    • A non-pneumatic tire is provided with an annular reinforcing web that reduces the bending of compression spokes formed in the tire and reduces stresses and strains in the tire. The non-pneumatic tire includes an inner hoop member having an inner surface that defines the inner diameter of the tire, and an outer hoop member having a tread groove region that defines the outer diameter of the tire. A disc-shaped central web portion connects the inner and outer hoop members. A plurality of elongated, radially aligned cavities on either side of the central web defines integrally-formed compression spokes which connect the inner and outer hoop members. The annular reinforcing web is located on and affixed to either side of the central web portion and interconnects a mid portion of each spoke to a mid portion of the spokes on either side of it. Preferably, the annular reinforcing web is reinforced with fiber webbings on its outer side for added strength. The annular reinforcing web allows the tire to be made with less polyurethane material with no reduction in load carrying capability.
    • 非充气轮胎设置有环形增强腹板,其减小了形成在轮胎中的压缩轮辐的弯曲并且减小了轮胎中的应力和应变。 非充气轮胎包括具有限定轮胎内径的内表面的内箍构件和具有限定轮胎外径的胎面花纹沟区域的外箍构件。 盘形中心腹板部分连接内圈和外圈构件。 在中央腹板的任一侧上的多个细长的径向排列的空腔限定了连接内圈和外圈构件的一体形成的压缩轮辐。 环形加强腹板位于并固定在中心腹板部分的任一侧上,并将每个轮辐的中部部分互连到其任一侧上的轮辐的中部。 优选地,环形增强腹板在其外侧上用纤维网加固,以增加强度。 环形增强腹板允许轮胎由较少的聚氨酯材料制成,而不会降低承载能力。
