Abstract

A rotating drive mechanism for operating the wing of a swinging door, especially of a vehicle. The wing is articulated by pivoting arms to a rotating post, which it rotates along with. When the door is closed, the wing can be raised by axial displacement of the post into a locked position, where locking components on the stationary door frame and on the wing of the door engage each other. The post is driven by a strictly linear mechanism that is controlled by pressure medium and its linear motion is converted into a rotation by a helical transmission. Certain drawbacks are elminated by the improvement wherein the rotating post is coupled to the helical transmission in such a way that, at least while the wing of the door is closing, the post cannot rotate in relation to it but can move axially and, once the post has attained a specified limit of rotation while the wing of the door is closing, the linear drive mechanism will be additionally directly coupled axially to the rotating post in such a way as to lift it.

Description

Die Erfindung betrifft einen Drehantrieb zum Bewegen eines Schwenktürflügels, insbesondere an Fahrzeugen, der mit Schwenkarmen an einer Drehsäule angelenkt und mit dieser schwenkbar und durch axiale Verschiebung der Drehsäule in der Schließstellung in eine Verriegelungsstellung anhebbar ist, in welcher Verriegelungsmittel am feststehenden Türrahmen und am Türflügel miteinander in Eingriff kommen, wobei der Antrieb der Drehsäule durch nur einen druckmittelbetriebenen Linearantrieb erfolgt, dessen Linearbewegung über ein Schraubgetriebe in eine Drehbewegung umgewandelt wird.The invention relates to a rotary drive for moving a swing door leaf, in particular on vehicles, which is articulated with swivel arms on a rotating column and can be pivoted with it and by axial displacement of the rotating column in the closed position into a locking position, in which locking means on the fixed door frame and on the door leaf are interconnected come into engagement, the drive of the rotary column being carried out by only one pressure medium-operated linear drive, the linear movement of which is converted into a rotary movement by means of a screw gear.

Ein derartiger Drehantrieb ist bekannt und beispielsweise in der DE-PS 2 062 135 beschrieben.Such a rotary drive is known and described for example in DE-PS 2 062 135.

Der bekannte Drehantrieb hat die Eigenschaft, daß der Schwenktürflügel nach Abschluß der Schließbewegung in eine Verriegelungsstellung angehoben wird, in der er nicht mit Gewalt geöffnet werden kann und in der auch keine Flatterbewegungen des geschlossenen Türflügels beim Fahren auftreten können.The known rotary drive has the property that the swing door leaf is raised after completion of the closing movement into a locking position in which it cannot be opened by force and in which no fluttering movements of the closed door leaf can occur when driving.

Dabei wird bei einer Ausführungsform des bekannten Drehantriebs die Drehbewegung und die axiale Verschiebung der Drehsäule in die Verriegelungsstellung des Schwenktürflügels durch das zwischen den Linearantrieb und die Drehsäule eingeschaltete Schraubgetriebe bewirkt, wobei von der Tatsache Gebrauch gemacht wird, daß, wenn der Türflügel in die Türöffnung eingefahren ist, eine weitere Drehung der Drehsäule nicht möglich ist, was zur Folge hat, daß die in axialer Richtung auf das Schraubgetriebe wirkende Kraft zu einem Anheben der Drehsäule führt.In one embodiment of the known rotary drive, the rotary movement and the axial displacement of the rotary column into the locking position of the pivoting door leaf is brought about by the screw gear switched on between the linear drive and the rotary column, use being made of the fact that when the door leaf is moved into the door opening is, a further rotation of the rotating column is not possible, with the result that the force acting on the screw mechanism in the axial direction leads to a lifting of the rotating column.

Dabei wird die Drehsäule gegen die Kraft einer Feder angehoben.The rotating column is raised against the force of a spring.

Der bekannte Drehantrieb hat den Nachteil, daß das Reaktionsdrehmoment, welches zum Anheben der Tür und zum Spannen der Feder aufgebracht werden muß, erheblich ist und über die Türdichtung aufgebracht wird. Die dabei auftretenden Reibungskräfte mindern die Hubkraft des Antriebes und erhöhen den Verschleiß der Türdichtungen.The known rotary drive has the disadvantage that the reaction torque which has to be applied for lifting the door and for tensioning the spring is considerable and is applied via the door seal. The friction forces that occur reduce the lifting force of the drive and increase the wear on the door seals.

