Definitions
- the present invention relates to a locking device for vehicle doors, in particular for buses and rail vehicles, with a rotatably mounted rotary latch with a recess for locking a catch bolt.
- vehicle door is understood in the context of the invention both individual door leaves of two-leaf doors, in particular sliding doors and swing doors, as well as single doors. Sliding sliding doors are commonly used in rail vehicles or buses, although the invention is not intended to be limited to such vehicles. It is known to use sliding doors, e.g. also with airplanes or water vehicles.
- rotary latch locks On single or double-leaf rail vehicle doors locking the door leaf is often used on rotary latch locks to meet high loads of the door system.
- These rotary latch locks have a rotatably mounted rotary latch, which usually cooperates with a catch bolt or a similar element.
- the catch bolt is usually arranged on the door, while the catch is attached to the door portal.
- the catch bolt is guided when closing the door in a recess of the catch, the catch is rotated and surrounds the catch bolt such that it is in the Y direction, ie in the respective direction which extends transversely to the door opening locked. To open the door, the catch must be turned back so that the rotary latch recess can release the door in the Y direction again.
- Rotary latch locks can be operated electrically, pneumatically, hydraulically or via linkages or cables.
- Pivoting sliding doors are known for example for rail vehicles in different variants.
- Allen is common that they move from a closed position by a transverse or pivoting movement in an open Position and then moved parallel to the vehicle outer wall in a door opening releasing position. In the closed position, the door must be pulled firmly against the door seal and locked. The problem is that the resistance of the door seal must be overcome. The vehicle doors are therefore closed quickly or with high momentum, which generates an unpleasant loud noise and leads to increased wear of all components involved.
- the object of the present invention is to provide a locking device that is as simple as possible, ensures secure locking and its manufacture and installation is inexpensive and easy.
- the locking and unlocking should be possible with the simplest possible means and using less robust components quietly and with little wear.
- the object is achieved by a locking and unlocking system for vehicle doors with the features of claim 1.
- the invention is based on the principle that the entire lock, which is usually arranged on the door portal, is moved in the closing direction and thereby entrains the catch bolt and thus the door. It is therefore not only the locking bolt on the locking pawl moves, which is structurally complex and difficult due to the balance of power and leverage.
- catch bolt and the locking pawl are in a final engagement with each other before reaching the closed end position of the door.
- the door is thus already locked before the entire lock moves and the door or the door element is pulled into the closed position, overcoming the force applied by the door seal counterforce.
- the locking of the catch bolt using the locking pawl according to the invention takes place before the movement of the lock in the end position.
- a temporal overlap of the two movements or operations is possible.
- the movement of the lock already begin before the locking pawl is close to reaching its final position.
- the door After a release of the catch bolt by a corresponding unlocking the locking pawl, the door can be opened as usual again, the lock is brought over an opposite movement back to the original position.
- the lock performs a pivoting movement. This is favorable because, inter alia, leverage between the position of the drive and the position of the engaging catch bolt can be exploited.
- the lock is mounted movably mounted and pivotally via a pivot bearing, which is fixed to the door portal.
- the drive of the pivoting movement takes place via an electric motor.
- the electric motor acts on an actuator, which presses the lock in the desired movement.
- the actuator is designed as an eccentric element, which is expressed on stationary elements.
- the actuator may for example be designed as eccentric pivot pin.
- a transmission is provided, which may be designed for example as a helical gear or planetary gear. All occurring forces are transmitted via the specially designed geometry of the eccentric element to the adjacent contact surfaces.
- the lock which includes the catch, mounted on a base plate.
- the base plate is movably mounted on the door portal.
- a slot in the one Bearing pin projects, whereby a guide of the pivotable base plate takes place.
- the base plate is preferably made substantially rectangular, wherein the pivot bearing is arranged in the region of one of the two narrower sides.
- Essential in this embodiment is further that the motor and the gear that put the base plate in motion, are firmly connected to the door portal and are not even moved or pivoted.
