内容記述(抄録等)
Cornering force is useful to keep the travelling of tractor along the contour line on the side slope field. It is produced by rolling a tire at a slip angle, so that the plane of the tire is at an angle to its direction of motion, but the tire deflects laterally under the influence of the cornering force.
This paper deals with the influences of inflation pressure for cornering force, running resistance, and deflection of tire. Test device used in this experiment is two wheel cart using smooth tire, 450 mm across and 113 mm wide.
The test results are as follows :
1. High inflation pressure makes increase the cornering force at the small slip angle, because of relatively low rolling resistance.
2. The lateral deflection of tire is large on the furrow wheel, nevertheless it can be neglected on the land wheel. It is due to the weight transfer by the axial force on the wheel axle.
3. The using of permissively high inflation pressure for the furrow wheel, therefore, is recommended for the purpose of decreasing deflection.
