Definitions
- the present invention relates to a pneumatic tire and a pneumatic tire in which tire noise, particularly air column resonance at a frequency of approximately 800 to 1400Hz, is effectively reduced without substantially reducing wet performance of the tire.
- the present invention relates to a tread pattern design method.
- tire noise of approximately 800 to 1400 Hz is generated by air column resonance caused by resonance of an air column defined by a circumferential groove and a road surface in a tire contact surface.
- reducing the volume of the circumferential groove is effective for suppressing such columnar resonance.
- the purpose of this is not only to achieve a sufficient balance between steering stability and marginal grip characteristics on dry roads, but also to effectively suppress the deterioration of wet performance while maintaining the tire air column.
- two or more circumferential grooves that are continuous in a circumferential direction linear or zigzag are provided on the tread tread surface, and at least one circumferential groove has one end opened in the circumferential groove.
- the plurality of lateral grooves whose other ends terminate in the land portion are made independent of other peripheral grooves and other lateral grooves opening at the tread grounding edge, in other words, apart from the lateral grooves extending from the peripheral groove, other lateral grooves are provided. It is formed without intersecting with any of the other lateral grooves that can be opened in the peripheral groove and the other lateral grooves that can be opened in the tread ground contact edge.
- each lateral groove is arranged so that at least one of the lateral grooves is completely included in the ground plane, and the width of the lateral groove in the ground plane is 30% of the groove width of the peripheral groove.
- the extension length of each lateral groove portion is 40% or more of the extension length of the peripheral groove in the ground contact surface.
- the applicable rim refers to the rim specified in the following standard
- the maximum air pressure refers to the air pressure specified corresponding to the maximum load capacity in the following standard
- Load capacity refers to the maximum mass that can be applied to a tire according to the following standards.
- the standard is determined by an industrial standard effective in an area where the tire is manufactured or used. For example, in the United States “THE TIRE AND RIM ASSOCIAR ION INC. YEAR BOOK", in Europe, “The European Tire and Rim Technical Organization STANDARDS MANUAL” ".
- the tread tread here means that when the tire is mounted on the applicable rim, the tire is filled with the maximum air pressure and placed vertically on a flat plate, and a mass corresponding to the maximum load capacity is loaded thereon. It refers to the surface area of the tread rubber that comes into contact with the flat plate.
- the air column resonance sound is generated by vibrating an air column defined by a circumferential groove and a road surface in the ground contact surface based on vibration of each part of the tire when rolling. It is generated based on resonance vibration with a wavelength twice as long as the length of the column.
- the frequency f of the columnar resonance sound is V
- the sound speed is V
- the tread Length in other words, included
- Such air column resonance is communicated by a mutual force S of a plurality of circumferential grooves extending continuously in the tread circumferential direction and a lateral groove extending crossing the circumferential grooves in the tread pattern of the tire. In that case, only columnar resonance due to one particular frequency will occur.
- the width, depth and number of the circumferential grooves have a greater effect on the sound pressure level of the resonance sound than on the resonance frequency.
- the air column resonance frequency varies between approximately 800-1400 Hz according to the contact length of the tread tread surface. Therefore, in order to make the above sound absorption frequency close to these frequencies, It is necessary that the ratio of the extension length of the lateral groove included in the ground contact surface to the peripheral groove length be 40% or more, more preferably 40% or more and 90% or less.
- the groove wall of the lateral groove is required. It is necessary that they do not come into contact with each other in the ground plane, and that one or more lateral grooves that open in a predetermined circumferential groove are always completely included in the ground plane.
- the extension length of the lateral groove is limited to the length of the portion where the groove width is 30% or more of the groove width of the peripheral groove.
- the groove width is small when it comes into contact with the road surface, and the groove volume is small, so a sufficient sound absorbing effect cannot be obtained.
- a lateral groove whose one end is opened in a specific peripheral groove and the other end is terminated in the land portion, another lateral groove that is opened in another peripheral groove, and an opening in a tread contact edge are further provided. It is formed without intersecting other grooves and deviations of the lateral grooves, and by controlling the resonance frequency of that specific circumferential groove, the resonance frequencies of a plurality of circumferential grooves during tire rolling can be reduced. As a result, it is possible to reduce the peak level of noise and greatly promote the generation of white noise compared to the case where air column resonance is generated by only one specific frequency. it can.
- the formation of the lateral groove with respect to the specific peripheral groove of interest can be performed on only one side of the peripheral groove, or can be performed on both sides thereof. Even in the case of misalignment, the intended function can be sufficiently exhibited in the lateral groove opening in the circumferential groove.
- lateral grooves are provided on both sides of the circumferential groove, assuming that all lateral grooves have the same size, a greater sound absorbing effect can be obtained by increasing the number of lateral grooves in the tread surface than when only one side is provided.
- the reduction in compression and shear stiffness of the tread block due to the increase in the lateral grooves can be suppressed as compared with the case where the same number of grooves are provided on only one side, so that deterioration in stability and the like can be prevented.
- two or more specific circumferential grooves having opened lateral grooves can be provided on the tread tread surface, and this also makes it possible to reduce the resonance frequency with other circumferential grooves. By dispersing, the same operation and effect as described above can be obtained.
- a plurality of shoulder lateral grooves extending between a pair of other circumferential grooves located farthest from the tire equator line and the tread contact edge and opening to both of them.
- the resonance frequency of those circumferential grooves can be increased more than that of the specific circumferential groove described above, and therefore, the effect of dispersing the resonance frequency is further improved.
- the groove width of the shoulder lateral groove is set to be 13 mm in the ground contact surface. According to this, the dispersion of the resonance frequency at which the impact sound with the road surface due to the lateral groove is almost negligible is reduced. The effect of can be maximized.
- two or more circumferential grooves that are continuous in the circumferential direction are provided on the tread tread surface, and at least one circumferential groove has one end thereof.
- each of these lateral grooves and the peripheral groove is formed at the other end of the lateral groove.
- the selection of the groove width, the groove depth, and the number of grooves as required, under the selection of the lateral groove length It can effectively reduce the air column resonance in the circumferential groove.