Wenn der bekannte Drehantrieb nicht mit einer aus der Hubbewegung des Türflügels abgeleiteten Reversiereinrichtung ausgerüstet ist, führt eine beispielsweise von Fahrgästen aufgebrachte Kraft gegen die Schließbewegung des Türflügels zum Anheben der Tür bevor die Schließbewegung beendet ist. In der angehobenen Lage kann aber der Türflügel nicht in die Verriegelungselemente einfahren. Die Tür wird dann nicht vollständig geschlossen.If the known rotary drive is not equipped with a reversing device derived from the lifting movement of the door leaf, a force exerted, for example, by passengers against the closing movement of the door leaf leads to the door being lifted before the closing movement has ended. In the raised position, however, the door leaf cannot move into the locking elements. The door will not be closed completely.

Es ist zwar möglich (DE-PS 2 062 135), die obengenannten Nachteile dadurch zu vermeiden, daß für die Schwenkbewegung und die Hubbewegung des Türflügels getrennte Antriebsaggregate verwendet werden, diese Lösung ist aber wesentlich aufwendiger und beansprucht vor allem mehr Raum, der insbesondere in Fahrzeugen nicht immer zur Verfügung steht.Although it is possible (DE-PS 2 062 135) to avoid the above disadvantages by using separate drive units for the pivoting movement and the lifting movement of the door leaf, this solution is considerably more complex and, above all, takes up more space, particularly in Vehicles are not always available.

Die der Erfindung zugrunde liegende Aufgabe bestand darin, einen Drehantrieb, der im Oberbegriff des Patentanspruchs 1 beschriebenen Bauart so auszubilden, daß bei Beibehaltung einer gemeinsamen Antriebsvorrichtung sowohl für die Schwenkbewegung als auch für die Hubbewegung des Türflügels die geschilderten Nachteile vermieden werden, daß also Schwenkbewegung und Hubbewegung nacheinander eingeleitet werden und dadurch auch ein Anheben des Türblattes vor Beendigung der Schließbewegung nicht möglich ist.The object of the invention was to provide a rotary drive which is of the type described in the preamble of claim 1 in such a way that, while maintaining a common drive device for both the pivoting movement and the lifting movement of the door leaf, the disadvantages described are avoided, that is to say pivoting movement and Lifting movement are initiated one after the other and thus a lifting of the door leaf before the closing movement is not possible.

Die Lösung dieser Aufgabe geschieht erfindungsgemäß dadurch, daß die Drehsäule mindestens in Schließrichtung des Türflügels mit dem Schraubgetriebe drehfest, aber in axialer Richtung verschiebbar gekoppelt ist und beim Erreichen einer vorgegebenen Endposition der Drehbewegung der Drehsäule in Schließrichtung des Türflügels eine zusätzliche direkte Kopplung zwischen dem Linearantrieb und der Drehsäule in axialer Richtung im Sinne einer Hubbewegung der Drehsäule einsetzt.This object is achieved according to the invention in that the rotary column is coupled in a rotationally fixed manner, but displaceably in the axial direction, at least in the closing direction of the door leaf and, when a predetermined end position of the rotary movement of the rotary column in the closing direction of the door leaf, is achieved by an additional direct coupling between the linear drive and the rotating column in the axial direction in the sense of a lifting movement of the rotating column.

Vorteilhafte Ausführungsformen des erfindungsgemäßen Drehantriebs sind weiter unten anhand von Ausführungsbeispielen sowie in den Unteransprüchen beschrieben.Advantageous embodiments of the rotary drive according to the invention are described below on the basis of exemplary embodiments and in the subclaims.

