The invention relates to a self-sealing tyre for vehicle wheels, comprising at least one carcass ply (3), a crown (7) applied in a crown portion in a radially outer position relative to the carcass ply, at least one liner (9) applied in a radially inner position relative to the carcass ply, a seal assembly (10, 11) applied in a radially inner position relative to the liner and extending axially at least at a portion of the crown portion; wherein the sealing assembly comprises a permanent self-supporting elastomer layer (11) having an elongation modulus at 10% of less than 0.8 MPa and a sealing material layer (10) associated with and supported by the permanent self-supporting elastomer layer, the self-supporting elastomer layer being obtained by vulcanization of an elastomer compound having a Mooney ML (1 + 4) viscosity of less than 30; wherein the self-supporting elastomeric layer is radially inward of the layer of sealing material and the layer of sealing material is placed substantially in contact with the liner.

    本发明涉及用于车辆车轮的自密封轮胎,其包括至少一个胎体帘布层(3),相对于所述胎体帘布层在径向外部位置在冠部分中施加的胎冠(7),相对于所述胎体帘布层在径向内部位置施加的至少一个衬里(9),相对于所述衬里在径向内部位置施加并且至少在冠部分的一部分处轴向延伸的密封组件(10,11);其中所述密封组件包括在10%下的伸长模量低于0.8MPa的永久自支撑弹性体层(11)和与所述永久自支撑弹性体层相关联并由所述永久自支撑弹性体层支撑的密封材料层(10),所述自支撑弹性体层通过门尼ML(1+4)粘度低于30的弹性体胶料的硫化获得;其中所述自支撑弹性体层在所述密封材料层的径向内部并且所述密封材料层被放置成基本上与所述衬里接触。
