Definitions
- the present invention relates to a drive device for driving an element with a toothed belt, a toothed disc and an at least partially non-linear guideway, in which the element is guided via a guide means.
- Timing belts usually have a smooth side and a side with teeth. Usually, the smooth side is outside, while the inside of the belt is provided with the teeth.
- the toothed belt encloses the toothed disc, wherein the teeth of the toothed belt engage in tooth recesses of the toothed disc, so that the toothed disc drives the toothed belt over the tooth recesses and teeth.
- Timing belt drives are often used for the transport of horizontally transported or moving objects.
- toothed belt drives also serve as door drives for opening and closing vehicle doors, in particular for doors of vehicles of public local and long-distance traffic.
- toothed pulleys Often, only one of the toothed pulleys is driven in a rotating toothed belt drive, while the other or more toothed pulleys only run along and deflect the toothed belt.
- connection of the elements to be conveyed or transported to the toothed belt takes place, for example, via drivers. Often problems arise in that the attachment of the driver on the timing belt is not sufficient to transmit high driving forces.
- the drivers solve due to peak loads or during operation, which causes repair costs and costs.
- Timing belts are usually made of plastic material that is reinforced by longitudinal cables or wires. The essential for absorbing the tensile forces ropes or wires must not by attaching the driver damaged, otherwise the stability and tear resistance of the toothed belt is impaired. This also limits the power transmission to be driven or entrained elements via drivers.
- Another problem is that a force transmission takes place only along the longitudinal extension of the toothed belt, ie in the x direction.
- a deflection of the element driven by the driver for example via guide rails is possible, but causes a high loss of drive energy by dividing the introduction of force into an x-component, (parallel to the direction of movement of the toothed belt) and a y-component (transverse to the direction of movement of the toothed belt ).
- the object of the present invention is to avoid the above-mentioned disadvantages of the prior art by an improved drive device for driving an element which has a toothed belt drive.
- the drive device should improve the use of drive energy and ensure a durable and low-maintenance operation of the belt drive.
- the object is achieved by a drive device, comprising the features of the independent claim.

- the force originating from the toothed belt drive is optimally transferred to the element to be driven even if it is deflected out of the straight guide track in another direction via the at least one toothed disk of the drive according to the invention.
- the drive device therefore has at least one toothed disc with tooth recesses for entrainment of teeth of the toothed belt and Kraftmit psychologyaussparungen for entrainment of the at least one Kraftmit supplementss, which usually does not drive, but only deflects the timing belt.
- this toothed disk can also be designed as a driving toothed disk. Then, the driving force is transmitted from the toothed pulley to the toothed belt or the driven element not only on the teeth of the toothed belt, but also on the at least one Kraftmit facilitator, which is in corresponding Kraftmit gestaussparitch the toothed wheel. As a result, if necessary. Even larger forces can be transmitted.
- the force transducer is fastened exclusively by clamping on the toothed belt.
- the clamping connection has the significant advantage that the structure of the toothed belt is not changed by the attachment.

- the lower part may have a serrated contour in which teeth of the toothed belt come to rest. This leads to a form-locking connection of Kraftmit ceremonies with the timing belt.
- connection of the top and the bottom can be made by any suitable means. It has proved to be advantageous if the power cam has a length which exceeds a width of the toothed belt (transverse to the longitudinal extent).
- the length of the Kraftmit clergy is arranged in a state attached to the toothed belt transversely to the direction or longitudinal extension of the toothed belt.
- Connecting elements, such as screws connect the upper part with the lower part, wherein the screws are arranged laterally of the toothed belt and not penetrate.
- the power cam also forms a connecting element, which is connectable to the driven element.
- a projection is provided, which is connectable to the driving element or an additional intermediate connecting element.
- Such a supernatant may be formed for example by a cylindrical stub axle.
- a stub axle is particularly suitable because it allows a pivotal or rotatable connection with the element to be driven or the interposed intermediate connecting element.
- the pivoting or rotation between the connecting element and the element to be driven is necessary in order to be able to guide the driven element along the circumference of the toothed disk when it deflects the power take-off.