- the displacement of the base plate in the slot is achieved by the eccentric pintle is pressed during rotation of the transmission against contact surfaces which are arranged on the base plate.
- the eccentric pintle protrudes with its free end formed on the lock, opposite contact surfaces and contacted during its rotational movement, either the first contact surface or second contact surface and thus pushes them in the desired direction.
- the catch bolt When closing the door, the catch bolt first moves into the lock or the open catch and is fixed in this position via the locking pawl. Already in this state, if desired, the door can be signaled as locked and the vehicle can already start. After locking or fixing the catch bolt, the motor is driven, which rotates the eccentric pintle via the gear, whereby the base plate and thus the entire lock with the catch bolt against the door seal in an end position in which the door is fully closed pulled.
- the drive of the locking pawl can be done according to the invention via a dedicated second motor or actuator, but it is also possible to use the already existing motor for driving the eccentric pivot pin for driving the locking pawl.
- the locking pawl can be moved for example via Bowden cable or a similar mechanical coupling.
- a drive element is provided which rotates with the eccentric pivot pin.
- the drive element may for example be designed as a lever to which the Bowden cable is fastened for the locking pawl.
- the lever is designed and aligned such that upon rotation of the eccentric First turn the Bowden cable is moved before the eccentric pivot pin abuts on one of the contact surfaces. This is necessary so that the catch bolt can first be picked up and locked before the base plate is moved with the lock.
- the eccentric pintle, the drive element and the contact surfaces must be matched accordingly.
- the engine and the transmission are not fixed to the door portal, but move along with the movement of the lock. It is also an eccentric pivot pin provided which presses against contact surfaces, but these are firmly connected to the door portal.
- the second embodiment variant can be realized, for example, by the fact that the base plate provided in the first embodiment represents, as it were, a component of the lock and is connected to a carrier plate fixedly arranged on the door portal.
- the base plate is pivotable relative to the support plate, for example, also via a pivot bearing and a bearing pin.
- the motor and the gear are fixed in this embodiment also fixed to the base plate and are thus moved together with the base plate.
- the aforementioned contact surfaces are in this embodiment with the support plate, and thus connected to the door portal and arranged such that the eccentric pivot pin contacts them and the base plate pivots with the lock accordingly.
- the catch bolt initially moves into the lock or into the catch and is fixed there via the locking pawl. Subsequently, the base plate is driven and pivoted about the rotating eccentric pivot pin. The door is moved against the door seal in the final closed end position. Already after retraction of the catch bolt in the catch, if desired, the vehicle can be signaled as locked and already start.
- the locking pawl can be moved via a second motor, but it can also used the already existing motor for driving the eccentric pivot pin become.
- an additional eccentric locking bolt is provided, which protrudes from the free end of the eccentric pivot pin and contacts a lever upon rotation of the eccentric pivot pin, which in turn opens the rotary latch. The closing of the catch takes place via the momentum of the catch bolt or the door, which, however, must be substantially lower, since no sealing force or port tolerances must be overcome.

Description
Die vorliegende Erfindung betrifft eine Verriegelungseinrichtung für Fahrzeugtüren, insbesondere für Busse und Schienenfahrzeuge, mit einer drehbar gelagerten Drehfalle mit einer Ausnehmung zur Arretierung eines Fangbolzens.The present invention relates to a locking device for vehicle doors, in particular for buses and rail vehicles, with a rotatably mounted rotary latch with a recess for locking a catch bolt.
Unter dem Begriff Fahrzeugtür werden im Sinne der Erfindung sowohl einzelne Türflügel von zweiflügligen Türen, insbesondere Schwenkschiebetüren und Außenschwingtüren, als auch Einzeltüren verstanden. Schwenkschiebetüren werden üblicherweise bei schienengebundenen Fahrzeugen oder Bussen eingesetzt, obwohl die Erfindung nicht auf derartige Fahrzeuge beschränkt sein soll. Bekannt ist der Einsatz von Schwenkschiebetüren z.B. auch bei Flugzeugen oder Wasserfahrzeugen.The term vehicle door is understood in the context of the invention both individual door leaves of two-leaf doors, in particular sliding doors and swing doors, as well as single doors. Sliding sliding doors are commonly used in rail vehicles or buses, although the invention is not intended to be limited to such vehicles. It is known to use sliding doors, e.g. also with airplanes or water vehicles.
