- An object of the present invention is to provide a low-noise pneumatic tire that makes it difficult for the sound absorbing material on the inner peripheral surface of the tire to be damaged when the rim force is released from the pneumatic tire.
- the low-noise pneumatic tire of the present invention that achieves the above-mentioned object is provided on the inner peripheral surface of the sound-absorbing material, with the pneumatic tire having a sound-absorbing material that is a porous material on the inner peripheral surface of the tire. It is characterized in that a lubricant is applied to at least the regions at both ends in the tire width direction.
- Another low-noise pneumatic tire of the present invention that achieves the above object is a pneumatic tire in which a sound-absorbing material having a porous material force is attached to the inner peripheral surface of the tire.
- the both ends in the tire width direction are each covered with a protective layer harder than the sound absorbing material.
- the rim-assembled pneumatic tire is removed when the rim force is removed.
- damage to the sound absorbing material can be prevented by slipping the tip of the lever on the surface of the sound absorbing material.
- both ends of the inner circumferential surface of the sound absorbing material in the tire width direction are covered with protective layers harder than the sound absorbing material, so that the rim-assembled pneumatic tire is provided.
- the protective layer can relieve the strong pressing force from the lever of the tire changer and prevent the sound absorbing material from being damaged. Therefore, even if the pneumatic tire removed from the rim is reused, the stress absorption performance of the sound absorbing material can be maintained for a long time because there is no concentration of stress starting from the damaged portion and it is difficult to cause damage.
- FIG. 1 is a meridian cross-sectional view showing a state in which a rim of a low-noise pneumatic tire serving as an embodiment of the present invention is assembled.
- FIG. 2 is a meridian cross-sectional view showing a state in which a rim of a low-noise pneumatic tire as another embodiment of the present invention is assembled.

- FIG. 4 is a perspective view showing a partially broken sound-absorbing material having the power of another embodiment.
- FIG. 5 is a perspective view showing a conventional low-noise pneumatic tire with a part broken away.
- FIG. 6 is an explanatory view showing a cross section when the rim force of the low-noise pneumatic tire of FIG. 5 is also removed.
- FIG. 1 is a meridian cross-sectional view showing a state where a low-noise pneumatic tire, which is an embodiment of the present invention, is mounted on a rim.
- the pneumatic tire T has a tire body that is connected to a pair of sidewall portions 2 and 2 and a pair of bead portions 3 and 3 on the left and right of the tread portion 1 respectively.
- the tire body is provided with a carcass layer that forms the skeleton of the tire and a belt layer that gives rigidity to the tread portion.
- a sound absorbing material 5 is attached by elastic fixing bands 6 to the tire inner peripheral surface la of such a tire body.
- the sound absorbing material 5 is made of a band-shaped porous material, and is arranged in an annular shape so as to make one round of the tire inner peripheral surface la.
- the lubricant 4 is applied to the inner peripheral surface 5a of the sound absorbing material 5 over the entire surface.
- the tip of the lever of the tire changer is the sound absorbing material.
- the surface of 5 may be pressed.
- the lubricant 4 is applied to the surface of the sound absorbing material 5 in the pneumatic tire T, even if the lever X is pressed, the tip force S slips and damages the sound absorbing material 5. There is no. Therefore, even if the pneumatic tire is reused after being detached from the rim, the sound absorbing material is not damaged early, and good sound absorbing performance can be exhibited for a long period of time.
- the application region of the lubricant 4 to the sound absorbing material 5 may be at least both ends of the inner peripheral surface 5a in the tire width direction.
- the lubricant 4 is applied to the entire area of the inner peripheral surface 5a.
- Lubricant 4 should be applied not only to the inner peripheral surface 5a of the sound absorbing material 5 as described above but also to the outer peripheral surface side of the sound absorbing material 5.
- the type of the lubricant is not particularly limited, but examples include wax, graphite, molybdenum disulfide, boron, polytetrafluoroethylene, talc, silicone, liquid paraffin, mineral oil, and the like. Can do. These lubricants may be used alone or in combination of two or more.
