摘要： The tire (70) of the invention incorporates a carcass ply cord material (93) with variable modulus of elasticity to provide an active sidewall structure (82a, 82b). The variable modulus cord material is incorporated in the axially outwardmost ply (90) of a carcass (80) having two plies (88, 90) separated by elastomeric inserts (89a, 89b) in the sidewalls (82a, 82b). The outer ply cord material (93) provides an increased modulus of elasticity with an increase in elongation. The inner ply cords (91) have a modulus that substantially exceeds that of the outer ply cords (93) under normal loads in the inflated mode. Thus, the inner ply (88) dominates the structural response of the sidewalls (82a, 82b) at normal loads in the inflated mode. Under severe sidewall deflection, such as when the tire is uninflated, the outer ply cord (93) is elongated, increasing its modulus of elasticity and thus, shifting the load from the axially inwardmost ply (88) to the axially outwardmost ply (90).
摘要翻译： 本发明的轮胎（70）包括具有可变弹性模量的胎体帘布层帘线材料（93），以提供活性侧壁结构（82a，82b）。 可变模量帘线材料结合在具有由侧壁（82a，82b）中的弹性体插入件（89a，89b）分开的两层（88,90）的胎体（80）的轴向最外层（90）中。 外层帘线材料（93）随着伸长率的增加而提供增加的弹性模量。 在充气模式的正常负载下，内层帘线（91）的模量基本上超过外帘布帘线（93）的模量。 因此，在充气模式中，正常负载下，内层（88）支配侧壁（82a，82b）的结构响应。 在严重的侧壁偏转下，例如当轮胎未膨胀时，外帘线（93）是细长的，增加其弹性模量，因此将负载从轴向最内层（88）移动到轴向最外层（90） 。

摘要： A pneumatic radial ply runflat tire 1000 for a vehicle has a tread 1012, a carcass 1022 comprising at least one radial ply 1030 and two sidewalls 1016 each reinforced by a circumferentially disposed crescent-shaped wedge insert. Each insert has an elastomeric porous section 1042 embedded in an elastomeric stiffer layer 1044 of the insert 1040. When the tire is normally inflated, the porous section 1042, and hence the insert as a whole, is flexible, thereby providing comfortable driving characteristics. Under runflat (deflated tire) conditions, the pores in the porous section 1042 collapse, and the porous section 1042 stiffens, and hence the insert as a whole becomes stiff enough to support the load of the vehicle.

摘要： A pneumatic radial ply tire incorporating a crown reinforcing structure comprises at least one reinforcing hoop located approximately on the equatorial plane and disposed radially inward of the tread and radially outward of the carcass structure. The hoop is surrounded or encased by a layer of elastomeric transition material providing a flexible structural connection between the hoop and the adjacent carcass structure and belt structure. The hoop may have a substantially lenticular shape, or a complex shape with two thickened sections or lobes connected by a thin waist-like section, or a shape and a location that is asymmetric with respect to the equatorial plane of the tire, and may be made by winding a thin strip of material such as UHMWPE in an elastomeric matrix. The hoop may replace the belt structure of the tire.

摘要： A pneumatic radial ply runflat tire (200) has a tread (210), belt structure (212), a carcass (216), and an underlay (234) disposed between the belt structure and the carcass. The carcass (216) comprises two sidewalls (226), two beads (220), and one or more radial plies (222,224). The tire (200) is characterized by the underlay (234) having reinforcement cords (236) with turns aligned parallel to the tire's equatorial plane, the cords (236) exhibiting negligible modulus of elasticity (“modulus”) below a threshold elongation and high modulus above the threshold elongation. The underlay (234) stiffens the tire during runflat operation but not during normal inflated operation.

摘要： A self-supporting pneumatic tire, capable of continued operation during under-inflation conditions, has at least one insert located in each tire sidewall. Forming the interior surface of the self-supporting tire is a stiffening layer of material having characteristics similar to that of the insert. In the tread region of the tire, and radially inward of the innermost carcass layer, and possibly in the interior bead region of the tire, is a partial inner liner layer of the bromobutyl rubber.
