Spoke for a tire with optimized thickness for improved durability |
| 摘要 |
The present invention provides spoke geometry for a non-pneumatic tire that is less prone to fatigue when used. In particular, the spoke geometry is provided with an optimized thickness profile over the length of the spoke. This optimization results in a reduction in the peak strain energy density levels in the spoke, thereby reducing the likelihood of crack initiation and propagation which in turn enhances the durability of the spoke and tire. |

1. A tire that defines radial and transverse directions and comprises a tread and a spoke having body geometry including a thickness that varies along the length of the spoke along the general radial direction that starts at one value, that gradually reduces to a second value, that then gradually increases to a third value, that then reduces to a fourth value and that then increases again to a fifth value wherein the length of said spoke follows a path and said path is offset from perfectly straight path from a first end of said spoke a second end of said spoke. |
