Definitions

  • the invention relates to a door unit, in particular motor vehicle door unit, with a motion transmission member connected to a door with drive shaft, and with a force applied by the drive shaft coupling member variable clamping force.
  • a door unit of the structure described above is described in the embodiment as a motor vehicle door unit for the motorized actuation of a tailgate as a door leaf in DE 198 44 265 A1.
  • the coupling member variable clamping force serves as a safety coupling.
  • a door unit in which the local coupling member acts as a braking device or blocking mechanism.
  • the locking mechanism is used to lock the hinged door to a vehicle body. This happens for the reason that, for example, during the door opening process, an obstacle appears and the door could collide with the obstacle.
  • the blocking device ensures that a collision between the door leaf and the obstacle is prevented.
  • a door unit is described in the prior art according to DE 10 2009 006946 A1, which is equipped with a biased by a spring friction brake device. The friction brake device dampens door movements. Depending on the path completed by the door, the spring builds up a differently designed braking force.
  • a generic door unit in the invention is characterized in that the coupling member is formed as a function of the rotational speed of the drive shaft releasable slip clutch.
  • the invention thus first of all makes use of a coupling element designed as a sliding clutch.
  • the triggering of the slip clutch is predominantly not dependent on the torque, but in the context of the invention as a function of the rotational speed of the drive shaft.
  • the drive shaft of theoptsübertragungs- member ensures that designed as a slip clutch coupling member is triggered or not.
  • the slip clutch is advantageously equipped with at least one friction element completely or partially enclosing the drive shaft.
  • at least one friction element completely or partially enclosing the drive shaft.
  • two friction elements are realized. This can be attributed to the fact that the drive shaft rotates regularly taking into account two different directions of rotation. These two different directions of rotation correspond on the one hand to an opening movement of the door leaf and on the other hand to a closing movement of the door leaf.
  • the release of the friction element in the course of the door opening may with a
  • the operation of the coupling member or the slip clutch and consequently of the friction element is accompanied by the fact that the friction element is designed to be changeable from its wrap cross section. If the Umschlingungsquer Beatles of the friction element is reduced, so the friction element applies to the drive shaft and encloses this wholly or partially. For this purpose, the engaged position of the coupling member and consequently the slip clutch corresponds. If, however, the friction element is widened by its wrap-around cross-section, then the previously held drive shaft is released and can subsequently rotate more or less freely thereafter. Then the disengaged position of the coupling member and thus the slip clutch and thus the friction element is achieved.
  • the friction element is designed for this purpose as variable in diameter spring.
  • the said spring may be a wrap spring.
  • Such a wrap spring is characterized by a helical course of its spring coils similar to a coil spring.
  • a wrap spring may also have a non-round spring cross-section, but rather is equipped with a rectangular spring cross-section.
  • the broad side of the rectangular spring cross section of the enclosed by the wrap spring drive shaft are facing.
  • the highest possible frictional forces between wrap spring and friction element and drive shaft can be transmitted.
  • the friction element is designed changeable from its Umschlingungsquerites ago and adapted otherwise to the drive shaft.
  • the drive shaft is usually designed cylindrical, the friction element has logically an arcuate or circular character, so that the described Umschlingungs cross-sectional change is usually accompanied by a change in diameter of the friction element.
  • an adjusting element is usually provided, which interacts with the friction element.
  • the actuator is connected to the Antnebswelle. Consequently, the drive shaft controls the friction element via the adjusting element. Depending on the rotational speed of the drive shaft, the friction element is acted upon by the adjusting element more or less. D. h., The actuator interacts with the friction element, in accordance with the rotational speed of the drive shaft.
  • a friction element corresponds to a direction of rotation of the drive shaft. Since the friction element is usually designed as a variable in diameter spring, it is usually worked in this case with two friction elements designed as springs. To illustrate the different directions of rotation of the drive shaft and their consideration, the two said springs are usually equipped with opposing turns. In this way, a spring interacts with a direction of rotation of the drive shaft, whereas the other spring interacts with the other direction of rotation of the drive shaft.
  • the actuator carries these two different directions of rotation account for the fact that the actuator connected to the actuator depending on the direction of rotation of the drive shaft acts either one friction element or the other friction element.
  • the interpretation is usually made such that the actuator after exceeding a predetermined rotational speed of the drive shaft releases the friction element of the drive shaft. If the predetermined rotational speed is exceeded, the actuating element applies the friction element to the drive shaft.
  • the actuator is equipped with an eccentric or the like actuator. With the help of this actuator, the Umschlingungsquerites the friction element can be changed.
  • the design is usually made so that the actuator acts in two directions, namely the following direction of rotation of the drive shaft. In this way, one and the same actuator can change both the friction element for the one direction of rotation and the friction element for the other direction of rotation in its Umschlingungsquerexcellent as desired.
  • the actuating element usually engages at one end of the friction element.
  • the other end of the friction element is held in contrast. Since it is advantageous in the friction element is a spring, the actuator engages at one end of the spring, while the other end of the spring undergoes a fixation. If you work with two springs, one spring per direction of rotation of the drive shaft, the interpretation is made such that the respective free ends of the springs are adjacent to each other. In this way, one and the same actuator can be used to act on the two free spring ends.
  • the actuator is usually a rotatable shaft or rod, which is usually equipped with a damping element.
  • the rotatable shaft or rod usually dips into the damping element in question.
  • the damping element is advantageously equipped with a chamber which is filled with a viscous medium.
  • the actuator is connected to the chamber.
  • the actuator may be an eccentric or else
  • the actuator is directly or indirectly driven and acted upon by the drive shaft. As soon as the drive shaft rotates, the actuator also normally undergoes a rotation.
  • the rotational speed of the actuating element or its movements are damped by the damping element. From a certain rotational speed of the control element, the control element enclosing or receiving chamber is deflected with the actuator connected thereto. Then, the predetermined rotational speed of the drive shaft is reached, which corresponds to the fact that the friction element is released from the drive shaft.
  • the deflected actuator in turn ensures that the free end of the spring is acted upon. Since the free end of the opposite end of the spring is fixed, the application of the free end of the spring ensures that the spring undergoes the desired diameter extension. As a result, the previously held drive shaft is released and can rotate immediately and almost without resistance. In this way, the slip clutch can be triggered in response to the rotational speed of the drive shaft. Once the said rotational speed is exceeded, the actuator can no longer act on the chamber and with her the connected actuator in the sense of rotation, so that the free end of the spring experiences no deflection. The spring contracts and attaches itself to the drive shaft, which is subsequently blocked.
  • a door unit which is equipped with a special coupling member variable clamping force.
  • the coupling member can be triggered in dependence on the rotational speed of the drive shaft.
  • the coupling member or realized at this point slip clutch is either engaged or disengaged in accordance with the rotational speed of the drive shaft.
  • the freely rotating drive shaft corresponds to the fact that the hereby interactive door leaf of the door unit can be easily moved back and forth.
