Description

Kraftfahrzeugtürverschluss Motor vehicle door lock
Beschreibung:Description:
Die Erfindung betrifft einen Kraftfahrzeugtürverschluss, mit zumindest einem Gesperre mit einer von einer Rückstellfeder beaufschlagten Drehfalle und einer Sperrklinke, und mit einem Einlaufmaul sowie einem mit der Drehfalle zusammenwirkenden Schließbolzen (an einer zugeordneten Kraftfahrzeugtür) . - Im Bezugsystem des Kraftfahrzeugtürverschlusses fährt der Schließbolzen in das Einlaufmaul ein. Regelmäßig befindet sich der Schließbolzen an der Kraftfahrzeugkarosserie, während der Kraftfahrzeugtürverschluss und folgerichtig das Einlaufmaul demgegenüber bewegt werden.The invention relates to a motor vehicle door lock, with at least one locking mechanism with a rotary latch acted upon by a return spring and a pawl, and with an inlet mouth and a locking bolt interacting with the rotary latch (on an associated motor vehicle door). - In the reference system of the motor vehicle door lock, the locking bolt moves into the inlet mouth. The locking bolt is regularly located on the motor vehicle body, while the motor vehicle door lock and consequently the inlet mouth are moved against it.
Es ist ein derartiger Kraftfahrzeugtürverschluss bekannt, bei dem das Einlaufmaul ein Dämpfungselement aufweist, welches dafür sorgt, dass der in das Einlaufmaul einfahrende und von der Drehfalle in ihre Hauptraststellung schließlich festgehaltene Schließbolzen in dieser Position geräuschmindernd fixiert wird (vgl. EP 0 336 034 A2) . - Unabhängig davon ist die Drehfalle von einer Rückstellfeder beaufschlagt, welche die Drehfalle nach dem Ausklinken der ihr zugeordneten Sperrklinke aus ihrer Schließstellung in die Offenstellung zurückdreht, wenn die Kraftfahrzeugtür geöffnet wird oder ist. Für diese Rückstellfeder ist an der Drehfalle ein Federanschlag angeformt. Das ist in material- und fertigungstechnischer Hinsicht aufwendig. - Hier will die Erfindung Abhilfe schaffen. Der Erfindung liegt die Aufgabe zugrunde, einen Kraftfahrzeugtürverschluss der eingangs beschriebenen Art zu schaffen, bei welcher die Drehfalle geräuscharm arbeitet und sich durch eine vereinfachte Bauweise auszeichnet.A motor vehicle door lock of this type is known in which the inlet mouth has a damping element which ensures that the locking bolt which enters the inlet mouth and is finally held in place by the catch in its main latching position is fixed in this position to reduce noise (cf. EP 0 336 034 A2). , - Independently of this, the catch is acted upon by a return spring which, after the pawl assigned to it has been released, turns the catch back out of its closed position into the open position when the motor vehicle door is or is open. For this return spring, a spring stop is formed on the rotary latch. This is complex in terms of materials and manufacturing technology. - The invention seeks to remedy this. The invention has for its object to provide a motor vehicle door lock of the type described in the opening paragraph, in which the catch operates quietly and is distinguished by a simplified design.
