Abstract:
La suspension d'une roue d'une motocyclette comporte un élément élastique (1) ayant une forme en C dans le plan de flexion et articulé par ses extrémités au levier pendulaire (5) portant la roue et au cadre (3) de la motocyclette. L'élément élastique (1) de la suspension permet d'améliorer la souplesse de marche de la motocyclette grâce à la flexibilité élevée des tronçons d'extrémité de l'élément élastique (1) fonctionnant comme un ressort à lames dans le sens de leur petite résistance, tandis que le tron-Son médian de l'élément élastique fonctionne dans le sens de sa plus grande résistance.
Abstract:
A suspension mechanism for a bicycle includes a pair of generally oppositely directed support arms (3, 4). The front support arm (3) is connected to support the front fork (7) for the front wheel (8) of the bicycle, and the rear support arm (4) forms the fork for the rear wheel (9). The support arms are pivotably mounted, by means of a hub (20), about parallel axes with respect to a load bearing member (16) comprising a seat stalk to which a bicycle saddle is mounted. The support arms are urged away from the load bearing member by biasing means in the form of a leaf spring set. (17).
Abstract:
A bicycle frame assembly includes at least one frame member having a connecting portion, and at least one shock absorber formed as a looped plate member disposed detachably in the connecting portion. The looped plate member has two resilient plate portions each having two opposite ends, and an intermediate portion between the opposite ends. The resilient plate portions are interconnected at the opposite ends. The intermediate portions of the resilient plate portions extend away from each other.