An ein- oder zweiflügeligen Schienenfahrzeugtüren wird häufig eine Verriegelung der Türflügel über Drehfallenverriegelungen angewendet, um hohen Belastungen des Türsystems gerecht zu werden. Diese Drehfallenverriegelungen weisen eine drehbar gelagerte Drehfalle auf, die in der Regel mit einem Fangbolzen oder einem ähnlichen Element zusammenwirkt. Der Fangbolzen ist üblicherweise an der Tür angeordnet, während die Drehfalle am Türportal befestigt ist.On single or double-leaf rail vehicle doors locking the door leaf is often used on rotary latch locks to meet high loads of the door system. These rotary latch locks have a rotatably mounted rotary latch, which usually cooperates with a catch bolt or a similar element. The catch bolt is usually arranged on the door, while the catch is attached to the door portal.
Der Fangbolzen wird beim Schließen der Tür in eine Ausnehmung der Drehfalle hineingeführt, die Drehfalle wird gedreht und umschließt den Fangbolzen derart, dass dieser in Y-Richtung, also in der jeweiligen Richtung, die quer zur Türöffnung verläuft, arretiert ist. Um die Tür öffnen zu können, muss die Drehfalle wieder zurückgedreht werden, damit die Drehfallenausnehmung die Tür in Y-Richtung wieder freigeben kann.The catch bolt is guided when closing the door in a recess of the catch, the catch is rotated and surrounds the catch bolt such that it is in the Y direction, ie in the respective direction which extends transversely to the door opening locked. To open the door, the catch must be turned back so that the rotary latch recess can release the door in the Y direction again.
Drehfallenverriegelungen können dabei elektrisch, pneumatisch, hydraulisch oder über Gestänge oder Seilzüge betätigt werden.Rotary latch locks can be operated electrically, pneumatically, hydraulically or via linkages or cables.
Schwenkschiebetüren sind z.B. für Schienenfahrzeuge in unterschiedlichen Ausführungsvarianten bekannt. Allen ist gemein, dass sie aus einer Schließstellung durch eine Quer- oder Schwenkbewegung in eine öffnungsbereite Stellung und anschließend parallel zur Fahrzeugaußenwand in eine die Türöffnung freigebende Stellung bewegt werden. In der Schließstellung muss dabei die Tür fest an die Türdichtung herangezogen und verriegelt werden. Problematisch ist dabei, dass die der Widerstand der Türdichtung überwunden werden muss. Die Fahrzeugtüren werden deshalb schnell bzw. mit hohem Schwung geschlossen, was ein unangenehmes lautes Geräusch erzeugt und zu erhöhtem Verschleiß aller beteiligten Komponenten führt.Pivoting sliding doors are known for example for rail vehicles in different variants. Allen is common that they move from a closed position by a transverse or pivoting movement in an open Position and then moved parallel to the vehicle outer wall in a door opening releasing position. In the closed position, the door must be pulled firmly against the door seal and locked. The problem is that the resistance of the door seal must be overcome. The vehicle doors are therefore closed quickly or with high momentum, which generates an unpleasant loud noise and leads to increased wear of all components involved.
Die Aufgabe der vorliegenden Erfindung besteht darin, eine Verriegelungseinrichtung zu schaffen, die möglichst einfach aufgebaut ist, eine sichere Arretierung gewährleistet und dessen Herstellung und Montage kostengünstig und einfach ist. Insbesondere soll der Ver- und Entriegelungsvorgang mit möglichst einfachen Mitteln und unter Nutzung weniger, robuster Bauteile leise und mit geringem Verschleiß möglich sein.The object of the present invention is to provide a locking device that is as simple as possible, ensures secure locking and its manufacture and installation is inexpensive and easy. In particular, the locking and unlocking should be possible with the simplest possible means and using less robust components quietly and with little wear.
