Abstract
(EN)
A tire assembly with integrated features for adjusting the resonance characteristics of a tire structure includes a pneumatic tire structure, a dielectric elastomer actuator configuration and a charge source. The dielectric elastomer actuator configuration is integrated with selected interior surface locations of the tire structure and may correspond to such embodiments as a plurality of dielectric elastomer portions attached between two rubber plates, a plurality of dielectric elastomer sheets combined to define a volumetric cavity, or a plurality of dielectric elastomer cords attached between interior sidewall locations of a tire structure. Each dielectric elastomer portion includes a layer of elastomeric material provided with first and second electrodes on opposing surfaces thereof and may correspond to a single sheet, a folded sheet, a pleated sheet or a rolled sheet. The charge source is coupled to selected of the first and second electrodes of the dielectric elastomer portions and is configured to selectively apply voltage thereto. The charge source dually functions in some embodiments as an energy storage device for storing electric charge generated when the dielectric elastomer portions are subjected to mechanical forces.

L'invention concerne un ensemble pneu doté de caractéristiques intégrées d'ajustement des caractéristiques de résonance de la structure du pneu comprenant une structure de pneumatique, une configuration d'actionneur élastomère diélectrique ainsi qu'une source de charge. La configuration d'actionneur élastomère diélectrique est intégrée sous la forme de points sélectionnés de surface intérieure de la structure du pneu et elle peut correspondre à des modes de réalisation se présentant sous la forme d'une pluralité de parties élastomères diélectriques fixées entre deux plaques de caoutchouc, une pluralité de nappes élastomères diélectriques combinées pour définir une cavité volumétrique, ou une pluralité de câblés élastomères diélectriques fixés entre les points de la paroi latérale intérieure d'une structure de pneu. Chaque partie élastomère diélectrique comprend une couche de matière élastomère dotée de première et seconde électrodes sur ses surfaces en regard et elle peut correspondre à une seule nappe, une nappe pliée, une nappe plissée ou une nappe laminée. La source de charge est couplée à une des première et seconde électrodes sélectionnée des parties élastomères diélectriques et elle est configurée pour leur appliquer sélectivement une tension. La source de charge présente une dualité de fonctionnement, dans certains modes de réalisation, en tant que dispositif de stockage d'énergie destiné à stocker une charge électrique générée lorsque les parties élastomères diélectriques sont soumises à des forces mécaniques.
