Description

Kraftfahrzeugtürverschluss Motor vehicle door lock
Beschreibung :Description :
Die Erfindung betrifft einen Kraftfahrzeugtürverschluss, mit zumindest einem Gesperre mit im Wesentlichen einer Drehfalle mit einer Hauptrast und gegebenenfalls Vorrast für eine einfallende Sperrklinke, und mit einem Einlaufmaul sowie einem mit der Drehfalle zusammenwirkenden Schließbolzen. - Im Bezugsystem des Kraftfahrzeugtürverschlusses fährt der Schließbolzen in das Einlaufmaul ein. Grundsätzlich befindet sich der Schließbolzen an der Fahrzeugkarosserie wohingegen der Kraftfahrzeugtürverschluss demgegenüber mit seinem Einlaufmaul bewegt wird.The invention relates to a motor vehicle door lock, with at least one locking mechanism with essentially a rotary latch with a main catch and possibly preliminary catch for an incident pawl, and with an inlet mouth and a locking bolt cooperating with the rotary catch. - In the reference system of the motor vehicle door lock, the locking bolt moves into the inlet mouth. Basically, the locking bolt is located on the vehicle body, whereas the motor vehicle door lock, on the other hand, is moved with its inlet mouth.
Bei derartigen Kraftfahrzeugtürverschlüssen ist man stets um eine Geräuschdämmung bemüht, wenn einerseits der Schließbolzen in das Einlaufmaul einfährt und von der Drehfalle in ihrer Hauptraststellung festgehalten wird, während andererseits dafür Sorge getragen werden muss, dass die mit der Drehfalle zusammenwirkende Sperrklinke den Hauptrast- bereich nicht verlasst, wenn die Drehfalle im Zuge ihrer Schließbewegung einen Überhub durchführt. Ein solcher Überhub ist wegen der zwischen Drehfalle und Sperrklinke für die Schließ- und Öffnungsbewegungen erforderlichen Toleranzen notwendig.In motor vehicle door locks of this type, efforts are always made to reduce noise when, on the one hand, the locking bolt moves into the inlet mouth and is held in its main latching position by the catch, while on the other hand care must be taken to ensure that the pawl interacting with the catch does not leave the main catch area when the rotary latch performs an overstroke in the course of its closing movement. Such an overstroke is necessary because of the tolerances required between the rotary latch and the pawl for the closing and opening movements.
Der Erfindung liegt das technische Problem zugrunde, einen Kraftfahrzeugtürverschluss der eingangs beschriebenen Ausführungsform zu schaffen, der sich durch Geräuschdämmung und Funktionssicherheit im Zusammenwirken von Drehfalle, Sperrklinke und Schließbolzen auszeichnet.The invention is based on the technical problem of creating a motor vehicle door lock of the embodiment described at the outset, which is characterized by noise insulation and functional reliability in the interaction of rotary latch, pawl and locking bolt.
Zur Lösung dieses technischen Problems lehrt die Erfindung einen Kraftfahrzeugtürverschluss, mit zumindest einem Ge- sperre mit im Wesentlichen einer Drehfalle mit einer Haupt- rast und gegebenenfalls Vorrast für eine einfallende Sperrklinke* und mit einem in ein Einlaufmaul einfahrenden und mit der Drehfalle zusammenwirkenden Schließbolzen, wobei zumindest die Drehfalle eine Ummantelung aus Dämpfungswerkstoff aufweist und die Ummantelung eine der Hauptrast im Uhrzeigersinn nachgeordnete Puffertasche besitzt, die bis in den Bereich der Hauptrast unter Bildung eines Überhuban- schlages für die Sperrklinke herumgezogen ist.To solve this technical problem, the invention teaches a motor vehicle door lock, with at least one locking mechanism with essentially a rotary latch with a main catch and possibly preliminary catch for an incident pawl * and with a locking bolt that enters a mouth and interacts with the catch, whereby at least the rotary latch has a sheathing made of damping material and the sheathing has a buffer pocket arranged clockwise after the main catch, which is drawn around into the area of the main catch to form an overstroke stop for the pawl.
