Detailed Description
A tire includes a tread with a groove disposed thereon.
As shown in fig. 1 and 2, a tire tread groove 100 for improving stone removal performance includes a groove bottom surface 101 at the bottom of the groove 100 and groove wall surfaces 102 disposed on both sides of the groove bottom surface 101. The groove wall surface 102 is a slope that gradually flares outward from the groove bottom surface 101 toward the top of the groove 100, and specifically, the angle (inclination angle) between the groove wall surface 102 and the tread normal plane is 10 to 25 °, which facilitates the discharge of stones from the groove 100. It should be noted that it is not limited herein whether the groove wall surfaces 102 on both sides are symmetrical, that is, the groove wall surfaces 102 on both left and right sides may have the same inclination angle or different inclination angles.
As shown in fig. 2, a projection 200 is provided at the lower portion of the groove wall surface 102 so as to project from the surface, and the distance L1 between the side wall surface 201 of the projection 200 and the groove wall surface 102 is 0.5 to 3mm, that is, the projection 200 projects from the groove wall surface 102 by 0.5 to 3mm. And preferably the side wall surface 201 of the boss 200 and the groove wall surface 102 are parallel to each other. The lug boss 200 divides the groove 100 into an upper layer of groove and a lower layer of groove, wherein the width of the upper layer is larger than that of the lower layer, so that when stones enter the groove 100, the lug boss 200 positioned at the lower part of the groove 100 can block the stones and pop the stones out of the groove 100, and the stone removing effect of the groove 100 can be improved.
As shown in fig. 3, the upper surface of the boss 200 is a substantially zigzag stone discharge line 202, such as a broken line or a wavy line, the stone discharge line 202 is shaped like a mountain, and the stone discharge lines 202 extend along the extending direction of the groove 100. For the sake of visual description of the stone discharge line 202, an upper end point of the stone discharge line 202 is defined as a crest 203 and a lower end point of the stone discharge line 202 is defined as a valley 204 in the present embodiment. Wherein, the distance h1 between the mountain tops 203 and the top side line of the groove 100 is 3-15mm, and the heights of the mountain tops 203 are equal. The distance h2 between the valley 204 and the lowest point of the trench 100 is 3-15mm, and the height of each valley 204 is equal. The crests 203 and valleys 204 are arranged equidistantly staggered in the direction of extension of the trench 100, i.e. in fig. 3 the distance between the crests 203 and valleys 204 in the horizontal direction is equal, in particular the horizontal distance L2 between the crests 203 and valleys 204 is 5-15mm. The included angle alpha between two adjacent line segments on the stone removing line 202 is 45-90 degrees, and the stone removing performance is reduced if the intersection angle alpha is too large.
As shown in fig. 2, the sidewall surface 201 of the boss 200 and the groove bottom surface 101 are connected by a circular-arc chamfer 205, and the radius of the circular-arc chamfer 205 is 1mm at the minimum, thereby avoiding groove bottom breakage. The radius of the circular arc chamfer 205 may be a full chamfer at the maximum, i.e., tangent to all three surfaces formed by the side wall surfaces 201 of the left and right bosses 200 and the groove bottom surface 101.
The structure of the boss 200 has the following advantages: the boss 200 protrudes from the groove wall surface 102, so that the width of the lower layer of the groove 100 is smaller than that of the upper layer, stones can be blocked by the boss 200 when entering the groove 100 and do not enter the lower layer of the groove 100, meanwhile, the upper surface of the boss 200 is the serrated stone discharge line 202, so that the whole boss 200 has up-and-down fluctuation in the extending direction of the groove 100, when the stones enter the stone discharge line 202, the adjacent line segments on the stone discharge line 202 can generate extrusion force on the stones, and the stones are discharged from the stone discharge line 202, namely, the boss 200 improves the stone discharge performance of the tire.
As shown in fig. 1 to 3, a stone-discharging rubber nail 300 protruding upward is provided on the trench bottom surface 101, and the stone-discharging rubber nail 300 has a half-hill shape, where the half-hill shape is one of two half-hills formed by cutting a mountain body downward in a longitudinal direction at a mountain top of a complete mountain. The tangent plane (i.e. the plane formed by cutting) at one side of the stone discharging rubber nail 300 is connected to the side wall surface 201 of the boss 200, so that the thickness of the position on the groove 100 is increased, the puncture resistance is improved, meanwhile, the side surface of the stone discharging rubber nail 300 forms an inclined plane at the lower part of the groove 100, and when the stone contacts the inclined plane, the stone is sprung outwards by the reaction force of the inclined plane.
As shown in FIG. 3, the apex 301 of the stone binder nail 300 is located below the crest 203 of the boss 200, and specifically, the distance h3 between the apex 301 of the stone binder nail 300 and the crest 203 of the boss 200 is 2-5mm. I.e., the apex 301 of the stone cement 300 does not intersect the crest 203 of the boss 200.
As shown in fig. 3, a plurality of (generally 3 to 6) ridge lines 302 are uniformly arranged on the side surface of the stone discharging rubber nail 300, the ridge lines 302 extend downwards from the vertex 301 of the stone discharging rubber nail 300 to the bottom edge of the stone discharging rubber nail 300, and the ridge lines 302 may be straight lines or curves protruding upwards, so that when a stone contacts the side surface of the stone discharging rubber nail 300, the stone can be subjected to an outward reaction force due to the fact that the ridge lines 302 are straight lines or curves protruding upwards, and the stone can be popped outwards and cannot stay in the groove 100.
As shown in fig. 2, when viewed from the cross section of the groove 100, the vertex 301 of the stone discharging rubber nail 300 and the end point 303 farthest from the bottom of the stone discharging rubber nail 300 are respectively located at the left and right sides of the center line of the groove 100, i.e. when the vertex 301 is located on the boss 200 of the left groove wall surface 102, the end point 303 must be located at the right side of the center line, and is preferably located on the boss 200 at the right side, so that the span of the stone discharging rubber nail 300 in the width direction of the groove 100 can be extended, and when stones enter the lower layer of the groove 100, the stone discharging rubber nail 300 can be always contacted, and the stone discharging performance of the groove 100 can be ensured.
As shown in fig. 1, a plurality of stone-removing nails 300 (three in fig. 1) are disposed in the groove 100, the stone-removing nails 300 are generally arranged along the extending direction of the groove 100, and are preferably staggered with each other on the left and right groove wall surfaces 102 of the groove 100 (in fig. 1, the stone-removing nails are staggered up and down), and the stone-removing nails 300 are preferably evenly spaced in the extending direction of the groove 100 to ensure that the respective stone-removing performance is provided at each position of the groove 100.
The minimum distance between the stone discharge rubber nails 300 is 2-8mm, and the stone discharge rubber nails 300 cannot interfere with each other, so that the stone discharge rubber nails 300 are prevented from being too dense.
In summary, the present invention has the advantages that the width of the lower layer of the groove 100 is reduced by the boss 200, which is beneficial for discharging stones, and the upper surface of the boss 200 is the zigzag stone discharge line 202, which further enhances the stone discharge performance. The stone discharging rubber nails 300 are arranged at the bottoms of the grooves 100, the stone discharging rubber nails 300 are in a half-mountain shape, the side faces of the stone discharging rubber nails 300 are inclined planes, the stone discharging performance is further improved, the tire is effectively prevented from being pricked by sand, and the service life and the use safety of the tire are greatly improved. Meanwhile, the boss 200 and the half-hill-shaped stone discharge rubber nail 300 increase the surface area of the groove 100, namely increase the heat dissipation area of the groove 100, and improve the heat dissipation performance of the tire.
