阅读说明：本技术 用于重型土木工程车辆的轮胎的导电性胎冠结构 (Electrically conductive crown structure for a tyre of a heavy civil engineering vehicle ) 是由 T·鲁瓦耶 于 2018-03-26 设计创作，主要内容包括：本发明涉及子午线轮胎(10),更具体地涉及子午线轮胎(10)的胎侧(20)以及其胎面(30),用以使轮胎的温度最小化并同时确保其电导率。胎面(30)包括两个翼部(311、312)和中间部分(32)。这些部件倚靠在沿径向位于胎面(30)内侧的基层(33)上。基层(33)包括部分地与胎面翼部(311、312)接触的侧面部分(331、332)。根据本发明,与胎体增强件接触的这种轮胎胎冠结构有助于在轮胎安装到轮辋上并贴在地面上时构成电荷在轮辋与地面之间的优等传导通路。(The present invention relates to a radial tire (10), more particularly to a sidewall (20) of a radial tire (10) and a tread (30) thereof, for minimizing the temperature of the tire while ensuring the electrical conductivity thereof. The tread (30) comprises two wing portions (311, 312) and a middle portion (32). These elements rest on a base layer (33) located radially inside the tread (30). The base layer (33) comprises lateral portions (331, 332) in partial contact with the tread wings (311, 312). According to the invention, such a crown structure of the tire in contact with the carcass reinforcement contributes to constituting a superior conduction path of the electric charge between the rim and the ground when the tire is mounted on the rim and applied to the ground.)
