Abstract:
Ballistic resilient run-flat tire device (10), kit and a method for preparing a tire body for providing runflat capabilities such as to travel for a relatively long distance, for at least 30 miles at 30 miles per hour, after the device has been compromised as of result of exposure due to ballistic ordinance rifle shots or air loss from road hazard punctures; the device (10) includes a tire carcass (20) and a polyurethane inner coating (60) inside the tire carcass that defines a an inflatable hollow chamber within the ballistic resilient run-flat tire; the tire carcass (20) has an annular tread (30), a pair of sidewalls (40), and beads (50); the polyurethane inner coating (60) inside the tire carcass defining a hollow chamber provides additional protection along the sidewalls and tread of the tire carcass; the kit includes the un-interconnected elements of the device; the method includes the steps of curing, discharging, filling, injecting, introducing, mounting, obtaining, and preparing.
Abstract:
A pneumatic tire (10) incorporates a plurality of parallel-aligned, tread-stiffening support members (23) typically disposed laterally between the tread (12) and the ply structure (16). The support members (23) inhibit lateral and circumferential tread lift during runflat operation. Support members (23) can each be a monolithic rib (22) made of a fiber reinforced plastic material. An alternative layered rib (24) has two outer layers (40, 44) of a fiber reinforced plastic material while the central layer (42) is an elastomer.
Abstract:
A runflat radial ply pneumatic tire (10) having a carcass (30) reinforced with at least two sidewall fillers or inserts (42, 46) and at least one cord reinforced ply (38) and two bead cores (26) and one or more reinforcing belts (36). The at least one ply (38) reinforced with cords, the cords have a pair of turnup ends (32) wrapped around the pair of bead cores (26). The turnup ends (32) extend radially outwardly to a terminal end (33), the terminal end (33) being located under the reinforcing belts (36). The first insert (42) lies radially inward and adjacent the ply (38). The second insert (46) lies radially between the ply (38) and its turnup end (32). The tire (10) requires a reduced number of components and can be lighter in weight than the prior art runflat tires.
Abstract:
A runflat pneumatic tire (1, 2, 3, 4, 5 and 6) has a tread stiffening member (101) radially inward of the tread (12). The tire has a deflected section height H30 under load at 30 psi inflation and a deflected section height H0 at 0 psi wherein the deflection D30 are equal to or less than D0 - D30 and the net contact area at 0 psi has a perimeter dynamic contact of at least U shaped or rectangular.
Abstract:
A tire (10) has a composite ply (40). The composite ply (40) has a primary ply (40A) reinforced with parallel inextensible cords (41) and a pair of ply extensions (40B) having synthetic cords. The method of manufacturing the tire (10) is described. The tire (10) can be made as a runflat type tire.
Abstract:
Le pneumatique (10) adapté pour un roulage à plat comprend une armature de carcasse (32) comprenant au moins un élément de renfort (36) comprenant au moins un brin multifilamentaire (54) en aramide et au moins un brin multifilamentaire (56) en polyester retordus ensemble.
Abstract:
A pneumatic radial tyre superior in run-flat durability, comprising sequentially a belt layer (4) containing a plurality of layers of metal cords and a tread (5) on the circumference of a crown portion (3) of a toroidal radial carcass (2), and also a rubber reinforcement layer (7) having a crescent cross section and adapted to partially bear the load, on the inner circumferential surface of a side portion of the carcass, wherein organic fiber cords are disposed between the carcass and the belt layer, and wherein the organic fiber cord has an auxiliary layer (8) arranged in a direction in which it intersects the carcass and the belt layer with a central equator surface being interposed therebetween.
