Description
Technical field
The utility model relates to tyre technology, particularly the airtyred tread pattern structure of one.
Background technology
Tire is as the carrier of running car, and rely on the friction on tread contour and ground, the traveling of driving automobile, therefore tire is higher for the requirement of strength of tread contour.For band tire, design comparatively conventional at present arranges cross groove 1 ' on tyre surface, and be usually designed to " tobacco pipe shape " (as shown in Figure 1), although can ensure that tire has preferably propulsive effort and braking force like this, but the stressed same increasing of its pattern block, pattern block distortion particularly after the stressed superposition in pattern block edge, the Qu Rao of bottom of trench is easily caused to tear, transversely chap, continue to travel the then slight crack degree of depth to grow up, cause the destruction of whole pattern block, even fall block, thus cause the earlier period damage of tire, affect the service life of tire.
Utility model content
The purpose of this utility model is to provide a kind of air tread pattern structure, and it can change the Impact direction at pattern block edge, avoids the superposition of power, reduces the distortion of pattern block, thus promotes Using Life of Tyre and resistance to year performance.
For achieving the above object, the utility model is by the following technical solutions:
A kind of air tread pattern structure, by a pair circumferentially and axially symmetrical, and the cross groove be dislocatedly distributed, form along tire protector circumference is spaced apart, it is characterized in that: described cross groove is made up of in four regions first area, second area, the 3rd region and the 4th region respectively from tire shoulder to tyre surface center totally, and first area, second area and the 3rd region extend vertically, the 4th region circumferentially.
Preferably, the angle that the edge of described first area and tire circumference are formed is 75 ° ~ 105 °, the angle that the edge of described first area and the edge of second area are formed is 145 ° ~ 165 °, the angle that the edge of described second area and the edge in the 3rd region are formed is 120 ° ~ 145 °, and the angle that the edge in described 3rd region and four-range edge are formed is 100 ° ~ 130 °.
More preferably, the width at the top of described first area is L1, the width of described second area and joint, first area is L2, the width of described 3rd region and second area joint is L3, the width of described 4th region and the 3rd joint, region is L4, the width of described four-range end is L5, the ratio of L1, L2, L3, L4 and L5 is 3.9 ~ 4.5:3.5 ~ 4.1:3.0 ~ 3.6:2.2 ~ 3.0:1, and meets L1 > L2 > L3 > L4 > L5.
After adopting technique scheme, the utility model is compared with background technology, and tool has the following advantages:
The utility model can change the Impact direction at pattern block edge, avoids the superposition of power, reduces the distortion of pattern block, strengthens the rigidity of tire protector, thus promotes Using Life of Tyre and resistance to year performance.
Accompanying drawing explanation

Fig. 2 is the airtyred tread pattern structure schematic diagram of the utility model.
Fig. 3 is the partial schematic diagram of the utility model cross groove.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment
Refer to Fig. 2, the utility model discloses a kind of air tread pattern structure, comprise tyre surface A, tyre surface A is provided with a pair cross groove 1, wherein:
Shown in figure 2, a pair cross groove 1 lays respectively at the both sides of circumferential line B, and vertically and circumference symmetrical, and to shift to install.In the present embodiment, often pair of cross groove 1 is in being uniformly distributed along tire circumference at equal intervals.
Each cross groove 1 is made up of in four regions first area 11, second area 12, the 3rd region 13 and the 4th region 14 to tyre surface center respectively tire shoulder totally, and first area, second area and the 3rd region are along tire shoulder to tyre surface center shaft to extension, 4th region extends along tire circumference, wherein:
Coordinate shown in Fig. 2 and Fig. 3, the angle [alpha] that edge 3 and the tire circumference 21 of first area 11 are formed is 75 ° ~ 105 °, the angle beta that edge 3 and the edge 4 of second area 12 of described first area 11 are formed is 145 ° ~ 165 °, the angle γ that the edge 4 of described second area 12 and the edge 5 in the 3rd region 13 are formed is 120 ° ~ 145 °, the angle δ that the edge 5 in described 3rd region 13 and the edge 6 in the 4th region 14 are formed is 100 ° ~ 130 °, by the restriction to above-mentioned angle, the shape of groove can better be limited, thus can wear hardness be promoted, tractive property and skidding behavior.In addition, 4th region 14 is designed to roughly the same with the travel direction of tire, can reach the effect of anti-side sliding to a certain extent, and suffered transverse force is decomposed by first area 11, second area 12, the 3rd region 13, reach the effect of dispersive stress, reduce the eccentric wear of tire.
Coordinate shown in Fig. 2 and Fig. 3, the width at the top 21 of first area 11 is L1, second area 12 is L2 with the width of joint, first area 11 22, 3rd region 13 is L3 with the width of second area 12 joint 23, the width of the 4th region 14 and the 3rd joint, region 13 24 is L4, the width of the end 25 in the 4th region 14 is L5, L1, L2, L3, the ratio of L4 and L5 is 3.9 ~ 4.5:3.5 ~ 4.1:3.0 ~ 3.6:2.2 ~ 3.0:1, and meet L1 > L2 > L3 > L4 > L5.Like this by limiting the width parameter of groove, rigidity and the resistance to year performance of tire protector can be ensured.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
