Description
Die Erfindung bezieht sich auf eine Haltestangenlagerung für Kraftwagentürfeststeller, bestehend aus einer Scharnieraugenbohrung in der Türhaltestange eines Türfeststellers und einem mit wenigstens einer Scharnieraugenbohrung versehenen feststehend an einem der beiden Türanordnungsteile, Tür oder Türsäule befestigten Lagerbock sowie einem einerseits in die Scharnieraugenbohrung in der Türhaltestange und andererseits in die Scharnieraugenbohrung des Lagerbockes eingreifenden Lagerstift, der vermittels einer federnd elastischen Abstützung in einer der Scharnieraugenbohrungen mit Laufsitz gelagert ist und bei der die Türhaltestange in Achsrichtung ihrer Lagerung federnd elastisch gegen den Lagerbock abgestützt ist (vgl. Oberbegriff des Anspruchs 1). Eine solche Haltestangenlagerung ist aus der EP-A-0 299 147 bekannt.The invention relates to a support rod mounting for motor vehicle door locks, consisting of a hinge eye bore in the door support rod of a door lock and a bearing block provided with at least one hinge eye bore fixed to one of the two door arrangement parts, door or door pillar, and on the one hand in the hinge eye bore in the door support rod and on the other hand in the hinge eye bore of the bearing block engaging bearing pin, which is mounted by means of a resilient support in one of the hinge eye holes with a seat and in which the door support rod is resiliently supported in the axial direction of its storage against the bearing block (cf. preamble of claim 1). Such a handrail mounting is known from EP-A-0 299 147.
Bei der Lagerung der Türhaltestangen von Kraftwagentürfeststellern ergibt sich eine besondere Problematik daraus, daß die angrenzenden Karosserieteile, Tür und Türsäule jeweils Hohlkörper sind, die als Resonanzkörper wirkend auch die geringste Geräuschentwicklung in der Lagerung der Türhaltestange vielfach verstärken, was sich beim öffnen und Schließen der Fahrzeugtür außerordentlich unangenehm bemerkbar macht. Andererseits sind in der Lagerung der Türhaltestange von Kraftfahrzeugtürfeststellern sehr hohe radial wirkende und unangenehmerweise stoßartig auftretende Kraftspitzen aufzunehmen, die daraus resultieren, daß bei den gebräuchlichen Türfeststellern die für das Abbremsen und Festhalten der Tür in bestimmten vorgesehenen Öffnungslagen erforderlichen hohen Brems- und Haltekräfte in der Weise aufgebracht werden, daß eine mit Rastmarken versehene Türhaltestange durch ein mit federbelasteten Brems-und Haltekörpern versehenes Halterhäuse hindurchbewegt wird. Die beim Durchgang der Rastmarken der Türhaltestange zwischen den Bremskörpern mehr oder minder stoßartig entstehenden hohen Brems-und Haltekräfte müssen aber als radial zu dieser gerichtete Kräfte in der Lagerung der Türhaltestange aufgefangen bzw. abgestützt werden. Um auch unter diesen Betriebsbedingungen eine über eine lange Betriebszeit hin wartungs-und geräuschfrei arbeitende Lagerung der Türhaltestange des Türfeststeller zu erhalten wurden daher Lagerbuchsen aus wartungsfreiem Lagermaterial eingesetzt, über welche der die Türhaltestange am Lagerbock abstützende Lagerstift in der Scharnieraugenbohrung der Türhaltestange gelagert ist. Insbesondere resultierend aus der Tatsache, daß die Tür stets in gleichen, durch die Auslegung des Türfeststellers vorgezeichneten öffnungslagen abgebremst und festgehalten werden muß, treten die höchsten radialen Lagerbelastungen über die gesamte Lebensdauer des Türfeststellers hin immer an den gleichen Umfangsbereichen der Lagerung auf, was zu einem Ausschlagen der Lagerung bzw. zur Bildung von Rattermarken führt, die dann ihrerseits eine Geräuschentwicklung in der Lagerung der Türhaltestange bewirken. Diese Geräuschentwicklung kann durch besondere Maßnahmen in der Lagerausbildung, insbesondere eine ständige selbsttätige axiale Lagernachstellung, wie sie z. B. nach der EP-A-299 147 bei fliegender Lagerung der Türhaltestange durch die Anwendung in axialer Richtung wirkender Belastungsfedern in Verbindung mit einer konischen Ausbildung wenigstens eines Teiles des Lagerstiftes zwar verringert, aber nicht grundsätzlich beseitigt werden.When storing the door support rods of motor vehicle door locks, a particular problem arises from the fact that the adjacent body parts, door and door pillar are each hollow bodies, which, acting as a resonance body, also amplify the slightest noise in the storage of the door support rod, which increases when the vehicle door is opened and closed extremely unpleasantly noticeable. On the other hand, very high radially acting and unpleasantly jerky force peaks are to be taken up in the storage of the door holding rod of motor vehicle door locks, which result from the fact that in the conventional door locks the high braking and holding forces required for braking and holding the door in certain intended opening positions in the manner be applied that a door holding rod provided with detent marks is moved through a holder housing provided with spring-loaded braking and holding