Description

Die Erfindung betrifft ein Kraftfahrzeugschloß mit den Merkmalen des Oberbegriffs von Anspruch 1. Ferner betrifft die Erfindung eine Schloßfalle für ein Kraftfahrzeugschloß mit den Merkmalen des Oberbegriffs von Anspruch 13.The invention relates to a motor vehicle lock having the features of the preamble of claim 1. Furthermore, the invention relates to a lock latch for a motor vehicle lock with the features of the preamble of claim 13.

Das in Rede stehende Kraftfahrzeugschloß kann irgendeinem Verschlußelement eines Kraftfahrzeugs zugeordnet sein. Beispiele hierfür sind eine Seitentür, die ggf. auch als Schiebetür ausgestaltet sein kann, eine Heckklappe, ein Heckdekkel, eine Motorhaube, o.dgl..The motor vehicle lock in question may be associated with any closure element of a motor vehicle. Examples include a side door, which may possibly be configured as a sliding door, a tailgate, a Heckdekkel, a hood, or the like.

Die bekannten Kraftfahrzeugschlösser weisen üblicherweise die Schließelemente Schloßfalle und Sperrklinke auf, die für das Zuhalten einer Kraftfahrzeugtür o.dgl. die entscheidenden Bauteile sind. Die Schloßfalle ist in eine Öffnungsstellung, eine Hauptschließstellung und, soweit vorgesehen, in eine Vorschließstellung verlagerbar. Die Sperrklinke läßt sich in einen ausgehobenen Zustand verstellen, in dem die Schloßfalle frei von der Sperrklinke ist. Ferner ist die Sperrklinke in einen eingefallenen Zustand bringbar, in dem sie die Schloßfalle in einer der beiden Schließstellungen hält.The known motor vehicle locks usually have the closing elements lock latch and pawl, or the like for locking a motor vehicle door. are the crucial components. The latch is in an open position, a main closing position and, insofar as provided, in a prelocking displaced. The pawl can be adjusted to a raised state in which the latch is free of the pawl. Furthermore, the pawl can be brought into a sunken state in which it holds the latch in one of the two closed positions.

Im geschlossenen Zustand der Kraftfahrzeugtür o.dgl. steht die Schloßfalle in haltendem Eingriff mit einem Schließkeil o.dgl.. Dabei ist das Kraftfahrzeugschloß üblicherweise an der Kraftfahrzeugtür o.dgl. und der Schließkeil an der Karosserie des Kraftfahrzeugs angeordnet.In the closed state of the motor vehicle door or the like. is the latch in holding engagement with a closing wedge or the like. In this case, the motor vehicle lock is usually the like on the motor vehicle door. and the closing wedge arranged on the body of the motor vehicle.

Für den haltenden Eingriff mit dem Schließkeil o.dgl. weist die Schloßfalle ein Einlaufmaul mit einem entsprechenden Eingriffsbereich auf. Beim Zuhalten der Kraftfahrzeugtür o.dgl. wird die Haltekraft über den Eingriffsbereich des Einlaufmauls der Schloßfalle auf den Schließkeil o.dgl. übertragen.For holding engagement with the closing wedge or the like. the latch has an inlet mouth with a corresponding engagement area. When locking the vehicle door or the like. the holding force on the engagement area of the inlet mouth of the lock latch on the closing wedge or the like. transfer.

Für den Eingriff zwischen der Schloßfalle und der Sperrklinke ist die Schloßfalle mit einer Hauptrast und einer ggf. vorhandenen Vorrast ausgestattet. Die Sperrklinke weist eine Rastnase auf, die beim Schließvorgang in Eingriff mit der ggf. vorhandenen Vorrast oder der Hauptrast kommt. Die Sperrklinke ist in der Regel in Einfallrichtung vorgespannt, so daß sie in einer Schnappbewegung einfällt.For the engagement between the latch and the pawl lock latch is equipped with a main catch and possibly existing pre-rest. The pawl has a latching nose, which comes into engagement with the existing pre-catch or the main catch during the closing process. The pawl is biased usually in the direction of incidence, so that it occurs in a snap action.

Insbesondere während des Schließvorgangs, aber auch beim Öffnen des Schlosses, entstehen bei dem in Rede stehenden Kraftfahrzeugschloß durch den Eingriff zwischen Sperrklinke und Schloßfalle sowie zwischen Schließkeil und Schloßfalle ungewünschte Geräusche, die vom Benutzer als Komforteinbuße gesehen werden.In particular, during the closing process, but also when opening the lock, arise in the motor vehicle lock in question by the engagement between the pawl and latch and between closing wedge and latch undesirable noise, which are seen by the user as a loss of comfort.