  • a certain speed of the pivoting movement of the door leaf is required, which corresponds to the fact that the drive shaft exceeds the predetermined rotational speed.
  • the speed of the drive shaft below the predetermined rotational speed and the door undergoes a blockage. All this can be achieved particularly cost-effectively, simply and without additional electrical or mechanical links of complicated structure.
  • the main benefits are the main benefits.
  • Fig. 3 shows a detail of the Fig. 2 in a modified embodiment
  • Fig. 4 is a schematic cross-section through the article according to Fig. 2 along a line A-A.
  • a door unit is shown, in which it is a motor vehicle door unit in the embodiment.
  • This has a door 1, which is articulated in a pivot point 2 to a motor vehicle body and can be opened and closed about this pivot point 2 in the direction indicated by a double arrow pivoting direction.
  • a pivoting movement s is completed with a certain swinging speed s.
  • coupling member 5 is applied variable clamping force.
  • the coupling member 5 can be substantially engaged and disengaged.
  • the engaged position of the coupling member 5 corresponds to the fact that the coupling member 5, the drive shaft 4 holds.
  • the disengaged position of the coupling member 5 corresponds to the fact that the drive shaft 4 is released from the coupling member 5 and rotates without resistance or almost without resistance.
  • the coupling member 5 is formed as a slip clutch 5. In this case, the coupling member 5 and the slip clutch 5 is triggered in response to the rotational speed of the drive shaft 4.
  • the coupling member 5 If the rotational speed of the drive shaft 4 exceeds a predetermined rotational speed, the coupling member 5 is disengaged and releases the drive shaft 4. When falling below the predetermined rotational speed, the coupling member 5 and the slip clutch 5 is engaged and keeps the drive shaft 4 free.
  • the slip clutch 5 is equipped with at least one drive element 4 completely or partially enclosing friction element 6, 7.
  • two friction elements 6, 7 are provided in the context of the embodiment. This includes a friction element 6 to a rotational direction of the drive shaft 4, in this case, their rotation in a clockwise direction.
  • the other friction element 7 belongs to a counterclockwise rotation of the drive shaft 4.
  • Both friction elements 6, 7 are designed to be changeable from their Umschlingungsquerrough forth.
  • the respective friction element 6, 7 is a variable in diameter diameter spring 6, 7.
  • the wrap spring 6, 7 has a rectangular spring cross-section, wherein the largest width of the rectangular spring cross-section of the drive shaft 4 faces. As a result, maximum friction forces can be transmitted to the drive shaft 4 by the spring 6, 7. It can be seen that the two springs 6, 7 are equipped with opposing turns. Each spring 6, 7 has a respective fixed end 6a, 7a and a free end 6b, 7b.
  • the interpretation can be such that the respective fixed ends 6a, 7a have a maximum distance from each other, whereas the free ends 6b, 7b are arranged in close proximity to each other , In this way it is possible to apply the respective friction element 6, 7 with a single actuator 8.
  • the actuator 8 is connected to the drive shaft 4, in the context of the embodiment with the interposition of a damping element 9.

  • the actuator 11 performs only rotations or pivotal movements in the counterclockwise direction, as a corresponding arrow in Fig. 4 makes clear.
  • an unspecified transfer member is interposed between the adjusting element 8 and the actuator 11, which converts clockwise movements of the adjusting element 8 in such a counterclockwise direction of the actuator 11, so that the actuator 11 performs only the already mentioned rotations counterclockwise.
  • the damping element 9 has a chamber 10 which receives a viscous medium in the interior. Depending on how strongly the drive shaft 4 rotates, the viscous medium located in the interior of the chamber 10 is more or less "entrained” and, at a certain and predetermined rotational speed of the drive shaft 4, ensures that the chamber 10 undergoes a deflection. In the same way, the adjusting element 8 is deflected and undergoes the actuator 11 indirectly connected via the transmission member actuator 11, an application.
  • the actuator 11 is in the context of the embodiment of FIG. 4 to a double cam.
  • the actuator 11 and the double cam 11 operates on plunger 12, each deflecting the free end 6 b of the spring 6 and 7 b on the other hand, the spring 7.
  • a rotation of the actuator or double cam 11 in each direction of rotation of the adjusting element 8 causes the free end 6b of the spring 6 and the free end 7b of the spring 7 are acted upon by the plunger 12 and a diameter increase indicated in FIG the associated spring 6, 7 correspond.
  • This increase in diameter of the spring 6, 7 causes the previously of the spring 6, 7 causes the previously held by the spring 6, 7 is on ebswelle 4 is released.
  • Fig. 3 illustrates a somewhat modified embodiment, in which a spring 6 between the one hand, the drive shaft 4 and on the other hand, a fixed housing 13 is interposed. If the spring 6 is increased in diameter, it settles on the outside against the fixed housing 6 enclosing the spring 6. If this happens over the entire length of the spring 6, as a result of this, the previously held by the spring 6 and enclosed drive shaft 4 is released. If, however, it only partially to an increase in diameter along the length of the
  • the basic mode of operation is as follows. As soon as the door leaf 1 performs a pivoting movement s, the drive shaft 4 is rotated. At first friction forces of the two friction elements or springs 6, 7 must be overcome. The drive shaft 4 also rotates within the chamber 10. However, these rotations do not cause the chamber 10 and also the adjoining the chamber 10 actuator 8 undergo a rotation.

However, if the pivoting speed S of the door leaf 1 or the associated rotational speed of the drive shaft 4 exceeds a predetermined value, the drive shaft 4 with the interposition of the damping element 9 in a position to rotate the chamber 10.
  • the rotating chamber 10 ensures via the actuator 8 and the indirectly connected thereto actuator 11 that even the relevant actuator 11 and the associated double cam 11 undergoes a counterclockwise rotation.
  • This rotation is indicated in Fig. 4 by an arrow and causes the two tappets 2 are acted upon by the two cams.

Description

Türeinheit Beschreibung:  Door unit Description:
Die Erfindung betrifft eine Türeinheit, insbesondere Kraftfahrzeugtüreinheit, mit einem an einen Türflügel angeschlossenen Bewegungsübertragungsglied mit Antriebswelle, und mit einem von der Antriebswelle beaufschlagten Kupplungsglied veränderbarer Schließkraft. The invention relates to a door unit, in particular motor vehicle door unit, with a motion transmission member connected to a door with drive shaft, and with a force applied by the drive shaft coupling member variable clamping force.
Eine Türeinheit des eingangs beschriebenen Aufbaus wird in der Ausgestaltung als Kraftfahrzeug-Türeinheit zur motorischen Betätigung einer Heckklappe als Türflügel in der DE 198 44 265 A1 beschrieben. Hier dient das Kupplungsglied veränderbarer Schließkraft als Sicherheitskupplung. A door unit of the structure described above is described in the embodiment as a motor vehicle door unit for the motorized actuation of a tailgate as a door leaf in DE 198 44 265 A1. Here, the coupling member variable clamping force serves as a safety coupling.
