To solve problems where the existing springs do not offer a good solution, at least without using associated mechanisms that increase cost and reduce reliability, a new kind of spring is hereby proposed, hereafter designates as hY-spring. The Y-spring is a leaf spring whose geometry allows for a self-limited deformation, has a chosen initial stiffness and, when the spring is compressed, tends asymptotically to infinity, while the bending moment and the maximum stress at any given section do not overtake a value defined initially as acceptable. An alternate mounting of the same spring allows it to support traction forces and act as a true constant reaction spring. The Y-spring is made of two leafs, usually both curved, rigidly joined together at one of their ends in such a way that the surfaces of both touch each other at that end. The curvature of each of the leafs has the same sign along their entire working length. The curvature and the bending modulus along each leaf are such that the only points to touch each other are the ones in the immediate vicinity of those already touching. |