Der Grundgedanke der Erfindung besteht darin, am Ende der Drehbewegung der Drehsäule, die zum Schließen des Türflügels führt, die in axialer Richtung verschiebbare Drehsäule direkt mit dem Linearantrieb zu koppeln und dadurch die Hubbewegung einzuleiten. Dabei kann durch entsprechende Ausgestaltung des Schraubengetriebes dafür gesorgt werden, daß die Drehbewegung des Türflügels vor dem Auslösen der Hubbewegung beendet ist, so daß die beiden Bewegungen voneinander vollständig getrennt nacheinander ablaufen, ohne daß hierzu zwei selbständige Antriebsvorrichtungen notwendig wären.The basic idea of the invention is, at the end of the rotary movement of the rotary column, which leads to the closing of the door leaf, to couple the rotary column, which is displaceable in the axial direction, directly to the linear drive and thereby to initiate the lifting movement. It can be ensured by appropriate design of the screw mechanism that the rotary movement of the door leaf is terminated before the lifting movement is triggered, so that the two movements run completely separately from one another without the need for two independent drive devices.

Die Kolbenstange 4.4 ist zwischen dem Zylinderdeckel 1.2 und dem inneren Zylindermantel 4.2 aus dem Antriebszylinder 4 dichtend herausgeführt und mit einem Koppelglied 3 verbunden, das bei diesem Ausführungsbeispiel als lange, sich nach unten in das Innere des inneren Zylindermantels 4.2 hinein erstreckende Schraubenmutter ausgebildet ist, die eine den Rotor eines Schraubgetriebes bildende Schraubenspindel 2 umfaßt, die einstückig mit einem nach außen geführten Abtriebswellenstummel 2.1 verbunden ist.The rotary drive housing, which is also denoted overall by 1 in FIG. 2, is cylindrical and has two end covers 1.1 and 1.3 and an annular intermediate flange 1.2 and a cylindrical jacket with grooves 5.2 forming the stator and a cover sleeve 1.4. The outer wall 4.1 in the lower part of the housing is at the same time the outer cylinder jacket of a drive cylinder 4. The drive cylinder 4 consists of two cylinder jackets 4.1 and 4.2 arranged coaxially one inside the other, the cylinder base 1.1 and the cylinder cover 1.2. The piston 4.3 of the cylinder is an annular piston which is guided in a sliding and sealing manner in the space between the outer cylinder jacket 4.1 and the inner cylinder jacket 4.2 and which is connected to a tubular piston rod 4.4 which is guided axially directly along the inner cylinder jacket 4.2. The piston rod 4.4 is sealingly led out of the drive cylinder 4 between the cylinder cover 1.2 and the inner cylinder jacket 4.2 and connected to a coupling member 3, which in this embodiment is designed as a long screw nut which extends downward into the interior of the inner cylinder jacket 4.2 comprises a screw spindle 2 forming the rotor of a screw transmission, which is connected in one piece to an outward output shaft stub 2.1.

Weiterhin ist das Koppelglied 3 mit einer Führungsvorrichtung 5 drehfest verbunden, die die Verdrehung des. Koppelgliedes bei einer Bewegung des Kolbens 4.3 während des ersten Teils der Schließbewegung in axialer Richtung bestimmt. Die Führungsvorrichtung 5 weist drehbar gelagerte Rollen 5.1 auf, die in den mit dem Drehantriebsgehäuse 1 fest verbundenen Nuten 5.2 laufen. Die Führungsvorrichtung 5 ist jeweils an mindestens zwei Seiten des Koppelgliedes 3 angeordnet.Furthermore, the coupling member 3 is rotatably connected to a guide device 5 which determines the rotation of the coupling member when the piston 4.3 moves during the first part of the closing movement in the axial direction. The guide device 5 has rotatably mounted rollers 5.1 which run in the grooves 5.2 fixedly connected to the rotary drive housing 1. The guide device 5 is arranged on at least two sides of the coupling member 3.

