Abstract
Description
AMORTISSEUR de VIBRATIONS et CHOCS
à LAMINAGE VARIABLE
Cette invention concerne les éléments techniques destinés à amortir les vibrations et les chocs entre deux parties mobiles l'une par rapport à l'autre. VIBRATION AND SHOCK ABSORBER
VARIABLE LAMINATION
This invention relates to technical elements intended to dampen vibrations and shocks between two moving parts relative to each other.
Jusqu'à présent, tous les systèmes destinés à cette fonction étaient à laminage dthuile réglable ou non, mais fixe lors du travail. La résistance est donc la meme aux petits chocs ou vibrations (course d'amortissement petite) ou aux grands (course d'amortissement longue). Ce qui conduit à un amortissement trop dur, insensible aux petits chocs, ou trop souples et inefficace pour les grands chocs. Until now, all systems intended for this function have been with or without adjustable oil rolling, but fixed during work. The resistance is therefore the same to small shocks or vibrations (small damping stroke) or to large ones (long damping stroke). This leads to too hard damping, insensitive to small shocks, or too flexible and ineffective for large shocks.
L'invention est composée d'une partie inférieure cylindrique contenant en son centre une forme de revolution autour diun axe vertical, et à profil en "courbe", et d'une partie supérieure composée de deux cylindres coaxiaux, celui de diamêtre supérieur coulissant dans la partie inférieure, l'autre portant à son extrémité un ensemble de pièces incluant des leviers, leurs axes et leur support. Ces leviers prennent appui d'une part sur un anneau coulissant sur le cylindre qui les porte, d'autre part sur la partie inférieure centrale, imprimant à cet anneau ainsi qu'aux pointeaux qu'il porte un mouvement vertical permettant l'obstruction des alésages de passage d'huile, lors de l'enfoncement de la partie supérieure dans la partie inférieure.Le pivotement des leviers provient de l'augmentation de diamêtre de la partie centrale inférieure, dont la forme sera choisie en conséquence. Les alésages de passage d'huile sont percés dans un disque reliant les deux cylindres supérieurs. The invention is composed of a cylindrical lower part containing in its center a form of revolution around a vertical axis, and with a "curved" profile, and of an upper part composed of two coaxial cylinders, that of upper diameter sliding in the lower part, the other carrying at its end a set of parts including levers, their axes and their support. These levers are supported on the one hand on a ring sliding on the cylinder which carries them, on the other hand on the central lower part, imparting to this ring as well as to the needles which it carries a vertical movement allowing the obstruction of the oil passage bores, when the upper part is pushed into the lower part. The pivoting of the levers results from the increase in diameter of the lower central part, the shape of which will be chosen accordingly. The oil passage bores are drilled in a disc connecting the two upper cylinders.
Le retour d'huile est prévu par un système à clapet classique.The oil return is provided by a conventional valve system.
Le retour de l'anneau support des pointeaux est assuré par ressort.The return of the needle support ring is ensured by spring.
Le dessin annexe est un schéma cinématiquement minimal montrant le principe de fonctionnement de l'invention. The accompanying drawing is a kinematically minimal diagram showing the operating principle of the invention.
Le dispositif comprend la partie 1, constituée des deux cylindres supérieurs positionnés par leur fond commun d'une part, et le disque 2 percé des alésages 11 et 12 d'autre part, la partie 3 portant les leviers 4 et fixe par rapport à 1, l'anneau 5 portant les pointeaux 6, le clapet de retour d'huile 7 et son arrêt en translation 8, la partie inférieure centrale 9 contenue dans le cylindre inférieur 10.
Lors de l'enfoncement de la partie supérieure I dans la partie inférieure 2, l'huile a tendance à s'échapper des volumes A vers les volumes B sous l'effet de la pression et par les alésages 11 du disque ûniquement, les autres étant obturés par le clapet 7, ces alésages là (11) étant réduits jusqu'à l'obturation du fait même de l'enfoncement correspondant de l'amortisseur, celui-ci s oppose de plus en plus au mouvement.C'est l'effet du laminage d'huile variable.The device comprises part 1, consisting of two upper cylinders positioned by their common bottom on the one hand, and the disc 2 pierced with bores 11 and 12 on the other hand, part 3 carrying the levers 4 and fixed relative to 1 , the ring 5 carrying the needles 6, the oil return valve 7 and its stop in translation 8, the central lower part 9 contained in the lower cylinder 10.
When the upper part I is pushed into the lower part 2, the oil tends to escape from the volumes A towards the volumes B under the effect of the pressure and through the bores 11 of the disc only, the others being closed by the valve 7, these bores there (11) being reduced until obturation by the very fact of the corresponding depression of the damper, the latter is increasingly opposed to the movement. effect of variable oil rolling.
Ce dispositif permet non seulement un amortissement variable dans sa course, mais aussi, par changement de la forme de la partie 9, on peut modifier à volonté ses caractéristiques d'amortissement. This device allows not only a variable damping in its course, but also, by changing the shape of the part 9, one can modify at will its damping characteristics.
Des applications de ce système peuvent intéresser notamment les secteurs du transport, de l'automobile et du motocyclisme. Applications of this system may be of interest in particular to the transport, automobile and motorcycling sectors.
Remarque : a) le nombre de leviers 4 ainsi que de pointeaux 6 et d'alésages 11
et 12 n'est pas fixé.Note: a) the number of levers 4 as well as of needles 6 and bores 11
and 12 is not fixed.
b) le cylindre inférieur 10 est bien sûr muni d'un fond sur lequel
est maintenue la pièce 9.b) the lower cylinder 10 is of course provided with a bottom on which
part 9 is maintained.
c) I1 faudra prévoir, pour le fonctionnement correct de l'invention,
un jeu radial suffisant des pointeaux 6 et de la pièce 9 par rapport à leurs bases respectives.c) It will be necessary to provide, for the correct functioning of the invention,
sufficient radial clearance of the needles 6 and of the part 9 with respect to their respective bases.
d) Le retour de l'anneau 5 est assuré par ressort. d) The return of the ring 5 is ensured by spring.
e) Lìinvention sera emplie d'huile de façon que tout le volume inté
rieur du cylindre de petit diamêtre de la pièce 1 en soit empli. e) The invention will be filled with oil so that the entire interior volume
of the small diameter cylinder of part 1 is filled with it.