Diese Maßnahmen der Erfindung haben zunächst einmal zur Folge, dass der beim Schließen einer zugehörigen Kraftfahr- zeugtür im Bezugsystem des Kraftfahrzeugtürverschlusses in das Einlaufmaul einfahrende Schließbolzen beim Umgreifen von der Drehfalle durch die in die Ummantelung der Drehfalle integrierte Puffertasche gepuffert wird. Auf diese Weise sorgen nicht nur die aus Dämpfungswerkstoff bestehende Ummantelung sondern insbesondere auch die Puffertasche für einen geräuschreduzierenden Schließvorgang und auch eine erhebliche Geräuschminderung bei geschlossener Kraftfahrzeugtür. Darüber hinaus ist sichergestellt, dass die Funktionssicherheit des erfindungsgemäßen Kraftfahrzeugtürverschlusses auch dann gewährleistet ist, wenn die Drehfalle im Zuge des Schließvorganges einen Überhub durch- führt, weil der Uberhubanschlag für die Sperrklinke dafür sorgt, dass die Sperrklinke im Hauptrastbereich der Drehfalle verbleibt.These measures of the invention first of all have the consequence that when the associated motor vehicle door is closed in the reference system of the motor vehicle door lock, the locking bolt which enters the mouth of the motor vehicle is buffered when it is gripped by the rotary latch by the buffer pocket integrated in the casing of the rotary latch. In this way, not only the casing made of damping material but also, in particular, the buffer pocket ensure a noise-reducing closing process and also a considerable reduction in noise when the motor vehicle door is closed. In addition, it is ensured that the functional safety of the motor vehicle door lock according to the invention is also ensured if the rotary latch performs an overtravel in the course of the closing process because the overtravel stop for the pawl therefor ensures that the pawl remains in the main catch area of the rotary latch.
Die Drehfalle führt einen beschränkten Überhub, begrenzt durch einen Anschlag z. B. im Schlosskasten bzw. Schlossgehäuse, durch, nämlich bis ihr Uberhubanschlag auf die Sperrklinke trifft. Durch das Zusammenwirken des Überhub- anschlages auf der Drehfalle mit der Sperrklinke kann die Sperrklinke den Hauptrastbereich nicht verlassen und liegt nach Abschluss des Schließvorganges einwandfrei gegen die Hauptrast der federbeaufschlagten Drehfalle an.The catch trap leads to a limited overstroke, limited by a stop e.g. B. in the lock case or lock housing, namely, until your Uberhubanschlag hits the pawl. Due to the interaction of the overstroke stop on the rotary latch with the pawl, the pawl cannot leave the main catch area and, after the closing process has been completed, lies perfectly against the main catch of the spring-loaded catch.
Auch bei Überhub der Drehfalle wird eine Geräuschdämmung zwischen der Drehfalle und der Sperrklinke erreicht, weil der Uberhubanschlag der Sperrklinke auf der Drehfalle von der bis in diesen Bereich herumgezogenen Puffertasche gebildet wird, die also ein elastisches Abfangen nicht nur des Schließbolzens sondern auch der Sperrklinke bei Überhub im Wege einer Überhubkompensation gewährleistet.Even when the rotary latch is overstroke, noise insulation is achieved between the rotary latch and the pawl, because the overstroke stop of the pawl on the rotary latch is formed by the buffer pocket that has been drawn into this area, which therefore not only resiliently intercepts the locking bolt but also the pawl in the event of overstroke guaranteed by means of overstroke compensation.