Die Nuten 5.2 besitzen im unteren Teil schraubenförmige Abschnitte 5.21 und 5.22, an die sich am oberen Ende jeweils ein achsparalleler Abschnitt 5.23 anschließt. Die Schraubenspindel 2 ist in der Nähe ihres oberen Endes starr mit einer Bundbüchse 12 verbunden, die in der unteren Endlage der prinzipiell axial verschiebbaren Schraubenspindel 2 auf ainem Axialnadellager 14 aufliegt, das im oberen Stimdeckel 1.3 des Gehäuses angeordnet ist. Am unteren Ende der Bundbüchse 12 ist eine Schraubkappe 13 angeordnet, deren Unterfläche eine Anschlagfläche für die obere Endfläche 3.1 des Koppelgliedes 3 bildet. Der Abtriebswellenstummel 2.1 ist über ein Verbindungsstück 15 drehfest und hubfest mit der Drehsäule 25 verbunden.The grooves 5.2 have helical sections 5.21 and 5.22 in the lower part, to each of which an axially parallel section 5.23 is connected at the upper end. The screw spindle 2 is rigidly connected in the vicinity of its upper end to a collar sleeve 12 which, in the lower end position of the screw spindle 2, which is in principle axially displaceable, rests on an axial needle bearing 14 which is arranged in the upper end cap 1.3 of the housing. At the lower end of the collar sleeve 12, a screw cap 13 is arranged, the lower surface of which forms a stop surface for the upper end surface 3.1 of the coupling member 3. The output shaft stub 2.1 is connected in a rotationally fixed and stroke-fixed manner to the rotating column 25 via a connecting piece 15.

Wie aus den Fig. 2a und 2b ersichtlich, besitzt die Bundbüchse 12 an ihren oberen Rand 12.1 eine axiale Nut 12.2 und im Stirndeckel 1.3 ist einseitig eine Stützplatte 16 angeordnet, an der die Oberseite des Randes 12.1 anliegt. Nur in einer bestimmten Winkelstellung der Bundbüchse 12 kann diese bei einem Hochfahren des Koppelgliedes 3 axial nach oben verschoben werden, nämlich wenn die Stützplatte 16 durch die Nut 12.2 hindurchtreten kann. In Fig. 2b ist die Bundbüchse 12 gegenüber ihrer Position in Fig. 2a um einen Winkel von ca. 150° verdreht dargestellt, so daß die Nut 12.2 über der Stützplatte 16 liegt.As can be seen from FIGS. 2a and 2b, the collar sleeve 12 has an axial groove 12.2 on its upper edge 12.1 and a support plate 16 is arranged on one side in the end cover 1.3, against which the upper side of the edge 12.1 bears. Only in a certain angular position of the collar sleeve 12 can this be moved axially upward when the coupling member 3 is raised, namely when the support plate 16 can pass through the groove 12.2. In Fig. 2b, the collar sleeve 12 is shown rotated by an angle of approximately 150 ° relative to its position in Fig. 2a, so that the groove 12.2 lies above the support plate 16.

Die Funktionsweise des in den Fig. 2, 2a, 2b und 2c dargestellten Drehantriebs ist folgende:

  • In Fig. 2 ist im unteren Teil das Schraubgetriebe in der Drehanfangslage dargestellt. In der linken Hälfte A ist die Lage der Führungsvorrichtung 5 in der Drehendlage, aber vor Einsetzen des Hubes strichpunktiert angedeutet. In der rechten Hälfte B ist die Lage der Führungsvorrichtung 5 in der Hubendlage angedeutet und die Lage der Schraubenspindel 2 und der mit ihr verbundenen Teile in der Hubendlage dargestellt.
The mode of operation of the rotary drive shown in FIGS. 2, 2a, 2b and 2c is as follows:
  • In Fig. 2, the helical gear is shown in the lower part in the starting position. In the left half A, the position of the guide device 5 in the rotational end position is indicated by dash-dotted lines before the stroke is inserted. In the right half B, the position of the guide device 5 is indicated in the stroke end position and the position of the screw spindle 2 and the parts connected to it in the stroke end position.

