Abstract: A wheel assembly includes a rigid wheel and an airless flexible tire with certain performance characteristics of a pneumatic tire. The rigid wheel includes a central portion and a plurality of circumferentially spaced mounting elements removably attached to a radially outer margin of the central portion. The tire is mounted on the wheel and engages the mounting elements such that portions of the tire not engaging the mounting elements are separated radially from the wheel by a space. The tire is configured such that portions of the tire not engaging the mounting elements flex inwardly toward the wheel when subject to ground engaging pressure, thereby minimizing ground penetration and soil disruption. The tire may include one or more tension elements embedded in the tire to increase the tire's strength and resilience.

Abstract: A wheel assembly including a rigid wheel having a radially outer rim wall presenting a polygonal shape with a plurality of outermost vertices connecting a plurality of planar faces, and a flexible tire mounted on the outer rim wall. The tire is supported by the vertices of the rim wall and is separated from the rim faces by a space, portions of the tire located between the vertices being configured to flex inwardly when subject to ground engaging pressure.

Abstract: A wheel assembly including a rigid wheel and a flexible tire. The rigid wheel includes a radially outer rim wall, a plurality of mounting elements, and a plurality of inflatable spacers between the mounting elements. The flexible tire may be mounted on the mounting elements of the rigid wheel such that portions of the flexible tire between the mounting elements are separated from the outer rim wall by spaces between the mounting elements and are configured to flex inwardly when subject to ground engaging pressure. The inflatable spacers limit the amount of inward flex of the inwardly flexible portions of the flexible tire.
Abstract translation: 一种包括刚性轮和柔性轮胎的轮组件。 刚性轮包括径向外缘壁，多个安装元件和在安装元件之间的多个可充气间隔件。 柔性轮胎可以安装在刚性轮的安装元件上，使得安装元件之间的柔性轮胎的部分通过安装元件之间的空间与外缘壁分离，并且构造成当受到地面接合压力时向内弯曲 。 可充气间隔件限制柔性轮胎向内挠性部分向内弯曲的量。
