Die Erfindung bezieht Scheinwerfer für Fahrzeuge mit einem schalenförmigen Reflektor, mit einer dem Reflektor zugeordneten Lichtquelle, mit einer zwischen einer Linse und dem Reflektor angeordneten Blendenwelle, mit einem mit der Blendenwelle gekoppelten Antriebsmittel, durch welche die Blendenwelle um eine horizontale und quer zur optischen Achse verlaufende Drehachse in mehrere Drehstellungen verstellbar ist, und mit einem die Blendenwelle und das Antriebsmittel tragenden Halter.The invention relates to headlights for vehicles with a cup-shaped Reflector, with a light source assigned to the reflector, with a between a lens and the reflector arranged aperture shaft, with one with the Aperture shaft coupled drive means through which the aperture shaft by one horizontal and transverse to the optical axis rotating axis in several Rotational positions is adjustable, and with one the aperture shaft and that Drive-bearing bracket.
Ein solcher Scheinwerfer für Fahrzeuge ist aus der DE 43 35 286 A1 bekannt. Ein Lichtmodul des Scheinwerfers weist einen ellipsoidförmigen Reflektor, eine in dem Strahlengang des Reflektors angeordnete Linse und eine zwischen Reflektor und Linse eingesetzte Blendenwelle auf. Die Mantelfläche der Blendenwelle weist für jede Drehstellung der Blendenwelle eine Blendenlinie auf, welche eine Hell-Dunkel-Grenze einer Lichtfigur erzeugt. Die Blendenwelle verläuft zwischen zwei Schenkeln eines U-förmigen Halters und greift in Lageröffnungen der Schenkel ein. Ein Antriebsmittel der Blendenwelle weist einen elektrischen Motor und ein Getriebe auf, welches die Blendenwelle mit dem Getriebe koppelt. Der Motor ist außen an einem Schenkel des U-förmigen Halters angebracht und führt mit seiner Antriebswelle durch eine Öffnung des Schenkels des Halters hindurch. Dieses durch die Öffnung hindurchragende Ende der Blendenwelle ist über das Getriebe mit der Blendenwelle gekoppelt. Das Getriebe besteht aus zwei Zahnrädern, von denen eines auf der Blendenwelle und das andere auf der Antriebswelle des Motors sitzt.

Such a headlight for vehicles is known from DE 43 35 286 A1. On The headlight's light module has an ellipsoidal reflector, one in the Beam path of the reflector and a lens arranged between the reflector and Lens inserted lens. The outer surface of the diaphragm shaft points for each rotary position of the diaphragm shaft on an aperture line, which a Light-dark boundary generated by a light figure. The aperture wave runs between two legs of a U-shaped holder and engages in bearing openings of the legs on. A drive means of the diaphragm shaft has an electric motor and Gearbox, which couples the aperture shaft with the gearbox. The engine is attached to the outside of one leg of the U-shaped holder and leads with it Drive shaft through an opening of the leg of the holder. This through the opening protruding end of the diaphragm shaft is via the gearbox with the Aperture shaft coupled. The gearbox consists of two gears, one of which one sits on the aperture shaft and the other sits on the drive shaft of the engine.

Aufgabe der Erfindung ist es, den im Oberbegriff des Anspruchs 1 beschriebenen
Scheinwerfer für Fahrzeuge derart zu gestalten, daß die Lichtstrahlen der
Lichtquelle unterhalb der Blendenwelle abgeschirmt sind und der Halter aus
möglichst wenigen Teilen besteht. Diese Aufgabe wird nach der Erfindung dadurch
gelöst, daß ein unterhalb der Blendenwelle angeordneter Abschatter der Halter für
die Blendenwelle und das Antriebsmittel ist, wobei die Blendenwelle mit einem
Abschnitt in einer nach oben geöffneten Aufnahmerinne des Abschatters angeordnet
ist und der Abschatter seitlich seiner Aufnahmerinne ein Aufnahmeelement für das
Antriebsmittel aufweist.
Hierbei schirmen der Abschatter und die Blendenwelle zusammen Lichtstrahlen der
dem Reflektor zugeordneten Lichtquelle ab, und der Abschatter ist durch die
Aufnahmerinne versteift.The object of the invention is to design the headlights for vehicles described in the preamble of claim 1 such that the light rays of the light source are shielded below the aperture shaft and the holder consists of as few parts as possible. This object is achieved according to the invention in that a shader arranged below the diaphragm shaft is the holder for the diaphragm shaft and the drive means, the diaphragm shaft being arranged with a section in an upwardly open receiving groove of the shading device and the shading device on the side of its receiving groove being a receiving element for the drive means.
Here, the shader and the diaphragm shaft together shield light rays from the light source assigned to the reflector, and the shader is stiffened by the receiving channel.
Zwischen dem Antriebsmittel und der Blendenwelle bestehen nur sehr kleine Toleranzen, wenn der die Aufnahmerinne für die Blendenwelle aufweisende Abschatter und zumindest ein Teil des Aufnahmeelements einstückig ausgeführt sind. Dadurch ist die Funktion des Scheinwerfers sicher. Der Abschatter ist wärmebeständig, wenn er aus einer gegossenen Metall-Legierung besteht. Außerdem führt er über das Aufnahmeelement die im Inneren des Scheinwerfers bzw. eines Lichtmoduls des Scheinwerfers entstehende Wärme nach außen ab.There are only very small ones between the drive means and the diaphragm shaft Tolerances if the one that has the receiving channel for the diaphragm shaft Shadows and at least part of the receiving element made in one piece are. This ensures that the headlights function correctly. The shader is heat-resistant if it consists of a cast metal alloy. In addition, it guides the inside of the headlight over the receiving element or a light module of the headlamp from the heat generated to the outside.