Wird der Antriebszylinder 4 über die Einlaßöffnung 4.5 mit Druckmittel beaufschlagt, so bewegt sich der Kolben 4.1 in axialer Richtung und führt über die Kolbenstange 4.4 das Koppelglied 3 in axialer Richtung mit. Da dieses in die Schraubenspindel 2 eingreift und durch die Führungsvorrichtungen 5 geführt ist, hat dies zur Folge, daß die Schraubenspindel 2 und damit der Abtriebswellenstummel 2.1 in Drehung versetzt werden. Ein Anheben der Schraubenspindel 2 und damit der Drehsäule 25 wird bei dieser Bewegung durch das Gewicht des Türflügels und gegebenenfalls eine Gegenfeder und darüber hinaus dadurch verhindert, daß der obere Rand 12.1 der Bundbüchse 12 an der Stützplatte 16 anliegt. Bei dieser Drehbewegung liegt die Bundbüchse 12 auf dem Axialnadellager 14 auf. Wenn die Rollen 5.1 der Führungsvorrichtung 5 in die oberen Nutenenden 5.23 gelangen, ist die weitere Verdrehung des Koppelgliedes 3 blockiert. Gleichzeitig fährt die obere Endfläche 3.1 des Koppelgliedes 3 an die Unterfläche der Schraubkappe 13 der Bundbüchse 12 an und hebt diese und damit auch die Drehsäule 25 an. In dieser Phase befindet sich die Bundbüchse 12 in einer Winkelposition, in der die Stützplatte 16 durch die Nut 12.2 hindurchtritt, so daß die Drehsäule 25 insgesamt um den Betrag a angehoben werden kann. Die obere Endlage der Schraubenspindel 2 wird durch die Verriegelungsmittel und zur Sicherheit zusätzlich durch einen Hubendanschlag 1.21 im Antriebszylinder 4 bestimmt.If the drive cylinder 4 is pressurized via the inlet opening 4.5, then the piston 4.1 moves in the axial direction and carries the coupling member 3 in the axial direction via the piston rod 4.4. Since this engages in the screw spindle 2 and is guided by the guide devices 5, this has the consequence that the screw spindle 2 and thus the output shaft stub 2.1 are rotated. A lifting of the screw spindle 2 and thus the rotating column 25 is prevented during this movement by the weight of the door leaf and possibly a counter spring and moreover by the fact that the upper edge 12.1 of the collar sleeve 12 rests on the support plate 16. During this rotary movement, the collar sleeve 12 rests on the axial needle bearing 14. When the rollers 5.1 of the guide device 5 reach the upper groove ends 5.23, the further rotation of the coupling member 3 is blocked. At the same time, the upper end surface 3.1 of the coupling member 3 approaches the lower surface of the screw cap 13 of the collar sleeve 12 and lifts it and thus also the rotating column 25. In this phase, the collar sleeve 12 is in an angular position in which the support plate 16 passes through the groove 12.2, so that the rotary column 25 can be raised by a total of a. The upper end position of the screw spindle 2 is determined by the locking means and for safety also by a stroke end stop 1.21 in the drive cylinder 4.

Bei der Gegenbewegung wird dem Antriebszylinder 4 über den Einlaß 4.6 Druckmittel zugeführt und es erfolgt erst eine Absenkbewegung der Schraubenspindel 2, wobei die untere Endlage der Schraubenspindel wiederum durch das Aufliegen der Bundbüchse 12 auf dem Axialnadellager 14 bestimmt ist. Es schließt sich dann die Drehbewegung zum Öffnen des Schwenktürflügels an.During the counter-movement, pressure medium is supplied to the drive cylinder 4 via the inlet 4.6 and there is only a lowering movement of the screw spindle 2, the lower end position of the Screw spindle is in turn determined by the resting of the collar sleeve 12 on the axial needle bearing 14. This is followed by the rotary movement to open the swing door leaf.

Um beim Ausfallen der Luftversorgung des Antriebszylinders 4 ein Herunterfallen des Schwenktürflügels aus der Verriegelungsstellung zu verhindem, kann an der Drehsäule eine Verriegelungsvorrichtung vorgesehen sein, die weiter unten anhand eines anderen Ausführungsbeispiels näher erläutert wird.In order to prevent the pivoting door leaf from falling out of the locking position when the air supply to the drive cylinder 4 fails, a locking device can be provided on the rotating column, which is explained in more detail below using another exemplary embodiment.

In den Fig. 3 bis 3c ist eine etwas andere Ausführungsform eines Drehantriebs dargestellt. Dabei zeigt Fig. 3 den Drehantrieb bei geöffnetem Türflügel, Rg. 3a den Drehantrieb bei geschlossenem Türflügel vor dem Anheben in die Verriegelungsstellung und Fig. 3b den Drehantrieb in der Hubendlage des Türflügels.3 to 3c, a somewhat different embodiment of a rotary drive is shown. 3 shows the rotary drive when the door leaf is open, FIG. 3a shows the rotary drive when the door leaf is closed before lifting it into the locking position, and FIG. 3b shows the rotary drive in the stroke end position of the door leaf.