Diese Aufgabe löst die Erfindung bei einem gattungsgemäßen Kraftfahrzeugtürverschluss dadurch, dass die Drehfalle einen Dämpfungsanschlag aufweist, und dass dieser Dämpfungsanschlag auf seiner dampfungsabgewandten Seite zugleich als Federanschlag für die Rückstellfeder ausgebildet ist. - Die Erfindung geht von der Erkenntnis aus, dass bei einem Kraftfahrzeugtürverschluss eine erhöhte Geräuschreduzierung im Zuge insbesondere des Schließvorganges dann erreicht werden kann, wenn nicht nur ein Dämpfungselement für den Schließbolzen der zugeordneten Kraftfahrzeugtür vorgesehen ist, sondern darüber hinaus auch ein Dämpfungsanschlag für die Drehfalle. Dabei kann der Dämpfungsanschlag für die Drehfalle zugleich mit dem Dämpfungselement für den Schließbolzen zusammenarbeiten. Darüber hinaus kann ein solcher Dämpfungsanschlag zugleich als Federanschlag für die Rückstellfeder ausgebildet werden, so dass nicht länger ein separater Federanschlag als Ausformung an der Drehfalle erforderlich ist. Auf diese Weise wird eine in fertigungstechnischer Hinsicht vereinfachte Bauweise unter Materialeinsparung und Massenreduzierung erreicht. Nach einer bevorzugten Ausführungsform der Erfindung ist die Drehfalle mit einem Dämpfungswerkstoff, z. B. Kunststoff wie Polyurethan oder dergleichen ummantelt, wobei der Dämpfungs- und Federanschlag Bestandteil dieser Ummantelung sind. Eine solche Kunststoffummantelung mit Dämpfungs- undThis object is achieved by the invention in a generic motor vehicle door lock in that the rotary latch has a damping stop and that this damping stop is at the same time designed as a spring stop for the return spring on its side facing away from the damping. - The invention is based on the knowledge that with a motor vehicle door lock an increased noise reduction can be achieved in the course of the closing process in particular if not only a damping element is provided for the locking bolt of the associated motor vehicle door, but also a damping stop for the rotary latch. The damping stop for the rotary latch can also work together with the damping element for the locking bolt. In addition, such a damping stop can also be designed as a spring stop for the return spring, so that a separate spring stop is no longer required as a shape on the rotary latch. In this way, a construction which is simplified in terms of production technology is achieved with material savings and mass reduction. According to a preferred embodiment of the invention, the catch with a damping material, for. B. plastic such as polyurethane or the like sheathed, the damping and spring stop are part of this sheath. Such a plastic jacket with damping and
Federanschlag ist in fertigungstechnischer Hinsicht ver- hältnismäßig unproblematisch und in gewichtsmäßiger Hinsicht verhältnismäßig leicht, so dass auf diesem Wege die vorerwähnte Massenreduzierung erreicht wird, die für bewegte Teile von erheblicher Bedeutung ist.The spring stop is technically relatively unproblematic and relatively light in terms of weight, so that the aforementioned mass reduction is achieved in this way, which is of considerable importance for moving parts.
Weitere erfindungswesentliche Maßnahmen sind im Folgenden aufgeführt. So sieht die Erfindung vor, dass der Dämpfungsanschlag als eine im Fallenrandbereich angeordnete Anschlagrippe ausgebildet ist, die dem Umfang der Drehfalle über einen vorgegeben Teilabschnitt folgt. Die Anschlagrippe weist zweckmäßigerweise eine taschenartige Ausnehmung aus und funktioniert daher gleichsam selbst auch als Puffer, so dass ein erhöhter Dämpfungseffekt gewährleistet ist. Außerdem weist die Anschlagrippe an ihrem einen Ende eine bloße Anschlagfläche und an ihrem anderen Ende einen Federanschluss für die Rückstellfeder auf, z. B. eine Anschlussnase für die Schenkel einer als Schenkelfeder ausgebildeten Rückstellfeder.Further measures essential to the invention are listed below. The invention thus provides that the damping stop is designed as a stop rib arranged in the trap edge region, which follows the circumference of the rotary trap over a predetermined partial section. The stop rib expediently has a pocket-like recess and therefore also functions as a buffer itself, so that an increased damping effect is ensured. In addition, the stop rib has a bare stop surface at one end and a spring connection for the return spring at its other end, e.g. B. a connecting lug for the legs of a return spring designed as a leg spring.

In den Figuren ist ein Kraftfahrzeugtürverschluss dargestellt, mit zumindest einem Gesperre mit einer von einer Rückstellfeder 1 beaufschlagten Drehfalle 2 und einer mit der Drehfalle 2 zusammenwirkenden Sperrklinke 3 in einem Schlosskasten 4, ferner mit einem in ein Einlaufmaul 5 einfahrenden und mit der Drehfalle 2 zusammenwirkenden Schließbolzen 6 an einer zugeordneten Kraftfahrzeugtür, der lediglich angedeutet ist. Die Drehfalle 2 wird von der Rückstellfeder 1 in öffnendem Sinne und folglich Uhrzeigersinn beaufschlagt, der durch einen Pfeil angedeutet ist. Die Betätigung der Sperrklinke 3 kann rein mechanisch über ein nicht dargestelltes Hebelwerk oder auch motorisch, insbesondere elektromotorisch erfolgen.Fig. 2 shows an enlarged section of the object of FIG. 1 with return spring and damping stop for the catch. In the figures, a motor vehicle door lock is shown, with at least one locking mechanism with a rotary latch 2 acted upon by a return spring 1 and a pawl 3 cooperating with the rotary latch 2 in a lock case 4, furthermore with a locking bolt entering an inlet mouth 5 and interacting with the rotary latch 2 6 on an associated motor vehicle door, which is only indicated. The catch 2 is acted upon by the return spring 1 in the opening sense and consequently clockwise, which is indicated by an arrow. The pawl 3 can be actuated purely mechanically via a lever mechanism (not shown) or by motor, in particular by an electric motor.
