Silence structure tire

Abstract

The invention discloses a silence structure tire which comprises a tire crown part, tire side parts arranged on the two sides of the tire crown part and a tire bead part, the tire crown part is composed of a tire tread layer, a cap ply, a belted layer, a tire body layer, an airtight layer and a silence structure layer, and the tire tread layer, the cap ply, the belted layer, the tire body layer, the airtight layer and the silence structure layer are sequentially arranged from top to bottom. Silence holes are designed in the silence structural layer. Different from a traditional tire, a rubber half part silence structure layer is additionally arranged in the tire, cavity noise of the tire can be reduced, the silence structure layer and the tire are integrally produced in a vulcanization mode, meanwhile, due to the fact that post-processing procedures of inner airtight layer polishing and sound absorbing material adhering in the tire do not need to be carried out, the air leakage risk caused by inner liner polishing of the tire is reduced, and in addition, the subsequent processing procedure of adhering the sound-absorbing material is cancelled, so that the investment of personnel and equipment is reduced, and the production efficiency of the tire is improved.

Description

technical field [0001] The invention relates to a tire, in particular to a tire with a silent structure. Background technique [0002] As consumers have higher and higher requirements for automobile performance, consumers are paying more and more attention to the cavity noise of tires. When the car is running, if the cavity noise of the tire is too loud, the sound pressure will oppress the eardrums of the driver and passengers, causing discomfort. Generally, a tire includes: a crown portion, a sidewall portion, and a bead portion; wherein the crown portion is composed of a tread layer, a cap layer, a belt layer, a carcass layer, and an inner liner. The common method at present is to reduce the cavity noise of the tire by sticking and covering the sound-absorbing material under the inner liner of the finished tire to increase the air vibration damping in the tire cavity. [0003] In the traditional method of sticking and covering sound-absorbing materials, under the conditi...

Problems solved by technology

[0003] The traditional method of sticking and covering sound-absorbing materials, under the conditions of high-speed rotation of tires, high ambient temperature, too low ambient temperature, and long-term use of tires, due to changes in the viscosity of the covering rubber material, it is easy to cause the sound-absorbing material to fall off or be damaged. It is also necessary to polish the inner liner of the tire to increase the stickiness of the rubber compound to the tire. The inner lining after grinding will be correspondingly thinner, and there is a risk of tire air leakage. In addition, the method of sticking the sound-absorbing material needs to be carried out on the finished tire. Additional processing, the increased production process needs to increase the input of personnel and equipment, and will also reduce the production efficiency of tires
