Description

Die Erfindung betrifft ein Kraftfahrzeug-Türschloß o. dgl. mit den Merkmalen des Oberbegriffs von Anspruch 1.The invention relates to a motor vehicle door lock o. The like. With the features the preamble of claim 1.

Kraftfahrzeug-Türschlösser o. dgl. mit einem elektromotorischen Öffnungsantrieb sind in vielen Ausführungsformen bekannt. In jüngerer Zeit bekannt geworden sind insbesondere reine Elektroschlösser, das sind Kraftfahrzeug-Türschlösser, die keine mechanischen Betätigungsfunktionen aufweisen oder mechanische Betätigungsfunktionen nur noch für Notfallzwecke aufweist (DE - C - 44 36 617).Motor vehicle door locks o. The like. With an electric motor opening drive are known in many embodiments. More recently known in particular pure electric locks have become, these are motor vehicle door locks, which have no mechanical actuation functions or mechanical actuation functions only for emergency purposes (DE - C - 44 36 617).

Ein Problem bei Kraftfahrzeug-Türschlössern o. dgl. mit Öffnungsantrieb besteht darin, daß die Öffnung auch dann sicher möglich sein muß, wenn auf der Schloßfalle sehr hohe Kräfte in Öffnungsrichtung lasten, die zu einer hohen Haftreibung zwischen Sperrklinke und Schloßfalle in Schließstellung führen. Das bedeutet, daß der elektrische Antriebsmotor des Öffnungsantriebs und das Untersetzungsgetriebe so ausgelegt werden müssen, daß sie auch in diesem ungünstigsten Fall noch sicher eine Öffnung ermöglichen. Das führt zu der Anforderung, daß entweder der elektrische Antriebsmotor des Öffnungsantriebs sehr groß dimensioniert werden muß mit der Folge, daß häufig der Öffnungsantrieb nicht mehr im Gehäuse des Kraftfahrzeug-Türschlosses selbst untergebracht werden kann (siehe auch die DE - C - 44 36 617), und/oder daß das Untersetzungsverhältnis des Untersetzungsgetriebes so groß sein muß, daß das Öffnen durch den Öffnungsantrieb außerordentlich lange dauert. Betätigungszeiten von mehreren hundert Millisekunden sind insoweit keine Seltenheit. Gewohnt an die Öffnungszeiten mechanisch betätigter Kraftfahrzeug-Türschlösser o. dgl. werden diese Betätigungszeiten vom Benutzer als störend lang empfunden.A problem with motor vehicle door locks o. The like. With opening drive in that the opening must be safe even if on the Lock trap load very high forces in the opening direction, leading to a high Stiction between the pawl and lock latch in the closed position. This means that the electric drive motor of the opening drive and the reduction gear must be designed so that they also in this Worst case still safe to allow an opening. That leads to the requirement that either the electric drive motor of the opening drive must be very large with the result that often the Opening drive no longer in the housing of the motor vehicle door lock itself can be accommodated (see also DE - C - 44 36 617), and / or that the reduction ratio of the reduction gear so must be large, that the opening by the opening drive extraordinarily takes long. Operating times of several hundred milliseconds are so far not uncommon. Used to the opening hours mechanically operated Motor vehicle door locks o. The like. These operating times felt by the user as disturbing long.

Der Erfindung liegt somit das Problem zugrunde, ein Kraftfahrzeug-Türschloß o. dgl. mit einem motorischen Öffnungsantrieb anzugeben, das ein sicheres Ausheben der Sperrklinke aus der entsprechenden Rast der Schloßfalle auch bei erhöhter Kraft am Schließkeil mit möglichst geringer Öffnungsdauer gewährleistet.The invention is therefore based on the problem of a motor vehicle door lock o. The like. With a motorized opening drive indicate that a safe Lifting the pawl from the corresponding latch the latch also guaranteed with increased force on the striker with the least possible opening time.