Während des Schließvorgangs trifft zunächst der Schließkeil o.dgl. auf die Schloßfalle, um diese von der Öffnungsstellung in die Hauptschließstellung zu verstellen, was bereits mit einem Geräusch verbunden ist. Anschließend fällt die Sperrklinke ein und trifft mit einem Schnappgeräusch auf die Schloßfalle, während sich die Schloßfalle noch in einer Überhubstellung befindet. Der von der Türdichtung erzeugte Dichtungsgegendruck sorgt dafür, daß der Schließkeil o.dgl. nun unter entsprechender Geräuschentwicklung auf einen hierfür vorgesehenen Eingriffsbereich des Einlaufmauls der Schloßfalle trifft. Dabei kommt die Rastnase der Sperrklinke in Eingriff mit der Hauptrast bzw. der Vorrast und sorgt wieder für eine entsprechende Geräuschentwicklung.During the closing process first meets the closing wedge or the like. on the latch to move from the open position to the main closed position, which is already associated with a noise. Then the pawl falls and hits with a snap sound on the latch while the latch is still in an overstroke position. The seal back pressure generated by the door seal ensures that the closing wedge or the like. now meets with appropriate noise on a designated engagement region of the inlet mouth of the latch. In this case, the locking lug of the pawl comes into engagement with the main catch or the pre-restraint and ensures again for a corresponding noise.

Zur Vermeidung der oben beschriebenen, ungewünschten Geräuschentwicklungen sind zahlreiche Maßnahmen bekannt geworden. Ein bekanntes Kraftfahrzeugschloß ( DE 23 20 351 A ) ist wie oben beschrieben ausgestaltet, wobei hier zur Geräuschdämpfung eine Ummantelung der Schloßfalle mit einem Kunststoffmaterial vorgesehen ist. Diese Ummantelung ist außerdem an bestimmten Stellen mit zusätzlichen Pufferausbildungen versehen. Die Ummantelung überstreicht auch den Eingriffsbereich des Einlaufmauls.Numerous measures have become known in order to avoid the undesired noise developments described above. A known motor vehicle lock ( DE 23 20 351 A ) is configured as described above, in which case a jacket of the latch is provided with a plastic material for noise damping. This sheath is also provided at certain points with additional Pufferausbildungen. The sheath also covers the engagement area of the inlet mouth.

Die Vermeidung des geräuschvollen Eingriffs zwischen der Rastnase der Sperrklinke und der Hauptrast der Schloßfalle wird in der EP 1 500 762 A2 behandelt. Hier weist die Ummantelung an der Anschlagfläche der Hauptrast eine geräuschdämpfende Ausformung auf.The avoidance of the noisy engagement between the detent of the pawl and the main catch of the latch is in the EP 1 500 762 A2 treated. Here, the casing on the abutment surface of the main catch on a noise-damping shape.

Das bekannte Kraftfahrzeugschloß ( DE 102 16 313 A1 ), von dem die Erfindung ausgeht, weist den grundsätzlich gleichen Aufbau wie oben beschrieben auf. Die Schloßfalle ist hier wieder mit einer Ummantelung versehen, die auch den Eingriffsbereich des Einlaufmauls überstreicht. In diesem Eingriffsbereich, aber auch in anderen Bereichen der Ummantelung, sind zusätzliche Puffertaschen vorgesehen. Die Puffertaschen sind zur Optimierung des Dämpfungsverhaltens mit einem Material ausgefüllt, das weicher ist als das Material der Ummantelung im übrigen.The known motor vehicle lock ( DE 102 16 313 A1 ), from which the invention proceeds, has basically the same construction as described above. The latch is here again provided with a jacket, which also covers the engagement area of the inlet mouth. In this engagement area, but also in other areas of the sheath, additional buffer bags are provided. The buffer pockets are filled to optimize the damping behavior with a material that is softer than the material of the shell otherwise.

Alle oben beschriebenen Maßnahmen betreffen in erster Linie die Reduzierung der Geräuschentwicklung beim Schließen und ggf. beim Öffnen der Kraftfahrzeugtür o.dgl.. Nicht berücksichtigt sind dabei Geräusche, die während des Fahrbetriebs durch eine Relativbewegung zwischen dem Schließkeil und der Schloßfalle entstehen. Solche Geräusche werden auch als "Knarzen" bezeichnet. Sie gehen zurück auf den bekannten "Stick-Slip-Effekt" und werden bestimmt einerseits durch den Reibwert der Materialpaarung zwischen Schließkeil und Schloßfalle und andererseits durch das Schwingungsverhalten der mechanischen Anordnung. Im übrigen sind mit der obigen Relativbewegung häufig ungewünschte Quietschgeräusche verbunden.All measures described above relate primarily to the reduction of noise when closing and possibly when opening the vehicle door or the like .. Not taken into account are noise that occurs during driving by a relative movement between the striker and the latch. Such sounds are also called "creaks". They go back to the well-known "stick-slip effect" and are determined on the one hand by the coefficient of friction of the material pairing between closing wedge and latch and on the other hand by the vibration behavior of the mechanical arrangement. Incidentally, undesirable squeaking noises are often associated with the above relative movement.

