Title
(DE) STOSSDÄMPFER MIT VARIABLEM DÄMPFUNGSPROFIL
(EN) SHOCK ABSORBER WITH VARIABLE DAMPING PROFILE
(FR) ABSORBEUR DE CHOCS PRÉSENTANT UN PROFIL D'AMORTISSEMENT VARIABLE
Abstract
(EN) Disclosed herein in an energy absorption device that incorporates a diverse range of uses within a single shock absorber. The disclosed energy absorption device is a novel combination of interaction between various components (e.g., piston head, shock tube, cylinder end, external cylinder, and adjustment mechanism) within a single shock absorber. When the components disclosed herein are considered together and designed as an interrelated assembly, the ability to incorporate such a diverse range of uses within a single device emerges. The ability to combine dashpot, square wave, progressive wave, and self-compensating damping in a single device is unprecedented, as is the ability to deliver sublinear damping force vs. input velocity performance in an adjustable device. The disclosed device allows a user to make simpler sizing calculations and decisions, and provides the user with the ability to adjust the shock absorber to a specific application, for example, with the turn of an adjustment knob.
(FR) La présente invention concerne un dispositif d'absorption d'énergie qui intègre une gamme variée d'utilisations à l'intérieur d'un seul absorbeur de chocs. Le dispositif d'absorption d'énergie de l'invention est une nouvelle association d'interaction entre divers éléments (par ex., tête de piston, tube à choc, côté vérin, vérin externe et mécanisme d'ajustement) à l'intérieur d'un seul absorbeur de chocs. Lorsque les éléments décrits dans la description sont envisagés dans leur ensemble et conçus comme un ensemble interdépendant, la capacité à intégrer une telle gamme variée d'utilisations au sein d'un seul dispositif apparaît. La capacité à combiner un amortisseur à fluide, une onde carrée, une onde progressive et un amortissement à auto-compensation dans un seul dispositif est sans précédent, de même que la capacité à exercer une force d'amortissement sous-linéaire par rapport à des performances de vitesse d'entrée dans un dispositif réglable. Le dispositif de l'invention permet qu'un utilisateur réalise des calculs de dimensionnement plus simples et prenne des décisions plus simples, puis permet que l'utilisateur règle l'absorbeur de chocs en fonction d'une application spécifique, par exemple, en tournant un bouton de réglage.
