Abstract:
L'objet de l'invention est un dispositif de limitation de vibrations dans un vélo comprenant un cadre (10) et au moins deux roues (12), ledit dispositif comprenant au moins un dispositif (20) de filtration et d'absorption d'une gamme donnée de vibrations comprenant des moyens de dissipation (24) de l'énergie vibratoire issue de ladite gamme donnée de vibrations et des moyens de solidarisation (26) à au moins une partie du cadre (10) dudit vélo, caractérisé en ce que les moyens de dissipation (24) comprennent au moins une extrémité fixe (27) reliée aux moyens de solidarisation (26) et au moins une extrémité libre (29).
Abstract:
A suspension for a motocycle wheel comprises an elastic element (1) C-shaped in the bending plane and hingedly connected by its end to the pendulum lever (5) carrying the wheel and to the frame of the motocycle. The elastic element (1) in the suspension makes it possible to improve the performance characteristics of the motocycle due to the increased elasticity of the extreme parts of the elastic element (1) which operate as a leaf spring in the directions of least resistance, whereas in its middle part the elastic element (1) operates in the direction of greatest resistance.
Abstract:
The invention relates to a bicycle frame comprising a base frame and at least one device (14, 60), which is mounted on this base frame, provided in the form of a brace structure, and has an accommodating area for accommodating a wheel. The invention also relates to a bicycle fork and to a method for producing a bicycle frame.
Abstract:
A suspension device for a rear wheel of a cycle, especially a motorcycle, comprising a leaf spring. This leaf spring is disposed in a rear arm of said cycle.
Abstract:
Several embodiments of rear wheel suspension systems for motorcycles wherein the leaf spring is employed that is contained within the suspension arm so as to be protected and yet facilitate servicing. The spring is loaded so as to provide a progressive rate and various damper arrangements are also disclosed employing either rotary or tubular-type dampers.
Abstract:
A motorcycle rear wheel frame is pivotally mounted to the motorcycle main frame. A shaft is positioned on a pivot axis of the rear wheel frame and the main frame of the motorcycle. Rigidly attached to the shaft is one end of a leaf spring. The other end of the leaf spring contacts a transverse cross member of the swing arm so that pivotal movement of said rear frame with respect to the main frame is primarily absorbed by the leaf spring.
Abstract:
A rear wheel supporting system for a motorcycle wherein an end portion of a rear axle--which is supported by the rear end portions of a rear fork--on the side opposite to the side where a rear wheel driving means is disposed, is supported so as to be movable resiliently in the longitudinal direction of the vehicle body.
