Description
Rahmenverstelfung von Fahrrädern mit hiiiismotoren. Fahrrad-Hilfsmotoren, die am Rahmen befestigt werden, sind gewöhnlieh mit den <B>Z=</B> einzelnen Rahmenrohren durch Klemmen verbunden.
Die starre Verbindung des No- torgehäuses mit dem Rahmen des Fahrracles hat den Nachteil, dass die durch die hohe Drehzahl<B>'</B> hervorgerufenen Erschütterungen des Motors auf den Ral#men des Fahrzeuges übertrao,en werden und hierdureh Beschädi gungen der Rahmenrohre hervorgerufen n <B>in</B> werden können. Die Erfindung bezweckt, kD diesen Übelstand zu vermindern.
Der Erfindungsgegenstand zeichnet sieh dadurch aus, dass die Befestigung des Motors ZD nicht unmittelbar am Falirzeugrahmen er folgt, sondern unter Zwischensehaltung eines oder mehrerer Zwischenrohrstüc-ke, von denen jedes zwechmässigerweise zweiteilig ausgebil det ist, um die Montage zu erleichtern.
Bei der Verwendung mehrerer Rohrstücke sind diese übereinander anzuordnen.
Der Erfindungsgegenstand ist auf bei liegender Zeichnung in einer beispielsweisen Ausfülirungsforin veranschaulicht. Der Motor, der bei dem dargestellten Bei spiel unterhalb des Fahrzeugrahmens ange ordnet ist, wird an dem schrägen Rahmen rohr a mittelst einer Klemme<B>b</B> befestigt. Um eine Versteifung des Rahmenrohres zu erreichen, sind-zwisclien Rahmenrohr a und Klamme <B>b</B> mehrere (zwei) durch Teilung in ihrer Längsriehtung zweiteilig ausgebildete Rohrstücke c gelegt, die einerseits durch die Motorbefestigung festgeklemmt werden. Die andern Endteile der verschieden lancen Rohr stücke sind durch eine Rohrschelle<B>d</B> zu sammengehalten.
Diese Versteifung kann an jeder Stelle des Fahrradrahmens entsprecliend der Lage des Motors ankebracht werden.
Statt der dargestellten zwei RohrstÜcke c können noch mehr Anwendung finden; es kann aber auch nur ein einziges Rohrstück zwischengeschaltet werden.

Frame adjustment of bicycles with hi-fi engines. Bicycle auxiliary motors that are attached to the frame are usually connected to the <B> Z = </B> individual frame tubes by clamps.
The rigid connection of the notor housing with the frame of the bicycle has the disadvantage that the vibrations of the engine caused by the high speed are transmitted to the frame of the vehicle and, as a result, damage to the Frame tubes can be caused n <B> in </B>. The invention aims to reduce this drawback.
The subject of the invention is characterized by the fact that the motor ZD is not attached directly to the aircraft frame, but with one or more intermediate pipe pieces in between, each of which is designed in two parts to facilitate assembly.
When using several pipe sections, these must be arranged one above the other.
The subject of the invention is illustrated in an exemplary Ausfülirungsforin in the accompanying drawing. The motor, which is arranged in the example shown below the vehicle frame is attached to the inclined frame tube a by means of a clamp <B> b </B>. In order to stiffen the frame tube, between frame tube a and clamp <B> b </B> several (two) two-part tube pieces c formed by dividing in their longitudinal direction are placed, which are clamped on the one hand by the motor mount. The other end parts of the different lengths of pipe are held together by a pipe clip <B> d </B>.
This stiffener can be attached at any point on the bicycle frame according to the position of the motor.
Instead of the two pipe sections c shown, even more applications can be used; but only a single piece of pipe can be interposed.