Darüber hinaus kennt man durch die DE 10 2008 053 087 A1 eine derartige Türeinheit, bei welcher das dortige Kupplungsglied als Bremsvorrichtung bzw. Blockiermechanismus fungiert. Der Blockiermechanismus wird dazu eingesetzt, den schwenkbaren Türflügel gegenüber einer Fahrzeugkarosserie festzusetzen. Das geschieht aus dem Grund heraus, dass beispielsweise beim Türöffnungsvorgang ein Hindernis auftaucht und der Türflügel mit dem Hindernis kollidieren könnte. Zu diesem Zweck sorgt die Blockiervorrichtung dafür, dass eine Kollision zwischen dem Türflügel und dem Hindernis verhindert wird. Schlussendlich wird im Stand der Technik nach der DE 10 2009 006946 A1 eine Türeinheit beschrieben, welche mit einer durch eine Feder vorgespannten Reibbremsvorrichtung ausgerüstet ist. Die Reibbremsvorrichtung dämpft Türbewegungen. Je nach von dem Türflügel absolvierten Stellweg baut die Feder eine unterschiedlich gestaltete Bremskraft auf. In addition, known from DE 10 2008 053 087 A1 such a door unit, in which the local coupling member acts as a braking device or blocking mechanism. The locking mechanism is used to lock the hinged door to a vehicle body. This happens for the reason that, for example, during the door opening process, an obstacle appears and the door could collide with the obstacle. For this purpose, the blocking device ensures that a collision between the door leaf and the obstacle is prevented. Finally, a door unit is described in the prior art according to DE 10 2009 006946 A1, which is equipped with a biased by a spring friction brake device. The friction brake device dampens door movements. Depending on the path completed by the door, the spring builds up a differently designed braking force.
Der Erfindung liegt das technische Problem zugrunde, eine derartige Türeinheit so weiter zu entwickeln, dass der Türflügel einwandfrei bewegt werden kann und The invention is based on the technical problem of further developing such a door unit so that the door leaf can be moved properly and
zugleich eine Fixierung bei Bedarf erfährt, wobei dies unter Berücksichtigung eines konstruktiv einfachen Aufbaus erreicht werden soll. at the same time learns a fixation if necessary, and this is to be achieved in consideration of a structurally simple structure.
Zu Lösung dieser technischen Problemstellung ist eine gattungsgemäße Türeinheit im Rahmen der Erfindung dadurch gekennzeichnet, dass das Kupplungsglied als in Abhängigkeit von der Drehgeschwindigkeit der Antriebswelle auslösbare Rutschkupplung ausgebildet ist. To solve this technical problem, a generic door unit in the invention is characterized in that the coupling member is formed as a function of the rotational speed of the drive shaft releasable slip clutch.
Die Erfindung greift also zunächst einmal auf ein als Rutschkupplung ausgebildetes Kupplungsglied zurück. Dabei erfolgt das Auslösen der Rutschkupplung überwiegend nicht drehmomentabhängig, sondern im Rahmen der Erfindung in Abhängigkeit von der Drehgeschwindigkeit der Antriebswelle. Anders ausgedrückt, sorgt die Antriebswelle des Bewegungsübertragungs- gliedes dafür, dass das als Rutschkupplung ausgebildete Kupplungsglied ausgelöst wird oder nicht. The invention thus first of all makes use of a coupling element designed as a sliding clutch. The triggering of the slip clutch is predominantly not dependent on the torque, but in the context of the invention as a function of the rotational speed of the drive shaft. In other words, the drive shaft of the Bewegungsübertragungs- member ensures that designed as a slip clutch coupling member is triggered or not.
Zu diesem Zweck ist die Rutschkupplung vorteilhaft mit wenigstens einem die Antriebswelle ganz oder teilweise umschließenden Reibelement ausgerüstet. Meistens sind sogar zwei Reibelemente realisiert. Dies lässt sich darauf zurückführen, dass die Antriebswelle regelmäßig unter Berücksichtigung zwei verschiedener Drehrichtungen rotiert. Diese beiden verschiedenen Drehrichtungen korrespondieren einerseits zu einer Öffnungsbewegung des Türflügels und andererseits zu einer Schließbewegung des Türflügels. In diesem Zusammenhang ist es sogar möglich und denkbar, das jeweilige Reibelement unterschiedlich auszulösen, d. h. unter Bercksichtigung verschiedener Schwellen für die Drehgeschwindigkeit der Antriebswelle. D. h., die Auslösung des Reibelementes im Zuge der Türöffnung mag mit einer For this purpose, the slip clutch is advantageously equipped with at least one friction element completely or partially enclosing the drive shaft. Mostly even two friction elements are realized. This can be attributed to the fact that the drive shaft rotates regularly taking into account two different directions of rotation. These two different directions of rotation correspond on the one hand to an opening movement of the door leaf and on the other hand to a closing movement of the door leaf. In this context, it is even possible and conceivable to trigger the respective friction element differently, ie, taking into account different thresholds for the rotational speed of the drive shaft. D. h., The release of the friction element in the course of the door opening may with a
anderen Drehgeschwindigkeit der Antriebswelle flankiert sein als dies im Falle einer Türschließung geschieht. be flanked other rotational speed of the drive shaft than this happens in the case of a door lock.
In jedem Fall hat es sich bewährt, wenn die Betätigung des Kupplungsgliedes bzw. der Rutschkupplung und folglich des Reibelementes damit einhergeht, dass das Reibelement von seinem Umschlingungsquerschnitt her veränderbar ausgelegt ist. Wird der Umschlingungsquerschnitt des Reibelementes verringert, so legt sich das Reibelement an die Antriebswelle an und umschließt diese ganz oder teilweise. Hierzu korrespondiert die eingerückte Position des Kupplungsgliedes und folglich der Rutschkupplung. Wird das Reibelement dagegen von seinem Umschlingungsquerschnitt her aufgeweitet, so kommt die zuvor festgehaltene Antriebswelle frei und kann im Anschluss hieran mehr oder minder frei rotieren. Dann ist die ausgerückte Stellung des Kupplungsgliedes und folglich der Rutschkupplung und damit des Reibelementes erreicht. In any case, it has proven useful if the operation of the coupling member or the slip clutch and consequently of the friction element is accompanied by the fact that the friction element is designed to be changeable from its wrap cross section. If the Umschlingungsquerschnitt of the friction element is reduced, so the friction element applies to the drive shaft and encloses this wholly or partially. For this purpose, the engaged position of the coupling member and consequently the slip clutch corresponds. If, however, the friction element is widened by its wrap-around cross-section, then the previously held drive shaft is released and can subsequently rotate more or less freely thereafter. Then the disengaged position of the coupling member and thus the slip clutch and thus the friction element is achieved.
