Title:
NON-PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2015/198637
Kind Code:
A1
Abstract:
The present invention provides a non-pneumatic tire (1) comprising: an attachment body attached to an axle; a ring-shaped body (13) that surrounds the attachment body from the outside in the tire radial direction; a linking member (15) that links the attachment body and the ring-shaped member so as to be freely displaceable; and a cylindrical tread member (16) mounted to the exterior of the ring-shaped body. The outer peripheral surface of the tread member is formed by a plurality of curved surface sections (41-43) that are continuous in the tire width direction (H) without level differences therebetween and is formed so as to project outward in the tire radial direction as seen in a cross-sectional view along the tire width direction. The plurality of curved surface sections have radii of curvature that mutually differ when seen in a cross-sectional view along the tire width direction. Among the plurality of curved surface sections, an intermediate curved surface section (42) located between a central curved surface section (41) located in the central section in the tire width direction and a shoulder curved surface section (43) located in the outer side in the tire width direction has a radius of curvature (R2) in the cross-sectional view that is greater than the radii of curvature (R1, R3) of the other curved surface sections.
