Abstract
A shear band that may be used e.g., in a non-pneumatic tire is provided. The shear band uses interlaced reinforcing elements positioned within a shear layer of elastomeric material. A variety of configurations may be used to create the interlaced positioning of the reinforcing elements including e.g., a horizontal diamond or vertical diamond configuration.
Claims20
An annular shear band defining axial, radial, and circumferential directions, the annular shear band comprising:
- an annular shear layer constructed from at least one elastomeric material, the annular shear layer having a width along the axial direction and having a thickness along the radial direction;
- and
- a plurality of discrete, annular reinforcing elements positioned along a plurality of axially-oriented rows throughout the annular shear layer, the reinforcing elements separated from one another by a predetermined distance, the reinforcing elements interlaced along the axial or radial direction of the shear band;
- wherein a volume fraction of the annular reinforcing elements in the annular shear layer is greater than a volume fraction of the at least one elastomeric material in the annular shear layer.

A non-pneumatic tire defining axial, radial, and circumferential directions, the non-pneumatic tire comprising:
- an annular shear band defining axial, radial, and circumferential directions, the annular shear band including
- an annular shear layer constructed from at least one elastomeric material, the annular shear layer having a width along the axial direction and having a thickness along the radial direction;
- a plurality of discrete, annular reinforcing elements surrounded by the at least one elastomeric material and positioned along a plurality of axially-oriented rows throughout the annular shear layer;
- the reinforcing elements separated from one another by a predetermined distance;
- the reinforcing elements interlaced along the axial or radial direction of the shear band;
- wherein a volume fraction of the annular reinforcing elements in the annular shear layer is greater than a volume fraction of the at least one elastomeric material in the annular shear layer;
- a plurality of tension-transmitting web spokes extending along the axial direction and radially inward from the annular shear band;
- and
- a mounting band positioned at a radially-inner end of the web spokes.