Bei einem bekannten Kraftfahrzeugschloß ( DE 102 20 225 A1 ) ist es zur Vermeidung des "Knarzens" vorgesehen, den metallischen Schließkeil o. dgl. und/oder ein mit dem Schließkeil o. dgl. zusammenwirkendes, metallisches Teil des Schlosses mit einer Oberflächenbeschichtung aus einer Hartstoffschicht zu versehen. Solche Hartstoffbeschichtungen von metallischen Oberflächen sind beispielsweise aus dem Bereich der Werkzeugherstellung, insbesondere der Herstellung von Bohr- oder Fräswerkzeugen bekannt. Mit dieser Maßnahme lassen sich eine hohe Oberflächenhärte einerseits und ein geringer Reibwert andererseits realisieren. Nachteilig dabei ist die Tatsache, daß die Notwendigkeit metallischer Oberflächen wieder zu ungewünschten Aufschlaggeräuschen zwischen Schließkeil o. dgl. und dem mit dem Schließkeil o. dgl. zusammenwirkenden Teil des Schlosses führen. Ferner ist der hohe fertigungstechnische Aufwand nachteilig.In a known motor vehicle lock ( DE 102 20 225 A1 ) it is provided to avoid the "creaking", the metallic locking wedge o. The like. And / or a cooperating with the closing wedge o. The like., Metallic part of the lock with a surface coating of a hard material layer. Such hard coatings of metallic surfaces are known, for example, in the field of tool production, in particular the production of drilling or milling tools. With this measure, a high surface hardness on the one hand and a low coefficient of friction on the other hand can be realized. The disadvantage here is the fact that the need for metallic surfaces again lead to unwanted impact noise between closing wedge o. The like. And with the closing wedge o. The like. Cooperating part of the castle. Furthermore, the high manufacturing expense is disadvantageous.

Bei einem weiteren bekannten Kraftfahrzeugschloß ( US 4,756,564 A ) ist es vorgesehen, daß die Ummantelung der Schloßfalle in einem Bereich des Einlaufmauls aus einem weicheren Material besteht als in einem anderen Bereich des Einlaufmauls. Der originär für den haltenden Eingriff mit dem Schließkeil o.dgl. vorgesehene Eingriffsbereich des Einlaufmauls ist bei allen Varianten dieses Kraftfahrzeugschlosses frei von Dämpfungsmaterial ausgestaltet.In another known motor vehicle lock ( US 4,756,564 A ), it is provided that the sheath of the latch in a region of the inlet mouth is made of a softer material than in another area of the inlet mouth. The original for the holding engagement with the closing wedge or the like. Provided engagement region of the inlet mouth is designed in all variants of this motor vehicle lock free of damping material.

Der Erfindung liegt das Problem zugrunde, das bekannte Kraftfahrzeugschloß derart auszugestalten und weiterzubilden, daß die durch die Relativbewegung zwischen dem Schließkeil o. dgl. und der Schloßfalle verursachte Geräuschentwicklung mit einfachen konstruktiven Mitteln reduziert wird.The invention is based on the problem to design the known motor vehicle lock such and further, that the noise caused by the relative movement between the closing wedge o. The like. And the lock trap is reduced by simple structural means.

Das obige Problem wird bei einem Kraftfahrzeugschloß gemäß dem Oberbegriff von Anspruch 1 durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst.The above problem is solved in a motor vehicle lock according to the preamble of claim 1 by the features of the characterizing part of claim 1.

Wesentlich ist die Erkenntnis, daß sich optimale Ergebnisse im Hinblick auf die erreichbare Geräuschminderung dadurch erreichen lassen, daß sich die Ummantelung der Schloßfalle aus zwei unterschiedlichen Materialien zusammensetzt.It is essential to realize that optimum results in terms of achievable noise reduction can be achieved by the fact that the sheath of the latch formed of two different materials.

Bei dem ersten Material handelt es sich vorzugsweise um einen weichelastischen Kunststoff mit gutem Eigendämpfungsverhalten. Dieses Material dient der Minderung der Eingriffsgeräusche zwischen Sperrklinke und Schloßfalle, beispielsweise des beim Einfallen der Sperrklinke entstehenden Geräuschs.The first material is preferably a soft elastic plastic with good self-damping behavior. This material serves to reduce the engagement noise between the pawl and latch, for example, the noise resulting from the engagement of the pawl.