Erfindungsgemäß wird die Aufgabe durch ein Ver- und Entriegelungssystem für Fahrzeugtüren mit den Merkmalen des Patentanspruchs 1 gelöst.According to the invention the object is achieved by a locking and unlocking system for vehicle doors with the features of claim 1.
Die Erfindung wird im Folgenden anhand der üblichen Konstruktion bei Türen erläutert, nämlich dass das Schloss an einem Türportal und der Fangbolzen an der Tür angeordnet sind. Selbstverständlich ist auch die umgekehrte Anordnung möglich.The invention will be explained below with reference to the usual construction in doors, namely that the lock on a door portal and the catch bolt are arranged on the door. Of course, the reverse arrangement is possible.
Im Gegensatz zu bekannten Verriegelungseinrichtungen basiert die Erfindung auf dem Prinzip, dass das gesamte Schloss, welches üblicherweise am Türportal angeordnet ist, in Schließrichtung bewegt wird und dabei den Fangbolzen und somit die Tür mitnimmt. Es wird also nicht lediglich der Verriegelungsbolzen über die Verriegelungsklinke bewegt, was aufgrund der Kräfteverhältnisse und Hebelwirkungen konstruktiv aufwendiger und schwieriger ist.In contrast to known locking devices, the invention is based on the principle that the entire lock, which is usually arranged on the door portal, is moved in the closing direction and thereby entrains the catch bolt and thus the door. It is therefore not only the locking bolt on the locking pawl moves, which is structurally complex and difficult due to the balance of power and leverage.
Wesentlich ist auch, dass der Fangbolzen und die Verriegelungsklinke bereits vor Erreichen der geschlossenen Endposition der der Tür, miteinander in einem finalen Eingriff stehen. Die Tür ist somit bereits verriegelt, bevor das gesamte Schloss verlagert und die Tür beziehungsweise das Türelement in die geschlossene Position unter Überwindung der durch die Türdichtung aufgebrachten Gegenkraft gezogen wird.It is also essential that the catch bolt and the locking pawl are in a final engagement with each other before reaching the closed end position of the door. The door is thus already locked before the entire lock moves and the door or the door element is pulled into the closed position, overcoming the force applied by the door seal counterforce.
Die Verriegelung des Fangbolzens mithilfe der Verriegelungsklinke erfolgt erfindungsgemäß vor der Bewegung des Schlosses in die Endstellung. Alternativ ist aber auch eine zeitliche Überschneidung der beiden Bewegungen oder Vorgänge möglich. So kann beispielsweise in einer alternativen Ausführungsvariante die Bewegung des Schlosses bereits dann beginnen, bevor sich die Verriegelungsklinke kurz vor Erreichen ihrer endgültigen Position befindet.The locking of the catch bolt using the locking pawl according to the invention takes place before the movement of the lock in the end position. Alternatively, however, a temporal overlap of the two movements or operations is possible. Thus, for example, in an alternative embodiment, the movement of the lock already begin before the locking pawl is close to reaching its final position.
Nach einer Freigabe des Fangbolzens durch eine entsprechende Entriegelung der Verriegelungsklinke kann die Tür wie gewohnt wieder geöffnet werden, wobei das Schloss über eine gegenläufige Bewegung zurück in die Ursprungsposition gebracht wird.After a release of the catch bolt by a corresponding unlocking the locking pawl, the door can be opened as usual again, the lock is brought over an opposite movement back to the original position.
In einer besonders einfachen und vorteilhaften Ausführungsvariante vollführt das Schloss eine Schwenkbewegung. Diese ist günstig, weil hierdurch unter anderem Hebelkräfte zwischen der Position des Antriebs und der Position des in Eingriff bestehenden Fangbolzens ausgenutzt werden können.In a particularly simple and advantageous embodiment, the lock performs a pivoting movement. This is favorable because, inter alia, leverage between the position of the drive and the position of the engaging catch bolt can be exploited.
