Claim 0:
1. An annular shear band defining axial, radial and circumferential directions, the annular shear band comprising:
an annular shear layer constructed from a rubber composition;
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, each reinforcing element having a centerpoint, wherein the reinforcing elements are interlaced along the axial or radial direction of the shear band such that the centerpoints of reinforcing elements of adjacent, axially-oriented rows are arranged to form a rhombus having non-orthogonal angles between sides of the rhombus, wherein the rubber composition is based upon a cross-linkable rubber composition, the cross-linkable rubber composition comprising, in parts by weight per 100 parts by weight of rubber (phr):
between 50 phr and 100 phr of a natural rubber;
between 0 phr and 50 phr of a second rubber component selected from the group consisting of polybutadiene rubber, a copolymer of polybutadiene and styrene wherein the copolymer has no more than 5 mol % styrene and combinations thereof;
between 15 phr and 40 phr of a reinforcing filler that comprises at least 5 phr but no more than 35 phr of a total amount of a carbon black, the total amount of the carbon black limited to a first portion having a target surface area of between 25 m2/g and 39 m2/g and between 0 phr and 5 phr of a second portion having its surface area of other than between 25 m2/g and 39 m2/g; and
a sulfur cure system.
