Abstract

The bearing, which is manufactured from a flexible plastic, has a yoke (13) attached to a frame (22) and having a holding shell (12) and a supporting shell (19), which is connected in a radially flexible manner to the yoke (13) by two film hinges (20) and is supported on the frame (22). Two pegs (18) of the yoke (13) are guided in openings (25) in the frame (22). The radial flexibility of the bearing allows assembly and disassembly of the ball pivot (11) and the integral nature of the bearing simplifies its manufacture and installation as well as stock-holding. <IMAGE>

Description

Stand der TechnikState of the art

Die Erfindung betrifft ein Lager für Kugelzapfen nach der Gattung des Anspruchs 1. Die Zweiteiligkeit des La­ gers ist deshalb erforderlich, damit bei der Montage und Demontage des Lagerzapfens die Stützschale ge­ genüber der Halteschale in radialer Richtung bewegbar ist. Diese Zweiteiligkeit des Lagers ist in fast jeder Hinsicht nachteilig wegen zweier Fertigungswerkzeuge und zweier Montagevorgänge sowie der aufwendigeren La­ gerhaltung. Diese Nachteile sind insbesondere in der Groß­ serienfertigung von Fahrzeug-Scheinwerfern problematisch und zu vermeiden.The invention relates to a bearing for ball pins according to the genus of claim 1. The two-part of La gers is therefore necessary so that during assembly and disassembly of the trunnion ge the support shell movable in the radial direction relative to the holding shell is. This two-part camp is in almost everyone In terms of disadvantage because of two manufacturing tools and two assembly processes as well as the more complex La maintenance. These disadvantages are particularly large Series production of vehicle headlights problematic and avoid.

Vorteile der ErfindungAdvantages of the invention

Mit der Erfindung wird das im vorerwähnten Stand der Tech­ nik dargelegte Problem mit technisch einfachen Mitteln ge­ löst.With the invention that is in the aforementioned Tech nik problem with technically simple means ge solves.

Der Erfindung liegt der Gedanke zugrunde, die bei­ den Lagerschalen als ein Stück herzustellen und deren gegenseitige Radialelastizität durch zwei sogenannte Filmscharniere zu erreichen. Durch die Einstückigkeit des Lagers wird nur ein Fertigungswerkzeug benötigt und es ist nur ein Montagevorgang erforderlich; außerdem ver­ einfacht sich die Lagerhaltung.The invention is based on the idea that to manufacture the bearing shells as one piece and their mutual radial elasticity through two so-called Reach film hinges. Through the one-piece  of the warehouse, only one production tool is required and only one assembly process is required; also ver warehousing is simplified.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben. Mit Anspruch 5 wird das Auf­ stecken des Lagers auf das Gestell ohne Sichtkontrolle erreicht und das Lager für das anschließende Befestigen durch Schrauben am Gestell gesichert.Advantageous developments of the invention are in the Subclaims described. With claim 5 is the on put the bearing on the frame without visual inspection reached and the camp for subsequent fastening secured to the frame by screws.

Beschreibung des AusführungsbeispielesDescription of the embodiment

Ein einstückiges Lager aus elastischem Kunststoff nimmt einen Kugelzapfen 11 auf und ist bezüglich einer Ebene 9 im wesentlichen symmetrisch. Das Lager hat einen form­ steifen Bügel 13 mit einer sphärischen Halteschale 12 und zwei Augen 14 mit je einem Durchgangsloch 15. Zwischen bei­ den Augen 14 und der Halteschale 12 sind je ein Steg 17 mit jeweils einer Versteifungsrippe 16 angeordnet.A one-piece bearing made of elastic plastic receives a ball pin 11 and is essentially symmetrical with respect to a plane 9 . The bearing has a stiff bracket 13 with a spherical holding shell 12 and two eyes 14 , each with a through hole 15 . A web 17 , each with a stiffening rib 16, is arranged between the eyes 14 and the holding shell 12 .

An der durch die Versteifungsrippe 16 und den Steg 17 ge­ bildeten Kante ist ein Zapfen 18 entgegengesetzt der Halteschale 12 angeordnet, wobei beide Zapfen 18 zu­ einander parallel sind. Eine ebenfalls sphärische Stütz­ schale 19 ist an ihren beiden Endstücken durch je ein im Querschnitt S-förmiges Filmscharnier 20 (Band) einstückig mit dem Bügel 13 verbunden. Beide Filmscharniere 20 er­ möglichen eine gegenseitige radial elastische Bewegung beider Schalen 12, 19 gemäß Doppelpfeil 21, die für die Montage und Demontage des Kugelzapfens 11 erforderlich ist.On the edge formed by the stiffening rib 16 and the web 17 , a pin 18 is arranged opposite the holding shell 12 , both pins 18 being parallel to one another. A likewise spherical support shell 19 is integrally connected to the bracket 13 at its two end pieces by a film hinge 20 (band) which is S-shaped in cross section. Both film hinges 20 he possible a mutual radial elastic movement of the two shells 12 , 19 according to double arrow 21 , which is required for the assembly and disassembly of the ball pin 11 .

Ein aus Kunststoff hergestelltes, nur abschnittsweise dar­ gestelltes Gestell 22 (Rahmen für Kraftfahrzeug-Schein­ werfer) hat eine Platte 23 und zwei durch jeweils zwei Rippen 24 gebildete Durchbrüche 25 (von denen nur einer dargestellt ist) sowie eine sphärische Aufnahme 26. Das in seiner Funktionslage dargestellte Lager mit dem Kugel­ zapfen 11 liegt mit beiden Augen 14 auf der Platte 23 auf, und die beiden Zapfen 18 sind in den Durchbrüchen 25 eingeschoben. Dabei liegt die Stützschale 19 an der Aufnahme 26 an, und die Halteschale 12 drückt den Kugel­ zapfen 11 an die Stützschale 19. Das Lager wird mittels zweier (nicht dargestellt) Schrauben am Gestell 22 be­ festigt.A made of plastic, only partially presented frame 22 (frame for motor vehicle headlights) has a plate 23 and two openings 25 formed by two ribs 24 (only one of which is shown) and a spherical receptacle 26th The bearing shown in its functional position with the ball pin 11 lies with both eyes 14 on the plate 23 , and the two pins 18 are inserted into the openings 25 . The support shell 19 rests on the receptacle 26 , and the holding shell 12 presses the ball pin 11 onto the support shell 19 . The camp is fastened by means of two (not shown) screws on the frame 22 be.
