Abstract
Description
Die Erfindung bezieht sich auf eine Radfelge, insbesondere auf eine Fahrradfelge.The The invention relates to a wheel rim, in particular to a Bicycle rim.
Das US Patent Nr. 6,817,680 B2 offenbart eine herkömmliche Fahrradfelge mit zwei einander gegenüber liegenden Felgenflanken, die einen Abstand zueinander haben und die jeweils eine horizontal liegende Felgenachse umschließen. Jede der Felgenflanken hat eine radial innen liegende Kante und eine radial außen liegende Kante zum Halten des Reifens. Die herkömmliche Radfelge umfasst ferner einen Felgenboden, der die radial innen liegenden Kanten der Felgenflanken miteinander verbindet, wobei eine kranzförmige Verstärkungswand die Felgenflanken verbindet und den Felgenboden umschließt, und zwei einander gegenüberliegende kranzförmige Verbindungswände, welche den Felgenboden und die kranzförmige Verstärkungswand verbinden. Eine Mehrzahl von Befestigungskomponenten für Speichen erstreckt sich durch den Felgenboden hindurch und ist zwischen den kranzförmigen Verbindungswänden angeordnet. Aufgrund der kranzförmigen Verbindungswände wird die Festigkeit der herkömmlichen Radfelge verstärkt. Da jedoch der Felgenboden und die kranzförmige Verstärkungswand als Kreisbögen geformt sind, die sich von der Felgenachse weg öffnen, kann sich die herkömmliche Radfelge unter der Beaufschlagung einer seitlich gerichteten Stoßkraft verformen. Der Nachteil ist sehr gravierend, wenn die herkömmliche Radfelge für Extremsportgeräte verwendet wird, die eine Radfelge mit einem relativ breiten und flachen radialen Querschnitt benötigen, wie beispielsweise BMX-Räder und Mountainbikes.The US Pat. No. 6,817,680 B2 discloses a conventional bicycle rim with two opposite each other lying rim flanks, which have a distance from each other and each enclosing a horizontal rim axis. each the rim flanks has a radially inner edge and a radially outside lying edge for holding the tire. The conventional wheel rim further includes a Rim bottom, which is the radially inner edges of the rim flanks connects to each other, wherein a coronal reinforcing wall, the rim flanks connects and surrounds the rim floor, and two opposite each other coronal connecting walls, which the rim base and the coronal reinforcing wall connect. A plurality of fastening components for spokes extends through the rim bottom and is between the annular connecting walls arranged. Due to the coronal connecting walls will the strength of conventional Wheel rim reinforced. However, since the rim base and the corrugated reinforcing wall are formed as circular arcs which open away from the rim axis, the conventional Deform wheel rim under the action of a laterally directed impact force. The disadvantage is very serious when the conventional wheel rim is used for extreme sports equipment being a wheel rim with a relatively wide and flat radial Need cross section, such as BMX wheels and mountain bikes.
Eine weitere herkömmliche, im US Patent Nr. 6,817,680 B2 offenbarte Fahrradfelge umfasst ein Paar einander gegenüberliegende Felgenflanken, die einen Abstand zueinander haben und die jeweils eine horizontal liegende Felgenachse umschließen. Diese herkömmliche Radfelge umfasst ferner einen Felgenbogen, der radial innen liegende Kanten der Felgenflanken miteinander verbinden, ein Paar kranz förmige Verstärkungswände und eine angewinkelte Kranzwand. Jede der kranzförmigen Verstärkungswände ist mit einer Kante mit dem Felgenboden verbunden und ist mit einer weiteren Kante mit jeweils einer der Felgenflanken verbunden. Die angewinkelte Kranzwand umfasst einen gebogenen Bereich und ein Paar schräger Bereiche, die sich schräg von gegenüberliegenden Kanten des gebogenen Bereichs zu dem Felgenboden erstrecken. Die Befestigungskomponenten für die Speichen erstrecken sich durch den Felgenboden hindurch und sind zwischen jeweils einer der kranzförmigen Verstärkungswände und einem korrespondierenden schrägen Bereich der angewinkelten Kranzwand angeordnet.A other conventional, The bicycle rim disclosed in US Pat. No. 6,817,680 B2 comprises a pair opposite each other Rim flanks, which have a distance to each other and each one enclose horizontal rim axis. This conventional Wheel rim also includes a rim arc, the radially inner Connect edges of the rim edges together, a pair of wreath-shaped reinforcement walls and an angled wreath wall. Each of the coronal reinforcing walls is connected with one edge to the rim bottom and is with a further edge connected to one of the rim flanks. The angled rim wall includes a curved portion and a pair oblique Areas that are sloping from opposite Extend edges of the bent portion to the rim bottom. The fastening components for the Spokes extend through the rim floor and are in between each one of the coronal Reinforcement walls and a corresponding oblique Area of the angled crown wall arranged.