Das insgesamt mit 6 bezeichnete Drehantriebsgehäuse besitzt an den beiden Stirnseiten zwei Stimdeckel 6.1 und 6.3 und in der Mitte einen ringförmigen Zwischenflansch 6.2 sowie einen zylindrischen Mantel mit Nuten 8.4 den Stator bildend, der mit dem Zwischenflansch 6.2 abschließt. Der Mantel ist mit einer Hülse 6.4 abgedeckt. Der untere Teil zwischen dem Stirndeckel 6.1 und dem Zwischenflansch 6.2 bildet einen Hohlzylinder 9.1, der zu dem weiter unten beschriebenen Antriebszylinder 9' gehört. Der Antriebszylinder 9 besteht aus dem äußeren Zylindermantel 9.1 und einem inneren Zylindermantel 9.2, dem Zylinderboden 6.1 und dem Zylinderdeckel 6.6. Im Raum zwischen den beiden Zylindermänteln 9.1 und 9.2 ist ein Ringkolben 9.3 dichtend geführt, dessen rohrförmige Kolbenstange 9.4 den inneren Zylindermantel 9.2 umfaßt und aus dem Antriebszylinder 9 am Zylinderdeckel 6.6 dichtend herausgeführt ist. An dem herausgeführten Ende der Kolbenstange 9.4 ist ein Koppelglied 8 befestigt, das an zwei gegenüberliegenden Seiten jeweils ein Rollenpaar 8.1-8.2 trägt. Die koaxial zueinander angeordneten Rollen 8.1 und 8.2 laufen jeweils in Nutenführungen 8.3 und 8.4. Die Nutenführung 8.3 befindet sich in einem Rotor 7.4, der drehfest mit einer Welle 7.3 verbunden ist, welche koaxial durch das Drehantriebsgehäuse 6 und durch den Innenraum des inneren Zylindermantels 9.2 geführt ist. Die Welle 7.3 ist an beiden Seiten aus dem Antriebsgehäuse 6 herausgeführt. Das in der Zeichnung obere Ende der Welle 7.3 ist einstückig mit einem aus dem Gehäuse herausgeführten Abtriebswellenstummel 7.2 verbunden, der seinerseits fest mit der Drehsäule 25' verbunden ist, an der der obere Schwenkarm 26' angeordnet ist. Die Rolle 8.2 des Koppelgliedes 8 ist in einer zweiten Nutenführung 8.4 des Stators geführt, die fest mit dem SUmdeckel 6.3 und damit dem Drehantriebsgehäuse 6 verbunden ist. Die Nutenführungen 8.3 und 8.4 sind schraubenförmig mit entgegengesetztem Steigungswinkel ausgebildet.The rotary actuator housing, designated overall by 6, has two end covers 6.1 and 6.3 on the two end faces and in the middle an annular intermediate flange 6.2 and a cylindrical jacket with grooves 8.4 forming the stator, which ends with the intermediate flange 6.2. The jacket is covered with a sleeve 6.4. The lower part between the end cover 6.1 and the intermediate flange 6.2 forms a hollow cylinder 9.1, which belongs to the drive cylinder 9 'described below. The drive cylinder 9 consists of the outer cylinder jacket 9.1 and an inner cylinder jacket 9.2, the cylinder base 6.1 and the cylinder cover 6.6. In the space between the two cylinder jackets 9.1 and 9.2, an annular piston 9.3 is sealingly guided, the tubular piston rod 9.4 of which encompasses the inner cylinder jacket 9.2 and is sealingly guided out of the drive cylinder 9 on the cylinder cover 6.6. A coupling member 8 is attached to the end of the piston rod 9.4 that carries a pair of rollers 8.1-8.2 on two opposite sides. The coaxially arranged rollers 8.1 and 8.2 each run in groove guides 8.3 and 8.4. The groove guide 8.3 is located in a rotor 7.4, which is connected in a rotationally fixed manner to a shaft 7.3, which is guided coaxially through the rotary drive housing 6 and through the interior of the inner cylinder jacket 9.2. The shaft 7.3 is led out of the drive housing 6 on both sides. The upper end of the shaft 7.3 in the drawing is connected in one piece to an output shaft stub 7.2 led out of the housing, which in turn is firmly connected to the rotating column 25 'on which the upper swivel arm 26' is arranged. The roller 8.2 of the coupling member 8 is guided in a second slot guide 8.4 of the stator, which is firmly connected to the SU cover 6.3 and thus to the rotary drive housing 6. The slot guides 8.3 and 8.4 are helical with an opposite pitch angle.

