Abstract

Abstract Translated from French L'invention concerne les trains avant de véhicules à deux roues permettant de dissocier les fonctions de suspension et de direction grâce à un assemblage mécanique s'intégrant dans la roue avant. Le procédé selon l'invention permet de réaliser un train avant possédant un très bon guidage, très peu encombrant, très léger, présentant peu de variations d'empattement, possédant un centre de gravité très bas, de multiples possibilités de réglage facile à maîtriser. Il comprend un triangle inférieur 2 et 2' traversent le moyeu de la roue et démontable pour la dépose de celle-ci, un bras latéral 4 et 5 faisant office de pivot, un triangle supérieur 3 positionné au-dessus de la roue, qui actionne l'amortisseur 13, un guidon 15 qui contrôle la biellette 16 et le pivot 4 et 5. L'invention concerne principalement les motocyclettes de haute performance. The invention relates to the front axles of two-wheeled vehicles making it possible to dissociate the suspension and steering functions by means of a mechanical assembly integrating into the front wheel.
