Description

Scheibenwischvorrichtung, insbesondere für ein KraftfahrzeugWindscreen wiper device, in particular for a motor vehicle
Stand der TechnikState of the art
Die Erfindung betrifft eine Scheibenwischvorrichtung, insbesondere für ein Kraftfahrzeug, nach dem Oberbegriff des unabhängigen Anspruchs.The invention relates to a windshield wiper device, in particular for a motor vehicle, according to the preamble of the independent claim.
Es sind schon zahlreiche Scheibenwischvomchtungen, beispielsweise aus DE-A-199 03 140 bekannt, die einen Montageabschnitt und ein Befestigungselement zur Befestigung der Scheibenwischvorrichtung in oder am Kraftfahrzeug aufweisen. Zur Montage im Kraftfahrzeug wird die Scheibenwischvorrichtung üblicherweise auf dieNumerous windshield wiper devices are known, for example from DE-A-199 03 140, which have a mounting section and a fastening element for fastening the windshield wiper device in or on the motor vehicle. For mounting in the motor vehicle, the windshield wiper device is usually on the
Befestigungspunkte an der Karosserie des Kraftfahrzeugs aufgesetzt und mittels Schrauben als Befestigungselementen verschraubt. Dies ist relativ aufwendig und benötigt zahlreiche Arbeitsschritte.Fastening points placed on the body of the motor vehicle and screwed by means of screws as fastening elements. This is relatively complex and requires numerous work steps.
Weiterhin ist bekannt, die Scheibenwischvorrichtung an der Karosserie desIt is also known that the windshield wiper device on the body of the
Kraftfahrzeugs anzuschweißen oder anzukleben, um die Befestigungselemente einzusparen und die Befestigung in einem Schritt vornehmen zu können. Problematisch ist hierbei, dass die Scheibenwischvorrichtung nicht mehr vom Kraftfahrzeug lösbar ist und somit ein Austausch bei einem Defekt nur unter erhöhtem Aufwand möglich ist.Welding or gluing motor vehicle in order to save the fastening elements and to be able to carry out the fastening in one step. The problem here is that the windshield wiper device can no longer be detached from the motor vehicle, and an exchange in the event of a defect is therefore only possible with increased effort.
Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Scheibenwischvorrichtung mit den Merkmalen des Hauptanspruchs hat den Vorteil, dass durch die Halterung des Befestigungselementes mit einem Hilfselement, die Befestigungselemente in den Montageabschnitt der Scheibenwischvorrichtung eingesetzt werden können und dort gehaltert sind. Auf diese Weise können die Befestigungselemente bereits beim Hersteller der Scheibenwischvorrichtung eingesetzt werden und beim Transport zum Kraftfahrzeug- Hersteller nicht herausfallen, so dass die Scheibenwischvorrichtung bei der Montage lediglich in die entsprechende Position gebracht und die Befestigungselemente verriegelt werden müssen. Ein separates Einsetzen der Befestigungselemente entfällt daher, wodurch Kosten bei der Montage eingespart werden können.The windshield wiper device according to the invention with the features of the main claim has the advantage that by fastening the fastening element with an auxiliary element, the fastening elements in the mounting section of the Windshield wiper device can be used and are held there. In this way, the fastening elements can already be used by the manufacturer of the windshield wiper device and cannot fall out during transport to the motor vehicle manufacturer, so that the windshield wiper device only has to be brought into the corresponding position during assembly and the fastening elements have to be locked. A separate insertion of the fasteners is therefore unnecessary, which can save costs during assembly.
Durch die in den Unteransprüchen aufgeführten Maßnahmen ergeben sich vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Merkmale.The measures listed in the subclaims result in advantageous developments and improvements of the features specified in the main claim.
Besonders vorteilhaft ist hierbei, wenn das Befestigungselement bereits in der Montageposition beweglich gehaltert ist. Auf diese Weise wird die Montage vereinfacht. Darüber hinaus ist durch die bewegliche Halterung ein einfacher Toleranzausgleich möglich.It is particularly advantageous here if the fastening element is already movably held in the assembly position. In this way, assembly is simplified. In addition, a simple tolerance compensation is possible due to the movable holder.
