Abstract

A measuring unit is firmly installed at the rear construction of a vehicle frame. A flexible measuring unit is inserted into the fork of the two-wheeled device. The rear measuring unit has an optical device installed to emit light as a measurement indicator about the reference plane area of the running wheel.

Description

Das Fahrrad gewinnt zunehmend als Verkehrsmittel an Bedeutung, sei es als Alltagsrad, als alternative zum Auto oder als Sportgerät (Rennrad oder Mountainbike).The bicycle is becoming increasingly important as a means of transport, be it as an everyday bike, as an alternative to a car or as sports equipment (racing bike or Mountain bike).

Mit der fortschreitenden technischen Entwicklung der einzelnen Bauteile wie z. B. der Bremsen und der Fahrwerke erhöhen sich die gefahrenen Geschwindigkeiten insbesondere bei den Sportgeräten. Damit ein­ hergehend steigen die Ansprüche an das Fahrwerk. Z. B. Geradeauslauf und Spurtreue.With the progressive technical development of the individual components such as B. the brakes and the chassis increase the driven Speeds especially in sports equipment. So that one As a result, the demands on the chassis increase. E.g. straight-ahead and directional stability.

Bisher steht dem Fahrradmechaniker kein probates Hilfsmittel zur Verfügung dieses zu überprüfen, insbesondere nach einem Sturz oder einem Unfall.So far, the bicycle mechanic has no proven aid Available to check this, especially after a fall or an accident.

Die herkömmlichen Methoden, wie die Sichtprüfung der Spur, Rahmenlineal oder Meßlatte sind wenig Aussagekräftig oder zu ungenau.The traditional methods, such as visual inspection of the track, frame ruler or measuring stick are not very meaningful or too imprecise.

Die Überprüfung auf dem Messtisch ist sehr Aufwendig, da Rahmen und Gabel vollständig demontiert werden müssen. Die Rohrebene wird als Basis angesetzt, nicht aber die Laufradebene (Spur) direkt überprüft.The check on the measuring table is very complex because of the frame and Fork must be completely dismantled. The pipe level becomes the base attached, but not the impeller level (track) checked directly.

Der Erfindung liegt die Aufgabe zu Grunde eine Vorrichtung zu schaffen, die eine schnelle und wenig Aufwendige Analyse der wesentlichen Fahrwerksparameter eines Fahrrades zulässt.The invention is based on the object of providing a device which is a quick and inexpensive analysis of the essentials Suspension parameters of a bicycle.

Beim vorliegenden Verfahren werden die Ebenen der beiden Laufräder miteinander verglichen und ein Parallelversatz und/oder ein Winkel­ versatz festgestellt. Für die Fahrdynamik des Rahmens ist dies im wesentlichen verantwortlich.In the present method, the levels of the two impellers compared with each other and a parallel offset and / or an angle misalignment determined. For the driving dynamics of the frame, this is in essentially responsible.

Die Mittigkeit des Sattels und des Tretlagers ist mit diesem Verfahren ebenfalls zu kontrollieren.The center of the saddle and the bottom bracket is with this procedure also control.

Die Messeinheit besteht aus einer Achse, die an Stelle des Laufrades ein­ gesetzt wird. Um die Achse rotiert ein Lichtstrahl, der die Ebene des Lauf­ rades darstellt. Durch die ortsfeste Installation der hinteren Messeinheit (Zeichnung 1,a) wird diese Ebene als Referenzebene festgelegt. Mit Hilfe des rotierenden Lichtstrahls kann diese Ebene an der Raumbegrenzung dargestellt werden.The measuring unit consists of an axis that replaces the impeller is set. A beam of light rotates around the axis, reflecting the plane of the barrel represents rades. Due to the fixed installation of the rear measuring unit (Drawing 1, a) this level is defined as the reference level. With help of the rotating light beam, this level can be at the space boundary being represented.

Der zu vermessende Rahmen wird mit den hinteren Ausfallenden in der Messeinheit eingespannt.The frame to be measured is with the rear dropouts in the Measuring unit clamped.

Eine zweite Messeinheit (Zeichnung 1,b) wird in die Gabel eingesetzt. Mit dem Lichtstrahl wird die Gabel geradeaus horizontal ausgerichtet. In dieser Position kann mit dem Lichtstrahl die Ebene des Vorderrades mit der Ebene des Hinterrades verglichen werden.A second measuring unit (drawing 1, b) is inserted into the fork. With the fork is aligned horizontally straight ahead. In this Position can with the light beam the plane of the front wheel with the plane of the rear wheel are compared.

Wiederholt man die Messung mit der um 180° gedrehten Gabel, so lassen sich Rückschlüsse auf eventuelle Abweichungen vom Ideal ziehen: Ist bei beiden Messungen die Abweichung gleichsinnig, so ist der Hauptrahmen aus der Ebene. Ist die Abweichung gegensinnig, so ist die Gabel verzogen (Winkelversatz).If you repeat the measurement with the fork rotated by 180 °, leave so draw conclusions about possible deviations from the ideal: If the deviation is the same in both measurements, the is Main frame from the plane. If the deviation is opposite, it is Fork distorted (angular misalignment).