Es hat sich als besonders günstig erwiesen, wenn das Schloss bewegbar gelagert montiert ist und über einen Drehlager, welches am Türportal fixiert ist, schwenkbar ist. In einer besonders vorteilhaften Ausführungsvariante erfolgt der Antrieb der Schwenkbewegung über einen Elektromotor. Der Elektromotor wirkt auf einen Aktuator, der das Schloss in die gewünschte Bewegung drückt. Es hat sich gezeigt, dass eine besonders robuste und wartungsarme Ausführung dann gegeben ist, wenn der Aktuator als exzentrisches Element ausgeführt ist, welches sich an stationären Elementen abdrückt. Der Aktuator kann beispielsweise als exzentrischer Drehbolzen ausgeführt sein.It has proved to be particularly advantageous when the lock is mounted movably mounted and pivotally via a pivot bearing, which is fixed to the door portal. In a particularly advantageous embodiment, the drive of the pivoting movement takes place via an electric motor. The electric motor acts on an actuator, which presses the lock in the desired movement. It has been found that a particularly robust and low-maintenance design is given when the actuator is designed as an eccentric element, which is expressed on stationary elements. The actuator may for example be designed as eccentric pivot pin.
Zwischen dem Aktuator und dem Motor, vorzugsweise dem Elektromotor, ist ein Getriebe vorgesehen, das beispielsweise als Schraubengetriebe oder Planetengetriebe ausgeführt sein kann. Sämtliche auftretenden Kräfte werden über die speziell ausgeführte Geometrie des exzentrischen Elements an die benachbarten Kontaktflächen übertragen.Between the actuator and the motor, preferably the electric motor, a transmission is provided, which may be designed for example as a helical gear or planetary gear. All occurring forces are transmitted via the specially designed geometry of the eccentric element to the adjacent contact surfaces.
In einer ersten Ausführungsvariante ist das Schloss, welches die Drehfalle beinhaltet, auf einer Grundplatte montiert. Die Grundplatte ist bewegbar am Türportal gelagert. Für eine bessere und dauerhaft exakte Führung kann weiterhin ein Langloch innerhalb der Grundplatte vorgesehen sein, in das ein Lagerbolzen hineinragt, wodurch eine Führung der schwenkbaren Grundplatte erfolgt. Die Grundplatte ist vorzugsweise im Wesentlichen rechteckig ausgeführt, wobei das Drehlager im Bereich einer der beiden schmaleren Seiten angeordnet ist.In a first embodiment, the lock, which includes the catch, mounted on a base plate. The base plate is movably mounted on the door portal. For a better and permanently accurate guidance can still be provided within the base plate, a slot in the one Bearing pin projects, whereby a guide of the pivotable base plate takes place. The base plate is preferably made substantially rectangular, wherein the pivot bearing is arranged in the region of one of the two narrower sides.
Wesentlich bei dieser Ausführungsvariante ist weiterhin, dass der Motor und das Getriebe, die die Grundplatte in Bewegung versetzen, fest mit dem Türportal verbunden sind und selbst nicht bewegt oder verschwenkt werden. Die Verschiebung der Grundplatte im Langloch wird erreicht, indem der exzentrische Drehbolzen beim Drehen des Getriebes gegen Kontaktflächen gedrückt wird, die auf der Grundplatte angeordnet sind. Hierzu ragt der exzentrische Drehbolzen mit seinem freien Ende zwischen am Schloss ausgebildete, einander gegenüberliegende Kontaktflächen und kontaktiert während seiner Drehbewegung entweder die erste Kontaktfläche oder zweite Kontaktfläche und drückt diese somit in die gewünschte Richtung.Essential in this embodiment is further that the motor and the gear that put the base plate in motion, are firmly connected to the door portal and are not even moved or pivoted. The displacement of the base plate in the slot is achieved by the eccentric pintle is pressed during rotation of the transmission against contact surfaces which are arranged on the base plate. For this purpose, the eccentric pintle protrudes with its free end formed on the lock, opposite contact surfaces and contacted during its rotational movement, either the first contact surface or second contact surface and thus pushes them in the desired direction.
