Abstract
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.
