Aus der EP 0 405 059 A1 ist ein Torblatt mit einem Torantriebsmotoraggregat bekannt, zwischen dessen Abtriebswelle und einer zur Betätigung und/oder Halterung des Torblattes vorgesehenen Torwelle als Torantriebsdrehmomentübertragungsvorrichtung ein Zugmittelübersetzungsgetriebe mit einer Getriebeeingangswelle als Antriebsglied und einer Getriebeausgangswelle als Abtriebsglied geschaltet ist. Die beiden Glieder sind in einer durch ein Getriebegehäuse gebildeten Lagereinrichtung gelagert, das aus zwei identisch aufgebauten ortsfest zueinander verbundenen Halbschalen gebildet ist und das Zugmittelgetriebe umgibt. Das Getriebegehäuse und damit das Gesamtgetriebe ist insgesamt senkrecht zu den parallelen Drehachsen der Getriebewellen - Getriebeeingangs- und -ausgangswelle - um die Achse der Torwelle drehbar gelagert und durch Reaktionskraft des zu betätigenden Torblattes gegen ein Dämpfungsglied und/oder ein elastisches Element in Form einer Feder verschwenkbar. Das Torantriebsmotoraggregat wiederum ist von der Getriebeeingangswelle getragen und damit an das Gehäuse angeschlossen. Bei Anlauf des Torantriebsmotoraggregats ergibt sich eine stoßartige Kraft (Torsionsstoß), die durch die Verschwenkbewegung der bekannten Torantriebsdrehmomentübertragungsvorrichtung insgesamt gegen das elastische Element gedämpft aufgenommen wird.

The door drive motor unit is in turn carried by the transmission input shaft and thus connected to the housing. at Starting up the door drive motor unit results in a shock-like force (torsional impact) that by the pivoting movement of the known door drive torque transmission device is absorbed damped overall against the elastic element. This Swiveling movement is also used for an overload shutdown.

Die eingangs erwähnte WO 94/00665 schlägt ausgehend vom Stand der Technik nach der EP 0 405 059 A1 zur Verbesserung desselben eine Torantriebsdrehmomentübertragungsvorrichtung der im Oberbegriff des Anspruchs 1 erwähnten Art vor. Diese bekannte Torantriebsdrehmomentübertragungsvorrichtung ist gemäß WO 94/00665 als Zugmittelgetriebe und Teil einer Torantriebsvorrichtung für ein Torblatt ausgebildet, das eine mit dem Torblatt getrieblich verbundene Torwelle aufweist, an die die Abtriebswelle des in einem Antriebsgehäuse aufgenommenen Torantriebsmotoraggregats unter Zwischenschaltung des in einem Getriebegehäuse aufgenommenen Zugmittelgetriebes angeschlossen ist. Die bekannte Torantriebsdrehmomentübertragungsvorrichtung weist als Antriebsglied eine mit der Abtriebswelle des Torantriebsmotoraggregates verbundene Eingangswelle und als Abtriebsglied eine mit der Torwelle verbundene Ausgangswelle auf, wobei die Drehachsen von Ein- und Ausgangswelle voneinander um ein Vielfaches der Halbmesser von sich auf den Wellen befindlichen durch das Zugmittel getrieblich verbundenen Getrieberädern beabstandet sind. Dabei ist das Antriebsgehäuse des Torantriebsmotoraggregates ortsfest gehalten und mit dem Getriebegehäuse und damit der Torantriebsdrehmomentübertragungsvorrichtung insgesamt verdrehfest derart verbunden, dass Drehmomente zwischen der Torwelle und der Abtriebswelle des Torantriebsmotoraggregates nach Art eines starren Hebels aufgenommen sind.The WO 94/00665 mentioned at the beginning looks up on the basis of the prior art EP 0 405 059 A1 to improve the same a door drive torque transmission device the type mentioned in the preamble of claim 1. This well-known Door drive torque transmission device is according to WO 94/00665 as a traction mechanism and formed part of a door drive device for a door leaf, the one with the door leaf has a gear shaft connected to the output shaft of the in a Drive housing accommodated door drive motor unit with intermediate connection of the traction mechanism gearbox accommodated in a gearbox housing is. The known door drive torque transmission device has as a drive member an input shaft connected to the output shaft of the door drive motor unit and an output shaft connected to the gate shaft as an output member, the Axes of rotation of input and output shaft from each other by a multiple of the radius of gear wheels which are located on the shafts and are connected by the traction mechanism are spaced. The drive housing of the door drive motor unit held stationary and with the gear housing and thus the door drive torque transmission device overall connected in a torsion-proof manner such that torques between the door shaft and the output shaft of the door drive motor unit according to Art a rigid lever are included.

Aufgabe der Erfindung ist es, eine Torantriebsdrehmomentübertragungsvorrichtung der im Oberbegriff des Anspruchs 1 genannten Art, eine damit versehene motorische Torantriebsvorrichtung der im Oberbegriff des Anspruchs 10 genannten Art sowie ein damit versehenes Tor der im Oberbegriff des Anspruchs 12 genannten Art hinsichtlich Laufruhe, Lebensdauer und Reparaturbedürftigkeit zu verbessern.The object of the invention is to provide a door drive torque transmission device in Preamble of claim 1 mentioned type, a motorized door drive device provided with it the type mentioned in the preamble of claim 10 and provided with it Gate of the type mentioned in the preamble of claim 12 with regard to smooth running, Improve service life and need for repair.