Die zuvor aufgezeigte Aufgabe ist bei einem Kraftfahrzeug-Türschloß o. dgl. mit den Merkmalen des Oberbegriffs von Anspruch 1 durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst. Erfindungsgemäß wird eine Aushebefeder eingesetzt, um das für die Öffnung des Kraftfahrzeug-Türschlosses o. dgl., also das Ausheben der Sperrklinke erforderliche Drehmoment zu erhöhen. Das für das Ausheben der Sperrklinke zur Verfügung stehende Drehmoment setzt sich erfindungsgemäß aus dem Drehmoment des Antriebsmotors und dem Drehmoment der Aushebefeder zusammen. Auch bei erhöhten Kräften am Schließkeil bzw. an der Schloßfalle ist eine sichere und schnelle Öffnung gewährleistet. Demgegenüber ist es lediglich erforderlich, daß der Antriebsmotor des Öffnungsantriebs auch bei Rücklauf von der Öffnungsstellung in die Schließstellung belastet wird, nämlich durch das Spannen der Aushebefeder.The object indicated above is in a motor vehicle door lock o. The like. with the features of the preamble of claim 1 by the features of the characterizing part of claim 1. According to the invention a Aushebefeder used to that for the opening of the motor vehicle door lock o. The like., So the lifting of the pawl required torque to increase. The available for the lifting of the pawl Torque is inventively from the torque of Drive motor and the torque of the lift spring together. Also with increased forces on the striker or on the latch is a safe and ensures fast opening. In contrast, it is only necessary that the drive motor of the opening drive even when returning from the Opening position is loaded in the closed position, namely by the Tensioning the lifting spring.

Allgemein darf darauf hingewiesen werden, daß sich die Lehre der Erfindung auf Kraftfahrzeug-Türschlösser o. dgl. bezieht, insbesondere also auf Seitentürschlösser, aber auch auf Hecktürschlösser, Heckklappenschlösser und Haubenschlösser. Ferner darf festgehalten werden, daß es sich beim Antriebsmotor des motorischen Öffnungsantriebs vorzugsweise um einen elektrischen Antriebsmotor handeln wird, daß aber grundsätzlich auch andere Antriebsmotoren, beispielsweise Pneumatikantriebe oder Hydromotoren eingesetzt sein können.In general, it should be noted that the teaching of the invention refers to motor vehicle door locks o. The like., Especially on side door locks, but also on rear door locks, tailgate locks and Hood latches. It should also be noted that it is the drive motor the motorized opening drive preferably by an electric Actuator will act, but in principle also other Drive motors, such as pneumatic actuators or hydraulic motors used could be.

Die Lehre der Erfindung hat ihre besondere Bedeutung in Verbindung mit einem Kraftfahrzeug-Türschließsystem, das schlüssellos arbeitet, also mit einer automatischen Personenerkennung etc. Hier ist insbesondere eine schnelle Öffnung des Kraftfahrzeug-Türschlosses erforderlich, die der natürlichen, bei mechanischen Kraftfahrzeug-Türschlössern gewohnten Handhabung entspricht. Diesen Anforderungen entspricht die erfindungsgemäße Lösung in besonderem Maße.The teachings of the invention have their particular significance in connection with a motor vehicle door locking system that operates without a key, ie with a automatic person recognition etc. Here is in particular a fast one Opening of the motor vehicle door lock required, the natural, at mechanical motor vehicle door locks usual handling corresponds. These requirements correspond to the solution according to the invention in special size.

in Fig. 1 corresponding representation of the motor vehicle door lock o. The like. With the closing elements in the open position.

Das in Fig. 1 dargestellte Kraftfahrzeug-Türschloß o. dgl., dargestellt im Ausführungsbeispiel eines Seitentürschlosses, weist zunächst ein Gehäuse 1 mit einem Einlaufschlitz 2 für einen hier lediglich schematisch angedeuteten Schließkeil 3, hier ausgeführt lediglich als zapfenartiger Schließbolzen, auf. Der Stand der Technik gibt eine Vielzahl alternativer Ausführungsformen solcher Schließkeile 3 an.The illustrated in Fig. 1 motor vehicle door lock o. The like., Shown in the exemplary embodiment a side door lock, initially has a housing 1 with an inlet slot 2 for a here only schematically indicated Locking wedge 3, here executed only as a pin-like locking pin, on. The prior art provides a variety of alternative embodiments of such Locking wedges 3 on.

