The invention discloses an off-the-road tire tread with a three-dimensional sipe pattern structure, which comprises a central pattern block I and a central pattern block II which are alternately arranged in the circumferential direction, and shoulder pattern blocks are respectively arranged on two sides of the central pattern block I and the central pattern block II; the first central pattern block is separated from the two adjacent second central pattern blocks through a first transverse three-dimensional sipe groove and a second transverse three-dimensional sipe groove respectively, the first central pattern block and the second central pattern block are separated from the shoulder pattern blocks through longitudinal sipe grooves, and the adjacent shoulder pattern blocks are separated through main pattern grooves. The transverse three-dimensional sipe pattern grooves I, the transverse three-dimensional sipe pattern grooves II, the longitudinal sipe pattern grooves and the main pattern grooves are communicated with one another; and the groove walls of the transverse three-dimensional sipe grooves I and the transverse three-dimensional sipe grooves II are zigzag. The overall saturation degree of the tread pattern is 75-85%, the tread rigidity is high, and the tire has good puncture resistance and abrasion volume and is suitable for scenes with severe working conditions.
本发明公开了一种具有立体刀槽花纹结构的工程机械轮胎胎面,包括周向交替设置的中央花纹块一和中央花纹块二,中央花纹块一与中央花纹块二的两侧分别设置有肩部花纹块;中央花纹块一与相邻的两个中央花纹块二之间分别由横向立体刀槽花纹沟一和横向立体刀槽花纹沟二隔开,中央花纹块一和中央花纹块二与肩部花纹块之间由纵向刀槽花纹沟隔开,相邻的肩部花纹块之间由主花纹沟隔开,且横向立体刀槽花纹沟一、横向立体刀槽花纹沟二、纵向刀槽花纹沟和主花纹沟相连通;横向立体刀槽花纹沟一和横向立体刀槽花纹沟二的沟壁呈锯齿形。本发明的胎面花纹整体饱和度为75‑85%,胎面刚度高,具有良好的耐刺扎性和磨耗体积,适用于工况条件恶劣的场景。
