The present invention discloses a type of secure and efficient wheel assembly using fluid or solid stuffing materials so as to minimize the blowout risks, a wheel rim transmission assembly, an energy exchanging arrangement used in transporting system, and a vehicle energy storage system, as well as corresponding methods for manufacturing and preparing such assemblies and arrangements in applications.

A tire including a tire frame member, a reinforcing layer, and projections. The tire frame member is circular and is formed from a resin material, and includes a bead portion, a side portion, and a crown portion. The reinforcing layer is provided at a tire radial direction outer side of the crown portion, and comprises a reinforcing cord extending in a direction intersecting the tire width direction, the reinforcing cord being covered by rubber. The projections are respectively formed at both tire width direction sides of the crown portion such that the reinforcing layer is interposed between the projections. Each projection projects toward the tire radial direction outer side, and includes a projection wall face contacted by a side face of the reinforcing layer at the tire width direction inner side of the projection.

Provided is a tire including: a tire frame member that is made of a resin and that has bead portions and side portions continuously extending on a tire radial-direction outer side of the respective bead portions; and a reinforcing layer that contains organic fibers and a resin material coating the organic fibers, in which tire the organic fibers include: a cord member containing a nylon fiber material; and an adhesive layer that is arranged on the cord member and formed from a resorcinol-formaldehyde resin-containing composition.

A tire which is formed of a resin material, is highly elastic, has a low loss factor, and has excellent heat resistance and fracture characteristics. A tire 10 has a circular tire case 17 that is formed of a resin material including a polystyrene-based resin and a resin having compatibility with polystyrene and having a glass transition temperature (Tg) higher than that of polystyrene.

A tire is provided with a tire frame member that is made from resin and includes: a bead portion; a side portion that is connected to an outer side of the bead portion in a tire radial direction and that has hole portions formed at intervals in a tire circumferential direction; and a crown portion that is connected to an inner side of the side portion in a tire width direction and that has a tread disposed thereon.

Provided are: a tire including: a tire frame; and a reinforcing metal cord member that is wound at least on the outer circumference of the tire frame, wherein at least a portion of the reinforcing metal cord member is coated with a coating composition via an adhesion layer that contains a polyamide-based adhesive and has a melting point of from 160 C. to 200 C., the coating composition containing at least one thermoplastic material selected from polyamide-based thermoplastic resins having a melting point of from 160 C. to 240 C. and polyamide-based thermoplastic elastomers having a melting point of from 160 C. to 240 C.; and a method of producing the same.

A tire includes: a ring shaped tire frame member that is made of a resin with plural tire pieces joined along a tire circumferential direction; a joint portion reinforcing belt that is adhered to the tire frame member, that extends around the tire circumferential direction, and that covers a joint portion of the plural tire pieces; and a tread layer that is provided further to the tire radial direction outside than the tire frame member and the joint portion reinforcing belt.

A tire includes: a tire case serving as an example of a circular tire frame member that is formed using a frame resin material; and a reinforcing cord member that is disposed at an outer circumference of the tire case, that is configured by a reinforcing cord covered with a resin covering layer, that is wound along a tire circumferential direction so as to form a spiral shape, that is bonded to the tire case, and in which tire axial direction adjacent portions of the reinforcing cord member are bonded together.

A tire includes: a tire frame member formed in a ring shape from a frame resin material, and including a pair of bead sections, a pair of side sections, and a crown section; a ring shaped bead core that is embedded in and joined to each of the bead sections, and that is formed by a single strand, or plurality of strands, of bead cord extending in the tire circumferential direction, and covered with, and joined to, a covering resin material; and an extension portion that extends from each of the bead cores in a direction that intersects with the tire circumferential direction when viewed from a tire side face, and that is joined to the tire frame member.

A tire has a cap rubber formed of a nonconductive rubber and forms a ground surface, and a conductive portion provided in at least one side end portion of a pair of side end portions in both ends in a tire width direction. The conductive portion is formed of a conductive rubber, and reaches a side surface of the cap rubber from the ground surface through an inner portion of the cap rubber. The conductive portion is the smallest in thickness in the ground surface, is relatively large in thickness in the side surface of the cap rubber, is gradually increased in thickness from the ground surface to the side surface of the cap rubber, and is formed into a trumpet shape which is curved into an inner side in a tire width direction and an inner side in a radial direction, in a tire meridian cross section.
