Embodiment Construction

[0050] According to the present invention, the pneumatic tire 3 has a toroidal hollow body including a tread portion 3t, a pair of axially spaced bead portions 3b, and a pair of sidewall portions 3s extending between the tread edge and the bead portions 3b. , The noise absorber 4 is set in the hollow body of the tire. Generally, the hollow body includes the following reinforcing structures: a bead core 11 provided in each bead portion 3b; a carcass 6 extending between the bead portions 3b through the tread portion 3t and the sidewall portion 3s; The belt layer 10 on the radially outer side of the carcass 6 in 3t.

[0051] The inner surface layer of the tire is made of an air-impermeable rubber compound. Usually, an inner liner 9 separate from the carcass 6 is provided to cover the inner surface 3i of the tire. However, it is possible to use the carcass topping rubber as the airtight rubber layer instead of using a separate innerliner.

[0052] In this embodiment, the pneuma...

Abstract

The present invention discloses a pneumatic tire having a noise damper, a method for manufacturing the same, and a method for fixing the damper to the tire. The inner surface of the tread portion of the vulcanized tire is buffed, and the noise damper is fixed to the buffed inner surface, using a double-sided adhesive tape which has specific characteristics such as adhesive force, tensile strength, thickness, cold-resistant property, heat-resistant property and water-resistant property.

Description

technical field [0001] The present invention relates to a method of manufacturing a pneumatic tire having a noise damper, and more particularly, to a method of fixing the noise damper to an inner surface of a vulcanized tire. Background technique [0002] In order to reduce tire noise generated during running, there is provided a noise damper made of a sponge material and disposed in a tire cavity, such as disclosed in Japanese Patent Application Publication No. 2003-063208. This noise absorber prevents or interrupts the resonance of the tire cavity, ie the vibration of the air filled therein. In addition, since the noise damper is adhered to the inner side of the tread portion, vibration of the tread portion can be reduced. [0003] During operation, the tread deforms so that portions of the footprint become flatter while the remainder is generally cylindrical for the most part. Therefore, the boundary between the flat portion and the cylindrical portion has a relatively ...
