Description

Hinterradfederung. Es gibt schon verschiedene Hinterradfederungen sowohl an Motor- als auch an motorlosen Rädern, um die auftretenden Stöße, welche von Straßenunebenheiten hervorgerufen werden, zu mildern.Rear suspension. There are already different rear suspension systems both on motorcycles and on motorless bikes, in order to avoid the impacts occurring, which caused by bumps in the road.

Der Gegenstand der vorliegenden Erfindung stellt eine Hinterradfedereinrichtung dar, bei der zwei Zugfedern und eine Stoßfeder in Anwendung kommen, von denen die beiden ersteren einerends an festen Rahmenpunkten und andernends an verstellbaren Punkten an einem an den Rahmen dreh- und schwingbaren Hebel angehängt sind, und zwar derart, daß eine dieser - Federn kprz vor ihrer Endspannung durch eine an einer zwischen der unteren und der schräg nach oben führenden Hinterradgabel vorgesehenen Strebe angebrachten Anschlagnase ihre Wirkungsfähigkeit in bezug auf den schwingbaren Tragarm verliert. Die als Aufschlagfeder wirkende Stoßfeder verhindert das Durchstrecken der beiden vorerwähnten Zugfedern bei größeren Ausschlägen nach unten.The object of the present invention provides a rear wheel spring device represents, in which two tension springs and a shock spring are used, of which the the former at one end at fixed frame points and at the other at adjustable ones Points are attached to a pivotable and pivotable lever on the frame, and in such a way that one of these - springs kprz before their final tension by one on one provided between the lower and the obliquely upward rear fork Strut attached stop nose their effectiveness in relation to the swingable Support arm loses. The shock spring, which acts as an impact spring, prevents it from stretching of the two aforementioned tension springs with larger deflections downwards.

Auf der Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsform zur Darstellung gebracht. Es zeigt Abb. i eine Seitenansicht der Federung, Abb. z den unteren Teil der Strebe mit Anschlagnase.The subject of the invention is shown in an exemplary manner in the drawing Embodiment brought to the display. It shows Fig. I a side view of the Suspension, Fig. Z the lower part of the strut with stop lug.

Nach der Zeichnung bedeutet a einen schwingbaren, am hinteren Fahrradrahmen bei a1 drehbaren Tragarm. Die beiden Federn b und bi sind an den oberen Enden bei; c und und cl und an ihren unteren Enden bei d und dl aufgehängt. Die Verstrebung e ist fest an den Rahmenbau angeordnet und besitzt einen Ausschnitt/, welcher als Führung für den schwingbaren Tragarm a dient. Der Teil e besitzt ferner eine Anschlagnase e1, welche den Zweck hat, daß die Feder b1 in bezug auf den Tragarm a ihre Zugkraft ausschaltet, wodurch die Massenbewegung eine Verzögerung erleidet, und somit eine sanfte Endspannung, die der Feder b allein überlassen wird, eintritt. Die Feder g ist einerseits an dein schwingbaren Tragarm a befestigt und hat den Zweck, starke Durchschläge nach unten zu verhindern. Die beiden Aufhängpunkted und dl können je nach dem Gewicht des Fahrers in größere oder kleinere Entfernungen in bezug auf den Drehpunkt a1 versetzt werden. h bedeutet die Achse des Hinterrades.According to the drawing, a means one swingable, on the rear bicycle frame at a1 rotating support arm. The two springs b and bi are at the upper ends at; c and and cl and suspended at their lower ends at d and dl. The strut e is fixed to the frame structure and has a cutout /, which serves as a guide for the swingable support arm a. Part e also has a stop lug e1, which has the purpose that the spring b1 with respect to the support arm a switches off its pulling force, whereby the mass movement suffers a delay, and thus a gentle final tension, which is left to the spring b alone, occurs. The spring g is attached on the one hand to your swingable arm a and has the Purpose to prevent strong punctures to the bottom. The two suspension points and dl can be used in greater or lesser distances depending on the weight of the driver be offset with respect to the pivot point a1. h means the axis of the rear wheel.

PATENTANSPRUCH: Hinterradfederung, gekennzeichnet durch zwei Zugfedern (b, bl) und eine Stoßfeder (g), von denen die beiden ersteren einerends an festen Rahmenpunkten (c, cl) und andernends an verstellbaren Punkten (d, dl) an einem an den Rahmen dreh- und schwingbaren Tragarm (a) angehängt sind, derart, daß die Feder (b1) kurz vor ihrer Endspannung durch eine Anschlagnase (e1) ihre Wirkungsfähigkeit in bezug auf den schwingbaren Tragarm (a) verliert, während die Stoßfeder (g) als Aufschlagfeder wirkt, so daß das Durchstrecken der beiden vorerwähnten Zugfedern bei größeren Ausschlägen nach unten verhindert wird. PATENT CLAIM: Rear suspension, characterized by two tension springs (b, bl) and a shock spring (g), the first two of which rotate at one end at fixed frame points (c, cl) and at the other end at adjustable points (d, dl) on one of the frame - and swingable support arm (a) are attached in such a way that the spring (b1) loses its effectiveness in relation to the swingable support arm (a) shortly before its final tension due to a stop lug (e1), while the shock spring (g) acts as an impact spring , so that the stretching of the two aforementioned tension springs is prevented in the event of larger downward deflections.