- the power cam is designed as a substantially cylindrical element, wherein a lateral projection over the width of the toothed belt, so an end-side stub axle serves as a connecting element.
- the power cam may have only a single connecting element on one side of the toothed belt or two connecting elements on both sides of the toothed belt.
- the power transmission to the driven element can be further improved by arranging a plurality of force drivers side by side on the toothed belt, which are connected to a single element to be driven.
- An additional connecting plate connects the at least two Kraftmit facilitator such that tensile forces can be transmitted from a Kraftmit commentary on the adjacent Kraftmit repertoire via the connecting plate.
- the connecting plate must be pivotally or rotatably attached to one of the two power users for this purpose and preferably has a curved slot into which a power transmission section of the adjacent Kraftmit ceremonies extends.
- the power transmission section may be formed by the connecting element, that is, for example, by a stub axle, which extends through the curved slot.

- an odd number of Kraftmitsupplementaryn may be provided, which are interconnected via the connecting plate.
- the connecting plate is pivotally or rotatably mounted on the middle Kraftmitnado-inducible substance, wherein force transmission sections of the adjacent Kraftmitsupplementary extend into corresponding curved slots. Only the middle power cam is connected via its connecting element with the element to be driven, so that occurring forces are distributed over the connecting plate on all connected Kraftmitsupplementary.
- the tension within the toothed belt does not increase as a result of the connection of the force drivers with one another when in contact with the toothed disk.
- the guide track has an arcuate track section, so that the power cam is moved around the toothed disc in such a way that an over-center position results.
- the guide track has a first straight track section, a second straight track section and an arcuate end track section, wherein the two straight track sections are arranged at an angle to each other.

Description
Die vorliegende Erfindung betrifft eine Antriebsvorrichtung zum Antrieb eines Elements mit einem Zahnriemen, einer Zahnscheibe und einer zumindest abschnittsweise nichtlinearen Führungsbahn, in der das Element über ein Führungsmittel geführt ist.The present invention relates to a drive device for driving an element with a toothed belt, a toothed disc and an at least partially non-linear guideway, in which the element is guided via a guide means.
Zahnriemen weisen meist eine glatte Seite und eine Seite mit Zähnen auf. Üblicherweise befindet sich die glatte Seite außen, während die Innenseite des Zahnriemens mit den Zähnen versehen ist. Der Zahnriemen umschließt dabei die Zahnscheibe, wobei die Zähne des Zahnriemens in Zahnaussparungen der Zahnscheibe eingreifen, so dass die Zahnscheibe den Zahnriemen über die Zahnaussparungen und Zähne antreibt.Timing belts usually have a smooth side and a side with teeth. Usually, the smooth side is outside, while the inside of the belt is provided with the teeth. The toothed belt encloses the toothed disc, wherein the teeth of the toothed belt engage in tooth recesses of the toothed disc, so that the toothed disc drives the toothed belt over the tooth recesses and teeth.
Zahnriemenantriebe werden oftmals für den Transport von horizontal zu transportierenden oder zu bewegenden Gegenständen verwendet. Insbesondere dienen Zahnriemenantriebe auch als Türantriebe zum Öffnen und Schließen von Fahrzeugtüren, insbesondere für Türen von Fahrzeugen des öffentlichen Nah- und Fernverkehrs.Timing belt drives are often used for the transport of horizontally transported or moving objects. In particular, toothed belt drives also serve as door drives for opening and closing vehicle doors, in particular for doors of vehicles of public local and long-distance traffic.
Oftmals ist bei einem umlaufenden Zahnriemenantrieb nur eine der Zahnscheiben angetrieben, während die andere oder auch mehrere Zahnscheiben lediglich mitlaufen und den Zahnriemen umlenken.Often, only one of the toothed pulleys is driven in a rotating toothed belt drive, while the other or more toothed pulleys only run along and deflect the toothed belt.