Fig. 1 zeigt die Schließstellung des Kraftfahrzeug-Türschlosses mit der Schloßfalle 4, hier in Form einer Gabel-Drehfalle, die in der dargestellten Schließstellung (Hauptrast 4a, hier auch Vorrast 4b) von einer Sperrklinke 5, hier einer auf Druck beanspruchten Sperrklinke 5, gehalten wird. Alternativ sind auf Zug beanspruchte Sperrklinken 5 oder auch besondere, ringartige Sperrklinken bekannt, wozu auf den Stand der Technik verwiesen werden darf.Fig. 1 shows the closed position of the motor vehicle door lock with the Lock catch 4, here in the form of a fork-catch, which in the illustrated Closed position (main catch 4a, here also Vorrast 4b) of a pawl 5, Here is a claimed on pressure pawl 5, is held. alternative are claimed on train pawls 5 or special, ring-like Pawls known, for which reference is made to the prior art may.

Vorgesehen ist ein motorischer Öffnungsantrieb 6. In dargestellten und bevorzugten Ausführungsbeispiel handelt es sich um einen elektromotorischen Öffnungsantrieb 6, wobei auf die Alternativen zu einem elektromotorischen Öffnungsantrieb 6 bereits oben hingewiesen worden ist. Der Öffnungsantrieb 6 weist hier einen elektrischen Antriebsmotor 7 auf, an den sich ein Untersetzungsgetriebe 8 anschließt, das abtriebsseitig an der Sperrklinke 5 oder, wie hier, an einem die Sperrklinke 5 bewegenden Sperrklinkenhebel 9 o. dgl. angreift. Der Sperrklinkenhebel 9 ist mit der Sperrklinke 5 im dargestellten Ausführungsbeispiel über eine in einer Richtung wirkende Freilaufkupplung verbunden, so daß die Sperrklinke 5 bei geöffneter Schloßfalle 4 von der Schloßfalle 4 selbst in Aushebestellung gehalten werden kann, obgleich der Sperrklinkenhebel 9 bereits die Einfallstellung für die Sperrklinke 5 wieder erreicht hat (die in Fig. 1 dargestellte Stellung). Die Sperrklinke 5 ist dabei, wie an sich aus dem Stand der Technik für solche Fälle bekannt, mittels einer Schenkelfeder 10 in Einfallsrichtung federbelastet.Provided is a motorized opening drive 6. In illustrated and preferred Embodiment is an electromotive Opening drive 6, taking on the alternatives to an electromotive Opening drive 6 has already been pointed out above. The opening drive 6 here has an electric drive motor 7, to which a reduction gear 8 connects, the output side of the pawl 5 or, as Here, on a pawl 5 moving pawl lever 9 o. The like. Attacks. The pawl lever 9 is connected to the pawl 5 in the illustrated embodiment via a unidirectional one-way clutch connected, so that the pawl 5 in the open latch 4 of the Lock catch 4 can be held even in Aushebestellung, although the Pawl lever 9 already the incidence position for the pawl 5 again has reached (the position shown in Fig. 1). The pawl 5 is there, As known from the prior art for such cases, by means of a Leg spring 10 spring-loaded in the direction of incidence.

Bei entsprechender Ansteuerung des elektrischen Antriebsmotors 7 wird die Sperrklinke 5 aus der in Fig. 1 dargestellten Schließstellung herausbewegt und aus der entsprechenden Rastung an der Schloßfalle 4, hier der Hauptrast 4a, ausgehoben, so daß die Schloßfalle 4 freigegeben wird (das ist dann die in Fig. 2 dargestellte Öffnungsstellung).With appropriate control of the electric drive motor 7 is the Pawl 5 moved out of the closed position shown in Fig. 1 and from the corresponding detent on the latch 4, here the main catch 4a, excavated, so that the lock latch 4 is released (this is the in Fig. 2 illustrated opening position).