Diese Aufgabe wird durch eine Torantriebsdrehmomentübertragungsvorrichtung nach Anspruch 1, eine motorische Torantriebsvorrichtung nach Anspruch 10 bzw. ein Tor nach Anspruch 12 gelöst.This object is achieved by a door drive torque transmission device according to claim 1, a motorized gate drive device according to claim 10 or a gate Claim 12 solved.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Erfindungsgemäß ist also anstelle eines starren Drehmomentübertragungsgehäuses, das Drehmomente nach Art eines starren Hebels überträgt, eine Lagereinrichtung mit zwei getrennt ausgeführten Lagerteilen vorgesehen, eines für das Antriebsglied und eines für das Abtriebsglied der Torantriebsdrehmomentübertragungsvorrichtung, die nicht starr, sondem elastisch miteinander derart verbunden sind, dass Torsionsstöße oder -Schwingungen zwischen den Antriebs- und Abtriebsglied gedämpft übertragen werden. Hierzu sind die beiden Glieder bevorzugt in der Drehebene wenigstens eines der beiden Glieder derart elastisch miteinander verbunden, dass sie zumindest im geringen Umfang (einige Millimeter, beispielsweise ca. 0,5 bis 5 mm Millimeter oder einige Winkelgrade) relativ zueinander bewegbar und insbesondere verschwenkbar sind.According to the invention, instead of a rigid torque transmission housing, the Torques transmitted in the manner of a rigid lever, a bearing device with two separately executed bearing parts provided, one for the drive member and one for the Output member of the door drive torque transmission device, which is not rigid, but are elastically connected to one another in such a way that torsional shocks or vibrations are transmitted damped between the drive and output member. For this are the two links preferably in the rotational plane at least one of the two links in this way elastically connected to each other so that they are at least to a small extent (a few millimeters, for example, about 0.5 to 5 mm millimeters or a few degrees) relative to each other are movable and in particular pivotable.

Bei der in der WO 94/00665 gerade als vorteilhaft angesehenen Drehmomentaufnahme nach Art eines starren Hebels sind zwar die auf bei Torsionsstößen auf das Torantriebsmotoraggregat und dessen Halterung ausgeübten Stoßkräfte aufgrund der Übertragung über einen langen Hebel gering. Die Stöße müssen dabei aber durch den gesamten Drehmomentübertragungsstrang aufgenommen werden, was schon zu einzelnen Brüchen des jeweils schwächsten Elements darin, wie beispielsweise der Wellenkupplung zwischen Torantriebsdrehmomentübertragungsvorrichtung und der Torwelle geführt hat, das somit ersetzt werden musste. Auch ist die Laufruhe bei der erfindungsgemäßen Torantriebsdrehmomentübertragungsvorrichtung gegenüber dieser bekannten Torantriebsdrehmomentübertragungsvorrichtung in der Praxis nicht nur beim Anfahren mit dem dadurch bedingten Torsionsstoß sondern auch während der Torblattbewegung wesentlich verbessert. Die in der Praxis vorhandenen Torwellen laufen nämlich praktisch nie rund, da sie einerseits naturgemäß wegen des Angriffs der Torsionsfeder oder des Rolltorpanzers oder dergleichen Anbauten wesentliche Unwuchten aufweisen, andererseits die daran angreifenden Kräfte sich bereits im Laufe einer Wellenumdrehung ständig ändern. Zudem gibt es durchaus in der Praxis auch stärker verbogene Torwellen. All dies führt zu mehr oder weniger starken Schwingungen in Umfangs- und Radialrichtung, die erfindungsgemäß mit relativ geringen ungefederten Massen (nur das Abtriebsgliedlagerteil ist den Torsionsstößen der Torwelle mehr oder weniger ungefedert ausgesetzt) aufgefangen und über die elastische Verbindung allenfalls gedämpft auf das Antriebsgliedlagerteil und damit auf das Torantriebsmotoraggregat übertragen werden.In the case of torque absorption, which is just regarded as advantageous in WO 94/00665 in the manner of a rigid lever, those are in the event of torsional impacts on the door drive motor unit and its holder applied impact forces due to the transmission low over a long lever. But the bumps must go through the whole Torque transmission line are included, which leads to individual breaks of the weakest element in each, such as the shaft coupling between Gate drive torque transmission device and the gate shaft has led thus had to be replaced. The smoothness of the door drive torque transmission device according to the invention is also smooth compared to this known door drive torque transmission device in practice not only when starting up with it conditional torsion shock but also significantly during the door leaf movement improved. The gate shafts available in practice practically never run smoothly there on the one hand, of course, because of the attack by the torsion spring or the roller shutter curtain or similar attachments have significant imbalances, on the other hand, those on them attacking forces change constantly in the course of a shaft revolution. moreover there are definitely more bent gate waves in practice. All of this leads to more or less severe vibrations in the circumferential and radial directions, the invention with relatively low unsprung masses (only the output member bearing part is the torsional impact exposed to the gate shaft more or less unsprung) and At most damped on the drive link bearing part and thus via the elastic connection be transferred to the door drive motor unit.