Die Anbindung der zu fördernden bzw. zu transportierenden Elemente an den Zahnriemen erfolgt beispielsweise über Mitnehmer. Oftmals ergeben sich Probleme dadurch, dass die Befestigung der Mitnehmer am Zahnriemen nicht ausreicht, um hohe Antriebskräfte zu übertragen. Die Mitnehmer lösen sich aufgrund von Belastungsspitzen oder im Laufe des Betriebs, was Reparaturaufwand und Kosten verursacht.The connection of the elements to be conveyed or transported to the toothed belt takes place, for example, via drivers. Often problems arise in that the attachment of the driver on the timing belt is not sufficient to transmit high driving forces. The drivers solve due to peak loads or during operation, which causes repair costs and costs.
Zahnriemen bestehen üblicherweise aus Kunststoffmaterial, das durch längs verlaufende Seile oder Drähte verstärkt ist. Die zur Aufnahme der Zugkräfte wesentlichen Seile oder Drähte dürfen durch das Anbringen der Mitnehmer nicht beschädigt werden, da ansonsten die Stabilität und Reißfestigkeit des Zahnriemens beeinträchtigt wird. Auch hierdurch ist die Kraftübertragung auf anzutreibende oder mitzunehmende Elemente über Mitnehmer begrenzt.Timing belts are usually made of plastic material that is reinforced by longitudinal cables or wires. The essential for absorbing the tensile forces ropes or wires must not by attaching the driver damaged, otherwise the stability and tear resistance of the toothed belt is impaired. This also limits the power transmission to be driven or entrained elements via drivers.
Ein weiteres Problem besteht darin, dass eine Kraftübertragung nur entlang der Längserstreckung des Zahnriemens, also in x-Richtung erfolgt. Eine Umlenkung des über Mitnehmer angetriebenen Elements beispielsweise über Führungsschienen ist zwar möglich, verursacht aber einen hohen Verlust an Antriebsenergie durch die Aufteilung der Krafteinleitung in eine x-Komponente, (parallel zur Bewegungsrichtung des Zahnriemens) und eine y-Komponente (quer zur Bewegungsrichtung des Zahnriemens).Another problem is that a force transmission takes place only along the longitudinal extension of the toothed belt, ie in the x direction. Although a deflection of the element driven by the driver, for example via guide rails is possible, but causes a high loss of drive energy by dividing the introduction of force into an x-component, (parallel to the direction of movement of the toothed belt) and a y-component (transverse to the direction of movement of the toothed belt ).
Dieses Problem ergibt sich z.B. bei Schwenkschiebetüren, die parallel und abschnittsweise schräg zur Fahrzeugaußenwand verschoben werden und in einer gekrümmt verlaufenden Führungsbahn geführt sind. Der Antrieb erfolgt über einen Zahnriemenantrieb, wobei die Tür über einen Mitnehmer mit dem Zahnriemen verbunden ist. Aufgrund des geraden Verlaufs des Zahnriemens wird die Antriebskraft nur in eine Richtung (x-Richtung) eingeleitet, aber im Bewegungsverlauf aufgrund der gekrümmt verlaufenden Führungsschiene in eine x-Komponente und eine y-Komponente (quer zur x-Richtung) aufgeteilt. Durch diese Aufteilung ergeben sich erhebliche Verluste der Antriebsenergie. Ein solcher Antrieb mit den genannten Nachteilen ist in der
Die Aufgabe der vorliegenden Erfindung besteht darin, die oben genannten Nachteile des Standes der Technik durch eine verbesserte Antriebsvorrichtung zum Antrieb eines Elements, die einen Zahnriemenantrieb aufweist, zu vermeiden. Insbesondere soll die Antriebsvorrichtung die Nutzung der Antriebsenergie verbessern und einen dauerhaften und wartungsarmen Betrieb des Zahnriemenantriebs gewährleisten.The object of the present invention is to avoid the above-mentioned disadvantages of the prior art by an improved drive device for driving an element which has a toothed belt drive. In particular, the drive device should improve the use of drive energy and ensure a durable and low-maintenance operation of the belt drive.