Nach vorteilhafter Ausgestaltung ist das Reibelement zu diesem Zweck als in ihrem Durchmesser veränderbare Feder ausgebildet. Bei der besagten Feder kann es sich um eine Schlingfeder handeln. Eine solche Schlingfeder zeichnet sich durch einen wendelartigen Verlauf seiner Federwindungen ähnlich einer Schraubenfeder aus. Im Gegensatz zu einer Schraubenfeder kann eine Schlingfeder jedoch auch über einen nicht runden Federquerschnitt verfügen, ist dann vielmehr mit einem rechteckigen Federquerschnitt ausgerüstet. Dadurch kann die Breitseite des rechteckigen Federquerschnittes der von der Schlingfeder umschlossenen Antriebswelle zugewandt werden. Hierdurch lassen sich möglichst hohe Reibungskräfte zwischen Schlingfeder bzw. Reibelement und Antriebswelle übertragen. According to an advantageous embodiment, the friction element is designed for this purpose as variable in diameter spring. The said spring may be a wrap spring. Such a wrap spring is characterized by a helical course of its spring coils similar to a coil spring. In contrast to a helical spring, however, a wrap spring may also have a non-round spring cross-section, but rather is equipped with a rectangular spring cross-section. As a result, the broad side of the rectangular spring cross section of the enclosed by the wrap spring drive shaft are facing. As a result, the highest possible frictional forces between wrap spring and friction element and drive shaft can be transmitted.
Wie bereits erläutert, ist das Reibelement von seinem Umschlingungsquerschnitt her veränderbar ausgelegt und im Übrigen an die Antriebswelle angepasst. Da As already explained, the friction element is designed changeable from its Umschlingungsquerschnitt ago and adapted otherwise to the drive shaft. There
die Antriebswelle meistens zylindrisch ausgelegt ist, verfügt das Reibelement folgerichtig über einen bogenförmigen bzw. kreisförmigen Charakter, so dass die beschriebene Umschlingungs-querschnittänderung im Regelfall mit einer Durchmesseränderung des Reibelementes einhergeht. Um nun die Änderung des Umschlingungs-querschnitt bzw. des Durchmessers des Reibelementes zu bewirken, ist meistens ein Stellelement vorgesehen, welches mit dem Reibelement wechselwirkt. the drive shaft is usually designed cylindrical, the friction element has logically an arcuate or circular character, so that the described Umschlingungs cross-sectional change is usually accompanied by a change in diameter of the friction element. In order to effect the change of the wrap-cross-section or the diameter of the friction element, an adjusting element is usually provided, which interacts with the friction element.
Das Stellelement ist an die Antnebswelle angeschlossen. Folgerichtig steuert die Antriebswelle über das Stellelement das Reibelement. Je nach Drehgeschwindigkeit der Antriebswelle wird das Reibelement über das Stellelement mehr oder minder beaufschlagt. D. h., das Stellelement wechselwirkt mit dem Reibelement, und zwar nach Maßgabe der Drehgeschwindigkeit der Antriebswelle. The actuator is connected to the Antnebswelle. Consequently, the drive shaft controls the friction element via the adjusting element. Depending on the rotational speed of the drive shaft, the friction element is acted upon by the adjusting element more or less. D. h., The actuator interacts with the friction element, in accordance with the rotational speed of the drive shaft.
Es hat sich bewährt, mit zwei Reibelementen zu arbeiten, wobei jeweils ein Reibelement zu einer Drehrichtung der Antriebswelle korrespondiert. Da das Reibelement meistens als in ihrem Durchmesser veränderbare Feder ausgelegt ist, wird in diesem Fall üblicherweise mit zwei als Federn ausgebildeten Reibelementen gearbeitet. Zur Darstellung der unterschiedlichen Drehrichtungen der Antriebswelle und deren Berücksichtigung sind die beiden genannten Federn üblicherweise mit gegenläufigen Windungen ausgerüstet. Auf diese Weise wechselwirkt eine Feder mit einer Drehrichtung der Antriebswelle, wohingegen die andere Feder mit der anderen Drehrichtung der Antriebswelle zusammenwirkt. Das Stellelement trägt diesen beiden unterschiedlichen Drehrichtungen dadurch Rechnung, dass das an das Stellelement angeschlossene Stellglied je nach Drehrichtung der Antriebswelle entweder das eine Reibelement oder das andere Reibelement beaufschlagt. It has proven useful to work with two friction elements, wherein in each case a friction element corresponds to a direction of rotation of the drive shaft. Since the friction element is usually designed as a variable in diameter spring, it is usually worked in this case with two friction elements designed as springs. To illustrate the different directions of rotation of the drive shaft and their consideration, the two said springs are usually equipped with opposing turns. In this way, a spring interacts with a direction of rotation of the drive shaft, whereas the other spring interacts with the other direction of rotation of the drive shaft. The actuator carries these two different directions of rotation account for the fact that the actuator connected to the actuator depending on the direction of rotation of the drive shaft acts either one friction element or the other friction element.
In diesem Zusammenhang ist die Auslegung meistens so getroffen, dass das Stellelement nach Überschreiten einer vorgegebenen Drehgeschwindigkeit der Antriebswelle das Reibelement von der Antriebswelle löst. Wird die vorgegebene Drehgeschwindigkeit unterschritten, so legt das Stellelement das Reibelement an die Antriebswelle an. Wie bereits erläutert, ist das Stellelement mit einem Exzenter oder dergleichen Stellglied ausgerüstet. Mit Hilfe dieses Stellgliedes kann der Umschlingungsquerschnitt des Reibelementes verändert werden. Dabei ist die Auslegung meistens so getroffen, dass das Stellglied in zwei Drehrichtungen wirkt, und zwar der zugehörigen Drehrichtung der Antriebswelle folgend. Auf diese Weise kann ein und dasselbe Stellglied sowohl das Reibelement für die eine Drehrichtung als auch das Reibelement für die andere Drehrichtung in seinem Umschlingungsquerschnitt wie gewünscht verändern. In this context, the interpretation is usually made such that the actuator after exceeding a predetermined rotational speed of the drive shaft releases the friction element of the drive shaft. If the predetermined rotational speed is exceeded, the actuating element applies the friction element to the drive shaft. As already explained, the actuator is equipped with an eccentric or the like actuator. With the help of this actuator, the Umschlingungsquerschnitt the friction element can be changed. The design is usually made so that the actuator acts in two directions, namely the following direction of rotation of the drive shaft. In this way, one and the same actuator can change both the friction element for the one direction of rotation and the friction element for the other direction of rotation in its Umschlingungsquerschnitt as desired.
Um dies im Detail zu erreichen, greift das Stellelement im Regelfall an einem Ende des Reibelementes an. Das andere Ende des Reibelementes wird demgegenüber festgehalten. Da es sich bei dem Reibelement vorteilhaft um eine Feder handelt, greift das Stellelement an einem Federende an, während das andere Federende eine Fixierung erfährt. Sofern mit zwei Federn gearbeitet wird, und zwar einer Feder je Drehrichtung der Antriebswelle, ist die Auslegung so getroffen, dass die jeweils freien Enden der Federn zueinander benachbart sind. Auf diese Weise kann ein und dasselbe Stellglied zur Beaufschlagung der beiden freien Federenden herangezogen werden. In order to achieve this in detail, the actuating element usually engages at one end of the friction element. The other end of the friction element is held in contrast. Since it is advantageous in the friction element is a spring, the actuator engages at one end of the spring, while the other end of the spring undergoes a fixation. If you work with two springs, one spring per direction of rotation of the drive shaft, the interpretation is made such that the respective free ends of the springs are adjacent to each other. In this way, one and the same actuator can be used to act on the two free spring ends.