Das zweite Material dient der Minderung der Eingriffsgeräusche zwischen Schließkeil und Schloßfalle. Dieses zweite Material findet also in erster Linie im Eingriffsbereich des Einlaufmauls Anwendung, in dem der Schließkeil o. dgl. mit der Schloßfalle in Eingriff kommt.The second material serves to reduce the engagement noise between the locking wedge and latch. This second material thus finds application primarily in the area of engagement of the inlet mouth in which the closing wedge or the like comes into engagement with the lock catch.

Verglichen mit dem ersten Material weist das zweite Material einen geringeren Reibwert und/oder eine größere Härte auf und wirkt daher dem Auftreten des Stick-Slip-Effekts zwischen Schließkeil o. dgl. und Schloßfalle entgegen. Ein "Knarzen", das durch die Relativbewegung zwischen Schließkeil und Schloßfalle auftritt, kann auf einfache Weise vermieden werden.Compared to the first material, the second material has a lower coefficient of friction and / or a greater hardness and therefore counteracts the occurrence of the stick-slip effect between the closing wedge o. The like. And latch. A "creaking" that occurs due to the relative movement between the locking wedge and the latch can be easily avoided.

Die Ummantelung kann auch in anderen Bereichen geräuschmindernd wirken. Insoweit ist die vorliegende Darstellung nicht beschränkend zu verstehen. Beispielsweise ist ferner erkannt worden, daß der Stick-Slip-Effekt auch im Bereich der Lagerung der Schloßfalle, also zwischen einem Lagerdorn und einer Lagerbohrung der Schloßfalle, auftreten kann. Bei der bevorzugten Ausgestaltung gemäß Anspruch 3 besteht die Ummantelung auch im Bereich der Lagerbohrung aus dem zweiten Material mit relativ geringem Reibwert und/oder großer Härte.The jacket can also reduce noise in other areas. In that regard, the present description is not restrictive. For example, it has also been recognized that the stick-slip effect can also occur in the region of the bearing of the latch, ie between a bearing mandrel and a bearing bore of the latch. In the preferred embodiment according to claim 3, the casing also in the region of the bearing bore of the second material with a relatively low coefficient of friction and / or high hardness.

Es ist also so, daß für unterschiedliche Geräuschquellen beim Betrieb des Kraftfahrzeugschlosses zwar grundsätzlich unterschiedliche Maßnahmen zu treffen sind. Vorschlagsgemäß läßt sich eine optimale Geräuschminderung, die allen unterschiedlichen Geräuschquellen Rechnung trägt, aber schlichtweg dadurch erreichen, daß die Schloßfallenummantelung - bei geeigneter Auslegung - aus zwei unterschiedlichen Materialien besteht.Thus, it is true that, in principle, different measures have to be taken for different noise sources during operation of the motor vehicle lock. According to the proposal, an optimal noise reduction, which takes into account all the different sources of noise, but simply by the fact that the Schloßfallenummantelung - with a suitable design - consists of two different materials.

Die bevorzugten Ausgestaltungen gemäß den Ansprüchen 8 bis 11 ermöglichen eine besonders einfache Fertigung der vorschlagsgemäßen Schloßfalle. Der aus dem zweiten Material bestehende Bereich der Ummantelung wird mit einem einfachen mechanischen Montageschritt an- oder eingesetzt.The preferred embodiments according to claims 8 to 11 allow a particularly simple production of the proposed lock latch. The existing of the second material portion of the sheath is on or used with a simple mechanical assembly step.

Nach einer weiteren Lehre, der ebenfalls eigenständige Bedeutung zukommt, wird die Schloßfalle des Kraftfahrzeugschlosses als solche beansprucht. Auf die obigen Ausführungen darf verwiesen werden.According to another teaching, which also has independent significance, the lock latch of the motor vehicle lock is claimed as such. Reference may be made to the above statements.

Das vorschlagsgemäße Kraftfahrzeugschloß weist neben den dargestellten Schließelementen Schloßfalle 1 und Sperrklinke 2 auch eine nicht dargestellte Schloßmechanik, ein nicht dargestelltes Schloßgehäuse etc. auf. Vorliegend ist allerdings in erster Linie die Ausgestaltung der Schloßfalle 1 von Interesse.The proposed motor vehicle lock has, in addition to the illustrated locking elements latch 1 and pawl 2 and a lock mechanism, not shown, a lock housing, not shown on. In the present case, however, the design of the latch 1 is of interest in the first place.

