Driving wheel of lorry tire tread decorative pattern, its technical scheme is for comprising groove, many circumferential pattern ditch even interval on the tyre surface at crown and tire shoulder position is offered, the circumferential pattern bar that crown center is the multipair left and right symmetry in boundary is take in formation, described each circumferential pattern bar is divided into some pattern blocks by the cross groove of circumference uniform distribution, described cross groove be axially the inclination at 0 °～5 ° of angles; From inside to outside, the width of described circumferential pattern bar increases gradually, and the cross groove on outermost circumferential pattern bar extends on the tyre surface at tire shoulder position, and in this cross groove, is provided with the reinforced rib that connects adjacent pattern block.
The reinforcing rib design of cros-rib tread bottom of trench has increased the rigidity of tire shoulder position tyre surface, can effectively avoid irregular wear.
In conventional design, article five, circumferential pattern ditch marks off 3 pairs of circumferential pattern bars, the outside circumferential pattern bar that is respectively inner side and middle two pairs of circumferential pattern bars and the tire shoulder position at crown position, the cross groove inclination angle of inner side circumferential pattern bar is contrary to the cross groove inclination angle of pattern rib with central longitudinal; The cross groove inclination angle of outside circumferential pattern bar is 0 ° and curved.Article five, circumferential pattern ditch along the circumferential direction, has reduced the rolling resistance of tire greatly, can also improve drainage and the heat-sinking capability of tire simultaneously.
The oblique alignment in pattern block position on the circumferential pattern bar of inner side; Pattern block location dislocation on left side or the adjacent circumferential pattern bar in right side.
For guaranteeing that tire can cut off moisture film at wet-skid road surface under steam, improve tire anti-slippery, in design, in central longitudinal, on the pattern block of pattern rib, offer and cross groove inclination angle Z-type groove in the same way; On the pattern block of outside circumferential pattern bar, offer and the arc groove of cross groove with radian.The design of fine groove can also be played heat radiation and effect attractive in appearance.
The cross groove length at tire shoulder position be on this circumferential pattern bar cross groove length 1/2～2/3.
On each circumferential pattern bar, pattern block is divided into 70～80.
On tyre surface, the degree of unsaturation of groove is 30%～35%.
Angle between the furrow bank of groove and tyre surface normal is 5 °～8 °, and angle is suitable, and tire has clean-up performance, is not easy inclusion.
Beneficial effect of the present invention:
