor 21 are three planetary gear stages 30, 30 a, 30 b, which provide for a reduction of the motor shaft 31. For this purpose, the motor shaft 31 has at the upper end a sun gear 32, wherein on the sun gear 32 at least three planet gears 33 mesh, which are held by the planet carrier 34. The rotary column 10 has inside of the planetary gears 33 an internal toothing 35 and thus acts as a ring gear, so that the planetary gears 33 mesh on the internal teeth 35. The further planetary stages 30, 30a, 30b provide for a further reduction of the rotational speed of the shaft 31. The structure of the two following planetary gear stages 30a, 30b is identical to the previously described planetary stage 30, which is why the reference numerals are the same except for the letters a and b, were chosen. From the planet carrier 34b is another sun gear 38, which is designed as a free rotary member. This rotary member 38 can be fixed by the locking member 39. The locking member 39 is part of a locking device 40, whose essential part is a pivot lever 41, wherein the pivot lever 41, the locking member 39 has. When pivoting the pivot lever 41, the locking member 39, which in particular has a toothing, in engagement with the rotary member 38 which is formed as a pinion, brought. Will the rotary member 38 locked by the locking member 39, then the following planet carrier 34 b, 34 a, and 34 are blocked in their rotation. The consequence of this is that during operation of the motor 21, the motor shaft 31 is also held, so the motor 21 via its housing, the rotary column 10 is set in rotation and thus provides for pivoting of the door leaf 13.

Befindet sich das Feststellglied 39 nicht in Eingriff mit dem Drehglied 38, dann kann der Türflügel per Hand in Offenstellung gebracht werden. Die Ausbildung der Arretiereinrichtung ergibt sich im Einzelnen aus den Figuren 3 und 4. Die Arretiereinrichtung 40 befindet sich in einem Gehäuse 50, das am oberen Ende der Drehsäule an dem Portal 1 angeordnet ist. Der mit 41 bezeichnete Schwenkhebel steht durch eine Achse 43 mit dem Gehäuse 50 in schwenkbarer Verbindung. Der Schwenkhebel 41 besitzt das Feststellglied 39, wobei das Feststellglied 39 im vorliegenden Fall mit einer Verzahnung ersehen ist. Das Feststellglied 39 ist mit dem Drehglied 38 in Eingriff bringbar, das die Funktion eines Sonnenrades hat, wie sich dies in Anschauung von Fig. 2 ergibt. Dieses Sonnenrad oder Drehglied 38 steht in starrer Verbindung mit dem Planetenträger 34b, so dass dann, wenn das Feststellglied 39 durch den Schwenkhebel 41 in Eingriff mit dem Ritzel 38 gebracht wird, das Ritzel oder Drehglied 38 fest gehalten, also undrehbar, ist. Zum Verschwenken des Schwenkhebels 41 ist ein Winkelhebel 48 vorgesehen, der drehbar auf dem Schwenkhebel 41 durch die Achse 48a gelagert ist. Am Ende des Winkelhebels 48 befindet sich der Betätigungshebel 49, der im Gehäuse durch die Achse 49a schwenkbar gelagert ist. Erkennbar ist, dass bei Verschwenkung des Betätigungshebels 49 in Richtung des Pfeils 60 das Feststellglied 39 außer Eingriff mit dem Ritzel 38 bringbar ist.If the locking member 39 is not in engagement with the rotary member 38, then the door leaf can be brought by hand in the open position. The formation of the locking device results in detail from the FIGS. 3 and 4 , The locking device 40 is located in a housing 50 which is arranged at the upper end of the rotary column on the portal 1. The designated pivot lever 41 is connected by an axis 43 with the housing 50 in a pivotal connection. The pivot lever 41 has the locking member 39, wherein the locking member 39 is seen in the present case with a toothing. The locking member 39 is engageable with the rotary member 38, which has the function of a sun gear, as in the view of Fig. 2 results. This sun gear or rotary member 38 is in rigid connection with the planet carrier 34b, so that when the locking member 39 is brought by the pivot lever 41 into engagement with the pinion 38, the pinion or rotary member 38 is held firmly, that is non-rotatable. For pivoting the pivot lever 41, an angle lever 48 is provided which is rotatably mounted on the pivot lever 41 by the axis 48 a. At the end of the angle lever 48 is the actuating lever 49 which is pivotally mounted in the housing 49a by the axis. It can be seen that upon pivoting of the actuating lever 49 in the direction of the arrow 60, the locking member 39 can be brought out of engagement with the pinion 38.