Die Schloßfalle 1 ist in eine Öffnungsstellung, eine Hauptschließstellung (Fig. 1, 3) und in eine Vorschließstellung verlagerbar. Hierfür weist die Schloßfalle 1 eine Hauptrast 3 und eine Vorrast 4 auf. Die Sperrklinke 2 ist in einen ausgehobenen Zustand, in dem die Schloßfalle 1 frei von der Sperrklinke 2 ist, und in einen eingefallenen Zustand (Fig. 1, 3), in dem die Sperrklinke 2 die Schloßfalle 1 in der Hauptschließstellung und in der Vorschließstellung hält, bringbar. Hierfür ist die Sperrklinke 2 mit einer Rastnase 5 in Eingriff mit der Hauptrast 3 und der Vorrast 4 bringbar.The latch 1 is in an open position, a main closed position ( Fig. 1 . 3 ) and in a Vorschließstellung relocatable. For this purpose, the latch 1 has a main catch 3 and a pre-rest 4. The pawl 2 is in a raised state, in which the latch 1 is free from the pawl 2, and in a sunken state ( Fig. 1 . 3 ), in which the pawl 2 holds the latch 1 in the main closed position and in the prelocking position, brought. For this purpose, the pawl 2 can be brought with a detent 5 in engagement with the main catch 3 and the pre-detent 4.

In der Hauptschließstellung und in der Vorschließstellung steht die Schloßfalle 1 in haltendem Eingriff mit einem Schließkeil 6, der auch als Schließbolzen oder als Schließbügel ausgestaltet sein kann. Für diesen haltenden Eingriff weist die Schloßfalle 1 ein Einlaufmaul 7 mit einem entsprechenden Eingriffsbereich 8 auf.In the main closed position and in the prelocking the latch 1 is in holding engagement with a striker 6, which can also be configured as a locking pin or as a striker. For this holding engagement, the latch 1 has an inlet mouth 7 with a corresponding engagement area 8.

Dem strukturellen Aufbau der Schloßfalle 1 kommt vorliegend besondere Bedeutung zu. Sie weist einen vorzugsweise metallischen Grundkörper 9 auf und ist im übrigen zur Minderung der Eingriffsgeräusche zwischen Sperrklinke 2 und Schloßfalle 1 und zwischen Schließkeil 6 und Schloßfalle 1 mit einem Dämpfungsmaterial ummantelt. Dabei besteht die Ummantelung 10 zur Minderung der Eingriffsgeräusche zwischen Sperrklinke 2 und Schloßfalle 1 aus einem ersten Material, vorzugsweise aus einem weichelastischen Kunststoff mit gutem Eigendämpfungsverhalten.The structural design of the lock catch 1 is of particular importance in the present case. It has a preferably metallic base body 9 and is otherwise encased to reduce the engagement noise between the pawl 2 and latch 1 and between the locking wedge 6 and latch 1 with a damping material. In this case, there is the sheath 10 to reduce the interference noise between pawl 2 and latch 1 of a first material, preferably made of a soft elastic plastic with good self-damping behavior.

Wesentlich ist die Tatsache, daß die Ummantelung 10 im Eingriffsbereich 8 des Einlaufmauls 7 aus einem zweiten Material besteht, das verglichen mit dem ersten Material einen geringeren Reibwert und ggf. eine größere Härte aufweist. Es wurde im allgemeinen Teil der Beschreibung erläutert, daß hiermit dem Auftreten des Stick-Slip-Effekts zwischen dem Schließkeil 6 und der Schloßfalle 1 entgegengewirkt werden kann. In den Fig. 1, 2, 3 ist der aus dem ersten Material bestehende Bereich der Ummantelung 10 mit 10a und der aus dem zweiten Material bestehende Bereich der Ummantelung 10 mit 10b bezeichnet.It is essential that the sheath 10 in the engagement region 8 of the inlet mouth 7 consists of a second material, which has a lower coefficient of friction and possibly a greater hardness compared to the first material. It has been explained in the general part of the description that hereby the occurrence of the stick-slip effect between the striker 6 and the latch 1 can be counteracted. In the Fig. 1, 2 . 3 the area of the casing 10 consisting of the first material is designated 10a and the area of the casing 10 made of the second material is designated 10b.

Es läßt sich den Darstellungen in Fig. 1, 3 entnehmen, daß die Haltekraft bei geschlossener Kraftfahrzeugtür o. dgl. vom unteren Teil der gabelartigen Ausformung der Schloßfalle 1 über den Eingriffsbereich 8 des Einlaufmauls 7, also über die aus dem zweiten Material bestehende Ummantelung 10, auf den unteren Teil des Schließkeils 6 wirkt. Dadurch, daß das zweite Material einen relativ geringen Reibwert und ggf. eine relativ große Härte aufweist, wirkt die Schloßfalle 1 im Eingriffsbereich 8 gewissermaßen als Gleitlager für den Schließkeil 6, so daß mit den im Fahrbetrieb auftretenden Relativbewegungen zwischen dem Schließkeil 6 und der Schloßfalle 1 kaum Geräuschentwicklungen verbunden sind.It can be the representations in Fig. 1 . 3 From the lower part of the fork-like shape of the lock catch 1 on the engagement portion 8 of the inlet mouth 7, ie on the existing shell of the second material shell 10, acts on the lower part of the closing wedge 6 in the closed motor vehicle door o. Characterized in that the second material has a relatively low coefficient of friction and possibly a relatively high hardness, the latch 1 in the engagement area 8 effectively acts as a sliding bearing for the striker 6, so that with the relative movements occurring between the striker 6 and the latch 1 during driving hardly any noise developments are connected.