Beim Schließen der Tür fährt zuerst der Fangbolzen in das Schloss beziehungsweise die geöffnete Drehfalle und wird in dieser Stellung über die Verriegelungsklinke fixiert. Bereits in diesem Zustand kann, wenn gewünscht, die Tür als verriegelt signalisiert werden und das Fahrzeug kann bereits losfahren. Nach der Verriegelung beziehungsweise Fixierung des Fangbolzens wird der Motor angesteuert, der über das Getriebe den exzentrischen Drehbolzen dreht, wodurch die Grundplatte und damit das gesamte Schloss mit dem Fangbolzen gegen die Türdichtung in eine Endstellung, in der die Tür vollständig geschlossen ist, gezogen.When closing the door, the catch bolt first moves into the lock or the open catch and is fixed in this position via the locking pawl. Already in this state, if desired, the door can be signaled as locked and the vehicle can already start. After locking or fixing the catch bolt, the motor is driven, which rotates the eccentric pintle via the gear, whereby the base plate and thus the entire lock with the catch bolt against the door seal in an end position in which the door is fully closed pulled.
Der Antrieb der Verriegelungsklinke kann dabei erfindungsgemäß über einen dafür vorgesehenen zweiten Motor oder Aktuator erfolgen, es ist aber auch möglich, den ohnehin vorhandenen Motor zum Antrieb des exzentrischen Drehbolzens auch für den Antrieb der Verriegelungsklinke zu nutzen. Die Verriegelungsklinke kann beispielsweise über Bowdenzug oder eine ähnliche mechanische Kopplung bewegt werden. So kann zum Beispiel erfindungsgemäß vorgesehen sein, dass an einem freien Ende des exzentrischen Drehbolzens ein Antriebselement vorgesehen ist, welches sich mit dem exzentrischen Drehbolzen dreht. Das Antriebselement kann beispielsweise als Hebel ausgeführt sein, an dem der Bowdenzug für die Verriegelungsklinke befestigt ist. Der Hebel ist dabei derart ausgeführt und ausgerichtet, dass bei einer Drehung des exzentrischen Drehbolzens zunächst der Bowdenzug bewegt wird, bevor sich der exzentrische Drehbolzen an einer der Kontaktflächen abdrückt. Dies ist notwendig, damit der fangbolzen zunächst aufgenommen und verriegelt werden kann, bevor die Grundplatte mit dem Schloss bewegt wird. Der exzentrische Drehbolzen, das Antriebselement und die Kontaktflächen müssen dementsprechend aufeinander abgestimmt sein.The drive of the locking pawl can be done according to the invention via a dedicated second motor or actuator, but it is also possible to use the already existing motor for driving the eccentric pivot pin for driving the locking pawl. The locking pawl can be moved for example via Bowden cable or a similar mechanical coupling. Thus, for example, be provided according to the invention that at a free end of the eccentric pivot pin, a drive element is provided which rotates with the eccentric pivot pin. The drive element may for example be designed as a lever to which the Bowden cable is fastened for the locking pawl. The lever is designed and aligned such that upon rotation of the eccentric First turn the Bowden cable is moved before the eccentric pivot pin abuts on one of the contact surfaces. This is necessary so that the catch bolt can first be picked up and locked before the base plate is moved with the lock. The eccentric pintle, the drive element and the contact surfaces must be matched accordingly.
In einer zweiten erfindungsgemäßen Ausführungsvariante ist vorgesehen, dass der Motor und das Getriebe nicht am Türportal fixiert sind, sondern sich bei der Bewegung des Schlosses mitbewegen. Es ist ebenfalls ein exzentrischer Drehbolzen vorgesehen, der sich an Kontaktflächen abdrückt, diese sind jedoch fest mit dem Türportal verbunden.In a second variant of the invention, it is provided that the engine and the transmission are not fixed to the door portal, but move along with the movement of the lock. It is also an eccentric pivot pin provided which presses against contact surfaces, but these are firmly connected to the door portal.