Wesentlich für die Funktion und Problemlösung bei der Lehre der Erfindung ist nun, daß dem Untersetzungsgetriebe 8 (oder auch dem Sperrklinkenhebel 9) eine in Ausheberichtung der Sperrklinke 5 wirkende Aushebefeder 11 zugeordnet ist. Die Aushebefeder 11 wird bei Rücklauf des Öffnungsantriebs 6 von der Öffnungsstellung in die Schließstellung gespannt und unterstützt bei Vorlauf des Öffnungsantriebs 6 von der Schließstellung in die Öffnungsstellung die Vorlaufbewegung und damit die Aushebebewegung der Sperrklinke 5 mit ihrer Federkraft. Im dargestellten Ausführungsbeispiel läßt sich die Bewegung der hier als Schenkelfeder ausgeführten Aushebefeder 11 leicht nachvollziehen. Fig. 1 zeigt die Schließstellung, aus dieser hat sich die Aushebefeder 11, die Aushebebewegung der Sperrklinke 5 unterstützend, in Öffnungsrichtung in die in Fig. 2 dargestellte Stellung bewegt. Die Federkraft der Aushebefeder 11 unterstützt also die vom elektrischen Antriebsmotor 7 aufgebrachte Öffnungskraft, was die Öffnung auch bei erhöhter Kraft am Schließkeil 3 und damit erhöhter Reibung zwischen Sperrklinke 5 und Schloßfalle 4 möglich macht, außerdem die Öffnungszeiten sowohl für diesen Sonderfall als auch bei normaler Belastung erheblich verkürzt. Essential for the function and problem solving in the teaching of the invention is now that the reduction gear 8 (or the pawl lever 9) associated with a lifting direction of the pawl 5 Aushebefeder 11 assigned is. The Aushebefeder 11 is at return of the opening drive. 6 stretched from the open position to the closed position and assists in Forward flow of the opening drive 6 from the closed position to the open position the forward movement and thus the lifting movement of the pawl 5 with their spring force. In the illustrated embodiment, the movement can be here designed as a leg spring Aushebefeder 11 light comprehend. Fig. 1 shows the closed position, from this has the Aushebefeder 11, the lifting movement of the pawl 5 supportive, in the opening direction moved to the position shown in Fig. 2. The spring force the Aushebefeder 11 thus supports that of the electric drive motor. 7 applied opening force, which the opening even with increased force on Locking wedge 3 and thus increased friction between pawl 5 and Lock trap 4 makes possible, in addition, the opening hours both for this Special case as well as under normal load considerably shortened.

Der Vorteil der erfindungsgemäßen Konstruktion liegt nicht nur in den beiden zuvor angesprochenen Aspekten. Hinzu kommt, daß bei entsprechender Gestaltung der Aushebefeder 11 der elektrische Antriebsmotor 7 deutlich kleiner dimensioniert werden kann als im Stand der Technik unter Berücksichtigung der eingangs erläuterten Voraussetzungen erforderlich. Bauraum, Gewicht und Kosten werden eingespart.The advantage of the construction according to the invention lies not only in the two previously mentioned aspects. In addition, that with appropriate Design of the lifting spring 11 of the electric drive motor 7 clearly smaller dimensions can be dimensioned than in the prior art under consideration the conditions explained above required. space, Weight and costs are saved.

Bislang ist noch nichts darüber ausgesagt worden, wie die bei gespannter Aushebefeder 11 resultierende Rückstellkraft der Aushebefeder 11 im Ruhezustand, also in Schließstellung des Kraftfahrzeug-Türschlosses o. dgl. aufgenommen werden kann. Das ergibt sich bei einem selbsthemmend ausgeführten Untersetzungsgetriebe 8 über das Getriebe selbst. Bei einem nicht selbsthemmend ausgeführten Untersetzungsgetriebe 8, ein solches ist auch im vorliegenden bevorzugten Ausführungsbeispiel vorgesehen, müssen hier zusätzliche Maßnahmen getroffen werden, die bei einem selbsthemmenden Untersetzungsgetriebe 8 aber ebenfalls getroffen werden können.So far nothing has been said about it, as in the strained Aushebefeder 11 resulting restoring force of the Aushebefeder 11 at rest, So in the closed position of the motor vehicle door lock o. The like. Included can be. This results in a self-locking executed Reduction gear 8 via the gearbox itself. In a non-self-locking executed reduction gear 8, such is also present preferred embodiment provided here additional Measures are taken in a self-locking reduction gear 8 but also can be taken.