Erfindungsgemäß wird die Aufgabe durch eine Antriebsvorrichtung gelöst, aufweisend die Merkmale des unabhängigen Anspruchs.According to the invention the object is achieved by a drive device, comprising the features of the independent claim.
Die erfindungsgemäße Antriebsvorrichtung eignet sich insbesondere für einen Antrieb von Schwenkschiebetüren oder ähnlichen Elementen, wie Fenstern oder Klappen. Die vom Zahnriemenantrieb stammende Kraft wird dabei auch dann optimal auf das anzutreibende Element übertragen, wenn dieses über die mindestens eine Zahnscheibe des erfindungsgemäßen Antriebs aus der geraden Führungsbahn heraus in eine andere Richtung umgelenkt wird.The drive device according to the invention is particularly suitable for driving sliding sliding doors or similar elements, such as windows or flaps. The force originating from the toothed belt drive is optimally transferred to the element to be driven even if it is deflected out of the straight guide track in another direction via the at least one toothed disk of the drive according to the invention.
Die Antriebsvorrichtung weist demnach mindestens eine Zahnscheibe mit Zahnaussparungen zur Mitnahme von Zähnen des Zahnriemens und Kraftmitnehmeraussparungen zur Mitnahme des mindestens einen Kraftmitnehmers auf, die üblicherweise nicht antreibt, sondern den Zahnriemen lediglich um lenkt. Im Rahmen der Erfindung kann aber auch diese Zahnscheibe als antreibende Zahnscheibe ausgelegt sein. Dann wird die Antriebskraft von der Zahnscheibe auf den Zahnriemen bzw. das anzutreibende Element nicht nur auf die Zähne des Zahnriemens, sondern auch auf den mindestens einen Kraftmitnehmer übertragen, der in entsprechenden Kraftmitnehmeraussparungen der Zahnscheibe ist. Hierdurch können dann ggfs. sogar größere Kräfte übertragen werden.The drive device therefore has at least one toothed disc with tooth recesses for entrainment of teeth of the toothed belt and Kraftmitnehmeraussparungen for entrainment of the at least one Kraftmitnehmers, which usually does not drive, but only deflects the timing belt. Within the scope of the invention, however, this toothed disk can also be designed as a driving toothed disk. Then, the driving force is transmitted from the toothed pulley to the toothed belt or the driven element not only on the teeth of the toothed belt, but also on the at least one Kraftmitnehmer, which is in corresponding Kraftmitnehmeraussparungen the toothed wheel. As a result, if necessary. Even larger forces can be transmitted.
Insbesondere können mehrere Kraftmitnehmer gemeinsam das anzutreibende Element bewegen. Befinden sich mehrere Kraftmitnehmer gleichzeitig in Kraftaufnehmeraussparungen der Zahnscheibe, wird der Zahnriemen erheblich entlastet, da sich die Kräfte auf die mehreren Kraftmitnehmer verteilen. Dies ist auch deswegen vorteilhaft, weil durch die Führung der Kraftaufnehmer über die Zahnscheibe ein Richtungswechsel aus der zuvor ausschließlich vorherrschenden Richtungskomponente in x-Richtung erfolgen kann. Richtungswechsel sind oft mit dynamischen Belastungsspitzen verbunden, die durch die unmittelbare Verbindung der Kraftaufnehmer mit der Zahnscheibe aufgenommen und kompensiert werden können. Die Umlenkung der Richtung über die Zahnscheibe kann dabei entsprechend üblichen Zahnriemenantrieben um wenige Grad bis hin zu einem vollständigen Richtungswechsel von 180° erfolgen.In particular, several Kraftmitnehmer can move the driven element together. If several power take-offs are simultaneously located in load cell recesses of the toothed pulley, the toothed belt is considerably relieved, since the forces are distributed among the several power take-offs. This is also advantageous because by the leadership of the force transducer on the toothed wheel a change of direction from the previously exclusively prevailing directional component in the x-direction can be done. Change of direction is often associated with dynamic load peaks, which can be absorbed and compensated by the direct connection of the force transducer with the toothed wheel. The deflection of the direction of the toothed wheel can be done in accordance with conventional timing belt drives by a few degrees up to a complete change of direction of 180 °.
