Die Erfindung betrifft eine Speiche aus einem Drahtabschnitt für das Rad eines Zweirades.The invention relates to a spoke made of a wire section for the wheel of a two-wheeler.
Es ist bekannt, eine Speiche aus Stahl oder rostfreiem Stahl herzustellen. Die Speiche aus Stahl weist eine höhere Schwingfestigkeit als die aus rostfreiem Stahl auf, besitzt aber hierbei den Nachteil, daß die Speiche rostet. Um dies zu vermeiden, ist es bekannt, die Speiche aus Stahl zu verzinken oder zu verchromen. Die verzinkte oder verchromte Oberfläche ist anfällig gegen mechanische Beschädigungen, so daß sie leicht den Oberflächenschutz verliert. Hierdurch werden die mechanischen Eigenschaften der Speiche und das äußere Bild beeinträchtigt.It is known to manufacture a spoke from steel or stainless steel. The steel spoke has a higher vibration resistance than the stainless steel one, but has the disadvantage that the spoke rusts. To avoid this, it is known to galvanize or chrome-plate the steel spoke. The galvanized or chrome-plated surface is susceptible to mechanical damage, so that it easily loses its surface protection. This affects the mechanical properties of the spoke and its external appearance.
Aufgabe der Erfindung ist es, eine Speiche des Rades so zu verbessern, daß sie bei einem besseren Oberflächenschutz eine hohe Schwingfestigkeit besitzt.The object of the invention is to improve a spoke of the wheel so that it has a high vibration resistance with better surface protection.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Drahtabschnitt ein Verbunddraht ist mit einem Kerndraht, der von einer plattierten, korrosionsbeständigen Schicht außen umgeben ist.This object is achieved according to the invention in that the wire section is a composite wire with a core wire which is surrounded on the outside by a plated, corrosion-resistant layer.

Eine solche Speiche besitzt die hohe Schwingfähigkeit von Stahl und ist darüber hinaus korrosionsbeständig und alterungsbeständig.Such a spoke has the high vibration capacity of steel and is also corrosion-resistant and age-resistant.
Diese Schicht ist mechanisch aufgebracht.This layer is applied mechanically.
In vorteilhaften Ausführungen wird vorgeschlagen, daß der Kerndraht aus Stahl besteht und die Schicht aus Edelstahl, Titan, einer Titanlegierung oder aus Aluminium. Alternativ kann aber auch vorteilhafterweise der Kerndraht aus Carbonfasern bestehen oder Carbonfasern aufweisen und die Schicht aus Stahl, Edelstahl, Titan oder einer Titanlegierung bestehen.In advantageous embodiments, it is proposed that the core wire is made of steel and the layer is made of stainless steel, titanium, a titanium alloy or aluminum. Alternatively, the core wire can also advantageously consist of carbon fibers or have carbon fibers and the layer is made of steel, stainless steel, titanium or a titanium alloy.
Ausführungsbeispiele der Erfindung werden im folgenden näher beschrieben.Embodiments of the invention are described in more detail below.
Die Speiche besteht aus einem Drahtabschnitt, dessen an der Radnabe befestigtes Ende meist umgebogen ist und einen verdickten Kopf aufweist. Die Speiche ist auf Zugbeanspruchung vorgespannt.The spoke consists of a section of wire, the end of which is attached to the wheel hub and is usually bent and has a thickened head. The spoke is pre-tensioned to withstand tensile stress.
Der Drahtabschnitt ist ein Verbunddraht mit einem Kerndraht, der aus Stahl besteht. Stahl besitzt eine hohe Schwingfestigkeit. Außen ist der Kerndraht von einer korrosionsbeständigen Schicht umgeben, die durch Plattieren hergestellt ist. Hierbei wird eine mechanische Ummantelung bevorzugt. Die plattierte Schicht besteht aus Edelstahl, Titan, einer Titanlegierung oder aus Aluminium.The wire section is a composite wire with a core wire made of steel. Steel has a high fatigue strength. The core wire is surrounded on the outside by a corrosion-resistant layer made by plating. A mechanical coating is preferred here. The plated layer is made of stainless steel, titanium, a titanium alloy or aluminum.
In einer weiteren alternativen Ausführung besteht der Kerndraht aus Carbonfaser(n) und ist außen mit einer Schicht aus Stahl, Edelstahl, Titan oder einer Titanlegierung versehen.In another alternative design, the core wire is made of carbon fiber(s) and is provided on the outside with a layer of steel, stainless steel, titanium or a titanium alloy.