Der Aushebefeder 11 ist ein in Schließstellung wirksames und als Anschlag für die Aushebefeder 11 wirkendes, die Rückstellkraft der Aushebefeder 11 aufnehmendes Halteelement 12 zugeordnet. Das im dargestellten Ausführungsbeispiel als einseitig angelenkter Schwenkhebel ausgeführte Halteelement 12, das in Einfallsrichtung mittels einer Schenkelfeder 12a vorgespannt ist, wird unmittelbar nach dem Starten der Vorlaufbewegung des Öffnungsantriebs 6 mittels des Untersetzungsgetriebes 8 ausgehoben und gibt dann die Aushebefeder 11 frei. Zuvor allerdings blockiert das Halteelement 12 die Rückkehrbewegung der Aushebefeder 11, nimmt also deren Federkraft auf und leitet diese in das Gehäuse 1 über die Lagerachse 12b des Halteelements 12 ab. Damit wird das Untersetzungsgetriebe 8 von der Federkraft der Aushebefeder 11 im Ruhezustand, also in der Schließstellung vollständig entlastet. Die Rückstellkraft der Aushebefeder 11 tritt erst dann in Wirkung, wenn sie benötigt wird, nämlich unmittelbar nach Starten des Öffnungsantriebs 6 zum Zwecke des Öffnens der Kraftfahrzeugtür. The lifting spring 11 is a in Closed position effective and acting as a stop for the Aushebefeder 11, the restoring force of the lifting spring 11 receiving retaining element 12th assigned. The articulated in the illustrated embodiment as a one-sided Swivel lever running holding element 12, in the direction of arrival is biased by a leg spring 12a, is immediately after the Starting the advance movement of the opening drive 6 by means of the reduction gear 8 excavated and then releases the Aushebefeder 11. before however, the retaining element 12 blocks the return movement of the lifting spring 11, so absorbs their spring force and passes them into the housing. 1 via the bearing axis 12b of the retaining element 12 from. This will be the reduction gear 8 of the spring force of the Aushebefeder 11 at rest, So completely relieved in the closed position. The restoring force of the lifting spring 11 does not take effect until it is needed, namely immediately after starting the opening drive 6 for the purpose of opening the Motor vehicle door.

Wie erläutert ist diese Ausgestaltung von besonderer Bedeutung bei einem nicht selbsthemmend ausgeführten Untersetzungsgetriebe 8, im übrigen auch vorteilhaft bei einem selbsthemmend ausgeführten Untersetzungsgetriebe 8.As explained, this embodiment is of particular importance in a not self-locking executed reduction gear 8, in the rest also advantageous in a self-locking reduction gear. 8

Nun sollen nachfolgend weitere Details des dargestellten Ausführungsbeispiels näher erläutert werden.Now, below, further details of the illustrated embodiment be explained in more detail.

Zunächst ist hier vorgesehen, daß das Untersetzungsgetriebe 8 ein Getriebezahnrad 13 aufweist, die Aushebefeder 11 als diesem Getriebezahnrad 13 zugeordnete Schenkelfeder ausgeführt ist und das Getriebezahnrad 13 ein Mitnahmeelement 13a für einen Schenkel der Aushebefeder 11 aufweist. Der andere Schenkel der Aushebefeder 11 ist am Gehäuse 1 ortsfest an einem Widerlager 14 gelagert. Die als Schenkelfeder ausgeführte Aushebefeder 11 ist um den Mittelbereich des Getriebezahnrads 13 gewickelt. Das Getriebezahnrad 13 weist ein aufgesetztes Zahnsegment 13b auf, das mit einem entsprechenden Zahnsegment 9a am als Segmenthebel ausgeführten Sperrklinkenhebel 9 kämmt. Die Verlagerung der Zahnsegmente 9a/13b relativ zueinander kann beim Vergleich von Fig. 2 und Fig. 1 gut nachvollziehen.First, it is provided here that the reduction gear 8 is a transmission gear 13, the Aushebefeder 11 as this transmission gear 13 associated Leg spring is executed and the transmission gear 13 is a driving element 13a for a leg of the lifting spring 11 has. The other Leg of the lifting spring 11 is fixed to the housing 1 on an abutment 14 stored. The designed as a leg spring Aushebefeder 11 is to the central portion of the transmission gear 13 wound. The transmission gear 13 has an attached toothed segment 13b, which with a corresponding Tooth segment 9a on the pawl lever 9 designed as a segment lever combs. The displacement of the toothed segments 9a / 13b relative to each other can to understand well when comparing Fig. 2 and Fig. 1.