bodies. The high braking and holding forces that occur more or less abruptly during the passage of the latching marks of the door holding rod between the brake bodies must, however, be absorbed or supported as forces directed radially to this in the bearing of the door holding rod. In order to have one over a For a long period of operation, maintenance-free and noise-free storage of the door holding rod of the door arrester was used to obtain bearing bushes made of maintenance-free bearing material, via which the bearing pin supporting the door holding rod on the bearing block is mounted in the hinge eye bore of the door holding rod. In particular, as a result of the fact that the door must always be braked and held in the same opening positions as specified by the design of the door lock, the highest radial bearing loads always occur at the same circumferential areas of the bearing over the entire service life of the door lock, which leads to a Knocking out the storage or the formation of chatter marks, which in turn cause noise in the storage of the door handle. This noise can be caused by special measures in the camp training, in particular a constant automatic axial bearing adjustment, as z. B. according to EP-A-299 147 with flying storage of the door support rod by the application in the axial direction acting load springs in conjunction with a conical configuration of at least a part of the bearing pin although reduced, but not generally eliminated.
Es ist auch schon vorgesehen worden den Lagerstift einer Haltestangelagerung für Kraftwagentürfeststeller, vor allem durch Verwendung einer Spannhülse als Lagerstift, in sich federnd zu gestalten, um die Auswirkung der radial gerichteten Kraftspitzen innerhalb der Lagerung zu vermindern. Jedoch ist eine solche Gestaltung der Lagerung der Turhaltestange zum einen nur dort möglich, wo der Lagerstift in einem zweiarmigen Lagerbock beidseitig abgestützt ist und zum anderen mit der Gefahr behaftet, daß der Lagerstift in axialer Richtung zu wandern beginnt und damit die Lagerung nach einer längeren Betriebszeit des Türfeststellers unzuverlässig wird.It has also been provided to make the bearing pin of a support rod mounting for motor vehicle door locks, in particular by using an adapter sleeve as a bearing pin, resilient in order to reduce the effect of the radially directed force peaks within the bearing. However, such a design of the storage of the door retaining rod is only possible on the one hand where the bearing pin is supported on both sides in a two-armed bearing block and on the other hand carries the risk that the bearing pin begins to move in the axial direction and thus the storage after a longer operating time of the door arrester becomes unreliable.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde eine Haltestangenlagerung für Kraftwagentürfeststeller zu schaffen, die einerseits mit einem geringstmöglichen Aufwand herstellbar und montierbar ist und die andererseits ohne Verringerung der Festigkeit der Lagerung eine dauerhaft leichtgängige und insbesondere unter dem Angriff von radial zur Lagerachse gerichteten Kraftspitzen absolut geraüschfrei arbeitende Lagerung der Türhaltestange eines Kraftwagentürfeststellers gewährleistet.Based on this prior art, the invention has for its object to provide a handrail mounting for motor vehicle door locks, the one with the lowest possible Effort can be produced and assembled and, on the other hand, ensures that the door holding rod of a motor vehicle door arrester is supported without any reduction in the strength of the bearing, so that it can move smoothly over the long term and, in particular under the attack of force peaks directed radially to the bearing axis, it operates absolutely silently.
Diese Aufgabe wird bei der Haltestangenlagerung für einen Kraftwagentürfeststeller erfindungsgemäß dadurch gelöst, daß diejenige Scharnieraugenbohrung, in der der Lagerstift Laufsitz hat, diesem gegenüber ein Übermaß aufweist und der Lagerstift in dieser Scharnieraugenbohrung über eine Anzahl achsparallel ausgerichteter Blattfedern abgestützt ist. Der Lagerstift ist dabei zweckmäßigerweise in der ein Übermaß aufweisenden Scharnieraugenbohrung der Türhaltestange und dort über wenigstens eine, vorzugweise aber drei symetrisch angeordnete Blattfedern abgestützt, derart, daß zwei benachbarte Blattfedern beiderseists der Längsachse der Türhaltestange liegen.This object is achieved according to the invention in the support rod mounting for a motor vehicle door arrester in that the hinge eye bore in which the bearing pin has a seat has an excess compared to it and the bearing pin is supported in this hinge eye bore by a number of axially parallel leaf springs. The bearing pin is expediently supported in the oversized hinge eye bore of the door holding rod and there at least one, but preferably three symmetrically arranged leaf springs, such that two adjacent leaf springs are on both sides of the longitudinal axis of the door holding rod.
