Abstract
A non-pneumatic tire for a vehicle featuring a body of elastic material and having a circumferentially-extending crown portion featuring a running surface and circumferentially-extending sidewalls joined to the crown portion. The side walls terminate in circumferentially-extending beads which are adapted to engage the rim of a vehicle wheel. A number of radially-extending and circumferentially-spaced compound-curve springs made of a composite material are at least partially embedded within the crown portion and the sidewalls. The curved springs have ends terminating within the beads of the tire body. A circumferentially-extending belt constructed of a high-strength and low stretch material is positioned radially outside of the compound-curve springs.
Claims14
A non-pneumatic tire for a vehicle comprising:
- a. a body made of an elastic material and having a circumferentially-extending crown portion featuring a running surface and circumferentially-extending first and second sidewalk joined to said crown portion, said circumferentially-extending first and second side walls terminating in circumferentially-extending first and second beads, respectively, said first and second beads adapted to be secured within a flange of a rim of a vehicle wheel;
- and
- b. a plurality of radially-extending and circumferential-spaced compound-curve springs at least partially embedded within said crown portion and said first and second sidewalls of the tire body, each of said compound-curve springs having a first end portion, the first end portion being embedded within the first bead of the tire body, a second end portion, the second end portion being embedded within the second bead of the tire body, a first sidewall that is generally S-shaped and a second sidewall that is generally inverted S-shaped;
- wherein the sidewalls of each spring each include upper and lower sidewall portions with the upper sidewall portions being convex with respect to a radial plane of the tire and the lower sidewall portions being concave with respect to the radial plane of the tire.
