Abstract

L'axe de la roue avant est tenu dans une fourche en structure-coque ou en treillis tubulaire. La fourche comporte quatre rotules disposées suivant deux axes parallèles à l'axe de rotation de la roue. Deux biellettes, constituées chacune par un triangle en tubes soudés relient respectivement les deux rotules supérieures et les deux rotules inférieures à deux rotules fixées sur l'axe de direction, de façon à ce que, vu de profil, l'ensemble détermine un quadrilatère déformable. Une biellette de réaction relie l'une des biellettes de suspension à une platine, articulée autour de l'axe de roue, sur laquelle est fixé l'étrier du frein à disque. L'invention peut s'appliquer à la suspension avant de tout motocycle.
