    • A method capable of estimating a snowy road surface condition during vehicular travel in finer classification. In this method, tire vibrations in the circumferential direction, road surface temperature (T), and tire-generated sound are detected by an acceleration sensor, a road surface thermometer, and a microphone, respectively. Then band values P11, P12 and P13 for a pre-leading-edge region (R1), band values P21, P22 and P23 for a leading-edge region (R2), band values P31, P32 and P33 for a pre-trailing-edge region (R3), band values P41 and P42 for a trailing-edge region (R4), and band values P51, P52 and P53 for a post-trailing-edge region (R5) are calculated from the tire vibration data. A sound pressure level ratio (Q)=(PA/PB), which is the ratio of a band power value (PA) of a low frequency band to a band power value (PB) of a high frequency band, is calculated from data on the tire-generated sound. And a road surface condition is estimated, using the band values (Pij), road surface temperature data (T), sound pressure level ratio (Q), and wheel speed data.

    • A purpose of the present invention is to provide a rim wheel and a tire rim assembly which are capable of effectively reducing cavity resonance of a tire, and accordingly, enhancing quietness and riding comfort. A plurality of cap members 20 is arranged on an outer circumferential surface of a rim 16 in a circumferential direction thereof, diaphragms are disposed inwardly of each cap member 20, and a plurality of sub-air chambers 32 is formed between the rim 16 and the cap members 20 in a rim circumferential direction. The tire main air chamber 18 is connected to the sub-air chambers 32 through communicating holes 24 formed on the cap members 20. The sub-air chambers 32 and the communicating holes 24 constitute a Helmholtz resonance noise absorber that can absorb vibration with specified frequencies. Further, since the sub-air chamber 32 is not formed in a continuous annular shape in a tire circumferential direction, occurrence of cavity resonance can be suppressed and a substantial reduction in noise can be secured.
    • 本发明的目的是提供一种能够有效地减少轮胎的腔共振的轮辋轮和轮辋组件,从而提高安静性和乘坐舒适性。 在边缘16的圆周方向的外圆周表面上设置有多个盖构件20,隔膜设置在每个盖构件20的内侧,多个副空气室32形成在边缘16和 盖构件20在边缘周向方向上。 轮胎主空气室18通过形成在盖构件20上的连通孔24连接到副空气室32。 副气室32和连通孔24构成能够以特定频率吸收振动的亥姆霍兹共振噪声吸收体。 此外,由于副气室32在轮胎周向上不形成连续的环状,因此能够抑制空腔谐振的发生,能够确保噪音的显着降低。