Die Drehfalle 2 weist einen Dämpfungsanschlag 7 auf, der in Schließstellung gegen ein pufferartiges Dämpfungselement 8 vorf hrt. Dieses Dämpfungselement 8 ist in den Schlosskasten 4 eingesetzt. Der Dämpfungsanschlag 7 an der Drehfalle 2 ist auf seiner dampfungsabgewandten Seite als Federanschlag 7a für die Rückstellfeder 1 ausgebildet. Die Drehfalle 2 und gegebenenfalls teilweise auch die Sperrklinke 3 sind mit einem Dämpfungswerkstoff, z. B. Kunststoff wie Polyurethan ummantelt, wobei der Dämpfungsanschlag 7 und der Federanschlag 7a Bestandteil dieser Ummantelung 9 sind. Der Dämpfungsanschlag 7 ist als eine im Fallenrandbereich angeordnete Anschlagrippe ausgebildet, die dem Umfang der Drehfalle 2 über einen Teilabschnitt folgt. Diese Anschlagrippe 7 weist eine taschenartige Ausnehmung 10 auf und zeichnet sich daher selbst auch durch Pufferwirkung aus.The rotary latch 2 has a damping stop 7 which, in the closed position, performs against a buffer-like damping element 8. This damping element 8 is inserted in the lock case 4. The damping stop 7 on the rotary latch 2 is designed on its side facing away from the steam as a spring stop 7a for the return spring 1. The catch 2 and possibly partially the pawl 3 are with a damping material, for. B. plastic such as polyurethane sheathed, the damping stop 7 and the spring stop 7a are part of this sheath 9. The damping stop 7 is designed as a stop rib arranged in the trap edge region, which follows the circumference of the catch 2 over a partial section. This stop rib 7 has a pocket-like recess 10 and is therefore also characterized by a buffer effect.
Die Anschlagrippe 7 weist an ihrem einen dämpfungsseitigen Ende eine einfache Anschlagfläche 7b und an ihrem anderen Ende einen Federanschluss 11, z. B. eine Anschlussnase für die beispielsweise als Schenkelfeder ausgebildete Rückstellfeder 1 auf. Im Ganzen wird ein reibungs- und geräuscharm arbeitendes Gesperre verwirklicht, welches sich durch einfache und funktionsgerechte Bauweise auszeichnet.The stop rib 7 has on its one damping side End a simple stop surface 7b and at its other end a spring connection 11, z. B. a connecting lug for the restoring spring 1, for example, a leg spring. Overall, a friction and low-noise locking mechanism is implemented, which is characterized by a simple and functional design.
In der Fig. 1 erkennt man noch einen Anschlag 12 im Schlosskasten bzw. Schlossgehäuse, welcher eine Überhubbe- wegung der Drehfalle 2 beschränkt bzw. begrenzt. Dagegen dient der Dämpfungsanschlag 7 dazu, die Öffnungsbewegung der Drehfalle 2 zu stoppen bzw. zu beschränken. Darüber hinaus mag der Dämpfungsanschlag 7 mit einer oder mehreren Verstärkungsrippen 13 ausgerüstet sein, die lediglich ange- deutet sind. 1 also shows a stop 12 in the lock case or lock housing, which limits or limits an overstroke movement of the rotary latch 2. In contrast, the damping stop 7 serves to stop or restrict the opening movement of the rotary latch 2. In addition, the damping stop 7 may be equipped with one or more reinforcing ribs 13, which are only indicated.