Zwischen der Blendenwelle und dem Abschatter können keine Lichtstrahlen der Lichtquelle hindurchtreten, wenn die Aufnahmerinne sich zwischen Blendenwelle und Reflektor oder Blendenwelle und Linse erstreckt und ein oberer Rand der Aufnahmerinne im Bereich einer horizontalen Ebene angeordnet ist, in der die Drehachse der Blendenwelle verläuft. Die Blendenwelle und der Abschatter sind auch dann zusammen lichtdicht, wenn die Aufnahmerinne bedingt durch eine unregelmäßige Form der Blendenwelle einen größeren Abstand zur Blendenwelle aufweist.No light rays can between the aperture shaft and the shading Pass the light source when the receiving channel is between the aperture shaft and reflector or aperture shaft and lens extends and an upper edge of the Receiving groove is arranged in the area of a horizontal plane in which the The axis of rotation of the diaphragm shaft runs. The aperture shaft and the shader are also lightproof together if the receiving channel is caused by a irregular shape of the diaphragm shaft a greater distance from the diaphragm shaft having.
Der Abschatter weist in dem die Blendenwelle halternden Bereich eine hohe Steifigkeit auf, wenn die Aufnahmerinne in ihrer Länge durch Seitenwände begrenzt ist, in die Lageröffnungen für die Blendenwelle eingebracht sind. Ein leichtgängiges Schwenken der Blendenwelle ist gewährleistet, wenn in die Lageröffnungen jeweils eine Gleithülse für Lagerzapfen der Blendenwelle eingesetzt sind.The shader has a high one in the area holding the diaphragm shaft Stiffness when the receiving channel is limited in its length by side walls is introduced into the bearing openings for the diaphragm shaft. A smooth one Swiveling of the diaphragm shaft is guaranteed when in the bearing openings respectively a sliding sleeve is used for the journal of the diaphragm shaft.
Das Aufnahmeelement für das Antriebsmittel bildet zusammen mit dem Abschatter eine stabile Einheit, wenn das Aufnahmeelement an eine Seitenwand der durch die Seitenwände versteiften Aufnahmerinne angebracht ist.The receiving element for the drive means forms together with the shader a stable unit when the receiving element is connected to a side wall through the Side walls stiffened receiving channel is attached.
Das Antriebsmittel ist platzsparend am Scheinwerfer angeordnet, wenn das Aufnahmeelement in seiner Hauptausdehnung quer zur Drehachse der Blendenwelle verläuft und zur Rückseite des Scheinwerfers hin weist, wobei ein elektrischer Motor des Antriebsmittels auf der dem Reflektor zugewandten Seite des Aufnahmeelements angeordnet ist und der elektrische Motor über ein Getriebe des Antriebmittels mit der Blendenwelle gekoppelt ist. Hierbei baut der elektrische Motor seitlich nicht auf, da er benachbart zu dem zur Rückseite des Scheinwerfers sich verjüngenden Reflektor angeordnet ist.The drive means is arranged on the headlamp to save space if that Receiving element in its main dimension transverse to the axis of rotation of the Aperture shaft runs and points towards the back of the headlight, with a Electric motor of the drive means on the side of the reflector facing Receiving element is arranged and the electric motor via a gearbox Drive means is coupled to the aperture shaft. Here the electric motor builds not on the side, since it is adjacent to the back of the headlight itself tapered reflector is arranged.
Das Getriebe ist geschützt angeordnet, wenn das Aufnahmeelement ein Gehäuseteil für das Getriebe aufweist. Dadurch wird verhindert, daß Gegenstände, wie zum Beispiel elektrische Kabel, zwischen Zahnräder des Getriebes gelangen können und somit die Funktion des elektrischen Antriebs blockieren. Das Gehäuseteil kann durch einen abnehmbaren Gehäusedeckel abgeschlossen sein.The gear is arranged protected when the receiving element is a housing part for the transmission. This prevents objects such as Example electrical cables that can get between the gear wheels of the transmission and thus blocking the function of the electric drive. The housing part can be completed by a removable housing cover.
Der Abschatter bildet zusammen mit seiner Aufnahmerinne einen verwindungssteifen Halter, wenn der Abschatter abgewinkelte Randabschnitte aufweist.The shader forms one together with its receiving groove torsionally stiff holder if the shader has angled edge sections having.
Bei einer besonders vorteilhaften Weiterbildung der Erfindung ist an der Innenseite der Aufnahmerinne mindestens ein Anschlag für die Blendenwelle angebracht. Der Anschlag dient zur Justage der Blendenwelle und kann einstückig mit dem Abschatter ausgeführt sein. Ein Abschatter mit zwei Anschlägen kann auch bei anderen Scheinwerfervarianten mit unterschiedlichen Blendenwellen verwendet werden.In a particularly advantageous development of the invention is on the inside at least one stop for the diaphragm shaft is attached to the receiving channel. The Stop is used to adjust the diaphragm shaft and can be made in one piece with the Shadows must be executed. A shader with two stops can also other headlight variants with different aperture shafts are used become.
