Description

BeschreibunDescription

Die vorliegende Erfindung bezieht sich auf einen Tachometer, insbesondere für Fahrräder und Mopeds, bei dem die Messung mittels eines an einem ortsfesten Teil des Fahrzeugs befestigten Reed-Relais und einer Anzahl an einem Rad befestigter Permanentmagnete erfolgt, wobei letztere derart angeordnet sind, daß sie sich beim Drehen des Rades an dem Reed-Relais vorbeibewegen.The present invention relates to a speedometer, especially for bicycles and mopeds, in which the measurement by means of a fixed part of the Vehicle-mounted reed relays and a number of permanent magnets attached to a wheel takes place, wherein the latter are arranged such that they move past the reed relay when the wheel is turned.

In der US-PS 3 898 563 ist ein Tachometer dieser Art beschrieben. Bei diesem bekannten Tachometer sind die Permanentmagnete an den Speichen des Rades befestigt. Diese Magnetanordnung hat gewisse Nachteile. Einer dieser Nachteile besteht darin, daß sich die Montage der Magnete als schwierig erweisen kann, ein weiterer Nachteil ist ferin zu sehen, daß es schwierig ist, die Magnetein exakten gegenseitigen Abständen oder Intervallen anzuordnen. Als weiterer Nachteil ist anzusehen, daß die Anzahl der Magnete bis zu einem gewissen Grad durch die Anzahl der Speichen festgelegt wird.In U.S. Patent 3,898,563 there is a speedometer of this type described. In this known speedometer, the permanent magnets are attached to the spokes of the wheel. This magnet arrangement has certain disadvantages. One of these Disadvantages are that the assembly of the magnets can be difficult, another disadvantage is Furthermore, it can be seen that it is difficult to arrange the magnets at exact mutual distances or intervals. as Another disadvantage is that the number of magnets depends to a certain extent on the number of spokes is determined.

Der Erfindung liegt die Aufgabe zugrunde, einen Tachometer der eingangs genannten Art anzugeben, der die genannten Nachteile nicht aufweist.The invention is based on the object of specifying a speedometer of the type mentioned at the beginning which has the disadvantages mentioned does not have.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Permanentmagnete mit gleichmäßigen Abständen in einen ringförmigen Halter eingeformt sind, und daß der Halter mit einerThis object is achieved in that the Permanent magnets are molded at regular intervals in an annular holder, and that the holder with a

Wie man Fig. 5 entnimmt, ist die ringförmige Scheibe 3 mittels eines zugehörigen Befestigungsteils 14 sicher um die Speichen 2 des Rades befestigt. Der Befestigungsteil 14 besteht aus zwei mit der ringförmigen Scheibe 3 zusammengeschraubten Hälften. Der Aufnehmer 6 ist an der Yordergabel 5 mittels einer herkömmlichen Befestigungsschelle 16 befestigt. Der Aufnehmer 6 kann allerdings auch auf einer Platte montiert sein, die an dem Habenbolzen des Rades befestigt ist.As can be seen from FIG. 5, the annular disk is 3 securely fastened around the spokes 2 of the wheel by means of an associated fastening part 14. The fastening part 14 consists of two halves screwed together with the annular disk 3. The transducer 6 is at the Yorder fork 5 fastened by means of a conventional fastening clamp 16. The transducer 6 can, however, also be mounted on a plate attached to the wheel's jack bolt.

Die Erfindung ist nicht auf das Ausführungsbeispiel, bei dem sieben Permanentmagnete vorgesehen sind,-beschränkt. Diese Anzahl von Magneten eignet sich für ein 26-Zoll-Rad. Bei Rädern mit größerem oder kleinerem Durchmesser kann eine größere oder kleinere Anzahl von Magneten verwendet werden. Die Anzahl von Permanentmagneten in dem hier dargestellten bevorzugten Ausführungsbeispiel der Erfindung wurde gewählt, um die Registrierung von einem Kilometer pro Stunde entsprechend etwa einem Impuls pro Sekunde zu erzielen. Der Fachmann erkennt, daß die Meßimpulse des Tachometers auch herangezogen werden können zum Erzeugen von Impulsen für einen Kilometerzähler, der in dem Instrumentengehäuse 8 untergebracht ist.The invention is not limited to the exemplary embodiment the seven permanent magnets are provided, -limited. This number of magnets is suitable for a 26 inch wheel. A larger or smaller number of magnets can be used for wheels with a larger or smaller diameter will. The number of permanent magnets in the preferred embodiment of FIG Invention was chosen to record one kilometer per hour corresponding to approximately one pulse per hour Second to achieve. The person skilled in the art recognizes that the measuring pulses the speedometer can also be used to generate pulses for an odometer, the is housed in the instrument housing 8.
