Abstract
(DE)
Eine Federgabel weist eine zentrale, im Steuerkopf (5) eines Zweiradrahmens untergebrachte Federeinrichtung auf, wobei ein längsverzahntes oder als Polygon ausgeführtes Gabelschaftrohr (1) in einer entsprechend geformten Lagerbuchse (2) verdrehsicher geführt ist, welche Lagerbuchse (2) ihrerseits verdrehsicher in einem im Steuerkopf (5) drehbar gelagerten Führungsrohr (3) gelagert ist, und wobei die Lagerbuchse (2) ferner elastisch ausgeführt und radial verkleinerbar ist, wodurch das Spiel nachstellbar ist.
(EN)
A spring fork has a central spring device which is arranged in the control head (5) of a two-wheel frame. A longitudinally toothed handlebar stem or a handlebar stem which is configured in the form of a polygon (1) is guided in a correspondingly shaped bearing bushing (2) in such a way that it is resistant to twisting, said bearing bush (2) itself being twist-resistantly mounted in a guide tube (3) which is rotationally mounted in the control head (5). The bearing bush (2) is also configured in such a way that it is elastic and radially reducible so that the play can be adjusted.
(FR)
Une fourche élastique présente un dispositif d'amortissement central logé dans la tête de commande (5) d'un cadre de bicyclette. Un tube de fourche (1) à denture longitudinale ou conçu comme un polygone est guidé bloqué en rotation dans une douille (2) de forme correspondante. Cette douille (2) est, à son tour, montée bloquée en rotation dans un tube de guidage (3) monté pivotant dans la tête de commande (5). La douille (2) est également élastique et peut être radialement réduite, ce qui permet le réglage ultérieur du jeu.
