The invention discloses a low-noise tire which comprises a tire body and tread pattern blocks, the tread pattern blocks are arranged in the circumferential direction of the tire body, and the tread pattern blocks comprise center pattern blocks and center pattern blocks; the first side part pattern blocks and the second side part pattern blocks are arranged in a staggered manner; the first shoulder pattern block and the second shoulder pattern block are arranged in a staggered manner; and a partition strip. The first side pattern blocks and the second side pattern blocks are arranged in a staggered mode, different sound pressure amplitudes can be generated when the first side pattern blocks and the second side pattern blocks impact the ground at the same time, and sound energy superposition generated when the first side pattern blocks and the second side pattern blocks impact the ground is avoided. Meanwhile, the partition strips are arranged in the longitudinal grooves of the tire tread, the continuous longitudinal grooves can be partitioned, and continuous flow of air in the longitudinal grooves is blocked, so that noise generated when the air flows in the longitudinal grooves of the tire tread at a high speed is reduced.
本申请公开了一种低噪音轮胎,其包括:轮胎本体和胎面花纹块,胎面花纹块绕轮胎本体的周向设置,胎面花纹块包括:中心花纹块;第一侧部花纹块、第二侧部花纹块,第一侧部花纹块和第二侧部花纹块错位设置;第一肩部花纹块、第二肩部花纹块,第一肩部花纹块和第二肩部花纹块错位设置;隔断条。本申请通过将第一侧部花纹块和第二侧部花纹块错位设置,能够在同一时间使两者撞击地面时产生不同的声压幅值,避免第一侧部花纹块和第二侧部花纹块撞击地面时产生声能叠加。同时,在轮胎胎面的纵向沟槽中设置隔断条,能够将连续的纵向沟槽进行隔断,并阻断空气在纵向沟槽中的连续流动,从而降低空气在胎面纵向沟槽中高速流动时产生的噪音。
