Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model discloses a kind of small-sized Halley's car pattern structure on tire tread, the tire tread 1
It is made up of several decorative pattern units being circumferentially evenly distributed along tire, each decorative pattern unit includes setting along tyre surface Central Symmetry successively
The longitudinal tap drain 10 put and the core block 31, interior being split to form along tyre surface Central Symmetry and the inclination counter drain 20 that is arranged alternately
It is spaced pattern block 32, outer interval pattern block 33 and shoulder lug 34.Longitudinal tap drain 10 is equal successively from tyre surface center to shoulder portion
The outer tap drain 13 of tap drain 12 and longitudinal direction is formed in tap drain 11, longitudinal direction in the longitudinal direction of cloth arrangement.Counter drain 20 is tilted across tyre surface center
And tilt and be extended along tire traveling opposite direction evagination.Tilt inclination shallow pair of the counter drain 20 by being across tyre surface center
Ditch 21 and axially external inclination depth counter drain 22 are formed.By tap drain 11 in the longitudinal direction in longitudinal tap drain 10 and tilt shallow counter drain 21
The core block 31 being split to form is triangular in shape or trapezoidal, by tap drain 12, the outer tap drain in longitudinal direction in the longitudinal direction in longitudinal tap drain 10
13 and to tilt interior interval pattern block 32, outer interval pattern block 33 and shoulder lug 34 that deep counter drain 22 is split to form be in four sides
Shape.It so may insure the endurance quality of lifting tire while tire plays good traction property when paved road travels.
As shown in Fig. 2 to realize uniform traction property, the axle of interior interval pattern block 32 when whole tire tread is grounded
It is 0.7 ~ 1.0 to the width W2 and axial width W1 of core block 31 ratio, the axial width W3 of outer interval pattern block 33
Ratio with the axial width W1 of core block 31 is 0.7 ~ 1.0, the axial width W4 and core of shoulder lug 34
The axial width W1 of block 31 ratio is 0.5 ~ 0.8, when tire running, is arranged such to form the rigidity from tyre surface center to tire shoulder
The circumferential decorative pattern row progressively to successively decrease, reduction tyre surface center pattern block row each with tire shoulder are grounded rigid difference, resistance to avoid causing
The trend of long hydraulic performance decline.The too small axial width W2 of interior interval pattern block 32, the outer interval axial width W3 of pattern block 33, shoulder
The axial width W4 of pattern block 34 will cause tyre surface both sides pattern block axial edge deficiency to cause becoming for integrally dragging hydraulic performance decline
Gesture, the excessive axial width W2 of interior interval pattern block 32, the outer interval axial width W3 of pattern block 33, shoulder lug 34 are axially wide
Degree W4 will make it that axially external decorative pattern is rigidly too strong, cause the decorative pattern inordinate wear at tyre surface center and influence overall durable
Performance.
For further lifting tire running endurance quality, the circumferential lengths L1 of the core block 31 at tyre surface center and its
Axial width W1 ratio is 1.5 ~ 3.0, and the circumferential lengths L2 and its axial width W2 of interior interval pattern block 32 ratio are 2.5
~ 4.0, the circumferential lengths L3 and its axial width W3 of outer interval pattern block 33 ratio are 2.5 ~ 4.0, the week of shoulder lug 34
It is 3.5 ~ 4.5 to length L4 and its axial width W4 ratio.So the heart is formed about more edge effect in the tread, really
The hauling ability of tire running is protected, enough pattern block rigidity are formed in tyre surface two side areas, lifts the durability of tire running.
In addition, the axial distance D and tread width TW in the longitudinal direction of tyre surface center both sides between the center line 12a of tap drain 12
Ratio be 0.45 ~ 0.55.Uniform ground connection edge can be formed from tyre surface center to both sides tire shoulder by being arranged such, beneficial to whole tire
Face realizes that balanced hauling ability can also lift overall decorative pattern durability simultaneously, the center line of tap drain 12 in too small longitudinal direction
Axial distance D between 12a will reduce the pattern block rigidity of tyre surface immediate vicinity, the easy excessive wear of generative center pattern block 31
And influence its endurance quality；And the axial distance D in excessive longitudinal direction between the center line 12a of tap drain 12 will reduce shoulder portion
Decorative pattern rigidity, outer interval pattern block 33 and the excessive wear of shoulder lug 34 also easily occurs and influences its endurance quality.Together
When, in longitudinal direction in the axial width W5 of tap drain 11, longitudinal direction the outer tap drain 13 of the axial width W6 of tap drain 12 and longitudinal direction axial width
W7 all sames.So in each axle of core block 31, interior interval pattern block 32, outer interval pattern block 33 and shoulder lug 34
Uniformly circumferentially drainage space is formed to wall, while can also form identical decorative pattern ground connection edge, it is ensured that enough hauling abilities.
As shown in Figure 2, Figure 3, Figure 4, axles of the axial angle α 1 of the shallow tail end of counter drain 21 with tilting the deep tail end of counter drain 22 is tilted
It it is 20 ° ~ 40 ° to the difference of angle [alpha] 2.Tyre surface center can be reduced to the resistance of water drainage of tire shoulder by being arranged such, it is ensured that tire is in wetland
Good hauling ability can be played during upper traveling.Shallow counter drain 21 is tilted to be located at tyre surface center and tilt rising for shallow counter drain 21
Top is mutually communicated with tap drain 11 in the longitudinal direction of tyre surface both sides, to ensure enough firm of the core block 31 of tyre surface immediate vicinity
Property, the endurance quality of lifting tire in the process of moving, tilt depth H 2 of the depth H 1 of shallow counter drain 21 with tilting deep counter drain 22
Ratio be 0.3 ~ 0.5.The depth H 1 of the excessive shallow counter drain 21 of inclination will reduce the rigidity of core block 31, in tire row
Sail and easily occur to destroy and influence overall endurance quality；Conversely, the depth H 1 of the too small shallow counter drain 21 of inclination will make center
Pattern block 31 can not effectively play edge effect, influence its hauling ability on the contrary.
The small-sized Kazakhstan that a variety of front and back wheel specifications are 11X6.00-5.5 has been manufactured experimently using such as Fig. 1 tyre treads structural style
Thunder wheel tire simultaneously carries out performance test to them and evaluated.Traction property, durability and overall performance are by being provided with testing wheel
Small-sized Halley's car of tire is travelled on route mating formation.By the sense organ of driver respectively using conventional case as 100 points of evaluation traction properties
And overall performance, and the degree of wear of visual tire tread block outward appearance evaluates its endurance quality, the bigger performance of numerical value after test
It is more superior.
Test result such as following table：
It is can confirm that by test result using after this tread patterns designed, it can be ensured that tire is when paved road travels
The endurance quality of tire is lifted while playing good traction property.
It is described above, only the utility model preferred embodiment, not with this limit the utility model implementation scope, according to this
The equivalent changes and modifications that the technical scheme and description of utility model are made, should all belong to the model that the utility model is covered
Enclose.
