The invention relates to the technical field of tires, in particular to a high-trafficability low-noise tire which comprises a first circumferential main groove, a second circumferential main groove, transverse main grooves and transverse auxiliary grooves. The circumferential main grooves extend in a continuous angular bending mode in the circumferential direction of the tire, and the two circumferential main grooves are symmetric about the point center of the center line of the driving face. The transverse main grooves are continuously and angularly bent and extend in the width direction of the tire groove to be communicated with the circumferential main grooves, the transverse main grooves are non-uniformly distributed in the circumferential direction of the tire, and the circumferential distance between every two adjacent transverse main grooves is 70-140 mm; the transverse auxiliary grooves are continuously and angularly bent from the circumferential main grooves and extend to the tire side, and are arranged between two adjacent transverse main grooves; fusiform pattern blocks are formed between the circumferential main grooves and the two adjacent transverse main grooves; each fusiform pattern block is provided with a first branch groove and a second branch groove which extend in a crossed manner, the branch grooves are continuously and angularly bent and extend to divide the fusiform pattern blocks into centrosymmetric patterns, the first branch grooves are communicated with the circumferential main grooves, and the second branch grooves are communicated with the transverse main grooves. And high trafficability and low noise are achieved.
本发明涉及轮胎技术领域,尤其涉及一种高通过性低噪音轮胎,包括:第一周向主槽、第二周向主槽、横向主槽和横向副槽;周向主槽沿轮胎周向连续角形弯曲延伸,两条周向主槽关于行驶面中心线的点中心对称;横向主槽沿轮胎槽宽方向连续角形弯曲延伸与周向主槽连通,横向主槽沿轮胎周向非均匀排布,相邻横向主槽之间的周向距离为70~140mm;横向副槽自周向主槽连续角形弯曲延伸至胎侧,且设置在两条相邻的横向主槽之间;周向主槽和两条相邻的横向主槽之间形成梭形花纹块;梭形花纹块设置有交叉延伸的第一支槽和第二支槽,支槽连续角形弯曲延伸将梭形花纹块分割成中心对称图形,第一支槽连通周向主槽,第二支槽连通横向主槽。兼具高通过性和低噪音。