Bei auftretenden Torsionsstößen wird also nicht die gesamte aus Torantriebsmotoraggregat und Torantriebsdrehmomentübertragungsvorrichtung gebildete Torantriebsvorrichtung elastisch verschwenkt wie im Stand der Technik nach der EP 0 405 059 A1, sondern nur die beiden Lagerteile zueinander, so dass Nachteile der aus der EP 0 405 059 A1 bekannten Torantriebsdrehmomentübertragungsvorrichtung, die insbesondere in einer schwierigeren und aufwendigeren Herstellung und Montage der damit versehenen Torantriebsvorrichtung insgesamt liegen, vermeidbar sind. Auch sind die bei Torsionsstößen auftretenden ungefederten Massen gegenüber diesem Stand der Technik wesentlich verringert, was einerseits wesentlich zur Laufruhe beiträgt, andererseits aber hilft, durch die Stöße auf das Torantriebsmotoraggregat bedingte Beschädigungen zu verhindern. Die Erfindung vereint also die Vorteile der bekannten Torantriebsdrehmomentübertragungsvorrichtungen, ohne deren Nachteile aufzuweisen.In the event of torsional impacts, not all of the door drive motor assembly and gate drive torque transmission device formed gate drive device elastically pivoted as in the prior art according to EP 0 405 059 A1, but only the two bearing parts to each other, so that disadvantages of those known from EP 0 405 059 A1 Gate drive torque transmission device, in particular in a more difficult and complex production and assembly of the door drive device provided with it overall, are avoidable. They are also with torsion bumps occurring unsprung masses significantly reduced compared to this prior art, which on the one hand contributes significantly to smooth running, but on the other hand helps with the To prevent impacts on the door drive motor unit caused damage. The invention thus combines the advantages of the known door drive torque transmission devices, without showing their disadvantages.

Gemäß einer vorteilhaften Ausgestaltung der Erfindung sind die beiden Lagerteile in wählbarem Abstand zueinander elastisch miteinander verbindbar, so dass die Torantriebsdrehmomentübertragungsvorrichtung an verschiedene zu überbrückende Abstände zwischen dem Torantriebsmotoraggregat und der Torwelle anpassbar ist und größere Freiheiten zur Montage des Torantriebsmotoraggregats bestehen.According to an advantageous embodiment of the invention, the two bearing parts are in Selectable distance to each other elastically connectable, so that the door drive torque transmission device to different distances to be bridged is adjustable between the door drive motor unit and the door shaft and larger Freedom to assemble the door drive motor unit exist.

Wenn die beiden Lagerteile (5, 6) wenigstens in einer senkrecht zu wenigstens einer der beiden Drehachsen, insbesondere der Drehachse des Abtriebsgliedes, verlaufenden Ebene zueinander abwinkelbar oder verschwenkbar elastisch miteinander verbunden sind., lassen sich Torsionsschwingungen um diese Drehachse durch elastische Relativverschwenkung dämpfen. Eine eine Relativverschwenkung zulassende elastische Verbindung lässt sich auf verschiedene Weise erreichen. Beispielsweise könnten die beiden Lagerteile über eine Achse oder ein Gelenk (auch Kugelgelenk) zueinander schwenkbar verbunden sein, welche Verschwenkung gegen irgendeine Art von elastischem Element wie Druck- oder Zugfeder, Gummiblock, Drehstab, Torslonsfeder oder dergleichen erfolgt. Wenn aber die beiden Lagerteile Ober wenigstens zwei voneinander beabstandete Verbindungspunkte elastisch miteinander verbunden sind, so lässt sich damit nicht nur eine umfangsmäßige Schwingung um eine Drehachse dämpfen, zusätzlich können sich die Lagerteile auch translatorisch zueinander gegen die elastische Verbindung in den Verbindungspunkten gedämpft bewegen, obwohl die Verbindung durch die zwei beabstandeten Verbindungspunkte steif genug auslegbar ist, um die geforderten Drehmomente auch tatsächlich übertragen zu können. Somit lassen sich z.B. auch Stöße und Schwingungen radial zu einer Drehachse, die beispielsweise durch ein "Eiern" der Torwelle entstehen, dämpfen. Mehrere voneinander beabstandete Verbindungspunkte lassen sich beispielsweise durch ein ausgedehntes elastisches Verbindungselement, beispielsweise einen Gummistreifen, über den die Lagerteile miteinander in flächigem oder linienartigen Eingriff sind, realisieren. Bevorzugt ist jedoch, dass die beiden Verbindungspunkte durch zwei voneinander beabstandet angeordnete Verbindungsblöcke oder Verbindungsbuchsen aus elastischem Material gebildet werden, über die die beiden Lagerteile miteinander verbunden sind. Eines der beiden Lagerteile kann dabei z.B. mit in als Verbindungsbuchsen verwendete Gummibuchsen eingreifenden Bolzen, das andere mit die Gummibuchsen umgebenden oder umfassenden z.B. rohrförmigen Einfassungen versehen sein. Die Steifheit und die Dämpfungscharakteristiken lassen sich dabei - auch richtungsabhängig - durch Lage, Ausrichtung und Anordnung der Verbindungsbuchsen - auch relativ zueinander - und durch Auswahl der Abmessungen sowie des Materials der Verbindungsbuchsen (beispielsweise Gummibuchsen mit verschiedenen Shore-Härten und/oder Durchmessern) wählbar beeinflussen. So ist eine vorteilhafte Ausgestaltung der Erfindung gekennzeichnet durch ein Sortiment von elastischen Verbindungselementen zum Verbinden der beiden Lagerteile mit verschiedenen, insbesondere durch verschiedene Härten und/oder Abmessungen wie Außendurchmessem erzielten, elastischen Eigenschaften, aus welchem Sortiment gezielt zur Einstellung der Steifigkeit und/oder der Torsionsschwingungsdämpfungscharakteristik Verbindungselemente zur Verwendung in der Lagereinrichtung auswählbar sind.If the two bearing parts (5, 6) at least in one perpendicular to at least one of the two axes of rotation, in particular the axis of rotation of the output member, extending plane are elastically connected to one another such that they can be angled or pivoted. torsional vibrations around this axis of rotation can be achieved by elastic relative pivoting dampen. An elastic connection that allows relative pivoting can be achieved in different ways. For example, the two bearing parts pivotally connected to one another via an axis or a joint (also a ball joint) be what pivoting against some kind of elastic element like Compression or tension spring, rubber block, torsion bar, torsion spring or the like. But if the two bearing parts above at least two spaced connection points are elastically connected to one another, so that not only one dampen circumferential vibration around an axis of rotation, additionally Bearing parts also translationally to each other against the elastic connection in the connection points dampened move, though the connection through the two spaced Connection points can be designed stiff enough to the required torques to actually be able to transmit. Thus, e.g. also shocks and vibrations radial to an axis of rotation, which is caused, for example, by "egg" of the door shaft, dampen. Multiple connection points spaced apart from each other can be for example by an extensive elastic connecting element, for example a rubber strip, over which the bearing parts with each other in flat or line-like Are intervention. However, it is preferred that the two connection points pass through two spaced apart connection blocks or connection sockets are formed from elastic material, via which the two bearing parts together are connected. One of the two bearing parts can e.g. with in as connection sockets used rubber bushes engaging bolts, the other with the rubber bushings surrounding or extensive e.g. be provided with tubular edging. The Stiffness and the damping characteristics can be - depending on the direction - By position, orientation and arrangement of the connection sockets - also relative to each other - And by selecting the dimensions and the material of the connecting bushes (for example rubber bushes with different Shore hardness and / or diameters) selectively influence. An advantageous embodiment of the invention is characterized in this way through an assortment of elastic connecting elements for connecting of the two bearing parts with different, in particular through different hardnesses and / or dimensions such as elastic properties achieved outside diameter, from which range specifically for setting the stiffness and / or the torsional vibration damping characteristics Fasteners for use in storage facilities are selectable.