Die den Lagerstift in der Scharnieraugenbohrung abstützenden Blattfedern sind bei einer ersten bevorzugten Ausführungsform quer zur Bohrungsachse der Scharnieraugenbohrung nach innen gewölbt und ferner sind hierbei den Blattfedern achsparallel zur Lagerachse gerichtete radiale Nutausnehmungen in der Umfangswandung der Scharnieraugenbohrung zugeordnet, die einerseits eine Führung für die Blattfedern bilden, diesen aber andererseits beim Auftreten von radialen Spitzenbelastungen der Lagerung auch eine ausreichende Ausweichmöglichkeit bieten, derart, daß die Türhaltestange in ihrem unbelastetem Zustand vermittels der Blattfedern streifenförmig oder linienförmig und spielausgleichend elastisch, insbesondere aber außerhalb unmittelbarer Berührung mit diesem am Lagerstift abgestützt bzw. gelagert ist, wobei jedoch die freie Drehbarkeit der Türhaltestange gegenüber dem Lagerstift vollkommen und leichtgängig erhalten bleibt. Beim Auftreten zunehmender Längskrafte in der Türhaltestange werden die Blattfedern zunehmend verformt und tauchen daher zunehmend in die radialen Nutaunehmungen in der Umfangswandung der Scharnieraugenbohrung ein, bis die Umfangswandung der Scharnieraugenbohrung der Türhaltestange schließlich beim Auftreten von radial zur Lagerung gerichteten Kraftspitzen am Lagerstift zur Anlage kommt und damit die größten auftretenden Krafte durch unmittelbare flächige Anlage des Lagerstiftes an der Umfangswandung der Scharnieraugenbohrung der Türhaltestange übertragen werden. Dadurch können einerseits sehr hohe Lagerkräfte übertragen werden und erfolgt andererseits das Anlegen des Lagerstiftes an die Umfangswandung der Scharnieraugenbohrung derart gedämpft, daß die Entstehung von Geräuschen ausgeschlossen ist. Da die unbelastete Türhaltestange ferner lediglich über die Blattfedern am Lagerstift abgestützt ist können auch bei unbelasteter Türhaltestange in der Lagerung keine Geräusche entstehen, selbst wenn sich nach langer Betriebszeit des Türfeststellers eine gewisse Auslaibung der Scharnieraugenbohrung der Türhaltestange ergeben sollte. In diesem Zusammenhang ist hervorzuheben, daß über den Umfang der Scharnieraugenbohrung in der Türhaltestange hin gesehen die Anordnung der Blattfedern so getroffen ist, daß sie außerhalb derjenigen Umfangsbereiche der Scharnieraugenbohrung liegen, die beim Auftreten von Kraftspitzen mit dem Lagerstift in unmittelbare Anlage kommen.In a first preferred embodiment, the leaf springs supporting the bearing pin in the hinge eye bore are arched inwards transversely to the bore axis of the hinge eye bore, and furthermore radial groove recesses in the peripheral wall of the hinge eye bore, which are directed axially parallel to the bearing axis, are assigned to them, which on the one hand form a guide for the leaf springs, on the other hand, they also offer a sufficient escape option when radial peak loads occur in the bearing, such that the door retaining bar is supported or mounted in strips or lines in the unloaded state by means of the leaf springs and in an elastic manner to compensate for play, but especially outside direct contact with the latter on the bearing pin, however, the free rotatability of the door support rod relative to the bearing pin is completely and smoothly maintained. When increasing longitudinal forces occur in the door support rod, the leaf springs are increasingly deformed and therefore increasingly dive into the radial groove recesses in the circumferential wall of the hinge eye bore until the circumferential wall of the hinge eye bore of the door holding rod finally comes into contact with the occurrence of force peaks directed radially toward the bearing on the bearing pin and thus the greatest forces occurring due to the direct, flat contact of the bearing pin with the Circumferential wall of the hinge eye bore of the door support rod are transferred. As a result, very high bearing forces can be transmitted on the one hand, and on the other hand the bearing pin is applied to the peripheral wall of the hinge eye bore in such a way that noise is prevented. Since the unloaded door support rod is also only supported by the leaf springs on the bearing pin, no noise can occur in the storage even when the door support rod is unloaded, even if the door hinge eye bore shows a certain amount of wear after a long period of operation. In this context, it should be emphasized that over the circumference of the hinge eye bore in the door holding rod, the arrangement of the leaf springs is such that they lie outside those peripheral regions of the hinge eye bore that come into direct contact with the bearing pin when force peaks occur.
