Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Embodiment
As shown in Figures 1 and 3, CL is circumferential line, and tire includes tyre surface 1, sidewall 2 and tire lip 3.Tyre surface 1 is equipped with
The circumferential groove group being symmetrically distributed at left and right sides of circumferential line, each circumferential direction groove group includes by tread center towards tire shoulder
The the first circumferential groove 12 of circumferential groove 11, second and third circumferential direction groove 13 that direction is successively arranged, each circumferential flower
Groove group designs from shallow to deep from the ditch depth from tread center to tire shoulder.Because of the first circumferential flower of circumferential groove 11, second
Groove 12 in ground area, depth H 1 using etc. deep design, and since thickness is too thick at tire shoulder, so the at tire shoulder
Three circumferential grooves 13 are using gradually deep design, ditch depth H1 and the third week of the first circumferential groove 11 and the second circumferential groove 12
Ratio to the ditch depth H2 of groove is 70%-85%.When designing the ditch depth of third circumferential direction groove 13, if depth design obtains
Too shallow, then the sizing material thickness at the position is too thick, and thermal diffusivity is poor, and endurance quality is undesirable, if ditch depth is designed too deep, the portion
The sizing material thickness of position is too thin, and tread rigidity is insufficient, and when the vehicle is running, tire can not support load.
For the heat dissipation performance for further increasing tyre surface 1, as shown in Figure 2 and Figure 3, the side wall of each circumferential groove of tyre surface is equipped with
By concave edge face 14a and the concave-convex drop groove 10 that is formed by overlapping of flange face 14b with drop.Concave edge face 14a by
Tyre surface is drawn, and flange face 14b is drawn by bottom of trench, and the lap-joint M of the two is groove ditch depth H1 away from the radial depth H3 of tyre surface
50%-85%.The concave edge face of concave-convex drop groove 10 by the upper straight line A1 that is connected with tyre surface and with bottom of trench flange face
The lower straight line A2 composition of 14b linking, the connecting points N of the upper straight line A1 and lower straight line A2 are the most deep of concave edge face 14a indent
Place, the bosom are arranged in concave-convex drop groove 10.The upper straight line is by tyre surface 1 to the hollow depth of itself and connecting points N
H10 gradually changes deeply in 0mm-1.5mm.It is arranged such, it can be ensured that 1 intensity of tyre surface, and the thickness of tyre surface 1 is reduced, and roll in tire
Bumps drop groove 10 can radiate to the sizing material in circumferential groove when dynamic, flowed using air and improve dissipating for tyre surface 1
Hot property, to promote tire endurance quality.Similarly, the sidewall design of groove described in the present embodiment is equally applicable for tilting
Lateral ditch.
In order to improve the heat dissipation performance on sidewall 2, in conjunction with shown in Fig. 1, Fig. 4 and Fig. 5, by sidewall 2 by towards sidewall indent
Inside arc 21 and lateral arcs 22 several sidewall bumps drop pattern blocks 20 made of sketching the contours are formed by overlapping, to ensure sidewall decorative pattern
Block edge is played a supporting role in load.Simultaneously to ensure the intensity on sidewall 2, sidewall bumps drop pattern block 20 it is inside and outside
The starting point A of side arc 21,22 is set as the 45%- of tire section height H4 to the radial distance H5 between tire overall diameter diameter point B
The radial distance H6 of 55%, sidewall terminal C to tire diameter diameter point D are the 15%-25% of tire section height H4, inside arc 21
Endpoint E be bosom, the bosom be arranged in sidewall bumps drop pattern block 20.
The radial depth H7 of the starting point A to endpoint C of sidewall bumps drop pattern block 20 is gradually set deeply from upper and lower two side to center
Meter, depth H 7 is by 0mm gradual change to 3mm, and the endpoint C of 21 endpoint E of inside arc and lateral arcs is using oblique line connection, and inside arc 21
Connection with oblique line is arranged using circular arc.It, can by optimizing the position distribution and ditch depth design of sidewall bumps drop pattern block 20
Ensure 2 intensity of sidewall, reduce the thickness on sidewall 2, improve the heat dissipation performance on sidewall 2, promotes tire endurance quality.
For the heat dissipation performance for further increasing sidewall 2, bumps drop pattern block 20 circle in sidewall is equidistantly configured, such as
Shown in Fig. 4 and Fig. 5, along tire sidewall tangential direction, the section of sidewall bumps drop pattern block 20 is right angled triangle, inside arc
Spacing W1 between 21 and lateral arcs 22 is 10mm-25mm, if W1 width is too wide, the intensity on sidewall 2 is too weak, and tire can not support
The load of vehicle, if W1 width is too narrow, thermal diffusivity is bad, and endurance quality is undesirable.The circumferential direction of sidewall bumps drop pattern block 20
Depth H 8 is using by deep gradually shallow setting, and circumferential depth H 8 is by 3mm gradual change to 0mm.
As shown in figure 4, sidewall bumps drop pattern block 20 is arranged using arc surface, arc radius in terms of tire side
R1 is 90mm-115mm, while the distributed number of the sidewall bumps drop pattern block 20 of circle changes according to specification and mutually strains
Change, if the number of sidewall bumps drop pattern block 20 is too many, the width W1 of circumferential bumps drop pattern block 20 is smaller, thermal diffusivity
Bad, endurance quality is undesirable, if the number of sidewall bumps drop pattern block 20 is very little, circumferential bumps drop pattern block 20
The intensity of width W1 wider, sidewall are insufficient, and tire can not support the load of vehicle.Sidewall drop ridge design block 20 uses circular arc
The protrusion of face extending direction and the direction of advance of tread contour design in the same direction, it can be ensured that tire has air flowing when rolling
Help sizing material heat dissipation, improves heat dissipation performance, promote the endurance quality of tire.
As shown in FIG. 6 and 7, it is step-like right angle that the section of sidewall bumps drop pattern block 20, which may be alternatively provided as top,
Triangle, the height H9 of step protrusion is consistent with the height of circumferential concave-convex drop pattern block protrusion H8, and width W2 falls for bumps
The 25%-50% of the width W1 of poor pattern block 20.
It is designed from shallow to deep in conclusion the groove of tire tread is used from tread center toward tire shoulder, the side of groove
Wall is equipped with concave-convex drop groove, and sidewall design has sidewall bumps drop pattern block, passes through the concave-convex drop flower of tyre surface furrow bank
The position distribution and depth optimization of groove and the concave-convex drop pattern block on sidewall design, it can be ensured that the intensity of tyre surface and sidewall subtracts
The thickness of few tyre surface and sidewall, improves the heat dissipation performance of tyre surface and sidewall, promotes tire endurance quality.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with scope of protection of the claims
Subject to.