Das dargestellte und insoweit bevorzugte Ausführungsbeispiel zeigt weiter, daß das Untersetzungsgetriebe 8 mehrstufig ausgeführt ist. Im dargestellten Ausführungsbeispiel weist das Untersetzungsgetriebe 8 ein weiteres Getriebezahnrad 15 auf, das Teil einer ersten Getriebestufe ist, die als Schnekkenradstufe ausgeführt ist. Dazu hat der elektrische Antriebsmotor 7 auf seine Abtriebswelle eine Schnecke 7a, die das Eingangselement des Untersetzungsgetriebes 8 darstellt und mit dem als Schneckenrad dienenden Getriebezahnrad 15 kämmt. Dem mittigen Zahnkranz 15a des Getriebezahnrads 15 ist ein weiteres Zahnsegment 13c am Getriebezahnrad 13 zugeordnet. Dieses kämmt mit dem Zahnkranz 15a des Getriebezahnrads 15 und man erkennt die Verlagerung gegeneinander beim Vergleich von Fig. 2 (Öffnungsstellung) mit Fig. 1 (Schließstellung).The illustrated and so far preferred embodiment further shows that the reduction gear 8 is executed in several stages. In the illustrated Embodiment, the reduction gear 8, a further transmission gear 15 on, which is part of a first gear stage, the Schnekkenradstufe is executed. For this purpose, the electric drive motor 7 on his Output shaft, a worm 7a, which is the input element of the reduction gear 8 and with the gearwheel serving as a worm wheel 15 combs. The central sprocket 15 a of the transmission gear 15th is another toothed segment 13 c assigned to the transmission gear 13. This meshes with the ring gear 15a of the gear wheel 15 and you recognize the Displacement against each other in the comparison of Fig. 2 (open position) with Fig. 1 (closed position).

Weiter ist vorgesehen, daß der Aushebefeder 11 bzw. dem zugeordneten Getriebezahnrad 13 ein Schließanschlag 16 und ein Öffnungsanschlag 17 zugeordnet ist. In Fig. 1, der Schließstellung, ist der eine Schenkel der Schenkelfeder, die die Aushebefeder 11 bildet, von Mitnahmeelement 13a am Getriebezahnrad 13 gegen dem Schließanschlag 16 gedrückt worden. In dieser Stellung ist das Halteelement 12 eingefallen und blockiert nun den überstehenden Teil des Schenkels der Aushebefeder 11, so daß diese nicht zurückkehren kann. Bei Erreichen des Schließanschlags 16 wird der Versorgungsstrom des elektrischen Antriebsmotors 7 abgeschaltet und die Aushebefeder 11 stellt das Untersetzungsgetriebe 8 um ein geringes Maß zurück bis die weitere Rückstellbewegung eben vom Halteelement 12 gestoppt wird.It is further provided that the Aushebefeder 11 and the associated transmission gear 13 is associated with a closing stop 16 and an opening stop 17 is. In Fig. 1, the closed position, the one leg of the leg spring, which forms the Aushebefeder 11, of driving element 13a on the transmission gear 13 has been pressed against the closing stopper 16. In this position is the retaining element 12 has collapsed and now blocks the protruding Part of the leg of the Aushebefeder 11 so that they do not return can. Upon reaching the closing stop 16, the supply current of switched off electric drive motor 7 and the Aushebefeder 11 provides the reduction gear 8 by a small amount back to the other Return movement just stopped by the holding element 12.