Aufgrund der angewinkelten Kranzwand wird die Festigkeit des Felgenbodens verstärkt. Da sich jedoch Belastungskräfte, die auf die angewinkelte Kranzwand ausgeübt werden, an dem gebogenen Bereich konzentrieren und da die angewinkelte Kranzwand mit dem Felgenboden verbunden ist, verformt sich diese herkömmliche Radfelge auch sehr leicht beim Aufbringen einer seitlichen Druckkraft. Wie bei der vorherigen herkömmlichen Radfelge ist der Nachteil sehr gravierend, wenn diese herkömmliche Radfelge einen relativ breiten und flachen radialen Querschnitt haben soll.by virtue of the angled rim wall becomes the strength of the rim floor strengthened. However, as stressors, which are applied to the angled rim wall, at the curved portion concentrate and there the angled cornice wall with the rim bottom is connected, deforms this conventional wheel rim also very easily when applying a lateral compressive force. As with the previous one usual Wheel rim, the disadvantage is very serious, if this conventional Wheel rim a relatively wide and flat radial cross-section should have.
Deshalb ist die Aufgabe der vorliegenden Erfindung, eine Radfelge zu schaffen, die eine solide und leichte Konstruktion hat.Therefore the object of the present invention is to provide a wheel rim, which has a solid and lightweight construction.
Demgemäß umfasst eine Radfelge der vorliegenden Erfindung einen Felgenboden mit einer horizontal verlaufenden Felgenachse und einer gedachten Mittelebene, die senkrecht zur Felgenachse verläuft. Der Felgenkörper umfasst zwei Felgenflanken, einen Felgenboden, zwei kranzförmige Stabilisierungswände und eine kranzförmige Verstärkungswand. Die Felgenflanken sind jeweils auf gegenüberliegenden Seiten der gedachten Mittelebene angeordnet und umschließen die Felgenachse. Der Felgenboden verbindet die Felgenflanken. Jede der kranzförmigen Stabilisierungswände erstreckt sich von jeweils einer der Felgenflanken zu der gedachten Mittelebene und ist relativ zu dem Felgenboden radial außen angeordnet. Die Verstärkungswand umfasst zwei Verbindungssegmente, die jeweils den Felgenboden und jeweils eine der kranzförmigen Stabilisierungswände verbindet, und ein vorstehendes Verstärkungssegment, das die Verbindungssegmente verbindet und das relativ zur Felgenachse radial nach außen vorsteht.Accordingly, includes a wheel rim of the present invention, a rim base with a horizontally extending rim axis and an imaginary center plane, which runs perpendicular to the rim axis. The rim body comprises two rim flanks, a rim base, two coronal stabilization walls and a coronal one Reinforcing wall. The rim flanks are each on opposite sides of the imaginary Center plane arranged and enclose the rim axis. The rim bottom connects the rim flanks. Each of the coronal stabilization walls extends from one of the rim flanks to the imaginary center plane and is disposed radially outward relative to the rim bottom. The reinforcement wall comprises two Connecting segments, each of the rim base and one each the coronal one stabilizing walls connects, and a projecting reinforcing segment that connects the connecting segments and projecting radially outward relative to the rim axis.
