Description

Rohrverriegelung im Steuerkopf von Kraftrad-Doppelrohrrahmen. Erfahrungsgemäß ist bei Motorradrahmen das den Motor tragende untere Rahmenrohr hoch beansprucht, weshalb manche Unterrahmen als Doppelrohrrahmen ausgebildet sind. Allgemein werden diese Doppelrohre in einem sogenannten Steuerkopf in Muffen geführt, wo sie verlötet oder eingeschweißt werden.Tube lock in the steering head of a motorcycle double tube frame. According to experience on motorcycle frames, the lower frame tube supporting the engine is highly stressed, which is why some subframes are designed as double tubular frames. Become general these double pipes are guided in a so-called control head in sleeves, where they are soldered or welded.

Eine derartige Verbindung birgt eine große Gefahrmöglichkeit in sich, weil gerade am Steuerkopf besonders große Kräfte während des Fahrbetriebes auftreten; schwere Stürze sind dadurch öfters entstanden, daß die unteren Tragrohre sich aus den Muffen des Steuerkopfes gelöst haben, wenn sie nicht infolge schlechten Materials oder falscher Abmessungen überhaupt brachen.Such a connection harbors a great danger, because especially large forces occur on the steering head during driving; Serious falls are often caused by the fact that the lower support tubes come off have loosened the sleeves of the control head if they are not due to poor material or wrong dimensions broke at all.

Das unbeabsichtigte Loslösen der Tragrohre wird nun durch die im folgenden beschriebene Erfindung unmöglich gemacht.The unintentional detachment of the support tubes is now caused by the following described invention made impossible.

Die beiden schrägen Tragrohre B haben an ihrem Kopf eine Aussparung o, deren Radius gleich ist dem Radius des Querschnittes des unteren Tanktragrohres A. Auf den beiden Muffenstutzen b, die zur Einführung der Tragrohre B dienen, sitzt in der senkrechten Mittelebene die Muffe a, und zwar so, daß es möglich ist, das Tanktragrohr A durch die Muffe a in die Aussparung o der beiden Tragrohre zu schieben. Sobald das Tanktragrohr A in den Sitz o eingepreßt ist, sind die Tragrohre B verriegelt; sie können dann weder einzeln noch zusammen aus dem 'Steuerkopf S herausgleiten, gleichgültig, ab dann die Tragrohre mit dem Steuerkopf S durch Lotung oder Verschweißung verbunden sind oder nicht.The two inclined support tubes B have a recess on their head o, the radius of which is equal to the radius of the cross section of the lower tank support pipe A. Sitting on the two socket nozzles b, which are used to introduce the support tubes B. in the vertical center plane the sleeve a, in such a way that it is possible that Push the tank support pipe A through the socket a into the recess o of the two support pipes. As soon as the tank support pipe A is pressed into the seat o, the support pipes B are locked; they can then slide out of the control head S neither individually nor together, indifferent, from then on the support tubes with the control head S by soldering or welding connected or not.