Das in der Zeichnung untere Ende der Welle 7.3 ist einstückig mit einem Abtriebswellenstummel 7.1 verbunden, an dem der untere Schwenkarm 28' für den Türflügel befestigt ist. Die Anordnung des Drehantriebs ist also geringfügig anders als in Fig. 1 dargestellt.The lower end of the shaft 7.3 in the drawing is connected in one piece to an output shaft stub 7.1 to which the lower swivel arm 28 'for the door leaf is fastened. The arrangement of the rotary drive is therefore slightly different from that shown in FIG. 1.

Der Rotor 7.4 ist über ein Kugellager 7.5 am Zwischenflansch 6.2 drehbar gelagert. Die Ausgestaltung der Nutenführungen ist in Fig. 4 näher dargestellt. Die Nutenführung 8.4 weist einen ersten Abschnitt 8.41 auf und einen zweiten Abschnitt 8.42 mit geringfügig veränderter Steigung, die zu einer Änderung des Übersetzungsverhältnisses führt. In einem jeweils letzten Abschnitt 8.43 bzw. 8.33 verlaufen die Nutenführungen achsparallel.The rotor 7.4 is rotatably mounted on the intermediate flange 6.2 via a ball bearing 7.5. The design of the groove guides is shown in more detail in FIG. 4. The groove guide 8.4 has a first section 8.41 and a second section 8.42 with a slightly changed slope, which leads to a change in the transmission ratio. In a last section 8.43 or 8.33 respectively, the groove guides run axially parallel.

Die Welle 7.3 ist über die starr mit ihr verbundene Nabe 7.31 und ein die axiale Verschiebung der Welle 7.3 gestattendes Vielkeilprofil 7.41 längsverschieblich, aber drehfest mit dem Rotor 7.4 gekoppelt. Die untere Endlage der Welle 7.3 gegenüber dem Rotor 7.4 wird durch Aufliegen einer Mutter 7.32, die mit der Nabe 7.31 verbunden ist, auf der oberen Fläche 7.42 des Rotors 7.4 bestimmt. Die obere Endlange der Welle 7.3 wird durch einen Hubendanschlag 9.7 im Antriebszylinder 9 bestimmt.The shaft 7.3 is longitudinally displaceable but non-rotatably coupled to the rotor 7.4 via the hub 7.31 rigidly connected to it and a multi-spline profile 7.41 permitting the axial displacement of the shaft 7.3. The lower end position of the shaft 7.3 relative to the rotor 7.4 is determined by resting a nut 7.32, which is connected to the hub 7.31, on the upper surface 7.42 of the rotor 7.4. The upper end length of the shaft 7.3 is determined by a stroke end stop 9.7 in the drive cylinder 9.

Bei einer Zuführung von Druckmittel über den Einlaß 9.5 zum Antriebszylinder 9 bewegt sich der Kolben 9.3 im Raum zwischen den beiden Zylindermänteln 9.1 und 9.2 aufwärts, wodurch über das Koppelglied 8 die beiden Rollen 8.1 und 8.2 in axialer Richtung mitgeführt werden. Die Bewegung der Rollen 8.1 und 8.2 in den Nutenführungen 8.3 und 8.4 ergibt infolge der gegensinnigen Steigung dieser Nuten eine Verdrehung des Rotors 7.4 gegenüber dem Stator bzw. dem Drehantriebsgehäuse 6. Die Welle 7.3 und mit ihm die Abtriebswellenstummel 7.2 und 7.1 werden dadurch verdreht.When pressure medium is supplied via the inlet 9.5 to the drive cylinder 9, the piston 9.3 moves upward in the space between the two cylinder jackets 9.1 and 9.2, as a result of which the two rollers 8.1 and 8.2 are carried along in the axial direction via the coupling member 8. The movement of the rollers 8.1 and 8.2 in the groove guides 8.3 and 8.4 results in a rotation of the rotor 7.4 with respect to the stator or the rotary drive housing 6 due to the opposite slope of these grooves. The shaft 7.3 and with it the output shaft stubs 7.2 and 7.1 are thereby rotated.

