Description

Die Erfindung betrifft einen mit einem aushängbaren Türscharnier baulich vereinigten Türfeststeller für Kraftwagentüren, nach der Präambel des Patentanspruchs 1.The invention relates to a with a detachable door hinge structurally combined door arrester for motor vehicle doors, according to the preamble of the Claim 1.

Die DE-A-29700043 beschreibteinen mit einem Türscharnier baulich vereinigten Türfeststeller, bei dem die Brems-und Haltekörper als auf wenigstens einer quer zur Scharnierachse ausgerichteten Lagerachse rotierbar aufgenommene Wälzkörper ausgebildet sind, und die Brems-und Haltekörper unter Belastung durch eine gegen das freie Ende des Scharnierstiftes abgestützten Belastungsfeder mit den als Vertiefungen in einer an der Stirnseite eines aufragenden als wenigstens teilringförmige, konzentrisch zur Achse des Scharnierstiftes angeordneten Kragens ausgebildeten Laufbahn vorgesehenen Rastmarken zusammenwirken. Charakteristischerweise sind bei diesem Vorschlag clie als Kegelrollen ausgebildeten Brems-und Haltekörper an einem durch ein Metallteil gebildeten Bremskörperträger gelagert, an welchem zugleich auch die zur Auforingung der erforderlichen Brems-und Haltekräfte erforderliche Federlast angreift und welcher im weiteren eine drehsichere Verbindung zum Scharnierstift beinhaltet. Insbesondere ist bei dieser Bauart auch eine mit einer axial gerichteten Stirnverzahnung des Bremskörperträgers in einem formschlüssigen drehsicheren Eingriff stehende Abstützung der Federlast gegen den Scharnierstift aus einem Metallteil gebildet.DE-A-29700043 describes a structurally combined with a door hinge Door stop, in which the braking and holding body than on at least one bearing axis aligned transversely to the hinge axis Rolling bodies are rotatably received, and the braking and Holding body under load against the free end of the hinge pin supported load spring with as recesses in one the end face of a towering as at least partially annular, concentric to the axis of the hinge pin arranged collar formed track the intended locking marks interact. Are characteristic of This proposal was followed by brake and holding bodies designed as tapered rollers a brake body bracket formed by a metal part, on which at the same time also that required to record the braking and holding forces required required spring load attacks and which furthermore a non-rotatable connection to the hinge pin included. In particular, this type is also one with an axially directed spline of the brake body carrier in a positive, non-rotatable engagement of the spring load against the hinge pin formed from a metal part.

Diese Gestaltungsform der Feststelleinrichtung eines Türfestastellers erfordert einen verhältnismäßig großen Aufwand im Zusammenhang mit der Lagerung der Kegelrollen vermittels eigener Lagerachsen an einem Bremskörperträger. Die Lagerung der Brems-und Haltekörper über eigene Achsen an einem Bremskörperträger bringt zudem eine zusätzliche Reibung und damit zusätzlichen Verschleiß innerhalb des Türfeststellers mit sich. Schließlich erfordert die bekannte Gestaltungsform des Türfeststellers nicht zuletzt infolge der Notwendigkeit einer wenigstens teilweisen Aufnahme der Brems-und Haltekörper im Bremskörperträger insgesamt auch noch einen verhältnismäßig großen Einbauraum für die Scharnier-Türfeststellereinheit. This design of the locking device a door lock plate requires a relatively large effort in connection with the storage of the tapered rollers by means of their own bearing axles a brake body carrier. The storage of the brake and holding body on its own Axles on a brake body carrier also bring additional friction and therefore additional wear within the door arrester. Finally, the known design of the door arrester does not require lastly due to the need for at least partial inclusion of the Braking and holding body in the brake body carrier as a whole is also relatively large installation space for the hinge door stay unit.

Die DE-A-86 27 459 zeigt einen mit einem aushängbaren Türscharnier baulich vereinigten Türfeststeller für Kraftwagentüren, bei dem eine obere, durch Tellerfeder belasteter, als Druckplatte bezeichneter Laufring auf Wälzkörper in Form von Kugeln drückt. Die Kugeln 12 sind in Öffnungen eines Käfigs achslos gefesselt, der über ein Vielzahnprofil verdrehfest mit dem Scharnierbolzen verbunden ist. Desweiteren wirken die Kugeln als Brems- und Haltekörper, da sie beim Verschwenken der Tür in Vertiefungen des als Auge gestalteten unteren Scharnierteils federnd einrasten können.DE-A-86 27 459 shows a structurally with a detachable door hinge United door lock for motor vehicle doors, in which an upper, by Belleville spring loaded race, known as pressure plate, on rolling elements in Presses shape of balls. The balls 12 are axleless in openings in a cage tied, the torsion-proof with a hinge pin connected is. Furthermore, the balls act as braking and holding bodies, because when swiveling the door into recesses of the eye can snap the lower hinge part into place.

