Abstract
Description
DESCRIPTION La présente invention concerne un système de suspension pour vélos tous-terrains, ou plus précisément l'emplacement du pédalier sur ce système afin d'en exploiter au mieux les qualités. DESCRIPTION The present invention relates to a suspension system for off-road bikes, or more precisely the location of the pedal on this system in order to exploit the best qualities.
Afin de comprendre l'importance de cet emplacement, il convient de préciser qu'un pédalier situé sur la partie suspendue (le cadre du vélo) améliorera l'effet de suspension<B>;</B> c'est ce que l'on retrouve sur les systèmes de cantilevers, parallélogrammes déformables et systèmes mac pherson <B> .</B> To understand the importance of this location, it should be noted that a pedal on the suspended part (the frame of the bike) will improve the effect of suspension <B>; </ B> that's what the found on cantilever systems, deformable parallelograms and mac pherson systems. </ B>
Les problèmes engendrés par ces systemes sont la perte de rigidité au niveau du cadre et la variation de longueur de chaîne entre le pédalier et l'axe de roue arrière. The problems caused by these systems are the loss of stiffness at the frame and the variation in chain length between the crankset and the rear wheel axle.
<B>A</B> l'inverse, un pédalier situé sur la partie oscillante (triangle arrière unifié) favorisera la motricité au détriment de l'effet suspensif On voit sur la figure<B>1</B> que le pédalier suit les mouvements de la roue dans une certaine mesure, ce qui réduit le débattement réel entre le niveau d'axe de roue et celui du pédalier. <B> A </ B> the reverse, a pedal on the oscillating part (unified rear triangle) will promote the motor at the expense of the suspensive effect We see on the figure <B> 1 </ B> that the pedalboard follows the movements of the wheel to a certain extent, which reduces the actual clearance between the wheel axle level and that of the pedal.
Le problème posé est de concevoir un système alliant<B>à</B> la fois motricité et effet suspensif Le système selon l'invention remédie<B>à</B> ce problème<B>;</B> le pédalier se trouve situé sur le bras oscillant formant ainsi une structure rigide assurant une motricité maximale. Cette structure est fixée au cadre par l'intermédiaire d'un parallélogramme déformable particulier et permet au pédalier de descendre lorsque l'axe de roue monte, assurant ainsi un effet suspensif supérieur aux systèmes précédemment cités. The problem is to design a system combining <B> with </ B> both motricity and suspensory effect The system according to the invention remedies <B> to </ B> this problem <B>; </ B> the pedalboard is located on the swingarm thus forming a rigid structure ensuring maximum traction. This structure is fixed to the frame by means of a particular deformable parallelogram and allows the pedal to descend when the wheel axle rises, thus providing a superior suspensive effect to the aforementioned systems.
La particularité de ce parallélogramme (modèle<B>déjà</B> existant et breveté) réside dans l'emplacement des biellettes. Celles-ci sont très rapprochées l'une de l'autre<B>à</B> leurs points de pivots sur le cadre et encore plus rapprochées<B>à</B> leurs points de pivots sur le bras oscillant. Leurs directions étants différentes, elles créaient pendant leurs rotations un basculement de la partie oscillante<B>;</B> le pédalier descend lorsque l'axe de roue monte. La différence de niveau entre le pédalier et l'axe de roue donne le débattement réel. The particularity of this parallelogram (model <B> already </ B> existing and patented) lies in the location of the rods. These are very close to each other <B> at </ B> their pivot points on the frame and even closer to <B> at </ B> their pivot points on the swingarm. Their directions being different, they created during their rotations a tilting of the oscillating part <B>; </ B> the pedal descends as the wheel axle rises. The difference in level between the crankset and the wheel axle gives the actual travel.
L'amortisseur est monté entre le cadre et le triangle arrière, bénéficiant d'une compression<B>à</B> progressivité variable par la particularité du déplacement du point de fixation de l'amortisseur sur le bras oscillant, phénomène créait par le parallélogramme déformable. Le pédalier et l'axe de roue étant sur la même partie du cadre,<B>il</B> n'y a pas de variation de longueur de chaîne et d'angle de chaîne par rapport au pédalier<B>;</B> les sauts de chaîne peuvent ainsi être supprimés par un système anti-déraillement rendu plus efficace par la suppression des mouvements de chaîne et par la possibilité d'appliquer une tension de chaîne plus importante puisqu'elle ne varie pas pendant l'oscillation. Les dessins annexés illustrent l'invention<B>:</B> <B>-</B> La figure<B>1</B> représente le système de triangle arrière unifié. <B>-</B> La figure 2 représente le système selon l'invention. The damper is mounted between the frame and the rear triangle, benefiting from compression <B> to </ B> progressive variable by the particularity of the displacement of the point of attachment of the damper on the swingarm, a phenomenon created by the deformable parallelogram. The pedal and the wheel axle being on the same part of the frame, <B> it </ B> there is no variation of length of chain and angle of chain with respect to the pedal <B>; < Chain breaks can thus be eliminated by an anti-derailment system made more efficient by suppressing chain movements and by the possibility of applying a greater chain tension since it does not vary during oscillation. . The accompanying drawings illustrate the invention. <B>: </ B> <B> - </ B> Figure <B> 1 </ B> represents the unified rear triangle system. <B> - </ B> Figure 2 shows the system according to the invention.
En référence<B>à</B> ces dessins, le système comporte un boîtier de pédalier<B>(1)</B> fixé sur le bras oscillant (2) au niveau du pivot inférieur<B>(3)</B> de la biellene inférieure (4), plus exactement entre 2 et 4 cm en dessous du pivot inférieur<B>(3)</B> et le plus proche possible que la construction puisse l'autoriser. L'amortisseur<B>(5)</B> est monté entre le cadre<B>(6)</B> et le bras oscillant (2) par l'intermédiaire du pivot<B>(7).</B> With reference to these drawings, the system includes a bottom bracket <B> (1) </ B> attached to the swingarm (2) at the bottom pivot <B> (3) < / B> of the lower biellene (4), more exactly between 2 and 4 cm below the lower pivot <B> (3) </ B> and as close as possible that the construction can authorize it. The damper <B> (5) </ B> is mounted between the frame <B> (6) </ B> and the swingarm (2) via the pivot <B> (7). </ B>
