20120318417 | STRUCTURALLY SUPPORTED, NON-PNEUMATIC WHEEL WITH CONTINUOUS LOOP REINFORCEMENT ASSEMBLY - A non-pneumatic wheel is provided having a continuous loop reinforcement assembly that can support a load and have performance similar to pneumatic tires. Various configurations of a non-pneumatic wheel, including variations of the continuous loop reinforcement assembly, are provided. One or more resilient spacers can be positioned with the continuous loop reinforcement assembly and can be configured for the receipt of a matrix material. | 12-20-2012 |
20130069273 | METHOD AND APPARATUS FOR INSERTING A SPACER BETWEEN ANNULAR REINFORCEMENT BANDS - A method is provided for making an annular reinforcement structure having inner and outer reinforcement bands maintained in concentric alignment by a resilient spacing element positioned between the bands. The method includes the steps of placing the spacing element against the inside face of the outer reinforcement band and compressing the spacing element with a jig, adjacent the top edge of the outer reinforcement band. The spacing element is sufficiently compressed to allow the inner reinforcement band to slide into concentric alignment with the outer reinforcement band, with a minimum of deflection and/or distortion of the inner reinforcement band. | 03-21-2013 |
20130071582 | ANNULAR STRUCTURE HAVING MULTIPLE REINFORCEMENT BANDS - An annular reinforcement structure is provided having a first reinforcement band and a second reinforcement band in a spaced-apart, concentric relationship, and a cast-in-place core material positioned between the first and second reinforcement bands and bonded thereto. | 03-21-2013 |
20130071644 | ANNULAR REINFORCEMENT STRUCTURE - An annular reinforcement structure is provided having an inner reinforcement band, an outer reinforcement band positioned around and concentric with the inner reinforcement band, and a cast-in-place polymer foam spacer, which maintains the spatial orientation of the inner and outer reinforcement bands. The annular reinforcement structure may be embedded in an elastomeric matrix material to provide stability, such as for belt for power transmission. | 03-21-2013 |
20130240097 | SPOKE EDGE GEOMETRY FOR A NON-PNEUMATIC TIRE - The present invention provides improved spoke edge geometry for a non-pneumatic or hybrid tire that is less prone to fatigue when used. The present invention also provides a way to manufacture such geometry in a mold, In particular the spoke edge geometry is provided with a reduced cross-section that reduces the bending stresses locally and allows a unique mold construction that changes the placement and orientation of potential flash and reduces other potential molding flaws when a liquid such as polyurethane is introduced into the cavity of the mold to form a spoke. This change results in a reduction in the possibility of a stress riser being found near the edge of the spoke, enhancing the durability of the tire. | 09-19-2013 |
20130278044 | NON-PNEUMATIC TIRE WITH REINFORCEMENT BAND SPACER AND METHOD OF MANUFACTURING SAME - A non-pneumatic tire and a method of manufacturing the same are provided. More particularly, a non-pneumatic tire having a reinforcement structure with one or more spacers is provided along with a method of placement of a spacer between reinforcing bands of a non-pneumatic tire. A jig can be used to facilitate placement of the spacer. | 10-24-2013 |
20130278045 | ANNULAR STRUCTURE HAVING MULTIPLE REINFORCEMENT BANDS - A non-pneumatic wheel with reinforcement bands that provide structural support for the wheel and a method of manufacture of such a wheel are described. The reinforcement band forms part of an annular reinforcement structure that includes a core that is cast in place between annular reinforcement bands. The core can be impregnated with a matrix material. The matrix material can also be used to form one or more elements of the non-pneumatic wheel. | 10-24-2013 |
20130284329 | STRUCTURALLY SUPPORTED NON-PNEUMATIC WHEEL WITH REINFORCEMENTS AND METHOD OF MANUFACTURE - A non-pneumatic wheel with reinforcement bands that provide structural support for the wheel and a method of manufacture of such a wheel are described. The reinforcement band forms part of an annular reinforcement structure that includes foam spacers positioned between the annular reinforcement band. The foam can be a reticulated foam into which a matrix material such as a polyurethane is introduced. The matrix material can also be used to form one or more features of the non-pneumatic wheel such as spokes, a mounting band, and a hub. | 10-31-2013 |
20130287982 | POLYURETHANE - A polyurethane that is a reaction product of reaction components, the reaction components comprising (a) a polyol; (b) a polyisocyanate selected from an aromatic, alicyclic or aliphatic polyisocyanate or combinations thereof; (c) a mixture of chain extenders that includes (i) a chain extender having a sulfur bridge in an amount of between 1 and 30 weight percent of the total mixture of claim extenders and (ii) a main chain extender, wherein the chain extender having a sulfur bridge. The chain extender having a sulfur bridge may be characterized as | 10-31-2013 |
