摘要:
Disclosed is a pneumatic run-flat tire. The tire (10) has at least one carcass reinforcing ply (12), at least one pair of sidewall wedge inserts (20), and a belt reinforcing structure. The belt reinforcing structure is formed from at least a pair of cross cord belt reinforcing plies (22, 24). Located radially outward of the carcass reinforcing ply (12) is a porous elastomeric layer (26). The porous elastomeric layer preferably has a porosity level of 20 to 80%, more preferably 40-70%, of the total volume of the porous elastomeric layer.
摘要:
A pneumatic tire (10) has a single carcass ply (12), at least one belt ply (24) disposed radially outward of the carcass ply in a crown portion of the tire, and at least one insert (20) located adjacent the carcass ply (14) in a sidewall portion, the insert providing support for the tire load to enable the tire to operate in underinflated conditions. The carcass ply comprises at least one composite cord (30). The composite cord is formed of at least two first yarns twisted helically about at least one second yarn. The first yarns and the second yarn having different modulus of elasticity, the first yarns (34) having a modulus greater than the modulus of the second yarn (32).
摘要:
By mixing a hydrophilic polymer into an elastomer matrix, elastomers loaded with hydrophilic polymer are prepared which have unique properties. In the illustrated method, a hydrophilic polymer is mixed with an elastomer base polymer. In one embodiment, the hydrophilic polymer forms fibers in a resulting elastomeric matrix. A base elastomer matrix interspersed with hydrophilic polymer made according to the invention can be used in reinforced elastomeric products such as tires.
摘要:
A pneumatic radial ply tire (10) comprising a bead (14) with an associated chafer (28); a carcass ply (12) folded about the bead (14) so as to define a main body portion (16) and a turnup portion (18) associated with the bead (14); a tread (24) disposed radially outward from the carcass ply (12), the tread (24) having a shoulder portion disposed at axial outer edges of the tread (24); and a sidewall (26) extending radially outward from the chafer (28) to a location adjacent the shoulder portion, the sidewall (26) being disposed axially outward of the carcass ply (12); wherein the sidewall (26) comprises a first outer layer (51) extending from the chafer (28) to the shoulder portion and a second inner layer (52) extending from the chafer (28) to the shoulder portion, the second inner layer (52) being disposed entirely between the carcass ply (12) and first outer layer (51), the second inner layer comprising a foamed structure of a rubber composition having a density ranging from 0.1 to 1.0 g/cm 3 .
