Title:
NON-PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2016/148295
Kind Code:
A1
Abstract:
This non-pneumatic tire (1) is provided with an attachment body (11) attached to an axle, a ring-shaped body (13) enclosing the attachment body (11) from the outer side with respect to the tire diameter direction, and linking members (15) for linking the attachment body (11) and the ring-shaped body (13) in a displaceable manner. A plurality of the linking members (15) are arranged along the tire circumference direction and are provided with elastic linking plates (21, 22) linked at both ends to the attachment body (11) and the ring-shaped body (13). The bending stiffness EI1 of the elastic linking plates (21, 22) as represented by the E1×W1×t13/12 is less than the bending stiffness EI2 of the ring-shaped body (13) as represented by the formula E2×W2×t23/12, where t1 (mm) is the average thickness in the tire circumference direction, W1 (mm) is the average width in the tire width direction H, E1 (MPa) is the Young's modulus, t2 (mm) is the average thickness in the tire radial direction, W2 (mm) is the average width in the tire width direction H, and E2 (MPa) is the Young's modulus.
