Description
Die Erfindung betrifft eine Trägerplatte mit einem Lagerdorn für Sperrteile, insbesondere eines Kraftfahrzeug-Türschlosses, wobei die Sperrteile an dem eine Lagerachse bildenden Lagerdorn wenigstens teilweise drehbar lagerbar sind. Des weiteren betrifft die Erfindung ein Kraftfahrzeug-Türschloss mit an der Trägerplatte an einem solchen Lagerdorn gelagerten Sperrteilen.The invention relates to a carrier plate with a bearing pin for locking parts, in particular a motor vehicle door lock, wherein the locking parts are at least partially rotatably mounted on the bearing axis forming a bearing pin. Furthermore, the invention relates to a motor vehicle door lock with mounted on the support plate on such bearing arbor locking parts.
Kraftfahrzeug-Türschlösser, die üblicherweise Verwendung finden, werden als separates zu montierendes Teil geliefert, welches dann beim Fahrzeughersteller eingesetzt wird. Das Kraftfahrzeug-Türschloss beinhaltet dabei zumeist bewegte Teile, die ein sicheres Verschließen der Fahrzeug-Tür sicherzustellen haben. Dabei werden zumeist Türschloss-seitige Drehfallen eingesetzt die mit Karosserie-seitigen Bolzen oder Kloben zusammenwirken um die Kraftfahrzeugtür zu verschließen.Motor vehicle door locks, which are commonly used, are supplied as a separate part to be mounted, which is then used by the vehicle manufacturer. The motor vehicle door lock contains mostly moving parts that have to ensure a secure closing of the vehicle door. In this case, mostly door lock-side rotary traps are used which cooperate with body-side bolts or cocks to close the vehicle door.
Die Drehfallen müssen dabei große Kräfte aufnehmen da ein Einbruch ebenso verhindert werden soll, wie ein ungewünschtes aufspringen der Tür bei einem Unfall. Daher müssen die Drehfallen und die die Drehfallen lagernden Teile im Kraftfahrzeug-Türschloss stabil gelagert werden.The rotary traps must absorb large forces because a break-in is also to be prevented, as an unwanted jump on the door in an accident. Therefore, the rotary latches and the parts stored in the rotary latches must be stably stored in the motor vehicle door lock.
Kostenaufwändig bei der Herstellung von üblichen Türschlössern ist die hohe Anzahl von eingesetzten Einzelteilen die separat montiert werden müssen. Dabei werden an die Einzelteile und an die zusammengesetzte Einheit hohe mechanische Anforderungen bezüglich der Belastbarkeit, insbesondere im Crashfall, gestellt.Costly in the production of conventional door locks is the high number of used items that need to be mounted separately. In this case, high mechanical requirements with regard to the load capacity, in particular in the event of a crash, are placed on the individual parts and on the assembled unit.
In modernen Fahrzeugen wird zudem immer mehr Wert darauf gelegt, dass bewegte Teile, wie die Kraftfahrzeug-Türschlösser, weitgehendst geräuscharm arbeiten. Herkömmliche Kraftfahrzeug-Türschlosser müssen daher mit zusätzlich zu montierenden Mitteln oder mit aufwändigen geräuscharmen Halterungen versehen werden. All diese vorhergenannten Maßnahmen und Vorgaben verursachen zusätzliche Kosten durch hohe Teilevielfalt und damit verbundenen Herstellungsschritten.In modern vehicles, more and more emphasis is placed on the fact that moving parts, such as the motor vehicle door locks, work largely quiet. Conventional motor vehicle door locksmiths must therefore be provided with additional means to be mounted or with elaborate low-noise brackets. All of these aforementioned measures and specifications cause additional costs due to high variety of parts and associated manufacturing steps.

Der Erfindung liegt die Aufgabe zugrunde, die oben genannten Nachteile zu verringern und eine verbesserte Lagerung für Sperrteile sowie verbesserte Kraftfahrzeug-Türschlösser zur Verfügung zu stellen und dabei insbesondere die Gesamtprozessfolge der Herstellung bezüglich ihrer Wirtschaftlichkeit und Qualität zu verbessern.The invention has for its object to reduce the above-mentioned disadvantages and to provide an improved storage for locking parts and improved motor vehicle door locks and in particular to improve the overall process sequence of the production in terms of their efficiency and quality.
