A traction band substantially made from elastomeric material is disclosed. The traction band comprises a main band body divided into a plurality of sections connected together along laterally extending pitch lines. The band body has an interior wheel-engaging surface, adapted to cooperate with the various wheels of a track system, and an exterior ground-engaging surface adapted to engage the ground. The wheel-engaging surface comprises one or more rows of longitudinally spaced-apart drive lugs and/or guide lugs typically disposed on each of the band sections. The ground-engaging surface comprises traction lugs extending longitudinally across more than one band section, these traction lugs comprising laterally extending bending regions where the traction lugs are thinner. These bending regions are substantially aligned with regions on the interior surface which are devoid of drive lugs and guide lugs.
1) A traction band comprising a band body divided into a plurality of sections attached together along laterally extending pitch lines, said body having an inner wheel-engaging surface and an outer ground-engaging surface, said inner surface comprising drive and/or guide lugs wherein consecutive drive and/or guide lugs are separated by regions extending along said pitch line and devoid of said drive and/or guide lugs, said outer surface comprising traction lugs, wherein at least one of said traction lugs extends longitudinally across more than one of said sections, said at least one traction lug comprising at least one thinner region extending along one of said pitch lines.
15) A traction band comprising a band body divided into a plurality of band sections connected together along laterally extending pitch lines, said body having an inner surface and an outer surface, said inner surface comprising inner lugs disposed longitudinally on said band sections, consecutive inner lugs being separated by laterally extending regions substantially aligned with said pitch lines and devoid of said inner lugs, said outer surface comprising outer lugs, some of said outer lugs extending longitudinally across more than one of said band sections, said some of said outer lugs comprising thinner regions substantially aligned with said pitch lines.
20) A traction band comprising a band body divided along laterally extending pitch lines, said band body having an inner surface and an outer surface, said inner surface comprising one or more rows of longitudinally aligned and spaced-apart inner lugs, consecutive inner lugs being separated being lug-less regions substantially aligned with said pitch lines, said outer surface comprising outer lugs, some of said outer lugs comprising thinner regions substantially aligned with said pitch lines.
