Description
Suspension élastique pour cycles et motocycles. La présente invention a pour but de réa liser une suspension élastique pour cycles et motocycles, permettant l'amortissement des chocs et cahots dus aux inégalités du sol.
Les dessins annexés. donnés à titre dé monstratif, représentent un exemple d'appli cation de l'invention.
Sur un cadre ordinaire a, on remplace la fourche rigide qui relie le pédalier au moyen arrière par une fourche constituée par deux ressorts plats b légèrement incurvés. Le manche de cette fourche est fixé au pédalier et les extrémités des branches, chantournées, sont traversées par l'axe de la roue arrière et portent les tendeurs de chaîne.
Une autre lame de ressort c, munie, près de soi) extrémité supérieure d'un oeillet, est fixée contre le tube porte-selle g, comme l'indique le dessin. Il faut signaler qu'elle peut être placée en avant ou en arrière de ce tube; dans ce dernier cas elle est incurvée.
Une fourrure e munie d'un bras oblique f maintient la lame c contre le tube g et sert de contrefort à la fourche élastique b. Les deux tubes rigides h relient les extré mités des branches de la fourche b à l'oeillet du ressort c. leur liaison avec la lame c pou vant consister en un axe d. qui traverse ledit #illet et dont les extrémités passent à travers des orifiees des deux tubes rigides h. A titre d'indication, ledit axe peut présenter une partie médiàne cylindrique et à ses extrémités deux parties filetées de plus faibles diamètres qui portent des écrous.
Entre l'oeillet et cha cun des écrous vissés à fond viendront s'in tercaler les portées des extrémités des tubes h. Le fonctionnement est le suivant: Sous le poids du cavalier la fourche b fléchit et les tubes rigides h transmettent la poussée au ressort c.
II y a donc bien élasticité verticale du cadre et c'est. cette élasticité. qui amortit les chocs.
Elastic suspension for cycles and motorcycles. The object of the present invention is to provide an elastic suspension for cycles and motorcycles, allowing the damping of shocks and jolts due to uneven ground.
The accompanying drawings. given by way of demonstration, represent an example of application of the invention.
On an ordinary frame a, the rigid fork which connects the crankset to the rear means is replaced by a fork consisting of two flat springs b slightly curved. The handle of this fork is fixed to the crankset and the ends of the branches, scalloped, are crossed by the axis of the rear wheel and carry the chain tensioners.
Another leaf spring c, fitted near the upper end of an eyelet, is fixed against the saddle tube g, as shown in the drawing. It should be noted that it can be placed in front or behind this tube; in the latter case it is curved.
A fur e provided with an oblique arm f maintains the blade c against the tube g and serves as a buttress for the elastic fork b. The two rigid tubes h connect the ends of the branches of the fork b to the eyelet of the spring c. their connection with the blade c can consist of an axis d. which passes through said #illet and whose ends pass through openings of the two rigid tubes h. By way of indication, said pin may have a median cylindrical part and at its ends two threaded parts of smaller diameters which carry nuts.
Between the eyelet and each of the nuts fully screwed in, the spans of the ends of the tubes h. The operation is as follows: Under the weight of the rider, the fork b flexes and the rigid tubes h transmit the thrust to the spring c.
There is therefore indeed vertical elasticity of the frame and it is. this elasticity. which absorbs shocks.