Diese Aufgabe wird durch eine Trägerplatte mit einem Lagerdorn für Sperrteile nach Anspruch 1 und ein Kraftfahrzeug-Türschloss mit an der Trägerplatte gelagerten Sperrteilen nach Anspruch 10 gelöst.This object is achieved by a support plate with a bearing pin for locking parts according to claim 1 and a motor vehicle door lock with mounted on the support plate locking parts according to claim 10.
Erfindungsgemäß ist vorgesehen, dass eine wenigstens ein Sperrteil tragende Trägerplatte aus einem formstabilen Material, insbesondere einem Metall, vorgesehen ist, aus der eine laschenförmige Ausformung im wesentlichen in Achsenrichtung der Lagerachse ausgeformt ist, wobei der Lagerdorn durch eine Kunststoff-Umspritzung bzw. -Anspritzung um die laschenförmige Ausformung ausgebildet ist.According to the invention, it is provided that a support plate carrying at least one blocking part is provided of a dimensionally stable material, in particular a metal, from which a tab-shaped formation is formed essentially in the axial direction of the bearing axis, wherein the bearing mandrel is encapsulated by a plastic encapsulation or injection the tab-shaped formation is formed.
Die Erfindung schlägt vor, die Ausgestaltung der sonst als separat zu montierenden massiven metallenen Achse ausgebildeten Lagerung durch ein Kunststoff-umspritztes, aus der Trägerplatte ausgeformtes Teil herzustellen. Durch die Kunststoff-Umspritzung des Lagerdorns wird die Geräuschentwicklung der Drehfalle selber schon in deren Lagerung erheblich gedämpft. Die notwendige hohe mechanische Festigkeit ist durch die laschenförmige Ausformung aus der Trägerplatte gegeben.The invention proposes to produce the configuration of the otherwise designed to be mounted as a separate solid metal axle storage by a plastic-molded, molded from the support plate part. Due to the plastic encapsulation of the bearing mandrel, the noise of the rotary latch itself is significantly attenuated even in their storage. The necessary high mechanical strength is given by the tab-shaped formation of the support plate.
Durch die Verwendung des Kunststoffs wird zudem Gewicht eingespart, was wiederum günstig auf der Kostenseite zu buche schlägt. Der Kunststoff hat neben der starken Geräuschdämpfung auch hervorragende Eigenschaften bezüglich der Temperaturbeständigkeit, Stabilität und Verzugsfreiheit.By using the plastic weight is also saved, which in turn proposes favorable on the cost side to beech. The plastic has in addition to the strong noise damping and excellent properties in terms of temperature resistance, stability and freedom from distortion.
Als Kunststoffe können beispielsweise technische Kunststoffe und/oder glasfaser- oder kohlefaserverstärkte Kunststoffe aber auch Elastomere gewählt werden.As plastics, for example, engineering plastics and / or glass fiber or carbon fiber reinforced plastics but also elastomers can be selected.
Die Herstellung der Lagerachse erfolgt bevorzugterweise durch eine Umspritzung die sich der sogenannten Outsert-Technik bedient. Dabei wird das Kunststoff-Material direkt um die zu umschließenden Teile gespritzt, wobei Kanten, Öffnungen oder Vorsprünge an dem metallenen Träger als Verankerung bzw. Ansatz für den Kunststoff dienen. Eine Montage der gespritzten Teile entfällt damit. So werden viele Arbeitsschritte und die Materialien für die sonst anfallenden Teile bei der Montage eingespart und aufwändige Logistik und Lagerhaltung der sonst einzeln herzustellenden und zu liefernden Teile kann ebenfalls eingespart werden.The production of the bearing axis is preferably carried out by an encapsulation using the so-called outsert technique. In this case, the plastic material is injected directly around the parts to be enclosed, with edges, openings or projections on the metal support serve as anchoring or approach for the plastic. An assembly of the sprayed parts is thus eliminated. Thus, many steps and the materials for the otherwise accruing parts are saved during assembly and complex logistics and warehousing of otherwise individually manufactured and to be delivered parts can also be saved.
Durch die Outsert-Technologie können hochpräzise Formen hergestellt werden, die sehr geringe Toleranzen aufweisen. Da auch die Montage entfällt werden die damit verbundenen möglichen Toleranzen bei den Geometrien ebenfalls vermieden.Outsert technology can produce high-precision shapes with very tight tolerances. Since the assembly is omitted, the associated possible tolerances in the geometries are also avoided.
Nach einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die laschenförmige Ausformung aus der Trägerplatte freigestanzt und aufgestellt worden ist.According to a preferred embodiment of the invention it is provided that the tab-shaped formation has been punched out of the carrier plate and placed.
