The specific embodiment
Below in conjunction with accompanying drawing, explain embodiment of the present utility model:
As shown in Figures 1 to 5, the utility model has disclosed a kind of middle hard pavement airtyred tread pattern structure of all-terrain vehicle, on this tire protector 1, be uniformly distributed circumferentially several decorative pattern unit, each decorative pattern unit comprises the two core pieces 10 that are positioned at tyre surface middle part and the shoulder pattern block 20 that lays respectively at tyre surface both sides; Core piece 10 is for being laterally generally the pattern block of V-shape, two core pieces 10 circumferentially and are axially symmetrical arranged successively and are alternately along tire each other and arrange, the V word opening of the two is towards tyre surface both sides, and two core pieces 10 circumferentially and are axially provided with and partly overlap along tire simultaneously; Tyre surface shoulder pattern block 20 is one to be laterally the pattern block of large V-shape, the shoulder pattern block 20 of tyre surface both sides circumferentially and is axially symmetrical arranged successively along tire, and V word opening is towards tyre surface center, the two ends pin of shoulder pattern block 20 V-shapes is main shoulder pattern block 21 and secondary shoulder pattern block 22, and main shoulder pattern block 21 is all set to reduce gradually after increasing gradually to tire shoulder place near tyre surface centre plane CL place with secondary shoulder pattern block 22 circumferential lengths again.
As shown in Figure 1, two core pieces 10 adopt the horizontal profile setting that is generally V-shape can increase the edge effect of pattern block, make core piece 10 more easily cut ground, promote the tractive property of tire.
In conjunction with shown in Fig. 1, Fig. 2, the maximum axial distance T1 of the axial outer end A of core piece 10 and tyre surface centre plane CL is set to 10% ~ 25% of tread contour width TW again, and this design can promote the comfort property of tire running.For reaching best comfort property, the maximum axial distance T1 of the axial outer end A of core piece 10 and tyre surface centre plane CL is preferably 12% ~ 20% of tread contour width TW.The edge, front and back of core piece 10 and the circumferential angle α of tyre surface centre plane CL are set to 50 ° ~ 85 ° simultaneously, are preferably 60 ° ~ 80 °.Arranging of this angle will effectively promote the tractive property of tire.For guaranteeing there is suitable appearance mud space to guarantee tractive property near tyre surface centre plane CL, tap drain furrow width T2 between two core pieces 10 of each decorative pattern unit is 10% ~ 25% of single decorative pattern unit circumferential lengths, is preferably 12% ~ 20% of single decorative pattern unit circumferential lengths.
As shown in Figure 3, for guaranteeing the traveling comfort of tire used, two core pieces 10 of each decorative pattern unit are circumferentially provided with and partly overlap along tire, and its circumferential overlap distance T3 is set to 3% ~ 25% of single decorative pattern unit circumferential lengths, are preferably 5% ~ 15% of single decorative pattern unit circumferential lengths.
As shown in Figure 4, ground connection traveling comfort and the tractive property of considering tire running promote, two core pieces 10 of each decorative pattern unit are arranged to be provided with and partly overlap along tire axial, and the axial overlap between core piece 10 is 3% ~ 20% of tread contour width TW apart from T4.
Again as shown in Figure 2, for avoiding core piece 10 to produce in the process of moving irregular wear, can on core piece 10, be provided with fine groove 101, this arranges the rigidity of energy homogenizing core piece 10, avoid producing irregular wear, promote the durability of core piece 10, increase the service life of tire.
As shown in Figure 5, the two ends pin of the V-shape of shoulder pattern block 20 is main shoulder pattern block 21 and secondary shoulder pattern block 22.The circumferential lengths L2 of the circumferential lengths L1 of main shoulder pattern block 21 and secondary shoulder pattern block 22 is all set to reduce gradually after increasing gradually to tire shoulder place near tyre surface centre plane CL place again, this arranges and will make main shoulder pattern block 21 produce less head 211, larger middle part 212 and less end 213, the circumferential lengths at middle part 212 is the circumferential lengths that are greater than head 211 and end 213, less head 211 can make main shoulder pattern block 21 more easily cut ground, improve tractive property, payload space when simultaneously larger middle part 212 promotes ground connection, promote the traveling comfort of tire running, and the less end 213 wider soil discharge channel that produces will be conducive to the lifting of tire tractive property.Same secondary shoulder pattern block 22 also produces the less head 221 of effect same, larger middle part 222 and less end 223, and the circumferential lengths at middle part 222 is the circumferential lengths that are greater than head 221 and end 223.
For improving the rigidity of main shoulder pattern block 21 and secondary shoulder pattern block 22, the end of main shoulder pattern block 21 and secondary shoulder pattern block 22 is connected to the connecting portion 23 that just forms " V " shape.Connecting portion 23 adopts a plurality of stepped side direction tractive propertys that can promote tire that arrange.For avoiding shoulder pattern block 20 to produce in the process of moving irregular wear, can on main shoulder pattern block 21 and secondary shoulder pattern block 22, be respectively arranged with fine groove 214 and fine groove 224, this arranges the rigidity of the energy main shoulder pattern block 21 of homogenizing and secondary shoulder pattern block 22, avoid producing irregular wear, promote the durability of main shoulder pattern block 21 and secondary shoulder pattern block 22, increase the service life of tire.
As shown in Figure 4, the less head 221 of secondary shoulder pattern block 22 can be set to the V word register with core piece 10, and this setting can be guaranteed the homogeneity of tyre surface ground connection, promotes the traveling comfort of tire running.For guaranteeing that tread contour has enough spoil disposal passages to realize enough tractive propertys, core piece 10 is set to 2% ~ 10% of tread contour width TW with the axial distance T5 of secondary shoulder pattern block 22.This distance can guarantee that tire protector has enough spoil disposal passages to realize enough tractive propertys.
Adopt as Fig. 1 tire tread structural style has been manufactured experimently the all-terrain vehicle tire that multiple front-wheel specification is 26X9.00R12 and they are carried out to performance testing evaluation.Traveling comfort, traction property and overall performance are that the vehicle that each testing tire is installed under the following conditions by using travels on cross-country course, and the sense organ by chaufeur evaluates traveling comfort, traction property and overall performance with method very respectively, the larger performance of numerical value is more superior.Concrete test condition is as follows.