Vorteilhafterweise ist das Befestigungselement als Schraube ausgebildet, da diese in großen Stückzahlen kostengünstig erhältlich sind und eine lösbare und sichere Verbindung der Scheibenwischvorrichtung in oder am Kraftfahrzeug gewährleisten.The fastening element is advantageously designed as a screw, since these are inexpensively available in large quantities and ensure a detachable and secure connection of the windshield wiper device in or on the motor vehicle.
Von besonderem Vorteil ist es, wenn das Hilfselement als Scheibe, insbesondere als Kunststoffscheibe ausgebildet ist. Scheiben, insbesondere Kunststoffscheiben sind kostengünstig und leicht mit Schrauben verbindbar, insbesondere muss hierzu kein Gewinde in die Scheibe geschnitten werden.It is particularly advantageous if the auxiliary element is designed as a disk, in particular as a plastic disk. Disks, in particular plastic disks, are inexpensive and easy to connect with screws; in particular, no thread has to be cut into the disk for this.
Weiterhin ist es als vorteilhaft anzusehen, wenn der Montageabschnitt ein Dämpfungselement aufweist und das Befestigungselement das Dämpfungselement durchgreift. Damit kann auch auf das separate Anbringen vom Dämpfungselementen zwischen Scheibenwischvorrichtung und der Karosserie des Kraftfahrzeugs verzichtet werden.Furthermore, it is to be regarded as advantageous if the mounting section has a damping element and the fastening element extends through the damping element. It is therefore also possible to dispense with the separate attachment of the damping elements between the windshield wiper device and the body of the motor vehicle.
Besonders vorteilhaft ist es hierbei, wenn das Dämpfungselement aus einem elastischen Material, insbesondere aus Gummi besteht und das Befestigungselement zumindest teilweise umringt. Ein optimales Dämpfungsverhalten kombiniert mit der sicheren Halterung des Befestigungselements mit dem Hilfselement ist es besonders vorteilhaft, wenn das Hilfselement aus härterem Material besteht als das Dämpfungselement.It is particularly advantageous here if the damping element consists of an elastic material, in particular rubber, and at least partially surrounds the fastening element. Optimal damping behavior combined with the secure mounting of the fastening element with the auxiliary element, it is particularly advantageous if the auxiliary element consists of harder material than the damping element.

In Figur 1 ist eine erfindungsgemäße Scheibenwischvorrichtung 10 in einer Seitenansicht gezeigt. Diese umfasst im Wesentlichen ein Trägerrohr 12, an dessen Enden jeweils einIn Figure 1, a windshield wiper device 10 according to the invention is shown in a side view. This essentially comprises a carrier tube 12, at the ends of which one
Wischerlager 14 angeordnet ist. Aus Übersichtlichkeitsgründen ist hier nur ein Ende des Trägerrohrs 12 der Scheibenwischvorrichtung 10 gezeigt, das andere Ende ist mutativ mutantis im Wesentlichen gleich.Wiper bearing 14 is arranged. For reasons of clarity, only one end of the carrier tube 12 of the windshield wiper device 10 is shown here, the other end is mutually mutantis essentially the same.
