    • PROBLEM TO BE SOLVED: To provide an agricultural wheel capable of providing sufficient traction even if traveling on a muddy land.
      SOLUTION: The agricultural wheel 1 is designated in a rotating direction R, and includes a wheel body 6 and a plurality of lugs 12 having projecting ends being ground contact surfaces 15. The lugs include a pair of auxiliary blades 16 projecting to both sides in the width direction at a rotating direction side. The auxiliary blades include tread surfaces 18 directed to the rotating direction side and inclined in the radial direction so that the inside of the radial direction may be located at the rotating direction side. When a distance between mutual width direction outer ends in the auxiliary blades is Sa, a width direction dimension and a peripheral direction dimension of each of the ground contact surfaces are Sb and Sd, respectively, the thickness of each of the projecting ends is Sc, and the inclination of a crossing line Li between a virtual plane MG1 passing a width direction end of the wheel body 6 and orthogonal to the rotation center and the tread surface to a virtual plane MG3 passing a root Rb to the wheel body at the width direction end of the tread surface and the rotation center is θ(degree), expressions of 1.5Sb≤Sa≤2.0Sb, 0.2Sd≤Sc≤0.4Sd and 20≤θ≤50 are satisfied.

    • PROBLEM TO BE SOLVED: To provide a wheel for agricultural use in which the use of rubber is not considerably increased when the size thereof is increased, and less mud is deposited when a vehicle travels on a muddy ground. SOLUTION: The wheel for agricultural use with its rotational direction R during the normal use being designated has an elastic wheel body 3 which is provided with a substantially annular body part 18 and blade plates 16 projected on both sides in the axle direction from the body part and formed of an elastic material. The blade plates are inclined so that inner ends 17 in the radial direction are located on the rotational direction side from its outer ends 20 in the radial direction, and curved in a recessed shape with respect to the rotational direction while the degree of inclination to the rotational direction side is increased toward the outer end in the axle direction from the body part. The ratio (L-r)/r in the relationship of the distance L between the outer ends on both sides in the axle direction in the blade plates to and the width r in the axle direction of the body part is ≥6, and the angle θ formed by the line connecting the circumferential intermediate point P2 at a roof of the body part in the blade plates to a circumferential intermediate point P1 on the outer end in the axial direction and the circumferential direction is ≥75° and ≤86°.

    • PROBLEM TO BE SOLVED: To transmit information, pressure and air by making a spoke and rim hollow and to maintain strength of the spoke and rim when parts such as a sensor and and a hydraulic system are attached to a tire and the information of air pressure of the tire is obtained although the spoke and the rim usually have no cavity in view of strength.
      SOLUTION: The rim and the spoke possesses a characteristic capable of transmitting information, air and oil by providing cavity on the spoke and rim of a wheel. Transmitting the information, air and hydraulic pressure is useful for not only the spoke and rim but also the tire installed with respective sensors or equipment.

    • 要解决的问题:通过使轮辐和轮辋中空的方式传递信息,压力和空气,并且当诸如传感器和液压系统的部件附接到轮胎和信息时保持辐条和轮辋的强度 获得轮胎的空气压力,尽管轮辐和轮辋通常在强度方面没有空腔。

      解决方案:轮辋和轮辐具有能够通过在车轮的轮辐和轮辋上提供空腔来传递信息,空气和油的特性。 传输信息,空气和液压压力不仅可用于辐条和轮辋,而且也适用于安装有相应传感器或设备的轮胎。 版权所有(C)2005,JPO&NCIPI
