Description

Für die Federung bei Vorderradgabeln für Fahr-und Motorräder sind Ausführungen bekannt, bei «-elchen zwischen den schwingenden Teilen Blattfedern angeordnet sind. Bei diesen Ausführungen ist jedoch unvollkommen, daß sie entweder, wie in Fig. i der Zeichnung dargestellt, eine zusätzliche Gelenkverbindung x oder, wie in Fig. z dargestellt, außer der beweglichen Gabel y noch eine feste Gabel z benötigen.For the suspension of front forks for bicycles and motorcycles Versions known, with «-elchen leaf springs between the vibrating parts are arranged. What is imperfect with these explanations is that they either as shown in Fig. i of the drawing, an additional articulated connection x or, As shown in Fig. z, in addition to the movable fork y still a fixed fork z require.

Die Erfindung bezweckt, die Federung im Aufbau zu vereinfachen und in der Wirkung zu verbessern. Dieser Forderung ist in dem in Fig. 3 dargestellten Ausführungsbeispiel dadurch entsprochen, daß die Blattfederpakete c das bewegliche Gabelgestell a direkt mit dem Gabelschaft b verbinden, so däß eine feste Gabel oder zusätzliche Gelenkverbindungen wegfallen. Diese Anordnung gestattet dem freien Gabelende a', insbesondere bei der Aufnahme waagerechter Stöße, unbehindert auszuschwingen.The aim of the invention is to simplify the structure of the suspension and to improve its effect. This requirement is met in the embodiment shown in Fig. 3 in that the leaf spring assemblies c connect the movable fork frame a directly to the fork shaft b , so that a fixed fork or additional articulated connections are omitted. This arrangement allows the free fork end a ', in particular when absorbing horizontal impacts, to swing out unhindered.

Zur Verschraubung der Blattfederpakete c am Gabelschaft b dienen die dort am oberen und am unteren Ende befindlichen Kugellagerringe, während zur Verschraubung am Gabelgestell a in die Blattfederpakete gemäß Fig. 4 Langlöcher c' gebohrt sind, die eine einstellbare Schrägneigung des Gabelgestelles erlauben. Um den in Fig.3 in Strichpunktlinien dargestellten Federhub zu begrenzen, ist am Gabelschaft b ein Anschlag la angebracht, welcher zugleich als Lampenhalter ausgebildet sein kann.To screw the leaf spring assemblies c on the steerer tube b, the ball bearing rings located there at the upper and lower end are used, while for screwing the fork frame a into the leaf spring assemblies according to FIG. In order to limit the spring stroke shown in dash-dotted lines in FIG. 3, a stop la is attached to the fork shaft b , which can also be designed as a lamp holder.
