Description
Die vorliegende Erfindung betrifft ein Rahmenbauteil für einen Zweiradrahmen, insbesondere aus Kunststoff, mit zwei Halbschalen, die stoffschlüssig miteinander verbunden sind. The present invention relates to a frame member for a bicycle frame, in particular made of plastic, with two half shells, which are materially interconnected.
Die vorliegende Erfindung betrifft insbesondere ein Rahmenbauteil für ein Pedelec. Pedelecs unterscheiden sich von einem normalen Fahrrad durch einen zusätzlichen Elektromotor, mindestens ein Batterieelement zum Motorantrieb sowie in der Regel durch eine Steuerelektronik für den Motor. Der Elektromotor des Pedelecs kann zur Unterstützung des Pedalantriebs durch den Fahrer zugeschaltet werden. Die Steuerelektronik misst die aufgewandte Kraft oder die Geschwindigkeit und schaltet bei Erreichen bestimmter Werte den Motor zu- bzw. ab. Die zusätzlichen Elemente eines Pedelecs haben zur Folge, dass das entsprechende Rahmenbauteil vergleichsweise voluminös gestaltet werden muss, um die Versorgungselemente darin unterzubringen. Teilweise werden diese Elemente auch außen am Rahmen befestigt, was jedoch die Optik beeinträchtigt. In der Praxis werden Pedelec-Rahmen häufig manuell gefertigt. The present invention relates in particular to a frame component for a pedelec. Pedelecs differ from a normal bicycle by an additional electric motor, at least one battery element for motor drive and usually by a control electronics for the engine. The electric motor of the pedelec can be switched on to assist the pedal drive by the driver. The control electronics measures the applied force or speed and switches the motor on and off when certain values are reached. The additional elements of a Pedelecs have the consequence that the corresponding frame member must be made comparatively bulky to accommodate the supply elements therein. Some of these elements are also attached to the outside of the frame, but this affects the appearance. In practice pedelec frames are often made manually.
Allgemein werden Fahrradrahmen üblicherweise aus Metallrohren hergestellt. Neben Stahl werden seit einiger Zeit zunehmend auch andere Werkstoffe wie z.B. Aluminium, Titan oder faserverstärkte Kunststoffe verwendet, um das Gewicht des Rahmens zu reduzieren. Die entsprechenden Komponenten werden dann miteinander verschweißt oder verklebt, um die gewünschte Rahmengeometrie zu erhalten. Generally bicycle frames are usually made of metal tubes. In addition to steel, other materials such as e.g. Aluminum, titanium or fiber reinforced plastics used to reduce the weight of the frame. The corresponding components are then welded together or glued together to obtain the desired frame geometry.
Es gab bereits einige Ansätze, Fahrradrahmen aus zwei Halbschalen herzustellen. Ein solcher Rahmen ist beispielsweise in der
Aufgrund der neuen Entwicklungen im Bereich der Elektrofahrräder haben sich die Bedürfnisse und die Anforderungen an ein Fahrrad geändert. Metall eignet sich für Pedelec-Rahmen nur sehr bedingt. Aufgrund der zusätzlichen Versorgungselemente ist es vorteilhaft, eine leichtere Rahmenkonstruktion zu wählen, um das Gesamtgewicht des Fahrrads möglichst gering zu halten. Due to new developments in the field of electric bicycles, the needs and requirements for a bicycle have changed. Metal is only very conditionally suitable for pedelec frames. Due to the additional supply elements, it is advantageous to choose a lighter frame construction in order to keep the total weight of the bicycle as low as possible.
Ein Rahmenbauteil mit den eingangs beschriebenen Merkmalen ist beispielsweise aus der
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, ein Rahmenbauteil mit den eingangs beschriebenen Merkmalen anzugeben, welches eine optimierte stoffschlüssige Verbindung der beiden Halbschalen ermöglicht. Against this background, the invention has for its object to provide a frame member having the features described above, which allows an optimized cohesive connection of the two half-shells.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die beiden Halbschalen im Verbindungsbereich sowohl eine für die Herstellung einer Schweißverbindung geeignete erste Fügegeometrie als auch eine für die Herstellung einer Klebverbindung geeignete zweite Fügegeometrie aufweisen und die beiden Halbschalen sowohl durch mindestens eine Schweißverbindung als auch durch mindestens eine Klebverbindung stoffschlüssig miteinander verbunden sind. Erfindungsgemäß werden also zwei separate, in ihrer Geometrie unterschiedliche, Fügegeometrien vorgesehen. Die Eignung der ersten Fügegeometrie für die Herstellung einer Schweißverbindung liegt insbesondere dann vor, wenn die beiden Halbschalen im Bereich der ersten Fügegeometrie beim Zusammenfügen exakt zueinander positioniert werden und direkt aneinander anliegen, so dass die beiden Halbschalen im Schweißbereich problemlos miteinander verschmelzen können. Beim Fügen mittels Kleben ist es hingegen zweckdienlich, wenn die zweite Fügegeometrie einen gewisser Abstand zwischen den beiden Fügepartnern gewährleistet, so dass der Klebstoff in den daraus resultierenden Spalt zwischen den Halbschalen eingebracht werden kann. This object is achieved in that the two half-shells in the connection area both have a suitable for the production of a weld joint geometry and a suitable for the production of an adhesive joint second geometry and the two half shells by at least one welded joint as well as by at least one adhesive bond are cohesively connected to each other. According to the invention, therefore, two separate joining geometries, which differ in their geometry, are provided. The suitability of the first joining geometry for the production of a welded connection is in particular present when the two half-shells in the region of the first joining geometry during assembly are positioned exactly opposite one another and lie directly against each other, so that the two half-shells can easily merge with one another in the welding area. When joining by gluing, however, it is expedient if the second joining geometry ensures a certain distance between the two joining partners, so that the adhesive can be introduced into the resulting gap between the half-shells.
