Embodiment Construction

[0017] The present invention includes a method for molding spokes of a non-pneumatic tire and a method of forming a non-pneumatic tire wherein one or more spokes of a non-pneumatic tire are contained in a release agent applied to the spokes used to form the one or more spokes. Conductive material for the mold of the spokes. Conductive material may be disposed along an outer (ie, exterior) surface of each such spoke and / or embedded within the thickness of each such one or more spokes. Disposing the conductive material within the thickness of the spokes is beneficial because conductive material disposed on the outer surface tends to wear or wash away, or otherwise be more easily removed.

[0018] In particular embodiments, a non-pneumatic tire includes a tread for engaging a ground surface and a hub for operably attaching the tire to a land vehicle. A plurality of spokes extend in a radial direction between the tread and the hub, each spoke of the plurality of spokes forming an...

Abstract

Embodiments of the invention include a non-pneumatic tire (100) having electrically conductive paths and methods for forming the non-pneumatic tire. It should be understood that electrical charges may be generated during operation of a land vehicle, and that land vehicles are typically grounded by providing a conductive path between the vehicle and the ground. In an embodiment of the present invention, a non-pneumatic tire (100) and a method for forming a non-pneumatic tire to provide an electrically conductive path between a vehicle and the ground at the non-pneumatic tire are described. The method for forming the non-pneumatic tire includes the step of applying a release agent (290) to one or more molding surfaces (280) of a spoke mold, wherein the release agent (290) comprises a conductive additive.

Description

technical field [0001] This invention relates generally to non-pneumatic tires, and more particularly to spokes for molded non-pneumatic tires. Background technique [0002] An emerging field in tire development involves the manufacture and use of non-pneumatic or hybrid tires that do not rely solely on pressurized gas to structurally support the tire. Therefore, these non-pneumatic tires are less prone to flats that could render pneumatic tires inoperable. An exemplary non-pneumatic tire is described in US Patent No. 7,201,194 (also referred to herein as the '194 patent), the contents of which are incorporated herein by reference. [0003] In one example, a non-pneumatic tire comprises an outwardly extending tread attached to a plurality of spokes spaced about the tire's axis of rotation and each of the spokes extending radially from a hub at an inwardly extending Extended vertically. The spokes are operatively connected to each of the tread and the hub by any means know...
