Description

Vorderradfederung eines Kraftrades Die Erfindung bezieht sich auf die Radaufhängung der gelenkten Räder eines Kraftrades.Front suspension of a motorcycle The invention relates to the suspension of the steered wheels of a motorcycle.

Es ist bekannt, Vorderräder in Teleskopgabeln zu fuhren, ebenso wie es bekannt ist, die Räder an Schwingen ztt führen. Die Schwingen sind an ihrem einen Ende an der Gabel gelagert und nahe ihrem anderen Ende durch teleskopartig ineinander einschiebbare Federbeine abgefedert. Darüber hinaus ist es bekannt, die Räder nicht nur auf einer Linie dem jeweiligen Stoß aus den Unebenheiten der Straße ausweichen zu lassen, sondern sie auf einer Fläche zu führen, d. h. sie jeweils in der Stoßrichtung des Rades ausweichen zu lassen. Eine direkte Anwendung der dadurch gegebenen technischen Lehre auf die Vorderräder ist nicht möglich. da die Rückstellkräfte, die das Vorderrad eines Kraftrades in die Geradeausfahrtstellung zu bringen suchen. durch die -Nachlaufveränderungen sich ebenfalls ändern.It is known to drive front wheels in telescopic forks, as well as it is known to lead the wheels to swing ztt. The wings are on one of them End mounted on the fork and close to its other end by telescoping into each other Retractable spring struts with suspension. In addition, it is known the wheels fail only avoid the respective impact from the unevenness of the road on one line to let, but to guide them on a surface, d. H. each in the direction of thrust to let the wheel evade. A direct application of the technical Teaching on the front wheels is not possible. because the restoring forces that the front wheel seek to bring a motorcycle into the straight-ahead driving position. due to the lag changes also change.

Schließlich ist eine Vorderradaufhängung für ein Kraftrad vorgeschlagen worden, bei der das Rad an einem annähernd waagrechten, drehbar gelagerten Schwingarm gelagert ist, der von im Winkel dazu wirkenden Federteleskopen abgestützt wird. Der Schwingarm ist in seiner Drehachse in einer Gunnnibüchse federnd ,gelagert. Eine solche Gummilagerung hat zwar den `ctrtcil. daß sie Schwingungen hoher Frequenz, sogenannte Rollgeräusche. absorbiert und das Lager wartungsfrei macht. Eigentliche Federungseigenschaftert über einen weiten Wg, wie er zum Dämpfen der Stöße aus Fahrbahnunebenheiten not- wendig ist, kiinrlen einem solchen Gummilager aber nicht zugemutet werden. IHM man ein solches Lager so großräumig und die Buchse aus Gtrrnmi so weich ausführen, ciaß es merklich zur Federung beiträgt. so Mitte ein solches 1a"er den Nachteil. daß das Rad nicht m;@hr pr;izise geführt. sondern im Raum taumeln würde. 13e1 einer solchen Ausführung wäre der Schwing- arrn nicht wehr nur tint eine Achse drehbar, sondern auch um die Wnrmetrielinie der Schwinge kippbar. Nri seitlichen lielastungcn würde also das Rad nicht mehr rnit dem Hinterrad spuren, sondern aus cler Spur laufen, und zwar so weit, wie (las Rad um die erwähnte `@: ncnretriclinic seitlich kippen kann, was stark von cl<<n Volurncn und der Weichheit des Gummilagers abh:ingig ist. Aufgabe der Erfindung ist es, eine Radaufhängung für die Vordurräder eines Kraftrades zu schaffen, die bei genalter Shttrhalumg den Stößen aus den Fahr@ahn- unebenheiten in Gier jeweiligen Stoßrichtung ausweicht. Die @rfinciurr@ geht aus von einer Vorderradfede- rung eines Kraftrades, hei dem <las Rad an einem etwa waagrecht angeordneten Schwingarm gelagert ist, der von in einem Winkel dazu wirkenden Federteleskopen abgestützt wird, und besteht darin, daß auch der annähernd waagrecht angeordnete Schwingarm zwecks Abfederung des Radlagers in horizontaler Richtung eine Teleskopfederung erhält. Das Spurhalten des Rades beim überrollen von Straßenunebenheiten ist damit gesichert. Zugleich ist dadurch, daß das Rad in einer Ebene ausweichen kann, eine weichere Federung geschaffen und die Neigung zum Verstärken einer durch die Straßcnunel>enheiten angeregten Schwingung verringert.Finally, a front wheel suspension for a motorcycle has been proposed in which the wheel is mounted on an approximately horizontal, rotatably mounted swing arm which is supported by spring telescopes acting at an angle thereto. The swing arm is resiliently mounted in its axis of rotation in a Gunnni bushing. Such a rubber mounting has the `ctrtcil. that they vibrate high frequency, so-called rolling noise. absorbed and makes the bearing maintenance-free. Actual suspension properties over a wide distance, like him for the Damping of shocks from uneven road surfaces is manoeuvrable, but such a rubber mount kiinrlen not be expected. HIM one such camp so spacious and the Gtrrnmi socket so soft perform, ciaß it noticeably contributes to the suspension. so In the middle of such a 1a "he has the disadvantage that the wheel not m; @hr pr; izise led. but stagger in space would. 13e1 of such an embodiment would be the arrn not defend, but rather an axis that can be rotated can also be tilted around the vertical axis of the rocker. The wheel would not therefore have any lateral loads more with the rear wheel, but from the Run the track as far as (read the wheel around the mentioned `@: ncnretriclinic can tilt sideways what strongly influenced by the volume and the softness of the Rubber bearing is dependent. The object of the invention is to provide a wheel suspension for the front wheels of a motorcycle to create the in the case of the old shttrhalumg the shocks from the driving dodges bumps in yaw in the respective direction of thrust. The @ rfinciurr @ is based on a front wheel spring tion of a motorcycle, called the <las wheel on one, for example horizontally arranged swing arm is mounted, the from spring telescopes acting at an angle to it is supported, and consists in the fact that the approximately horizontally arranged swing arm receives a telescopic suspension for the purpose of cushioning the wheel bearing in the horizontal direction. This ensures that the wheel stays in lane when rolling over uneven road surfaces. At the same time, the fact that the wheel can give way in one plane creates a softer suspension and reduces the tendency to intensify an oscillation caused by the speed of the road.

In der Zeichnung ist eilt Ausführungsbeispiel der Erfindung dargestellt. An dem verschieblmr gelagerten lilcskopnthr 6 ist die Radlagerung 2 angelcracht. Das I-eleske>prolir 6 ist irr dem Schwingarm 1 vurschiel>ltar und ;>UM gc- Iagert. In der Britenstabilen Lagerun` 3 ist der Schwingarm an der nach hinten @-e@cn @te,erl;@tpf 4 ah- zweigenden Gabel 7 ,geführt.

Auf die <Wel werden so praktisch alle wirksamen Stöße nur gefedert übertragen, indcrn die UM in Komponenten in Richtung der Teleslkoltfedurutrgce 6 bzw. 5 aufgenonrnren werden. Da diese Federung das Ausweichen des Rades iir einer Ehcne zulä ßt, wä Brend die üblichen Federungen nur das Ausweichen des Rades auf einer Geraden bzw. Kurve ermöglichen, sind die Fahreigcnschaftet des Motorrades damit wesentlicher verbessert.

The drawing shows an exemplary embodiment of the invention. On the sliding head 6 is mounted the wheel bearing 2 angelcracht.
