Abstract
(EN)
This multi-air-chamber tire 1 comprises: partition walls 30 that divide and form a plurality of air chambers 20 adjacent to each other in a tire inner cavity; and ventilation members 10 provided in the partition walls 30, the ventilation members 10 connecting the plurality of air chambers 20 so as to allow ventilation. The ventilation members 10 limit ventilation between the plurality of air chambers 20 on the basis of a prescribed condition indicating that fluid is leaking outside the tire from at least one air chamber among the plurality of air chambers 20.
(FR)
L'invention concerne un pneu à chambres à air multiples (1) comprenant : des parois de séparation (30) qui divisent et forment une pluralité de chambres à air (20) adjacentes les unes aux autres dans une cavité interne de pneu ; et des éléments de ventilation (10) disposés dans les parois de séparation (30), les éléments de ventilation (10) reliant la pluralité de chambres à air (20) de façon à permettre la ventilation. Les éléments de ventilation (10) limitent la ventilation entre la pluralité de chambres à air (20) en s'appuyant sur une condition prescrite indiquant que du fluide s'écoule à l'extérieur du pneu à partir d'au moins une chambre à air parmi la pluralité de chambres à air (20).
(JA)
多気室タイヤ1は、タイヤ内腔に互いに隣接する複数の気室20を区画形成する隔壁30と、隔壁30に設けられ、複数の気室20を通気可能に接続する通気部材10と、を備える。通気部材10は、複数の気室20のうち少なくとも1つの気室から流体がタイヤ外部に漏洩していることを示す、所定の条件に基づいて、複数の気室20間の通気を規制する。
