Title (EN) BI-DIRECTIONAL NON-LINEAR SPRING
(FR) RESSORT NON LINÉAIRE BIDIRECTIONNEL
Abstract:
(EN) A linear spring member (150) having an annular region (151) with a first thickness connected in series by cylindrical regions (152, 153) having a second thickness, wherein the first thickness is less than the second thickness. Outer portions of adjacent annular regions (151) are coupled together by a first cylindrical region (152) and inner portions of adjacent annular regions (151) are coupled together by a second cylindrical region (153) such that the effective spring rate of the bi-directional spring device (150) increases symmetrically as it is displaced in either compression or tension.
(FR) L'invention concerne un élément ressort linéaire (150) comportant une région annulaire (151) présentant une première épaisseur et reliée en série par des régions cylindriques (152, 153) présentant une seconde épaisseur, la première épaisseur étant inférieure à la seconde épaisseur. Les parties externes des régions annulaires adjacentes (151) sont accouplées l'une à l'autre par une première région cylindrique (152) et les parties internes des régions annulaires adjacentes (151) sont accouplées l'une à l'autre par une seconde région cylindrique (153), de sorte que la constante de rappel effective de l'élément ressort bidirectionnel (150) augmente de manière symétrique lorsqu'il est déplacé soit en compression, soit en tension.
