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.
本发明公开了一种静音结构轮胎,包括胎冠部、设在胎冠部两侧的胎侧部以及胎圈部,胎冠部由胎面层、冠带层、带束层、胎体层、气密层和静音构造层组成,胎面层、冠带层、带束层、胎体层、气密层和静音构造层从上至下依次设置,静音构造层中设计有静音孔;与传统轮胎有所不同的是,轮胎内增加有橡胶半部件静音构造层,能降低轮胎的空腔噪音,静音构造层与轮胎一体硫化生产,同时因不需进行轮胎内部气密层打磨、粘覆吸音材料的后处理程序,减少轮胎因打磨气密层造成的漏气风险,另外由于取消后续粘覆吸音材料的加工工序,降低了人员、设备投入,提升轮胎的生产效率。