Man kann bei dieser Konstruktion besonders gut realisieren, daß man die Steuerung des elektrischen Antriebsmotors 7 durch Überwachung des Motorstroms (Blockbetrieb) realisiert. Dann lassen sich Mikroschalter einsparen, was eine erhebliche Kostenersparnis bedeutet.One can realize with this construction particularly well, that the Control of the electric drive motor 7 by monitoring the motor current (Block operation) realized. Then microswitches can be saved, which means a significant cost savings.

Fig. 2 zeigt die Öffnungsstellung des Kraftfahrzeug-Türschlosses o. dgl. und zeigt dabei die Aushebefeder 11 mit ihrem beweglichen Schenkel am Öffnungsanschlag 17, wobei im bevorzugten Ausführungsbeispiel auch dort dann durch Blockbetrieb der elekrische Antriebsmotor 7 abgeschaltet worden ist. Im dargestellten Ausführungsbeispiel sind die Verhältnisse so, daß das Mitnahmeelement 13a, unterstützt von der Wirkung der Aushebefeder 11 am Öffnungsanschlag 17 zur Anlage kommt, also zwischen dem freien Schenkel der Aushebefeder 11 und dem Öffnungsanschlag 17 liegt.Fig. 2 shows the opening position of the motor vehicle door lock o. The like. And shows the Aushebefeder 11 with its movable leg on the opening stop 17, where in the preferred embodiment also there then switched off by block operation of the electric drive motor 7 is. In the illustrated embodiment, the conditions are such that the Carrier element 13a, supported by the action of the Aushebefeder 11 am Opening stop 17 comes to rest, so between the free leg the Aushebefeder 11 and the opening stop 17 is located.

Das zweite Getriebezahnrad 15 hat im dargestellten Ausführungsbeispiel eine Fangtasche 18 für eine Fangnase 19 am Halteelement 12. Im in Fig. 1 dargestellten Ausführungsbeispiel ist zu erkennen, daß die Fangnase 19 von der Fangtasche 18 am Getriebezahnrad 15 gehalten wird, so daß der das Halteelement 12 bildende, auf der Lagerachse 12b gelagerte Hebel auch unter Einfluß von Beschleunigungskräften nicht ungewollt nach oben ausweichen, also aufschlagen kann. Letzteres könnte nämlich bedeuten, daß bei entsprechender Kraft der Aushebefeder 11 plötzlich das Kraftfahrzeug-Türschloß ungewollt, lediglich durch die Aushebefeder 11 geöffnet würde.The second transmission gear 15 has a in the illustrated embodiment Catch pocket 18 for a catch nose 19 on the holding element 12. Im in Fig. 1 shown Embodiment can be seen that the catch nose 19 of the Catch pocket 18 is held on the transmission gear 15, so that the holding element 12 forming, mounted on the bearing axis 12b lever also under influence do not accidentally move upwards from acceleration forces, So can open. The latter could mean that with appropriate Force the Aushebefeder 11 suddenly the motor vehicle door lock unintentionally, would only be opened by the Aushebefeder 11.

Das Getriebezahnrad 15 wirkt mit der Fangtasche 18 also als zusätzliches Sicherungselement für das Halteelement 12. The transmission gear 15 thus acts with the catching pocket 18 as an additional securing element for the holding element 12.

