    Abstract: A method of making a foam-filled tire wherein a resilient elastomeric foam is formed and cured within a tire carcass while the carcass interior is at super-atmospheric pressure. Such superatmospheric pressure is believed to support the cell walls against internally generated gas (blowing) pressures, thereby stabilizing the cells at higher than usual internal cell pressure. The foaming operation is carried out so that the foam only partially fills the carcass interior. After the elastomeric foam has been cured the tire carcass interior is depressurized down to the pressure to be used in service. During the depressurization process the internal cell pressures cause the cells to expand and further fill the tire interior space. The depressurization processis carried out after the elastomeric foam has been cured, i.e. when the cell walls have attained their full potential strength. Accordingly, the post-cure expansion of the cell walls does not result in cell wall rupture, even though the cell walls are relatively thin. The thin cell walls resulting from this process are advantageous in that they reduce the required mass of foam-forming elastomer, thereby achieving improvements in respect to lower raw material costs, shorter cure times, lesser non-useful dead loads, lesser heat build-up and foam degradation during service, and lesser tendency toward wheel imbalance.

    Abstract translation: 一种制造填充泡沫的轮胎的方法,其中弹性弹性体泡沫在轮胎胎体内形成并固化,同时胎体内部处于超大气压。 据信这种超大气压力支持细胞壁抵抗内部产生的气体(吹)压力,从而使细胞在高于通常的内部细胞压力下稳定。 进行发泡操作使得泡沫仅部分地填充胴体内部。 在弹性体泡沫已经固化之后,轮胎胎体内部被减压到使用中使用的压力。 在减压过程中,内部细胞压力导致细胞膨胀并进一步填充轮胎内部空间。 在弹性泡沫体固化之后,即当细胞壁达到其全部潜在的强度时,进行减压过程。 因此,细胞壁的后固化膨胀不会导致细胞壁破裂,即使细胞壁相对较薄。 由该方法产生的细胞细胞壁的优点在于它们减少了所需的泡沫形成弹性体的质量,从而在较低的原材料成本,较短的固化时间,较少的非有用的死载,较少的热积聚 在使用过程中泡沫降解,轮子不平衡倾向较小。