In einer besonders vorteilhaften Ausführungsvariante ist der Kraftaufnehmer ausschließlich durch Klemmung an dem Zahnriemen befestigt. Die Klemmverbindung hat den wesentlichen Vorteil, dass die Struktur des Zahnriemens durch die Befestigung nicht verändert wird. Insbesondere bleiben die für die Zugfestigkeit wesentlichen Seile oder Drähte im Inneren des Zahnriemens intakt.In a particularly advantageous embodiment variant, the force transducer is fastened exclusively by clamping on the toothed belt. The clamping connection has the significant advantage that the structure of the toothed belt is not changed by the attachment. In particular, the ropes or wires which are essential for the tensile strength remain intact inside the toothed belt.
Um eine Klemmverbindung gewährleisten zu können, ist der Kraftmitnehmer vorzugsweise in eine Oberseite und eine Unterseite unterteilt, zwischen denen im befestigten Zustand der Zahnriemen angeordnet ist. Die Unterseite ist dabei auf der verzahnten Seite des Zahnriemens angeordnet und kann zur verbesserten Kraftübertragung in x-Richtung eine dem Zahnriemen zugewandte Innenseite aufweisen, die mit den Zähnen des Zahnriemens korrespondiert. Beispielsweise kann das Unterteil eine gezackte Kontur aufweisen, in der Zähne des Zahnriemens zur Anlage kommen. Dies führt zu einer kraftformschlüssigen Verbindung des Kraftmitnehmers mit dem Zahnriemen.In order to ensure a clamping connection, the power cam is preferably divided into an upper side and a lower side, between which the toothed belt is arranged in the attached state. The underside is arranged on the toothed side of the toothed belt and may have an inner side facing the toothed belt for improved force transmission in the x-direction, which corresponds to the teeth of the toothed belt. For example, the lower part may have a serrated contour in which teeth of the toothed belt come to rest. This leads to a form-locking connection of Kraftmitnehmers with the timing belt.
Die Verbindung des Oberteils und des Unterteils kann durch beliebige geeignete Mittel erfolgen. Es hat sich als vorteilhaft erwiesen, wenn der Kraftmitnehmer eine Länge aufweist, die eine Breite des Zahnriemens (quer zur Längserstreckung) übersteigt. Die Länge des Kraftmitnehmers ist in am Zahnriemen befestigten Zustand quer zur Laufrichtung bzw. Längserstreckung des Zahnriemens angeordnet. Verbindungselemente, beispielsweise Schrauben verbinden das Oberteil mit dem Unterteil, wobei die Schrauben seitlich des Zahnriemens angeordnet sind und diesen nicht durchdringen.The connection of the top and the bottom can be made by any suitable means. It has proved to be advantageous if the power cam has a length which exceeds a width of the toothed belt (transverse to the longitudinal extent). The length of the Kraftmitnehmers is arranged in a state attached to the toothed belt transversely to the direction or longitudinal extension of the toothed belt. Connecting elements, such as screws connect the upper part with the lower part, wherein the screws are arranged laterally of the toothed belt and not penetrate.