Die zweite Ausführungsvariante kann beispielsweise dadurch realisiert werden, dass die bei der ersten Ausführungsvariante vorgesehene Grundplatte sozusagen ein Bauteil des Schlosses darstellt und mit einer fest am Türportal angeordneten Trägerplatte verbunden ist. Die Grundplatte ist gegenüber der Trägerplatte verschwenkbar ausgeführt, beispielsweise ebenfalls über ein Drehlager und einen Lagerbolzen.The second embodiment variant can be realized, for example, by the fact that the base plate provided in the first embodiment represents, as it were, a component of the lock and is connected to a carrier plate fixedly arranged on the door portal. The base plate is pivotable relative to the support plate, for example, also via a pivot bearing and a bearing pin.
Der Motor und das Getriebe sind bei dieser Ausführungsvariante ebenfalls fest auf der Grundplatte fixiert und werden somit zusammen mit der Grundplatte bewegt. Die bereits genannten Kontaktflächen sind bei dieser Ausführungsvariante mit der Trägerplatte, und somit mit dem Türportal verbunden und derart angeordnet, dass der exzentrische Drehbolzen diese kontaktiert und die Grundplatte mit dem Schloss entsprechend schwenkt.The motor and the gear are fixed in this embodiment also fixed to the base plate and are thus moved together with the base plate. The aforementioned contact surfaces are in this embodiment with the support plate, and thus connected to the door portal and arranged such that the eccentric pivot pin contacts them and the base plate pivots with the lock accordingly.
Der Fangbolzen fährt zunächst in das Schloss beziehungsweise in die Drehfalle ein und wird dort über die Verriegelungsklinke fixiert. Anschließend wird die Grundplatte über den sich drehenden exzentrischen Drehbolzen angetrieben und verschwenkt. Die Tür wird gegen die Türdichtung in die endgültig geschlossene Endstellung verschoben. Bereits nach Einfahren des Fangbolzens in die Drehfalle kann, wenn gewünscht, das Fahrzeug als verriegelt signalisiert werden und bereits losfahren.The catch bolt initially moves into the lock or into the catch and is fixed there via the locking pawl. Subsequently, the base plate is driven and pivoted about the rotating eccentric pivot pin. The door is moved against the door seal in the final closed end position. Already after retraction of the catch bolt in the catch, if desired, the vehicle can be signaled as locked and already start.
Auch bei dieser Ausführungsvariante kann die Verriegelungsklinke über einen zweiten Motor bewegt werden, es kann aber auch der ohnehin bereits vorhandene Motor für den Antrieb des exzentrischen Drehbolzens genutzt werden. In einer besonders vorteilhaften Ausführungsvariante ist ein zusätzlicher exzentrischer Verriegelungsbolzen vorgesehen, der vom freien Ende des exzentrischen Drehbolzens absteht und bei Drehung des exzentrischen Drehbolzens einen Hebel kontaktiert, der wiederrum die Drehfalle öffnet. Das Schließen der Drehfalle erfolgt über den Schwung des Fangbolzens bzw. der Tür, der jedoch wesentlich geringer sein muss, da keine Dichtungskraft oder Portaltoleranzen überwunden werden müssen.Also in this embodiment, the locking pawl can be moved via a second motor, but it can also used the already existing motor for driving the eccentric pivot pin become. In a particularly advantageous embodiment, an additional eccentric locking bolt is provided, which protrudes from the free end of the eccentric pivot pin and contacts a lever upon rotation of the eccentric pivot pin, which in turn opens the rotary latch. The closing of the catch takes place via the momentum of the catch bolt or the door, which, however, must be substantially lower, since no sealing force or port tolerances must be overcome.
