Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Federlenkers gemäß dem Oberbegriff des Anspruchs 1, sowie einen nach dem Verfahren hergestellten Federlenker gemäß dem Oberbegriff des Anspruches 6.The invention relates to a method for producing a spring link according to the preamble of claim 1, and to a spring link produced by the method according to the preamble of claim 6.
Aus den Druckschriften
Eine Verbesserung der Korrosionseigenschaften wird durch die Verwendung eines Gussverfahrens erreicht. Aus der
Es ist Aufgabe der Erfindung die Korrosionseigenschaften und die Aerodynamik eines Federlenkers zu verbessern.It is an object of the invention to improve the corrosion properties and the aerodynamics of a spring link.
In bekannter Weise umfasst ein einteiliger Federlenker einen radseitigen und einen aufbauseitigen Anbindungsabschnitt, wobei zudem zwischen dem radseitigen und dem aufbauseitigen Anbindungsabschnitt, eine Abstützungsfläche für ein Federelement vorgesehen ist.In a known manner, a one-piece spring link comprises a wheel-side and a body-side connecting portion, wherein also provided between the wheel-side and the body-side connecting portion, a support surface for a spring element.
Die Aufgabe wird durch die kennzeichnenden Teile des Anspruches 1 gelöst.The object is solved by the characterizing parts of claim 1.
Die Unteransprüche stellen eine vorteilhafte Weiterbildung der Erfindung dar.The subclaims represent an advantageous development of the invention.
Erfindungsgemäß ist der Federlenker derart gestaltet, dass dieser eine aerodynamische Fläche aufweist, die parallel beabstandet zur Abstützungsfläche angeordnet ist. Ferner ist die aerodynamische Fläche über eine Stirnfläche mit der Abstützungsfläche verbunden, wodurch sich für den Lenker eine Querschnitts-/Profilstruktur ergibt, die wenigstens in einer Querrichtung, die quer zur Normalen der Abstützungsfläche und quer zur axialen Erstreckung des Federlenkers liegt, offen ist.According to the invention, the spring link is designed such that it has an aerodynamic surface, which is arranged parallel spaced from the support surface. Further, the aerodynamic surface is connected via an end face to the support surface, resulting in a cross-sectional / profile structure for the arm which is open at least in a transverse direction transverse to the normal of the support surface and transverse to the axial extent of the spring arm.
Die aerodynamische Fläche liegt vorzugsweise wenigstens teilweise der Abstützungsfläche gegenüber. Die aerodynamische Fläche kann sich vorzugsweise in ihrer Querrichtung auch über die Abstützungsfläche hinaus erstrecken. Quer im Sinne der Erfindung bedeutet, ein Winkel zwischen 80° und 100°.The aerodynamic surface is preferably at least partially opposite the support surface. The aerodynamic surface may preferably also extend beyond the support surface in its transverse direction. Cross in the sense of the invention means an angle between 80 ° and 100 °.
Gemäß einer weiteren vorteilhaften Ausgestaltung kann in Verlängerung der Stirnseite des Profils ein Steinschlagschutz vorgesehen sein, der ebenfalls im Gussprozess erzeugt wird. In einer weiteren Ausgestaltung ist die Ausnehmung für ein Lager zur Anbindung an den Fahrzeugaufbau so angeordnet, dass die Lagerachse parallel zur Querrichtung liegt. Dies vereinfacht die Ausformung eines Lagersitzes.According to a further advantageous embodiment, a rockfall protection can be provided in extension of the end face of the profile, which is also produced in the casting process. In a further embodiment, the recess for a bearing for connection to the vehicle body is arranged so that the bearing axis is parallel to the transverse direction. This simplifies the formation of a bearing seat.
Der erfindungsgemäße Lenker, kann vorzugsweise Versteifungsstrukturen aufweisen, die quer zur axialen Ausdehnung des Federlenkers liegen. Die Versteifungsstrukturen sind vorzugsweise als Streben oder Rippen ausgebildet und verbinden die Aerodynamikfläche mit der Abstützungsfläche. Dadurch kann mit einem geringen Materialeinsatz eine hohe Belastbarkeit des Lenkers erreicht werden.The handlebar according to the invention, may preferably have stiffening structures which lie transversely to the axial extent of the spring link. The stiffening structures are preferably designed as struts or ribs and connect the aerodynamic surface with the support surface. This allows a high load capacity of the handlebar can be achieved with a low material usage.
