Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail, is describing each implementation of the present invention in detail
Before the technical scheme of example, involved noun and term are explained, in this manual, title is identical or label phase
Same part represents similar or identical structure, and is only limitted to the purpose illustrated.
As shown in Fig. 2 the low noise pneumatic tire includes tyre surface, offered on the tyre surface and extended along tire circumferential direction
Four circumferential grooves, and a plurality of lateral trench extended to tire width direction outside, the circumferential grooves and horizontal ditch
Tyre surface is divided into multiple block-type treads by groove.
The block-type tread includes inside shoulder block, inner side by central block, intermediate mass, outer successively by tire inner side to outside
Central block and peripheral shoulder block are leaned in side, and setting inside shoulder block and inner side are δ by circumferential misalignment distance between central block1, inner side
Circumferential misalignment distance is δ between shoulder blocks and intermediate mass2, inside shoulder block and outside are by circumferential misalignment distance between central block
δ3, circumferential misalignment distance is δ between inside shoulder block and peripheral shoulder block4, meet following relation：0.06≤δ1/PX_avg≤
0.09、0.26≤δ2/PX_avg≤0.31、0.39≤δ3/ PX_avg≤0.44 and 0.13≤δ4/ PX_avg≤0.17, wherein
PX_avg is the average value of pattern pitch, reference picture 2 and Fig. 3.By outside shoulder blocks, interior outside in control by central block and
Mutual circumferential misalignment distance between five pattern blocks such as intermediate mass, can control pattern block at the ground connection impression forward position of complete cycle tire
The amplitude of variation of the impact between road surface, it is to avoid the unexpected concentration of time domain acoustic energy, so as to impact noise amplitude be controlled
In relatively small scope, and then the purpose of noise reduction is reached, reference picture 4.
Circumferential misalignment ratio between control tire tread block, can reach the purpose of noise reduction, and specific principle of noise reduction is as follows：Wheel
The tire noise that tread block clashes into road surface generation when being grounded and being liftoff in rolling process is the important sources of tire noise,
(a) and (b) in Fig. 4 is respectively the ground connection impression schematic diagram of the two kinds of tires that do not misplace and misplace.From in Fig. 4 (a), being grounded
Edge is consistent with the trend of lateral trench before and after impression, and now tire is smaller to the effect of impact on ground at ground connection impression forward position,
But with the rolls forward of tire, when pattern block is contacted with ground, shown in such as Fig. 4 (c), now taken turns at ground connection impression forward position
Tire increases suddenly the effect of impact on ground, therefore in the rolling process of complete cycle tire, road surface occurs with ground connection impression forward position
Sudden surge is acted on, and so as to cause the unexpected concentration of time domain acoustic energy, peak value higher is produced, shown in such as Fig. 4 (e)；In wheel
After tire carries out circumferential misalignment, in the various location (shown in such as Fig. 4 (b) and Fig. 4 (d)) of complete cycle tire, in ground connection impression forward position
The percussion fluctuation for locating tire tread road pavement is relatively small, and time domain acoustic energy more disperses, and acoustic energy peak value is smaller, such as Fig. 4 (f)
It is shown, so as to reach the purpose of noise reduction.The inside shoulder block and inner side are by circumferential misalignment, the inside shoulder block between central block
Circumferential misalignment, inside shoulder block and outside between intermediate mass is by the circumferential misalignment between central block, and inside shoulder block
Calculated in units of a pattern pitch with the circumferential misalignment between peripheral shoulder block.
As shown in Fig. 2 the circumferential grooves include the first shoulder circumferential slot 61, first centrally circumferentially groove 62, second successively
The centrally circumferentially shoulder circumferential slot 64 of groove 63 and second.The lateral trench includes first the 71, first center of shoulder transverse groove laterally
The central shoulder transverse groove 74 of transverse groove 73 and second of groove 72, second.The steel disc stria includes being arranged on inside shoulder block
First stria 81, the second stria 82 and first longitudinal direction stria 91, are arranged in inner side by the 3rd stria 83 and the 4th in central block
Stria 84, is arranged in the 5th stria 85 and the 6th stria 86 on intermediate mass, is arranged in outside by the 7th stria in central block
87, and it is arranged in the 8th stria 88 and second longitudinal direction stria 92 on peripheral shoulder block.
In order to strengthen the wetland drainage performance of tire, the first shoulder transverse groove 71, the second shoulder transverse groove 74 are distinguished
Connected with its circumferentially upper adjacent shoulder transverse groove by first longitudinal direction stria 91, second longitudinal direction stria 92.
To adjust the frequency noise of tyre tread section, the stria 88 of first stria 81 and the 8th is respectively positioned on circumferential adjacent
Two centre positions of shoulder transverse groove.
The stria 82 of first stria 81 and second is identical with the arranged direction of the first shoulder transverse groove 71, and the described 8th is thin
Groove 88 is identical with the arranged direction of the second shoulder transverse groove 74.
Arranged direction of 3rd stria 83 with the first central transverse groove 72 near the first shoulder circumferential slot side is identical,
The arranged direction of 4th stria 84 and the first central transverse groove 72 near the first centrally circumferentially groove side is identical.
5th stria 85 is identical with the arranged direction of the 6th stria 86.
7th stria 87 is identical with the arranged direction of the second intermediate lateral groove 73.
The above implementation method is only that the preferred embodiment of the present invention is described, not to model of the invention
Enclose and be defined, on the premise of design spirit of the present invention is not departed from, those of ordinary skill in the art are to technical side of the invention
Various modifications and improvement that case is made, all should fall into the protection domain of claims of the present invention determination.
