Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
Please refer to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the present invention provides a kind of high-performance low rolling resistance tire: including carcass 1, tire shoulder
2, crown 3, the heat dissipation of longitudinal furrow groove 4, first cutter groove 5, connection groove 6,1 upper end two sides of carcass are tire shoulder 2, and tire shoulder 2 is up
3 part of crown, it is main groove, 4 outside of longitudinal furrow groove that the longitudinal furrow groove 4 that four are circumferentially arranged is provided in the middle part of crown 3
The first heat dissipation cutter groove 5 is provided on the pattern block of formation, opening up between longitudinal furrow groove 4 is adjacent is in 59 ° of oblique cross connection with it
Crown pattern block is divided into wedge-shaped pattern block by groove 6, and 3 radius of crown is 100mm, tread width and section width ratio
0.7651 is taken, hat arc-height and section ratios 0.0287,4 ditch depth of longitudinal furrow groove are 15mm, and bottom is round and smooth excessively, and is arranged
There is bar shaped to shoot pebbles with a catapult boss 41, the first heat dissipation 5 depth of cutter groove is 12mm, and the groove depth of connection groove 6 is 4 depth of longitudinal furrow groove
1/5~1/4, the pattern block of tire shoulder 2 is closed, and the second deep heat dissipation of 2.5mm is uniformly opened up on the pattern block of tire shoulder 2
Cutter groove 21.
Working principle: the longitudinal furrow groove that tyre tread is circumferentially arranged with four be main groove, decorative pattern ditch depth 15mm,
Decorative pattern channel bottom is round and smooth excessively to avoid stress from concentrating, and is provided with bar shaped and shoots pebbles with a catapult boss, and pattern block edge uniformly opens up
The heat dissipation cutter groove of 12mm depth connection decorative pattern tap drain can be effectively reduced the heat generated during tire used, prevent tire early
Phase damage, improves service life；Being opened up between adjacent longitudinal furrow groove with longitudinal furrow groove is in 59 ° of oblique cross connection groove,
Crown pattern block is divided into wedge-shaped pattern block, both ensure that good pattern block integral rigidity in this way, reduces rolling resistance, again