Weitere erfindungswesentliche Merkmale sind im Folgenden aufgeführt. So kann auch die Sperrklinke zumindest teilweise von einem Dämpfungswerkstoff ummantelt sein, um die Geräuschdämmung weiter zu fördern. Bei diesem Dämpfungs- Werkstoff kann es sich um einen thermoplastischen Kunststoff wie beispielsweise Polyurethan handeln. Ferner kann die Ummantelung der Drehfalle eine Puffertasche auch zwischen der Hauptrast und der Vorrast aufweisen, um eine weitere Geräuschdämmung zu erreichen, wenn die Sperrklinke aus der Vorrast in die Hauptrast überführt wird. Endlich besteht bei dem erfindungsgemäßen Kraftfahrzeugtürver- schluss die Möglichkeit, das Übersetzungsverhältnis von Drehfalle/Sperrklinke zu reduzieren auf beispielsweise 2:1. Dadurch lässt sich einerseits eine kompaktere Bauweise erreichen, werden andererseits die kinematischen Verhältnisse optimiert .Further features essential to the invention are listed below. The pawl can also be at least partially encased in a damping material in order to further promote noise insulation. This damping material can be a thermoplastic, such as polyurethane. Furthermore, the casing of the rotary latch can also have a buffer pocket between the main catch and the preliminary catch, in order to achieve further noise insulation when the pawl is transferred from the preliminary catch to the main catch. Finally, there is a finally the possibility to reduce the gear ratio of the rotary latch / pawl to 2: 1, for example. On the one hand, this enables a more compact design to be achieved and, on the other hand, the kinematic conditions are optimized.
Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert. Es zeigen:The invention is explained in more detail below on the basis of a drawing illustrating only one exemplary embodiment. Show it:
Fig. 1 einen erfindungsgemäßen Kraftfahrzeugtürverschluss mit Schlosskasten, Drehfalle, Sperrklinke und angedeutetem Schließbolzen in Draufsicht,1 is a plan view of a motor vehicle door lock according to the invention with lock case, rotary latch, pawl and indicated locking bolt,
Fig. 2 einen vergrößerten Ausschnitt aus dem Gegenstand nach Fig. 1, wobei die Sperrklinke gegen den Uberhubanschlag an der Drehfalle anliegt undFig. 2 is an enlarged section of the object of FIG. 1, wherein the pawl rests against the overstroke on the rotary latch and
Fig. 3 den Gegenstand nach Fig. 2, wobei sich die Sperr- klinke in Hauptraststellung befindet.3 shows the object according to FIG. 2, the pawl being in the main detent position.
In den Figuren ist ein Kraftfahrzeugtürverschluss dargestellt, mit zumindest einem Gesperre mit im Wesentlichen einer Drehfalle 1 mit einer Hauptrast 2 und Vorrast 3 für eine einfallende Sperrklinke 4 und mit einem in ein Einlaufmaul 5 einfahrenden und mit der Drehfalle 1 zusammenwirkenden Schließbolzen 6, der lediglich angedeutet ist. Sobald die Sperrklinke 4 ausgehoben wird, dreht sich die federbeaufschlagte Drehfalle 1 im Uhrzeigersinn und folg- lieh in Offenstellung. Gleichzeitig wird dann der Schließbolzen 6 freigegeben, so dass eine zugehörige und nicht dargestellte Kraftfahrzeugtür geöffnet werden kann. Das Ausheben der Sperrklinke 4 kann rein mechanisch über ein nicht dargestelltes Hebelwerk oder auch motorisch, insbesondere elektromotorisch erfolgen. Im Zuge eines Schließ- Vorganges dreht sich die Drehfalle 1 entgegen Uhrzeigersinn entsprechend der Pfeilrichtung in Fig. 1 und kann dabei einen Überhub ausführen. Jedoch muss dafür Sorge getragen werden, dass die zugeordnete Sperrklinke 4 den Hauptrast- bereich nicht verlasst und schließlich in die Hauptrast 2 einwandfrei einfällt.In the figures, a motor vehicle door lock is shown, with at least one locking mechanism with essentially a rotary latch 1 with a main catch 2 and preliminary catch 3 for an incident pawl 4 and with a locking bolt 6 entering an inlet mouth 5 and interacting with the catch 1, which is only hinted at is. As soon as the pawl 4 is lifted, the spring-loaded rotary latch 1 rotates clockwise and subsequently borrowed in the open position. At the same time, the locking bolt 6 is then released, so that an associated and not Motor vehicle door shown can be opened. The pawl 4 can be lifted out purely mechanically via a lever mechanism (not shown) or also by motor, in particular by an electric motor. In the course of a closing process, the rotary latch 1 rotates counterclockwise according to the direction of the arrow in FIG. 1 and can thereby perform an overstroke. However, care must be taken to ensure that the assigned pawl 4 does not leave the main catch area and finally falls perfectly into the main catch 2.
