A method of making a non-pneumatic tire, the non-pneumatic tire comprising a ground contacting annular tread portion comprising a tread rubber composition, a shear band comprising a cord reinforced rubber composition and disposed radially inward of the tread portion, and at least one spoke disk disposed radially inward of the shear band; wherein the spoke disk has an outer ring, and an inner ring, and a first and second spoke extending radially between the outer ring and the inner ring, wherein the first and second spokes are connected at a joint; the method comprising the steps of: applying a curable adhesive as an interface between a radially outermost surface of the spoke disk and a radially innermost surface of the shear band in its uncured state; assembling the tread portion in an uncured state, the shear band in an uncured state, and the at least one spoke disk to form an pre-assembly; and curing the pre-assembly.

A non-pneumatic tire (1) includes three or more tubular bodies (2) and a plurality of elastically deformable connecting members (3) interconnecting the tubular bodies (2) and disposed along a tire circumferential direction in each annular space (9) provided between the tubular bodies (2) adjacent to each other in a tire radial direction. The tubular bodies (2) are provided with an inner tube (6) positioned on an innermost side in the tire radial direction and attached to an axle, an outer tube (4) positioned on an outermost side in the tire radial direction, and an elastically deformable intermediate tube (8) positioned between the inner tube (6) and the outer tube (4). The connecting member (3) is provided with a pair of connecting plates (21 and 22) having both end portions in the tire radial direction directly connected to the tubular body (2) and extending in the tire radial direction and separated in the tire circumferential direction from an outside toward an inside in the tire radial direction. A position (P1) of connection to the pair of connecting plates (21 and 22) connected to the intermediate tube (8) from the outside in the tire radial direction and a position (P2) of connection to the pair of connecting plates (21 and 22) connected to the intermediate tube (8) from the inside in the tire radial direction are shifted in the tire circumferential direction in the intermediate tube (8).

A tire for a mobile vehicle includes an outer flexible ring mounted to an inner central rim and a spoke structure extending radially between the inner central rim and the outer flexible ring. The spoke structure is constructed from a plurality of elements disposed side-by-side such that the elements extend circumferentially around the perimeter of the inner central rim and radially inside the outer flexible ring. The spoke structure further defines a plurality of triangular openings disposed between the outer flexible ring, a first element of the plurality of elements and a second element of the plurality of elements. The first element is circumferentially adjacent the second element.

In a non-pneumatic tire, the plurality of connecting portions comprise first connecting portions extending in such fashion as to be directed from a first side in a tire width direction of an inner annular portion toward a second side in the tire width direction of an outer annular portion, and second connecting portions extending in such fashion as to be directed from the second side in the tire width direction of the inner annular portion toward the first side in the tire width direction of the outer annular portion, and at least one of the plurality of connecting portions comprises a main body portion having a width that is constant or that increases in tapered fashion by a constant ratio as viewed in the tire width direction, and an reinforcing portion that connects an end in a tire circumferential direction of the main body portion and the annular portion.

The invention is directed to a process for the production of at least a part of a non-pneumatic tire structure, the non-pneumatic tire structure comprising an inner band, an outer band surrounding the inner band and a spoke part comprising a plurality of spokes extending between the inner band and the outer band; wherein the process comprises providing a first plastic composition in the form of a filament comprising a continuous fiber coated with a first thermoplastic resin; and forming one or more selected from one or more spokes of the plurality of spokes, the inner band and the outer band of the non-pneumatic tire structure by 3D printing, wherein forming includes depositing layers of the first plastic composition.

A wheel for a vehicle, such as a forklift (e.g., an electric forklift) or another material-handling vehicle, in which the wheel comprises a tire (e.g., a non-pneumatic tire) and may be designed to enhance its use and performance and/or use and performance of the vehicle, including, for example, to exhibit less rolling resistance, be more energy-efficient and/or allow the vehicle to travel faster and/or with improved ride comfort. For instance, elastic deformation of the wheel as it rolls may be better managed (e.g., reduced), which may improve thermal behavior of the wheel and/or may be combined with ways to better distribute or dissipate heat (e.g., by increasing thermal conductivity).

A rim for a non-pneumatic tire comprises a cylindrical rim wall portion, and a fixing member disposed to be spaced apart from the rim wall portion in a radial direction. The rim wall portion is provided with a fixing protrusion protruding in the radial direction or a fixing groove depressed in the radial direction.

A non-pneumatic tire assembly includes a non-pneumatic tire. The non-pneumatic tire includes an inner circumferential ring and an outer circumferential ring defining an annular space and a cylindrical space inside the inner circumferential ring. A plurality of partitions connect the circumferential rings within the annular space. A ground-contacting tread is located on the outer circumferential ring. A rim, including a plurality of pieces, is located within the cylindrical space. The non-pneumatic tire assembly further includes a hub that is removably connected to the rim.

A non-pneumatic tire includes a plurality of axially adjacent wheel portions. Each wheel portion has an inner ring, an outer ring, and a flexible, interconnected web extending between the inner ring and the outer ring. The flexible, interconnected web includes a plurality of web sectors disposed circumferentially about the tire to form a generally annular web. Each of the plurality of web sectors is hingedly connected to a pair of oppositely adjacent web sectors.

A tire and wheel assembly includes a non-pneumatic tire and a wheel. The non-pneumatic tire has a tread, a plurality of spokes, and an inner liner with a first side, a second side, and at least one taper extending between the first side and the second side. The wheel has an inboard side, an outboard side, and an outer surface with at least one complimentary taper extending between the inboard side and the outboard side such that the non-pneumatic tire is serviceably mounted on the wheel. A locking ring can be included and the locking ring can be configured to abut against the inboard side or the outboard side of the wheel. Also, a wheel flange extending inwardly from the inner liner can be included and the wheel flange is configured to abut against the outboard side or the inboard side of the wheel.