Wenn bei der Aufwärtsbewegung des Koppelgliedes 8 die Rollen 8.1 und 8.2 in die letzten achsparallelen Abschnitte der Nutenführungen 8.3 und 8.4 einlaufen, ist die weitere Verdrehung der Welle 7.3 blockiert.If, during the upward movement of the coupling member 8, the rollers 8.1 and 8.2 enter the last axially parallel sections of the groove guides 8.3 and 8.4, the further rotation of the shaft 7.3 is blocked.

In dieser in Fig. 3a dargestellten Stellung legt sich eine mit der Kolbenstange 9.4 verbundene Hülse 10 an die Unterseite der Nabe 7.31 an und bei der weiteren Bewegung des Kolbens 9.3 wird die Welle 7.3 und damit die Drehsäule 25' in die Hubendlage, wie sie in Fig. 3b dargestellt ist, angehoben und damit der Türflügel verriegelt.In this position shown in Fig. 3a, a sleeve 10 connected to the piston rod 9.4 bears against the underside of the hub 7.31 and with the further movement of the piston 9.3, the shaft 7.3 and thus the rotary column 25 'into the stroke end position, as shown in FIG Fig. 3b is shown, raised and thus the door leaf locked.

Das Anheben der Welle 7.3 erfolgt dabei ohne Belastung der Rollen 8.1 und 8.2.The shaft 7.3 is lifted without loading the rollers 8.1 and 8.2.

Eine Umkehrung der Bewegungsrichtung, also das Absenken der Welle 7.3 und Wiederöffnen des Schwenktürflügels durch Verdrehung der Welle 7.3, wird durch Zuführung von Druckmittel zum Einlaß 9.6 des Antriebszylinders 9 erreicht.A reversal of the direction of movement, that is, the lowering of the shaft 7.3 and reopening of the swing door leaf by turning the shaft 7.3, is achieved by supplying pressure medium to the inlet 9.6 of the drive cylinder 9.

Damit beim Ausfall der Luftversorgung für den Antriebszylinder 9 in Schließrichtung der Türflügel nicht absinken kann und sich damit selbst entriegelt, ist eine Verriegelungsvorrichtung vorgesehen, deren Aufbau Fig. 3c zu entnehmen ist. Diese Verriegelungsvorrichtung weist einen Schwenkhebel 20 auf, der sich unter Wirkung einer Druckfeder 18 bei angehobener Welle 7.3 unter die Mutter 7.32 schiebt und damit die Welle 7.3 in der Endlage verriegelt. Die Druckfeder 18 ist innerhalb eines Entriegelungszylinders17 angeordnet, dessen Kolben über eine Kolbenstange 17.1 mit dem Schwenkhebel 20 derart verbunden ist, daß beim Beaufschlagen des Entriegelungszylinders mit Druckmittel eine pneumatische Entriegelung stattfindet. Über einen an der Drehachse des Hebels 20 angeordneten Vierkant 19 ist auch eine Entriegelung von Hand möglich.A locking device is provided so that the air supply for the drive cylinder 9 cannot drop in the closing direction and thus unlock itself, the structure of which can be seen in FIG. 3c. This locking device has a pivoting lever 20 which, under the action of a compression spring 18, pushes under the nut 7.32 when the shaft 7.3 is raised and thus locks the shaft 7.3 in the end position. The compression spring 18 is arranged within an unlocking cylinder 17, the piston of which is connected via a piston rod 17.1 to the pivoting lever 20 in such a way that when pressure is applied to the unlocking cylinder pneumatic unlocking takes place. Unlocking by hand is also possible via a square 19 arranged on the axis of rotation of the lever 20.