Von Vorteil bildet die Umspritzung der laschenförmige Ausformung einen zylinderförmigen Lagerdorn.Advantageously, the encapsulation of the tab-shaped formation forms a cylindrical bearing mandrel.
Ebenso von Vorteil bildet erfindungsgemäß die Umspritzung einen Lagerdorn, der einen kleineren inneren Durchmesser und einen größeren äußeren Durchmesser aufweist, wobei der größere Durchmesser in Richtung der Haupt-Kraftübertragungsrichtung des Sperrteils auf den Lagerdorn vorgesehen ist.Likewise advantageous according to the invention forms the encapsulation a bearing mandrel, which has a smaller inner diameter and a larger outer diameter, wherein the larger diameter is provided in the direction of the main power transmission direction of the locking member on the bearing mandrel.
Durch einen so gewählten größeren Durchmesser kann die laschenförmige Ausformung breiter gewählt werden, was die ableitbaren Kräfte weiter erhöht.By choosing a larger diameter, the tab-shaped formation can be made wider, which further increases the dissipative forces.
Dem folgend ist in dem Sperrteil korrespondierend mit dem Lagerdorn eine im wesentlichen schwalbenschwanzförmige Lageraufnahme-Öffnung vorgesehen, die entsprechend einen kleineren inneren Durchmesser und einen größeren äußeren Durchmesser aufweist. Ein weiterer Vorteil des Zusammenwirkens von so ausgestaltetem Lagerdorn und Lageraufnahme-Öffnung ist, dass ein definierter Anschlag für das Sperrteil entsteht.The following is provided in the locking member corresponding to the bearing mandrel a substantially dovetail-shaped bearing receiving opening, which has a corresponding smaller inner diameter and a larger outer diameter. Another advantage of the interaction of bearing arbor and bearing receiving opening designed in this way is that a defined stop for the locking part is produced.
Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, dass das Ende des Lagerdorns in einer Ausnehmung in einem die Sperrteile wenigstens teilweise umschließenden Schlossgehäuse gelagert ist.An advantageous embodiment of the invention provides that the end of the bearing mandrel is mounted in a recess in a lock housing at least partially enclosing the lock housing.
Bevorzugterweise sind die Sperrteile eine Drehfalle und/oder eine Sperrklinke eines Kraftfahrzeug-Türschlosses.Preferably, the locking parts are a rotary latch and / or a pawl of a motor vehicle door lock.
Nach einem weiteren Aspekt der Erfindung ist ein Kraftfahrzeug-Türschloss mit an einer Trägerplatte gelagerten Sperrteilen vorgeschlagen nach einem der Ansprüche 1 bis 9.According to a further aspect of the invention, a motor vehicle door lock with mounted on a support plate locking parts is proposed according to one of claims 1 to 9.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, dass auf der Trägerplatte und/oder einem die Sperrteile auf der Trägerplatte wenigstens teilweise umschließenden Schlossgehäuse Führungsrillen und/oder Führungserhebungen und/oder Anschläge für die Sperrteile und/oder andere bewegte Teile des Kraftfahrzeug-Türschlosses durch eine aufgebrachte Kunststoff-Umspritzung bzw. -Anspritzung vorgesehen sind.A preferred embodiment of the invention provides that guide grooves and / or guide elevations and / or stops for the locking parts and / or other moving parts on the carrier plate and / or the locking parts on the support plate at least partially enclosing lock housing of the motor vehicle door lock are provided by an applied plastic encapsulation or -Anspritzung.
Von Vorteil sind die Sperrteile teilweise mit einer Kunststoff-Umspritzung versehen, welche Kunststoff-Umspritzung insbesondere durch Outsert-Technik aufgebracht ist.Advantageously, the locking parts are partially provided with a plastic encapsulation, which plastic encapsulation is applied in particular by outsert technology.
