Die als Lagerstelle vorgesehenen Bolzen werden üblicherweise als separate Bauteile hergestellt und in einem zusätzlichen Arbeitsgang nach Herstellung des Lenkerkörpers mit diesem beispielsweise durch Verschweißen verbunden. Eine derartige Herstellungsweise ist naturgemäß mit mehreren unterschiedlichen Arbeitsabläufen verbunden und somit zeit- und damit kostenintensiv.such Trailing arm are also referred to as wishbones and usually consist of at least one of a sheet metal part molded upper shell and at least one lower shell formed from a sheet metal part, in their edge areas - for example joined by welding -, one Hollow body the so-called handlebar body form. The handlebar body It has articulation points for fixing wheel-related components as well about that In addition, articulation points for body-side determination of the guide arm. The articulation points are usually designed so that in them one certain mobility guaranteed is that by an elastic storage, for example by means of Rubber elements is realized. These rubber elements can on Trailing arm in circular receiving sockets be included, about it In addition, from the prior art constructions are known in which pin-shaped over the actual handlebar body protruding bolts for receiving rubber elements - such as Rubber bearing rings - provided are. The intended as a bearing pin bolts are usually manufactured as separate components and in an additional Operation after production of the handlebar body with this example by welding connected. Such a method of preparation is naturally with several connected to different work processes and thus time-consuming and thus cost-intensive.
Darüber hinaus sind bezüglich der Anbindungsstellen an die genannten Lenkerkörper Lösungen bekannt geworden, bei denen an den Lagerstellen der Lenkerkörper zur Karosserie spezielle Gummielemente eingesetzt werden, die ringförmig ausgestaltet sind, wobei die Innengeometrie des Bauteils sechskantig ausgeführt ist. Durch diese spezielle Bauweise sollen Verdrehungen des Gummielementes in der Lagerstelle des Lenkerkörpers vermieden werden.Furthermore are re the connection points to said handlebar body solutions become known at those at the bearing points of the handlebar body to the body special Rubber elements are used, which are designed annular, wherein the internal geometry of the component is hexagonal. Due to this special construction should distortions of the rubber element in the bearing of the handlebar body be avoided.
