The present invention provides a tire tangential direction load measuring device capable of directly measuring a tangential direction load on a tire without using a bulky device, and a tire rolling resistance evaluating device capable of evaluating the rolling resistance of a tire using the tire tangential direction load measuring device. A tire tangential direction load measuring device (10) is provided with: at least two loading rollers (44A, 44B) which have a smaller diameter than a tire and which are arranged side-by-side; an air cylinder (13) serving as a movement mechanism capable of pressing the at least two loading rollers (44A, 44B) with a prescribed applied load fz against the rolling tire; and a strain gauge (51) serving as a tangential direction load sensor for measuring a tangential direction load fx on the rolling tire when surfaces of the at least two loading rollers (44A, 44B) are pressed against a tread surface of the tire with the prescribed applied load fz. Further,the tire rolling resistance evaluating device employs the tangential direction load measuring device (10).
提供能够不使用大型的装置而直接计测轮胎的切线方向载荷的轮胎的切线方向载荷计测装置及能够使用该轮胎的切线方向载荷计测装置进行轮胎的滚动阻力评价的轮胎的滚动阻力评价装置。轮胎的切线方向载荷计测装置(10)具备:两根以上的负荷辊(44A、44B),直径比轮胎小,并且被排列配置;作为移动机构的气缸(13),能够将该两根以上的负荷辊(44A、44B)以规定的负荷载荷fz推压到旋转的轮胎;以及作为切线方向载荷传感器的应变仪(51),两根以上的负荷辊(44A、44B)的表面被以前述规定的负荷载荷fz推压到轮胎的胎面,用来计测旋转的状态的轮胎的切线方向载荷fx。此外,轮胎的滚动阻力评价装置使用该切线方向载荷计测装置(10)。