Der Kraftmitnehmer bildet auch ein Verbindungselement aus, das mit dem anzutreibenden Element verbindbar ist. Vorzugsweise ist ein Überstand vorgesehen, der mit dem antreibenden Element oder einem zusätzlichen Verbindungszwischenelement verbindbar ist. Ein solcher Überstand kann beispielsweise durch einen zylindrischen Achsstummel gebildet sein. Ein Achsstummel ist deshalb besonders geeignet, weil dieser eine schwenk- oder drehbare Verbindung mit dem anzutreibenden Element oder dem dazwischen angeordneten Verbindungszwischenelement erlaubt. Die Schwenk- oder Drehbarkeit zwischen dem Verbindungselement und dem anzutreibenden Element ist notwendig, um das anzutreibende Element entlang des Umfangs der Zahnscheibe führen zu können, wenn diese den Kraftmitnehmer umlenkt. Die Schwenk- oder Drehbarkeit muss aber nicht zwangsläufig durch den Kraftmitnehmer bzw. das Verbindungselement selbst gewährleistet sein, möglich ist auch eine starre Verbindung an dieser Stelle, wenn die Schwenk- oder Drehbarkeit an anderer Stelle zwischen dem Kraftmitnehmer und dem anzutreibenden Element realisiert wird.The power cam also forms a connecting element, which is connectable to the driven element. Preferably, a projection is provided, which is connectable to the driving element or an additional intermediate connecting element. Such a supernatant may be formed for example by a cylindrical stub axle. A stub axle is particularly suitable because it allows a pivotal or rotatable connection with the element to be driven or the interposed intermediate connecting element. The pivoting or rotation between the connecting element and the element to be driven is necessary in order to be able to guide the driven element along the circumference of the toothed disk when it deflects the power take-off. The swivel or rotation must but not necessarily be ensured by the power cam or the connecting element itself, is also possible a rigid connection at this point, if the swivel or rotation is realized elsewhere between the power driver and the element to be driven.
In einer besonders einfachen bevorzugten Ausführungsvariante ist der Kraftmitnehmer als im Wesentlichen zylindrisches Element ausgebildet, wobei ein seitlicher Überstand über die Breite des Zahnriemens, also ein endseitiger Achsstummel als Verbindungselement dient. Dabei kann der Kraftmitnehmer nur ein einziges Verbindungselement an einer Seite des Zahnriemens oder auch zwei Verbindungselemente beidseitig des Zahnriemens aufweisen.In a particularly simple preferred embodiment of the power cam is designed as a substantially cylindrical element, wherein a lateral projection over the width of the toothed belt, so an end-side stub axle serves as a connecting element. In this case, the power cam may have only a single connecting element on one side of the toothed belt or two connecting elements on both sides of the toothed belt.
Erfindungsgemäß kann die Kraftübertragung auf das anzutreibende Element dadurch weiter verbessert werden, dass mehrere Kraftmitnehmer nebeneinander am Zahnriemen angeordnet sind, die mit einem einzigen anzutreibenden Element verbunden sind. Eine zusätzliche Verbindungsplatte verbindet dabei die mindestens zwei Kraftmitnehmer derart, dass Zugkräfte von einem Kraftmitnehmer auf den benachbarten Kraftmitnehmer über die Verbindungsplatte übertragen werden können. Die Verbindungsplatte muss zu diesem Zweck schwenk- oder drehbar an einem der beiden Kraftnehmer befestigt sein und weist vorzugsweise ein gekrümmtes Langloch auf, in das sich ein Kraftübertragungsabschnitt des benachbarten Kraftmitnehmers hinein erstreckt. Der Kraftübertragungsabschnitt kann durch das Verbindungselement gebildet sein, also beispielsweise durch einen Achsstummel, der sich durch das gekrümmte Langloch hindurch erstreckt. Das gekrümmte Langloch ist deshalb notwendig, weil ansonsten eine Umlenkung des Zahnriemens über die Zahnscheibe nicht möglich wäre.According to the invention, the power transmission to the driven element can be further improved by arranging a plurality of force drivers side by side on the toothed belt, which are connected to a single element to be driven. An additional connecting plate connects the at least two Kraftmitnehmer such that tensile forces can be transmitted from a Kraftmitnehmer on the adjacent Kraftmitnehmer via the connecting plate. The connecting plate must be pivotally or rotatably attached to one of the two power users for this purpose and preferably has a curved slot into which a power transmission section of the adjacent Kraftmitnehmers extends. The power transmission section may be formed by the connecting element, that is, for example, by a stub axle, which extends through the curved slot. The curved slot is necessary because otherwise a deflection of the belt over the toothed pulley would not be possible.