Es bestehen also grundsätzlich unterschiedliche Anforderungen an die Fügegeometrie, sofern geschweißt oder alternativ geklebt werden soll. Dieser Erkenntnis trägt die Erfindung Rechnung, indem im Verbindungsbereich für beide stoffschlüssigen Fügeverfahren geeignete Fügegeometrien bereitgestellt werden. Vorzugsweise kann wahlweise an jeder Stelle des Fahrradrahmens entschieden werden, ob lokal eine Verschweißung oder ein Verkleben der beiden Halbschalen vorgesehen werden soll. Somit kann stets die an die lokalen Gegebenheiten hinsichtlich Geometrie, thermischer Belastbarkeit, mechanischer Belastung etc. optimal angepasste stoffschlüssige Verbindung vorgesehen werden. So there are basically different demands on the geometry of the joint, if welded or alternatively glued. This finding is taken into account by the invention in the connection area for both cohesive Joining methods suitable joining geometries are provided. Preferably, it can optionally be decided at each point of the bicycle frame, whether locally a welding or gluing the two half-shells to be provided. Thus, it is always possible to provide the material-fit connection optimally adapted to the local conditions with regard to geometry, thermal load capacity, mechanical load, etc.
Zweckmäßigerweise ist die erste Fügegeometrie als eine für eine Laserverschweißung geeignete Presspassung ausgebildet. Presspassung meint in diesem Zusammenhang insbesondere, dass die Geometrien der Halbschalen im Bereich der ersten Fügegeometrie so aufeinander abgestimmt sind, dass durch das Zusammenfügen eine spielfreie Verbindung zwischen den Halbschalen entsteht. Insbesondere liegt durch die Presspassung schon vor dem Schweißvorgang ein fester Verbund zwischen den beiden Halbschalen vor, so dass hierdurch bereits vor dem Schweißvorgang die Fügepartner in vorteilhafterweise ohne weitere Hilfsmittel zueinander exakt positioniert sind. In diesem Fall sind Positionierhilfen, so wie beispielsweise im vorstehend genannten Stand der Technik angegeben, entbehrlich. Zweckmäßigerweise weist die Presspassung eine Breite von 2 bis 8 mm auf. The first joining geometry is expediently designed as a press fit suitable for laser welding. In this context, press-fitting means, in particular, that the geometries of the half-shells in the region of the first joining geometry are coordinated with one another in such a way that a play-free connection between the half-shells is created by the joining together. In particular, by the press fit already before the welding process, a solid bond between the two half-shells, so that in this way before the welding process, the joining partners are positioned in an advantageous manner without further aids to each other exactly. In this case, positioning aids, as indicated for example in the aforementioned prior art, dispensable. Conveniently, the press fit has a width of 2 to 8 mm.