In einer besonders vorteilhaften Gestaltungsform ist hierbei weiterhin vorgesehen, daß die Bogenhöhe der quer zur Lagerachse gerichteten Wölbung der Blattfedern im entspannten Zustand der Summe aus der Tiefe der Nutausnehmungen in der Umfangswandung der Scharnieraugenbohrung und dessen Übermaße der Scharnieraugenbohrung der Türhaltestange gegenüber dem Lagerstiftdurchmesser entspricht. Dabei ist die Vorderkante der Blattfeder durch Einschneiden in der Nut oder durch Anlage auf dem Lagerbock festgesetzt.In a particularly advantageous embodiment, it is further provided that the arc height of the curvature of the leaf springs directed transversely to the bearing axis corresponds in the relaxed state to the sum of the depth of the groove recesses in the peripheral wall of the hinge eye bore and its oversize of the hinge eye bore of the door retaining rod compared to the bearing pin diameter. The front edge of the leaf spring is fixed by cutting into the groove or by resting on the pedestal.
Eine besonders einfache und damit preisgünstige Herstellungsweise der Blattfedern, die zugleich eine besonders einfache und zeitsparende Montage derselben gewährleistet kennzeichnet sich dadurch, daß die Blattfedern einteilig mit einer im wesentlichen glattflächigen und parallel zur Türhaltestangenbreitseite ausgerichtet anzuordnenden Halteplatte ausgebildet sind, wobei die Blattfedern durch Freischnitte an einem glattflächigen Federstahl-Blechzuschnitt gebildet sind. Die die Blattfedern bildenden Freischnitte des Blechzuschnittes können dabei in einer ersten Gestaltungsform innerhalb des sich mit der Scharnieraugenbohrung der Türhaltestange überdeckenden Bereiches der Halteplatte oder aber bei einer zweiten Gestaltungsform auch sich vom Umfang der Halteplatte aus etwa sternförmig radial nach außen erstreckend vorgesehen sein.A particularly simple and therefore inexpensive method of manufacturing the leaf springs, which at the same time ensures a particularly simple and time-saving assembly of the same is characterized in that the leaf springs are formed in one piece with an essentially smooth-faced and parallel to the door holding rod broad side to be arranged holding plate, the leaf springs being formed by free cuts on a smooth-faced spring steel sheet blank. The cutouts of the sheet metal blank that form the leaf springs can be provided in a first design within the area of the holding plate that overlaps with the hinge eye bore of the door holding rod, or in a second design also extend radially outward from the periphery of the holding plate in an approximately star shape.
Die mit der Halteplatte einteilige Ausbildung der Blattfedern ermöglicht zunächst eine höchst einfache Herstellung und Montage der Lagerung, da die durch die Halteplatte in vorgegebener Lage fixierten Blattfedern einfach in die Scharnieraugenbohrung der Türhaltestange eingesteckt werden können. Zum anderen ermöglicht die mit der Halteplatte einteilige Ausbildung der Blattfedern aber in einfacher Weise gleichzeitig auch die Ausbildung und Montage einer in Richtung der Lagerachse gerichteten Federabstützung der Türhaltestange am Lagerbock, insbesondere dadurch, daß bei einer ersten Verwirklichungsform vorgesehen ist, daß die Länge der Blattfedern annähernd der Materialdicke der Türhaltestange entspricht und die Blattfedern über eine senkrecht zur Ebene der Türhaltestangenbreitseite und dieser gegenüber nach außen gerichtete Ausbiegung an die Halteplatte anschließen bzw. daß andere Ausbiegungen ohne Blattfedern in die Halteplatte eingeformt sind. Diese senkrecht zur Breitseite der Türhaltestange gerichtete Ausbiegung der Blattfedern bildet eine in Richtung der Lagerachse gerichtete federnde Abstützung der Türhaltestange am Lagerbock bzw. an einem Kopf des Lagerstiftes, ohne daß hierfür zusätzliche Teile oder zusätzliche Montagevorgänge erforderlich wären. Insbesondere kann diese Ausbiegung der Blattfedern in einem Arbeitsgang mit der Herstellung der mit den Blattfedern einteilig ausgebildeten Halteplatte ausgeformt werden.The one-piece design of the leaf springs with the holding plate initially enables extremely simple manufacture and assembly of the bearing, since the leaf springs fixed in a predetermined position by the holding plate can simply be inserted into the hinge eye bore in the door holding rod. On the other hand, the one-piece design of the leaf springs with the holding plate also enables, in a simple manner, the formation and assembly of a spring support of the door holding rod on the bearing bracket, which is directed in the direction of the bearing axis, in particular in that, in a first embodiment, the length of the leaf springs is approximately the same corresponds to the material thickness of the door holding rod and the leaf springs connect to the holding plate via a bend perpendicular to the plane of the broad side of the door holding rod and opposite to this, or that other bends are formed into the holding plate without leaf springs. This bend of the leaf springs directed perpendicular to the broad side of the door holding rod forms a resilient support of the door holding rod directed in the direction of the bearing axis on the bearing block or on a head of the bearing pin, without additional parts or additional assembly processes being required for this. In particular, this deflection of the leaf springs can be formed in one operation with the production of the holding plate formed in one piece with the leaf springs.