Die Lagerteile können verschieden aufgebaut sein, sofern sie nur zum Lagern der Glieder und zur Verbindung miteinander in der Art, dass Torsionsstößen und sonstigen Stößen bzw. Schwingungen im Antriebsstrang absorbierbar sind, geeignet sind. Demgemäß könnten sie z.B. auch durch plattenartige Stanzteile oder durch Profilteile usw. mit einem Lagerbereich und einem Verbindungsbereich gebildet sein, wobei die getriebliche Verbindung zwischen den Gliedern durch eine zusätzliche z.B. auch mehrteilige Abdeckung z.B. aus Kunststoff abgedeckt werden könnte. Eine zusätzliche Abdeckung ist vermeidbar, wenn die beiden Lagerteile miteinander elastisch gekoppelte, insbesondere teleskopartig vorzugsweise mit Spiel ineinandergreifende, Einzelteile eines Drehmomentübertragungsgehäuses sind, vorzugsweise dergestalt, dass die Einzelteile jeweils im wesentlichen aus zwei, insbesondere identischen, miteinander verbundenen Gehäuseschalen gebildet sind.The bearing parts can be constructed differently, provided that they are only for storing the links and to connect with each other in such a way that torsional shocks and other shocks or vibrations in the drive train are absorbable, are suitable. Accordingly, could you e.g. also by plate-like stamped parts or by profile parts etc. with one Be formed storage area and a connection area, the gear connection between the limbs by an additional e.g. also multi-part cover e.g. could be covered from plastic. Additional coverage is avoidable if the two bearing parts are elastically coupled to one another, in particular telescopically preferably with interlocking, individual parts of a torque transmission housing are, preferably such that the individual parts are each essentially made of two, in particular identical, interconnected housing shells are formed.

Auch die getriebliche Verbindung kann verschiedener Gestalt sein; auch möglich wäre ein Zahnradgetriebe, eine Kardanwelle oder dergleichen. Die größten Freiheitsgrade in bezug auf die zu überbrückenden Abmaße sowie die Bewegungsmöglichkeiten der Lagerteile zur Dämpfung bietet eine wie im Prinzip auch aus dem eingangs erwähnten Stand der Technik bekannte Ausbildung, bei der die getriebliche Verbindung durch wenigstens ein Endlos-Zugmittel wie Kette, Zahngurt oder Riemen gebildet ist und jedes der beiden Glieder ein Zugmittelrad aufweist, das mit dem wenigstens einen Zugmittel in form- oder reibschlüssigen Eingriff ist. Dabei ist weiter bevorzugt, dass ein durch das wenigstens eine Zugmittel und die Zugmittelräder gebildetes Zugmittelgetriebe von den Gehäuseschalen der Einzelteile des Drehmomentübertragungsgehäuses umgeben ist, wobei insbesondere eine die beiden Trume des Zugmittels elastisch zueinander ziehende Zugmittelspannvorrichtung innerhalb des Drehmomentübertragungsgehäuses vorgesehen ist. The gear connection can also take various forms; a would also be possible Gear transmission, a cardan shaft or the like. The greatest degrees of freedom in relation on the dimensions to be bridged and the possibilities of movement of the bearing parts for damping offers as in principle also from the aforementioned state of the Technology known training in which the gear connection by at least one Endless traction means such as a chain, tooth belt or belt is formed and each of the two links has a traction wheel, which is in positive or frictional engagement with the at least one traction means Intervention is. It is further preferred that one by the at least one Traction means and the traction mechanism gears formed by the housing shells the individual parts of the torque transmission housing is surrounded, in particular a traction device tensioning device which pulls the two strands of the traction device elastically to one another is provided within the torque transmission housing.

