Description

Die Erfindung betrifft einen Scheinwerfer für Fahrzeuge mit einem gegossenen schalenförmigen Reflektor, der einen inneren und äußeren Brennort aufweist, mit einer zwischen einer Linse und dem Reflektor angeordneten Blendenwelle, die um eine horizontale und quer zur optischen Achse verlaufenden Drehachse in mehrere Drehstellungen für unterschiedliche Lichtfunktionen verstellbar ist, und mit einem an dem vorderen Randbereich des Reflektors befestigten Halter für mindestens ein Lagerungsmittel der Blendenwelle.The invention relates to a headlamp for vehicles with a cast cup-shaped reflector having an inner and outer focal point, with a diaphragm shaft arranged between a lens and the reflector, the axis of rotation about a horizontal and transverse to the optical axis is adjustable in several rotational positions for different light functions, and with a holder attached to the front edge portion of the reflector for at least one storage means of the diaphragm shaft.

Aus der DE - A - 199 21 907 ist ein Scheinwerfer für Fahrzeuge mit einem zwei Brennorte aufweisenden schalenförmigen Reflektor bekannt, dem eine Linse und eine Blendenwelle zugeordnet sind. Die Blendenwelle erstreckt sich quer zur optischen Achse der im Scheitelbereich des Reflektors angeordneten Lichtquelle. Die Blendenwelle ist drehbar um ihre Drehachse gelagert und weist umlaufend eine nach außen gekrümmte Mantelfläche mit mehreren Brennlinien auf, die je nach Drehstellung der Blendenwelle zur Bildung von Hell-Dunkel-Grenzen unterschiedlicher Lichtfiguren dienen. Die Blendenwelle weist Brennlinien für symmetrisches und asymmetrisches Abblendlicht und Fernlicht auf. An den gegenüberliegenden Endbereichen der Blendenwelle ist ein Antriebsmittel bzw. Lagerungsmittel angeordnet, so dass die Blendenwelle in die vorgegebenen Drehstellungen positioniert und verstellt werden kann. Die Blendenwelle ist mit ihren Lagerungsmitteln an beiden Endbereichen in Lageröffnungen eines Halters gelagert, der an dem vorderen Randbereich des Reflektors befestigt ist. An dem Halter ist seitlich das mit der Blendenwelle gekoppelte Antriebsmittel befestigt. Das Antriebsmittel besteht aus einem Motor und einem Getriebe. Nachteilig hierbei ist, dass die Lage der Lagerung und somit der Blendenwelle ausschließlich durch den Halter festgelegt ist. Da dieser ein separates Teil ist kann die Toleranzkette zu der Reflexionsfläche des Reflektors so groß sein, dass die Blendenwelle nicht optimal zu der Reflexionsfläche positioniert ist und somit die unterhalb einer Hell-Dunkel-Grenze der abgeblendeten Lichtfiguren vorgeschrieben und gewünschten hohen Lichtwerte nicht mehr als ausreichend groß sind. Darüber hinaus kann durch eine ungenaue Lage der Blendenwelle zur Reflexionsfläche des Reflektors die Lichtfigur im Bereich der Hell-Dunkel-Grenze einen störenden Farbsaum aufweisen.From DE - A - 199 21 907 is a headlamp for vehicles with a two Known burner dish-shaped reflector, which is a lens and a diaphragm shaft are assigned. The aperture shaft extends transversely to the optical axis arranged in the apex region of the reflector Light source. The diaphragm shaft is rotatably supported about its axis of rotation and has encircling an outwardly curved lateral surface with several focal lines depending on the rotational position of the diaphragm shaft to the formation of light-dark boundaries serve different light figures. The aperture shaft points Burning lines for symmetrical and asymmetrical dipped beam and high beam on. At the opposite end portions of the shutter shaft is a Drive means or storage means arranged so that the diaphragm shaft in the predetermined rotational positions can be positioned and adjusted. The Aperture shaft is with its storage means at both end areas in Bearing openings of a holder mounted on the front edge of the area Reflector is attached. On the holder is the side with the aperture shaft coupled drive means attached. The drive means consists of a motor and a gearbox. The disadvantage here is that the location of storage and thus the diaphragm shaft is fixed exclusively by the holder. Because of this a separate part is can the tolerance chain to the reflection surface of the Reflectors should be so large that the aperture is not optimal to the Reflection surface is positioned and thus the below a cut-off line the dimmed light figures prescribed and desired high light values are not more than sufficiently large. In addition, can by an inaccurate position of the diaphragm shaft to the reflection surface of the Reflektors the light figure in the range of the light-dark border a disturbing Have color fringing.

Aus der DE - A - 100 47 207 ist ein Scheinwerfer für Fahrzeuge mit einer Blendenwelle bekannt, deren Verbindung mit dem vorderen Randbereich des Reflektors in der Anmeldung weder beschrieben noch klar dargestellt ist.From DE - A - 100 47 207 is a headlamp for vehicles with a Aperture shaft known to be connected to the front edge of the area Reflektors in the application neither described nor clearly illustrated.