Bei dem Stellelement handelt es sich im Regelfall um eine drehbare Welle oder Stange, die üblicherweise mit einem Dämpfungselement ausgerüstet ist. Die drehbare Welle oder Stange taucht meistens in das fragliche Dämpfungselement ein. Das Dämpfungselement ist vorteilhaft mit einer Kammer ausgerüstet, die mit einem Viskosemedium gefüllt ist. An die Kammer ist das Stellglied angeschlossen. Bei dem Stellglied mag es sich um einen Exzenter oder auch The actuator is usually a rotatable shaft or rod, which is usually equipped with a damping element. The rotatable shaft or rod usually dips into the damping element in question. The damping element is advantageously equipped with a chamber which is filled with a viscous medium. The actuator is connected to the chamber. The actuator may be an eccentric or else
einen Nocken handeln, welcher typischerweise direkt oder unter Zwischenschaltung eines Stößels auf das jeweils freie Ende der Feder bzw. des Reibelementes arbeitet. Das ist selbstverständlich nur beispielhaft zu verstehen. Jedenfalls wird das Stellelement von der Antriebswelle direkt oder indirekt angetrieben und beaufschlagt. Sobald die Antriebswelle rotiert, erfährt auch das Stellelement im Regelfall eine Rotation. act a cam which typically works directly or with the interposition of a plunger on the respective free end of the spring or the friction element. This is of course only to be understood as an example. In any case, the actuator is directly or indirectly driven and acted upon by the drive shaft. As soon as the drive shaft rotates, the actuator also normally undergoes a rotation.
Je größer die Drehgeschwindigkeit der Antriebswelle ist, um so höher ist auch die Rotationsgeschwindigkeit des Stellelementes. Die Rotationsgeschwindigkeit des Stellelementes bzw. dessen Bewegungen werden durch das Dämpfungselement gedämpft. Ab einer bestimmten Drehgeschwindigkeit des Stellelementes wird die das Stellelement umschließende bzw. aufnehmende Kammer mit dem daran angeschlossenen Stellglied ausgelenkt. Dann ist die vorgegebene Drehgeschwindigkeit der Antriebswelle erreicht, welche dazu korrespondiert, dass das Reibelement von der Antriebswelle gelöst wird. The greater the rotational speed of the drive shaft, the higher the rotational speed of the actuating element. The rotational speed of the actuating element or its movements are damped by the damping element. From a certain rotational speed of the control element, the control element enclosing or receiving chamber is deflected with the actuator connected thereto. Then, the predetermined rotational speed of the drive shaft is reached, which corresponds to the fact that the friction element is released from the drive shaft.
Denn das ausgelenkte Stellglied sorgt seinerseits dafür, dass das freie Ende der Feder beaufschlagt wird. Da das dem freien Ende gegenüberliegende feste Ende der Feder fixiert ist, sorgt die Beaufschlagung des freien Endes der Feder dafür, dass die Feder die gewünschte Durchmessererweiterung erfährt. Als Folge hiervon wird die zuvor festgehaltene Antriebswelle freigegeben und kann unmittelbar und nahezu widerstandsfrei rotieren. Auf diese Weise kann die Rutschkupplung in Abhängigkeit von der Drehgeschwindigkeit der Antriebswelle ausgelöst werden. Sobald die besagte Drehgeschwindigkeit unterschritten wird, kann das Stellelement die Kammer und mit ihr das angeschlossene Stellglied nicht mehr im Sinne einer Drehung beaufschlagen, so dass das freie Ende der Feder keine Auslenkung mehr erfährt. Die Feder zieht sich zusammen und legt sich an die Antriebswelle an, welche im Anschluss hieran blockiert wird. Because the deflected actuator in turn ensures that the free end of the spring is acted upon. Since the free end of the opposite end of the spring is fixed, the application of the free end of the spring ensures that the spring undergoes the desired diameter extension. As a result, the previously held drive shaft is released and can rotate immediately and almost without resistance. In this way, the slip clutch can be triggered in response to the rotational speed of the drive shaft. Once the said rotational speed is exceeded, the actuator can no longer act on the chamber and with her the connected actuator in the sense of rotation, so that the free end of the spring experiences no deflection. The spring contracts and attaches itself to the drive shaft, which is subsequently blocked.
Im Ergebnis wird eine Türeinheit zur Verfügung gestellt, die mit einem speziellen Kupplungsglied veränderbarer Schließkraft ausgerüstet ist. Tatsächlich lässt sich das Kupplungsglied in Abhängigkeit von der Drehgeschwindigkeit der Antriebswelle auslösen. D. h., das Kupplungsglied bzw. die an dieser Stelle realisierte Rutschkupplung wird nach Maßgabe der Drehgeschwindigkeit der Antriebswelle entweder eingerückt oder ausgerückt. As a result, a door unit is provided, which is equipped with a special coupling member variable clamping force. In fact, the coupling member can be triggered in dependence on the rotational speed of the drive shaft. D. h., The coupling member or realized at this point slip clutch is either engaged or disengaged in accordance with the rotational speed of the drive shaft.
Überschreitet die Antriebswelle die vorgegebene Drehgeschwindigkeit, so wird das Kupplungsglied bzw. die Rutsch kupplung ausgerückt und gibt die zuvor festgehaltene Antriebswelle frei. Diese kann folglich widerstandsfrei oder nahezu ohne Widerstand rotieren. Wird jedoch die vorgegebene Drehgeschwindigkeit der Antriebswelle unterschritten, so wird die Freigabe der Rutschkupplung aufgehoben und die Rutschkupplung rückt ein. Als Folge hiervon wird die Antriebswelle blockiert. Exceeds the drive shaft, the predetermined rotational speed, the coupling member or the slip clutch is disengaged and releases the previously held drive shaft. This can consequently rotate without resistance or with almost no resistance. However, if the predetermined rotational speed of the drive shaft is exceeded, the release of the slip clutch is released and the slip clutch engages. As a result, the drive shaft is blocked.