Während des Gebrauchs sind die Laufbahnen der Kugeln auf und die Vertiefungen in dem Scharnierteil 1 selbst bei Abdichtung und Schmierung einem gewissen Verschleiß unterworfen. Bei größerem Verschleiß wird eine ausreichende Feststellung der Tür nicht mehr erzielt, und das Scharnierteil muß komplett ausgewechselt werden. Die Vertiefungen müssen in einer Kreisbahn sorgfältig in das untere, unhandliche Scharnierteil eingebracht werden, was einen erheblichen Reparatur- bzw. Herstellungsaufwand bedeutet.During use, the raceways of the balls are open and open Wells in the hinge part 1 even with sealing and lubrication subject to a certain wear. With greater wear, a sufficient detection of the door is no longer achieved, and the hinge part be completely replaced. The depressions must be in a circular path carefully inserted into the lower, bulky hinge part what means a considerable repair or manufacturing effort.

DE-A-89 04 337 zeigt ebenfalls einen mit einem aushängbaren Türscharnier baulich vereinigten Türfeststeller, bei dem ein oberer Laufring als Drucklager ausgebildet ist. Das Drucklager drückt Kugeln, die in einem Käfig achslos geführt sind, federnd in Vertiefungen, die in einer unteren Bundhülse eingebracht sind.DE-A-89 04 337 also shows one with a detachable door hinge structurally combined door lock, in which an upper race as a thrust bearing is trained. The thrust bearing presses balls that are axleless in a cage are guided, resilient in recesses in a lower collar are introduced.

Die Bundhülse dient auch als Lagerbuchse für den Scharnierbolzen und muß unter Preßpassung genau in den oberen Scharnierteil, dem Türteil, eingepreßt werden. Bei Verschleiß der Vertiefungen ist die eingepreßte Bundhülse umständlich auszubauen und durch eine neue, infolge genauer Paßmaße relativ teuere Bundhülse zu ersetzen The collar sleeve also serves as a bearing bush for the hinge pin and must press-fit exactly into the upper hinge part, the door part become. If the recesses wear out, the collar sleeve is pressed in cumbersome to expand and with a new, due to exact fit dimensions relatively expensive collar sleeve to replace

Es ist Aufgabe der Erfindung, einen mit einem aushängbaren Türscharnier baulich vereinigten Türfeststeller für Kraftwagentüren zu schaffen, der bei möglichst geringem Herstellungs- bzw. Reparaturaufwand eine exakte Feststellung der Tür in den jeweiligen Brems- und Haltestellungen gewährleistet.It is an object of the invention, one with a detachable door hinge structurally combined door arrester for motor vehicle doors to create the the lowest possible manufacturing or repair effort an exact Locking the door in the respective braking and stopping positions guaranteed.

Diese Aufgabe wird bei dem eingangs genannten Türfeststeller erfindungsgemäß mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst. This task is performed with the door arrester mentioned at the beginning According to the invention with the characterizing features of claim 1 solved.

Der Erfindung schalft einen mit einem aushängbaren Türscharnier baulich vereinigten Türfeststeller für Kraftwagentüren der eingangs bezeichneten Bauart, der unter Gewährleistung einer exakten Feststellung der Türe in den jeweils vorbestimmten Brems-und Haltestellungen bei möglichst geringem Herstellungsaufwand eine kleinbauende, wenig Embauraum beanspruchende sowie gewichtsoptimierte Form des Feststellers und weitgehend unabhängig von Toleranzen ein reibungsarmer, geräuschloser Gang des Türfeststellers einer Scharnier-Feststellereinheit erreicht ist.The invention scarfs one with a detachable Door hinge structurally combined door arrester for motor vehicle doors the type described at the beginning, which is under warranty an exact determination of the door in the predetermined Braking and stopping positions with the least possible manufacturing effort small-sized, space-saving and weight-optimized Shape of the lock and largely independent of tolerances a low-friction, noiseless movement of the door arrester of a hinge arrester unit is reached.