Bei einer vorteilhaften Ausgestaltung der erfindungsgemäßen Torantriebsvorrichtung ist vorgesehen, dass das Antriebsgliedlagerteil mit einem ortsfest angeordneten Antriebsgehäuses des Torantriebsmotoraggregats, insbesondere in wählbarer Ausrichtung, fest verbunden ist, das Abtriebsgliedlagerteil aufgrund der elastischen Verbindung der beiden Lagerteile aber von dem Antriebsgehäuse zur Dämpfung von Torsionsschwingungen elastisch entkoppelt ist. Es schwingt also nur das Abtriebsgliedlagerteil mit, wenn Torsionsschwingungen oder Radialschwingungen an der Torwelle auftreten. Das Antriebsgliedlagerteil ist davon entkoppelt und durch die Verbindung mit dem ortsfesten Antriebsgehäuse ortsfest angeordnet. Hierdurch werden Laufgeräusche und die Gefahr von Beschädigungen durch Stöße verringert.In an advantageous embodiment of the door drive device according to the invention provided that the drive member bearing part with a stationary drive housing the door drive motor unit, in particular in a selectable orientation, firmly connected is, the driven member bearing part due to the elastic connection of the two bearing parts but elastic from the drive housing for damping torsional vibrations is decoupled. So it only vibrates the output member bearing part when torsional vibrations or radial vibrations occur on the door shaft. The drive link bearing part is decoupled from it and by the connection to the stationary drive housing arranged stationary. This reduces running noise and the risk of damage reduced by bumps.

Im Prinzip wäre es auch denkbar, anstelle oder zusätzlich zu einer elastischen Verbindung auch eine Verbindung der Lagerteile mit viskoser Dämpfung oder einer Gasdruckdämpfung vorzusehen. Neben einem elastischen Verbindungselement könnte auch ein Reibelement zur Reibdämpfung und/oder ein Flüssigkeitsdämpfer zur Dämpfung von Schwingungen zwischen den Lagerteilen vorgesehen sein. Im Prinzip könnten die beiden Lagerteile oder auch die beiden Glieder der Torantriebsdrehmomentübertragungsvorrichtung durch sämtliche beispielsweise auf dem Gebiet der Torsionsschwingungsdämpfer bei Kraftfahrzeugkupplungen oder bei der Fahrzeugfahrwerken bekannten Dämpfungsprinzipien - Stoßdämpfer, Proportionaldämpfer usw. - miteinander verbunden sein.In principle, it would also be conceivable instead of or in addition to an elastic connection also a connection of the bearing parts with viscous damping or gas pressure damping provided. In addition to an elastic connecting element, a Friction element for friction damping and / or a fluid damper for damping Vibrations can be provided between the bearing parts. In principle, the two could Bearing parts or the two links of the door drive torque transmission device by all, for example, in the field of torsional vibration dampers in motor vehicle clutches or damping principles known in vehicle chassis - Shock absorbers, proportional dampers etc. - be connected to each other.

Die Erfindung betrifft insbesondere eine Torantriebsdrehmomentübertragungsvorrichtung, wie sie aus der WO 94/00665 bekannt ist. Auf diese Druckschrift und auf die EP 0 405 059 A1 wird für weitere hier nicht erläuterte Einzelheiten der Erfindung ausdrücklich verwiesen. Die beschriebene Erfindung baut auf dem Kenntnisstand dieser Druckschriften auf.The invention relates in particular to a door drive torque transmission device, as is known from WO 94/00665. On this document and on EP 0 405 059 A1 is expressly referred to for further details of the invention not explained here. The described invention is based on the state of knowledge of these publications on.

Anstelle eines verdrehfest in Art eines starren Hebels mit dem Antriebsgehäuse verbundenen Übertragungsgehäuse weist die erfindungsgemäße Torantriebsdrehmomentübertragungsvorrichtung vorzugsweise sowohl in Umfangs-- als auch Radialrichtung - eventuell sogar auf die Axialrichtung - in bezug auf die Torwelle gesehen entkoppelte und nur elastisch verbundene Antriebs- und Abtriebsglieder, bspw. in Form von Getriebe- oder Kettenrädern auf. Die Erfindung umfasst also eine elastische Entkopplung zwischen einem Antriebsglied und einem Abtriebsglied der Drehmomentübertragungsvorrichtung in der Art, dass Drehmomente zwischen einer Antriebswelle und einer Abtriebswelle gerade nicht in Art eines starren Hebels, sondern elastisch gedämmt übertragen werden. Hierzu ist zwischen den Lagerungen von Antriebs- und Abtriebsglied eine - auch eine Verdrehung in einer zu den Antriebs- und Abtriebsdrehachsen senkrechten Ebene in bestimmtem Maße zulassende - elastische Verbindung vorgesehen.Instead of a torsionally rigid type connected to the drive housing Transmission housing has the door drive torque transmission device according to the invention preferably in both the circumferential and radial directions - possibly even on the axial direction - seen decoupled with respect to the gate shaft and only elastically connected drive and output elements, for example in the form of gear or Sprockets on. The invention thus includes an elastic decoupling between one Drive member and an output member of the torque transmission device in the way that torque between an input shaft and an output shaft is straight not in the manner of a rigid lever, but rather elastically insulated. For this is between the bearings of the drive and output member - also a rotation in a plane perpendicular to the drive and driven axes of rotation in certain Dimensional - elastic connection provided.