- the above-mentioned waxes include natural waxes, fiber-tissue tropschs, hydrocarbon synthetic waxes such as polyethylene, and fatty acid ester-based lacquers. , Fatty acid amides, ketones, hardened castor oil, etc. can be used. As for these boxes, only one type may be used alone, or two or more types may be used in combination.
- FIG. 2 shows a state where a low-noise pneumatic tire, which is another embodiment of the present invention, is mounted on a rim
- FIG. 3 shows an elastic fixing for mounting the sound absorbing material mounted on the inner surface of the tire. Shown with the band.
- the pneumatic tire T in FIG. 2 has the same tire body as that in the embodiment in FIG. 1, and therefore the description of the tire body is omitted.
- the sound-absorbing material 5 has a belt-like porous material force as in FIG. 1, and the belt-like material is annularly formed so as to make one round of the tire inner circumferential surface la inside the tread portion 1.
- the inner peripheral surface 5a of the sound absorbing material 5 is covered with protective layers 7 and 7 at both ends in the tire width direction, and the protective layer 7 is a hard resin sheet having a hardness higher than that of the sound absorbing material 5. Or it consists of a metal sheet.
- the protective layer 7 may be provided on the sound absorbing material 5 as in the embodiment shown in FIG.
- both side surfaces of the sound absorbing material 5 are formed into inclined inclined surfaces 5b, 5b, respectively, and both the inclined surfaces 5b, 5b and both ends of the inner peripheral surface 5a in the tire width direction are the protective layers 7, 7, respectively. 7 may be covered.
- the rim-assembled pneumatic tire T is removed from the rim R using the tire changer.
- the tip of the lever X can be brought into direct contact with the surface of the protective layer 7 so that the sound absorbing material 5 is not damaged. Therefore, as in the embodiment of FIG. 1, the durability of the sound absorbing material 5 can be improved and good sound absorbing performance can be maintained over a long period of time.
- the protective layer 7 is not particularly limited as long as it has a higher hardness than the sound absorbing material 5 and is made of a hard material, but is preferably made of a resin sheet or a metal sheet. Good.
- the resin sheet material include polypropylene, polyethylene, polyester, and polyamide.
- the material for the metal sheet include steel and copper, and stainless steel is particularly preferable.
- the thickness of the protective layer is preferably 0.05 to: L Omm.
- the protective layer thickness is 0.
- the width of the protective layer in the tire width direction is preferably 10 to 40 mm. If the width of the protective layer is less than 10 mm, it will be difficult to prevent damage to the sound absorbing material due to contact with the lever tip. On the other hand, if it is larger than 40 mm, the covering area on the inner peripheral surface of the sound-absorbing material by the protective layer becomes too large and the sound-absorbing performance decreases.
- the lubricant used in the embodiment of FIG. 1 may be further applied to the tire cavity side surface of the protective layer 7.
- the slip change of the tire changer is promoted, so that the effect of preventing the sound absorbing material from being damaged by the protective layer can be further improved.
- the sound absorbing material 5 is attached to the tire inner circumferential surface la.
- the elastic fixing band 6 is disposed on the outer peripheral side of the sound absorbing material 5
- the elastic fixing band 6 may be disposed on the inner peripheral surface 5 a side of the sound absorbing material 5 and attached.
- the low-noise pneumatic tire of the present invention described above can be applied to pneumatic tires in general, but particularly when applied to a pneumatic tire having a flatness ratio of 45% or less that easily causes damage to the sound absorbing material. It can be effective.
- a common condition is that the tire size is 225Z40R18, and a 20 mm thick, 180 mm wide urethane foam sound-absorbing material is attached to the tire's inner peripheral surface with a 20 mm wide, 2 mm thick polypropylene resin band.
- a low-noise pneumatic tire coated with polyethylene wax on the inner peripheral surface of the sound absorbing material (Example 1), and a polypropylene bag having a width of 20 mm and a thickness of 0.5 mm on both ends of the inner peripheral surface of the sound absorbing material in the tire width direction.
- Low noise pneumatic tire coated with a grease sheet (protective layer) (Example 2)
