[0051] definition

[0052] For the purposes of this specification, the following terms are defined as follows.

[0053] "Equatorial plane" means the plane perpendicular to the axis of rotation of the tire passing through the centerline of the tire.

[0054] "Meridian" means a plane parallel to the axis of rotation of the tire and extending radially outward from said axis.

[0055] "Hysteresis" denotes the dynamic loss tangent measured at 10% dynamic shear strain and 25°C.

[0056] figure 1 A non-pneumatic tire 100 of the present invention is shown. The tire of the present invention comprises a radially outward ground engaging tread 200 , a shear band 300 and a spoke disk 400 . The non-pneumatic tire of the present invention is designed as a top load construction such that the shear strap 300 and attached spoke disk 400 efficiently carry the load. The shear band 300 and attached spoke disk 400 are designed such that the stiffness of the shear band is directly related to th...

Abstract

The invention relates to a non-pneumatic tire. A structurally supported tire includes a ground contacting annular tread portion; a shear band, and a connected spoke disk connected to the shear band. The connected spoke disk has two or more circumferential spokes joined together by a connecting web, wherein the spring rate of the connected spoke disk is greater than the spring rate of the shear band.

Description

technical field [0001] The present invention relates generally to vehicle tires and non-pneumatic tires, and more particularly, to non-pneumatic tires. Background technique [0002] Pneumatic tires have been the solution of choice for vehicle mobility for over a century. Pneumatic tires are tension structures. Pneumatic tires have at least four characteristics that make pneumatic tires so advantageous today. Pneumatic tires carry loads efficiently because all tire structure participates in carrying the load. Pneumatic tires are also desirable because they have low contact pressure, thus reducing wear on the road due to the distribution of the vehicle load. Pneumatic tires also have low stiffness, which ensures a comfortable ride. The main disadvantage of a pneumatic tire is that it requires compressed fluid. Conventional pneumatic tires are useless after a complete loss of inflation pressure. [0003] Tires designed to operate without inflation pressure eliminate many ...