Die Vorteile des somit erfindungsgemäß geschaffenen elastischen Drehmomentübertragungselementes im Vergleich zu dem herkömmlichen starren Drehmomentübertragungselement nach der WO 94/000665 liegen in einer Schonung des Tores und des Antriebsmotoraggregates durch das Abfangen von Stößen und in einem besonders ruhigen Lauf des Tores.The advantages of the elastic torque transmission element thus created according to the invention compared to the conventional rigid torque transmission element according to WO 94/000665 lie in protecting the door and the drive motor unit by intercepting impacts and in a particularly quiet run of the gate.

Die in Fig. 1 dargestellte Torantriebsdrehmomentübertragungsvorrichtung 20 umfasst als Antriebsglied ein Antriebskettenrad 1, ein Zugmittel in Form einer Endtoskette 2 und als Abtriebsglied ein Abtriebskettenrad 3, das durch die Endloskette 2 getrieblich mit dem Antriebskettenrad 1 verbunden ist. Das Antriebskettenrad 1 und das Abtriebskettenrad 3 sind in einer Lagereinrichtung gelagert, die aufgrund ihrer Form und Funktion im folgenden als Kettenknochen 4 bezeichnet wird. Der Kettenknochen 4 bildet eine elastische Verbindung zwischen den beiden Kettenrädern 1 und 3.The door drive torque transmission device 20 shown in FIG. 1 comprises as Drive member a drive sprocket 1, a traction device in the form of an end chain 2 and as Output link an output sprocket 3, which is driven by the endless chain 2 with the drive sprocket 1 is connected. The drive sprocket 1 and the driven sprocket 3 are stored in a storage facility, which due to their shape and function in the following as Chain bone 4 is called. The chain bone 4 forms an elastic connection between the two sprockets 1 and 3.

Der Kettenknochen 4 umfasst zwei Lagerteile zum Lagern der Kettenräder 1 und 3 in Form zweier teleskopartig ineinander geschobener rechteckige Profile, ein hier als Antriebsgliedlagerteil wirkendes Außenprofil 5 und ein hier als Abtriebsgliedlagerteil wirkendes Innenprofil 6. Das Innenprofil 6 ist mit Spiel innerhalb des Außenprofils 5 aufgenommen, so dass die beiden Profile 6 und 5 innerhalb der Kettenebene Ke aus der dargestellten zueinander ausgerichteten Position relativ zueinander in beiden Richtungen durch Drehung um die jeweiligen Drehachsen der Kettenräder 1, 3 abgewinkelt werden können. Auch lässt die elastische Verbindung eine gewisse Relativverschiebung in Richtung der Längsachse L im Sinne eines Ineinanderschiebens oder Auseinanderziehens der beiden Profile 5, 6 zu. Die elastische Verbindung zwischen den beiden Profilen 5 und 6 erfolgt über zwei elastische Verbindungsstellen 7 und 8. Diese Verbindungsstellen 7, 8 weisen jeweils eine mit einem der beiden Profile 5, 6 verbundene Außenbuchse, beispielsweise gebildet durch eine mit dem Innenprofil 6 verbundenes Stahlröhrchen 9, ein mit dem zweiten der beiden Profile verbundenes Eingreifselement, beispielsweise gebildet durch einen mit dem Außenprofil 5 verbundenen Bolzen 10, und ein elastisches Element dazwischen, beispielsweise eine zwischen dem Röhrchen 9 und dem Bolzen 10 vorhandene elastische Verbindungsbuchse in Form einer Gummibuchse 11, auf. Durch die Variierung des elastischen Elements 11 können unterschiedliche Steifigkeiten der elastischen Verbindung in dem Kettenknochen 4 erzielt werden. Dies geschieht beispielsweise durch das Variieren des Außendurchmessers und/oder der Shore-Härte der Gummibuchse 11. Hierzu kann der Monteur und/oder Hersteller der Torantriebsdrehmomentübertragungsvorrichtung 20 aus einem nicht dargestellten Sortiment von Gummibuchsen zwei jeweils geeignete auswählen.The chain bone 4 comprises two bearing parts for supporting the chain wheels 1 and 3 in the form of two telescopically pushed rectangular profiles, an outer profile 5 acting here as a drive link bearing part and an inner profile 6 acting here as a driven member bearing part. The inner profile 6 is accommodated with play within the outer profile 5, so that the two profiles 6 and 5 within the chain plane K e can be angled relative to each other in both directions by rotation about the respective axes of rotation of the chain wheels 1, 3 from the illustrated aligned position. The elastic connection also allows a certain relative displacement in the direction of the longitudinal axis L in the sense of pushing the two profiles 5, 6 apart or pulling them apart. The elastic connection between the two profiles 5 and 6 takes place via two elastic connecting points 7 and 8. These connecting points 7, 8 each have an outer bush connected to one of the two profiles 5, 6, for example formed by a steel tube 9 connected to the inner profile 6, an engaging element connected to the second of the two profiles, for example formed by a bolt 10 connected to the outer profile 5, and an elastic element in between, for example an elastic connecting bushing in the form of a rubber bushing 11 between the tube 9 and the bolt 10. By varying the elastic element 11, different stiffnesses of the elastic connection in the chain bone 4 can be achieved. This is done, for example, by varying the outside diameter and / or the Shore hardness of the rubber bushing 11. For this purpose, the fitter and / or manufacturer of the door drive torque transmission device 20 can select two suitable ones from a range of rubber bushings (not shown).

