| description | The invention discloses a noise reduction pneumatic tire and relates to tire field. The noise reduction pneumatic tire is simple in structure, the tip parts of wedge sound absorption pieces fixed in acavity of the tire are matched with the air characteristic impedance; through the wedge forms of the sound absorption pieces, under the condition that the projection areas are the same, the effectivesound absorption areas of the sound absorption pieces are increased, the heights of the wedge sound absorption pieces accounts for a large proportion of the radial height of the tire cavity; the effect of isolating the mode is achieved in the cavity of the tire; the dispersion of cavity energy is realized; meanwhile, the sound absorption pieces are uniformly arranged in the tire at intervals; onone hand, the material consumption of the wedge sound absorption pieces is reduced; therefore, the weight of the tire is reduced, on the other hand, the hardness, the flexibility and other propertiesof the tire are not obviousl |