Um die Kraftübertragung auf das anzutreibende Element weiter zu verbessern, kann vorzugsweise eine ungerade Anzahl an Kraftmitnehmern vorgesehen sein, die über die Verbindungsplatte miteinander verbunden sind. Die Verbindungsplatte ist schwenk- oder drehbar am mittleren Kraftmitnehmer befestigt, wobei sich Kraftübertragungsabschnitte der benachbarten Kraftmitnehmer in entsprechende gekrümmte Langlöcher erstrecken. Lediglich der mittlere Kraftmitnehmer ist dabei über sein Verbindungselement mit dem anzutreibenden Element verbunden, so dass sich auftretende Kräfte über die Verbindungsplatte auf sämtliche verbundenen Kraftmitnehmer verteilen. Es haben sich beispielsweise Gruppierungen von drei oder fünf Kraftmitnehmern, die über eine Verbindungsplatte miteinander verbunden sind, als besonders geeignet erwiesen. Vorteilhafterweise erhöht sich die Spannung innerhalb des Zahnriemens durch die Verbindung der Kraftmitnehmer untereinander bei Kontakt mit der Zahnscheibe nicht.In order to further improve the power transmission to the element to be driven, an odd number of Kraftmitnehmern may be provided, which are interconnected via the connecting plate. The connecting plate is pivotally or rotatably mounted on the middle Kraftmitnehmer, wherein force transmission sections of the adjacent Kraftmitnehmer extend into corresponding curved slots. Only the middle power cam is connected via its connecting element with the element to be driven, so that occurring forces are distributed over the connecting plate on all connected Kraftmitnehmer. For example, there are groupings of three or five Kraftmitnehmern, which are interconnected via a connecting plate, proved to be particularly suitable. Advantageously, the tension within the toothed belt does not increase as a result of the connection of the force drivers with one another when in contact with the toothed disk.
In einer besonders vorteilhaften Ausführungsvariante weist die Führungsbahn einen bogenförmigen Streckenabschnitt auf, so dass der Kraftmitnehmer derart um die Zahnscheibe bewegt wird, dass sich eine Übertotpunktstellung ergibt. Somit lässt sich eine geschlossene Position des angetriebenen Elements, beispielsweise einer Tür, erreichen, die nicht ohne ein Zurückbewegen des Zahnriemens in die entgegengesetzte Richtung gelöst werden kann. Die Tür ist somit beispielsweise für Fahrgäste sicher verriegelt.In a particularly advantageous embodiment variant, the guide track has an arcuate track section, so that the power cam is moved around the toothed disc in such a way that an over-center position results. Thus, it is possible to achieve a closed position of the driven element, for example a door, which can not be released in the opposite direction without moving the toothed belt backwards. The door is thus securely locked for passengers, for example.
Um die Bewegung einer Schwenkschiebetür mit abschließender Verriegelung auszuführen, weist die Führungsbahn einen ersten geraden Streckenabschnitt, einen zweiten geraden Streckenabschnitt und einen bogenförmigen endseitigen Streckenabschnitt auf, wobei die beiden geraden Streckenabschnitte winklig zueinander angeordnet sind. Somit kann die Tür aus dem Türportal heraus und anschließend parallel zur Fahrzeugaußenwand verschoben werden. Befindet sich die Tür im Türportal, ist sie in der Endlage durch die Übertotpunktverriegelung sicher verriegelt.In order to carry out the movement of a sliding sliding door with final locking, the guide track has a first straight track section, a second straight track section and an arcuate end track section, wherein the two straight track sections are arranged at an angle to each other. Thus, the door can be moved out of the door portal and then parallel to the vehicle outer wall. If the door is located in the door portal, it is securely locked in the end position by the over-center interlock.
Vorzugsweise ist ein angetriebenes Ritzel an einem freien Ende des ersten geraden Streckenabschnitt, eine erste Zahnscheibe im Bereich des Übergangs vom ersten geraden Streckenabschnitt zum zweiten geraden Streckenabschnitt und eine zweite Zahnscheibe im Bereich des bogenförmigen endseitigen Streckenabschnitt angeordnet.Preferably, a driven pinion is arranged at a free end of the first straight section, a first toothed disc in the region of the transition from the first straight section to the second straight section and a second toothed disc in the region of the arcuate end-side section.
