Abstract
Description
Die Erfindung betrifft die Anordnung eines Wischerarmes an der Antriebswelle eines Scheibenwischers, insbesondere eines Frontscheibenwischers an einem Fahrzeug.The The invention relates to the arrangement of a wiper arm on the drive shaft a windscreen wiper, in particular a windshield wiper on a vehicle.

Es ist Aufgabe der Erfindung, eine alternative Anordnung eines Wischerarmes an der Antriebswelle eines Scheibenwischers nach dem Oberbegriff des Anspruchs 1 zu gestalten, mit der die zu übertragenden Antriebskräfte höher sein können.It The object of the invention is an alternative arrangement of a wiper arm on the drive shaft of a windscreen wiper according to the preamble of claim 1, with which the driving forces to be transmitted to be higher can.
Diese Aufgabe wird bei einer Wischerarmanordnung nach dem Oberbegriff des Anspruchs 1 durch dessen kennzeichnende Merkmale gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen aufgeführt.These Task is in a wiper arm assembly according to the preamble of claim 1 solved by its characterizing features. advantageous Embodiments are listed in the subclaims.
Die Erfindung besteht darin, dass die in einem fahrzeugfesten Lagerkörper gelagerte Antriebswelle für den Wischerarm einer Scheibenwischeranlage in ihrem dem Wischerarm zugewandten Endbereich an der Außenseite einer Fahrzeugkarosserie eine Aufnahmegabel zur formschlüssigen Anordnung des im Querschnitt mit dieser Aufnahmegabel korrespondierenden Endstückes und ein Befestigungselement, insbesondere eine Gewindebohrung, für dieses aufweist. Dabei sind die Aufnahmegabel und das Endstück so dimensioniert, dass die erforderlichen Antriebskräfte für den Wischerarm übertragen werden können. Der Durchmesser der Antriebswelle ist um ein Mehrfaches größer als der einer bekannten Wischerwelle, und das Endstück des Wischerarmes weist in der Aufnahmegabel einen Querschnitt auf, der wenigstens ebenso groß ist wie der Querschnitt eines Endstückes im Bereich des Aufnahmekonus der bekannten Wischerwelle. Durch diese Gestaltung haltert die Antriebswelle den angeschlossenen Wischerarm drehfest und kann zudem mit diesem bündig abschließen, wodurch sich eine Reduzierung der Bauhöhe der Wischerarmanordnung ergibt. Wesentlich ist jedoch, dass durch den Formschluss zwischen dem Endstück des Wischerarmes und der Aufnahmegabel eine Erhöhung der übertragbaren Antriebskräfte erreicht wird. Zudem kann der Wischerarm definiert an der Antriebswelle positioniert werden.The Invention is that stored in a vehicle-fixed bearing body Drive shaft for the wiper arm of a windshield wiper system in its wiper arm facing end portion on the outside of a vehicle body Pick-up fork for positive locking Arrangement of the cross-section corresponding to this receiving fork end piece and a fastener, in particular a threaded bore, for this having. The receiving fork and the end piece are dimensioned in this way, that transmit the required driving forces for the wiper arm can be. The diameter of the drive shaft is several times greater than a known wiper shaft, and the end of the wiper arm points in the receiving fork on a cross-section that is at least as large as the cross section of an end piece in the region of the receiving cone of the known wiper shaft. Through this Design holds the drive shaft to the connected wiper arm rotatable and can also complete flush with this, which a reduction in the height the wiper arm arrangement results. It is essential, however, that through the positive connection between the end of the wiper arm and the Pickup fork an increase the transferable driving forces is reached. In addition, the wiper arm defined on the drive shaft be positioned.
Die Aufnahmegabel kann auf einfache Weise durch eine quer zur Achse der Antriebswelle verlaufende, mittig angeordnete Ausnehmung mit einem nach dem Lagerkörper zu verjüngten trapezförmigen Querschnitt gebildet sein. Eine derartige Ausnehmung ist technologisch einfach einzubringen, und deren trapezförmiger Querschnitt erleichtert die Montage des Wischerarmes. Die Befestigung des Endstückes, dass in der Regel das Spannstück des Wischerarmes ist, in der Aufnahmegabel, erfolgt durch eine Befestigungsschraube, die während des Betriebes des Scheibenwischers den Formschluss sicherstellt.The Pick-up fork can easily by a transverse to the axis the drive shaft extending, centrally arranged recess with one after the bearing body too rejuvenated trapezoidal cross-section be formed. Such a recess is technologically simple and whose trapezoidal Cross-section facilitates the installation of the wiper arm. The attachment of the tail, that usually the clamping piece of the wiper arm is, in the receiving fork, carried by a fixing screw, the while the operation of the windscreen wiper ensures the positive connection.
In bevorzugter Ausführung ist die Antriebswelle mit einer Lagerplatte versehen, deren Durchmesser erheblich größer als der Durchmesser der Antriebswelle ist und die auf der Seite des anzuordnenden Scheibenwischers eine Gleitlagerfläche zur formschlüssigen Anlage am Lagerkörper ausbildet. Damit ist ein Plattenlager gestaltet, bei dem über die Lagerplatte ein wesentlicher Teil der beim Betreiben der Scheibenwischeranlage an der Antriebswelle auftretenden Kräfte in den Lagerkörper eingeleitet und von diesem aufgenommen wird. Der Vorteil liegt in einer Vereinfachung der Lagerkonstruktion und in einer weiteren Reduzierung der Bauhöhe der Lagereinrichtung.In preferred embodiment the drive shaft is provided with a bearing plate whose diameter considerably larger than the diameter of the drive shaft is on the side of the windscreen wiper to be arranged a sliding bearing surface for positive engagement on the bearing body formed. Thus, a plate bearing is designed in which on the bearing plate an essential part of operating the windshield wiper system introduced at the drive shaft forces introduced into the bearing body and is absorbed by this. The advantage is in a simplification the bearing structure and in a further reduction in the height of the storage facility.
Zur Halterung der Lagerplatte am Lagerkörper können an diesem zwei Halterungselemente ausgebildet sein, die die Lagerplatte an derem Rand auf der der Gleitfläche abgewandten Seite hintergreifen und diese mit ihrer Gleitfläche in formschlüssiger Anlage am Lagerkörper halten. Zur Montage am Lagerkörper ist die Lagerplatte in ihrem Randbereich mit zwei Ausnehmungen versehen, die in ihrer Anordnung, Größe und Gestalt mit den Halterungselementen korrespondieren, derart, dass diese mit Spiel durch die Ausnehmungen passen und die Antriebswelle mit der Lagerplatte mit diesen Ausnehmungen bajonettverschlussartig an den Halterungselementen vorbei bis zur Anlage der Gleitfläche am Lagerkörper geführt und anschließend verdreht wird, wonach die Halterungselemente in der Montageposition und den Betriebspositionen die Lagerplatte hintergreifen.To hold the bearing plate on the bearing body can be formed on this, two support elements, which engage behind the bearing plate on the edge on the side facing away from the sliding surface and keep them with their sliding surface in positive engagement with the bearing body. For mounting on the bearing body, the bearing plate is provided in its edge region with two recesses which correspond in their arrangement, size and shape with the support members, such that they match with clearance through the recesses and the drive shaft with the bearing plate with these recesses bayonet-like Retaining elements over until the system of the sliding surface on the bearing body guided and then twisted, after which the support members engage behind the bearing plate in the mounting position and the operating positions.
