Abstract
Fräsvorrichtung
zum Planfräsen
des Postmountsockels ist dadurch gekennzeichnet, dass der Fräskopf genau
im rechten Winkel zur Postmount Aufnahme herangeführt werden
kann:
Über
die Achse (2), die in die Ausfallenden der Gabel gespannt wird,
kann Bauteil 1 (1) in der horizontalen Ebene und Kreisbahn um die
Achse (2) verschoben werden.
Über Bauteil 1 (1) wird mittels
der Rundfeder (5) Bauteil 2 (3) verbunden, welches sich nun in drei
Ebenen an den Postmount Sockel anfahren lässt. Dadurch ist gewährleistet,
dass der Fräskopf
genau im rechten Winkel zur Postmount Aufnahme steht.Milling device for face milling of the Postmountockels is characterized in that the milling head can be brought exactly at right angles to the Postmount recording:
About the axis (2), which is stretched in the dropouts of the fork, component 1 (1) in the horizontal plane and circular path about the axis (2) can be moved.
Component 2 (3) is connected via component 1 (1) by means of the round spring (5), which can now be moved to the Postmount base in three levels. This ensures that the milling head is exactly at right angles to the postmount holder.
Description
Bisher sind auf dem Markt für Fahrradfedergabeln zwei Standards zur Aufnahme des Scheibenbremssattels bekannt:
- 1.) IS 2000 (= Internationaler Standard 2000)
- 2.) PM® (= Postmount Standard)
- 1.) IS 2000 (= International Standard 2000)
- 2.) PM ® (= Postmount Standard)
Beim erstgenannten Standard wird der Bremssattel von der Seite an die Aufnahme der Gabel geschraubt, dadurch wird die Schraube auf Scherung belastet.At the The first standard is the caliper from the side to the Take the fork screwed, this causes the screw to shear loaded.
Beim Postmount Standard wird der Bremssattel in Fahrtrichtung geschraubt, somit wird die Schraube im Kraftfluss der einwirkenden Bremskräfte belastet. Der PM® Standard setzt sich auf dem Markt zunehmend durch.With the Postmount standard, the caliper is screwed in the direction of travel, so the screw is loaded in the force flow of the applied braking forces. The PM ® standard is increasingly gaining ground in the market.
Problematisch sind bei beiden Standards die Fertigungstoleranzen und eventuelle Unebenheiten an den Aufnahmen für den Bremssattel. Um jedoch einen 100%ig sauberen Sitz des Bremssattels zur Bremsscheibe zu gewährleisten, d. h. der Bremssattel sollte im rechten Winkel zur Bremsscheibe stehen, muss die Aufnahme plan gefräst werden.Problematic For both standards, the manufacturing tolerances and possible ones are Bumps on the recordings for the caliper. However, a 100% clean seat of the caliper to ensure the brake disc d. H. The caliper should be at right angles to the brake disc stand, the recording must be milled plan.
Für den PM® Standard existiert bis dato noch keine Vorrichtung und so liegt der im Schutzanspruch 1 angegeben Erfindung das Problem zugrunde, eine Fräsvorrichtung entwickelt und konstruiert zu haben, die es ermöglicht den Postmount Standard an Fahrradfedergabeln plan zu fräsen.For the PM ® standard exists so far no device and so is the invention specified in the protection claim 1 the problem of having developed and constructed a milling device, which makes it possible to mill the Postmount standard bicycle spring forks.
Dieses Problem wird mit den in Schutzanspruch 1 aufgeführten Merkmalen gelöst.This Problem is solved with the features listed in protection claim 1.
Um den Fräskopf – der in Bauteil 2 geführt wird – genau parallel und im gleichen Abstand an die Sockel heranzuführen, besitzt die Fräsvorrichtung eine Referenzplatte die in Schutzanspruch 2 beschrieben wird.Around the milling head - the in Component 2 is guided - exactly has parallel and at the same distance to the pedestals, has the milling device a Reference plate which is described in protection claim 2.
Weitere vorteilhafte Gestaltungsmerkmale der Erfindung sind die Bronze- und/oder Messingbuchsen, die einen selbst schmierenden Lauf des Fräsers gewährleisten. Ebenso die Rundfeder in der dazugehörigen Nutführung von Bauteil 2, die eine problemlose Einstellung bietet. Diese Merkmale sind in Schutzanspruch 3 und 4 dargestellt.Further advantageous design features of the invention are the bronze and / or brass bushings which ensure a self-lubricating run of the milling cutter. Likewise, the round spring in the associated groove guide of component 2, the problem-free Setting offers. These features are in protection claim 3 and 4 shown.