Die frei rotierende Antriebswelle korrespondiert dazu, dass der hiermit wechselwirkende Türflügel der Türeinheit problemlos hin- und herbewegt werden kann. Dazu ist eine bestimmte Geschwindigkeit der Schwenkbewegung des Türflügels erforderlich, die dazu korrespondiert, dass die Antriebswelle die vorgegebene Drehgeschwindigkeit überschreitet. Wird jedoch der Türflügel mit einer geringeren Schwenkgeschwindigkeit bewegt, so fällt auch die Geschwindigkeit der Antriebswelle unter die vorgegebene Drehgeschwindigkeit und der Türflügel erfährt eine Blockade. Das alles lässt sich besonders kostengünstig, einfach und ohne zusätzliche elektrische oder mechanische Glieder komplizierten Aufbaus erreichen. Hierin sind die wesentlichen Vorteile zu sehen. The freely rotating drive shaft corresponds to the fact that the hereby interactive door leaf of the door unit can be easily moved back and forth. For this purpose, a certain speed of the pivoting movement of the door leaf is required, which corresponds to the fact that the drive shaft exceeds the predetermined rotational speed. However, if the door is moved at a lower swing speed, so does the speed of the drive shaft below the predetermined rotational speed and the door undergoes a blockage. All this can be achieved particularly cost-effectively, simply and without additional electrical or mechanical links of complicated structure. Here are the main benefits.
Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert; es zeigen: In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment; show it:
Fig. 1 Eine erfindungsgemäße Türeinheit schematisch, 1 is a door unit according to the invention schematically,
Fig. 2 das Kupplungsglied in einer Übersicht, 2 shows the coupling member in an overview,
Fig. 3 einen Detailausschnitt aus der Fig. 2 im Rahmen einer abgewandelten Ausführungsform und Fig. 3 shows a detail of the Fig. 2 in a modified embodiment and
Fig. 4 einen schematischen Querschnitt durch den Gegenstand nach Fig. 2 entlang einer Linie A-A. Fig. 4 is a schematic cross-section through the article according to Fig. 2 along a line A-A.
In der Fig. 1 ist eine Türeinheit dargestellt, bei welcher es sich im Ausführungsbeispiel um eine Kraftfahrzeugtüreinheit handelt. Diese verfügt über einen Türflügel 1 , welcher in einem Drehpunkt 2 an eine Kraftfahrzeugkarosserie angelenkt ist und sich um diesen Drehpunkt 2 in der durch einen Doppelpfeil angedeuteten Schwenkrichtung öffnen und schließen lässt. Bei diesem Vorgang wird eine Schwenkbewegung s mit einer bestimmten Schwenkgeschwindigkeit s absolviert. In Fig. 1, a door unit is shown, in which it is a motor vehicle door unit in the embodiment. This has a door 1, which is articulated in a pivot point 2 to a motor vehicle body and can be opened and closed about this pivot point 2 in the direction indicated by a double arrow pivoting direction. In this process, a pivoting movement s is completed with a certain swinging speed s.
Durch die Schwenkbewegung s wird eine Zahnstange 3 hin und herbewegt, die an den Türflügel 1 angeschlossen ist. Linearbewegungen der Zahnstange 3 werden auf eine Antriebswelle 4 übertragen. Die Zahnstange 3 und die Antriebswelle 4 fungieren zusammengenommen als Bewegungsübertragungsglied 3, 4, welches an den Türflügel 1 angeschlossen ist. Je größer die Schwenkgeschwindigkeit S ausgelegt ist, um so größer ist folgerichtig auch die Drehgeschwindigkeit der Antriebswelle 4. By the pivoting movement s a rack 3 is moved back and forth, which is connected to the door 1. Linear movements of the rack 3 are transmitted to a drive shaft 4. The rack 3 and the drive shaft 4 act together as a motion transmission member 3, 4, which is connected to the door leaf 1. The greater the pivoting speed S is designed, the greater is logically the rotational speed of the drive shaft 4th
Von der Antriebswelle 4 wird ein schematisch in der Fig. 2 näher dargestelltes Kupplungsglied 5 veränderbarer Schließkraft beaufschlagt. Tatsächlich lässt sich das Kupplungsglied 5 im Wesentlichen einrücken und ausrücken. Die eingerückte Stellung des Kupplungsgliedes 5 korrespondiert dazu, dass das Kupplungsglied 5 die Antriebswelle 4 festhält. Dagegen korrespondiert die ausgerückte Stellung des Kupplungsgliedes 5 dazu, dass die Antriebswelle 4 vom Kupplungsglied 5 freigegeben wird und widerstandsfrei oder nahezu widerstandsfrei rotiert. Anhand der Darstellung nach Fig. 2 erkennt man, dass das Kupplungsglied 5 als Rutschkupplung 5 ausgebildet ist. Dabei wird das Kupplungsglied 5 bzw. die Rutschkupplung 5 in Abhängigkeit von der Drehgeschwindigkeit der Antriebswelle 4 ausgelöst. Überscheitet die Drehgeschwindigkeit der Antriebswelle 4 eine vorgegebene Drehgeschwindigkeit, so wird das Kupplungsglied 5 ausgerückt und gibt die Antriebswelle 4 frei. Bei Unterschreiten der vorgegebenen Drehgeschwindigkeit wird das Kupplungsglied 5 bzw. die Rutschkupplung 5 eingerückt und hält die Antriebswelle 4 frei. Zu diesem Zweck ist die Rutschkupplung 5 mit wenigstens einem die Antriebswelle 4 ganz oder teilweise umschließenden Reibelement 6, 7 ausgerüstet. From the drive shaft 4, a schematically shown in Fig. 2 in more detail coupling member 5 is applied variable clamping force. In fact, the coupling member 5 can be substantially engaged and disengaged. The engaged position of the coupling member 5 corresponds to the fact that the coupling member 5, the drive shaft 4 holds. In contrast, the disengaged position of the coupling member 5 corresponds to the fact that the drive shaft 4 is released from the coupling member 5 and rotates without resistance or almost without resistance. Based on the illustration of FIG. 2 it can be seen that the coupling member 5 is formed as a slip clutch 5. In this case, the coupling member 5 and the slip clutch 5 is triggered in response to the rotational speed of the drive shaft 4. If the rotational speed of the drive shaft 4 exceeds a predetermined rotational speed, the coupling member 5 is disengaged and releases the drive shaft 4. When falling below the predetermined rotational speed, the coupling member 5 and the slip clutch 5 is engaged and keeps the drive shaft 4 free. For this purpose, the slip clutch 5 is equipped with at least one drive element 4 completely or partially enclosing friction element 6, 7.
Tatsächlich sind im Rahmen des Ausführungsbeispiels zwei Reibelemente 6, 7 vorgesehen. Dabei gehört das eine Reibelement 6 zu einer Drehrichtung der Antriebswelle 4, vorliegend deren Drehung im Uhrzeigersinn. Dagegen gehört das andere Reibelement 7 zu einer Gegenuhrzeigersinndrehung der Antriebs- welle 4. In fact, two friction elements 6, 7 are provided in the context of the embodiment. This includes a friction element 6 to a rotational direction of the drive shaft 4, in this case, their rotation in a clockwise direction. By contrast, the other friction element 7 belongs to a counterclockwise rotation of the drive shaft 4.
