An improved spoke for a tire attaching an outer tread to a hub, the spoke having a spoke element possessing spoke element reinforcements, the spoke element joined by a joint body comprised of an elastomer connecting the spoke element to an outer compliant band where the joint body possesses an aperture so as to reduce the weight and hysteresis of the spoke.

A non-pneumatic wheel having a hub, an outer tread band and a plurality of spokes connecting the hub with the outer tread band, each of the plurality of spokes having first and second spoke elements joined by a body comprised of an elastomer connecting the first spoke element to the second spoke element.

A non-pneumatic tire includes a lower ring having a first diameter and an upper ring having a second diameter greater than the first diameter. The upper ring is substantially coaxial with the lower ring. The non-pneumatic tire further includes support structure extending between the lower ring and the upper ring. The non-pneumatic tire also includes an upper sidewall having an annulus shape that covers a portion of a first side of the support structure. The upper sidewall has an inner diameter that is greater than the first diameter.

A wheel assembly for a tire includes a circular hub member for securing to a rotatable axle of a vehicle, a first rim piece for engaging the hub member, a second rim piece for engaging the first rim piece, and a plurality of cylindrical sleeves for engaging both the first rim piece and the second rim piece. The first rim piece has cylindrical first shafts each engaging a first end of one of the sleeves. The second rim piece has cylindrical second shafts each engaging a second opposite end of one of the sleeves. An outer cylindrical surface of each sleeve engages a separate and distinct part the tire.

In a non-pneumatic tire, an outer ring comprises a laminate having a plurality of fiber layers, and at least one elastomer layer interposed between an adjacent pair of a plurality of fiber layers, the plurality of fiber layers include an outermost layer which among the plurality of fibers is that which is arranged in outwardmost fashion in a tire radial direction, and an innermost layer which among the plurality of fibers is that which is arranged in inwardmost fashion in the tire radial direction, and at least one of the outermost layer and the innermost layer contains a first fiber array at which fibrous material is arrayed so as to extend in the long direction of a joint.

This non-pneumatic tire is provided with a tread ring, a wheel which is arranged radially inside of the tread ring, and spokes which are interposed between the tread ring and the wheel. Further, the wheel has a disc part to which the vehicle shaft is linked, and a rim part which is connected on the inner peripheral side to the disc part and is joined on the outer peripheral side to the spokes. In this configuration, the average thickness (T1) of the disc part is set to be greater than the average thickness (T2) of the rim part. In other words, the relation T1>T2 holds.

A non-pneumatic tire and wheel assembly which includes a rim, and a spoke ring structure having an inner ring that is mounted on an outer surface of the rim. The inner ring has one or more retention nubs aligned for reception in complementary shaped grooves on the outer surface of the rim, wherein the spoke ring structure has a plurality of spoke members, and an outer tread ring is mounted on the outer circumference of the spoke ring.

An embodiment wheel includes a frame configured to rotate about an axial direction, an absorber coupled to a side of the frame in a radially outward direction, and a connector connecting the absorber and the frame, wherein a first portion of the connector is configured to be movable along the radially outward direction and a radially inward direction of the frame, and a second portion of the connector is configured to be rotatable on a plane that crosses the axial direction.

A method for manufacturing (S) a subassembly (3) for a tire (4) comprising the following substeps: providing an assembly comprising a supporting structure (14) comprising supporting filamentary elements linking a first structure (10) of filamentary elements and a second structure (12) of filamentary elements, aligning (S1) the first structure (10) and the second structure (12), securely fixing (S4) the first structure (10) onto the second structure (12) using a securing element (18), and cutting (S5) the assembly (1) along the securing element (18) so as to separate said securing element (18) from the rest of the assembly (1) and to obtain at least one subassembly (3) without securing element (18).

This non-pneumatic tire is provided with a tread ring, a wheel which is arranged radially inside of the tread ring, and spokes which are interposed between the tread ring and the wheel. Further, the wheel has a disc part to which the vehicle shaft is linked, and a rim part which is connected on the inner peripheral side to the disc part and is joined on the outer peripheral side to the spokes. In this configuration, the average thickness (T1) of the disc part is set to be less than the average thickness (T2) of the rim part. In other words, the relation T1<T2 holds.