Aufgabe der Erfindung ist es, den im Oberbegriff des Anspruchs 1 beschriebenen Scheinwerfer für Fahrzeuge derart zu verbessern, dass bei einem einfach aufgebauten Scheinwerfer nach der Montage der Blendenwelle ihre genaue Positionierung zur Reflexionsfläche des Reflektors sicher ist. Diese Aufgabe wird nach der Erfindung dadurch gelöst, dass der an dem vorderen Randbereich des Reflektors befestigte Halter mit einem Abschnitt eine Lagerschale des vorderen Randbereichs überspannt und das Lagerungsmittel der Blendenwelle radial zur Drehachse spielfrei in der Lagerschale haltert. Der gegossene Reflektor ist einteilig ausgeführt und mittels Druckgießen zum Beispiel aus einer Magnesium- oder Aluminiumlegierung oder mittels Spritzgießen aus Kunststoff herstellbar. Die Blendenwelle ist genau zur Reflexionsfläche des Reflektors positioniert, da die Lagerschale des Reflektors und seine Reflexionsfläche zusammen durch ein verstellbares Werkzeugteil entformbar sind und der Halter die Blendenwelle an der Lagerschale hält. Durch die genaue Positionierung der Blendenwelle zur Reflexionsfläche ist die Blendenwelle auch genau zum benachbarten äußeren Brennort des Reflektors angeordnet und werden unterhalb der Hell-Dunkel-Grenze der jeweils erzeugten Lichtfigur optimale Lichtwerte erreicht. Darüber hinaus entsteht wegen der genauen Positionierung der Blendenwelle zum äußeren Brennort des Reflektors kein störender Farbsaum an der Hell-Dunkel-Grenze der Lichtfigur.The object of the invention is the, in the preamble of claim 1 described headlights for vehicles to improve such that at a simply constructed headlight after the assembly of the diaphragm shaft their exact positioning to the reflection surface of the reflector is safe. These The object is achieved according to the invention in that the front Edge portion of the reflector fastened holder with a section one Bearing shell of the front edge area spans and the storage means the diaphragm shaft holds radially in the bearing shell without clearance radially to the axis of rotation. Of the cast reflector is made in one piece and diecasting for Example of a magnesium or aluminum alloy or by means Injection molding made of plastic. The aperture is exactly to Reflection surface of the reflector positioned as the bearing shell of the reflector and its reflection surface together by an adjustable tool part are demoldable and the holder holds the diaphragm shaft to the bearing shell. By the exact positioning of the diaphragm shaft to the reflection surface is the Aperture also exactly to the adjacent outer focal point of the reflector arranged and below the cut-off line of each generated light figure reaches optimal light levels. In addition, arises because of the exact positioning of the aperture shaft to the outer focal point the reflector no disturbing color fringing at the cut-off of the Light figure.

Nach einer Weiterbildung der Erfindung liegt der die Lagerschale des Reflektors überspannende Abschnitt des Halters unter Vorspannung an dem Lagerungsmittel der Blendenwelle an und drückt das Lagerungsmittel gegen die Lagerschale, wobei die Lagerschale des Reflektors eine Zweipunktanlage definierende Positionierungsflächen für das Lagerungsmittel der Blendenwelle aufweist und eine Anlageseite des die Lagerschale des Reflektors überspannenden Abschnitts des Halters zusammen mit den Positionierungsflächen der Lagerschale des Reflektors eine Dreipunktanlage für das Lagerungsmittel der Blendenwelle definiert. Dadurch ist die Blendenwelle sehr genau zum äußeren Brennort des elliptischen Reflektors angeordnet und sicher in allen Richtungen quer zur Drehachse spielfrei an der Lagerschale gehalten. In diesem Zusammenhang ist es vorteilhaft, wenn mindestens zu einer der beiden Positionierungsflächen der Zweipunktanlage eine das Lagerungsmittel parallel zur Drehachse fixierende Anlagefläche benachbart angeordnet ist. Es kann auch auf beiden Seiten der beiden Positionierungsflächen jeweils eine Anlagefläche angeordnet sein, die zusammen ein Nut bilden und das Lagerungsmittel der Blendenwelle zwischen sich aufnehmen.According to a development of the invention is the bearing shell of the reflector spanning portion of the holder under pretension on the Storing means of the diaphragm shaft and presses the storage means against the Bearing shell, wherein the bearing shell of the reflector a two-point system defining positioning surfaces for the storage means of the diaphragm shaft has and a plant side of the bearing shell of the reflector spanning section of the holder together with the Positioning surfaces of the bearing shell of the reflector a three-point system for defines the storage means of the diaphragm shaft. This is the aperture shaft arranged very precisely to the outer focal point of the elliptical reflector and safe in all directions transverse to the axis of rotation backlash on the bearing shell held. In this context, it is advantageous if at least to one of the two positioning surfaces of the two-point system a the Storage means adjacent to the axis of rotation fixing abutment surface adjacent is arranged. It can also be on both sides of the two Positioning surfaces are each arranged a contact surface, the together form a groove and the storage means of the diaphragm shaft between to record oneself.