Wird der elektrische Antriebsmotor 7 zum Öffnen des Kraftfahrzeug-Türschlosses o. dgl. in der in Fig. 1 dargestellten Position angesteuert, so wird das Getriebezahnrad 15 im Uhrzeigersinn gedreht und drückt die Fangnase 19 mittels der Seitenkante der Fangtasche 18 nach oben, so daß sich das Halteelement 12 vom freien Schenkel der Aushebefeder 11 löst und die Aushebefeder 11 freigibt. Gleichzeitig dreht sich das zweite Getriebezahnrad 15 entgegen dem Uhrzeigersinn, das Mitnahmeelement 13a verläßt die Aushebefeder 11, diese wird kurz darauf schlagartig freigegeben, sobald das Halteelement 12 ausgehoben worden ist. Von diesem Moment an wirkt die Rückstellkraft der Aushebefeder 11 zusätzlich zur Antriebskraft des elektrischen Antriebsmotors 7 im Öffnungssinne, so daß die Sperrklinke 5 blitzschnell und auch bei hohen Kräften am Schließkeil 3 ausgehoben wird.If the electric drive motor 7 for opening the motor vehicle door lock o. The like. Actuated in the position shown in Fig. 1, so will the transmission gear 15 is rotated clockwise and presses the catch nose 19 by means of the side edge of the catching bag 18 upwards, so that the holding element 12 of the free leg of Aushebefeder 11 triggers and the Aushebefeder 11 releases. At the same time, the second gear 15 rotates counter in the clockwise direction, the entrainment element 13a leaves the Aushebefeder 11, this is released shortly thereafter abruptly, as soon as the holding element 12 has been excavated. From this moment on, the restoring force acts the Aushebefeder 11 in addition to the driving force of the electric Drive motor 7 in the opening direction, so that the pawl 5 lightning fast and even at high forces on the striker 3 is excavated.

Das dargestellte Ausführungsbeispiel zeigt noch eine weitere, in gestrichelten Linien dargestellte Alternative, die dadurch gekennzeichnet ist, daß im Untersetzungsgetriebe 8, insbesondere am Getriebezahnrad 15, ein Freilauf 20, 21 realisiert ist, durch den gewährleistet ist, daß der Antriebsmotor 7 kurzzeitig anlaufen kann, ohne sofort eine abtriebsseitige Bewegung, insbesondere eine Bewegung des Getriebezahnrads 13, zu verursachen. Der Freilauf 20, 21 ist hier durch ein Mitnahmesegment 20 am einen Teil des Getriebezahnrades 15 und ein Freilaufsegment 21 an einem zweiten Teil des Getriebezahnrads 15, der gegen den ersten Teil drehbar ist, realisiert. Man erkennt im Übergang von Fig. 1 auf Fig. 2, daß beim Anlaufen des Antriebsmotors 7 der hier etwa 30° betragende Freilaufwinkel zwischen den Segmenten 20 und 21 aufgebraucht worden ist. Durch diesen Freilauf wird erreicht, daß das Halteelement 12 bereits ausgehoben wird, bevor die Bewegung des Antriebsmotors 7 auf das Getriebezahnrad 13 und damit auch die Sperrklinke 5 übertragen wird. Insbesondere bei einem selbsthemmenden Getriebe ist das zweckmäßig und hat überdies den Vorteil, daß der elektrische Antriebsmotor 7 ein geringes Anlaufmoment aufzubringen hat.The illustrated embodiment shows yet another, in dashed lines Lines illustrated alternative, which is characterized in that in the reduction gear 8, in particular on the transmission gear 15, a freewheel 20, 21st is realized, is ensured by the fact that the drive motor 7 for a short time can start without immediately a driven-side movement, in particular a To cause movement of the transmission gear 13. The freewheel 20, 21 is here by a driving segment 20 on a part of the transmission gear 15th and a freewheel segment 21 on a second part of the transmission gear 15, which is rotatable against the first part realized. One recognizes in the transition From Fig. 1 to Fig. 2, that at start-up of the drive motor 7 of here about 30 ° amount of freewheeling angle between the segments 20 and 21 is used up has been. By this freewheel is achieved that the holding element 12 is already excavated before the movement of the drive motor 7 the transmission gear 13 and thus also the pawl 5 is transmitted. In particular, in a self-locking gear that is appropriate and has the further advantage that the electric drive motor 7 a low Has to apply starting torque.

Das dargestellte Ausführungsbeispiel zeichnet sich in besonderer Weise noch dadurch aus, daß die Teile des Untersetzungsgetriebes 8 alle oder jedenfalls überwiegend aus Kunststoff bestehen. Die Ausführung aus Kunststoff ist möglich, weil auch bei hohen Kräften am Schließkeil 3 die Belastung des Untersetzungsgetriebes 8 im Ruhezustand gering ist.The illustrated embodiment is still outstanding in a special way characterized in that the parts of the reduction gear 8 all or at least predominantly made of plastic. The plastic version is possible, because even with high forces on the striker 3, the burden of the reduction gear 8 is low at rest.
