Description
Teleskopfederbein, insbesondere für Mopeds Die Erfindung betrifft ein Teleskopfederbein, insbesondere für Mopeds, bei dem innerhalb von Teleskoprohren eine Schraubenfeder angeordnet und diese mit den Teleskoprohren zugsicher verbunden ist. Derartige Federbeine nehmen im allgemeinen nur Druckkräfte auf, müssen jedoch bei besonderen Fahrzuständen, z. B, wenn das Rad des Mopeds vollkommen ausfedert, Zugkräfte aufnehmen. Es ist bekannt, zu diesem Zwecke die beiden Enden der Schraubenfeder in der Schraubensteigung entsprechende Nuten von besonderen Teilen einzudrehen, die mit den Teleskoprohren verbunden sind. Für die Herstellung dieser mit Nuten versehenen Teile und für die Verbindung derselben mit den Teleskoprohren ist ein besonderer Aufwand erforderlich, der für den angegebenen Zweck bei einer Massenfertigung verhältnismäßig groß ist.Telescopic strut, particularly for mopeds The invention relates a telescopic shock absorber, especially for mopeds, in which telescopic tubes are used arranged a coil spring and this connected to the telescopic tubes in a tensile manner is. Such struts generally only absorb compressive forces, but must in special driving conditions, e.g. B, when the wheel of the moped rebounds completely, Absorb tensile forces. It is known to use the two ends of the helical spring for this purpose to screw in corresponding grooves in the screw pitch of special parts, which are connected to the telescopic tubes. For making these with grooves provided parts and for the connection of the same with the telescopic tubes is a special effort required for the stated purpose in mass production is relatively large.
Das Teleskopfederbein gemäß der Erfindung ist dadurch gekennzeichnet, daß in dem Spalt zwischen der Innenwand der Teleskoprohre und dem Außendurchmesser der Schraubenfeder ein verformbarer Ring eingelegt ist, der zwischen die Federgänge gepreßt wird, indem am äußeren Umfang der Teleskoprohre eine Sicke eingedrückt wird. Auf diese Weise wird eine einwandfreie zugsichere Verbindung zwischen den Federenden und dem Teleskoprohr hergestellt und dafür ein fertigungsmäßig sehr geringer Aufwand benötigt. Die Sickennuten können dabei mit oder ohne Steigung ausgeführt sein.The telescopic strut according to the invention is characterized in that in the gap between the inner wall of the telescopic tubes and the outer diameter the helical spring a deformable ring is inserted between the spring coils is pressed by pressing a bead on the outer circumference of the telescopic tubes. In this way, there is a flawless, secure connection between the spring ends and the telescopic tube and therefor a very little effort in terms of production needed. The bead grooves can be designed with or without a slope.
Ein Ausführungsbeispiel des Teleskopfederbeines gemäß der Erfindung ist in der Zeichnung dargestellt. Das Teleskopfederbein besteht aus dem unteren Teleskoprohr 1, dem oberen Teleskoprohr 2, der Schraubenfeder 3 und den Befestigungsaugen 4. Zwischen den Enden der Schraubenfeder 3 und den Teleskoprohren 1 bzw. 2 sind die erfindungsgemäßen Ringe 5 bzw. 6 angeordnet, :deren Material sich durch das Eindrücken der Sickernuten 7 bzw. 8 zwischen die Federendwindungen setzt.An embodiment of the telescopic strut according to the invention is shown in the drawing. The telescopic strut consists of the lower one Telescopic tube 1, the upper telescopic tube 2, the coil spring 3 and the fastening eyes 4. Between the ends of the coil spring 3 and the telescopic tubes 1 and 2 respectively the rings according to the invention 5 or 6 arranged, whose material is characterized by the Pressing in the seepage grooves 7 or 8 between the spring end windings sets.
Die Erfindung ist nicht auf das gezeichnete Ausführungsbeispiel beschränkt. Insbesondere können die Federendwindungen :beliebig ausgebildet, z. B. können mehrere anliegende Windungen vorgesehen sein. Als Material der Zwischenringe kommt jedes verformbare Material auf Metall- oder Kunststoffbasis in Frage, das die entsprechenden Zugkräfte mit Sicherheit aufnehmen kann.The invention is not limited to the illustrated embodiment. In particular, the spring end windings can be designed as desired, e.g. B. can be several adjacent turns may be provided. Any type of material can be used for the intermediate rings deformable metal or plastic-based material in question, which is the corresponding Can absorb tensile forces with certainty.
