Description

Motorradvordergabel Die vorliegende Erfindung bezieht sich auf eine Motorradvordergabel, deren Gabelscheiden geschlossene Zellenkörper bilden, die aus zwei an den Rändern durch Falzen oder Schweißen verbundenen Blechbeilen bestehen und die ein oberes und ein unteres Schwinghebellager aufweisen. Die Gabelscheiden sind dabei symmetrisch geformt, wobei beide Gabelscheiden aus vier gleichen Blechteilen aufgebaut sein können. Der Gegenstand der Erfindung besteht darin, daß das Lager für den unteren Schwinghebel seitlich der Verbindungslinie obere Schwinghebellagermitte-Achsmitte angeordnet ist. Durch diese Exzentrizität in Verbindung mit der Symmetrie der Gabelscheiden läßt sich der bei der Gabel, je nach Gebrauch für Solo- .oder Seitenwagenmaschine, notwendige verschiedene Vorlauf einstellen, und zwar ohne jede Veränderung der Gabelcharakteristik und ohne Auswechslung von Teilen, lediglich durch Seitenverkehrung der Gabelscheiden. Durch die Seitenverkehrung wird das exzentrische untere Schwinghebellager einmal vor, einmal hinter die Verbindungslinie gelegt, und die durch die Verschiebung der Vorderachse hierdurch erzielte Vorlaufänderung ergibt sich als Funktion aus dem Betrag der Exzentrizität des unteren Schwinghebellagers. Der besondere Vorteil der Erfindung besteht darin, daß einmal ohne Auswechslung von Teilen in einfacher Weise eine Vorlaufänderung vorgenommen werden kann und zum anderen erreicht ist, daß eine Vorlaufänderung ohne Beeinflussung der Bewegungscharakteristik der Gabel erfolgt.Motorcycle front fork The present invention relates to a Motorcycle front fork, the fork blades of which form closed cell bodies that consist of consist of two sheet metal hatchets connected at the edges by folding or welding and which have an upper and a lower rocker arm bearing. The fork blades are symmetrically shaped, with both fork blades made of four identical sheet metal parts can be constructed. The object of the invention is that the bearing for the lower rocker arm on the side of the connecting line between the upper rocker arm bearing center and axis center is arranged. This eccentricity in connection with the symmetry of the fork blades can be used with the fork, depending on the use for a solo or sidecar machine, Set the necessary different advance without any change in the fork characteristics and without changing parts, just by turning the fork blades sideways. The lateral reversal makes the eccentric lower rocker arm bearing one time before, once placed behind the connecting line, and by moving the The change in lead achieved in this way results as a function of the front axle Amount of eccentricity of the lower rocker arm bearing. The special advantage of the Invention is that once without replacing parts in a simple manner a lead change can be made and on the other hand it is achieved that a The advance change takes place without influencing the movement characteristics of the fork.

In der Zeichnung ist eine Ausführungsform im Längsschnitt dargestellt.In the drawing, an embodiment is shown in longitudinal section.

Bei dieser Ausführungsform sind zur Ersparung von Werkzeugkosten zwei symmetrische Blechpreßteile a und b an den hauptbeanspruchten Stellen noch durch Blecheinlagen c, d und e verstärkt und am Rand -elektrisch nahtgeschweißt. Das vor- und zurückverlegbare untere Schwinghebellager f sitzt in dem durch das Blech d verstärkten Mittelsteg.In this embodiment, to save tooling costs, two symmetrical pressed sheet metal parts a and b are reinforced by sheet metal inserts c, d and e at the main stressed points and electrically seam-welded at the edge. The lower rocker arm bearing f, which can be moved forward and backward, sits in the central web reinforced by the sheet metal d.