Eine federnde Abstützung der Türhaltestange in Richtung der Lagerachse kann bei einer Gestaltungsform, bei welcher die Blattfedern zusammen mit einer Halteplatte durch einen sternförmigen Zunschnitt aus Federstalblech gebildet sind dadurch erreicht werden, daß die die Blattfedern bildenden Freischnitte parallel zur Halteplatte nach innen zur Scharnieraugenbohrung hin umgebogen und schließlich parallel zur Scharnieraugenbohrung abgewinkelt sind.A resilient support of the door holding rod in the direction of the bearing axis can be achieved in a design in which the leaf springs together with a holding plate are formed by a star-shaped cut from spring steel sheet in that the free cuts forming the leaf springs are bent parallel to the holding plate and inwards towards the hinge eye bore and are finally angled parallel to the hinge eye bore.
Nach einer anderen Ausgestaltungsform kann, ohne daß sich eine Änderung der Wirkungsweise der Lagerung der Türhaltestange über Blattfedern oder eine Erhöhung des Herstellungs-oder Montageaufwandes für die Lagerung ergibt, aber auch vorgesehen sein, daß die Blattfedern um zur Lagerachse parallele Achsen gewölbt sind und die ihnen zugeordneten radialen Nutausnehmungen in der Umfangswandung der Scharnieraugenbohrung der Türhaltestange der Breite der Blattfedern gegenüber ein Übermaß aufweisen. Das Maß der Bogenhöhe der Wölbung der Blattfedern entspricht hierbei gleichfalls der Summe aus der Tiefe der Nutausnehmungen in der Umfangswandung der Scharnieraugenbohrung und der Hälfte deren Übermaßes gegenüber dem Lagerstift.According to another embodiment, it can be provided that the leaf springs are curved around axes parallel to the bearing axis and that they do not result in a change in the mode of operation of the mounting of the door holding rod via leaf springs or an increase in the manufacturing or assembly expenditure for the bearing assigned radial groove recesses in the peripheral wall of the hinge eye bore of the door retaining rod have an excess of the width of the leaf springs. The dimension of the arch height of the curvature of the leaf springs also corresponds to the sum of the depth of the groove recesses in the circumferential wall of the hinge eye bore and half of their excess compared to the bearing pin.
Gemäß einer weiteren Einzelausgestaltung kann ferner noch vorgesehen sein, daß die Blattfedern doppellagig ausgebildet sind und einen im wesentlichen glattflächig ebenen Träger und ein um eine zur Lagerachse parallele Achse gewölbtes Federteil aufweisen, wobei die Blattfedern jeweils aus einem eine im wesentlichen rechteckige Grundrißform aufweisenden Freischnitt gebildet sind, wobei das freie Ende des Freischnittes unter Wölbung um eine zur Lagerachse parallele Achse gegen den glattflächig belassenen Verbindungsbereich des Freischnittes mit der Halteplatte zurückgebogen ist.According to a further individual embodiment, it can further be provided that the leaf springs are double-layered and have a substantially smooth, flat support and a spring part curved around an axis parallel to the bearing axis, the leaf springs each being formed from a free cut having an essentially rectangular outline shape , wherein the free end of the free cut is bent back with a curvature about an axis parallel to the bearing axis against the smoothly left connection area of the free cut with the holding plate.
