Detailed description of the invention
Explain embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model has disclosed a kind of cross-country road all-terrain vehicle air tread decorative pattern, this tire protector 1 comprise be positioned at tyre surface center along the symmetrical spaced core piece group 10 of tire axial, be positioned at the secondary pattern block group 20 at core piece group 10 circumferential intervals and be positioned at the shoulder pattern block group 30 of core piece group 10 left and right sides; Core piece group 10 comprises multiple center main pattern block 11 and multiple interval pattern blocks 12 between center main pattern block 11 that are circumferentially the arrangement of " S " font along tire; Secondary pattern block group 20 comprises the secondary pattern block 21 of " V " font and the multiple transition pattern block 22 between center main pattern block 11, and " V " font opening is towards tire axial outside, the secondary pattern block 21 of " V " font is across tyre surface center, and transition pattern block 22 is positioned at the secondary pattern block of " V " font 21 outsides; Certainly, secondary pattern block group 20 can be only for single secondary transition pattern block 23 be arranged on the circumferential interval of center main pattern block group 10; The shoulder pattern block group 30 of the left and right sides comprises multiple along the circumferentially sub-pattern block 31 of spaced left shoulder and the sub-pattern block 32 of right shoulder of tire, and the sub-pattern block 31 of each left shoulder and the sub-pattern block 32 of right shoulder are symmetrical arranged along tire axial separately from each other.
As shown in Figure 2, core piece group 10 is positioned at tyre surface center, and each core piece 11 is divided into LC pattern block 111 and right core piece 112 by tyre surface center ditch 13.LC pattern block 111 and right core piece 112 are symmetrical arranged along tire axial and tire centre plane separately from each other, and so setting can provide the balanced traveling comfort of the left and right sides in tire running process.For promoting the stability of tire straight-line travelling, guarantee the traveling comfort of tire running, the distance B between LC pattern block 111 axial outer end and right core piece 112 axial outer end can be set to 30%～60% of tread contour overall width TW.For further increasing the traveling comfort of tire running, can adopt respectively in the axial outer end of LC pattern block 111 and right core piece 112 the head setting of extension, the head extension width A of LC pattern block 111, right core piece 112 is 1.1 ~ 1.5 with the ratio of the body width B of LC pattern block 111, right core piece 112 respectively.The head angle α of LC pattern block 111, right core piece 112 is 120 °～150 ° simultaneously, the ride comfort so can increase tire running ground connection time, thus improve the traveling comfort travelling.In addition; LC pattern block 111, right core piece 112 are 10 °～30 ° with the angle β of tire axial; axially angle β arranges when excessive enough axial edge effects cannot be provided; will greatly reduce the tractive property of tire at cross-country road; axially angle β arranges when too small and cannot guarantee the continuity of pattern block ground connection, easily produces jumping phenomena and affect its comfort property in tire running process.For increasing the traveling comfort of tire running, circumferentially adjacent center main pattern block 11 can be arranged to or non-symmetrical form symmetrical along tire axial, in the time adopting symmetrical form, the interval pattern block 12 between center main pattern block 11 can adopt along circumferentially symmetrically arranged the first interval pattern block 121 of tire; In the time adopting non-symmetrical form, interval pattern block 12 between center main pattern block 11 can adopt the second interval pattern block 122 that is arranged at tyre surface center, in the time of tire running, setting like this can be guaranteed the continuity of ground connection between core piece 11, and avoiding affects its driving comfort because of discontinuous the produced jumping phenomena of ground connection.The present embodiment adopts the form of both combinations.
As shown in Figure 1, Figure 3, secondary pattern block group 20 comprises the secondary pattern block 21 of " V " font and the multiple transition pattern block 22 that are positioned at center main pattern block group 10 circumferential intervals, and " V " font opening is towards tire axial outside, and transition pattern block 22 is positioned at V " the open end outside of the secondary pattern block 21 of font.The transition pattern block 22 of the present embodiment is two, is respectively First Transition pattern block 221 and the second transition pattern block 222.For the homogeneity that improves tire ground connection is to guarantee driving comfort, one end pin of secondary pattern block 21 open ends of " V " font adopts to the extension head 211 bending in opening and designs.For avoiding the rigidity of the secondary pattern block 21 of " V " font excessive, can a groove 212 be set in the middle part of the secondary pattern block 21 of " V " font.The angle γ of the secondary pattern block 21 of " V " type is 60 °～110 °.Cannot provide enough spoil disposal spaces when angle γ arranges when too small, affect its tractive property; Otherwise when angle γ arranges the resistance that will strengthen the secondary pattern block of " V " font 21 incision ground, end when excessive, cannot provide good tractive property.First Transition pattern block 221 and the second transition pattern block 222 can be symmetrical or asymmetric setting along tire axial.First Transition pattern block 221 and the second transition pattern block 222 all adopt lalongate setting, and itself and tire axial are roughly in a parallel set, and can guarantee that shoulder has enough spoil disposal spaces and also can increase the axial edge effect of this pattern block simultaneously, guarantee its tractive property.Certainly, also can single secondary transition pattern block 23 be only set according to the axially-spaced locations size of practical center pattern block group 10, the present embodiment adopts secondary pattern block group 20 form total with single secondary transition pattern block 23.
As shown in Figure 4, shoulder pattern block group 30 is circumferentially spaced and forms by the sub-pattern block 31 of multiple left shoulders and the sub-pattern block 32 of right shoulder, the sub-pattern block 31 of left shoulder and the sub-pattern block 32 of right shoulder are symmetrical along tire centre plane and be staggered each other, and each circumferentially adjacent sub-pattern block 31 of left shoulder or the sub-pattern block 32 of right shoulder are each other along tire axial symmetry.When so setting can be guaranteed tire running, the ground connection conformability of the left and right sides, guarantees the equilibrium of traction property, also can promote the traveling comfort of tire running simultaneously.For further increasing the traction property of tire, can on the sub-pattern block 31 of left shoulder, groove 311 be set, on the sub-pattern block 32 of same right shoulder, groove 321 also can be set.
Adopt as Fig. 1 tire tread structural style to have manufactured experimently many front tyre specifications be 26X9.00R12, the rear tire specification all-terrain vehicle tire that is 26X11.00R12 and they are carried out to performance testing evaluation.To after each testing tire necessary rim 7.0 AT X12, inflation pressure 150kPa, be installed on all-terrain vehicle and travel on cross-country road, sense organ by chaufeur is evaluated respectively traction property, traveling comfort and overall performance, and traction property, traveling comfort and the overall performance of embodiment are all better than past case.
Can confirm to adopt after this tread design by test result, tire can be realized and when guaranteeing enough traction properties, improve the comfort property of tire in cross-country road driving process.
The above, be only the utility model preferred embodiment, do not limit with this scope that the utility model is implemented, and the equivalence of doing according to the technical solution of the utility model and description changes and modifies, and all should belong to the scope that the utility model is contained.