Die Blendenwelle ist leichtgängig drehbar, wenn das Lagerungsmittel der Blendenwelle ein auf einen Lagerzapfen der Blendenwelle aufgesetztes Wälzlager aufweist.The diaphragm shaft is rotatable smoothly when the storage means of Aperture shaft placed on a journal of the diaphragm shaft Rolling bearing has.

Das Lagerungsmittel der Blendenwelle ist geschützt vor Beschädigung angeordnet und sicher gehalten ist, wenn der Halter eine Lagerschale bildet, die zusammen mit der Lagerschale des Reflektor eine Lageröffnung für das Lagerungsmittel der Blendenwelle ist und die Lagerschale des Halters ein radial nach innen gerichtetes und die Anlagefläche für die Dreipunktanlage aufweisendes Anlageelement aufweist. Der Halter kann kostengünstig aus einer Blechplatine ausgestanzt sein, wobei das Anlageelement ein aus dem Halter herausgebogener Blechabschnitt ist.The shielding means of the shutter shaft is protected against damage is arranged and securely held when the holder forms a bearing shell, the together with the bearing shell of the reflector, a bearing opening for the Storage means of the diaphragm shaft is and the bearing shell of the holder a radial inward and the contact surface for the three-point system having exhibiting contact element. The holder can cost-effectively from a Be punched sheet metal blank, wherein the contact element from the holder bent sheet metal section is.

Nach einer bevorzugten Ausführungsform ist die Blendenwelle mit einem Lagerungsmittel an einem freien Endabschnitt durch den Halter und die Lagerschale des Reflektors radial und axial gehaltert, während die Blendenwelle mit dem anderen freien Endabschnitt in einem am Reflektor gehalterten Antriebsmittel der Blendenwelle radial zur Drehachse gehaltert und axial schwimmend gelagert ist. Dadurch können zwischen der Blendenwelle und dem Antriebsmittel keine Verspannungen auftreten. Die Blendenwelle ist durch das Antriebsmittel genau zum äußeren Brennort des Reflektors gehalten, wenn das Antriebsmittel zwischen der Vorder- und Rückseite des Reflektors an einer Reflektorseite an Halteelementen des Reflektors befestigt sind, wobei parallel zur Drehachse der Blendenwelle Positionierungsmittel von Reflektor und Antriebsmittel ineinandergesteckt sind, die das die Blendenwelle halternde Antriebsmittel zur Reflexionsfläche des Reflektors positionieren.According to a preferred embodiment, the diaphragm shaft is provided with a Storage means at a free end portion by the holder and the Bearing shell of the reflector radially and axially supported while the Shield shaft with the other free end section in one on the reflector salaried drive means of the diaphragm shaft supported radially to the axis of rotation and is mounted axially floating. This allows between the aperture shaft and the drive means no tensions occur. The aperture is held by the drive means exactly to the outer focal point of the reflector, when the drive means between the front and back of the reflector on a reflector side are attached to holding elements of the reflector, wherein Positioning means of reflector parallel to the rotation axis of the shutter shaft and drive means are inserted into each other, which holds the diaphragm shaft holder Position the drive unit towards the reflecting surface of the reflector.

Bei einer anderen vorteilhaften Weiterbildung der Erfindung ist die Blendenwelle mit jeweils einem an ihren beiden Endabschnitten angeordneten Lagerungsmittel von dem Halter in einer Lagerschale des Reflektors gehaltert ist, wobei ein Endabschnitt der Blendenwelle mit einem am Reflektor angeordneten Antriebsmittel über ein Getriebe gekoppelt ist. Dadurch sind beide Lagerschalen des Reflektors und die Reflexionsfläche des Reflektors zusammen von ein und demselben verstellbaren Werkzeugteil entformt und somit ist die Blendenwelle sehr genau zu dem äußeren Brennort des elliptischen Reflektors angeordnet.In another advantageous embodiment of the invention, the diaphragm shaft each arranged with one at its two end portions Storage means supported by the holder in a bearing shell of the reflector is, wherein an end portion of the diaphragm shaft with one on the reflector arranged drive means is coupled via a transmission. Thereby are both bearing shells of the reflector and the reflection surface of the reflector demolded from one and the same adjustable tool part and Thus, the aperture is very close to the outer focal point of the arranged elliptical reflector.

Ein weiterer besonderer Vorteil der Erfindung besteht darin, dass der Halter die Lichtaustrittsöffnung des Reflektors umgibt und sowohl zur Halterung des Scheinwerfers als auch eines Abschatters dient, der benachbart zur Blendenwelle verläuft und zumindest in einer Drehstellung der Blendenwelle zusammen mit der Blendenwelle störende Lichtstrahlen abschirmt. Dadurch ist für den Halter der Blendenwelle kein gesondertes Teil notwendig. Another particular advantage of the invention is that the holder the Light exit opening of the reflector surrounds and both for holding the Headlamps as well as a Abschatters, which adjacent to Aperture shaft extends and at least in a rotational position of the diaphragm shaft shields interfering light rays together with the aperture. This is for the holder of the diaphragm shaft no separate part necessary.
