Problems solved by technology

Although this method can effectively reduce the cavity noise of the tire, when the tire is punctured and the tire is polished and repaired, it is necessary to remove the original sound-absorbing cotton layer pasted on it, which will cause irreversible damage to the sound-absorbing cotton layer.

experiment example 1

[0038] Experimental example 1: Tire B, the specification is 215 / 55R17: the width of the sound-absorbing cotton is 50% of the width of the inner wall of the sidewall, the lower side of the sound-absorbing cotton is 20mm from the edge of the tire toe, the thickness of the sound-absorbing cotton is 8mm, and there are no sound-absorbing holes on the sound-absorbing cotton.

experiment example 2

[0039]Experimental example 2: Tire C, the specification is 215 / 55R17: the width of sound-absorbing cotton 141 is 65% of the width of the inner wall of the sidewall, the lower side of the sound-absorbing cotton is 20mm from the edge of the tire toe, and the thickness of the sound-absorbing cotton is 8mm. No sound-absorbing holes are displayed on the sound-absorbing cotton.

Abstract

The invention belongs to the technical field of tires, and particularly relates to a repairable mute tire. The repairable mute tire comprises a tire body, wherein the tire body comprises a tire face portion, a tire bead portion and a sidewall portion, the sidewall portion is connected with the tire face portion and the tire bead portion, and the repairable mute tire is characterized in that strip-shaped sound absorption cotton is arranged on the inner wall of the sidewall portion in the circumferential direction, and the sound absorption cotton can keep original sound absorption performance during the tire is repaired. According to the repairable mute tire, the sound absorption cotton is arranged in the circumferential direction of the inner wall of the sidewall portion, so that the repairperformance after the tire is punctured is realized while the tire is reduced in noise; the sound absorption cotton on the side wall will not be damaged during the repair process of the tire puncturing, after the punctured tire is repaired, the original sound absorption can still be kept, the use cost of a user is reduced, and the market competition rate of products is increased.

Description

technical field [0001] The invention belongs to the technical field of tires, in particular to a repairable silent tire. Background technique [0002] In recent years, with the popularity of automobiles, consumers have put forward higher requirements for the comfort of automobiles, among which the reduction of tire cavity resonance noise is a very important indicator. The tire cavity resonance noise is the noise caused by the resonance of the ultra-low pressure sound system composed of the tire and the disc wheel, which is excited by the input of the road surface. It is also commonly called tire resonance noise. The frequency of cavity noise is between 200-300Hz, which is determined by the structure of the tire cavity. During the driving process, the resonance frequency of the cavity will be separated into two, resulting in two sharp peaks, and the resulting sound pressure will press the eardrum, bringing a very uncomfortable feeling to the driver and passengers.