Bei dem in den Fig. 1, 2, 3 dargestellten und insoweit bevorzugten Ausführungsbeispielen ist es so, daß die Schloßfalle 1 als um eine Drehfallenachse 11 drehbare Drehfalle ausgestaltet ist und daß die Drehfalle auf einem Lagerdorn 12 gelagert ist und hierfür eine Lagerbohrung 13 mit entsprechender Lagerfläche 14 aufweist. Dabei überstreicht die Ummantelung 10 die Lagerfläche 14 der Lagerbohrung 13. Die Ummantelung 10 im Bereich der Lagerbohrung 13 besteht aus dem zweiten Material, das verglichen mit dem ersten Material einen geringeren Reibwert und ggf. eine größere Härte aufweist. Mit dieser zusätzlichen Maßnahme läßt sich das Auftreten des Stick-Slip-Effekts auch zwischen der Lagerbohrung 13 und dem Lagerdorn 12 vermeiden.In the in the Fig. 1, 2 . 3 illustrated and so far preferred embodiments, it is such that the lock catch 1 is designed as a rotary latch axis rotatable about a catch 11 and that the catch is mounted on a bearing pin 12 and this has a bearing bore 13 with corresponding bearing surface 14. In this case, the sheath 10 passes over the bearing surface 14 of the bearing bore 13. The sheath 10 in the region of the bearing bore 13 consists of the second material, which has a lower coefficient of friction and possibly a greater hardness compared to the first material. With this additional measure, the occurrence of the stick-slip effect between the bearing bore 13 and the bearing mandrel 12 can be avoided.

Die vorschlagsgemäße Lösung läßt sich am besten dadurch realisieren, daß das erste Material und das zweite Material Kunststoffmaterialien sind. Dabei ist das erste Material vorzugsweise ein Thermoplastisches Polyester Elastomer (TPE). Als besonders vorteilhaft haben sich hier die kommerziell erhältlichen Werkstoffe Hytrel® 4774, Hytrel® 5526, Hytrel® 6356 von DuPont® oder Riteflex® 677 von Ticona® bewährt. Die jeweiligen Shore-Härten (ISO 868, 15s) liegen vorzugsweise zwischen 43 und 77, vorzugsweise bei 51 (Hytrel® 5526).The proposed solution can best be realized in that the first material and the second material are plastic materials. The first material is preferably a thermoplastic polyester elastomer (TPE). The commercially available materials Hytrel® 4774, Hytrel® 5526, Hytrel® 6356 from DuPont® or Riteflex® 677 from Ticona® have proved particularly advantageous. The respective Shore hardnesses (ISO 868, 15s) are preferably between 43 and 77, preferably 51 (Hytrel® 5526).

Die weichelastische Beschaffenheit dieser Materialien gewährleistet die Dämpfung impulsartiger Anregungen der Schloßfalle 1, beispielsweise beim Einfallen der Sperrklinke 2. Insbesondere werden die resultierenden Eigenschallabstrahlungen auf andere Bereiche der Schloßfalle 1 absorbiert.The soft-elastic nature of these materials ensures the damping of pulse-like suggestions of the latch 1, for example, when the pawl 2. The resulting intrinsic sound radiation is absorbed to other areas of the latch 1.

Das zweite Material dagegen ist wie erläutert auf die Vermeidung des Stick-Slip-Effekts hin optimiert. Bei dem zweiten Material handelt es sich vorzugsweise um einen Polymer-Gleitlagerwerkstoff. Vorteilhaft einsetzbar sind hier die kommerziell erhältlichen Werkstoffe Iglidur® G, Iglidur® W 300 und Iglidur® J von Igus®. Die Shore-D-Härten (DIN 53505) liegen in einem Bereich zwischen 74 und 81. Der Gleitreibwert dieser Werkstoffe liegt vorzugsweise zwischen 0,08 und 0,23.By contrast, the second material is optimized as described to avoid the stick-slip effect. The second material is preferably a polymer sliding bearing material. Can be advantageously used here, the materials commercially available Iglidur ® G, Iglidur ® W 300 and Iglidur ® J of Igus ®. The Shore D hardnesses (DIN 53505) lie in a range between 74 and 81. The sliding coefficient of friction of these materials is preferably between 0.08 and 0.23.