Eine vorteilhafte Ausgestaltung des Lenkers ergibt sich durch eine im Wesentlichen u-förmige Profilgestaltung, wobei an einem ersten Schenkel die Abstützungsfläche angeordnet ist und dem der Abstützungsfläche gegenüberliegenden Schenkel eine aerodynamische Fläche angeformt ist. Die beiden Schenkel des u-förmigen Profils sind über die Stirnfläche verbunden. Vorzugsweise ist die Stirnseite im verbauten Zustand in Fahrtrichtung ausgerichtet.An advantageous embodiment of the handlebar results from a substantially U-shaped profile design, wherein the support surface is arranged on a first leg and the leg opposite the support surface an aerodynamic surface is formed. The two legs of the U-shaped profile are connected via the end face. Preferably, the front side is aligned in the installed state in the direction of travel.
In einer weiteren vorteilhaften Ausgestaltung kann der Lenker an seiner Stirnfläche Durchbrechungen aufweisen. Diese Maßnahme führt zu einer Gewichtsreduktion des Lenkers und kann vorteilhaft die aerodynamischen Eigenschaften des Lenkers beeinflussen.In a further advantageous embodiment, the handlebar may have perforations on its end face. This measure leads to a weight reduction of the handlebar and can advantageously influence the aerodynamic properties of the handlebar.
Ferner betrifft die Erfindung ein Verfahren zur Herstellung eines Federlenkers in einem Druckgussverfahren. Dieses zeichnet sich dadurch aus, dass die Entformungsrichtung quer zur Normalen der Abstützungsfläche und quer zur axialen Erstreckung des Federlenkers liegt (im Folgenden Querrichtung bezeichnet).Furthermore, the invention relates to a method for producing a spring link in a die-casting process. This is characterized in that the Entformungsrichtung is transverse to the normal of the support surface and transverse to the axial extent of the spring link (hereinafter referred to as transverse direction).
Das Druckgussverfahren kann vorzugsweise ein Leitmetallverfahren, beispielsweise ein Aluminiumgussverfahren sein.The die-casting method may preferably be a conductive metal method, for example, an aluminum casting method.
Eine solche Entformungsrichtung ermöglicht eine entgegen der Fahrtrichtung offene Struktur eines Lenkers. Dadurch wird erreicht, dass die untere Seite im Wesentlichen geschlossen ausgebildet sein kann und als aerodynamische Fläche wirkt. Eine aerodynamische Fläche kann auf diese Weise bereits bei der Herstellung in den Federlenker integriert werden.Such Entformungsrichtung allows an open towards the direction of travel structure of a handlebar. This ensures that the lower side can be formed substantially closed and acts as an aerodynamic surface. An aerodynamic surface can be integrated in this way already during manufacture in the spring link.
Ein weiterer Vorteil ergibt sich bei einer Entformung in der Querrichtung daraus, dass die aufbauseitige Anbindungsstelle, die die Aufnahme für ein Lager bereitstellt, derart geformt werden kann, dass bereits der Lagersitz durch das Gussverfahren gebildet wird, ohne dass ein Schieberelement notwendig ist. Dies ist insbesondere für die Gestaltung des Lenkerauges, dem aufbauseitigen Anschlussteil des Federlenkers von Vorteil. Dieses kann ohne die Verwendung eines Schieberelements und damit deutlich passgenauer gefertigt werden. Dies erspart eine nachträgliche Bearbeitung des Federlenkers. A further advantage results from a demolding in the transverse direction from the fact that the body-side connection point, which provides the receptacle for a bearing, can be shaped so that the bearing seat is already formed by the casting process, without a slide element is necessary. This is particularly advantageous for the design of the handlebar eye, the body-side connector part of the spring link. This can be made without the use of a slider element and thus significantly more accurate. This saves a subsequent processing of the spring link.
Bei einer Gestaltung des Lenkers durch Nutzung der erfindungsgemäßen Entformungsrichtung, ist es nunmehr möglich Versteifungsstrukturen auf einfache Weise quer zur axialen Ausdehnung des Federlenkers anzulegen.In a design of the handlebar by using the demolding according to the invention, it is now possible to apply stiffening structures in a simple manner transverse to the axial extent of the spring link.
Weitere Vorteile, Merkmale und Anwendungsmöglichkeiten der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung in Verbindung mit den in den Zeichnungen dargestellten Ausführungsbeispielen.Further advantages, features and possible applications of the present invention will become apparent from the following description in conjunction with the embodiments illustrated in the drawings.
