专利汇可以提供Tire tread pattern专利检索,专利查询,专利分析的服务。并且PURPOSE:To reduce pattern noises by changing the direction ngle of lug grooves in block patterns in response to a change of pitch lengths of the pattern in a tire provided with multiple block pattern carved in the peripheral direction on the tire tread. CONSTITUTION:I a tire provided with block patterns 1-3 continuously and repeatedly in the direction E-E' on the tire tread, lug grooves 4-6, 4'-6' in individual patterns 1-3 are extended in the tire grounding width direction D-D', and angles alphaA-alphaC', alphaA'-alphaC' with the grounding width direction are changed in response to pitch length A-C of individual patterns 1-3. For example, if A=48mm., B=41mm., C=36mm., W(groove width)=6mm.; alphaA=39.5 deg., alphaB=34.5 deg., alphaC= 30.5 deg., alphaA'=40 deg., alphaB'=35.0 deg., alphaC'=31.0 deg.. Accordingly, pattern noises generated during the car travel can be remarkably reduced.,下面是Tire tread pattern专利的具体信息内容。