Die Fig. 3 und 4 zeigen eine Ausgestaltung der Schloßfalle 1 des vorschlagsgemäßen Kraftfahrzeugschlosses, die ganz besonders einfach zu fertigen ist. Dabei ist die Ummantelung 10 im Eingriffsbereich 8 des Einlaufmauls 7 als Einsatzelement 15 ausgestaltet. Beispielsweise kann das Einsatzelement 15 nach Art einer Lagerschale ausgestaltet sein. Dies ist in Fig. 4 dargestellt. Die Lagerschale erstreckt sich über einen Winkelbereich 16 zwischen 180° und 190°, vorzugsweise zwischen 182° und 185°.The 3 and 4 show an embodiment of the latch 1 of the proposed motor vehicle lock, which is very easy to customize. In this case, the casing 10 is configured as an insert element 15 in the engagement region 8 of the inlet mouth 7. For example, the insert element 15 may be designed in the manner of a bearing shell. This is in Fig. 4 shown. The bearing shell extends over an angular range 16 between 180 ° and 190 °, preferably between 182 ° and 185 °.

Ferner kann es vorteilhaft sein, die Ummantelung 10 im Bereich der Lagerbohrung 13 ebenfalls als Einsatzelement auszugestalten. Eine besonders bevorzugte Ausgestaltung sieht vor, daß die Ummantelung 10 im Eingriffsbereich 8 des Einlaufmauls 7 und die Ummantelung 10 im Bereich der Lagerbohrung 13 zusammenhängend, vorzugsweise als ein einheitliches, weiter vorzugsweise als einstückiges Einsatzelement 17, ausgestaltet sind. Die erstgenannte Variante ist in den Fig. 1, 2 dargestellt. Beispielsweise ist es denkbar, daß das einheitliche Einsatzelement 17 mit einer einzigen Montagebewegung in axialer Richtung montiert wird. Andere Montagearten sind denkbar.Furthermore, it may be advantageous to design the casing 10 in the region of the bearing bore 13 also as an insert element. A particularly preferred embodiment provides that the sheath 10 in the engagement region 8 of the inlet opening 7 and the casing 10 in the region of the bearing bore 13 are connected, preferably as a single, more preferably as a one-piece insert element 17, configured. The former variant is in the Fig. 1, 2 shown. For example, it is conceivable that the unitary insert element 17 is mounted with a single assembly movement in the axial direction. Other types of installation are conceivable.

Bei einem bevorzugten Kraftfahrzeugschloß gemäß Fig. 5 ist ein einheitliches Einsatzelement 17 vorgesehen, das die Ummantelung 10 im Eingriffsbereich 8 des Einlaufmauls 7 und die Ummantelung 10 im Bereich der Lagerbohrung 13 umfaßt und das auf besonders einfache Weise montierbar ist. Die Seitendarstellung der Schließelemente Schloßfalle 1 und Sperrklinke 2 dieses Kraftfahrzeugschlosses entspricht der Darstellung in Fig. 1.In a preferred motor vehicle lock according to Fig. 5 a uniform insert element 17 is provided, which comprises the sheath 10 in the engagement region 8 of the inlet mouth 7 and the sheath 10 in the region of the bearing bore 13 and which can be mounted in a particularly simple manner. The side view of the closing elements latch 1 and pawl 2 of this motor vehicle lock corresponds to the representation in Fig. 1 ,

Bei der in Fig. 5 dargestellten Ausgestaltung weist das Einsatzelement 17, wie bei der in Fig. 2 dargestellten Ausgestaltung, zwei parallel zwischen dem Eingriffsbereich 8 und der Lagerbohrung 13 verlaufende Schenkel 17a, 17b auf, die jeweils auf einer Flachseite der Schloßfalle 1 aufliegen. Die Schenkel 17a, 17b sind vorzugsweise jeweils flach nach Art eines Plättchens o. dgl. ausgestaltet. An die Schenkel 17a, 17b schließen sich einerends die Ummantelung 10 im Eingriffsbereich 8 und anderenends die Ummantelung 10 im Bereich der Lagerbohrung 13 an. Diese beiden Ummantelungen 10 erstrecken sich im wesentlichen senkrecht zu den Flachseiten der Schloßfalle 1.At the in Fig. 5 illustrated embodiment, the insert member 17, as in the in Fig. 2 illustrated embodiment, two parallel between the engaging portion 8 and the bearing bore 13 extending legs 17a, 17b, each resting on a flat side of the latch 1. The legs 17a, 17b are preferably flat in the manner of a small plate o. The like. Designed. At one end, the sheaths 17a, 17b join the sheath 10 in the engagement region 8 and at the other end the sheath 10 in the region of the bearing bore 13. These two sheaths 10 extend substantially perpendicular to the flat sides of the latch 1.

