摘要： It is provided a pneumatic tyre, the tyre having a circumferential direction, an axial direction and an equatorial plane, and the tyre comprising: a tread extending in a tyre circumferential direction, said tread comprising at least one circumferential groove running continuously in the circumferential direction, and a plurality of axial grooves or transverse grooves running at an angle to the axial direction, and a plurality of blocks defined by the circumferential groove and the axial grooves or transverse grooves, said blocks extending radially between an inner surface of the tread and a tread surface to come into contact with the ground, wherein at least some of the blocks comprise at least one wavy groove that extends from a circumferential groove inwardly into the block, and wherein the wavy groove has a depth extending radially from the tread surface to come into contact with the ground towards the inner surface that ends above the inner surface (26) of the tread.

摘要： It is provided a pneumatic tyre having an equatorial plane for an agricultural machine, comprising: a tread having a first and a second lateral tread edge, the axial distance between the first and second lateral tread edges being the width of the tread, wherein the tread comprises a plurality of lugs extending radially between an inner surface of the tread and a tread surface to come into contact with the ground; and first lugs extending from the first lateral tread edge toward the inner equatorial plane, having a shoulder portion extending from the first lateral tread edge and a nose portion at the inner equatorial plane, and each of the first lugs having: an arcuate leading edge that arcs from the first lateral tread edge to an axial leading nose edge next to a substantially circumferential inner nose edge, and an arcuate trailing edge that arcs from the first lateral tread edge to the substantially circumferential inner nose edge; and second lugs extending from the second lateral tread edge toward the inner equatorial plane, having a shoulder portion extending from the second lateral tread edge and a nose portion at the inner equatorial plane, and each of the second lugs having: an arcuate leading edge that arcs from the second lateral tread edge to an axial leading nose edge next to a substantially circumferential inner nose edge, and an arcuate trailing edge that arcs from the second lateral tread edge to the substantially circumferential inner nose edge, wherein for each lug the length of the substantially circumferential inner nose edge is longer than the length of the axial inner nose edge and the width of said lug increases from the corresponding shoulder portion to the nose portion of said lug.

摘要： It is provided a pneumatic tyre (1) comprising: an inner surface (2), a tread portion (3), a pair of sidewall portions (4) radially inwardly extending from both edges of the tread portion (3), and bead portions (5) disposed at radially inner edges of the sidewall portions (4), and a sound absorbing device (6) made of a spongy material which is adhered to the inner surface (2) of the pneumatic tyre (1) at a tread region and extends in the tyre circumferential direction, wherein the sound absorbing device (6) comprises at least first and second sound absorbing members (7), wherein the at least first and second sound absorbing members (7) are separated from each other by a distance (S) in the axial tyre direction and are adhered to the inner surface (2) of the pneumatic tyre (1) by an adhesive component (8), wherein the adhesive component (8) comprises at least two annular- shaped adhesive beads (9) provided between each first and second sound absorbing member (7) and the inner surface (2) of the tyre (1), wherein the at least two adhesive beads (9) are arranged spaced apart from each other in the axial direction and extend in the circumferential direction of the tyre (1).

摘要： The present invention relates to a cross-linkable rubber composition, a cross-linked rubber composition obtained by cross-linking such a rubber composition, a method of preparing a tyre and a tyre. In a cross-linkable rubber composition the cross-linkable rubber composition comprises, per hundred parts by weight of rubber (phr): ≥1 phr to ≤99 phr of a rubber component selected from the group of styrene-butadiene rubber (SBR), polybutadiene rubber (BR), natural rubber (NR) or a mixture thereof; and ≥1 phr to ≤120 phr of an aliphatic resin component. The composition further comprises ≥1 phr to ≤50 phr of a polyisoprene rubber (IR) having ≥mol-%, as determined by NMR spectroscopy, of 3,4-linked units derived from isoprene. It has surprisingly been found that such a polyisoprene rubber having 3,4-linked units derived from isoprene in combination with aliphatic resin worked very well in broadening the tan delta curve of the compound, indicating the compound can perform well in wide range of conditions when cured and used as a rubber for a tyre tread.