Das Wischerlager 14 umfasst im Wesentlichen drei Abschnitte, einenThe wiper bearing 14 essentially comprises three sections, one
Befestigungsabschnitt 16 der zur Befestigung des Wischerlagers am Trägerrohr 12 dient, einen Lagerabschnitt 18, der sich unmittelbar an dem Befestigungsabsclmitt 16 anschließt und eine Wischerwelle 20 lagert, sowie einen Montageabschnitt 22, der zur Befestigung der Scheibenwischvorrichtung 10 am Kraftfahrzeug dient. Der Montageabschnitt 22 besteht im Wesentlichen aus einer Platte 24, deren Ebene senkrecht zur Längsachse derFastening section 16 which is used to fasten the wiper bearing to the support tube 12, a bearing section 18 which adjoins the fastener 16 and supports a wiper shaft 20, and a mounting section 22 which serves to fasten the windshield wiper device 10 to the motor vehicle. The mounting section 22 essentially consists of a plate 24, the plane of which is perpendicular to the longitudinal axis of the
Wischerwelle 20 angeordnet ist. Die Platte 24 ist an ihrer Berandung von Außenwänden 26 begrenzt, die sich kragenartig in die Höhe, also in Richtung der Längsachse der Wischerwelle 20 erstrecken. Die Platte 24 weist eine U-förmige Einkerbung als Aufnahme 37 auf, in die ein Dämpfungselement 30 eingesetzt ist. Das Dämpfiingselement 30 besteht im Wesentlichen aus einer zylinderförmigen Gummimuffe, deren Durchmesser etwa in der Mitte ihrer Längserstreckung verjüngt ist. Alternativ dazu kann die Gummimuffe natürlich auch länglich oder ellipsenförmig sein. Zur Stabilisierung ist im Innern des hohlzylinderförmigen Dämpfungselementes 30 noch eine Hülse 31 aus Metall emgesetzt. In das Dämpfungselement 30 ist das als Schraube ausgebildete Befestigungselement 32 eingesetzt und durchgreift dieses in voller Länge. Alternativ kann das Befestigungselement 32 natürlich auch als Niete oder als Bolzen oder ähnliches ausgebildet sein.Wiper shaft 20 is arranged. The edge of the plate 24 is delimited by outer walls 26, which extend in the manner of a collar in height, that is to say in the direction of the longitudinal axis of the wiper shaft 20. The plate 24 has a U-shaped notch as a receptacle 37, into which a damping element 30 is inserted. The damping element 30 essentially consists of a cylindrical rubber sleeve, the diameter of which is tapered approximately in the middle of its longitudinal extent. Alternatively, the rubber sleeve can of course also be elongated or elliptical. For stabilization, a sleeve 31 made of metal is inserted inside the hollow cylindrical damping element 30. The fastening element 32, which is designed as a screw, is inserted into the damping element 30 and extends through it in its full length. Alternatively, the fastening element 32 can of course also be designed as a rivet or as a bolt or the like.
Die Schraube 32 ist als Sechskantschraube mit einem Sechskant 33 ausgebildet. Auf die Schraube 32 ist eine kreisscheibenförmige Kunststoffscheibe als Hilfselement 35 aufgeschraubt, so dass die Schraube 32 nicht aus dem Dämpfiingselement 30 und damit aus dem Montageabschnitt 22 herausfallen kann.The screw 32 is designed as a hexagon screw with a hexagon 33. A circular disk-shaped plastic disk is screwed onto the screw 32 as an auxiliary element 35, so that the screw 32 cannot fall out of the damping element 30 and thus out of the mounting section 22.
In Figur 2 ist das Befestigungselement 32 sowie das Dämpfungselement 30 im Detail dargestellt. Das Dämpfungselement 30 ist im Wesentlichen hohlzylinderförmig ausgebildet. Entlang seiner Längserstreckung weist es eine ringförmige Nute 35 auf, die zur Aufnahme in die Platte 24 dient. Das Dämpfungselement ist aus einem elastischenThe fastening element 32 and the damping element 30 are shown in detail in FIG. The damping element 30 is essentially hollow-cylindrical. Along its longitudinal extent, it has an annular groove 35, which is used to receive the plate 24. The damping element is made of an elastic
Gummimaterial ausgebildet und sitzt fest in der Aufnahme 37. Im Zentrum des Dämpfungselementes 30 ist eine Hülse 31 eingesetzt, die zur Stabilisierung dient. In dieser Hülse ist die Sechskantschraube 32 frei beweglich.Rubber material formed and sits firmly in the receptacle 37. In the center of the damping element 30, a sleeve 31 is used, which serves for stabilization. The hexagon screw 32 is freely movable in this sleeve.