Beide Reibelemente 6, 7 sind von ihrem Umschlingungsquerschnitt her veränderbar ausgelegt. Bei dem jeweiligen Reibelement 6, 7 handelt es sich um eine in ihrem Durchmesser veränderbare Feder 6, 7. Tatsächlich ist das jeweilige Both friction elements 6, 7 are designed to be changeable from their Umschlingungsquerschnitt forth. The respective friction element 6, 7 is a variable in diameter diameter spring 6, 7. Actually, the respective
Reibelement 6, 7 im Rahmen des Ausführungsbeispiels als Schlingfeder 6, 7 ausgelegt. Die Schlingfeder 6, 7 verfügt über einen rechteckigen Federquerschnitt, wobei die größte Breite des rechteckigen Federquerschnittes der Antriebswelle 4 zugewandt ist. Dadurch lassen sich maximale Reibungskräfte auf die Antriebswelle 4 seitens der Feder 6, 7 übertragen. Man erkennt, dass die beiden Federn 6, 7 mit gegenläufigen Windungen ausgerüstet sind. Jede Feder 6, 7 verfügt über ein jeweils festes Ende 6a, 7a und ein freies Ende 6b, 7b. Dadurch, dass die beiden Federn 6, 7 mit gegenläufigen Windungen ausgerüstet sind, lässt sich die Auslegung so treffen, dass die jeweils festen Enden 6a, 7a über einen maximalen Abstand zueinander verfügen, wohingegen die freien Enden 6b, 7b in unmittelbarer Nachbarschaft zueinander angeordnet sind. Auf diese Weise besteht die Möglichkeit, das jeweilige Reibelement 6, 7 mit einem einzigen Stellelement 8 zu beaufschlagen. Friction element 6, 7 in the embodiment designed as a wrap spring 6, 7. The wrap spring 6, 7 has a rectangular spring cross-section, wherein the largest width of the rectangular spring cross-section of the drive shaft 4 faces. As a result, maximum friction forces can be transmitted to the drive shaft 4 by the spring 6, 7. It can be seen that the two springs 6, 7 are equipped with opposing turns. Each spring 6, 7 has a respective fixed end 6a, 7a and a free end 6b, 7b. Characterized in that the two springs 6, 7 are equipped with opposing turns, the interpretation can be such that the respective fixed ends 6a, 7a have a maximum distance from each other, whereas the free ends 6b, 7b are arranged in close proximity to each other , In this way it is possible to apply the respective friction element 6, 7 with a single actuator 8.
Das Stellelement 8 ist an die Antriebswelle 4 angeschlossen, und zwar im Rahmen des Ausführungsbeispiels unter Zwischenschaltung eines Dämpfungselementes 9. Außerdem verfügt das Stellelement 8 über einen Anschluss zu einem Stellglied 11. In diesem Zusammenhang ist die Auslegung so getroffen, dass das Stellelement 8 jeweiligen Rotationen der Antriebswelle 4 im Gegenuhrzeigersinn und im Uhrzeigersinn folgt und auch folgen kann. Dagegen vollführt das Stellglied 11 nur Drehungen oder Schwenkbewegungen im Gegenuhrzeigersinn, wie ein entsprechender Pfeil in Fig. 4 deutlich macht. Zu diesem Zweck ist zwischen dem Stellelement 8 und dem Stellglied 11 ein nicht näher dargestelltes Übertragungsglied zwischengeschaltet, welches Uhrzeigersinnbewegungen des Stellelementes 8 in solche im Gegenuhrzeigersinn des Stellgliedes 11 umwandelt, so dass das Stellglied 11 lediglich die bereits angesprochenen Drehungen im Gegenuhrzeigersinn vollführt. The actuator 8 is connected to the drive shaft 4, in the context of the embodiment with the interposition of a damping element 9. In addition, the actuator 8 has a connection to an actuator 11. In this context, the design is such that the actuator 8 respective rotations the drive shaft 4 counterclockwise and clockwise follows and can follow. In contrast, the actuator 11 performs only rotations or pivotal movements in the counterclockwise direction, as a corresponding arrow in Fig. 4 makes clear. For this purpose, an unspecified transfer member is interposed between the adjusting element 8 and the actuator 11, which converts clockwise movements of the adjusting element 8 in such a counterclockwise direction of the actuator 11, so that the actuator 11 performs only the already mentioned rotations counterclockwise.
Das Dämpfungselement 9 besitzt eine Kammer 10, die ein Viskosemedium im Innern aufnimmt. Je nach dem, wie stark die Antriebswelle 4 rotiert, wird das im Innern der Kammer 10 befindliche Viskosemedium mehr oder minder "mitge- nommen" und sorgt ab einer bestimmten und vorgegebenen Drehgeschwindigkeit der Antriebswelle 4 dafür, dass die Kammer 10 eine Auslenkung erfährt. In gleicher Weise wird auch das Stellelement 8 ausgelenkt und erfährt das mit dem Stellelement 8 indirekt über das Übertragungsglied verbundene Stellglied 11 eine Beaufschlagung. Bei dem Stellglied 11 handelt es sich im Rahmen des Ausführungsbeispiels nach der Fig. 4 um einen Doppelnocken. The damping element 9 has a chamber 10 which receives a viscous medium in the interior. Depending on how strongly the drive shaft 4 rotates, the viscous medium located in the interior of the chamber 10 is more or less "entrained" and, at a certain and predetermined rotational speed of the drive shaft 4, ensures that the chamber 10 undergoes a deflection. In the same way, the adjusting element 8 is deflected and undergoes the actuator 11 indirectly connected via the transmission member actuator 11, an application. The actuator 11 is in the context of the embodiment of FIG. 4 to a double cam.
Das Stellglied 11 bzw. der Doppelnocken 11 arbeitet auf Stößel 12, die jeweils das freie Ende 6b einerseits der Feder 6 bzw. 7b andererseits der Feder 7 auslenken. Tatsächlich führt eine Drehung des Stellgliedes bzw. Doppelnockens 11 in jeder Drehrichtung des Stellelementes 8 dazu, dass das freie Ende 6b der Feder 6 und das freie Ende 7b der Feder 7 von dem Stößel 12 beaufschlagt werden und zu einer in der Fig. 4 angedeuteten Durchmesservergrößerung der zugehörigen Feder 6, 7 korrespondieren. Diese Durchmesservergrößerung der Feder 6, 7 führt dazu, dass die zuvor von der Feder 6, 7 führt dazu, dass die zuvor von der Feder 6, 7 festgehaltene An ebswelle 4 freigegeben wird. The actuator 11 and the double cam 11 operates on plunger 12, each deflecting the free end 6 b of the spring 6 and 7 b on the other hand, the spring 7. In fact, a rotation of the actuator or double cam 11 in each direction of rotation of the adjusting element 8 causes the free end 6b of the spring 6 and the free end 7b of the spring 7 are acted upon by the plunger 12 and a diameter increase indicated in FIG the associated spring 6, 7 correspond. This increase in diameter of the spring 6, 7 causes the previously of the spring 6, 7 causes the previously held by the spring 6, 7 is on ebswelle 4 is released.
