| Zusammenfassung: | PROBLEM TO BE SOLVED: To measure the rotational angle and the displacement of a tire by simple configurations.SOLUTION: A rotor part 22 of a rotation measurement unit is fixed to a wheel 4 of a tire and the rotation of the rotor part 22 to a stator part 21 of the rotation measurement unit is measured. A wire 13 of two wire-type linear encoder unit fixed to a vehicle body is connected to the stator part 21 of the rotation measurement unit, the rotation of the stator part 21 is prevented by the tensile force of the wire 13, and the displacement of the center axis of the tire is measured by the length for which the wire 13 is drawn.SELECTED DRAWING: Figure 5
【課題】簡易な構成によってタイヤの回転角と変位を計測する。【解決手段】回転測定ユニットのロータ部２２をタイヤのホイール４に固定し、回転測定ユニットのステータ部２１に対するロータ部２２の回転を計測する。車体に固定した二つのワイヤ式リニアエンコーダユニットのワイヤ１３を回転測定ユニットのステータ部２１に連結し、ワイヤ１３の張力によりステータ部２１の回転を抑止しつつ、ワイヤ１３の引き出し長さに基づいてタイヤの中心軸の変位を計測する。【選択図】図５ |
