Description

Vorderradfederung für Motorräder Die Erfindung betrifft eine Vorderradfederung für Motorräder, die in einem vollständig geschlossenen schmieröldichten Gehäuse eingeschlossen ist. Es sind bereits derartige Federungen bekannt, bei denen die Radachse von einem einarmigen Hebel getragen wird, der auf einer öldichten, durch die Wand des Gehäuses geführten Welle befestigt ist, auf welcher im Innern des Gehäuses ein im wesentlichen dem äußeren paralleler Hebel angebracht ist, der auf eine im Gehäuse befindliche Feder wirkt. Bei den bekannten Konstruktionen dieser Art hat man entweder die Kraft von dem Innenhebel durch einen besonderen Lenker auf einen Gleitkolben. übertragen, der seinerseits auf die Feder wirkte, oder man hat zwischen dem Endstück der Feder und dem Ende des Innenhebels eine kugelförmige Führung vorgesehen und das Endstück der Feder an einer mittleren Stange geführt, um welche das Ende des Hebels herumgreift. lach der Erfindung wird eine erheblich einfachere, billigere und betriebssichere Ausführung geschaffen, indem das freie Ende des Innenhebels sich mit einem Kugelkopf in eine Vertiefung eines im unteren Ende einer Feder steckenden Bolzens stützt, wobei das Federende mit dem Bolzen frei in dem Gehäuse ohne Berührung mit den Gehäusewänden beweglich ist.Front suspension for motorcycles The invention relates to a front suspension for motorcycles in a completely closed, oil-tight housing is included. There are already such suspensions known in which the Wheel axle is carried by a one-armed lever, which is on an oil-tight, through the wall of the housing guided shaft is fixed on which inside the housing a substantially the outer parallel lever is attached to an im The spring located in the housing acts. In the known constructions of this type you either the power from the inside lever through a special handlebar on you Sliding piston. transferred, which in turn acted on the pen, or one has between the end piece of the spring and the end of the inner lever a spherical guide is provided and the end piece of the spring is guided on a central rod around which the end of the lever reaches around. According to the invention, a considerably simpler, cheaper one and reliable execution created by the free end of the inner lever with a ball head in a recess of one in the lower end of a spring Bolt supports, wherein the spring end with the bolt freely in the housing without contact is movable with the housing walls.

Die Zeichnung zeigt beispielsweise eine Ausführungsform des Erfindungsgegenstandes.The drawing shows, for example, an embodiment of the subject matter of the invention.

Auf dem äußeren Hebel 1, der die Radachse trägt, ist der Innenhebel 2 befestigt, der sich im Innern des vollständig mit Schmieröl gefüllten Gehäuses 3 befindet und um zwei auf dem Gehäuse 3 bzw. auf dessen Deckel vorgesehene Büchsen dreht. Das Ende des Hebels 2 ist kugelartig geformt. Auf diese Kugel stützt sich der Bolzen 4, der auf einem Ende eine Kugelschale und auf dem anderen Ende eine Führungsstange für die Feder 5 aufweist. Diese Feder 5 ist im Innern des Rohres angebracht, das einen Arm der Fahrradgabel bildet.The inner lever is on the outer lever 1, which carries the wheel axle 2 attached, which is located inside the housing, which is completely filled with lubricating oil 3 is located and around two cans provided on the housing 3 or on its cover turns. The end of the lever 2 is shaped like a ball. This ball is based on the bolt 4, which has a spherical shell on one end and a spherical shell on the other end Has guide rod for the spring 5. This spring 5 is inside the tube attached, which forms one arm of the bicycle fork.

Der Bolzen 4 trägt innen eine Bohrung, die zur Einbringung des Schmieröls zu den in Berührung befindlichen Teilen, und zwar zur Kugel und. zur Kugelschale, dient. Während der Winkelbewegung des Innenhebels 2 bewegt sich der Bolzen 4 auf der Kugelfläche, so daß die Feder 5 nicht auf Biegung beansprucht wird. Während des Rückkehr ubes stützt sich der Hebel 2 auf den Endanschlag 6, der aus einem eine gewisse Elastizität aufweisenden Material, wie z. B. Kork oder Gummi, besteht.The bolt 4 has a bore inside which is used for introducing the lubricating oil to the parts in contact, namely to the ball and. to the spherical shell, serves. During the angular movement of the inner lever 2, the bolt 4 moves up the spherical surface, so that the spring 5 is not subjected to bending. While of the return ubes the lever 2 is based on the end stop 6, which consists of a one material exhibiting some elasticity, such as. B. cork or rubber.

Es wird somit eine- Aufhängung erreicht, die einfach in ihrem Aufbau und sicher in ihrer Arbeitsweise ist. Selbstverständlich können alle baulichen Einzelteile je nach Notwendigkeit verändert werden, ohne deshalb das Wesen der Erfindung zu verlassen.A suspension is thus achieved which is simple in its structure and is safe in its operation. Of course, all structural components can can be changed as necessary, without therefore affecting the essence of the invention leaving.