Eines der beiden Profile, beispielsweise das Außenprofil 5, lässt sich an das später in Bezug auf Fig. 3 näher erläuterte Antriebsgehäuse eines Torantriebsmotoraggregats, beispielsweise eines Getriebemotors, anschließen. Hierzu ist in dem dargestellten Beispiel das Schraubloch 12 vorgesehen. In nicht dargestellten Ausführungsformen sind mehrere jeweils gleich beabstandete Öffnungen im Außen- und Innenprofil 5, 6 vorgesehen, so dass die elastische Verbindung in mehr oder weniger großem Achsabstand von An- und Abtriebsglied stufenweise wählbar erfolgen kann. Die gesamte Torantriebsdrehmomentübertragungsvorrichtung 20 ist weiter mit einem nicht dargestellten Übertragungsgehäuse versehen, welches die Übertragungsvorrichtung gegen Verschmutzung und Eingriff von außen schützt und so Verletzungen verhindert. Dieses Übertragungsgehäuse ist an dem nicht mit dem Antriebsmotor verbundenen Teil 6 des Kettenknochens 4 festgelegt und befestigt. Durch die beschriebene Art der Befestigung des Drehmomentübertragungsgehäuses ist dieses entkoppelt vom Antriebsmotoraggregat. Dadurch lässt sich eine Verstärkung der Motorgeräusche durch ein starr mit dem Antriebsgehäuse verbundenes und somit als Resonanzkörper wirkendes Übertragungsgehäuse verhindern.One of the two profiles, for example the outer profile 5, can be referred to later drive housing of a door drive motor unit, for example a geared motor. This is shown in the example the screw hole 12 is provided. There are several in embodiments not shown provided equally spaced openings in the outer and inner profiles 5, 6, so that the elastic connection with a more or less large center distance from and Output element can be selected in stages. The entire door operator torque transmission device 20 is further with a transmission housing, not shown provided which the transmission device against contamination and interference from protects the outside and thus prevents injuries. This transmission housing is on the Part 6 of the chain bone 4 not connected to the drive motor is fixed and fastened. By the described way of fastening the torque transmission housing this is decoupled from the drive motor unit. This allows for reinforcement the engine noise through a rigidly connected to the drive housing and thus Prevent transmission box acting as a resonance body.

Der Getriebemotor 36 weist ein mit der Zarge 32 ortsfest verbundenes Antriebsgehäuse 37 auf, die Verbindung zwischen Zarge 32 und Antriebsgehäuse 37 ist bei 38 dargestellt. Die zweite Ausführungsform der Torantriebsdrehmomentübertragungsvorrichtung 40 unterscheidet sich von der ersten Ausführungsform 20 nur durch die Art der Verbindung zwischen den Lagerteilen 5 und 6. Für die übrigen Einzelheiten wird auf die obige Beschreibung der ersten Ausführungsform verwiesen, wobei gleiche Bezugsziffern entsprechende Teile kennzeichnen. Die beiden Profile 5 und 6 sind bei der zweiten Ausführungsform der Torantriebsdrehmomentübertragungsvorrichtung 40 nur durch eine einzelne elastische Verbindungsstelle 41 verbunden, die gleich aufgebaut ist, wie die Verbindungsstellen 7 und 8 der ersten Ausführungsform. In Umfangsrichtung zu einer somit durch die Verbindungsstelle 41 geschaffene Schwenkachse 42 sind die beiden Profile 5 und 6 gegen ein nicht dargestelltes elastisches Element in Form einer Druckfeder zwischen den Profilen 5 und 6 oder dergleichen relativ zueinander verschwenkbar. Bei 43 ist noch eine weitere Bohrung zur weiter wählbar möglichen Anordnung des Bolzens 10 der Verbindungsstelle 41 in dem Außenprofil 5 angedeutet. Das Außenprofil 5 ist durch eine Schraubverbindung 44 in passend wählbarer Ausrichtung mit dem Antriebsgehäuse 37 fest verbindbar.The door drive device 34 has a door drive motor unit in the form of a self-locking worm gear, which can be decoupled for emergencies 36 and the gate drive torque transmission device 20 or as shown a second embodiment 40 of a gate drive torque transmission device for the transmission of torques between the geared motor 36 and the Torsion spring shaft 33.

