Abrégé
(EN)
Apparatus and methods are disclosed for passive stabilization of a wheeled object (10) by employing secondary wheels (16a 16b) rotating about secondary axes offset from a common axis of a primary set of wheels (14a, 14B), where the secondary wheels are positioned such that tilting of the object during rolling causes one of the secondary wheels to contact the surface and counteract tilting tendencies. The offset of the secondary axes can include angular, vertical, and/or horizontal components.
(FR)
L'invention concerne des appareils et des procédés de stabilisation passive pour un objet (10) à roues doté de roues secondaires (16 a, 16 b) tournant autour d'axes secondaires décalés par rapport un axe commun du jeu primaire de roues (14 a, 14 B). Les roues secondaires sont disposées de telle sorte que le basculement de l'objet pendant qu'il roule provoque la mise en contact d'une des roues secondaires avec la surface et contrecarre ainsi les tendances au basculement. Le décalage des axes secondaires peut comprendre des éléments angulaires, verticaux et/ou horizontaux.
