Detailed description of the invention
As shown in Fig. 1 to Fig. 6 B, present invention is disclosed a kind of Cross-country tire tread pattern structure, by a plurality of decorative pattern cell distribution in tire protector, each decorative pattern unit comprises along the core block group of tire circumference distribution and the pattern block on tire shoulder group along the distribution of tire circumference, two pattern block on tire shoulders 4 that one is long and the other is short are spaced apart in shoulder circumference, each core block 1 with adopt reinforced rib 3 to be connected between pattern block on tire shoulder 4 and form the decorative pattern framework of zigzag, be transversely provided with bottom of trench fin 5 in each tire shoulder groove bottom 8; The circumferential dual-side of pattern block on tire shoulder 4 is step-like design, and outer face is overlapped by upper surface 6 and 7 two, lower surface end face and formed.
Each pattern block on tire shoulder group is made up of the pattern block on tire shoulder 4 being positioned at core block group both sides, two pattern block on tire shoulders 4 being crisscross arranged symmetrically, and the adjacent two core blocks 1 of the inner end surface of each pattern block on tire shoulder 4, and week forwards, backwards both sides be arc setting in the same way.
Coordinate shown in Fig. 1, Fig. 2 as Fig. 3 C, form zig-zag traverse furrow 2 between each group switching centre pattern block group, this jagged traverse furrow, while lifting traction force, can strengthen again the effect of anti-sideslip, particularly contribute to improving propulsive effort when tire is turned, and then turn to ensureing tire fast and stable.
The degree of depth of zig-zag traverse furrow 2 is H, and depth H is 6% ~ 15% of tread width TW; The width of zig-zag traverse furrow 2 is a, and width a is 3% ~ 12% of tread width TW, is preferably 4% ~ 8%, and larger furrow width design can improve the draining spoil disposal performance of decorative pattern, strengthens the tractive force of soft surface.
As shown in Figure 4, because core block 1 is little block-type tread, for prevent tire in motion core block 1 impacted and fallen block, core block 1, pattern block on tire shoulder 4 by reinforced rib 3 be connected, continuous print reinforced rib 3 forms zigzag structure on tyre surface, continuous print zigzag reinforced rib makes core block 1 as a whole with pattern block on tire shoulder 4 one-tenth, and then strengthen the rigidity of core block 1, generally while the performances such as each groove draining spoil disposal of raising, in turn ensure that the rigidity of each pattern block, promote it and resist to fall block performance.
As Fig. 3 A coordinates shown in Fig. 1, described reinforced rib 3 is distributed in groove bottom, and it has certain height h, and its height h is 15% ~ 25% of zig-zag traverse furrow 2 depth H, reinforced rib 3 can improve tractive property in muddy road conditions, and can strengthen the anti-puncture ability in groove region; When reinforced rib 3 height h design is excessive, is unfavorable for the draining of decorative pattern, and easily affects the in-use performance in tire later stage, when reinforced rib 3 height h design is too small, its stiffening effect is not obvious, and pattern block is easily impacted and comes off, and affects the service life of tire.
Coordinate shown in Fig. 5, Fig. 6 A, shoulder portion ring circumference is equally spaced dispersed with pattern block on tire shoulder 4, and pattern block on tire shoulder 4 is large, high, arch, acceleration capability when contributing to curved; Pattern block on tire shoulder 4 weeks forwards, backwards both sides is step-like design, and as shown in figure D-D ', this step-like design adds edge effect when tire drives, and contributes to the tractive property improving tyre shoulders, can improve shoulder spoil disposal again; The epimere Sidewall Height of step-like design is b, b is 20% ~ 50% of tire shoulder groove 9 ditch depth c, when epimere Sidewall Height b is excessive, tire shoulder decorative pattern rigidity is more weak, be unfavorable for the excessively curved rapidly of tire, even easily cause tire shoulder to fall block, when epimere Sidewall Height b is too small, its tractive property promote and not obvious, and be unfavorable for the spoil disposal of shoulder.The angle of inclination of epimere Sidewall angles and hypomere sidewall is W, and its size is set to 5 ° ~ 18 °.
Join as shown in Fig. 5, Fig. 6 B, the upper surface 6 of pattern block on tire shoulder 4 outer end is 15 ° ~ 45 ° with the angle f of tread surface normal, lower surface 7 is 5 ° ~ 20 ° with the angle g of tread surface normal, the cooperation of upper surface 6 and lower surface 7 makes the rigidity of pattern block on tire shoulder end face strong, when tire is absorbed in silt road surface, the upper surface 6 of pattern block on tire shoulder 4 and lower surface 7 can provide additional propulsive effort in side, strengthen the moment propulsive effort of tire.
Again as shown in Figure 1, the circumference of all adjacent two pattern block on tire shoulders 4 is forwards, backwards spaced apart L, and its interval L is 10% ~ 35% of tread width TW, is preferably 15% ~ 25%; When interval L is too small, shoulder portion draining, spoil disposal are easily influenced; When interval L is excessive, tractive property can decline, particularly Ackermann steer angle, and pattern block on tire shoulder can not provide a good curved booster action of mistake.Adjacent two pattern block on tire shoulder 4 length differences of tyre surface circumference are P, and length difference P is 3% ~ 10% of tread width TW; Length difference P arrange taken into full account the road conditions of various complexity, can promote shoulder portion by performance, be conducive to the lifting at various different road conditions shoulder portion tractive force, when interval P is too small, its lifting traction force DeGrain; When interval P is excessive, the wear hardness of tire shoulder can be affected, and easily reduce the tractive property of pattern block on tire shoulder.
Coordinate shown in Fig. 3 B as Fig. 1, the tire shoulder groove bottom 8 formed between the pattern block on tire shoulder 4 at interval, which is provided with bottom of trench fin 5, bottom of trench fin 5 is that isoceles triangle shape is protruding, it has certain height K, and height K is 15% ~ 40% of zig-zag traverse furrow 2 ditch depth H, and bottom of trench fin 5 can promote point mud, the spoil disposal performance of tire, when tire is absorbed in muddy road conditions, can effective lifting traction force.
Because the spacing L between pattern block on tire shoulder 4 is wider, the center rigidity of tire shoulder groove bottom 8 is relatively weak, tire is easily destroyed by puncture in motion, and then affect Using Life of Tyre, bottom of trench fin 5 is arranged on the center of tire shoulder groove bottom 8, and it is the projection of isoceles triangle shape, can strengthen the rigidity of tire shoulder groove bottom 8, make its not easily puncture by stone, improve the service life of tire.
In a word, tire tread of the present invention belongs to non-guide decorative pattern, and it is mainly applicable to site for car racing match, and than design, (land is compared: the ratio of the finger wheel tire tread pattern block actual ground connection gross area and total ground contact area in decorative pattern overall land.) less, its land ratio is 30% ~ 50%, and sea, center is more relatively large than [sea ratio: (1-land ratio) X100%], its tyre surface center covering property and draining, spoil disposal performance can be increased, another continuous print reinforced rib 3 designs and pattern block on tire shoulder 4 step-like design, and coordinate the effect of bottom of trench fin 5, while lifting traction force, its draining, spoil disposal can be ensured again and resist to fall the performances such as block, especially comparatively remarkable to the lifting of place match tire flipper turn performance, take into account the performance that place match requires each side generally.
