Abstract: Improvements are disclosed regarding the way in which vehicle wheels are designed and assembled, including ultralight, airless vehicle wheels adapted for mounting on a rim to receive a tire. One or more flexible ring-shaped tendons are disposed over the rim. A stuffer component is disposed over the tendons, and the wheel is disposed over the stuffer. A cover is bolted onto the rim holding the stuffer and tendons in position. Importantly, the tendons, stuffer and cover are all installed onto the rim from the outside toward the vehicle, thereby easing installation and maintenance. The invention may be adapted for all-terrain vehicles, and the wheel may have diameter on the order of 7 inches, 14 inches, or any other appropriate dimensions.

Abstract: NPR (negative Poisson's ratio) components for vehicle and other applications generally assume a tubular structure defining an axis, a length and a cross section. The structure is composed of a plurality of nested, double-V unit cells, each unit cell comprising a pair of side points A and B defining a width, a first pair of tensile members interconnecting points A and B and intersecting at a point C forming a first V shape, a second pair of stuffer members interconnecting points A and B and intersecting at a point D forming a second V shape. The unit cells are connected in a first direction with the point B of one cell being connected to point A of an adjoining cell, and so on, until completing a continuous band. The unit cells are further connected in a second direction with the point D of one cell being connected to point C of an adjoining cell. In one embodiment, the bands are stacked radially outwardly from the axis to form a bushing. In accordance with a second embodiment, the bands are stacked lengthwise along the structure to form a joust bumper.

Abstract: An auxetic wheel according to the invention comprises a line defining an axis of rotation; and a plurality of concentric rings of unit cells surrounding the axis, each unit cell being constructed of a plurality of members defining a Negative Poisson's Ratio (NPR) structure. The outermost ring of unit cells is arranged to facilitate rolling terrain contact, such that the stiffness of the structure in the localized region of loading due to terrain contact increases as the wheel rotates. A layer of material may be disposed between the concentric rings of unit cells which in preferred embodiments comprise a plurality of nested-V shapes. A cover may be provided over the outermost ring of unit cells forming a tire which may, or may not, be inflated.
