Abstract

In the case of bicycle spoked road wheels of a conventional design wire spokes are used which have a head bent at right angles and which are clamped in the road wheel via loosely screwed-on spoke nipples. The right-angled bend in the spoke has a tendency to tear under a sustained loading, the spoke nipples can be loosened by vibrations occurring during operation and the true running of the road wheel is hence impaired. The advantages obtained with the invention consist in that the spoke (1), which has a fixedly connected spoke nipple (2) which is designed as a hexagon and hence can be rotated from the outer side of the rim (3), is screwed as a whole directly into the threaded hole (5) in the hub body (4) thus dispensing with the bend in the spoke. By virtue of the fixed locking to the hub body by means of the lock nut (6) screwed onto the spoke thread the spoke is protected under all load influences against the screwed connection becoming loose. The spokes are particularly suitable for bicycle road wheels which are exposed to high loads, for example, for competitive purposes. <IMAGE>

Description

Bei Fahrradspeichenlaufrädern herkömmlicher Art werden Felge und Nabe durch Drahtspeichen verbunden, deren eines Ende rechtwinklig abgebogen und mit einem aufgestauchten Kopf versehen ist. Das andere Ende besitzt ein Gewinde, auf das der Speichennippel aufgeschraubt werden kann. Die Verbindung mit der Nabe erfolgt dadurch, daß die Speiche mit ihrem Kopf in die an den beiden Nabenflanschen befindlichen, parallel zur Nabenachse eingestellten Bohrungen eingehängt werden. Das freie Speichenende wird in eine radial eingestellte Bohrung der Felge gesteckt, und von der Gegenseite her der Speichennippel aufgeschraubt, dessen Durchmesser größer als derjenige der Felgenbohrung ist. Mittels dieser Speichennippel können die Speichen gespannt werden und die Felge zentriert.In conventional bicycle spoke wheels, the rim and hub are separated by wire spokes connected, one end of which is bent at right angles and provided with an upturned head is. The other end has a thread on which the spoke nipple can be screwed. The connection to the hub takes place in that the spoke with its head in the to the bores located in both hub flanges and set parallel to the hub axis become. The free end of the spoke is inserted into a radially set hole in the rim, and screwed on from the opposite side the spoke nipple, the diameter of which is larger than that the rim hole is. By means of this spoke nipple the spokes can be tensioned and centered the rim.

Das Problem bei dieser Konstruktion liegt in der mangelhaften Dauerhaftigkeit. Der rechtwinklige Speichenbogen am Nabenflansch neigt dazu, sich unter starker Belastung aufzuziehen und nach längerer Dauerbeanspruchung zu reißen. Der Speichennippel ist nur durch die Speichenvorspannung arretiert. Unter Betriebseinflüssen wie Stößen und Schwingungen neigt der Speichennippel dazu, sich zu lösen, so daß der Rundlauf des Rades beeinträchtigt und ein Nachzentrieren notwendig wird.The problem with this construction is the poor durability. The right angle Spoke arch on the hub flange tends to wind up and under heavy load long-term stress. The spoke nipple is only through the Spoke preload locked. It tends to be affected by operational influences such as shocks and vibrations Spoke nipples to loosen so that the concentricity of the wheel is impaired and a Refocusing becomes necessary.

Der im Patentanspruch angegebenen Erfindung liegt das Problem zugrunde, diese zwei gravierenden Schwachstellen, den Speichenbogen und den lose aufgeschraubten Speichennippel, zu vermeiden.The invention specified in the claim is based on the problem, these two serious weak points, the spoke arch and the loosely screwed-on spoke nipple avoid.

Die mit der Erfindung erzielten Vorteile bestehen darin, daß die Speiche (1) mit fest verbundenem Speichennippel (2), der als Sechskant ausgebildet ist und somit von der Außenseite der Felge (3) her gedreht werden kann, als Ganzes gerade in die im Nabenkörper (4) befindliche Gewindebohrung (5) eingeschraubt wird, wodurch der Speichenbogen entfällt. Durch die Festkonterung am Nabenkörper mittels der auf dem Speichengewinde aufgeschraubten Kontermutter (6) ist die Speiche unter allen Belastungseinflüssen gegen Lösen der Verschraubung geschützt. Somit ist die Gefahr eines Speichenbruches erheblich herabgesetzt, zusätzlich entfällt die Notwendigkeit, das Laufrad nachzuzentrieren.The advantages achieved by the invention are that the spoke ( 1 ) with a fixed spoke nipple ( 2 ), which is designed as a hexagon and can thus be rotated from the outside of the rim ( 3 ), as a whole straight into the hub body ( 4 ) the threaded hole ( 5 ) is screwed in, eliminating the spoke arch. The spoke is protected against loosening of the screw connection under all load influences by the fixed counter on the hub body by means of the lock nut ( 6 ) screwed onto the spoke thread. This significantly reduces the risk of spoke breakage and eliminates the need to re-center the wheel.
