Detailed description of the invention
Embodiment of the present utility model is explained below in conjunction with accompanying drawing:
As shown in Figure 2, the utility model discloses a kind of cross-country car air tread pattern structure, tire protector is made up of several decorative pattern unit 20 along the distribution of tire circumference, each decorative pattern unit 20 comprises the center running lug 21 that is arranged on tyre surface center, two symmetries are positioned at the first middle pattern block 22 of center running lug 21 both sides, lay respectively at the first middle pattern block 22 front and back and with tyre surface Central Symmetry arrange the second middle pattern block 23 and be symmetrical in tyre surface center and and in the pattern block on tire shoulder 24 of tire shoulder position, wherein tyre surface center running lug 21 and the second middle pattern block 23 rectangular-shaped for growing crosswise, first middle pattern block 22 and pattern block on tire shoulder 24 are that lengthwise is rectangular-shaped, tyre surface center running lug 21 and the first middle pattern block 22 design side by side, second middle pattern block 23 is arranged in axially spaced-apart with center running lug 21 and the first middle pattern block 22, pattern block on tire shoulder 24 and the first middle pattern block 22 and the second middle pattern block 23 are arranged in circumferential interval, so guarantee the tractive property of hard place shape road traveling,
Key of the present utility model is: the circumferential edge of center running lug 21 and the first middle pattern block 22 is that concavo-convex drop is arranged, and the peripheral level of the first middle pattern block 22 is higher than the peripheral level of center running lug 21; One group of second middle pattern block 23 being positioned at center running lug 21 rear is inclined to set with axial, is positioned at one group of second middle pattern block 23 in center running lug 21 front with one group of second middle pattern block 23 at center running lug 21 rear in being axially symmetrical arranged simultaneously.
Between described center running lug 21 and the first middle pattern block 22, height difference H 1 is 0.5mm ~ 5mm, and make the axial edge of each pattern block be the convex settings in middle concave both sides, before and after pattern block like this, side is symmetrical arranged, and can increase axial earth approach, promotes tractive property.
And the second middle pattern block 23 being positioned at center running lug 21 rear is set to 5 ° ~ 20 ° with axioversion angle [alpha], make the edge ratio of this second middle pattern block 23 near axial inner side low near the edge axially; The second middle pattern block 23 being then symmetrical in center running lug 21 front is higher than the edge near axial outside near the edge of axial inner side, therefore before and after pattern block, side is symmetrical arranged, utilize the concavo-convex drop design of the axis of pattern block, increase axial earth approach, improve pattern block axial edge composition, promote axial traction performance during hag shape road traveling.
Another is promote each pattern block cuts earth ability when hag shape road traveling further, by center running lug 21, first middle pattern block 22, in the axial direction of the second middle pattern block 23 and pattern block on tire shoulder 24, outer ledge all adopts concavo-convex drop to arrange, make center running lug 21, first middle pattern block 22, the circumference of the second middle pattern block 23 and pattern block on tire shoulder 24 is the convex setting in recessed centre, both sides, center running lug 21, first middle pattern block 22, the axial height of concave convex difference H2 of the second middle pattern block 23 and pattern block on tire shoulder 24 is set to 0.5mm ~ 5mm, pattern block circumferential edge composition can be increased, improve circumferential earth approach, improve circumferential tractive property during hag shape road traveling.
Whole installation like this, can guarantee the tractive property of tire hard place shape road traveling, improves the tractive property of hag shape road traveling.
The above, it is only the utility model embodiment, not technical scope of the present utility model is imposed any restrictions, therefore every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