In einer Variation kann die Sechskantschraube an Ihrem freien, dem Sechskant 33 abgewandten Ende, ein zylinderförmigen Steckabschnitt aufweisen, an den sich der Gewindeabschnitt anschließt. Der Steckabschnitt weist kein Gewinde auf und besitzt einen Durchmesser, der kleiner ist als der Kerndurchmesser des Gewindeabschnitts. Beim Einbau der Scheibenwischvorrichtung 10 wird durch den Steckabschnitt dann ein selbstzentrierender Effekt erzielt. Benachbart zum Sechskant 33 weist dieIn a variation, the hexagon screw can have a cylindrical plug-in section at its free end facing away from the hexagon 33, to which the threaded section adjoins. The plug section has no thread and has a diameter that is smaller than the core diameter of the threaded section. When the windshield wiper device 10 is installed, the plug-in section then achieves a self-centering effect. Adjacent to the hexagon 33 has the
Sechskantschraube noch eine kreisscheibenförmige Platte 38 auf. Diese sorgt für eine gleichmäßige Druckverteilung auf das Dämpfungselement 30.Hexagon screw on a circular disk-shaped plate 38. This ensures a uniform pressure distribution on the damping element 30.
In Figur 3 ist das Befestigungselement 32, das Dämpfungselement 30 sowie das Hilfselement 35 im Anlieferzustand beim Kraftfahrzeughersteller in einer Querschnittsdarstellung gezeigt. Im montierten Zustand ist das Dämpfungselement 30 in die U-förmige Kerbe 37 der Platte 24 eingesetzt. Die Schraube als Befestigungselement 32 ist in die Ringmuffe eingesteckt. Zum Haltern der Schraube, damit diese gegen ein Herausfallen während des Transports gesichert ist, ist die Kunststoffscheibe als Hilfselement 35 auf das Gewinde der Schraube 33 aufgeschraubt. Bei der Montage verbleibt die Kunststoffscheibe 35 auf der Schraube 32 und ist in montierter Position zwischen dem Dämpfungselement 30 und dem Karosserieblech bzw. dem Befestigungsblech am Kraftfahrzeug angeordnet. Dadurch das die Kunststoffscheibe 35 aus härterem Material besteht, als das Dämpfungselement 30 ist ein optimaler Wirkungsgrad bei der Dämpfung gewährleistet.In FIG. 3, the fastening element 32, the damping element 30 and the auxiliary element 35 are in one in the delivery state at the motor vehicle manufacturer Cross-sectional representation shown. In the assembled state, the damping element 30 is inserted into the U-shaped notch 37 of the plate 24. The screw as fastening element 32 is inserted into the ring sleeve. To hold the screw so that it is secured against falling out during transport, the plastic washer is screwed onto the thread of the screw 33 as an auxiliary element 35. During assembly, the plastic disc 35 remains on the screw 32 and is arranged in the assembled position between the damping element 30 and the body panel or the mounting plate on the motor vehicle. As a result of the fact that the plastic disc 35 is made of a harder material than the damping element 30, an optimal efficiency in damping is ensured.
Alternativ kann die kreisscheibenförmige Kunststoffscheibe 35 auch aus einem dünnen Blech ausgebildet sein. In einer weiteren Variation kann die Scheibe 35 auch quadratisch, rechteckig oder in anderer Weise geformt sein. Typischerweise ist die Scheibe etwa zwischen 0,5 und 1,5 mm dick. Vorzugsweise ist die Scheibe etwa 0,8 mm dick und relativ steif, so dass eine gute Schraubverbindung und eine leichte Gängigkeit bei der Montage der Wischanlage gewährleistet ist.Alternatively, the circular disk-shaped plastic disk 35 can also be formed from a thin sheet. In a further variation, the disk 35 can also be shaped square, rectangular or in some other way. Typically, the disc is between about 0.5 and 1.5 mm thick. The pane is preferably approximately 0.8 mm thick and relatively stiff, so that a good screw connection and easy movement during assembly of the wiper system is ensured.
In einer weiteren Variation kann das Befestigungselement 32 auch mit einer Sollbruchstelle versehen sein, so dass ein wirksamer Fußgängeraufprallschutz bezüglich der Wischerwellen 20 des Kraftfahrzeugs gewährleistet ist. In a further variation, the fastening element 32 can also be provided with a predetermined breaking point, so that effective pedestrian impact protection with regard to the wiper shafts 20 of the motor vehicle is ensured.
