    摘要： A non-pneumatic tire (10) comprising a tread band having a ground engaging surface, a first reinforcement layer (250) comprised of at least one reinforcement (251) oriented in the tire's circumferential direction, a second reinforcement layer (254), located radially outward from said first reinforcement layer (250), said second reinforcement layer (254) comprised of a plurality of reinforcements oriented at an angle in a first direction to said tire's circumferential direction, a third reinforcement layer (258), located radially outward from said second reinforcement layer (254), said third reinforcement layer (258) comprised of a plurality of reinforcements oriented at an angle in a second direction to said tire's circumferential direction and a fourth reinforcement layer (262), located radially outward from said third reinforcement layer (258), comprised of at least one reinforcement oriented in the tire's circumferential direction.

    摘要： The present invention provides improved spoke edge geometry for a non-pneumatic or hybrid tire that is less prone to fatigue when used. The present invention also provides a way to manufacture such geometry in a mold, In particular the spoke edge geometry is provided with a reduced cross-section that reduces the bending stresses locally and allows a unique mold construction that changes the placement and orientation of potential flash and reduces other potential molding flaws when a liquid such as polyurethane is introduced into the cavity of the mold to form a spoke. This change results in a reduction in the possibility of a stress riser being found near the edge of the spoke, enhancing the durability of the tire.

    摘要翻译： 本发明提供了用于非气动或混合轮胎的改进的轮辐边缘几何形状，其在使用时不易疲劳。 本发明还提供了一种在模具中制造这种几何形状的方法。特别地，轮辐边缘几何形状具有减小的横截面，其局部减小了弯曲应力，并允许独特的模具结构，其改变了潜在闪光的放置和取向 并且当将诸如聚氨酯的液体引入模具的空腔中以形成辐条时，减少其它可能的成型缺陷。 这种变化导致在轮辐边缘附近发现应力提升器的可能性降低，从而提高了轮胎的耐久性。