Die Fig. 3 stellt eine etwas abgewandelte Ausführungsform dar, bei welcher eine Feder 6 zwischen einerseits der Antriebswelle 4 und andererseits einem feststehenden Gehäuse 13 zwischengeschaltet ist. Wird die Feder 6 von ihrem Durchmesser her vergrößert, so legt sie sich außenseitig an das feststehende und die Feder 6 umschließende Gehäuse 13 an. Geschieht dies über die gesamte Länge der Feder 6, so wird als Folge hiervon die zuvor von der Feder 6 festgehaltene und umschlossene Antriebswelle 4 freigegeben. Kommt es dagegen nur teilweise zu einer Durchmesservergrößerung entlang der Länge der Fig. 3 illustrates a somewhat modified embodiment, in which a spring 6 between the one hand, the drive shaft 4 and on the other hand, a fixed housing 13 is interposed. If the spring 6 is increased in diameter, it settles on the outside against the fixed housing 6 enclosing the spring 6. If this happens over the entire length of the spring 6, as a result of this, the previously held by the spring 6 and enclosed drive shaft 4 is released. If, however, it only partially to an increase in diameter along the length of the
Feder 6, so sorgt die Feder 6 für eine mechanische Kopplung zwischen dem feststehenden Gehäuse 13 und der rotierenden Antriebswelle 4. Hierzu korrespondiert ein Durchrutschen der auf diese Weise realisierten Rutschkupplung 5. Spring 6, so provides the spring 6 for a mechanical coupling between the fixed housing 13 and the rotating drive shaft 4. For this corresponds to slipping of the realized in this way slip clutch. 5
Die prinzipielle Funktionsweise ist wie folgt. Sobald der Türflügel 1 eine Schwenkbewegung s vollführt, wird die Antriebswelle 4 rotiert. Dabei müssen zunächst Reibungskräfte der beiden Reibelemente bzw. Federn 6, 7 überwunden werden. Die Antriebswelle 4 rotiert auch innerhalb der Kammer 10. Diese Rotationen führen allerdings nicht dazu, dass die Kammer 10 und auch das an die Kammer 10 angeschlossene Stellelement 8 eine Drehung erfahren. Tatsächlich handelt es sich bei dem Stellelement 8 im Rahmen des Ausführungsbeispiels um eine drehbare Welle oder Stange. Überschreitet jedoch die Schwenkgeschwindigkeit S des Türflügels 1 bzw. die damit zusammenhängende Drehgeschwindigkeit der Antriebswelle 4 einen vorgegebenen Wert, so ist die Antriebswelle 4 unter Zwischenschaltung des Dämpfungselementes 9 in der Lage, die Kammer 10 zu rotieren. Die rotierende Kammer 10 sorgt über das Stellelement 8 und das indirekt daran angeschlossene Stellglied 11 dafür, dass auch das betreffende Stellglied 11 bzw. der zugehörige Doppelnocken 11 eine Rotation im Gegen Uhrzeigersinn erfährt. Diese Rotation ist in der Fig. 4 durch einen Pfeil angedeutet und führt dazu, dass von den beiden Nocken die beiden Stößel 2 beaufschlagt werden. Da die beiden Stößel 12 die jeweils freien Federenden 7b bzw. 6b der zugehörigen Federn 6, 7 auslenken, erfahren die beiden Federn 6, 7 eine Durchmesservergrößerung. Die Durchmesservergrößerung der Federn 6, 7 führt dazu, dass die zuvor festgehaltene Antriebswelle 4 nicht (mehr) von den Federn The basic mode of operation is as follows. As soon as the door leaf 1 performs a pivoting movement s, the drive shaft 4 is rotated. At first friction forces of the two friction elements or springs 6, 7 must be overcome. The drive shaft 4 also rotates within the chamber 10. However, these rotations do not cause the chamber 10 and also the adjoining the chamber 10 actuator 8 undergo a rotation. In fact, the adjusting element 8 in the exemplary embodiment is a rotatable shaft or rod. However, if the pivoting speed S of the door leaf 1 or the associated rotational speed of the drive shaft 4 exceeds a predetermined value, the drive shaft 4 with the interposition of the damping element 9 in a position to rotate the chamber 10. The rotating chamber 10 ensures via the actuator 8 and the indirectly connected thereto actuator 11 that even the relevant actuator 11 and the associated double cam 11 undergoes a counterclockwise rotation. This rotation is indicated in Fig. 4 by an arrow and causes the two tappets 2 are acted upon by the two cams. Since the two plungers 12 deflect the respective free spring ends 7b and 6b of the associated springs 6, 7, the two springs 6, 7 experience an increase in diameter. The increase in diameter of the springs 6, 7 causes the previously held drive shaft 4 not (more) of the springs
6, 7 festgehalten wird und frei rotieren kann. Als Folge hiervon lässt sich der Türflügel 1 nahezu widerstandsfrei hin und her bewegen. 6, 7 is held and can rotate freely. As a result of this, the door leaf 1 can be moved back and forth with almost no resistance.
Die beiden freien Federenden 6b, 7b sind jeweils mit Hilfe eines verstellbaren Anschlages 14 fest in dem zugehörigen Gehäuse 13 eingespannt bzw. am Türflügel 1 festgelegt. Mit Hilfe des jeweiligen Anschlages 14 kann zusätzlich ein Drehmoment vorgegeben werden, gegen welches die Stößel 12 arbeiten müssen, um das jeweils freie Federende 6b, 7b auslenken zu können und folglich die gewünschte Durchmesservergrößerung der Feder 6, 7 zu bewirken. Dadurch lassen sich nicht nur Vorgaben hinsichtlich der erforderlichen Drehgeschwindigkeit der Antriebswelle 4 zum Auslösen des Kupplungsgliedes bzw. der Rutschkupplung 5 realisieren, sondern auch dahingehend, dass seitens der Antriebswelle 4 und folglich des damit zusammenwirkenden Türflügels 1 ein bestimmtes Mindestdrehmoment überschritten werden muss. D. h. , nach vorteilhafter Ausgestaltung lässt sich das Kupplungsglied nicht nur in Abhängigkeit von der Drehgeschwindigkeit der Antriebswelle 4 auslösen, sondern zusätzlich und ergänzend noch in Abhängigkeit eines Drehmomentes, welches letztlich mit Hilfe der beiden Anschläge 14 vorgegeben wird. The two free spring ends 6b, 7b are each fixed by means of an adjustable stop 14 in the associated housing 13 and fixed to the door leaf 1. With the help of the respective stop 14, a torque can additionally be preset, against which the plunger 12 must work in order to deflect the respective free spring end 6b, 7b and consequently to effect the desired increase in the diameter of the spring 6, 7. As a result, it is not only possible to implement specifications with regard to the required rotational speed of the drive shaft 4 for triggering the coupling member or the slip clutch 5, but also to the effect that a certain minimum torque must be exceeded by the drive shaft 4 and consequently the door leaf 1 interacting therewith. Ie. , According to an advantageous embodiment, the coupling member can be triggered not only in dependence on the rotational speed of the drive shaft 4, but additionally and additionally depending on a torque, which is ultimately determined by means of the two stops 14.