Dem Prinzip der Erfindung entsprechend sind einzelne. voneinander unabhängig jeweils mit einer Bremsrampe oder einer Gruppe von Bremsrampen zusammenwirkende, als Wälzkörper ausgebildete Brems-und Haltekörper in Ausnehmungen eines durch einen Flachmaterialzuschnitt gebildeten Käfigs senkrecht zu dessen Ebene verstellbar aufgenommen, derart. daß sie infolge einer Relativdrehung zwischen Käfig und Halteeinrichtung unter Aufbringung der erforderlichen Brems-bzw. Haltekräfte entgegen einer Federbelastung höhenverstellbar sind. Der baulichen Einfachheit halber sind die Brems-und Haltekörper zweckmäßigerweise durch eine gemeinsame Belastungsfeder beaufschlagt. Aus dem erfindungsgemäßen Prinzip resultiert zunächst eine erhebliche Verringerung des für die Herstellung der Feststelleinrichtung erforderlichen Aufwandes, da der Verzicht auf den Einsatz eines Bremskörperträgers nicht nur den für dessen Herstellung sondern auch den für die Lagerung der Brems-bzw. Haltekörper über besondere Lagerachsen erforderlichen Aufwand ausschließt. Abgesehen von der Verringerung des erforderlichen Herstellungsund Zusammenbauaufwandes bringt die erfindungsgemäße achsfreie Anordnung der die Brems-und Haltekörper bildenden Wälzkörper auch eine beträchtliche Verringerung der innerhalb der Feststelleinrichtung entstehenden Reibung und damit auch des entstehenden Verschleißes mit sich. Andererseits gewährleistet auch der Einsatz einzelner voneinander unabhängig mit Bremsrampen einer Halteeinrichtung zusammenwirkender Brems-und Haltekörper bildender Wälzkörper eine exakte Einhaltung vorgegebener Halte-und Feststellpunkte der Türe.
Zugleich eröffnet der Verzicht auf einen die Brems-und Haltekörper lagernden Bremskörperträger eine weitere Möglichkeit zur Verringerung der Baugröße und damit des erforderlichen Einbauraumes für den Türfeststeller bzw. die Scharnier-Feststellereinheit.
Individuals are in accordance with the principle of the invention. Independently from one another, each with a braking ramp or a group of braking ramps, designed as rolling bodies, braking and holding bodies, accommodated in recesses in a cage formed by a flat material blank, so as to be adjustable perpendicular to its plane, such. that they are due to a relative rotation between the cage and the holding device with the application of the required braking or. Holding forces are adjustable in height against a spring load. For structural simplicity, the brake and holding bodies are expediently acted upon by a common loading spring. The principle according to the invention initially results in a considerable reduction in the expenditure required for the manufacture of the locking device, since the omission of the use of a brake body carrier not only for the manufacture of the latter, but also for the storage of the brake or. Holders over special bearing axles excludes necessary effort. In addition to the reduction in the manufacturing and assembly effort required, the axis-free arrangement of the rolling bodies forming the braking and holding bodies according to the invention also results in a considerable reduction in the friction occurring within the locking device and thus also in the wear that occurs. On the other hand, the use of individual rolling bodies forming brake bodies and holding bodies interacting independently of one another with braking ramps of a holding device also ensures exact adherence to predetermined stopping and locking points of the door.
At the same time, the omission of a brake body support supporting the brake and holding bodies opens up a further possibility for reducing the structural size and thus the required installation space for the door arrester or the hinge arrester unit.

Bei einer derartigen Anordnung ist der glattflächige Laufring zweckmäßigerweise vermittels eines Wälzlagers gegen die außenliegende Gewerbefläche der einen Scharnierhälfte abgestützt. In Verbindung mit einem formschlüssig aber axial unverschieblich mit dem Scharnierstift gekoppelten. die die Brems-und Haltekörper bildenden Wälzkörper fesselnden Käfig kann der die Halteeinrichtung bildende Laufring dann durch einen mit einer Federlast beaufschlagten Druckring gebildet sein, wobei der die Halteeinrichtung tragende Druckring ferner gemäß einer besonderen Ausgestaltungsform vermittels Gleitführungen bildender Wälzkörper axial verschiebbar aber drehsicher mit dem an der Scharnierhälfte festgelegten Gehäuse gekoppelt ist.In a preferred embodiment of an inventive It is provided that the cage is essentially plate-shaped designed and by means of an inner peripheral toothing of a central recess non-rotatably connected to the hinge pin and that with locking marks provided holding device against rotation on that hinge half, in which this run seat has. is set.