Die Drehfalle 1 weist eine Ummantelung 7 aus Dämpfungswerkstoff auf. Diese Ummantelung 7 besitzt eine der Hauptrast 2 im Uhrzeigersinn nachgeordnete Puffertasche 8, die bis in den Bereich der Hauptrast 2 unter Bildung eines Überhuban- schlages 9 für die Sperrklinke 4 herumgezogen ist. Im Zuge der Schließbewegung und eines Überhubes schlägt also die Drehfalle 1 mit dem Uberhubanschlag 9 gegen die Sperrklinke 4 an. Dadurch ist sichergestellt, dass die Sperrklinke 4 den Hauptrastbereich nicht verlasst und schließlich einwandfrei in die Hauptrast 2 einfällt, zumal die Drehfalle 1 im Uhrzeigersinn federbeaufschlagt ist. - Auch die Sperrklinke 4 kann zumindest teilweise von einem Dämpfungswerkstoff 10 ummantelt sein. Es besteht aber auch die Möglich- keit, dass die Sperrklinke 4 eine Oberflachenbeschichtung mit Gleitlack oder einem Korrosionsschutz aufweist. Im Falle einer Teilummantelung kann diese Oberflachenbeschichtung dann auf die nicht ummantelten Bereiche beschränkt werden. Der Dämpfungswerkstoff 10 ist ein thermoplastischer Kunststoff, z. B. Polyurethan. Die Ummantelung 7 der Drehfalle 1 kann im Übrigen auch eine Puffertasche 11 zwischen Haupt- rast 2 und Vorrast 3 für die Sperrklinke 4 aufweisen. Diese Puffertasche 11 ist im Wesentlichen geradlinig ausgeführt, während die Puffertasche 8 unter Bildung des Überhuban- schlages 9 eine Abbiegung in Richtung auf die Hauptrast 2 aufweist. Beide Puffertaschen 8, 11 sind als schlitzförmige Taschen ausgebildet.The rotary latch 1 has a casing 7 made of damping material. This sheathing 7 has a buffer pocket 8 arranged downstream of the main catch 2 in a clockwise direction, which is drawn around into the area of the main catch 2 to form an overstroke stop 9 for the pawl 4. In the course of the closing movement and an overstroke, the rotary latch 1 strikes the pawl 4 with the overstroke stop 9. This ensures that the pawl 4 does not leave the main catch area and finally falls perfectly into the main catch 2, especially since the catch 1 is spring-loaded clockwise. - The pawl 4 can be at least partially covered by a damping material 10. However, there is also the possibility that the pawl 4 has a surface coating with lubricating varnish or corrosion protection. In the case of a partial covering, this surface coating can then be restricted to the areas that are not covered. The damping material 10 is a thermoplastic, e.g. B. polyurethane. The casing 7 of the rotary latch 1 can also have a buffer pocket 11 between the main catch 2 and the preliminary catch 3 for the pawl 4. This buffer pocket 11 is designed essentially in a straight line, while the buffer pocket 8 has a bend in the direction of the main catch 2, forming the overstroke stop 9. Both buffer pockets 8, 11 are designed as slit-shaped pockets.
Das Übersetzungsverhältnis Drehfalle l/Sperrklinke 4 ist auf 2:1 reduziert. - Schließlich erkennt man in der Fig. 1 einen Anschlag 12 im Schlosskasten bzw. Schlossgehäuse, welcher für die eingangs bereits beschriebene Beschränkung des Überhubs der Drehfalle 1 sorgt. Im vergrößerten Ausschnitt nach Fig. 1 ist dann noch eine Variante angedeutet, nach welcher die Puffertasche 8 mit Verstärkungsrippen 13 ausgerüstet sein mag, um einwandfrei und dauerhaft als Uberhubanschlag 9 fungieren zu können. The ratio of the rotary latch l / pawl 4 is reduced to 2: 1. - Finally, one can see in FIG. 1 a stop 12 in the lock case or lock housing, which ensures the limitation of the overlap of the rotary latch 1 already described at the beginning. In the enlarged section according to FIG. 1, a variant is then indicated, according to which the buffer pocket 8 may be equipped with reinforcing ribs 13 in order to be able to function properly and permanently as an overstroke stop 9.
