Non-pneumatic tire

摘要

A non-pneumatic tire includes an attachment body (11) attached to an axle, a ring member (14) including an inner rim (12) fitted onto the attachment body (11) and an outer rim (13) configured to surround the inner rim (12) from the outside in a tire radial direction, and a plurality of connecting members (15) disposed between the inner rim (12) and the outer rim (13) in a tire circumferential direction and configured to connect the rims (12) and (13) to each other, wherein at least a portion of the ring member (14) and the plurality of connecting members (15) are integrally formed of a synthetic resin material having a bending modulus of elasticity at −20° C. obtained through a 3-point bending test that is two times or less a bending modulus of elasticity at 60° C. obtained through the 3-point bending test pursuant to ISO 178.

1. A non-pneumatic tire comprising:
an attachment body attached to an axle; a ring member including an inner rim fitted onto the attachment body and an outer rim configured to surround the inner rim from the outside in a tire radial direction; and a plurality of connecting members disposed between the inner rim and the outer rim in a tire circumferential direction and configured to connect the rims to each other, wherein at least a portion of the ring member and the plurality of connecting members are integrally formed of a synthetic resin material having a bending modulus of elasticity at −20° C. obtained through a 3-point bending test that is two times or less a bending modulus of elasticity at 60° C. obtained through the 3-point bending test pursuant to ISO 178 (2010), wherein one end sections of the connecting members connected to the outer rim are disposed closer to the other side in the tire circumferential direction than the other end sections connected to the inner rim, wherein the connecting members comprise first elastic connecting plates and second elastic connecting plates configured to connect the rims to each other, and wherein the first elastic connecting plates and the second elastic connecting plates neighboring in the tire circumferential direction do not come in contact with each other.