Bei der in Fig. 5 dargestellten und insoweit bevorzugten Ausgestaltung sind die beiden Schenkel 17a, 17b des Einsatzelements 17 über die Ummantelung 10 des Eingriffsbereichs 8, und nicht über die Ummantelung 10 im Bereich der Lagerbohrung 13 miteinander verbunden. Die Ummantelung 10 im Bereich der Lagerbohrung 13 wird durch zwei Hülsen 17c, 17d gebildet, die sich jeweils an einen Schenkel 17a, 17b des Einsatzelements 17 anschließen. Zwischen den beiden Hülsen 17c, 17d verbleibt stets ein Spalt 17e, so daß Fertigungstoleranzen unproblematisch sind.At the in Fig. 5 illustrated and so far preferred embodiment, the two legs 17a, 17b of the insert member 17 via the sheath 10 of the engagement portion 8, and not connected via the sheath 10 in the region of the bearing bore 13 with each other. The casing 10 in the region of the bearing bore 13 is formed by two sleeves 17 c, 17 d, which in each case adjoin a leg 17 a, 17 b of the insert element 17. A gap 17e always remains between the two sleeves 17c, 17d, so that manufacturing tolerances are unproblematic.

Zur Montage läßt sich das Einsatzelement 17 im Bereich der Ummantelung 10 für die Lagerbohrung 13 geringfügig aufbiegen. Dadurch läßt sich das Einsatzelement 17 über die Schloßfalle 1 schieben, bis die Hülsen 17c, 17d in die Lagerbohrung 13 einschnappen. Die Montage ist so mit minimalem Aufwand verbunden.For mounting, the insert element 17 can be bent slightly in the region of the casing 10 for the bearing bore 13. As a result, the insert element 17 can slide over the latch 1 until the sleeves 17c, 17d snap into the bearing bore 13. The assembly is connected with minimal effort.

Für die Ausgestaltung der Ummantelung im Bereich der Lagerbohrung 13 sind verschiedene weitere Varianten denkbar. Beispielsweise kann es vorgesehen sein, daß nur eine einzige Hülse 17c vorgesehen ist, die sich an einen der beiden Schenkel 17a, 17b anschließt. Diese Hülse erstreckt sich vorzugsweise über die gesamte Breite der Schloßfalle 1, also von einer Flachseite zu der anderen Flachseite der Schloßfalle 1.For the embodiment of the casing in the region of the bearing bore 13 various other variants are conceivable. For example, it may be provided that only a single sleeve 17c is provided, which adjoins one of the two legs 17a, 17b. This sleeve preferably extends over the entire width of the latch 1, that is, from one flat side to the other flat side of the latch 1.

Selbstverständlich können mehrere Einsatzelemente vorgesehen sein, beispielsweise eines für den Eingriffsbereich 8 und eines für die Lagerbohrung 13. Die Befestigung der Einsatzelemente 15, 17 kann durch Anklipsen, Anschweißen oder Ankleben erfolgen.Of course, a plurality of insert elements may be provided, for example one for the engagement region 8 and one for the bearing bore 13. The attachment of the insert elements 15, 17 may be done by clipping, welding or gluing.

Bei einer besonders bevorzugten Ausgestaltung ist es vorgesehen, daß der aus dem ersten Material bestehende Bereich der Ummantelung 10 an die Schloßfalle 1 angespritzt ist und daß der aus dem zweiten Material bestehende Bereich der Ummantelung 10 an- oder eingesetzt, vorzugsweise angeklipst, angeschweißt oder angeklebt ist. Es kann aber auch vorgesehen sein, daß die gesamte Ummantelung 10 an die Schloßfalle 1 angespritzt ist.In a particularly preferred embodiment, it is provided that the existing of the first material portion of the sheath 10 is molded onto the latch 1 and that the existing of the second material portion of the sheath 10 on or inserted, preferably clipped, welded or glued , But it can also be provided that the entire casing 10 is molded onto the latch 1.

Bei allen erläuterten Ausführungsbeispielen ist es vorzugsweise so, daß die Übergänge zwischen der aus dem ersten Material bestehenden Ummantelung 10a und der jeweiligen aus dem zweiten Material bestehenden Ummantelung 10b stetig, also ohne Kanten oder Absätze realisiert sind. Beispielsweise bilden die Schenkel 17a, 17b des Einsatzelements 17 eine Fläche mit der Ummantelung 10 im übrigen.In all illustrated embodiments, it is preferably such that the transitions between the existing of the first material sheath 10a and the respective existing of the second material sheath 10b are continuous, so realized without edges or heels. For example, the legs 17a, 17b of the insert element 17 form a surface with the casing 10 in the rest.

Es darf schließlich darauf hingewiesen werden, daß die Schloßfalle 1 des vorschlagsgemäßen Kraftfahrzeugschlosses auch als solche beansprucht wird. Insoweit darf auf die obigen Ausführungen verwiesen werden.Finally, it should be pointed out that the latch 1 of the proposed motor vehicle lock is claimed as such. In that regard, reference may be made to the above statements.
