Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in Fig. 2,3 and 5, a kind of UHP tires of the multi-functional tyre surface shape of the mouth as one speaks, it includes tyre surface 1 and tire shoulder 2, the tire
Shoulder 2 is located at the both sides of tyre surface 1, and tyre surface 1 and tire shoulder 2 are integrated；The inner side of tyre surface 1 and tire shoulder 2 is equipped with base rubber 3, and should
The outside of base rubber 3 is provided with projection 31；The position of respective protrusions 31 is provided with opening 11 on the tyre surface 1；Wherein described raised 31 and right
It should be open and 11 be adapted；The outside spacers of tyre surface 1 are provided with pattern groove 12 and intermediate mass 13；Intermediate mass 13 because narrower, and
The extension of tire during inflation, the ground pressure of intermediate mass 13 is generally larger, and contact of the intermediate mass 13 with tire is more densely cross-linked, then will
Opening 11 on tyre surface 1 may be such that the electric conductivity of tire is more preferable through intermediate mass 13 is located at.
The tyre surface 1 intersects at intermediate mass 13 with equatorial plane D；And to be symmetrically set in tire red for the opening 11 on tyre surface 1
Road face D both sides certain distance；And the distance is red for equatorial plane D and the outer wall of the first pattern groove 121 distance values L5 and tire
The road face D and inwall L6 of the second pattern groove 122 distance values and half.
The cross section of the upper shed 11 of tyre surface 1 is in isosceles trapezoid.Because bottom width W1 influences whether to take turns in the opening of tyre surface 1 11
The resistive performance of tire, when the upper too narrow electric conductivities of bottom width W1 can not maximize；When upper bottom width W1 is too wide, base rubber 3 and the glue of tyre surface 1
Color has Light Difference, has influence on the outward appearance of tire；Therefore the upper bottom width W1 of the UHP tires opening 11 scope is 1.5-3mm,
The lower bottom width W2 of tire opening 11 scope is 2.5-5mm；Chi can be chosen according to different performance requirements and sizing material extrusion technique
Very little fluctuation.
The tire shoulder 2 is curved in the section of tyre equatorial, and wherein the inner side of tire shoulder 2 corresponds to A, and the outside of tire shoulder 2 is corresponding
For B, there is peak C in the tire shoulder 2, and peak C is corresponded in the tire tread 1 and the innermost traverse furrow arc length of tire shoulder 2
Point；
Wherein, thickness of the outside B points of tire shoulder 2 apart from the bottom of base rubber 3 is H2=2 × L2/ (L1+L2) × Mmm, tire shoulder 2
Thickness of the upper C points apart from the bottom of base rubber 3 is H3=2 × L1/ (L1+L2) × Mmm, and dimensional tolerance is 0.5mm；Wherein,
L1 is the length that the inner side A points of tire shoulder 2 arrive C points, and L2 is the length of C points to the outside B points of tire shoulder 2, and M is tyre surface end dot thickness, and M
=N* (1.01.1)* δ±0.5mm；Wherein, N is that the dispensing of tire section finished product tyre surface end is thick, 1.01.1 coefficients are beaten for shaping
Moulding material deflection, δ are rubber vulcanization constriction coefficient (relevant with sizing material self attributes), and 0.5mm is that sizing material extrudes undulating value.
Because base rubber thickness H4 has influence on high speed, rolling resistance, the performance such as resistance of UHP tires, and in order to ensure base rubber
Marked no more than abrasion, and do not influence the unification of appearance color when tire has finally been ground, base rubber thickness H4 scopes are 0.5-
1.5mm, it can be selected according to different performance requirements.
In tire design and in the case of having a fling at identical, traditional tyre surface die design is without base rubber 3, the utility model wheel
The base rubber 3 of tire has the characteristics of low-heat-generation, rolling resistance Experimental Comparison is carried out, from table 1 below as can be seen that the UHP tire tread mouths
Type design about reduces by 1.31% relative to traditional tyre surface die design rolling resistance, and the coefficient of rolling resistance of tire is low, vehicle traveling
During more save oil consumption, reduce the discharge of CO2 and heat.
Table 1
| Project | Traditional tyre surface | The utility model tyre surface |
| Rolling resistance (N/KN) | 9.29 | 9.17 |
The characteristics of existing glue kind of tyre surface 1 causes resistance big because white carbon is more, and base rubber 3 is conductive good, pass through
Projection 31 set by the outside of base rubber 3, inside tires structure can be communicated, the resistance of tire is advantageously reduced, under with ground
Table 2 as can be seen that tyre surface die design of the present utility model reduced relative to traditional tyre surface die design resistance it is very more, can
With effectively charge guiding caused by vehicle to ground, and then improve the security performance of vehicle traveling.
Table 2
| Project | Traditional tyre surface | The utility model tyre surface |
| Resistance RA (Ω) | 1.366×108 | 9.551×104 |
As shown in figure 4, the thickness h 5 of base rubber 3 and h6 of traditional tire shoulder 2 differ greatly.As shown in Fig. 5, the utility model
Thickness H5 and the H6 difference of base rubber 3 of tire shoulder 2 is little；Then it can make it that flowing is more uniform so that tire in vulcanization for sizing material
The traverse furrow ditch primer transition of shoulder 2 is uniform.
In the case of tire operating mode identical, the thickness of base rubber 3 of only tire shoulder 2 is different, carries out CAE decorative pattern stiffness Analysis.
Traditional tyre surface die design FEA analyses show that maximum ground contact pressure is 0.620Mpa；FEA points of the utility model tyre surface die design
Analysis shows that maximum ground contact pressure is 0.577Mpa；The utility model is grounded red highlight regions and is less than traditional tyre surface die design
FEA analysis results；Then understand that the utility model make it that the stress transition of tire shoulder 2 is uniform, ground pressure is small, helps to be lifted
The high speed performance and wear hardness of tire.
The utility model provides a kind of UHP tires of the multi-functional tyre surface shape of the mouth as one speaks, and its rolling resistance is low, and then energy-conserving and environment-protective；
Resistance is low, can be advantageous to lift the security that vehicle travels effectively charge guiding caused by vehicle to ground；Reduce tire
Ground pressure, lift the high speed performance and wear hardness of tire；Handling, the low resistive of tire can effectively be balanced
Energy, the resistive energy of low rolling, high speed performance, enrich the usage experience of UHP tires, have good economic benefit.
General principle, principal character and advantage of the present utility model has been shown and described above.The technical staff of the industry
It should be appreciated that the utility model is not restricted to the described embodiments, the simply explanation described in above-described embodiment and specification is originally