Zweckmäßigerweise weist die zweite Fügegeometrie einen Fügespalt für den Klebstoff auf. Der Fügespalt kann eine Spalthöhe von mindestens 0,1 mm, vorzugsweise mindestens 0,2 mm aufweisen. Ferner beträgt die Breite des Fügespaltes zweckmäßigerweise 1 bis 5 mm. Im Rahmen der Erfindung liegt es in diesem Zusammenhang insbesondere, dass die erste Fügegeometrie derart gestaltet ist, dass sie gleichzeitig eine exakte Positionierung der beiden Halbschalen zueinander für die Klebstoffverbindung im Bereich der zweiten Fügegeometrie gewährleistet. So kann beispielsweise beim Zusammenfügen der beiden Halbschalen in den Bereichen, in denen ein Verkleben zweckmäßig ist, vor dem Zusammenfügen der Halbschalen der Klebstoff aufgetragen werden. Beim Zusammenfügen der beiden Halbschalen wird durch die entsprechende Geometrie der ersten Fügegeometrie eine exakte Positionierung der beiden Halbschalen zueinander erreicht, so dass diese positionsgenau zueinander aushärten können. Durch die partielle Verschweißung der Halbschalen unmittelbar nach deren Zusammenfügen kann in vorteilhafter Weise die exakte Positionierung der Halbschalen zueinander während des Aushärtens des Klebstoffes unterstützt werden. Nach dem Zusammenfügen der beiden Halbschalen werden entsprechend die Bereiche, in denen eine Verschweißung, insbesondere eine Laserverschweißung, vorteilhaft ist, miteinander verschweißt, während die anderen Bereiche miteinander verklebt werden. In diesem verschweißten Zustand kann dann eine vollständige Aushärtung der miteinander verbundenen Halbschalen im Bereich der Klebstoffverbindung erfolgen. The second joining geometry expediently has a joint gap for the adhesive. The joint gap may have a gap height of at least 0.1 mm, preferably at least 0.2 mm. Furthermore, the width of the joint gap is expediently 1 to 5 mm. In the context of the invention it is in this context in particular that the first joining geometry is designed such that it simultaneously ensures an exact positioning of the two half-shells to each other for the adhesive connection in the region of the second joining geometry. Thus, for example, when joining the two half-shells in the areas in which bonding is expedient, the adhesive is applied before the half-shells are joined together. When joining the two half-shells an exact positioning of the two half-shells is achieved to each other by the corresponding geometry of the first joining geometry, so that they can cure to each other positionally accurate. Due to the partial welding of the half shells immediately after their assembly, the exact positioning of the half shells relative to one another during the curing of the adhesive can be advantageously supported. After joining the two half-shells, the regions in which welding, in particular laser welding, is advantageous, are welded together, while the other regions are glued together. In this welded state, complete curing of the interconnected half-shells in the area of the adhesive connection can take place.
Im Rahmen der Erfindung liegt es insbesondere, dass die Halbschalen entlang ihres Umfangs abwechselnd lediglich miteinander verschweißt bzw. lediglich miteinander verklebt sind. Insbesondere kann hierbei in den Übergangsbereichen zwischen Kleb- und Schweißverbindung eine doppelte stoffschlüssige Verbindung vorliegen, also das Ende der Schweißnaht sich mit dem Beginn der Klebstoffverbindung überlappen und umgekehrt. Diese Überlappungsbereiche können beispielsweise eine Länge von 2 bis 10 mm aufweisen. In the context of the invention, it is particularly the case that the half-shells are alternately merely welded together or glued together only along their circumference. In particular, a double cohesive connection may be present in the transition regions between the adhesive and welded connection, that is, the end of the weld overlaps with the beginning of the adhesive connection and vice versa. These overlapping areas may, for example, have a length of 2 to 10 mm.
Im Rahmen der Erfindung liegt es, dass der Verbindungsbereich durch innere Rippen an mindestens einer Halbschale mechanisch stabilisiert ist. Insbesondere können die erste Fügegeometrie und die zweite Fügegeometrie unmittelbar nebeneinander angeordnet sein, vorzugsweise stufenartig nebeneinander. Ferner können die erste und / oder die zweite Fügegeometrie zumindest bereichsweise an den Halbschalen umlaufend angeordnet sein. Abgesehen von konstruktiv bedingten Unterbrechungen, wie beispielsweise Aufnahme für Lenker, Fahrersattel oder dergleichen, können die beiden Fügegeometrien insbesondere vollständig umlaufend an den Halbschalen vorgesehen sein. In the context of the invention, it is the case that the connection region is mechanically stabilized by inner ribs on at least one half shell. In particular, the first joining geometry and the second joining geometry can be arranged directly next to one another, preferably in a stepwise manner next to one another. Furthermore, the first and / or the second joining geometry can be arranged circumferentially on the half shells at least in regions. Apart from design-related interruptions, such as recording for handlebars, driver's saddle or the like, the two joining geometries can be provided in particular completely circumferentially on the half shells.
Zweckmäßigerweise bildet eine Halbschale die Innengeometrie beider Fügegeometrien und die andere Halbschale die Außengeometrie beider Fügegeometrien. Vorzugsweise sind die beiden Fügegeometrien im äußeren Randbereich der beiden Halbschalen angeordnet. Wie bereits erwähnt, können die Halbschalen Aufnahmen für einen Lenker und / oder ein Tretlager und / oder einen Fahrersattel bilden. Conveniently, one half-shell forms the inner geometry of both joining geometries and the other half-shell forms the outer geometry of both joining geometries. Preferably, the two joining geometries are arranged in the outer edge region of the two half-shells. As already mentioned, the half-shells can form receptacles for a handlebar and / or a bottom bracket and / or a driver's seat.
