摘要： In a preferred embodiment, the invention is a non-deflatable tire assembly having a hollow toroid-shaped flanged insert, a flexible body molded around the insert to form a tire, and at least one rim onto which is mounted the tire. The flange of the insert extends toward the central axis of the insert, and is used to attach the tire to the rim(s) via bolts through matching holes within the flange and rim(s). The flexible body may be made of a foam polyurethane matrix formed of a combination of polyol and polyisocyanate, while the flanged insert may be made of a high density polyethylene. A tough, flexible, and abrasive-resistant layer of polyurethane elastomer is preferably formed around the flexible body to define sidewalls and treads of the tire. To aid in the construction of the assembly and/or to better transmit torque and braking loads from an axle (to which the tire assembly is mounted) to the tire, mating protuberances and holes may be formed in the flange and the rim(s), the rims may be mounted to the tire with an interference fit, and/or the surface of the insert facing the flexible body molded around the insert may be ribbed. Optionally, and for light load conditions, the flange of the insert may extend to and be secured to the axle itself, omitting the need for rims in the tire assembly.
摘要翻译：在优选的实施例中，本发明是一种不可放气的轮胎组件，其具有中空的环形凸缘插入件，围绕插入件模制以形成轮胎的柔性体，以及至少一个边缘，轮胎上安装有该凸缘。插入件的凸缘朝向插入件的中心轴线延伸，并用于通过螺栓将轮胎连接到轮缘上，该凸缘通过法兰和边缘内的匹配孔。柔性体可以由多元醇和多异氰酸酯的组合形成的泡沫聚氨酯基质制成，而凸缘的插入物可以由高密度聚乙烯制成。优选地，在柔性体周围形成韧性，柔性和耐磨性的聚氨酯弹性体层，以限定轮胎的侧壁和胎面。为了有助于组件的构造和/或更好地将扭矩和制动载荷从轮轴（轮胎组件安装到轮胎上）传递到轮胎，可以在凸缘和轮辋中形成配合突起和孔，轮辋可以以过盈配合的方式安装在轮胎上，和/或插入物的面向柔性体的表面可以被嵌入。可选地，对于轻负载条件，插入件的凸缘可以延伸到轴本身并且固定到车轴本身，省略了对轮胎组件中的轮辋的需要。