Eine besonders vorteilhafte Weiterbildung der Erfindung sieht vor, dass die Trägerplatte an ihren äußeren Kanten und/oder an Kanten von Öffnungen oder Ausstanzungen wenigstens teilweise mit einer die Kanten umhüllenden Kunststoff-Umspritzung versehen ist, welche Kunststoff-Umspritzung insbesondere durch Outsert-Technik aufgebracht ist. Hierdurch können mögliche Verletzungen vermieden werden, ein sonst gebotenes aufwändiges Entgraten kann in vielen Fällen entfallen. Die Umspritzung der Kanten dient gleichzeitig als Korrosionsschutz, da die offenen Stanz- oder Schnittflächen von der Luft abgeschlossen werden. Durch die Umspritzung ist auch Material mit größerer Dicke eingesetzt werden, dessen Kanten aufgrund der Bearbeitung - beispielsweise Stanzen - nicht über die zuvor aufgebrachte Schutzschicht z.B. eine Zinkschicht verfügt. Durch die Umspritzung der Kanten kann aber auch im sichtbaren Bereich des Kraftfahrzeug-Türschlosses eine Verbesserung des Designs erreicht werden, da Oberflächen und Formungen nach belieben vorgenommen werden können.A particularly advantageous development of the invention provides that the support plate is provided at its outer edges and / or edges of openings or punched out at least partially with a plastic encapsulation surrounding the edges, which plastic encapsulation is applied in particular by outsert technology. As a result, possible injuries can be avoided, an otherwise required complex deburring can be omitted in many cases. The encapsulation of the edges also serves as corrosion protection, since the open punched or cut surfaces are closed by the air. The encapsulation also makes it possible to use material of greater thickness whose edges, due to the processing, for example punching, do not penetrate over the previously applied protective layer, e.g. has a zinc layer. By encapsulation of the edges but also in the visible range of the motor vehicle door lock, an improvement of the design can be achieved because surfaces and shapes can be made at will.
Zur Minderung von Geräuschen oder Reibung ist nach einer weiteren vorteilhaften Ausgestaltung der Erfindung vorgesehen, dass wenigstens teilweise zwischen den Sperrteilen und der Trägerplatte und/oder dem Schlosskasten und/oder dem Schlossgehäuse flächig eine Kunststoff-Umspritzung, insbesondere durch Outsert-Technik, aufgebracht ist. Durch eine solche auch Außen aufgebrachte Umspritzung kann neben der weiteren Geräuschdämpfung auch ein verbessertes Design des ganzen Kraftfahrzeug-Türschlosses erreicht werden.To reduce noise or friction is provided according to a further advantageous embodiment of the invention that at least partially between the locking parts and the support plate and / or the lock case and / or the lock housing a plastic encapsulation, in particular by outsert technique applied. By such an externally applied encapsulation, an improved design of the entire motor vehicle door lock can be achieved in addition to the further noise damping.
Eine bezüglich der Herstellung effiziente Variante sieht vor, dass die Kunststoff-Umspritzungen an der Trägerplatte in einem einzigen Herstellungsschritt in Outsert-Technik hergestellt sind.An efficient variant with regard to the production provides that the plastic encapsulation on the carrier plate in a single manufacturing step in outsert technology are made.
Von Vorteil ist die Trägerplatte durch einen Schlosskasten eines Kraftfahrzeug-Türschlosses gebildet. Bei Anwendung der Outsert-Technologie kann auch das die an der Trägerplatte gelagerten Sperrteile umschließende Schlossgehäuse in einem Stück hergestellt werden.Advantageously, the support plate is formed by a lock case of a motor vehicle door lock. When using the Outsert technology, the lock housing enclosing the locking plate mounted on the support plate can be manufactured in one piece.
Weitere Vorteile, Besonderheiten und zweckmäßige Weiterbildungen der Erfindung ergeben sich aus den weiteren Unteransprüchen oder deren Unterkombinationen.Further advantages, features and expedient developments of the invention will become apparent from the other dependent claims or their sub-combinations.

Die Umspritzung 5 des Lagerdorns 1a bildet einen kleineren inneren Durchmesser und einen größeren äußeren Durchmesser. Dementsprechend ist in der Drehfalle 21a korrespondierend mit dem Lagerdorn 1a eine im wesentlichen schwalbenschwanzförmige Lageraufnahme-Öffnung 23 vorgesehen. Durch diese Anordnung wird ein Anschlag für die Drehfalle gebildet, sodass diese nicht über ein vorgegebenes Maß hinaus um die Lagerachse gedreht werden kann.The
Durch diese Ausgestaltung kann die laschenförmige Ausformung 41 sehr breit ausgeführt werden, ohne, dass die gesamte Lageraufnahme-Öffnung 23 den größeren Durchmesser 12 des Lagerdorns 1a aufweisen müsste. Vorteil hierbei ist, dass in Richtung der Haupt-Kraftübertragungsrichtung F größere Kräfte durch die laschenförmige Ausformung 41 und die Kunststoff-Umspritzung 5 an die Trägerplatte übertragen werden können.As a result of this configuration, the lug-shaped
