Description
Technical field
The utility model belongs to tyre tread technical field, and in particular to a kind of tire tread flower for being provided with anti-stone structure
Line.
Background technology
Pneumatic tire is configured with circumference, radial direction groove and the grounding parts being respectively partitioned into by groove in its tread portion
Position, so as to form the decorative pattern for meeting tyre performance and use condition requirement.When tire is deposited when there is the poor road surface row such as stone to relax
In problems with.Stone enters in pneumatic tire groove, and because ground connection position is by torsional deformation under load, stone is difficult row
Go out.Different size of stone enters bottom of trench gradually after entering groove, damages bottom of trench and may damage belt, causes event
Barrier, influences Life of Tyre.
Therefore pneumatic tire sets the tread structure of anti-horsestone, and its bottom of trench for being mainly in the circumferential groove of tire is installed additional
Row Shitai County, radius size is gradual change from the bottom up for the row Shitai County, the effect with accumulation of energy, make folder enter tap drain stone it is final to
The outside of tap drain is driven out of, discharges it, and improves the lithagogue effect of tire tread.
Publication No. is disclosed on groove projecting point for the patent of CN101646572 A, by multiple equilateral triangles
Form a surface for fixed rolling so that stone is easy to be discharged from groove.
Disclosed in the patent of US2014/0299243 A1 by setting easily deformable rubber door in ring-shaped groove,
The air current flow during tire running is reduced, so as to reduce noise to a certain degree.
But above-mentioned anti-stone structure, the in use root of stress easily Shitai County of the row of concentrating on, or even this can be cut off
Row Shitai County, makes bottom of trench have slight crack to produce, and locally injures belt, it is impossible to ensures that tire has preferably anti-horsestone effect, still deposits
The defect of tyre life is influenceed in horsestone.So, the anti-stone structure of tire need to be improved.
The content of the invention
To solve the above problems, the utility model provides a kind of tire tread pattern for being provided with anti-stone structure.
The purpose of this utility model is realized in the following manner:
A kind of tire tread pattern for being provided with anti-stone structure, including tread contour, the tread contour is by circumferentially connecting
Continuous annular groove and pattern block are constituted, and annular groove is defined by discontinuous first incline, and relative first incline is recessed in annular groove
Part be provided with the first polygon surface parallel to tyre surface, the second incline of the first polygon surface and the 3rd incline are distinguished
Along bottom of trench direction extend and form two the second polygon surfaces, described two second polygon surfaces and the first polygon table
Face shares a summit S;The bottom land lines of annular groove is "the" shape circumferentially.
The summit S is T with the vertical range of annular groove bottom, and tyre surface is TD, TD with the vertical range of annular groove bottom
≤4T。
Two the second adjacent polygon surfaces share a sides, wherein recessed side is turning line, turning line with
The angle of vertical direction is α 1, and the second polygon surface is 5- with the span that the angle of vertical direction is α 2, α 1 and α 2
45°。
Horizontal range between two adjacent turning lines is H, and the horizontal range between two the first relative inclines is
D, H≤3D.
Horizontal range H between all adjacent turning lines is unequal.
Relative to prior art, the utility model provides a kind of tire tread pattern for being provided with anti-stone structure, arranges masonry
With being mainly reflected in two aspects:On the one hand first polygon surface parallel with tyre surface directly plays a part of to arrange stone, another
The inclined surface that aspect passes through annular groove both sides, the angle of inclined surface is change, and stone is hardly formed stabilization wherein
Fixing point, is easy to discharge, it is ensured that tire has good row's stone performance during tire running;Ensure that tire has good
With good noise-reducing performance while anti-wear performance.In addition, the row's masonry for being designed to realize tire of summit S is used, together
When projection between can partly stop air current flow during tire running, so as to play a part of noise reduction.Additionally, more than first
Side shape surface is parallel with tyre surface, can play forewarning function to the abrasion of tire abnormal in early stage;Using change between adjacent turning line
Width design, so as to the pitches for reaching differentiation are designed, can reduce tyre noise.
Brief description of the drawings
Fig. 1 is the structural representation of tread contour of the present utility model.
Fig. 2 is the sectional view in Figure 1A-A directions.
Fig. 3 is the sectional view in Figure 1B-B directions.
Wherein, 1 is tread contour;2 is annular groove;3 is pattern block;4 is the second incline;5 is bottom land lines;6 is first
Incline;7 is turning line;8 is the first polygon surface;9 is the second polygon surface;10 is the 3rd incline.
Specific embodiment
As illustrated in the accompanying drawings from 1 to 3, a kind of tire tread pattern for being provided with anti-stone structure, including tread contour 1, the tyre surface
Decorative pattern 1 is made up of annular groove 2 continuously in a circumferential and pattern block 3, and annular groove 2 is defined by discontinuous first incline 6, annular groove
The part recessed with respect to the first incline 6 is provided with the first polygon surface 8 parallel to tyre surface in 2, the first polygon surface 8
Second incline 4 and the 3rd incline 10 along bottom of trench direction extend and form two the second polygon surfaces 9, described two the respectively
Two polygon surfaces 9 and the first polygon surface 8 share a summit S;The bottom land lines 5 of annular groove 2 is " it " circumferentially
Font.
First incline 6 is tyre surface and the intersection of the first polygon surface 8 rib concordant with tyre surface.
The vertical range of summit S and the bottom of annular groove 2 is T, and tyre surface and the vertical range of the bottom of annular groove 2 are TD, TD≤