Die dritte Ausführungsform der Torantriebsdrehmomentübertragungsvorrichtung 50 ist von der Funktion und dem wesentlichen Aufbau mit der ersten Ausführungsform 20 vergleichbar, wobei die beiden Lagerteile zum Lagern des Antriebsgliedes bzw. des Abtriebgliedes jedoch nicht durch Einzelteile 5 und 6 eines Kettenknochens 4, sondern als Einzelteile eines als Lagereinrichtung und gleichzeitig zum Schutz des Kettengetriebes wirkenden Übertragungsgehäuses 51 gebildet sind. Demgemäß ist das Übertragungsgehäuse 51 durch zwei getrennt voneinander ausgeführte, entkoppelte und nur elastisch miteinander verbundene Lagerteile, ein Antriebsgliedlagerteil 52 und ein Abtriebsgliedlagerteil 53 gebildet. Beide Lagerteile 52, 53 sind jeweils durch zwei im wesentlichen identisch aufgebaute, spiegelbildlich miteinander verbundene Gehäuseschalen 54a und 54b bzw. 55a und 55b, die jeweils eines der Kettenräder 1 und 3 zwischen sich lagernd aufnehmen gebildet.

Das Antriebsgliedlagerteil 52 ist mit Bohrungen 12a, 12b, 12c zur Verbindung mit dem Antriebsgehäuse 37 des in Fig. 3 dargestellten Getriebemotors 36 versehen. Die beiden Lagerteile 52, 53 sind über die beiden elastischen Verbindungsstellen 7 und 8 eine elastische Verschwenkbewegung und translatorische Schiebebewegung insbesondere parallel zur Kettenebene oder senkrecht zu den Drehachsen der Kettenräder 1 und 3 zulassend verbunden.The third embodiment of the door drive torque transmission device 50 is comparable in function and essential structure to first embodiment 20, wherein the two bearing parts for storing the drive member and the driven member however not by individual parts 5 and 6 of a chain bone 4, but as individual parts one acting as a storage device and at the same time protecting the chain transmission Transmission housing 51 are formed. Accordingly, the transmission case 51 by two separately executed, decoupled and only elastic to each other connected bearing parts, a drive link bearing part 52 and an output link bearing part 53 formed. Both bearing parts 52, 53 are essentially identical by two constructed, mirror-image interconnected housing shells 54a and 54b or 55a and 55b, each of which holds one of the sprockets 1 and 3 between them educated. Like the profiles 5 and 6 of the chain bone 4, the bearing parts 52 and 53 engage with a few millimeters of play between them telescopically. The drive link bearing part 52 is provided with bores 12a, 12b, 12c for connection to the drive housing 37 of the 3 shown in Fig. Geared motor.

Die Kette 2 ist innerhalb der Lagerteile 52, 53 und außerhalb der Verbindungsstellen 7 und 8 geführt. Eine Spanneinrichtung 56 spannt die beiden Trume der Kette 2 durch elastisches Zueinanderziehen. Die beiden Verbindungsstellen 7 und 8 sind durch die hier einstückig mit den Gehäuseschalen 55a und 55b des Abtriebsgliedlagerteils 53 ausgeführten Röhrchen 9', die mit den Gehäuseschalen 54a und 54b des Antriebsgliedlagerteils 52 verbindbaren Bolzen 10 und die zwischen den Röhrchen 9' und den Bolzen 10 angeordneten Gummibuchsen 11 gebildet. Für die beiden Kettenräder 1 und 3 ist eine übliche, als Massenware erhältliche Form gewählt, wobei die Abtriebswelle des Getriebemotors 36 und die Torsionsfederwelle zum Erfassen des jeweiligen Kettenrades 1 bzw. 3 in dieser Form angepasst ausgebildet ist.In Fig. 5, the door drive torque transmission device 50 is removed halved housing shells 54b and 55b shown. The chain 2 is within the bearing parts 52, 53 and outside the connection points 7 and 8. A tensioning device 56 tensions the two strands of chain 2 by elastic contraction. The two Junctions 7 and 8 are integral with the housing shells 55a and 55b of the output member bearing part 53 executed tubes 9 'with the housing shells 54a and 54b of the drive member bearing part 52 connectable bolts 10 and between the tubes 9 'and the bolts 10 arranged rubber bushings 11 are formed. For the two sprockets 1 and 3 is a common, mass-produced shape, the output shaft of the geared motor 36 and the torsion spring shaft for detection of the respective sprocket 1 or 3 is adapted in this form.

Im Betrieb mit entsprechend wie die Torantriebsdrehmomentübertragungsvorrichtung 40 in Fig. 3 zwischen eine Torwelle 33 und ein Torantriebsmotoraggregat 36 geschalteter Torantriebsdrehmomentübertragungsvorrichtung 50 werden Torsionsschwingungen und Stöße sowie ein unrunder Lauf der Torwelle durch über die elastischen Verbindungsstellen 7 und 8 gedämpfte Relativbewegung und insbesondere Relativverschwenkung zwischen den Einzelteilen 52, 53 des Übertragungsgehäuses abgefedert. Dies schont das Tor und das Torantriebsmotoraggregat 36 und auch die Torantriebsdrehmomentübertragungsvorrichtung 50 selbst.Operating with the same as the gate drive torque transmission device 40 in Fig. 3 between a door shaft 33 and a door drive motor assembly 36 connected Gate drive torque transmission device 50 become torsional vibrations and Impacts as well as a non-circular running of the door shaft due to the elastic connection points 7 and 8 damped relative movement and in particular relative pivoting between cushioned the individual parts 52, 53 of the transmission housing.
