Title
(EN) SYSTEMS AND METHODS FOR PROVIDING WHEELS HAVING VARIABLE SPRING RATES
(FR) SYSTÈMES ET PROCÉDÉS POUR FOURNIR DES ROUES AYANT DES CONSTANTES DE RAPPEL VARIABLES
Abstract
(EN)
A wheel (10) is disclosed that includes an inner hub (12), an outer rim (14), and a plurality of resilient elements (16) that exhibit a first spring constant that is the same for all elements, and a second spring constant that is higher than the first spring constant for elements being compressed beyond a threshold deflection.
(FR)
Cette invention concerne une roue (10) qui comprend un moyeu interne (12), une jante externe (14), et une pluralité d'éléments élastiques (16) qui présentent une première constante de rappel qui est identique pour tous les éléments, et une seconde constante de rappel qui est supérieure à la première constante de rappel pour des éléments qui sont comprimés au-delà d'une déviation seuil.
